If you want to totally start fresh and have your device back to an "out of the box" state then this will help.

First we need to download a couple of things,

Grab a copy of the flasher from,

http://tablets-dev.nokia.com/maemo-d...-downloads.php

Then grab a copy of both the eMMC image and also the OS from,

http://tablets-dev.nokia.com/nokia_N900.php

Both files needed are named as follows,

RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin
RX-51_2009SE_1.2009.41-1.VANILLA_PR_EMMC_MR0_ARM.bin

You will need a copy of your IMEI number for Authentication for the OS and eMMC download. Which can be obtained from taking out your battery or logging in to your Nokia account.

Once you have downloaded all three files you will need to run the flasher-3.5.exe and install it.
Once the flasher has installed you will need to navigate to where the programme installed (c:\Program Files\maemo\)
You will then need to copy both the eMMC and the OS files in to folder.

You will then need to turn your device of and connect it to you PC via the USB cable while pressing the U key on the keyboard (This sets the device in flashing mode). If this is done correctly you will see a NOKIA sign across the screen and a USB sign in the top right corner. Also note that the display does not light up.

Now you launch a command prompt (Start, Run, cmd)

Once inside the command prompt you will need to change the directory with the following command,

cd "c:\Program Files\maemo\flasher-3.5"

Now you are in the directory of the flasher we will start to flash the eMMC first with the following command,

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

The flasher will now begin, If you see the following message "suitable USB device not found, waiting." please disconnect wait for a few seconds and then reconnect whilst holding the U key on the keyboard. If this still does not work please try a different USB port. The flasher will then start to flash the device.

Now that the eMMC has been flashed you can flash the OS,

Whilst still in the command prompt enter the below,

flasher-3.5.exe -F RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin -f -R

You will now see the flasher begin to flash the OS, if you see the message "suitable USB device not found, waiting." please follow the same procedure as you did when flashing the eMMC.

Once the device has been completely flashed it should boot up and will be as new.

Hope this helps.
