Remove all date and return phone to original settings:
1. Download and install Flasher (http://wiki.maemo.org/Updating_the_tablet_firmware). I used Linuxx32 bit version on Linux 64 bit without problem. On linux you will need extract flasher, it is not necessary to setup. For windows read link.
2. Download on computer Images from site: http://tablets-dev.nokia.com/nokia_N900.php . You will need Vanilla image (RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin) and PR_combined (RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin or on your choice).
3. Fully charge the battery (IMPORTANT!!)
4. Unplug the USB cable from the device.
5. Turn off the device.
-----Flashing USER space ----------------------------
6. Execute the following command (in linux you have to be root!):
* Windows:

Code:

 flasher-3.5.exe -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f -R

* Linux

Code:

./flasher-3.5 -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f -R

Debian based Linux (e.g Ubuntu)

Code:

flasher-3.5 -F RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin -f -R

7. You will see something like:

Code:

 Image 'mmc', size 241163 kB
	Version RX-51_2009SE_1.2009.41-1.VANILLA
 Suitable USB device not found, waiting.

8. Plug Phone by USB to computer and wait until will get message that flashing finished. After this phone will reboot by self.

P.S Check file names for images! They can be different for different regions and language settings. I don't know it. One Image should be Vanilla and second PR.
