Free up rootfs space

2010-02-16T16:01:01Z

188.221.102.245: /* Use a script to move things from / to /home/opt/ */

Here's a simple howto for those suffering from lack of space in rootfs. The first suggestion is more of a temporary matter, for example to get enough space to install an update, but it's also the fastest and easiest.

The rest are more permanent (and thus more useful), but they require [[root access]].

=== Disable extras-testing and extras-devel and third party repositories===

Simply check the disabled box and save in the Application Manager's catalogues menu. wait for app manger to update the lists.
Of course this only helps if you actually had these repositories enabled.

Disabling extras-testing and extras-devel will (currently) give you an extra 11.5Mb in rootfs

=== Use apt cache outside of rootfs ===

If you run into a problem while using apt-get you can temporarily have the apt cache outside rootfs to be able to download larger deb files.

Create a download folder on the eMMC to be used for the downloaded packages instead of the defalut apt archive folder.

$ mkdir -p /home/user/MyDocs/apt-archive-cache/archives/partial

Now execute apt-get with the -o option:

apt-get -o dir::cache=/home/user/MyDocs/apt-archive-cache dist-upgrade

=== Optify python ===

If you have installed python or a python program before python was optified, you can optify it with this method:
first [[open a console]], then type the following commands:

sudo gainroot
apt-get install pymaemo-optify
apt-get clean

When the program is installed, type df -h in the xterm to see if it worked.
The output should now contain these lines at the end:

/opt/pymaemo/usr/lib/python2.5
2064208 471712 1487640 24% /usr/lib/python2.5
/opt/pymaemo/usr/share/pyshared
2064208 471712 1487640 24% /usr/share/pyshared
/opt/pymaemo/usr/lib/pyshared
2064208 471712 1487640 24% /usr/lib/pyshared
/opt/pymaemo/usr/share/python-support
2064208 471712 1487640 24% /usr/share/python-support
/opt/pymaemo/usr/lib/python-support
2064208 471712 1487640 24% /usr/lib/python-support

=== Remove non-optified packages ===

If you have installed programs from extras-testing, extras-devel or third party repositories, the programs might not be properly optified. Removing these might help with rootfs space.

You can free space by uninstalling applications that you do not need. A problem is if you do not know how these applications are called. To find it out:
* [[open a console]]
* start the application that you do not need
* in the console, type
ps -ef
You get a listing of all running processes, including the application you just started. To find out what package an application belongs to, enter
dpkg --search $(which ''processname'')

source:http://talk.maemo.org/showpost.php?p=468063&postcount=1

=== Use a script to move things from / to /home/opt/ ===

This script will move some files to /home/opt/ allowing rootfs space to be freed:

First, create a file, move-to-opt.sh for example, containing this script:

#!/bin/sh
# script for moving stuff from / to /home/opt to get more rootfs space on Nokia N900 Maemo 5
# ignoring errors when creating dirs that may already exist
mkdir -p /home/opt/usr/share/themes 2> /dev/null
mkdir -p /home/opt/usr/share/icons 2> /dev/null
mkdir -p /home/opt/usr/share/hildon-welcome 2> /dev/null
mkdir -p /home/opt/usr/share/pixmaps 2> /dev/null
mkdir -p /home/opt/var/cache/apt 2> /dev/null

cp -r /usr/share/themes/* /home/opt/usr/share/themes
rm -r /usr/share/themes
ln -s /home/opt/usr/share/themes /usr/share/themes

cp -r /usr/share/icons/* /home/opt/usr/share/icons
rm -r /usr/share/icons
ln -s /home/opt/usr/share/icons /usr/share/icons

cp -r /usr/share/hildon-welcome/* /home/opt/usr/share/hildon-welcome
rm -r /usr/share/hildon-welcome
ln -s /home/opt/usr/share/hildon-welcome /usr/share/hildon-welcome

cp -r /usr/share/pixmaps/* /home/opt/usr/share/pixmaps
rm -r /usr/share/pixmaps
ln -s /home/opt/usr/share/pixmaps /usr/share/pixmaps

cp -r /var/cache/apt/* /home/opt/var/cache/apt
rm -r /var/cache/apt
ln -s /home/opt/var/cache/apt /var/cache/apt

Make the script executable:
chmod +x move-to-opt.sh

Then run the script as root.

