Help Me Please!
My phone CAN'T boot up!
Not happen when i press Power button
My computer cant find device (OMAP44...) when i connect with USB cab
I Can't Install driver for it
My phone is realy died
To use OMAP driver (with a bricked phone), you must remove your battery then plug your phone (without battery) to your computer : you should see the OMAP device appear and disappear in a loop. Be fast and install the driver while it's here.

When I plug my phone (without battery)
Only the sound (connect and disconnect) without OMAP device
Strange, if Windows make the connection sound, then, it should appear (and desappear, and reappear...). Maybe you should try on another Windows installation (on another computer).
Apparently, if you flash official LG firmware with a locked bootloader you won't be able to brick your phone. So there will be some way to recover your phone. Can you boot into SW Upgrade mode?

I can boot into SW mode,but my phone SWmode can't use KDZ_FW_UPD_EN,If I want to change the rom i should boot to os and set the LG Software mode to change my rom
Have you tried the complete offline flashing process from the beginning to unbrick your phone? If the computer still recognises your phone in SW Upgrade mode, you will be able to unbrick it
If you were on JB before bricking your phone (and obviously, you were : "I'm using Vietnam V20a Rom"), the offline KDZ flash method doesn't work, you must apply the online KDZ flash method.

i too got such problem.
while holding down back +Vol down connect your phone to pc .It will enter into emergency mode.Then your Computer might detect it.
Can anyone of u help me ???? My phone is still stuck with Fastboot mode
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.
Hope this is of some help to you.
Finally, Recovered my phone by flashing KDZ through Emergency mode.. No other method worked..

I had the same worries coz my pc did not detect my device at all..
I was trying to get pass the Fastboot mode.. But in the cmd when i tried to erase and re-install recovery it said waiting for device.. Luckily and finally after many tries i could enter emergency mode. Only then the phone got detected but fastboot didnot work there.. The Only way out was to Do the KDZ flash. I flashed the indian GB V20b and did a hard reset now. Flashed recovery and for now have left it with the stock rom..
I wonder now this problem arises due to custom roms.

Is the fastboot mode the so called "Brick-ing" of mobile device.?

this problem was cuz didn't perform the steps carefully.
This can called bricking but not fully . As it can be recovered.
Bricking is when your phone is as useless as a brick.
I've been trying to flash my p768 for JB V20A VIETNAM. i used V20A TELCEL, MEXICO Before this flashing.
So I started flashing the KDZ file, followed all the necessary steps and finally when the process is at 15 percent, flashing stopped saying there is a problem with communication between cell phone and pc.
So i did the workoaround, remove the usb cable and wait for at least 10 secs and reconnect, then waited for all the drivers to install. After restarting the whole process it got stack still at 15 percent. Now I cannot get out of Software update mode even if I remove the battery and start the device again.
also i use Following method. and it dosent work. and at 15 percent, flashing stopped saying there is a problem with communication between cell phone and pc Again.
method:If you were on JB, the phone won't be recognized on "S/W Update" screen by the offline method. You must use the online method :
- Remove the lines you put in your "hosts" file ("127.0.0.1 csmg.lgmobile.com" and "127.0.0.1 csmgdl.lgmobile.com") then reboot your computer
- Connect your phone (on the "S/W Update" mode)
- Directly start "B2CAppSetup.exe" : it should detect your phone
- Click on "Customer Support" then "Recovery Phone" (see screenshot on http://forum.xda-developers.com/show....php?t=2217710)
- Wait and pray... It can be long because it downloads the last KDZ file from official LG servers.
plz help meeee

The LG Update Tool can install latest drivers for you: did you properly install them ? If your phone can start in "S/W Update" mode, the online unbricking method should work, that's why I think you have a driver issue. Did you also try on another computer with another Windows version ? (the most "driver friendly" version would be a Windows XP at least on SP2).

you need to install fastboot drivers twice, once before you run the omap4fastboot and again after running it when you see that mirrored fastboot text
So I recently wanted to load a custom rom on my p769.
Unfortunately, I tried to flash a rom without actually having the bootloader unlocked (thought i did?)
Now i'm forever stuck at the "LG Security Error" screen.
I can't seem to do anything else! :'(
The only other mode I can boot into is S/W update screen (holding volume up and plugging in usb cable).
I tried to get to another mode I read about (vol up + vol down then plug usb cable for "download" mode, to no avail)
Anyway, once I do get it into sw update mode, I can't seem to do anything either way, when i try to list adb devices, none are listed, when i try to use lg mobile tool, it never connects, when i try to use kdz offline update tool, it doesn't see the phone, it just keeps trying to connect, the log freaks out at "_IsConnectedPhone Call", and just keeps trying to "connect" to phone but can't
Am I totally screwed here?
What can I do? Any help appreciated!

but, what am i supposed to do here?
i see the 2 omap devices listed on my device manager
whenever i try to run the kdz offline flash tool (if i'm using the right one), it still doesn't detect the phone as connected, doesn't even try, just errors and tells me to connect to usb port and restart or exit
what am i supposed to do once i'm in fastboot recovery for my phone?
should i comment out the 2 listings i added to the hosts file? should i NOT be running shttps app? which kdz offline flash tool should i be using? (currently trying: UpTestEX_mod2_marwin.exe)

You should run start.bat and select flash ICS u-boot/x-loader for P769
When it finish, reboot you phone to S/W update mode and try to use UpTestEX_mod2_marwin.exe to flash your P769 kdz again to restore your phone.
Maybe I miss something about P769 model, please search in FAQ forum many people have this issue, and most of them have fixed it.

2.run lelus script at the same time hold vol+ button once the script shows the OMAP device close the script and immediately put the battery back in .The LG phone will boot into S/W mode !
Make sure you write down your imei or serial number AND make sure battery is fully charged . then
Now simply use the LG software tool or the KDZ offline flasher look around the forum for how to guides

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?

Then you need a Technician with a Octopus Box to repair your partition table...

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.

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!!!!!
