GTA02 NAND problem and devirginator

[Leonardo Guardati]

AHi,

   I have a bricked GTA02v7 and the Debug Board v3.

I left it for quite some time and now I would like to
revive it.

I think there is a problem with the NAND Bad Block Table.

But also could be I have flashed something wrong in the past.

Anyway.

The phone boots, but the display never activates, and the dfu-utils
doesn't see the attached gta02.

Using the debug board I can see the serial console spitting bootloaders
messages.

The NOR bootloader (I'm quite sure I never flashed it, so it should be
the same shipped with the phone) says:

      Uncompressing Linux... done, booting the kernel.

The "mtdparts variable not set, see 'help mtdparts'" lines appear after
some seconds.

Then the NAND flash bootloader starts; it is the Qi botloader.

Looks like it tries to boot, load the linux kernel and then....brick.


I've searched the wiki and found the "devirginator".

I managed to upload a uboot image (and the environment) on RAM using openocd
and run it...but it gives a strange error about usb (maybe is the reason why
dfu-util doesn't see it). Here what the uboot from RAM says:

Also I cannot get to the uboot prompt (the NOR one or the RAM one), where I would issue the
various "nand" commands to erase nand and recreate the bad block table.

from wiki this should be the sequence:

nand bad
nand scrub
nand createbbt
dynpart
dynenv set u-boot_env
saveenv



Can anybody help me? I don't know how to get to the prompt of uboot.
Or maybe there is another solution to clear the nand and recreate
the bbt.


Greetings.