Updating the firmware

2010-02-08T04:55:31Z

188.221.102.245: /* N900: XP (SP3) / Vista (SP2) / Windows 7 32-bit */

Beware that flashing a new image on your device will reset the device back to factory defaults and remove all data not on the memory card: preferences, bookmarks, installed applications, with a single exception that any previously-set lock code will be kept and not reset to the factory-default of "12345".

The "Backup/Restore" application only saves a list of your repositories and installed applications (the applications you can reinstall after flashing), files in <code>/home/user/MyDocs</code>, some settings in <code>/home/user</code>, gconf and <code>/etc</code>, and additional files reported by applications on install. In general, properly packaged applications tell the backup tool what to back up, but if you've created extra shell scripts or files outside MyDocs, you'll have to back them up yourself.

== Updating & Flashing your device ==

For Windows, Mac or Linux you can use flasher-3.5 which can be download from the [http://tablets-dev.nokia.com/maemo-dev-env-downloads.php tablets-dev] page. This page contains all installation packages include documentation for using the flasher.

# Download the [[Flasher]] for your device model: [http://tablets-dev.nokia.com/maemo-dev-env-downloads.php N900, N810, N800] or [http://tablets-dev.nokia.com/d3.php 770]
# In the same directory, download the latest firmware image for your device model:
#* for [http://tablets-dev.nokia.com/nokia_N900.php N900]
#* for [http://tablets-dev.nokia.com/nokia_N810wimax.php N810 WiMAX Edition]
#* for [http://tablets-dev.nokia.com/nokia_N810.php N810]
#* for [http://tablets-dev.nokia.com/nokia_N800.php N800]
#* for [http://tablets-dev.nokia.com/nokia_770.php 770] (or, for the Hacker Editions, [http://tablets-dev.nokia.com/os2007_hacker_edition.php OS2007HE] and [http://tablets-dev.nokia.com/os2008_hacker_edition.php OS2008HE])
# Ensure the battery is fully charged.
# Unplug the charger and switch off the device.
# Connect the device to the computer via USB without turning it on.

=== Linux ===

Once you have downloaded the flasher and the fiasco-image, follow these steps:

<ol>
<li>Now turn off your device (''make sure you unplug the charger or else the device wont power down completely, you can plug the device back into power once it starts flashing'') and plug in the USB cable to a port on the computer and the port on your device.
<li>Now, open up a terminal and run: 
''It will ask you for an administrator password, enter it.''
</ol>
::<pre>sudo ./flasher-3.5 -F <FIASCO image> -f -R</pre>
<li> ''Note: If you installed from the .deb package, the command will omit the './''' (sudo flasher-3.5 -F <FIASCO image> -f -R). 
<ol start="4">
<li>It will say:
</ol>
::<pre>Suitable USB device not found, waiting</pre>
<ol start="5">
<li>N900: Remove USB, hold the u key and plug it back in. Wait until you get a boot screen with usb logo in top right, and let go of the key. 
N810, N800 and 770: First, unplug the power cord from the device, as this will prevent it from updating. Then take your device, and hold down the Home/Swap button (looks like a little house on the N800 and 770, and two overlapping rectangles on the N810), and while holding down the Home/Swap button press the power button to turn it on. 
''If it doesn't boot and start flashing, make sure the USB cable is plugged in.''
<li>It should start flashing and then reboot.
<li>You can remove the USB cable after it has booted to a normal desktop (just make sure to eject any cards that may have mounted on your computer).
</ol>

=== Mac OS X ===
There are two methods for flashing the device on OS X, using the GUI, with the 770Flasher application or using the console, much like the Linux flashing method. ''Both methods work fine for both the 770 and the N800/N810.''

