Dear All,

Here is the solution to fix this problem, i just fixed my N900 today.

From a windows PC

1.Download the flashing software.

The first software you need is called “Maemo Flasher”, and this is the program that needs to be installed on your PC and can be found here:

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

Download the latest version of Maemo Flasher (which is currently 3.5 at time of posting this), and make sure you download the .exe file.

Install that file.

2.Download image files for the N900 itself

These files can be found here:

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

2A.This page will ask you to enter your IMEI, with very clear instructions on where to find it.

Insert emei N900 hard reset

Follow the on screen prompts until you reach the download section.

There are two pieces of software you need to download from there.

1. eMMC content – This is the package to erase all data held on your 32GB storage.(For PR1.3 choose the one marked Latest)
2. OS – This is your operating system.

2B.There are two eMMC packages available, so download the Latest. For PR1.3 It’s called:

RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin

2C.The OS is a little more difficult to figure out which one you need.

The notes alongside the software lets you find the right package easier.

I found the best way to check is to do the following: (On the N900)

1. Menu
2. Settings
3. About Product

This will show you this image(or similar)

After that, you might seen Sim Disable Symbol Again, dont be sad.

Connect you N900 to any WiFi, and update your phone by going in Application and press update.

Maemo 5, 18 MB application will downloaded and installed, you N900 restart agian, now go to application manager again and update for Maemo add on 132 MB.

Once every thing finished, N900 restarts and you will find a new N900 with every thing working.
