1 N900
[edit]
Updating the firmware using the Nokia Software Updater
Microsoft Windows users who wish to
update their N900 can use the
Nokia Software Updater (aka NSU), or use the Flasher (see section below).
The Nokia Software Updater is compatible with Windows XP Service Pack 3, Windows Vista Service Pack 2, and Windows 7. (Some users may encounter problems due to varying causes.)
The Nokia Software Updater can only be used when updating from a previous firmware to a new one. To reflash with the same firmware you currently have, or if you missed an update, use the flasher.
[edit] Updating or re-flashing the firmware using the Flasher Note: This method is fully compatible with 32 bit versions of Windows; 64-bit users may encounter problems.
To flash from the Windows (XP, Vista, or 7) command line,
- Download and install the latest version of the Flasher.
- Download the latest firmware (.bin) file for your region and save it to %ProgramFiles%\maemo\flasher-3.5\, or wherever you installed the Flasher.
- Ensure the battery is at least half full.
- Unplug USB cable if present, and switch off the device.
- Run the Flasher from the Start menu
- This is an alternate to step 5, if you have already opened the Flasher, ignore this step. Open the Command Prompt (Start then Run or Windows Logo key + R) and type cmd then press Enter. Change the directory to where you installed the Flasher (TIP: Use the TAB key to auto-complete commands and file-names)cd "%ProgramFiles%\maemo\flasher-3.5"
- Hold the u key on the device keyboard and connect the USB cable at the same time. See the Flasher documentation for more information. (TIP: Hold the u key until Windows has successfully installed the driver.)
- Run the following command:flasher-3.5.exe -F RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin -f -R
Replace RX-51_2009SE_2.2009.51-1_PR_COMBINED_MR0_ARM.bin with the firmware you wish to update. The latest PR1.2 official (rootfs) images are listed below:
