Hallo i have a Problem while Restoring my L9 .
I installed Cyanogenmod 10.1 but now i wanted to use stock rom again. So i Used the Recovery Mode of The LG Update tool. At 90% of the recovery Process my LG closes the usb connection to the PC. After that i had a Bootloop of the LG Logo. Now Nothing instead of getting The Phone to S/w -Mode works.After this i tried to get cwm on the phone to install cyanogenmod or something else again but CWM was erased by the recovery mode. All tries to get the phone into fastboot dont work ( there is no LG logo that loades and fastboot dont accept the phone. Can you please help me resolving this problem and get my phone to work again.

What about the offline flashing method? Using a kdz file?
Sent from my LG-P760 using xda app-developers app
I did it I unbricked it with this method :
http://forum.xda-developers.com/showthread.php?t=2119090
So i got it to fastboot and then I flashed CWM with it to my Phone after that i flashed a custom rom via cwm --> Working
Now theres only one question remaining. How can i get a stock rom to the phone if this LG tool dont wirk is there a version for cwm and p760 out ?
I can get into cwm but everything i flash just leads me to a screen with the lg logo. Therefore, I'm trying to fast boot my phone and recover my phone but so far I've only been able to get to s/w upgrade mode and recovery stops at 15% because my computer sense that the phone isn't connected. I've tried running the recovery software in diag mode but it couldn't get past 15%. Can someone please help me?

2 options
Download LG mobile support (B2CAppSetup.exe) and select recover your phone. Your phone must be in S/W update mode and you must remove/comment LG server line in hosts file (for offline flash)
Try to use Lelus fast boot to flash ICS u-boot & x-loader (according to your phone model). And try to offline flash again. JB firmware does not work with offline flash.
Hi all!!
Yesterday i tried to install android 4.4 but the procces didnt succeed, it stuck at. LG boot logo. So i decided to restore my backup in ckockworkmod,it started the process then stopped at the phase "restoring /system" . I waited about a half hour, and because it didnt take the much time before, i took out the battery. I read somewhere that formatting the system partition in cwm could help, so i did that. Then i retried restoring my backup. It stuck at the same phase. Later i downloaded the official kdz, and decided to flash it. I could bring the phone in update mode, but the process stopped at 15% at lg update manager.
At the moment i can get into clockworkmod, but cant restore /system . The update mode is also okay. I dont know that fastboot works or not. I havent tried it yet. Please help me thanks in advance
@trapistasajt
You will need to get fastboot working and use lelus's fastboot script to flash the "u" and "x" loaders for the device and then perform the offline or online flash
http://forum.xda-developers.com/showthread.php?t=2292828
Also as you found out you cannot flash custom roms without ulocking the bootloader first and you cannot use the L9 CWM bootstrap recovery for Locked Bootloaders, too flash custom roms.
try this online flash methode with B2CAppSetup

i had the same probleme and i fixed it .
My bootloader is unlocked. I tried the fast boot method, but it doesnt go further than "Waiting for omap...." . So, i couldnt go into fastboot (probably my fault). Yesterday i sent it to the service. If they notice that my varranty is void (because of the unlocked bl) and send it back, i will try it once more. I would be very thankful if someone could write a noob friendly-fastboot guide. As i read, lots of people are struggling with the same problem. Thanks in advance!!!
You have to use LGMobile Support Tool (Install drivers from it first) Then enter in download mode conecting the phone to pc pressing vol+ and the rest its automatic.

It didnt go further than searching for "omap device", so i couldnt load fast boot, as i said. my phone is still in the service
If they 'll send it back to me, because of unlocked bootloader, i wil try it once more. Any suggestions?

I dont know about fastboot.
LG Mobile support tool let you download the correct drivers. Then connect your phone while u keep pressing vol+ and it enters in SW Upgrade mode. Then just click "additional features" and "upgrade error recovery"

It shows something about firmware ir will restore. Ir will flash the latestbfirmware from original carrier release.
For example i actuallybhave v20L but my original carrier only released v10a. It will restore to v10a
None of them works, other ideas?
This fastboot method worked for me in 5 min, pay close attention to the instructions and it works!

Spent days with LG update tool which if you read the log has no url for files to download.
Good luck!
I got my phone back from the service. They didnt repair it, because my varranty is void. I tried the methods mentioned above.
First, I tried flashing kdz, (with the solution for post-jb problem), but i couldn't get into S/W mode, which was available before the service.
Second, since i couldn't load S/W mode, the LG upgrader wasn't successfull, too
Third, fastboot still not work.
I am sure, that im not the only person with this problem, since it happened during installing @artas182x 's JB 4.4 rom. Please @artas182x or somebody write a noob-friendly guide/suggestion which may help to unbrick my beloved phone. Thanks!!!!!
