[Resolved] [HOW TO] Unbrick LG Optimus One P500 from fastboot mode started udc_start()..

If you did something like install custom recovery on your lg optimus one and failed, you would get a black screen saying..
fastboot mode started
udc_start()
If this happens...
Relax.. Your phone is not bricked.. There are many ways to fix it... This method of unbricking should be done as a last resort because it erases all your data...
Charge your phone before proceeding even if the backlight is always on while charging..
Things required:
Kdz updater:
http://forum.xda-developers.com/showpost.php?p=8651505&postcount=1
Stock ROM:
http://forum.xda-developers.com/showthread.php?t=865479
USB cable, Windows PC with administrator account,LG united mobile drivers(google for it if you don't find it in the "Add or remove programs" window in the control panel)..
First disable all LGE modems under modems from Windows device manager in the Control Panel..
Make sure you have LG united mobile drivers installed.. Or just google for it..
Then press and hold both the back(return) button and the volume up button and simultaneously connect the USB cable..
The phone should light up and say Emergency mode!! in a green background.. If it goes to Emergency mode, it can be fixed... If it doesn't I'm sorry, search for an other forum or give it to the LG service center...
Now decompress the 7z file you downloaded using WinZip, WinRar etc., install msxml.msi from the uncompressed directory and run KDZ_FW_UPD.exe (With administrator rights by right clicking and selecting run as administrator).
In the dialog box, select Type : 3GQCT and PhoneMode: DIAG, select the kdz file and flash the stock ROM... It would take about 15 minutes.. If the kdz updater crashes, change compatibility mode or restart the computer and phone or do something till it works (Retry retry retry)...
For most of you it would probably say PHONE WAS NOT FOUND!.... If so, then follow all the steps said above, but this time, shake the life out of your phone after connecting the USB till the lines "PHONE WAS NOT FOUND!" stops appearing... If it does appear again retry for endless times or restart the computer or check if any modem drivers are active or try it in an another computer...
From here on, follow any one choice:
Choice 1:
Note: There is a fat chance for this choice to not work and for you to go back to the very first line of this thread...
If you want your phone to have all the data before you bricked it, just disconnect the USB when the phone shows the charge screen as if you are charging the phone while it is switched off.. (This was discovered accidentally by me so try it at your own risk ) After disconnecting try to power on the normal way and it should work and the phone should be like it was never bricked.. If it doesn't boot, retry flashing from the start.. If it starts and all your data is restored root it, install titanium backup and backup all your apps and data and save the contents of sdcard\titaniumbackup to your pc.. Then copy all you want in your sdcard to your pc.. Then redo all the steps without disconnecting till the kdz flasher says FINISHED.. This is because if you disconnect the usb in the middle, only half the rom would be installed which is unstable.. After installing the full rom, root it, and install titanium backup and copy all the copied content back to sdcard\titaniumbackup and restore them using titanium backup.. That's it..
Choice 2:
If you do not want the data and if you need to do a risk-free unbrick, then flash with the kdz updater and wait till it says FINISHED.. That's it..
Now that you know how to unbrick, try installing what bricked your phone again but this time in the correct way... GOOD LUCK...
AND FINALLY.... ONE MORE STEP.... PRESS THE "THANK" BUTTON IF I HELPED YOU IN ANY WAY...

where do you get kdz?

By (has administrator) I meant to run kdz with administrator user account rights..
And for your phone not found problem, did you uninstall everything that I listed? If so then you should shake the phone more vigorously from plugging your phone to usb till the phone is found, seriously. If it is still not found, review if you have followed my instructions without leaving a single one out and retry till you suceed... Best of luck... Any more help.. Ask me.

Ok if you can't run it as an administrator try skipping that step and try connecting your phone without admin till your is found.. Try SHAKING...
If it doesn't work.. Take your phone and equipment to your friends home which has admin rights...try till you suceed because it usually is a painfree process.. You can fix your phone if it goes to emergency mode... Dont worry.. feel free to ask for help...

