Hey folks,
its bricked due to FOTA (I think it stands for: firmware over the air) update. This means the phone downloads a firmware update without computer connection or further PC-Software. Alas it didn't work.
Situation:
Phone starts, displays LG Logo and after that an 'updating firmware' screen for about 1 sec before rebooting and doing it all over again.
What I tried to solve this:
set up a new Win 7 32 bit machine to try to unbrick it. (drivers didn't work correctly on 64 bit) at least the MCCI driver update didn't)
connected the phone with the PC in Emergency Mode (holding VOL_UP + VOL_DOWN + PWR while USB is connected)
downloaded B2CApp (LGSupport Tool) and installed the device drivers for Emergency mode.
disabled the Android(Modem) dirver
downloaded V10D_00.kdz from LG home page
using the phones IMEI and this link:
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=IMEI_NUMBER_GOES_HERE
This gave me this link
http://csmgdl.lgmobile.com/swdata/WDLSW/LGE720/ADEUBK/V10d_00/V10D_00.kdz
I'm German so this seems all right, but I'm no expert​
installed msxml
ran KDZ_FW_UPD_EN and tried CDMA in CS_EMERGENCY Mode
A bunch of magic happend until the phone restarts during the process and is right back where we started, if I put it back to Emergency Mode while KDZ_FW_UPD_EN is still running the process finishes, but to no avail.
The log of this try is attached.
Where I am stuck now:
phone:
runs in Emergency Mode
is recognized by KDZ_FW_UPD_EN as well es LG Support Tool
Flashing via KDZ_FW_UPD_EN finishes
Flashing yields no result.
What else did I try
download V10C_00.kdz, as well as V10A_00.kdz from LG site and tried those with same result as with V10D_00.kdz
tried 3GQCT Type instead of CDMA
Wild guesses by me:
I need a different KDZ_FW_UPD_EN version, maybe different dll. I got it from here somewhre in a LG P500 related topic.
I messed up the driver install or need a different driver
LG hates me personally and planted this whole brick specifically to get to me.
The device really is permanently bricked, so I did all I could and there is nothing more to do? That would be sad, I hope I'm wrong here.
Additional Info:
The phone is not rooted and has never before been flashed. It ran with the same stock firmware since it was unwrapped.
The phone was not interrupted by power-loss during FOTA update.
The [read phone information] tool from KDZ_FW_UDP_EN crashes every time, maybe this tells somebody where things go wrong
Any help is appreciated. Ask for more info, if you need it.
Update - What else did I try:
I got the LG Support Tool to flash the Emergency Recovery all by itself runs till 99% --> reboots --> still stuck in same ol' bootloop
reentering Emergency Mode from the bootloop makes the Emergency Recovery finish with 100%, no error, but still bricked.

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!!!!!
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.
Hi,
I need the LGAS323 firmware kdz file(which i have not found). I've been trying with the MS323 kdz through the LG flash tool but it doesn't work(error).
So this is what happened:
I tried to install CWM recovery after unlocking boot and installing fastboot. So after all that I put the command to start transfering the cwm file and the phone got bricked. Now it doesn't even show up the LG logo. It just power up the screen which people call "purple screen" or black... It vibrates one time whenever I connect it to the PC or push the power button.
This is what I've tried:
I have tried all methods I have found on forums and YouTube. I tried with Linux on the terminal fixing the aboot.img and also on PC with the LG FLASH TOOL and other apps but nothing works. Folks help me with this please. I think the only thing that would fix it is using Jtag or something like that you know the boxes(riff, octocplus...). But without the exact firmware it wouldnt work anyway.
Any expert here?
Thanks.
The phone wont go into download mode! BTW.
