COMPREHENSIVE FIRMWARE FLASHING GUIDE
for the NOKIA N9

PREPARE TO FLASH

If your phone has a low battery charge (less than 50%), plug it in and let it charge for a while. Then, make sure your phone is disconnected from any USB cables (including USB chargers). Power off the phone.

Go to the Flasher download site and download/install the version for your operating system (WinFlasher_3.12.1.exe, MacFlasher_3.12.1.dmg, flasher_3.12.1_i386.deb, or flasher_3.12.1_amd64.deb). Do not use Flasher 3.5 - it isn't compatible with the N9/N950. You can skip this step if you've already installed Flasher.

On Windows, open a Command Prompt with Administrator permissions (with UAC, right-click Command Prompt and select Run as administrator). On Linux, open a root shell (sudo -i/su). Change to the directory containing the firmware images you downloaded.

On Windows, run set PATH="C:\Program Files\Nokia\Flasher;%PATH%" in order to add Flasher to the system path.

FLASH THE PHONE

Run the following command, then connect the phone to your PC.

The current firmware version of your phone should appear. It is now time to flash.

Use the following list to determine which of the steps below you need to use to accomplish a particular task:

• Upgrade operating system: Replace operating system
• Recover from damaged OS install: Replace operating system
• "Unbrick" phone: Replace operating system or Comprehensive reset
• Reset back to a "clean slate": Comprehensive reset
• De-brand phone: Comprehensive reset
• Prepare for enabling open mode: Comprehensive reset
• Disable open mode: Comprehensive reset
• Prepare for selling, recycling, or destroying phone: Zeroize device
• Clear data before returning phone for warranty service (if possible): Zeroize device
• Reset device lock code: Zeroize device

Note that you should replace main.bin and emmc.bin in the commands with the actual names of the image files you are flashing.


Comprehensive reset (destroys user data)

The following commands will remove all data from your phone and restore it to factory state. The provided content files (sample music, wallpaper, etc.) will be restored.

Have few doubts since am using all this for the first time... Early apologies for stupid questions...

1. Do I need to change location for downloaded files to Flasher..!?

2. Is it possible to change both downloaded file names to main.bin and emmc.bin !?

3. In Windows 7, cmd.., which directory should I be in while processing all flashing commands..!!?

4. Comprehensive reset is the right method for factory reset, right..!? Have no intention to change my product code. Just need my phone to be factory restored. Everything erased including app data, contacts etc.. All personal data backed up.. (I am flashing since I have problems with missing shortcuts issue in menu, no twitter notification and few glitches here and there...).

Thank you..