==== GUI with 770Flasher ====
This is the easier of the two methods, and should be used by most people.

# Download the [http://maemo.org/downloads/product/PC/770flasher/ 770Flasher] (yes, it will work fine for flashing an N800 or N810). Latest flashers (Linux/Mac), which work also for N900, are also available on [http://tablets-dev.nokia.com/maemo-dev-env-downloads.php Latest Official Maemo Development Environment Page]
# Follow the [[Upgrading_tablet_OS#Flashing_your_Nokia_tablet|steps above]] to get the appropriate firmware image.
# Drag the firmware image (will end in .bin) onto 770Flasher.
# Follow the on-screen prompts.
# You should now see ''Suitable USB device not found, waiting'', switch on your device while holding the Home-button. Note for N810 users: switch on your device while holding the Swap button.
# Watch the messages as the image loads to the device after which it reboots automatically.

==== Console with Flasher-3.5 ====
These steps cover flashing the device with OS X using the Terminal. This is the more difficult than using [[Upgrading_tablet_OS#GUI_with_770Flasher|770Flasher]], but gives you access to the advanced options flasher-3.5 provides (like setting R&D flags, flashing only parts of the image, unpacking the image, etc).

<ol>
<li> Follow the [[Upgrading_tablet_OS#Flashing_your_Nokia_tablet|steps above]] to get the appropriate firmware image and flasher. 
<li>Now turn off your device (''make sure you unplug the charger or else the device wont power down completely'') and plug in the USB cable to a port on the computer and the port on your device. N900 users can't plug the usb cable yet as it would start recharging the battery.
<li>Now, open up the Terminal (it's in /Applications/Utilities/) and run: 
''It will ask you for an administrator password, enter it.''
</ol>
::<pre>sudo /usr/bin/flasher-3.5 -F <FIASCO image> -f -R</pre>
<ol start="4">
<li>It will say:
</ol>
::<pre>Suitable USB device not found, waiting</pre>
<ol start="5">
<li>First, unplug the power cord from the device, as this will prevent it from updating. Then take your device, and hold down the Home/Swap button (looks like a little house on the N800 and 770, and two overlapping rectangles on the N810 users do not need to hold down anything), and while holding down the Home/Swap button press the power button to turn it on. N900 users press u button and plug the usb cable. Release button when flashing process begins. 
''If it doesn't doesn't boot and start flashing, make sure the USB cable is plugged in.''
<li>It should start flashing and then reboot.
<li>You can remove the USB cable after it has booted to a normal desktop (just make sure to eject any cards that may have mounted on your Mac).
</ol>

=== Windows ===

==== N900: XP (SP3) / Vista (SP2) / Windows 7 32-bit ====
Microsoft Windows users wanting to update their [[N900]] can use the [http://europe.nokia.com/get-support-and-software/download-software/device-software-update Nokia Software Updater] or flash their devices (see the [[Flasher]] documentation.)

'''NOTE''': On Windows 7, install the current Nokia Software Updater (NSU) under compatibility mode or alternatively get the [http://nds2.betalabs.nokia.com/NokiaSoftwareUpdater/NokiaSoftwareUpdaterSetup_2.4.3EN.exe beta version 2.3.4] at [http://betalabs.nokia.com/apps/nokia-software-updater Betalabs] which now supports Windows 7.

It is possible to flash the N900 directly without using the NSU. This is handy when you like to update the device with the same firmware that is already installed on the N900 (reflash). The NSU will only update the N900 if there is a version newer than the one currently installed on the device.