[Q] Phone bricked after LG update. Tried Cyanogen, still bricked

Hey, so, my LG update never finished, and I followed this guide: http://forum.xda-developers.com/showthread.php?t=1180331
But I do not have XP, and the KDZ program doesn't work on Windows7 (I have both 64 and 32 bit)
So I googled around a bit, managed to get a recovery thing loaded on the phone (ClockworkMod Recovery v3.0.2.4)
Then, I tried installing Cyanogen, which I've heard good things about.
I followed this guide perfectly: http://wiki.cyanogenmod.com/wiki/LG_G2x:_Recovery_and_CyanogenMod
The only thing that didn't match the guide was the result of rebooting the device from the recovery menu.
The phone still shows the:
S/W Upgrade
Please wait
while upgrading...
screen. =\

http://forum.xda-developers.com/showthread.php?t=1180331
once you're on that software update screen, you have to try everything known to man to finish the update. no matter what rom or recovery you flash, it won't get past that screen until you get the update flashed correctly.

it does work on win7,for some. maybe doing a clean install of your os might help. make a backup to dvd or external hard drive first. that way you can just restore after you update. or get a hold of someone with an xp pc. or call lg.

There has to be another way. I hate re-installing OSes. and LG is pretty useless when it comes to fixing things.
I did try installing "XP Mode" but the update failed to install.... and apparently there isn't a version of Virtual PC that can run the XP Mode Hard Disk without having been installed via windows update. =\

if there was "another way" someone would have posted it.
if you absolutely intend on fixing it yourself, you need to try everything possible. if you're looking for an easy way out, not gonna happen. have you tried it on win7? it's worked for some people.

Yeah. I've tried my balls off =(

I've discovered that the KDZ program will unfreeze if I unplug the phone from USB while it's updating. (I waited a few hours to make sure this would be safe).
I'm using Windows XP Professional 64bit.
I get this:
[R&D Test Tools Log File]
02:12:23 : Launching SW update
02:12:23 : Unpacking KDZ

02:12:25 : PHONE WAS NOT FOUND!
02:12:27 : ===FINISHED===
I have to reboot the phone before the KDZ program will do anything other than the above log.
But then KDZ freezes again. and.. the process repeats. So... It seems that there is some connection issue between KDZ, and the Phone in my version of windows.
EDIT:
something else I noticed:
When I plug me phone into the comupeter: it shows
LGE CDMA Composite USB Device : Ready to use
Unidentified Device : ( ) Installing driver software
Unidentified Device : ( ) Installing driver software
could this be part of the problem?
I tried installing the drivers linked to from the thread that claims to fix this issue, but it said that I had newer ones.
That I had version 3.0.2 and that was never than 3.2 =\
EDIT2:
In device manager, the unknown device is this: USB\VID_1004&PID_6000_DIAGInterface
EDIT3:
Somehow one of the unidentified devices identified itsself.
LGE CDMA USB Serial Port (COM3) : Ready to use

I would try XP 32-bit if you can. Crazythunder is right. At this point, you need to either get the KDZ flasher to work, or send your phone to LG.

I tried with two Stock Roms...
Please help me in this....

Basically on a windows machine you download kdz updater and uncompress it as it is a zip file.
Download from here.
This is what I did on an xp laptop.
I had to down load the drivers from the official lg site. when here you enter the code that is on the box the phone came in or under the battery.
Chose the your county and laguage from the drop down box at the top right of the dialogue box. Then from the middle you can choose the drivers. For some reason I had to find the files and click on them to install the driver.
Ok once you decompress kdz updater there are three seperate files to work with. 1. windows enabler. 2. msxml.msi 3.KDZ_FW_UPD.exe
You will also need to download the right file to restore with,You can find it with google.
Please check here the The_ERROR thread wich explains it very well:
[ROMS] Original LG Firmware list.
Install msxml now.
Now you have to boot the phone into rescue mode. On Lg Optimus One turn phone off even if it means taking out the battery.
Press power - volume up - back (this button is next to the home button).
Connect to usb now.Computer found new hardware and installed four drivers.
Then open device manager. Left click my computer - properties - device manager. You need to disable the lg modem driver. Left click on it and disable.
Now launch kdz updater. There will be a drop box on left set to 3gspt or similiar. on the right drop box set to diag. The long box just above the info box with a file at the side lets you browse to find restore file. e.g. V10a.00.kdz.
Double click the button below and let it do it's thing. Took 15min. My phone shut down and came up with an error at the last minute. Anyway I rebooted and all was good.
Everything was the way I left it. Just had to re-root.
My only real problem was getting the kdz installer to see the phone.
After installing the drivers restart pc. If it finishes quickly and just before saying finished it says phone not found try removing all phone related drivers including nokia pc suite and the lg suite and remove and reinstall the drivers.
LITTLE ADVICE :You should use some search and keep your eyes open
Two threads related to this are there on the first page itself.

i need help stuck on emergency mode and computer wont recognize phone it did a at the beginning but when connecting I got partition error table on LGMDP, also got an error on KDZ saying someting with error code 1002 ... please help don't wanna take out the battery cause i'm afraid i would have officially bricked it as in it wouldn't start back up! please willing to try anything at the moment!

