I was away for the weekend and randomly my N900 decided it wanted to go into a continuous reboot loop which I cant seem to fix! I've tried (warm) flashing it to no avail. I wondered if someone might be able to tell me how totally wipe it, back to day one standard. I cant seem to find instructions anywhere that my noob brain can understand!

Cheers!!

First you will need to do a eMMC flash using Flasher 3.5, then do a OS flash later using Flasher 3.5.

Follow Wiki for more information on how to do the eMMC flash. If you don't flash eMMC then the Phone will be stuck in eternity loop.

Why? because there are packages stuck inside the install partition and causing it to clash with the OS partition when it is trying to boot up.

Hope this help

There are different steps to use, depending on what operating system you have running on your computer.

Windows: Windows users can update their Nokia N900 using Nokia Software Update tool. You can use this walkthrough to install and run NSU under Windows 7, too. Be sure to backup any critical information before applying the update, as it will reset your device to factory settings. The internal device memory will be cleared, but your 32GB internal memory card will not be.

Linux: Linux users can use the Flasher to update their firmware. Download the flasher here, and the N900 firmware image here. To start flashing, turn the N900 off, then connect the USB cable (with the device still powered off). Open a terminal and run ‘sudo ./flasher-3.5 -F <firmware image filename> -f -R‘ and enter your administrator password. You’ll get a message that a suitable USB device isn’t found, so you’ll now need to press the power button to turn your N900 on. Once it’s on, it will start flashing, and then it will reboot. When you see the normal desktop, you can disconnect your N900.

Mac OS X: Follow the same steps as for Linux users, except you’ll need to download the 770Flasher application. As with Linux, you’ll want to connect your N900 (powered down) via USB cable, then run the 770Flasher and drag the firmware image that you downloaded (ends with .bin) over to the 770Flasher. It will tell you a suitable USB device wasn’t found, and that’s when you press the power button to turn the device on. It should then begin flashing your N900, and again, when you see the normal desktop on the device, it’s safe to disconnect.

Hi there,
This is my first post in Maemo but for a problem
My N900 rebooting continuously.. I have done the firmware and eMMC updates to fix this problem but all in vain Totally disappointed..When i try to do the firmware update for the second time to go for a chance, by pressing the 'u" key is not showing the USB symbol at the top right corner and also my PC (Windows) is not detecting the drive... I really don't know what to do..Please guyz please help me out Waiting for your replies to make my N900 live again..
Thank you All..

If your using Windows 7 32 bit, disconnect your internet connections, then flash using this:
flasher-3.5 -F "FIASCO" -f
Then by this:
flasher-3.5 -F "EMMC" -f -R
Be sure to place the 2 .bims in flasger 3.5's directory, and to hold the "u" button while plugging in the usb cable to your N900.