In order to flash directly from the XP/Vista/Windows 7 command line, follow these steps:

# [http://tablets-dev.nokia.com/maemo-dev-env-downloads.php Download] and install the latest version of Flasher e.g. maemo_flasher-3.5_2.5.2.2.exe
# [http://tablets-dev.nokia.com/nokia_N900.php Download] the latest firmware (.bin) file and save it to %ProgramFiles%\maemo\flasher-3.5\ (the default installation path for Flasher) or to the custom path of your choice.
# Ensure the battery is at least half full.
# Unplug charger cable and switch off the device.
# Open the Command Prompt (Start then Run or Windows Logo key + R) and type '''cmd''' then press Enter.
# Change the directory to the Flasher's path (TIP: Use the TAB key to auto-complete the commands and file-names)
:: <pre> cd "%ProgramFiles%\maemo\flasher-3.5" </pre>
# Hold the ''u'' key on the keyboard and connect the USB cable at the same time (details on the [http://wiki.maemo.org/Flasher wiki])
# Run the following command:
::<pre>flasher-3.5.exe -F RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin -f -R</pre>

Replace ''RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin'' with the firmware you wish to update. There are specific firmwares for N900 UK devices, go to [http://wiki.maemo.org/Maemo_UK_variant_firmware Maemo UK variant firmware]

The update will take approximately 4 minutes after which the N900 will reboot and display the Welcome Screen with Regional settings.

==== N900: Vista (64bit) ====
According to [http://talk.maemo.org/showpost.php?p=411019&postcount=67 this] post, you need to turn on the loading of unsigned drivers. This is done by choosing the option "Boot without checking for signed drivers" (or something similar) in the boot-menu. To display the boot-menu press the "F8" key as soon as the windows boot process starts. The rest of the process is similar to XP.

==== N900: Vista & 7 (64bit) ====
An alternative approach is to either download [http://www.ubuntu.com/getubuntu/download Ubuntu LiveCD] and burn it to cd or create a [https://wiki.ubuntu.com/LiveUsbPendrivePersistent persistent installation] to usb disk. After that you must get (another) usb stick where you will download [http://tablets-dev.nokia.com/maemo-dev-env-downloads.php maemo_flasher-3.5_2.5.2.2_i386.deb] -file (versions may vary) '''and''' firmware files needed for reflashing. Additionally one can save this page to usb stick just in case.

After that you only boot your LiveCD or persistent Ubuntu, install [[Flasher]] (doubleclick the file should work fine) and after that follow instructions from Linux - chapter.

==== N770/N800/N810 ====
Internet Tablet users can go to the appropriate support page for their device ([https://www.nokiausa.com/A41271130 N810 WiMAX Edition], [https://www.nokiausa.com/A4686323 N810], [https://www.nokiausa.com/A4410958 N800], or [http://europe.nokia.com/A4144790 770]), download and install the Software Update Wizard, run it and follow the on-screen prompts.

=== Flashing the eMMC in the N900 ===
Flasing the eMMC resets the MyDocs folder contents to factory settings. N900 users don't need to reflash the eMMC of their device. If you are reading this it's probably because you got a pre-production device e.g. in the Maemo Summit. If you have a sales unit and you have problems with your eMMC you should contact Nokia Care.

Also note that '''any backups created in your MyDocs area will need to be copied off the device to be safe across an eMMC flash''' as the MyDocs area and other partitions on /dev/mmcblk0 will be erased.

Note that the eMMC images available do not contain pre-loaded maps. If you reflash your eMMC you will lose them (the Maps application will work as usual but you will need to download the maps needed).

