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

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.


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_10.2010.19-1_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.

    uhmm when flashing the device it says.
    suitable usb device not found waiting……

    is this normal should i wait till its found? im waitinf for 3 minutes now….

    please help. dont want to brick my phone

    kind regards

      I also had suitable USB device not found, but for about 30 seconds.

      Even if something goes wrong with the flash, you can reflash again to fix it.
      This is what I did when I accidentally turned off flasher midway.

      Just make sure the .bin file names are typed correctly (specific to the ones you downloaded – the instructions only show global version)

        thanks for the reply.

        i got it flash succesfully.
        i just took out the cable and tried it again and it work just fine after that.

        so thanks great tutorial.
        i was really getting frustated that i could update with the nokia software updater.

        recommend it to everybody that cant update with NSU.

          No Probs,
          Glad it worked for you Ian.

          With flashing, there shouldn’t really be too much worry of bricking your phone as you can just flash again to fix it.

          This is also useful later on to “Hard Reset” your N900 if it ever gets bogged down with Extras Testing/Devel (geek level not ready for public) apps.

    Hi, copied the files and then moved them to the flasher program, for some reason my computer has moved them as VLC media files? So when I try to follow the above process my VLC media player starts and not the flashing process.

    Any ideas as to how to loose the VLC link?

    Cheers Mark

      Not sure, but perhaps temporarily uninstall VLC? Sorry, I don’t know why VLC is randomly opening that.

      When you say, try the above process, which step? The moving or the whole black box typing thingy?

    Thanks for getting back. It happens when I type or paste the command in the black box thingy. The instructions are really clear (even I can follow them!) It’s just my computer trying to see me off. What should the icon look like?

    • June 4, 2010 at 2:31 pm

      Hi Mark.

      What icon are you asking about, the .bin files?

      I’m on XP so my icon for the .bin file looks like one of those files that aren’t able to be opened by anything. (See screenshot)

      What files have you downloaded, are they exactly the same ones in the tutorial?

    I Know this is of-topic but will ask you anyways.
    since i installed the update my email doesnt work properly.
    before the updat my hotmail account was working fine but ever since the update
    it doesnt sync every 5 minutes as selected.
    i think i have the right setting bc i wrote then down before the update.
    can you help me with this bc this really sucks and if i cant get it fixed i think i will just get a other phone bc my email i very important to me.
    maybe theres a fix?
