Hard reset : Turn off your phone, press and hold Vol-, the home key, and the power for 8 seconds.
If you don't have stock jb backed up you can probably use jb cwm backup from http://forum.xda-developers.com/showthread.php?t=2136204

Then try enter in lelus fastboot mode, ad then flash x-loader, uloader, boot.img and recovery.img from stock rom for your device type model. Then repeat steps 1 and 2
Where can I find the lelus script?

Sorry for reviving such an old thread, but oh well...
Your procedure doesn't seem to work with my device. Just to make sure we are using the same driver packages, can you post a link to the fastboot driver you have successfully used?
My L9 is always showing this "partition doesn't exist" error message, no matter what I try. Lelus's script seems to do the job and the phone is detected as a fastboot device, and can even be detected in LG Flash Tool (using a 910K cable), but flashing will stop after a little over 2 minutes, because the phone disconnects. During all of my attempts, the screen stays black.
Any hint?

Can you boot into recovery? We now have a custom recovery for locked bootloaders (and CM roms). If you can get into recovery, I would try some adb commands to mount the partitions.
No, no recovery. Just to make sure that I'm not doing it wrong, what is the key combination to boot to recovery?
I have also tried:
Code:
fastboot boot some_recovery_image.img
It says ok, but the phone just hangs at the black screen and becomes undetectable as a fastboot device, until I pull the battery. So, unless the some_recovery_image.img is unsuitable for my P760 (which may be!), there is something seriously wrong I think.
Or maybe I can try the same command with the custom recovery for bootloader locked phones... Where can I find it?

Your EMMC partition is wiped or fried... you really need a JTAG service or a Box like octopus because your L9 is Hard-bricked...
Thanks for your opinion. Yet, I still want to hear from others.
I'm running into more and more problems with the L9 as their me grows.
-Fastboot doesn't work under Windows 8.1 and 10, but under the now obsolete(for me) Windows 7, unlike my other devices, which are fine with Win 10.
-ADB seems to work, but requiring the device to be still able to boot.
-I always boot to recovery from within Android as long as the L9 ain't bricked. After a failed rom install, during which the sd card failed(could no longer write or be formatted afterwards, the last time stamps of files and folders were set during the failed install) I discovered a problem with TWRP(Artas182x's and Edwin's), which may have been present since a long time: Trying to invoke TWRP via keypress will brick the device!
So, if my P760 no longer boots, there's only download mode available, sort of the final line of defense.
-There's sort of a trick if even download mode fails: After a failed attempt unplug phone, force switch-off, if the phone is in brick state. Then switch on, force switch-off again, and only then attempt download mode again. And have patience while holding down the vol button, it might take up to 20 seconds for the phone to switch itself on into download mode. (A single forced powerdown will cause Fastboot NOT to work the next time)
But I'm absolutely clueless about the recovery issue, for now TWRP is semi-working, can only be accessed via Android, as long as the phone is fully working.
W/o Fastboot, I now have flashed stock rom several times and rooted it with Kingo rooter just to be able to run Flashify to install TWRP. If Flashify is the culprit for the TWRP issues, I could need a recommendation for a better working app.

Tried OMAP flasher ? It needs memory configuration file in order to work with our device
No, I didn't. I have sold the phone for spares.
Inviato dal mio LG-D855 utilizzando Tapatalk
I never needed the OMAP drivers and tools. As they are ancient, they will probably make even more problems with newer Windows versions.
I could by no means invoke Fastboot on this device with Windows 8.1 and 10, Seven worked. So you had to go for Download Mode instead to recover to stock rom, then root with the Kingo tool, then install TWRP via Rashr or Flashify, the most time consuming way to recover from the frequent bricks.
And the LG Flash Tool 2014 always needed several attempts to get the job done. The latest official recovery tool from LG works in D/L Mode, but will always download the rom image anew.
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.