In order to flash the eMMC, follow these steps:
* Fully charge the battery (IMPORTANT!!)
* Unplug the USB cable from the device.
* Turn off the device.
* Install [[Flasher]] for your OS (Linux, Mac OS X or MS Windows)
* Grab the Vanilla eMMC image (.bin file) from [http://tablets-dev.nokia.com/nokia_N900.php the Nokia repository]
* Navigate to the directory where the image file was saved.
* Plug in the USB cable into the computer.
* Execute the following command (in linux you have to be root!):
::* Windows
::<pre>flasher-3.5.exe -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f -R</pre>

::* Linux
::<pre>./flasher-3.5 -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f -R</pre>

:: Debian based Linux (e.g Ubuntu)
::<pre>flasher-3.5 -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f -R</pre>
* Text similar to the following will be displayed on the computer:
<pre>
flasher v2.5.2 (Oct 21 2009)

Image 'mmc', size 241163 kB
Version RX-51_2009SE_1.2009.41-1.VANILLA
Suitable USB device not found, waiting.
</pre>
* Plug the USB cable into the N900.
* The dim Nokia screen will be displayed for a few seconds followed by progression dots. Text similar to the following will be displayed on the computer:
<pre>USB device found found at bus 001, device address 006.
Found device RX-51, hardware revision 2101
NOLO version 1.4.13
Version of 'sw-release': RX-51_2009SE_1.2009.42-11.002_PR_002
Booting device into flash mode.

Image(s) flashed successfully in 26.848 s (8982 kB/s)!
</pre>
* The flash will take around 1 minute after which the device will reboot.
* The bright Nokia screen will come up on the screen with the USB icon on the top right followed by progression dots with yellow LED blinking for a few seconds. The device will then turn off and go into charging mode with the yellow LED blinking (NOTE: If the device appears to reboot, unplug the cable.)
* Unplug cable and wait for device to turn off completely. You may hear a sound (punk) of the device turning off.
* Having flashed the eMMC, you should now flash the [[#Flashing your device|firmware of your device]].

== Seamless Software Update ==
{{main|Seamless Software Update}}
[http://en.wikipedia.org/wiki/Maemo_(operating_system)#SSU SSU] is Nokia's new method for upgrading the devices over-the-air without requiring a reflash. When Nokia pushes an update over SSU, you will see an update notification and be given the option to install the update—just like with your computer.

Generally speaking, SSU updates should be relatively pain-free, but there are a few issues to watch out for.
* If you have an aftermarket kernel or intifs installed (like the rotation support kernel or [[Booting_from_a_flash_card#Install_bootmenu|fanoush's bootmenu]]) and a kernel or initfs upgrade is pushed, they will be overwritten and you'll need to wait for your kernel or the bootmenu to be updated to reinstall them.
* If you have extensively modified the home directory for user "user", such as moved all the documents to a memory card or removing or leaving empty some of the subdirectories

If the update doesn't show up for you at all, you may have accidentally (or intentionally) uninstalled osso-software-version-rx*4, which is required to update. You can get it back by simply running an <code>apt-get install osso-software-version-rx34</code>, for the N800, and an <code>apt-get install osso-software-version-rx44</code>, for the N810. Then updating your repository list in Application manager.

If the packages that caused osso-software-version-rx*4 to be removed are still installed, they will need to be removed completely (in the case of conflicting packages). Alternatively, for packages which are simply newer than those specified by osso-software-version-rx*4, you can install osso-software-version-rx*4-unlocked, which does not have strict dependencies.

On N900 (probably also previous devices), it's possible the application manager ends up with message stating that it's required to upgrade using the Nokia PC application. In this case please check out [[OTA to PR1.1 troubleshooting]].

You can show the list of packages that are not going to be ugraded with <code>apt-get update && apt-get upgrade</code>. In that case, you can try using <code>apt-get dist-upgrade</code> command (as root, the app manager has to be shut down) to override. '''This is not supported because you can break future updates'''.

== Troubleshooting ==

* If you get a "Permission denied" error then chmod +x flasher-2.0 or chmod +x flasher-3.0 to make the flasher tool executable. You may also need root permissions, run command with sudo or su to root.
* If you need to flash your Nokia 770 with an image from 2005 then use the [http://tablets-dev.nokia.com/d3.php older flasher] called "flasher" with no number in the name
* If you get "Error claiming USB interface: Device or resource busy" error, as root, run "modprobe -r cdc_phonet"

===USB===
It may help to connect directly to the computer USB ports, avoiding the use of a hub - which includes the USB ports on laptop docking stations. The USB ports in the back of a laptop may also be better than using those in the front.

