hello,

one of my friends recently arrived with a tricky problem.
he has an old-ish LG Optimus One that he flashed badly and now is stuck on continous boot loop.
all it displays is:

fastboot mode started
udc.start()

Click to expand...

Click to collapse

however, unlike the problem fixed here: http://xdaforums.com/archive/index.php/t-1088046.html
it does not recognize USB cable:

fastboot mode started
udc.start()
-- suspend --
-- suspend --
-- suspend --

Click to expand...

Click to collapse

it only says suspend even after multiple plug-ins and no driver pops up on my PC or his...

i call it permanently bricked:crying:, but i'd like a second opinion?

The udc_start() screen appears for me occasionally when I fail to boot into Clockwork Mod (Seems random)

I simply take out my battery, count to 5, put it back in, and try again - Normally works after 2 or 3 retries *Shrugs*

Simply take out the battery. If your friend is rooted, has a recovery and a working ROM on his sd card, ask him to flash that by booting into recovery

i managed to find the problem:
i've conected to the device via jtag interface and attampted to erase the curent flash. it failed at abut 25%(bad block).
after checks it turned out it has a phisycal problem bloc problem . i've atempted to make a full dump igonrign bad sectors, and now it boots until LG logo.

atleast its loading something now.:laugh: aparently there is no way to fix this exccept for a motherboard replacement.
