Right now there is no direct way as with other Nokia mobile to hard rest Nokia N900
But it can be done following below mentioned steps. A word of caution, before hard resting your mobile don’t forget to back up all your mobile information like contacts, messages, notes etc. and also all the data from your 32 GB mobile storage as after hard reset all data will be lost and your mobile will start as if it is starting first time.
I have tried the steps mentioned below on my Nokia N900 and it works fine, but there is absolutely no responsibility from my side if something goes wrong during hard reset process.
That’s why it is highly advice to back up your data and finish all the steps mentioned below.
Although during my mobile’s hard reset I wasn’t able to finish all the steps myself as I downloaded wrong file ( :D happens many a times), and still no harm was made to my mobile. So just follow the steps and it will work fine J
This tutorial is written to be used from a windows PC, but with slide changes it can be used from Linux based PC also. I will try to put one more tutorial on how to Hard reset NOKIA N900 using a Linux PC but for while it’s only indented for Windows PC
Step 1: Download flashing software
You need to download “Maemo Flasher”, it needs to be installed in computer to perform hard reset
The page will be somewhat like this.
From the list choose the appropriate version (In my first attempt I downloaded the wrong one and it gave me error when I used it)
The link is shown in Green rectangle box (Win Flasher_3.11.5.exe). Install the application after downloading.
Step 2: Image files for NOKIA N900
The file can be found here:
It will be something like this
In order to download the file, you will need to provide your device's 15-digit IMEI number and accept the end-user software agreement. How to find the IMEI number is given on top of the link itself.
There are two files 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.
There are multiple eMMC packages available, so download the Latest. At the time of writing this post it is PR1.3and It’s called:
RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin
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)
Download the OS package that exactly matches your device. In my first attempt I downloaded the package for India region
RX-51_2009SE_20.2010.36-2.004_PR_COMBINED_004_ARM.bin (India)
Where I needed to use
RX-51_2009SE_20.2010.36-2.003_PR_COMBINED_003_ARM.bin (Middle East and North Africa)
Therefore just be a bit careful while downloading the exact file matching your device.
Step 3: Copy these to files in the installed “Maemo Flasher” folder.
If u have installed it in “c:\program files\maemo\flasher-3.5”, then put these two files in this folder
You should now have two .bin files in the directory above.
Step 4:Updating the NOKIA N900 OS
1. Your battery should be as much as full as possible to prevent any crashes which could leave your mobile dead.
2. Turn your Nokia N900 off.
3. Press and hold the U key on the keypad.
4. Insert the USB cable, into a USB port, NOT a USB adapter. (A USB symbol should appear on the top right of your N900 screen, and also the Nokia logo in the centre).
5. You can now let go of the U key.
6. On your PC: Navigate to the Start Menu and select Maemo>Maemo Flasher 3.5>Maemo Flasher 3.5 or just go into the folder where “Maemo flasher” is install and run the exe directly.
7. In the command window you should now see: C:\Program Files\maemo\flasher-3.5>
8. Type: flasher-3.5 -F RX-51_2009SE_20.2010.36-2.002_PR_COMBINED_002_ARM.bin –f
The name of file might change according to region and version you downloaded. It’s a good practice to use tab for completing the name of file so u can get rid of trouble of writing name exactly
9. You should see something like this on your terminal
10.
Your personal data, such as Contacts, Images, SMS will still be on the device.
So if you want to remove these as well, follow the next steps.
So if you want to remove these as well, follow the next steps.
10. Do not disconnect or reboot the device the device. Just leave as is for now.
Step 5: Resetting the Mass Memory
Type in the command window:
flasher-3.5 -F RX-51_2009SE_10.2010.13-2.VANILLA_PR_EMMC_MR0_ARM.bin -f –R
Again the name of file might change according to region and version you downloaded.
This image below shows the completed reset of the eMMC (32GB HDD), in the command prompt on your PC.
This would have now removed any data you had stored there. Including Music, Photos, Contacts, SMS.
This completes the hard reset procees of your N900. You will get the restart screen on your mobile. If it is not restarting then restart it manually and u will get configuration screen on your mobile which u get on first run
Congratulation!!!!!!!!! You have successfully hard reset your Nokia N900
