FLASHING FIRMWARE



To flash directly from the XP command line, follow these steps:

* Download and install the latest version of Flasher (e.g. maemo_flasher-3.5_2.5.2.2.exe)
* Download the latest firmware (.bin) file and save to %ProgramFiles%\maemo\flasher-3.5\ (default installation path of Flasher)
* Fully charge the battery.
* Unplug charger and switch off the device.
* Open the Command Prompt by going to Start then Run (or Windows Logo key + R) and type cmd then press Enter.
* Change directory to the flasher's program path (TIP: Use the TAB key to auto-complete the commands and file-names)

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

* Connect the USB cable while pressing 'u' key on the N900
* Run the following command:

flasher-3.5.exe -F RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin -f -R

Remember to replace the RX-51_2009SE_1.2009.42-11_PR_COMBINED_MR0_ARM.bin with the firmware you wish to update with.

You can sorten the filename of the *.bin file to make it easier also.

The update will take about 3 minutes after which the N900 will reboot and display the Welcome screen with Regional settings.

This one, and yes the back one. I dont know what to do now...hmmmm...

Hey, I finally got it to work, for some reason I had to hold done the power button ("U") in order for it to stay in "Flashing mode" THANK YOU SO MUCH!

HELP!!!!!!! My device doesn´t start in flashing mode by pressing "u"...

I see only a dark "nokia" and it vibrate sometimes.... nothing more

That sounds like it's stuck in the reboot cycle - this seems to happen if the battery gets very low. The only solution I've seen to this is to charge the battery externally (either in another phone which uses the same battery, or in an external charger).

Hmmm my old 5800MX have the same battery but my girlfriend have it and she isn´t at home.
So I´ll try it later when she is at home. I hope that the N900 start in the flashing mode then.

Damn I´ve now the battery from my old 5800MX.
I connected the N900 with the PC by holding the "u"key. In the screen is a usb icon but the flasher don´t start to flash...
It is still say "Suitable USB device not found, waiting."

What do I wrong?

\\edit

IT WORKS but only on the computer (Win XP x86) of my girlfriend.
On my computer (Win 7 x64) the flashing doesn´t work.

What OS are you using? You may have better luck using a bootable Linux CD and flashing it from there.
