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

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!!!!!
Hi,
I earlier had cyanogen mode installed in my lg l9 P765. I also had clockwork mode recovery installed for doing the same. Recently i saw a post to flash android lolipop to my phone by artas in http://artas182x.tk/android-projects/android-5-0-lg-optimus-l9-aosp/. I installed TWRP . But since i couldnt proceed to enter TWRP recovery, i just tried using `reboot recovery` via terminal. This got my phone bricked as i cannot access my device using ADB or Fastboot. All i see when restarting is the LG logo. And all i can access is the software upgrade mode. Since i had came across such a situation earlier and overcame it using the method to flash new rom offline, i followed the guide given in forum.xda-developers.com/showthread.php?t=2085344 by @cmahendra. But i always got the process stopping at 15% telling that the phone and usb arent connected. I couldnt download any of the roms listed in the same page as the links seems broken. Is there a possible way to get out of this issue?
Thanks
HI. Do you already solved the problem?, If not. Check you have correctly installed the drivers of L9 and using the "LG Flash Tool" ( http://forum.xda-developers.com/showthread.php?t=2797190 ) Install your KDZ... if it shows any errors during the process, allowed to continue in the background, do not close the error window.
Hi!
I'm so stupid. I wanted to install cm12.1. So I rooted phone, unlocked BL. Then, I had first problem - when executing adb oem-unlock BL has unlocked and phone go to fastboot. But my comp couldn't recognize it (heard plugging in and out sound repeatedly). And here comes my "stupidity". I installed flashify and flashed CWM by it, got to CWM, installed cm12.1 zip. Of course wiped all data. Because I didn't flashed boot.img cm12.1 was freezing on fist setting up screen (nothing was working, just power button - pushing 10s turned off phone).
I wanted to flash boot.img by fastboot. But I still had problems with drivers(omap4boot didn't work). So I tried to recovery system by LG Mobile Support Tool. Everything got fine, but then phone stuck on the LG logo.
S/W Uprgade mode works of course, but I can't get to recovery now.
I'm using Windows 8.1
Any ideas?
Edit.
Ok, so I tried to install omap again. I did it, but the phone is still repeatedly conecting and disconnecting and in device manager I cought omap4430 driver whith waring mark for a while. Any ideas now?
Is it the non-animated LG logo?
This should work:
http://forum.xda-developers.com/showthread.php?t=2748384
The download links for the firmware are probably not up to date. Use this to download: http://forum.xda-developers.com/showthread.php?t=2287573
If your phone still goes beyond the non-animated logo, there might be easier solutions.
It was after animation.
Anyway, I have finally solved this problem by installing new system using Bride's solution with full wipe.