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!!!!!
I tired to restart phone after noticing that WI-FI isn't working (maybe my internet was laggy, don't know). After restarting phone was stuck on LG logo, i tried many times but again LG logo.
Then i started recovery, and wanted to flash some new ROM. But my CWM won't recoginze my SD card (to add, i wasnt using SD card with this phone). I tried other SD but problem stays. I google it and found out that maybe CWM needs update?
Version of CWM Recovery v6.0.3.1
This shows up when recovery starts..
E:Cant mount / cache/recovery/command
E:Cant mount / cache/recovery/log
E:Cant open / cache/recovery /log
E:Cant mount / cache/recovery/last_log
E:Cant open / cache/recovery/last_log
How to unbrick phone now?
Unfortunatly don't know what ROM was flashed before, or is bootloader unlocked or not. (coming from LG 3D, LG l9 was present. LG 3d methods for flashing is diffrent, so im little confused how to start anything now)
To add that phone now cannot turn on without charger pluged in. Powering on was OK in first few time...
First and important question. Did you unlock your booloader? If yes, you can install cutom roms. If not, you can't install custom roms.
Did you also try to enter SV mode?
1. Power off phone
2. Press and hold volume up
3. Connect phone by usb to PC
4. Wait few sec
5. SV mode should appear.
When you are in SV mode, you can restore stock rom by official LG program.

I started S/W upgrade, and in upper corner it says Bootloader Status: unlocked. So bootloader is unlocked for sure then..
If i manage to update CWM will that solve my problem with SD card? After that just to flash ZIP from recovery?
O something else?

Thanks, now really noob question..
I googled how to update recovery on L9, and found methods with installing some APK, but as i cannot start system how to flash then?
There is 2 ways to install new recovery.
You can flash .zip in old recovery, reset phone and you will have new recovery.
You can also flash new recovery by fastboot. You need to have .img recovery.
Can you reset to fastboot in recovery options?

What next.. S/W mode says Bootloader unlocked, and before all this phone was using JB..
I still didn't succeded to recover my phone.
My computer simply cannot see my phone, i tried all tools that were avalible. On 3% to 7% (on updating), just says that phone is not connected.
Strange thing is that i managed to flash V20H_00.kdz two times. Every single time i do the same but only that 2 times flash was successful. One time was with "offline method" and then with "LG flashtool 2014", after that flashing i got dead android with red triangle both times.
Then i wanted to flash v20c_00.kdz , but cannot pass 3% to 7% on flashing AGAIN. I'm frustrated !
I tried to flash on other computer but again, phone is not recognisable.
What to do now?
Can i flash ROM with fastboot ?
UPDATE.
I started upgrade recovery with LGMobile support tool, and finished flashing. But AGAIN i got dead android with red triangle!
Now what to try!?
Update
I even tried to flash ROM on WIN XP, but nothing. Again proces stops on 3% (then quckly) jump to 7%. And thats it.
Strange thing that when i start UPGRADE RECOVERY on Official LG TOOL (i think thats official), program download 500mb+ KDZ and process is successful, but i get Dead Android with red triangle..
Anyone have any advice? What to try?
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:

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.
Yesterday I tried to flash a a new rom on my Xperia Z2 (unlocked bootloader).
From TWRP I did an advanced wipe and selected basically everything except my mircoSD (because it has the new files).
After a long time of waiting I tried to flash the ZIP file and it gave me an error. I thought this had to do with the wipe so I decided to reboot my phone.
As you can imagine, it got stuck on the Sony logo (because system would be empty).
From this moment I couldn't do anything with my phone, except from the tool Emma.
I now have some clean installation of Sony their Android 6.0.1 for the Z2 (23.5.A.0.570) but Im unable to flash TWRP through fastboot.
The command adb devices shows my phone, fastboot devices gives an empty response.
When I restart to the bootloader from adb and try to flash TWRP I get the message "< waiting for device >".
I tried on three different PCs including a clean install of Windows with all kind of different drivers, yet I cant get fastboot to work.
Am I stuck with this unrooted version of Android now or do you guys have any suggestions for me?
Thanks in advance!

As I said I've tried all kind of different drivers (Android tools, Sony drivers and flahstool drivers). So for me it's hard to tell what I'm doing wrong.
My computer notices the phone (if I hold volume up and attach the charger), it just doesn't show up under fastboot devices.

Okay, apparently it was because of the driver signature stuff in Windows 10.. The fastboot command now works fine!
Next problem occurred though, flashed the newest TWRP recovery but as soon as I enter "adb reboot recovery" my phone just normally boots again..
Why do things never work out the right way for me as they are intended..

Manually boot into recovery by booting up your device normally and when you see a violet LED, press vol+.
