Im on CM10
Hello,
If you have CWM Recovery, maybe you can try to flash a stock ROM using it:
http://forum.xda-developers.com/showthread.php?t=2136204
The other method would be the unbricking process through LG Update Tool. First, you can try the offline method (if it recognize your phone when it is in "S/W Update" mode). Then if the offline method fails, the online method will probably succeed (but it could be quite long because it download the last ROM from official LG servers).
Good luck.
Hey Guys!
I'm currently having an issue i would like to share:
I'm trying to fix my brother's phone, is an LG P768. He tried to root it (first time ever) and apparently he flashed wrong Xloader and Uboot. The phone still works but i am unable to access SW Download mode or Fastboot (Required for Flash stock rom again). I've read many threads where you can flash those files again but the same issue I need to flash them via Fastboot or SW Download mode. obviously i need to install the drivers in my computer to do this procedure but there is no way to install them if my phone doesn't boot properly into those modes.
Model: LG p768
KDZ File: v20a_00
4.1.2 Stock Rom
Hopefully someone can help me.
thanks
Hi...
i want to know if is possible unbrick this phone. I've already tried:
- KDZ Flash (LG Flash Tool 2014), can't downlaod the lastest KDZ firmware for it because the page doesn't exist anymore, so i just dowloaded a previous version. Then when it start the upgrade procedure an error ocurred: "Upgrade stop due to an error"
- With the LG original mobile tool.
P.S. My phone was rooted before the brick.
Thanks!

Have you downloaded the lg mobile united drivers, because without it the flash tool will not flash the firmware You can download the drivers from the following url
http://www.mediafire.com/download/g31hbcdmh14io89/LGUnitedMobileDriver_S50MAN311AP22_ML_WHQL_Ver_3.11.3.exe
And if you have missed some step you can see from the following url

Hi! I've managed to brick my device (d610ar) badly, i think
the device doesn't boot normally (message "Secure booting error! Cause: boot certification verify.", and i am stuck there), can't charge it with the wall charger, and the only thing that works is download mode; but flashing a kdz with LG FlashTool (the way i went back to stock a few times) says flashing and at 2% (or 3% sometimes) it says that doesn't find the device, that i have pull out the battery to reconnect my device again and when i do that it does the same thing on a loop, asking to do it again later..
the funny thing is that it appears on device manager on windows, on com port 11 for example, but the FlashTool doesn't recognize it..
so, i can't flash any kdz and doesn't boot.. i've read around here in xda to enter fastboot to fix it, but.. can this device enter fastboot? i couldn't do it, tried adb too and couldn't make the device visible..
i, before this happened, had multirom installed, rebooted to recovery and deleted secondary roms to install in primary rom cm12.1.. there started to happen strange things when rebooted normally to configure it..
after a while trying to boot found around here in xda too that i could enter twrp recovery via hardware keys to reinstall again, so got into it and installed a flashable zip to come back to stock KitKat directly, that have worked for me before..
after that rebooted and i can't do anything else than download mode..
i kinda figured that the problem must be that multirom injected the boot sector after installing the stock flashable zip, and when i did that restored the stock aboot and abootb (these, modified carefully, allowed us to unlock bootloader and flash recoveries, etc, etc.. ; by the way, many thanks to the devs that discovered it and made the guides!)..
now i have read the instructions for flash via fastboot the stock boot.img and so pass the security verification, but i can't enter it..
so, what do you think that could be the next step? or is it really hard bricked and i should forget about it? i'm really hoping to recover it but i don't know what else to do..
sorry for the bad english, not my primary language
thanks for reading and i am hoping to hear some suggestions!
He is not hard bricked you need to flash stock boot and reunlock bootloader if you have custom recovery still installed, but go first with the eazy way search xda about lg flash tool stuck at 2% there some guides to help you get kdz flashed
Thank you very much!

Thank you very much! You made me realize why wasn't working..
Because of you, i started to search threads related with the "flashtool stuck at 2%" and one of the things to look at was a txt file to see what was the problem.. there i found out that the lg FlashTool recognized my device as LGD618..
That's when i realized that i must've messed up when i flashed a lollipop flashable zip for the D618(a while ago), "converting" my cellphone on that model.. so when i connected on download mode and put the LGD610 kdz the comparison of cellphone model and binary model didn't match..
Solution was to flash LGD618 kdz, boot up normally, install towelroot, install supersu, edit a line on build.prop
from persist.multisim.config=dsds to persist.multisim.config=none
rebooted and that's it.. everything works perfectly now! i won't be doing stuff to it for a while
probably will stay stock like that, because now i will be using an OnePlus One in a few days and the G2 mini will be used by my mother, i think..
Thanks again! You saved my device for being bricked forever
i glad i could helped you :good:
I tried installing kitkat having installed lollipop and did not work, also I tried installing lollipop and nothing. Well I think this update lollipop are adding some kind of lock to disallow downgrade or upgrade by KDZ. I try other methods, unlocking bootloader, and install a aboot.img, bricked my phone. I recommend that you do not attempt to unlock the bootloader and install any system image that is not official, or may end up with a dead device.

Ignore all errors. Just start the flashing process and DO NOT touch anything.
If you just want to have rooted KK, follow this guide. No need to downgrade to JB if you want root. Just make sure you flash the latest twrp after you flash the pre-rooted kdz.
Second problem
