LG G Pad x won't boot - LG G Pad X 8.0 Questions & Answers

I have a stock t-mo g pad x. I don't know what version OS it was on, but it has sat unused for some time. I took it out recently to run tinycam pro. It ran for a few days, and last week it just started rebooting itself and goes into a boot loop. I let it be a few times, and suddenly it won't come back on anymore. When first started using it, there was an update, which I did not accept. I wonder if it updated itself and screwed itself during the update?
When I tried holding the power button, power button plus volume down etc etc, it just vibrates after 15 sec and does nothing. When plugged into charger, it shows nothing. I opened up the back and checked the battery voltage, 4.1v, plenty of power. Is there any hope of reviving this thing? It's practically new.

Frozen at boot; won't turn off

Hey,
Just got a g tablet this week and I've been playing around with trying to get VEGAn onto it.
After installing it from CWR, it rebooted to the boot screen (three parrots) and now it won't do ANYTHING. I can't even turn it off (holding down power for 10+ seconds doesn't do anything)
Has anyone seen this before? I see many threads about boot loop but I can't even get my tablet to turn off so I can reboot it into APX mode to use nvflash.
Should I just let it try to burn through the battery overnight and see what happens in the morning?
Just keep pressing the power button for 3 second of length, it will turn off
Yeah that usually does it, but this time it's stuck at the screen even if I hold the power button for minutes.
I guess I'll just wait to see if after having it shut off via draining the battery, it is in a usable state.
My tablet must have gotten itself in some very weird state.
After letting the battery drain, it came back to life this morning.

Hard Brick/Black Screen 5.0 [SOLVED]

My 5.0 is hard bricked. Black screen, won't charge, won't turn on. When plugged into outlet or computer, still black screen.
I rooted it back in December with no problems until today. Decided to plug it into an outlet to charge it since battery was around 50%. After about 30 minutes, used it to check weather, etc., then I did a quick push of the on/off switch to turn off the screen. About 2 minutes later, went to turn it on and got the black screen. I decided to leave it plugged into an outlet for about 1 hour and still nothing.
Looking at other, similar, bricked posts for the 5.0, doesn't seem applicable to this completely dead device (wasn't installing a rom or doing anything unusual).
Any help is greatly appreciated.
Solved
I was able to fix the problem, without losing any data, by going into recovery. For others who may run into similar issues, I did the following:
Pressed the power and volume up key simultaneously for about 10 seconds until the SAMSUNG logo appeared.
Selected 'reboot system now' and pressed the home button.

Phone will not power on (Sometimes!)

I am not sure if I should be concerned, but this has now happened twice. Sometimes I let the phone slow charge from my desktop PC. This morning, after turning the phone off last night, it would not power on. It was connected to the desktop when I shut it off last night. This morning, with the phone still connected to the USB port, I turn on the V10 and nothing! To get it to power on, I had to hold the power and volume down button for about 15 to 20 seconds. I have been connecting it to my PC and my work laptop since I bought it last May. I did not have the problem until the latest update that was just pushed to the phone. Has anybody else had this problem?
Mine has started doing the something, it shut off for 2 days with boot loop issues, just came back on after i brought a new phone.
Having the boot loop issue here. Verizon just told me in chat that the latest update is known to be causing boot loop issues. Maybe it's possible it also stops these phones from turning on at times. I'm hoping to get mine to start up before having to send it back to Verizon or LG.
I have most recent software. I turn the thing off and on constantly. Mostly by switching batteries. Hopefully this doesn't happen to me. As it is, I most likely WON'T be buying LG again.

Moto Z Droid Hard Bricked After Botched Update?

Today, my mother was running the latest update for her Moto Z Droid. After a couple minutes, the display went off, and the phone was dead. Won't go to logo, won't power on, NOTHING.
She said the battery was at around 40-50% battery during the update, and I've tried plugging it into a power supply, and also tried plugging into a computer, and NOTHING is happening.
Is there a way to get the phone back working? Thank you for your help!
I had this problem too just today and yes my battery was 40% and yes the screen went blank and no response for 2min. But i did not plug into charging nor PC. I long pressed the power button after 2mins and it took a while to power up and continue the update. I'm sorry to say but it is advisable NOT to plug in anything during update. Maybe you should bring in to Verizon.
Sort of related, sort of not... I got the Moto update today (UK sim free Z) and I thought it had stuck too. Just kept rotating between blue & lenovo screen for ages, then black, just as I was getting nervous it continued and finished with all OK. I had plugged it in BEFORE it started, as that's what the message said to do.
It said something about notification update but I can't see any difference?? I was hoping for 4 volume controls like every other mobile on the market (?) but no
Does anybody know what actually got changed?

SM-T560 charge/boot issue.

Hi,
I got hold of one of these tablets that appeared dead, left it charging overnight and it started without issue, the battery was at 67% at this point.
I then shut it down and held the Home + VolUp + Power to enter download mode as I wanted to install TWRP.
Nothing happened, but not only that, the tablet failed to boot again whatsoever. I took the back off and unplugged the battery, held the power button down for 30-40 seconds, reattached battery, still nothing, so I decided to leave it on charge for a bit more and try to figure it out later.
Later came along, and I picked up the tablet and for some reason pushed the home button 3 times and it displayed the battery icon, showing 100%, great!
It still won't boot though and I haven;t been able to reproduce whatever I did to get it to show the battery icon again.
I've tried every combination of holding down Home/VolUp/VolDown and Power that I can think of for different amounts of time and still nothing.
Had it plugged into the computer too and monitored dmesg for any signs of life and still nothing.
I'm thinking (but hoping not) that it might be a physical problem with the power button, but it feels fine when pressed.
Is there some magic trick that I don't know about that could help here?
Many thanks.,
g
EDIT: I have left it plugged in for a few hours and periodically the battery icon appears for a while (now at 99%), then disappears. Tried to switch it on with the power button while the icon is on the screen but no go, same with different button combos.