Some distributions do not present the USB device in the way that it expects it. First, see if it is necessary to "mount" USB:

<pre>mount -t usbfs usbfs /proc/bus/usb</pre>

If that does not work, try patching the ''flasher'' code. This replaces the use of /proc/bus/usb with the newer /dev/bus/usb filesystem:

<pre>perl -pi -e 's-/proc/bus/usb-/dev/bus/usb\000-;' -i.backup $FLASHER</pre>

Replace $FLASHER with the path to your flasher-2.0 or flasher-3.0 Linux binary.

These steps cover flashing the device with OS X using the Terminal. This is the more difficult than using [[Upgrading_tablet_OS#GUI_with_770Flasher|770Flasher]], but gives you access to the advanced options flasher-3.5 provides (like setting R&D flags, flashing only parts of the image, unpacking the image, etc).

<ol>
<li> Follow the [[Upgrading_tablet_OS#Flashing_your_Nokia_tablet|steps above]] to get the appropriate firmware image and flasher. 
<li>Now turn off your device (''make sure you unplug the charger or else the device wont power down completely'') and plug in the USB cable to a port on the computer and the port on your device. N900 users can't plug the usb cable yet as it would start recharging the battery.
<li>Now, open up the Terminal (it's in /Applications/Utilities/) and run: 
''It will ask you for an administrator password, enter it.''
</ol>
::<pre>sudo /usr/bin/flasher-3.5 -F <FIASCO image> -f -R</pre>
<ol start="4">
<li>It will say:
</ol>
::<pre>Suitable USB device not found, waiting</pre>
<ol start="5">
<li>First, unplug the power cord from the device, as this will prevent it from updating. Then take your device, and hold down the Home/Swap button (looks like a little house on the N800 and 770, and two overlapping rectangles on the N810 users do not need to hold down anything), and while holding down the Home/Swap button press the power button to turn it on. N900 users press u button and plug the usb cable. Release button when flashing process begins. 
''If it doesn't doesn't boot and start flashing, make sure the USB cable is plugged in.''
<li>It should start flashing and then reboot.
<li>You can remove the USB cable after it has booted to a normal desktop (just make sure to eject any cards that may have mounted on your Mac).
</ol>

=== Windows ===

==== N900: XP (SP3) / Vista (SP2) / Windows 7 ====
Microsoft Windows users willing to update the [[N900]] can use the [http://europe.nokia.com/get-support-and-software/download-software/device-software-update Nokia Software Updater] or see the [[Flasher]] documentation.

'''NOTE''': at this moment i've downloaded italian version of NSU and to make it work with Windows 7, i configured it for Vista compatibility.--[[User:pippomu|pippomu]] 16:18, 14 January 2010 (UTC)

It is possible to flash the N900 directly without using the Nokia Software Updater (NSU). This is handy when you like to update the device with the same firmware that is already installed on the N900 (reflash). The NSU will update only if there is a version newer than the one installed on the device.

To flash directly from the XP/Vista/Windows 7 command line, follow these steps:
* [http://tablets-dev.nokia.com/maemo-dev-env-downloads.php Download] and install the latest version of Flasher (e.g. maemo_flasher-3.5_2.5.2.2.exe)
* [http://tablets-dev.nokia.com/nokia_N900.php Download] the latest firmware (.bin) file and save to %ProgramFiles%\maemo\flasher-3.5\ (default installation path of Flasher) or to the custom path of your choice.
* Fully charge the battery.
* Unplug charger and switch off the device.
* Open the Command Prompt by going to Start then Run (or Windows Logo key + R) and type '''cmd''' then press Enter.
* Change directory to the flasher's program path (TIP: Use the TAB key to auto-complete the commands and file-names)
:: <pre> cd "%ProgramFiles%\maemo\flasher-3.5" </pre>
* Connect the USB cable while hold 'u' key on the N900 (details on the [http://wiki.maemo.org/Flasher wiki])
* Run the following command:
::<pre>flasher-3.5.exe -F RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin -f -R</pre>

Remember to replace the ''RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin'' with the firmware you wish to update with. For UK devices, go to [http://wiki.maemo.org/Maemo_UK_variant_firmware Maemo UK variant firmware]

The update will take about 3 minutes after which the N900 will reboot and display the Welcome screen with Regional settings.

