[Q] LG L9 P769 Stuck in boot loop? - LG Optimus L9 P760, P765, P768, P769

Hello guys!
I installed the stock JB ROM V20H and now I can't go trough the LG logo on the boot. It vibrates, shows the LG logo for a couple of seconds and then turns off.
What should I do??

Do you tried to enter in download mode?
Step 1. Download LG Mobile Support Tool from here tool.xcdn.gdms.lge.com/client/app/B2CAppSetup.exe
Step 2. Take out battery, then put it back while holding both volume up and volume down and then connect your phone to PC through USB.
Step 3. While phone is in Download Mode, open LG Moblie Support Tool, then click Options, then click Update Recovery.
I hope it helped.

Sorry, I mean S/W Upgrade Mode.

The process with the LG Mobile Support Tool stops at the download part. Timer stops, no progress bar is moving.

I somehow managed to install the default stock rom V20H_00.kdz , but now my screen is inverted. What to do??

First of all, what are you trying to achieve? Unlock bootloader? Stock ROM?

Hi,
dont panic, I went thru exactly the same process right up till the TWRP and wipe. All you need to do is get hold of the stock rooted rom zip from here:
Then copy it onto your sdcard, for which you can connect to the computer using Advanced menu of the TWRP, and load the sdcard, which will connect as USB storage to PC.
Then once file is on sd card, just go back to main TWRP meny and select install option, then select the zip file you just copied.
Let TWRP do its stuff, then do a factory reset / then go into reboot system.
Wish you all the best. Once the ROM has installed, now you can search for the latest TWRP, install it then go on to latest kit kat roms in exactly the same way.

hope he follows up with a thank you.

Hii,
Finally I reached on TWRP. Can I copy the Stock ROM Zip file in Memory Card and then install memory card on phone. And from Install in TWRP I can go the SD Card location and install it from there? Possible ?
Actually there was no battery on phone that is why the phone was not booting up to TWRP mode. Now I'm in TWRP and downloading Stock ROM. Hope it get fixed soon.
Many Thanks and Regards

That file is stock firmware inside the zip is a .tot file that can be renamed to .bin and used with lgnpst to bring the phone back to stock. You would need to be able to get into download mode
again. If you do use the g33k3r file you would need to root again then use Freegee app from play store to unlock bootloader and install recovery.

Hi,
Now I'm downloading ...
ttp://downloads.codefi.re/thecubed/lgoptimusg/att/firmware/LGE970AT-00-V10o-ATT-US-SEP-29-2012-0.zip
I guess this is original ATT LG E970 Firmware. I will copy it into my external Memory Card and then will insert into phone. After that using TWRP I'll be going to use this Zip file and after that factory reset. Am I correct ? Do I need to follow different steps ?
Let me know. Moreover do I need to unlock Phone again? When I received it was already in Unlocked State. So installing the above link firmware will lock it again? Or should I proceed with the link I posted earlier, I mean this ..
ttp://downloads.codefi.re/g33k3r/LGE970AT-01-V20j-310-410-MAR-08-2013.zip
And Rename File to .bin instead of .tot and Make ZIP it again ?
Please let me know.
PS ; I'm still Downloading The firmware from Ist link.

Please help?
Edit : I also tried Unticking ZIP File Verification. But still it says .. "Error in Flashing Zip"
I did this from the forum @carrett started:
Obtain the following files: AutoLGNPST-tSilenzio.zip (available on IRC or googling), and the firmware (http://forum.xda-developers.com/showthread.php?t=2219953). Unzip AutoLGNPST-tSilenzio.zip and follow the instructions in "READ ME FIRST.txt" (mad props to tSilenzio for automating this process).

make sure to download the first file too.... to get to download mode just use twrp's reboot menu... from what i remember it has a reboot to bootloader. From there you can use the volume keys to select Download mode and push the power button to go into it...

I tried reboot to boot loader but unfortunately it takes me back to Fast Boot mode (in green Andriod screen) :/
I also tried all options of reboot but no use. Either the phone comes in Fast Boot mode or Power off.

3 questions:
1. I guess it should work on all L7 II series, right? I'm asking this as I have the P714 device.
2. Please elaborate on step 6, not sure I understand it.
3. Any risk to brick the phone? If so, what's the way to recover?
Cheers,

I have a doubt:
you say that the phone will restart on recovery mode ¿ will this happens every time I boot the phone or only through this program?
I'm willing to install it on a p712

Only once, after applying these steps.
another doubt:
¿is there anything you can flash on the L7 II, or what's the purpose of using cwm at this point?
has anyone tried backup and restore, wiping battery stats? which other features that can be used at this stage are provided? p715/v10i/india/vroot1.7.6
Also works on P710 (L7 2). Didn't run the script pushed APPSSBL.bin and recovery on sd then put them in dev/block/. Works good i can make backup, restore and flash but there is a problem. If i leave the phone off for some hours when i start it it will go into a bootloop. To stop this I need to take battery out and open the phone using external charger.

To stop this (bootloop) you need to take battery out, and then put battery back, connect external charger, and press power button... Right?

No to stop the bootloop i do this. Plug out battery for 1 minute. Start the phone with charger only. If it doesn't work wait until a yellow triangle and battery comes then push battery in and open phone. But i flashed the appssbl again using adb from that rar and i didn't get bootloop.

Hello Riskey,
Unfortunately I did.. And the method mention below by Christi also did NOT work. Whenever I plug the charger to the phone, it shows LG symbol and goes to CWM recovery.. However I flashed stock Rom on my P715 and its fine now. The problem I think qas an update.. The phone took an update from LG which said 1 app to be updated.. And when I restarted the phone this isaue occurred.. Maybe this will help you?!

Sorry man maybe it is different problem because I am running it on a p710 with latest firmware the 10j one. Anyway you can always recover bootlop with Kdz flasher. For those that don't know how. Pull battery out. Wait 1 minute or so then press Volume-Down and hold it while you insert your usb. There will be a yellow screen (Emergency Mode). Be sure to have all drivers download the firmware for your phone, run Kdz Flasher Type: 3GQCT - Phone Mode: Emergency and run start. You will recover the bootloops.
OK, so I tried to see if this fixed the bootloop problem (do I have a death wish or what?). With the previous version of CWM, I booted to recovery mode from power down - got the bootloop (recovered with battery out and charger plugged + home).
Now, flashed the new image. Succesfully got to CWM via reset to recovery from power menu. However, when trying to get to CWM via button combination (power, vol up & down, home), I never get to CWM but only to regular boot sequence. Tried maybe ten times, always the same. Anyone can explain?

Hi ,i have the same model,does this recovery works fine? i mean ,does it have bootloops problems? and to answer your quesrion,try using this combination:
Power button + up volume + button home
after the vivration just release the power button and keep pressing the other 2 until you reach the recovery screen.
Tell me if its works,and also if the recovery is stable for the p714,thanks

Thanks mate. :good: This combination brought me to the recovery menu. Don't know why I didn't think about it - was the same with the Samsung device I previously had.
And I can confirm that this fixes the bootloop issue. We have CWM for this device.

[Q] Help recovering an unrecognized device

Hi all,
I have a major problem with a friends Galaxy S 2 GT-i9100, he flashed a cyanogen custom rom and tried to uprade it but somewhere in the process the phone just died and no the phone in not entering recovery mode and whn we plug it in to the computer it is not even recognized as a usb device, so we can't even try and re-flash it.
Can someone please tell me, how can I fix / recover his phone so it would just turn back on ?

Can your friends phone go into download mode (volume down, home button, power button)? If it can, you will need to flash back to stock rom by using odin.
It's complicated

No, in download mode. Connect your phone to PC when phone is on download mode then see if device manager picks it up.
Oh

can you enter download mode ?
if you can just flash kdz with a normal way or if you don't have any data to loose with CSE way
Don't worry, it's a soft brick.
Get the phone in download mode and flash a kdz for your device.
You may have to do a factory reset, but don't until you have to.

Plug a USB to a PC with LG 's drivers installed, hold Vol- on your device and plug the other end of the USB cable to your device.
(That's probably it, I can't remember for sure. If it's not, then Google it)

I've been flashing my LG G2 MINI (D620K) since last month and the problem doesn't seem to go away. I flashed, it works for a few weeks but then my phone just reset itself and the logo stucks again. I was hoping that you happen to know a solution

Root TOT VS990 Tungkick Boot Failure

Hello all,
I am experiencing a boot error telling me to using the Verizon Software Repair Assistant and that it is experiencing an "Authentication Fail #9 [Modified].
Can someone link to the repair tool? I cannot get the assistant now that the phone refuses to boot. Or if someone has a different solution they are welcome to offer it.
Much thanks.
Curious as to what what system you are using, windows 7,8,or 10?

Windows 7. I should add that it may be due to something external from the root. After rooting I installed a few things, rebooted, then a few more things were installed, and rebooted and then this came up. It may be after installing and setting up Chainfire's Liveboot app.
I am in the same boat. Stuck on "Start Up Failed". Computer will not recognize the phone. I dont know what to do. My Verizon Repair Assistant is from my Galaxy S6 Edge & doesnt recognize my LG V10. Any suggestions or assistance would greatly be appreciated.

Otherwise you should be able to boot into download mode and use LGUP with a .KDZ file to restore the phone back to factory.

You can't pull the battery and get it into download mode?

Yeah, I am still having trouble getting the device into download mode. I can get into system Recovery where there is a menu, but no "Download Mode"

Power off your phone. Then hold down the Volume up button and plug your phone into the PC and the phone will boot into Download Mode. You can't do it from recovery.
Okay. Got it. It was just being a little finicky. Thanks.
