My sister transferred the android files and ran the install on my touchpad without checking to see if it was in developer mode (I don't know if that is relevant) after she ran the install it came up with an error, turned off, and now it is stuck at the hp logo when you first turn it on.
When I hold the power button the screen turns off, when I hold it again it turns on but it's stuck at the logo.
We tried webos doctor but it was getting stuck at 8%
any suggestions?
Sound like you have corrupted USB partition.
Go here. Happened to me. It worked!

Will not pass the HP logo
I have a touchpad that is stuck on the logo and will not do anything except charge and deplete that charge. I was attempting to install CM10 on this pad, after being successful with numerous others it was just a normal walk in the park. I had just recently used the cm software on my personal pad and it works perfect. I did the install as normal, at the end the pad began to boot up and stayed in the logo screen. I have attempted to use the debrick and other methods of repair to no avail. I would like to fix this problem prior to the complete end of HP support in January 2015. Thanks so much for any and all assistance in my endeavor to fix this pad.

On rooted ZV6. I was using the phone as usual. I went to open an app (Weather Channel, though I don't believe that matters) and the phone froze. It did the self-restart, however it sits at the very first LG flash screen, turns off for a second, then starts again. Continual boot loop.
I've popped the battery, tried a different battery, tried with the SD in and out, all with the same results. I tried holding down volume down and power, it gives me the booting into recovery screen, then goes back into the boot loop.
I've seen the talk about the ZV9 OTA, but there was no sign of an update in progress when the system crapped out initially.
If I'm reading the code under the back cover right, the phone was made back in May, which makes me worry that it's the known faulty hardware issue. Does anyone have any ideas I can try before going through the hell of riding Sprint for a replacement? I would be forever in your debt for something to save my phone. Thanks in advance for any advice.
EDIT: After screwing around with holding down volume buttons at random times, it will sometimes get to the Sprint Spark animation, but no boot sound, then as I was typing this edit, it magically booted proper, and powered down, and is boot looping again. What the hell.
So I can't boot my phone. Previously stable h811, unlocked bootloader running latest 20i Extreme 3.3 MM with G4 Tweaksbox. I have a Qi/NFC sticker on the back, but which has worked flawlessly and was not in use when the phone died. Here's what happened and what I have attempted.
Problem began when phone simply went black. The only thing running was Maps, which had a route displayed but was not in navigation mode. The screen went dark like normal, and when I went to wake the phone, nothing happened. I was in the car and tried plugging in the car charger and did not get a charge light. Pulled the battery and was unable to get a response. The phone and battery were quite warm.
When I got home, I tried a different battery, and the screen turned on to the LG initial boot screen, but nothing else happened.
After many battery pulls and attempts to boot into recovery, I tried it with the phone plugged into the computer. Finally, it showed the charging screen and light, and after several more attempts- pulling the battery and inserting it, then powering on, it appeared to be booting, (boot animation started, but then looped and froze on the initial boot screen (with bootloader state: bootloader unlocked in the upper corner). After another round of attempt/battery pull, it booted all the way up, but at that point I had my sim pulled. Pulled the battery and tried to restart and it froze on the initial boot screen again. Haven't been able to get into recovery at all, can't get into download, can't boot past the initial LG screen. Sometimes it loops, sometimes it just hangs. Nothing I do pressing combos of buttons, plugged into computer or unplugged, seems to change anything. The very farthest I've gotten is the breathe blue light before the boot animation, but then it looped. Now it's boot looping plugged into the computer.
Any ideas? I'm at a total loss.

Im bricked myself from another issue but i think there is a black screen of death issue with some of the g4s

The g4 is just not a good device or user friendly
Sent from my LGMS631 using XDA Free mobile app
Black screen of death here too
Yesterday, I was using Chrome, site loading, screen just went black. I had about 1/2 battery at the time. I figured maybe the battery was just reporting wrong. When I got home, swapped batteries, same issue. I've been able to get into recovery and attempt a factory reset a couple of times (after many frustrating attempts.) The phone seems to only be able to be powered on for about 30 seconds before it goes black again. I'm going to attempt to fix with download mode now. If anyone else has solved a similar issue, any tips would be appreciated.
Hardware appears to be at fault!
Check this out, people!

Spread the word. Sounds like this is our problem. Apparently affecting mostly models with serial numbers starting 505xxxxx... which is what mine is. Called LG and they issued an RA# and shipping label to send it to them for service. I'm a little concerned since I didn't buy mine through a carrier, but this seems more like something of a soft recall than strictly a warranty issue, so I'm hoping they fix it no questions asked. I'll keep you guys posted on the progress.
Same thing happened to me today. My phone randomly shut off and it won't boot. Its stuck at the Android logo. I wasn't messing around with it. Just normal use (Snapchat, youtube). I tried booting into recovery but it just goes back to the android screen LG logo and keeps looping. I at least want to wipe the phone before I send it (personal info).
Same here. Mine has serial number starting 505, was purchased back at end of 5/2015 with not problems until this. I filled out the warranty repair form on LGs website and they sent me an RMA with label to get it fixed. I sent it in, they sent it back, and the only thing I see is on one sheet they printed out and included in the package said 'replaced board'. However, when I started up the phone it looked like new initialization with xx of yy apps initializing and then it began bootlooping with the LG splash screen. So frustrating!
So, this time I contacted t-mobile via their online chat, and did a warranty exchange through them. They will send me a replacement LG G4 next day ups air and I will send them the defective one for them to claim warranty themselves. We'll see where this goes. I might just take the replacement unit and do a tmobile jump exchange to another device. I wanted to wait for the new line of HTC nexus phones that are rumored for this year (and was loving the LG 4 until it died), but I might need to just jump twice this year and go for something like the new Samsung S7 of new LG G5 now and then again switch to HTC nexus once that comes out.
Sent mine to LG, and they fixed under warranty with no questions asked. Got it back within a week. All good now.
Hi, so I got an A2 which has been submerged in water for a while. I was not turning on at all (just showing the white led light blinking), so I bought a new USB part and battery for it, replaced it, and now it seems to react.
However, it keeps switching between the charging logo for a second, then vibrates and shows the Android One logo (this switch goes on and on forever). I have tried the button combo to go into recovery, but as soon as the Android recovery boot logo appears, it'll still timeout into the charging logo.
Does anyone know what may be going on? Or what component to replace? (the phone was only days old when it accidentally got soaked, so everything is new and it's a shame to just throw it away)
Ive been using this for 7 months now. I flashed it from CN to WW successfully and was using it for 4 months up to this point. The phone's problem is that it always gets stuck at boot and loops for about 3-4 times before going to a complete state of unresponsiveness (black screen) even with force restart i cant get it to respond and have to wait for several minutes and try lots of times before it responds and it boots and again loops till it proceeds to black screen. It was completely random. I was playing some game till it suddenly freeze and rebooted , that started the loops. Sometimes at the boot screen with the ROG logo it shows strange white lines that wasnt there before, like its glitching. I've already done factory reset and still the same situation.
I sucessfuly entered the phone setup once and used it for like 10 mins after reset then when I rebooted it, it went back to looping and black screen. I hope someone can respond to this, I desperately need help.
