Lg p760 Dead boot - LG Optimus L9 P760, P765, P768, P769

During normal use the phone just locked up and wouldn't respond so I took out the battery and put it back in expecting for it to just turn back on but it just stayed at the Lg logo and I realized what had happened, (I have had multiple issues with this phone in the past) I just shoved it in my pocket and went on business when I pull it out again and the screen is black I click the power button and it shows (Translated from polish)

Reset phone
I've had this happen once before so I sighed angrily and pressed the button to wipe my phone. Nothing again nothing, again and nothing. The button wouldn't do anything. So I reboot it and this time it just hangs I let it go for 3 days straight on the LG logo. I try various methods to reflash the phone back to a working state none of them work and the last one is what shattered it. This is the link for it: http://forum.xda-developers.com/showthread.php?t=2748384 I try using that tool and it goes to 27 percent and fails so I try again and it the process won't start so I (apparently not learning my lesson about rebooting phones) take the battery out and try to get into s/w mode again. It won't go so I rush to my only computer with fast boot working and I couldn't get anything to flash onto the phone. The partitions are missing apparently. So how do I reset my partition table so I can reflash my phone. Note I did try this method: http://forum.xda-developers.com/showthread.php?t=2546571 but the LG software kept erroring about 25%.

Stuck booting.

Today my phone was bring finnicky and locking up, so I restarted it. Lo and behold the thing won't even boot. I don't even get a boot animation. I get a flash of LG for half a second and then blackness. Couldn't boot into recovery, so instead I booted into download mode and LGNPST back to JB stock. Now it won't boot past the AT&T logo. I see LG, AT&T, hear the little jingle, and then the screen stays the same. When I power the phone off it auto powers itself back up and tries to boot again. Endless cycle.
Anyone have any idea what's going on or how to fix it? I'm lost at this point and fear that I may have inadvertently bricked my phone. Really can't afford a new one...
You could try factory reset from stock recovery. The button combo is volume down plus power. There will be a menu screen if you get it to work.
Went in to AT&T support and that's what the guy did. It worked. Thanks, wish I had seen this post before making that drive.

[Q] phone wont boot after flash attempt

A couple days ago, within an hour of using my phone and everything seeming to be fine, my phone got stuck at the Galaxy Note II logo. Thinking that it locked up and reset itself or something like that while in my pocket, I pulled the battery because it didn't respond to the power button. after I replaced the battery and turned it on, it stopped at the same screen. After a few attempts, I tried to get into recovery mode and it only got to the download screen. After some research, it sounded like I could maybe flash the stock rom onto the phone and get back up and running. so I downloaded ODIN and found what I thought was the correct ROM and tried to flash it. ODIN gave an error about unable to find a PIT file, so more googleing later, I found a PIT file and tried again. ODIN tried for about 10 minutes and then failed. My phone was still on the download screen so I thought to just try the process completely from the start again. I unplugged my phone from the computer and tried to restart it, I think by holding the power button down but I may have just pulled the battery. once my phone turned off it hasn't turned back on again. It wont even attempt to charge when I plug it into the wall.
So I ask the people who are far more experienced with this kind of thing, did I unrecoverably mess up my phone, or is there something I can still do?

[Q] Bricked Lg G2

Hi there! I'm a stupid-stupid person. I was trying to get Lollipop faster, so I tried to flash lollipop on my phone.
I managed to root it, but haven't done any backup, except for media and contacts.
I'll try to explain what I've done.
So I rooted the phone, entered the download mode and then I tried to flash it using LG Flash Tool 2014.
When in download mode, it was stuck at 0%, so I didn't wait to go ahead, I tried to flash it.
Now, the flash failed several times. The phone was alright then.
Further, I tried again and at some point something happened, it got to two percent, it wrote COM4 and then it failed. It might have been my antivirus that stopped the process, I'm not sure.
Well, now I have a useless phone. It keeps showing the LG logo.
The hard reset doesn't work, it's not recognized in Device manager, and it doesn't work download mode.
When I try to power it off it does so only after a long press. At first, when the screen goes black, if I release the power switch, then it will reboot again. If I press it long enough, the phone will power off.
I'm desperate, of course.
The phone was running Kitkat.

LG H850 - No boot, No Recovery, PLEASE help

Hi all,
To get right to the point, my phone doesn't switch on, and I cannot get into recovery/download mode.
The story:
After my apps kept on crashing for no reason, I restarted the phone. After the restart, when it asked my pin, the google app kept on crashing and the phone completely froze up.
Here is where I suspect I made a HUGE mistake. I Took out the battery and started up the phone again. It immediately told me that the system is corrupt and "cannot be trusted".
I continue the boot process, only to land in a boot loop. I take out the battery once again and restart the phone.
After displaying the LG logo, it just turned off. And that was the last time I could get it on.
I tried booting into recovery, but the phone won't even switch on to begin with.
Absolutely no response. Screen stays pitch black.
I tried doing it with the USB cable in, same result. Nothing.
I also read up on the different combinations to get into download mode to no avail.
Stock ROM and firmware installed, no mods whatsoever.
Android 8.0
Can anyone please suggest anything I can do to save my device?

V30 suddenly stuck in boot loop. Any ideas?

My V30 worked perfectly for years, Android 9 running, had it rooted using the sticky guide, and Magisk installed. I had just boarded a plane on Monday, sat down, and noticed the LG screen with the bootlaoder unlocked message warning you always see when rebooting. Then it just reboots again, I see the LG logo, the bootloader warning message, reboots again after about a minute.
I also could not turn it off because it would just turn itself right back on, and go back into the loop. Eventually the battery drained and it died. When I got home, I held the power button and the volume down then plugged in to go into I think it's recovery mode, which worked, but my only options were to flash or reboot (I think, my memory is fuzzy). Then I ran LGUP and it detected my phone, but said it can't load the model from C:\Program Files\LG Electronics\LGUP\model\com.
Next I tried running adb commands against it which is working, however I"m getting back LGUS9983322eaa5 unauthorized which I don't understand because I clearly had debugging turned on (which I think is what causes that message?)
Any ideas on what to try next, or what could have happened? I had not installed anything new. This data recovery company called Drivesavers quoted me 900 to get my files off, but I have backups, and there's nothing on the internal memory I can't live without.
Thanks for your help!
