Installation

= Warning =

Beware that flashing a new image on the Nokia tablet will remove all user changes to the system, including preferences, bookmarks, news feeds, user installed applications... Everything not on the memory card will be gone and the device will behave as if just purchased with the single exception that any previously set lock code will be kept and not reset to the factory-default of &quot;12345&quot; (even the code is not preserved on some images).

Note that Nokia's Backup tool only backs up stuff like bookmarks and documents inside /home/user/MyDocs -- It will probably be worthwhile experimenting a bit with the backup/restore utility before flashing :-)

= Required informations =

Before you start downloading Flasher and system image you need to read your tablet's 12-digit product ID which is printed on the tablet's packaging and on the label underneath the tablet's battery, and displayed in the Control Panel (field WLAN MAC address in Control Panel > Device > About Product). To find the identification number printed on your device, do the following:


 * Switch the device off.
 * Disconnect the charger from the device.
 * Open the battery cover and remove the battery.

The identification number is printed on the label underneath the battery. The identification number is given separately for WLAN and Bluetooth connections, and it consist of 12 characters.

= Needed downloads =


 * Linux flasher 3.0 (works for all tablets)
 * Linux flasher 2.0 (if you want to flash OS2005 on Nokia 770)
 * In the same directory download the system image you want from one of following locations:
 * Nokia 770 images
 * Nokia N800 images
 * Nokia N810 images

= Flashing procedure =

If you want to update to the latest Nokia image, follow the steps below:

chmod 755 ./flasher-3.0 ./flasher-3.0 -f -R -F NAME_OF_SYSTEM_IMAGE
 * Make sure the battery of your tablet is fully charged.
 * Tablet: Unplug charger and switch off. Connect it to your computer via USB without turning it on.
 * PC: Execute as root (or as a normal user with rights to use the USB port):
 * PC: &quot;Suitable USB device not found, waiting&quot; is displayed on the console
 * Tablet: Now plug in the charger to switch on the device or switch it on using the power button WHILE holding the Home-button
 * PC: Watch the messages as the image loads to the tablet after which it reboots automatically -- you're done now!

= Troubleshooting =

perl -pi -e 's-/proc/bus/usb-/dev/bus/usb\000-;' -i.backup flasher-3.0
 * If you get a &quot;Permission denied&quot; error then `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.
 * It may help, if you connect the tablet directly to your computer by USB, instead of a USB hub. Also, avoid the USB ports on laptop docking stations.
 * On some distributions the usb filesystem is not loaded
 * If you are running a newer kernel and you get &quot;Suitable USB device not found, waiting&quot; but nothing happens when you switch on the tablet as instructed above, try to patch the flasher:
