[Q] how to revert to stock android on p768 ? - LG Optimus L9 P760, P765, P768, P769

Hi, i have a question about my phone, now i have CM11 on my Optimus L9 P768 (with bootloader unlocked .. and all that stuff), so i want to revert to original android... i tried a few ways to do it (with kdz and lgMobile support tool) but my computer can't find my phone after installed drivers. On the other side, with that KDZ-way i cannot enter to download/emergency mode (hold vol- and plug the usb or hold vol- and power button and plug the usb).
So my question is, can i install rom for P760 on my p768 (http://forum.xda-developers.com/showthread.php?t=2481243) that rom, or anyone can give me some help to revert to original stock android in a different way.

Hi bobpetar, you enter to download/emergency mode by holding vol + and plugging the usb.
Cheers. Good luck.

But in that way, i enter in S/W upgrade mode, not download/emergency mode. However, can i flash rom for P760 on my P768 ?

Same problem
I have the same problem, can't go back to stock room from Cyanogemond 11.
Maybe we have to restore a backup from a stock room and then flash?

sure you're in the right forum if you have a home hard key ??
key combo for vibrants is vol up and down and power or vol up and power with GB bootloaders
doing it with kies it automatically goes to download mode
and it doesnt matter if rooted or not
The button combination can be tricky to get into either download mode or recovery, just keep trying it eventually it should werk. You should probably look into purchasing a jig. Good luck!

No problem sir...

if all the above fail and are familiar using adb you can just adb reboot download .that will throw you into download mode. just a future reference.

[Q] Cannot get to download mode

I deleted framework-res.apk by accident instead of replacing it. My phone became unresponsive so I took the battery out and put it back in and once it turned on it gets stuck at the booting logo. I cannot get it into download mode either. I pressed vol up+down and then plugged in the usb. I've also hard reset it pressing the vol + home + power button. I've tried every button combination suggested on the forums and none work. When it connects to my computer it is detected as an MTP and not software/usb. Is there anything I can do to replace the firmware with a stock version? Thank you very much.

I did this and the phone got into the S/W mode and my computer detects it in the drivers but none of the flashing programs recognize it. I tried using the LG support tool, KDZ flasher, and LGNPST. None of them detect the phone. The LG Support shows the phone in the beginning to show the model and drivers, but once I click update software it can't detect it anymore and crashes. Any advice on how to get stock firmware in this situation?

Help getting into download mode.

I have tried the power + volume down and plug the usb into the pc and I get to the Modified recovery where you can go into safe mode or factory reset, etc. I have done it before but it was Kingo root that did it. It's not working because I can't get to usb debugging mode. I need to go back to stock. Thanks

If you are using the LGUP method, you do not need to even go into download mode. If you are on the Verizon bootlooped screen you should be able to flash it back to stock right then and there.
Also there is no real recovery method that you can use so you will have to wipe it completely clean unless you have backups.
LGup says phone 'unknown' so it won't work. It worked yesterday. Not sure what happened. Tried the battery pull method but it still doesn't work.

I had the same issue with my VS990. LGUP was not seeing the phone. Using the Recovery menu via power + volume down, I booted my phone into USB debugging mode. LGUP was then able to recognize my phone. I then chose the tot file, chose upgrade instead of refurbished, and clicked start. It auto restarted my phone into Download Mode and started the upgrade. If you can get the phone into USB debugging mode, you'll be set.

Plug a USB cable into your phone with your phone powered off, hold down on the Vol Up button and plug the USB cord into your computer. It should immediately boot into download mode. I have verified this works on my Verizon V10.

I just confirmed that works good job
Huh. I did mine from a regular boot up, but in debug mode. LGUP commanded it to reboot into DL mode for me.
Download mode on the LG V10 is achieved the same way all other recent LG smartphones have been. Power the device off completely by either the power menu or battery pull. Plug your USB cable into your computer. I didn't have an issue with USB 3.0. Hold Volume up and plug in the phone to the computer. Keep holding Volume up until the phone says download mode. It will do a small loading screen then it will change, this is normal. You can leave download mode by pulling out the battery or by holding the power button for 10-15 seconds.

I think you might be doing it wrong...
Download Mode -> Hold volume up, and plug into usb while STILL holding volume up, release once in download mode
Reset Screen -> Hold volume down + power, then plug into usb whil holding down buttons, release when screens comes on.
Ok, now for my problems. I got my phone into DM, used LGUP to install VS99026A_00_0118.kdz on my VS990. I let it go overnight. Came back to see it failed at about 73%, Error "can't get laf property", ever since then I can't get back into DM again, my LG splash screen will come up, then I get the android guy saying "Erasing...", then it reboots to splash screen again, waits a sec, then turns off. I managed to get into the reset screen with vol dn + pwr + usb method, tried to go into safe mode, now I have same issue getting back to that screen too.
Any help?

1. no open
2. does not see pc
3. no recovery
4. no bootloader
5. fully dead
HELP PLS
from everyone sory my bad english
Can you shut it down? ( Turn it off)
To unbrick the easiest way is to boot into bootloader (Unplug USB, Hold Volume Down and plug USB cable).
Then you flash a stock system and a stock recovery.

How did you remove the bootloader?
try this first :
1. make sure your phone turned off completely.
2. press and hold Volume Down button, and plug usb to your phone and to pc.
3. let it like that for 30 minutes.
please response back to me if your phone get into fastboot mode.