Just follow the steps which I mentioned above and everything will be alright.

No, i suggest you do not use kdz updater, it had high chances of bricking your phone.

It once bricked my phone too when I removed battery in emergency mode. But after that I used it many times and it worked flawlessly.
You can definitely use kdz, when you know what are you doing.

Fix for corrupted baseband

This is only for people who have corrupted baseband issues (no signal, ? battery icon, and baseband is listed as unknown); if you are stuck at the s/w upgrade screen, you want another thread.
If you are stuck with a corrupted baseband and are unable to flash a .kdz through the updater, keep reading. I have only tried this on xp, and I have tried it with the kdz software updater and uptext_mod2.
1. Set up your drivers, hold volume down, and plug the phone in.
2. Open your device manager, go to modems, and disable the LGE android modem, leave device manager open
3. Start either KDZ_FW_UPD or UpTestEX_mod2_marwin, load the correct .kdz (v21e_00.01.kdz worked for me) and select cs_emergency, it should say Launching SW Update, then Unpacking KDZ
4. As soon as the next group of lines fills in (starting with KDZ file extracted, ending with Call fn_StartUpgrade, enable the LGE android modem in device manager
5. It will give you several lines with wParam and lParam numbers, and disconnect and reconnect once, then when it is finished, it will show the LG logo. Put your battery back in and boot, it should work, if not, try another .kdz (v21y_00.kdz would not work for me).
I used this to fix my g2x with a corrupted baseband, recorrupted it and uncorrupted it again to verify it works. Thanks to kosh2thamax for the cs_emergency idea,

i tried this but it stopped with this msg "MOD UPtestEX MCF has stopped...." anything i need to do to keep it working? thanks.

Thanks for the reply. From all my problem descriptions, and with picture of the phone still turning on to download mode...
I installed,
LGUP_Install_Ver_1_14_3
LGMobileDriver_WHQL_Ver_4.4.2
LGBridge_Setup
UPPERCUT_1.0.0.0
...and despite changing to different usb c, the phone is not any visible to pc nor lgup or device manager.

The main problem i'm facing now are the errors on download mode.

put this .dll in the common folder, let's see if it happened by chance. https://mega.nz/#!qV9WzQSQ!Z0Zkpm-m3LJ01tLthzfE9puNmYlbsOoZR5N-f2VS_mw extract and rename LGUP_common.dll
if it works, install the latest version of android 8 for your model with lgup not with uppercut, run the lgup exe.

I already placed the common dll for f800k prior to flashing oreo which is the same file and oreo kdz i used to update from nougat.
still, pc isn't making any sound of connection of phone been connected
Also the LGflashtool from the second link i already tried earlier. COM41 is not recognised since the phone doesnt communicate with the ports, so not visible to Device manager

If you remove the battery and put it back, is the phone still the same? The cell phone cannot be turned on, so it is a brick. I will go looking for possible solutions, and consider the possibility of using another PC or try to install updates for your PC if it is not already installed.

When i remove and reinsert and then using the vol- & power button combo the phone is still entering download mode with the Unknown / E / L / RO error

Maybe i'll try another pc and give back reply soonest Thanks

I think I have a similar problem that I solved. I wanted to try to flash the root on 9 android, but it didn’t work, the smartphone stopped showing in download mode and in the device manager, but it was detected in fastboot mode. I'm not sure that I showed the same errors, since the stripes on the screen did not allow me to examine the text. Flash recovery https://androidfilehost.com/?fid=11410932744536982447 through fastboot mode, and in recovery-> format data, flash firmware in zip format from 995 https://forum.xda-developers.com/v20/development/vs995-verizon-lg-v20-stock-oreo-rooted-t3845669. After that, the smartphone was detected in download mode and I reflashed it. (I have f800l)

I guess i'm quiet unlucky now in my own case because i am not rooted and no fastboot stuff.
I'm only able to get to Factory Reset menu using the VOL- and POWER BUTTON and releasing the power button and press again POWER BUTTON once lg logo appears.
Also I'm able to get to a SELECT MENU that contains MA-USB(WIFI) DL, POWER OFF, PHONE INFO, BACK by tapping the VOL- or POWER BUTTON like 6 to 7 times repeatedly while in download mode.
Neither of those helping the situation

yet the value of B kept on decreasing now on B59. May that is for the battery? Unknown BATTERY59