==== N900: Vista (64bit) ====
According to [http://talk.maemo.org/showpost.php?p=411019&postcount=67 this] post, you need to turn on the loading of unsigned drivers. This is done by choosing the option "Boot without checking for signed drivers" (or something similar) in the boot-menu. To display the boot-menu press the "F8" key as soon as the windows boot process starts. The rest of the process is similar to XP.

==== N900: Vista & 7 (64bit) ====
An alternative approach is to either download [http://www.ubuntu.com/getubuntu/download Ubuntu LiveCD] and burn it to cd or create a [https://wiki.ubuntu.com/LiveUsbPendrivePersistent persistent installation] to usb disk. After that you must get (another) usb stick where you will download [http://tablets-dev.nokia.com/maemo-dev-env-downloads.php maemo_flasher-3.5_2.5.2.2_i386.deb] -file (versions may vary) '''and''' firmware files needed for reflashing. Additionally one can save this page to usb stick just in case.

After that you only boot your LiveCD or persistent Ubuntu, install [[Flasher]] (doubleclick the file should work fine) and after that follow instructions from Linux - chapter.

==== N770/N800/N810 ====
Internet Tablet users can go to the appropriate support page for their device ([https://www.nokiausa.com/A41271130 N810 WiMAX Edition], [https://www.nokiausa.com/A4686323 N810], [https://www.nokiausa.com/A4410958 N800], or [http://europe.nokia.com/A4144790 770]), download and install the Software Update Wizard, run it and follow the on-screen prompts.

=== Flashing the eMMC in the N900 ===
Flasing the eMMC resets the MyDocs folder contents to factory settings. N900 users don't need to reflash the eMMC of their device. If you are reading this it's probably because you got a pre-production device e.g. in the Maemo Summit. If you have a sales unit and you have problems with your eMMC you should contact Nokia Care.

Also note that '''any backups created in your MyDocs area will need to be copied off the device to be safe across an eMMC flash''' as the MyDocs area and other partitions on /dev/mmcblk0 will be erased.

Note that the eMMC images available do not contain pre-loaded maps. If you reflash your eMMC you will lose them (the Maps application will work as usual but you will need to download the maps needed).

In order to flash the eMMC, follow these steps:
* Fully charge the battery (IMPORTANT!!)
* Unplug the USB cable from the device.
* Turn off the device.
* Install [[Flasher]] for your OS (Linux, Mac OS X or MS Windows)
* Grab the Vanilla eMMC image (.bin file) from [http://tablets-dev.nokia.com/nokia_N900.php the Nokia repository]
* Navigate to the directory where the image file was saved.
* Plug in the USB cable into the computer.
* Execute the following command (in linux you have to be root!):
::* Windows
::<pre>flasher-3.5.exe -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f -R</pre>

::* Linux
::<pre>./flasher-3.5 -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f -R</pre>

:: Debian based Linux (e.g Ubuntu)
::<pre>flasher-3.5 -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f -R</pre>
* Text similar to the following will be displayed on the computer:
<pre>
flasher v2.5.2 (Oct 21 2009)

Image 'mmc', size 241163 kB
Version RX-51_2009SE_1.2009.41-1.VANILLA
Suitable USB device not found, waiting.
</pre>
* Plug the USB cable into the N900.
* The dim Nokia screen will be displayed for a few seconds followed by progression dots. Text similar to the following will be displayed on the computer:
<pre>USB device found found at bus 001, device address 006.
Found device RX-51, hardware revision 2101
NOLO version 1.4.13
Version of 'sw-release': RX-51_2009SE_1.2009.42-11.002_PR_002

