How To: Manually Update N900 firmware to PR1.2 / Hard Reset Nokia N900 (updated with images) v10.2010.19-1

| June 2, 2010 | 17 Replies

Still stuck on 3.2010.02-8 for your N900? App Manager and Nokia Software Updater not showing any PR1.2 updates?

Manually update to PR1.2! It’ll take 5 minutes (not counting download time of files)

We’ve updated the post on Hard Resetting/Flashing N900 for PR1.2 this time, simplified even more with images to guide you through the process of updating N900 firmware/hard resetting N900.

(These instructions can also be used to hard reset N900 at a later stage when you want to freshen it up a few months down the line)

You will need:

  • N900
  • PC
  • Micro USB Cable
  • Your IMEI number (go to settings>About Product or under your N900 battery)

Before you look at the instructions:

Backup the N900!

This process will DELETE everything on the N900, including your photos and videos and other things you may have downloaded. Save precious data onto your computer. Simply drag and drop them over.

For content such as contacts/settings/bookmarks/applications list, use the Backup application on the N900, but backup to a memory card only. Do not back up onto N900 as that will get wiped.

You can drag files back over and restore backup from memory card afterwards.

INSTRUCTIONS

1. Download and install Maemo 5 Flasher (Appropriate for your PC operating System – these instructions are for windows so download the windows one)

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

2. Download PR 1.2 and eMMC content. You’ll need your IMEI

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

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

RX-51_2009SE_10.2010.19-1_PR_COMBINED_MR0_ARM.bin << Global Release (Will vary depending on which one you download)

3. Move both .bin files to C:\Program Files\maemo\flasher-3.5

4. Turn off N900. Connect MicroUSB cable but not N900. Whilst holding “U” on N900’s keyboard, attach to MicroUSB.

The Nokia logo will appear and a USB icon in top right corner. Do not at any point disconnect the cable or restart N900 until step 9.

5. On the PC, click Start>Run>CMD. You’ll see a black box appear.

6. Type or copy and paste into flasher

cd\program files\maemo\flasher-3.5

7. FLASHING PR1.2: Type of copy and paste into flasher >>

flasher-3.5 -F RX-51_2009SE_10.2010.19-1_PR_COMBINED_MR0_ARM.bin -f

note, the file name will differ slightly with each PR1.2 regional variant. The above is for global version.

Leave it for a couple of minutes whilst it flashes your N900 with PR1.2.

Wait until it says “CMT Flashed successfully”.

8. Flashing eMMC. Now copy and paste

flasher-3.5 -FRX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin -f -R

Wait for it to finish…

You’ll know it’s finished when it says

“Flashed successfully…..”

N900 will attempt to restart.

9. If N900 hasn’t already restarted, restart it manually. Congratulations, you are now on PR1.2 / Have hard reset N900.

10. Restore your backup! For media files and whatnot, just drag and drop back to N900 from your PC.

For contacts/bookmarks/settings/applications list, go to N900 backup app and restore. It’ll take a minute or two depending on size of backup and manually restart.

Everything will be set back to how it was before the reset except for apps. With apps, N900 gives you an app list of previously installed apps and will ask you which ones (if any) you want to reinstall.

After that, you now have PR1.2 / Hard Reset your N900.
