In this post, I shall be taking you through the steps by steps of how you can manually flash Nokia N900 Maemo phone in the event that it develops serious software problems like rebooting, hanging freezing e.t.c. Also, you will have access to all the files needed to successfully complete this task

Latest Global Versions with PR 1.3

Nokia N900 PR_EMMC Contents Download

Disclaimer & Warning!

Backup the N900! This process will wipe your photos and videos. 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 your data onto N900 as that will get wiped. You can drag files back over and restore the backup from memory card afterward. And you must also know that I accept no responsibility for any damage that might occur to your phone as a result of you using this method. But I want to assure you that if you follow the process very carefully, you will hardly encounter any problem

Don’t Miss: Run Android Applications on Non-Android Devices(like meego maemo, and Apple Ios)

Steps to manually flash Nokia N900 Maemo Phone

• First off, download the latest firmware compatible with your n900. For the purpose of this tutorial, I download the global release of RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin and RX-51_2009SE_10.2010.19-1_PR_COMBINED_MR0_ARM.bin

– Global Release (Will vary depending on the package  you download

•  After downloading files 1 & 2 Above,  move both .bin files into “C:\Program Files\maemo\flasher-3.5″  see illustration above
• Ensure that your battery is fully charged
• Next, turn off N900. Then, 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 the top right corner. Do not at any point disconnect the cable or restart N900 until step 9.

• Step 5: On your PC, click Start>Run>CMD. You’ll see a black box appear.
• 6. Type or copy and paste

cd\programfiles\maemo\flasher-3.5

or

cd "%ProgramFiles%\maemo\flasher-3.5"

• Step 7. Type of copy and paste PR1.2 >>(Note, if you downloaded or 1.3 , replace it with same)

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 the global version.

Leave it for a couple of minutes while it flashes your N900 with PR1.2. as shown in the picture below:

And make sure you wait until it says “CMT Flashed successfully”.

• 8. Now copy and paste
  flasher-3.5 – F RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin -f -R

Then you will see success  a message as shown below:

Nokia N900 will attempt to restart.

• Step 9 which is the final step,  If Nokia N900 hasn’t already restarted, restart it manually. Congratulations, you are now on PR1.2/PR1.3 which is a newer version of the firmware and you have hard reset the N900.
• Lastly, restore your backup! For media files and you can 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 the size of the 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 or PR1.3