Image(s) flashed successfully in 26.848 s (8982 kB/s)!
</pre>
* The flash will take around 1 minute after which the device will reboot.
* The bright Nokia screen will come up on the screen with the USB icon on the top right followed by progression dots with yellow LED blinking for a few seconds. The device will then turn off and go into charging mode with the yellow LED blinking (NOTE: If the device appears to reboot, unplug the cable.)
* Unplug cable and wait for device to turn off completely. You may hear a sound (punk) of the device turning off.
* Having flashed the eMMC, you should now flash the [[#Flashing your device|firmware of your device]].

== Seamless Software Update ==
{{main|Seamless Software Update}}
[http://en.wikipedia.org/wiki/Maemo_(operating_system)#SSU SSU] is Nokia's new method for upgrading the devices over-the-air without requiring a reflash. When Nokia pushes an update over SSU, you will see an update notification and be given the option to install the update—just like with your computer.

Generally speaking, SSU updates should be relatively pain-free, but there are a few issues to watch out for.
* If you have an aftermarket kernel or intifs installed (like the rotation support kernel or [[Booting_from_a_flash_card#Install_bootmenu|fanoush's bootmenu]]) and a kernel or initfs upgrade is pushed, they will be overwritten and you'll need to wait for your kernel or the bootmenu to be updated to reinstall them.
* If you have extensively modified the home directory for user "user", such as moved all the documents to a memory card or removing or leaving empty some of the subdirectories

If the update doesn't show up for you at all, you may have accidentally (or intentionally) uninstalled osso-software-version-rx*4, which is required to update. You can get it back by simply running an <code>apt-get install osso-software-version-rx34</code>, for the N800, and an <code>apt-get install osso-software-version-rx44</code>, for the N810. Then updating your repository list in Application manager.

If the packages that caused osso-software-version-rx*4 to be removed are still installed, they will need to be removed completely (in the case of conflicting packages). Alternatively, for packages which are simply newer than those specified by osso-software-version-rx*4, you can install osso-software-version-rx*4-unlocked, which does not have strict dependencies.

On N900 (probably also previous devices), it's possible the application manager ends up with message stating that it's required to upgrade using the Nokia PC application. In this case please check out [[OTA to PR1.1 troubleshooting]].

You can show the list of packages that are not going to be ugraded with <code>apt-get update && apt-get upgrade</code>. In that case, you can try using <code>apt-get dist-upgrade</code> command (as root, the app manager has to be shut down) to override. '''This is not supported because you can break future updates'''.

== Troubleshooting ==

* If you get a "Permission denied" error then chmod +x flasher-2.0 or chmod +x flasher-3.0 to make the flasher tool executable. You may also need root permissions, run command with sudo or su to root.
* If you need to flash your Nokia 770 with an image from 2005 then use the [http://tablets-dev.nokia.com/d3.php older flasher] called "flasher" with no number in the name
* If you get "Error claiming USB interface: Device or resource busy" error, as root, run "modprobe -r cdc_phonet"

===USB===
It may help to connect directly to the computer USB ports, avoiding the use of a hub - which includes the USB ports on laptop docking stations. The USB ports in the back of a laptop may also be better than using those in the front.

Some distributions do not present the USB device in the way that it expects it. First, see if it is necessary to "mount" USB:

<pre>mount -t usbfs usbfs /proc/bus/usb</pre>

If that does not work, try patching the ''flasher'' code. This replaces the use of /proc/bus/usb with the newer /dev/bus/usb filesystem:

<pre>perl -pi -e 's-/proc/bus/usb-/dev/bus/usb\000-;' -i.backup $FLASHER</pre>

Replace $FLASHER with the path to your flasher-2.0 or flasher-3.0 Linux binary.
