wierd fastboot mode started udc_start() - Optimus One, P500, V Q&A, Help & Troubleshooting

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://forum.xda-developers.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?

Try TO boot recovery

This worked for me too. Try it! Good luck!

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*

Hey, i have a same problem, nothing work, only:
fastboot mode started
udc.start()
-- suspend --
-- suspend --
-- suspend --
the same what you have... is here is anybody who can fix it?
oh, by the way i have LG P350, not P500... but problem is the same...

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.

Same problem with lg p350
I have the same problem with my LG P350.
but my phone doesn't even boot to emergency mode.
Every time i connect it to usb it says

Did anyone of you guys try this tutorial first?
http://forum.xda-developers.com/showthread.php?t=1088046
It had worked for me.

here's the solution..
disconnect everything(usb, charger etc)
u need to remove battery of ur cell phone
then hold both volume keys..(dont touch power or call or nay other key.)
then connect usb to ur pc.. and while holding volume keys(both) connect other end of usb to cell phone and ur cell will start in emergency mode..
.
then download
KDZ_FW_UPD_EN u will find it on net just google it..
then download
any kdz software update of anything ics,2.3 anything..
then install and use kdz_fw_upd
and select type : 3GQCT
PHONE MODE : EMERGENCY
AND give the path where u downloaded kdz file
then just click launch software update and ur done..
id any problem mail me on..
[email protected]..
i will reply in 3 days...

For all u'r problems with fastboot,go and download this AndroidFlashRecovery_0.0.1.2_D,by insert the recovery file for your phone
It will erase fastboot&stuff,the will restart in same fastboot,but u wiil stop the phone ,and run recovery mode,then instal a new flash zip file
THIS WORKED FOR ME

Reinstall lg drivers( the ones you install before root)

if you are still in emergency mode, just go into kdz updater, and put the settings at 3GQCT and the State as emergency. then just launch software update. And btw if you wouldve stayed on windows 7 it wouldve been okay, ive used kdz updater about 7 times already and each time owrked.
For in depth guide, idk if you already read this but heres the link

I will do nothing for you but to suggest you that never ever flash a gb rom via kdz (v20*) it will lead ur phone to brick.. always flash v10e rom via kdz rather then other one.........

You had to DISABLE lge Modem, as that causes soft bricking , like you have now.
GO into my signatures link and look up how to flash kdz properly, with all the links attached, as well as how to get out of emergency mode. My guide should just be made sticky, as it has the compilation of all the kdz, emergency procedures, rooting guides into one, as ive lost count how many times I had to tell someone how to do the above things.
Go to emergency mode flash recovery using lgmdp and install any custom rom.this is better then kdz.

you cant get into recovery when its in emergency mode, emergency mode = bootloader, which is before recovery.
Lgmdp is not better then KDZ, dont talk s***, just because its your opinion.
Id the OP is not sure, use google and research for him/herself, but kdz can be used to get out of emergency mode, I have a link to the thread in my sig, for that purpose, its very easy, but dont forget to plug ur phone into another USB port, or re-install your LG drivers and disable LGE modem, as that was most likely the original cause of your problem.

just stuckup in LG logo.. pls help
Ok don't panic this is software related just make shure u install drivers and it doesn't have to show the Korean letter in download sometimes it doesn't just use LG support tool ....but importantly install omap drivers and LG drivers
Sent from my LG-P920 using xda premium
I had the same when rooting the phone, the first thing I did was to uninstall every driver, software I had related to lg. Then visit the official website and download the support tool they had, make sure is the latest one.
When installing the support tool, notice if the program also installs the drivers for the phone.
I also took off the battery of the phone while it was on, I'm pretty sure it didst do anything but just in case.
Turn on the phone in download mode and the tool should be able to recognize it.
PS. Sorry for my English

The following thread is only a few posts long. Read them. Do exactly as the OP states and what is additionally stated in post #3.
Here's the thread. Only thing different you will do is use your KDZ file instead of the one mentioned. This setup just unbricked two P506's for me. They have been bricks for about 2 years. Only booted to Emergency Mode. Now both of them are fully functional again.

no sign of any animation? LG logo for a split second? remove battery and connect charger directly if it shows any sign at all. i think the mobile still can be recovered using JTAG. many had fixed their mobiles using jtags.

Hard brick device!! Last option : remove battery, wait for 30 sec and then insert usb data cable (pc connected), at the same time pressing vol up+back button. See if it work
Edit:
One more option: Open your device back panel by using screw driver. On the device board, just remove the battery and reinsert. check this too if it Hard Reset your device. Best of luck
