Welcome
I root phone, unlock the bootloader and everything worked nicely. Unfortunately, after restarting the phone only starts ClockworkMod recovery.
I tried to install a new soft CWM 10 of zip and on the same thing, to restore a copy of the original firmware also does not help, always on the LG logo ClockworkMod recovery starts. Is there any possibility to restore the phone back to life?
P.S. Sorry for my english and thx for help.

Please try offline flash again. If your computer cannot detect phone try to update lg usb driver to latest version, I read about this in some thread. If that don't help try to use LG mobile support tool to recovery your phone.

My bro accidentally clicked on OTA upgrade. I have bootloader unlocked , rooted P765 with cwm 6.0.2. I searched this forum for solutions and got some.Unfortunately none worked for me.
http://forum.xda-developers.com/showthread.php?t=2247371 - this method did not work . my phone also has some issues with USB i guess. Everytime i connect to pc , i get device not detected error. screes attached.
http://forum.xda-developers.com/showpost.php?p=40423549&postcount=2 ----this did not work. same as above.
i also tried with exitrecovery.zip . It ran successfully from CWM but everytime i boot, phone still goes to CWM recovery mode.
exitrecovery has following code
busybox echo -ne "\066" | busybox dd bs=1 seek=4107 count=1 conv=notrunc of=/dev/block/mmcblk0p8
I did trial and error with mmcblk0p till 1-20 with no success.
Here comes the saddest part...I also went to LG service centre. He also couldn't help.That guy told me motherboard is dead due to rooting.
I am sure that my p765 is very much alive.
I can go to Software upgrade mode on my phone, but my pc doesnt recognize it. I have latest LG drivers installed on my system.
NOw i think only way out of this could be a script to flash from CWM. Please help me!!.
I tried flashing other roms like Superlumina,Avatar. Also tried Ubuntu touch with no success. Still goes to CWM.
I am on JB India V20A.
Thanks in advance.

You need to install fastboot drivers: http://forum.xda-developers.com/show....php?t=2119090
Turn off the phone and remove the battery. Download THIS and exctract it to C:/. Open device manager in windows (Rigt click on Computer > Manage > Device manager) and connect your phone without the battery to pc via USB cable.
'This' link is broken... u have the files brother?

I connected my phone in Software upgrade mode. Same error pop up- USB device not recognised.
Selected 'Options' from LG User support tool and clicked 'Update recovery'. Entered my mobiles serial number.
AFter around 3 hours of download, my device is detected on my system!!! I seriously did not do anything on my system.
AFter the download was complete, the update was installed. My P765 is BACK!!!!

I'm a new member to this forum. Need your help.
My P765 got stuck up with CWM recovery after an OTA update. I flashed some custom rom's but still it does end up in CWM recovery only.
Could you please upload the CWM zip to flash the stock recovery. So that I can get to back to my P765.
I have been searching in all the forum. Finally found this to get solution. Thanks in advance

The following will work with all OTA boot loops to recovery. The guide is for p765 but it will work with all variants. If you flashed a custom ROM trying to fix the problem, please restore your stock rom backup. Also, if you still have artas182x locked bootloader recovery (or you removed any system apps), the update will fail, but you will be of the loop
what kdz are you currently on? I made the zip but i need the extracted p765 recovery.img.
If you have the kdz please extract the recovery.img (look at my signature on how to extract it).
i could give you the p760 20b recovery.img but I think it would be best to use the recovery.img of the current kdz you are on (to be on the safe side).
Note: if this doesn't work, you will need to use the unoffical fastboot. So you might want to get fastboot setup before trying this. Actually, you probably won't need fastboot, but you will need to restore your custom recovery.
Or use the longer method (takes more time, depends on your download speed), LG mobile support tool.
Once you get the stock recovery.img for your kdz, Open the p765_stock_recovery.zip and copy the 3-recovery.img into the zip file.
Note: Don't change the name of the recovery.img or it will not work
The recovery must be named 3-recovery.img
Place it on you sdcard and flash with cwm and reboot.
Or sideload into your phone with cwm and your computer
Code:
adb sideload p765_stock_recovery.zip

Don't listen to that guy!
1. Do you have supersu?
No: get it. Yes :
2. Go to supersu and scroll down the settings menu until you see "clean up for permanent unroot" press it.
3. Follow the instructions.
4. You are now unrooted!

If you have locked bootloader and stock recovery.
Never tried this, but after this you can go to download mode and check for sure if it says rooted or not!
I think if you need to return to stock for the update to lollipop better flash kdz and have a clean stock version, no rooted apps, no busybox installed. This is my opinion!
You must flash either your current version KDZ or the Lollipop KDZ.
That is because:
a) If you have the stock recovery and rooted system, then it will probably detect a modified /system partition and cancel the OTA update. The worst case scenario would be if the update, for some reason completed, it would soft-brick your device.
b) If you have a custom recovery, then it will do nothing, but it's possible that every time you try to boot back into the system, the system will boot you back into recovery, in an attempt to complete the OTA update.

ok thanks for your answers guys. i think the best thing is to flash the kdz..it`s more safe.
now let s wait for lollipop..

why you can't use lg flash tools?
Because it does not recognize the phone and gets stuck after15%, asking to try again.
I thought it was because of root or TWRP recovery but i found a solution using LG mobile support Tools in recovery mode.
I tried to go back to KK but after flashing and rebooting, it was stuck on LG boot logo.
Then i used LG flash Tools to upgrade to kdz 5.02 and it worked !
Now i run official Lolipop and i don't need to root anymore :
I needed root to run Foldermount to make Navigon App store maps on external SDcard ; it is possible without App now !
Thanks.
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.
Hello,
I need your help.
I've a LS990 for international use with Lollipop (5.0.1 and ZV8) and it was working fine. I tried to unlock the G3 so, I needed root so I used LG Root Script but by mistake I didn't notice I was using LG Root Script 2.4 for ZVA instead 1.2 or 1.3. Now, I can't access to internet through WiFi (I can connect to WiFi Networks but when I try to browse it has DNS problems or server problems, I tried other WiFi networks and same problem), I can't unlock it, I can't use 3G data and well, I thought to flash to stock rom and now the download mode has secure booting error certification verify and my laptop only recognizes it as QHSUSB_bulk in Device Manager. I cant use LG Flash Tool.
- I can access to Recovery Mode
- I can access to the System (everything is working fine except browsing)
Does anyone know how can I flash to stock ROM or fix these problems? I need root to unlock it and flash or update to ZVA and ZVB.
I was reading other threads but nothing.
Thank you

Reboot to recovery and flash the rom from the following thread. http://forum.xda-developers.com/spr...990-zvb-root-method-zvb-rooted-stock-t3211878
Also to fix download mode flash laf.img for your bootloader version. You can do that through recovery or in a working rom with root using the dd command. The img files for all of the partitions can be found at the following link. http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/stock_partitions
