Hello,

I'm new here, some weeks ago I was trying to uninstall NITDroid from my N900's internal memory that I had installed from nitroid-installer (a maemo script). It made my device to use "Nokia N900 - Multiboot" for selecting the OS, once I removed NITDroid, it seems to have deleted my maemo OS too!... just like a "rm -rf /" .

Now, when I boot my phone it gives me the multiboot menu, if I choose NITDroid it panics with "Guru meditation" and if i choose Maemo it starts a nasty reboot loop. Trying to enter the phone in recovery mode ('u' key pressed) doesn't work and the battery isn't charging from the phone. In GNU\Linux when I connect the device it isn't being recognized as a valid USB, dmesg says:

"device not accepting address 6, error -71"

In Windows 7 64-bit it says:

"The USB has been disabled due malfunction" or something like that.

Obviously, the "flasher-3.5 (windows/linux)" is still "waiting for a suitable device"... All the posts named as "repairing a bricked N900" or similar aren't working for me.

My question is: do I have any chance to repair my phone?, or does it need to be thrown to the trash can?

In my country(chile) there's no tech support for my device, so you are the only resource I have.

The problem is really hard to explain, sorry.

Thanks.

about removing nitdroid

as you already reached multiboot menu, your rootfs seems to be intact, as multiboot is in /sbin/multiboot, if the rootfs was cleared you wouldn't get to it anyway.

so most probably you are just missing the correct kernel, have you actually tried pressing 0 in multiboot menu ? that should attempt to boot maemo using the original kernel.

if it fails, you many be missing the kernel image, so flash the pr1.3 kernel only and try to boot again (still press 0 in multiboot menu).

first, force your n900 into flashing mode, take n900's battery out, connect the n900 to pc via usb with the battery out, press and hold "u" on the n900's keypad, insert the battery into the n900 while still holding "u", after you see the usb icon on the n900's screen release the "u" key.

then flash the kernel only by:

flasher-3.5 -F <firmware-image> --flash-only=kernel -f -R

and try to boot, in the multiboot menu press 0, it should boot maemo, if it doesn't then well, try again but this time, unpack the fiasco image using:

flasher-3.5 -u <firmware-image>

then as posted originally by MohammadAG in http://talk.maemo.org/showpost.php?p=906345&postcount=8 :

flasher-3.5 -k zImage -l --boot="init=/sbin/preinit_orig ubi.mtd=rootfs root=ubi0:rootfs rootfstype=ubifs rootflags=bulk_read,no_chk_data_crc rw console=ttyMTD,log console=tty0 snd-soc-rx51.hp_lim=42 snd-soc-tlv320aic3x.hp_dac_lim=6"

maemo should boot, as above command will completely override multiboot, when you get to maemo, remove multiboot..

if all else fails and you resort to flashing..

the rootfs (meaning fiasco image) should always be flashed first if your n900 doesn't start at all

after flashing the fiasco image, you may then flash the emmc image.

despite written in a lot of places otherwise, and many people insist on it being that way, the rootfs should be flashed first, as flashing the emmc, requires the n900 to boot into flashing mode, you can get more info on this if you read the original /sbin/preinit shipped in pr1.3.

Hi, thanks!... but what happen if I can't start my phone into recovery mode?, my device isn't being recognized, so i'm not able to flash the phone... when I connect it to my notebook while pressing 'u' key, the phone doesn't show the usb icon, it starts a reboot loop showing the kernel processing.

I'll try to run the flasher on windows XP to see if it runs there.

Thank you.

ok try windows XP just please try an x32 version ..

also, did you takeout the battery, connect the n900 to PC, press and hold "u" then insert the battery, after that release "u" ?

if that's the case I will ask you to try flashing on a different PC or different usb port at least, and using a different usb cable. just to be sure
