Black Screen of death. - AT&T LG Optimus G

Help. I might have a black screen of death or stuck in downloading mode. I tried powering it on but nothing. I plug this thing into the computer and it seems to respond when I plug it in but still nothing on the screen. This just happened all of a sudden, i don't believe this is a result from a bad flash.

[q] rezound wont turn on :/

I'm very much new to this, so please take it easy on the terminology, and insults.. :/ Just to be clear ive never rooted this phone or flashed it or anything like that.
I was using my phone and the battery ran really low and it died. I went to turn it on, and it wouldn't turn on, so i charged the battery for a good hour. I press the power button and it vibrates, but the screen stays black.
after that i tried doing a hard reset, so with the phone in that black screen, i took the battery out so it would turn off. Put it back in, followed the instructions for hard reset from the VZW website (without turning the phone on, because i'm still unable to do so), and nothing happened at all. I gave it a couple tries and still nothing.
Then i took the battery out, put it back in, pressed the power button. I felt it vibrate again like last time. So in this post-vibrate state, without removing the battery, while the screen is still black with no power on, i did the hard reset. It vibrated and then now the 4 touch buttons at the screen illuminated, and the backlight turned on, but the screen itself was still black.
can anyone help me out??

When the phone is completely off. Battery pull. When holding down (Vol Down + Power). Does the HBOOT (white screen) appear or is it still black?

Do you get anything when you plug it into a computer? Any new devices that the computer sees? If not. Need to bring it to the Verizon store bud :/

I would say go to tje Verizon store and have them charge your battery. If it takes a charge and powers on then it prolly your port.

[Q] Phone got stock, finally work but..

Hello everyone,
I got a question. Yesterday, my phone shutdown do to no more battery. Once I got home (about 1h30 after), I plug-it into my computer for a good slow charge. I noticed the led was blinking red instead of staying on, but I though it was due to critical low battery. After 3 hours, still the same. I try to open it but nothing happened. Then, I noticed that when I touch the screen or button, the phone vibrate.
I then unplug and try again, same thing. I try plug into the wall charger, samething.
Then I proceed to hold the power button for 5 seconds. All three touch button start flashing and stayed on, but no joy, still vibrate when touching anything with screen turn off (not just no backlight, no image at all).
I manage to found out that holding the button nearly 10 seconds, it force a reboot and then was OK and charged at 70%.
I'm wondering what's the deal here. Is it a problem with the stock rooted rom?
Thanks

Think my Note died -- Help?

Randomly today my phone on Blackstar X was rebooting a ton. Then, suddenly, it wouldn't turn on. Well, it turns on, then it shows a screwed up version of the Blackstar X logo (screwed up as in its all pixelated), and then it turns off. As soon as I connect the battery, this happens. I don't even turn it on when the battery is connected, it just happens. It's as if it's in a state of perpetual random-rebooting, but the phone memory/ROM died.
I can get into download mode, but like 2-3 seconds in, it turns off. This keeps happening. When I try to hold both volume to get into TWRP, the phone just keeps vibrating (only black screen, meanwhile). Any one got any suggestions? I just want this f**ing thing to work!
Sounds like your power button is stuck.

[Q] Phone won't boot, won't go into recovery

Hello everyone,
Last night, my phone randomly shut itself off. I have been using the Novena ROM for months now, so I wasn't doing any flashing or anything. Then it wouldn't boot up. I would take out the battery, put it back in, it says "Samsung" for about two seconds then shuts off. If I try and get into recovery, the phone keeps vibrating, with a 2 second interval between each vibration. Same thing happens if I connect to PC or to power outlet. Any ideas on how to fix this strange issue?
Thanks for any input.

Sounds like your power button is stuck. This happen to me before. Try tapping it rapidly a bunch of times, or try flicking the back of the phone by the power button with your finger.

Won't Boot, ODIN MODE Turns Off In 2 Secs...

My buddies rooted i717 with CM10 4.2 has been running great. Then it started to turn just turn off on it's own. Last time it turned off now it won't turn on.
When you hit the power samsung logo flashes normally then screen goes blank. At this point it keeps making that powering on vibrating sensation repeatedly. Touch power button and this routine repeats.
It will not boot into recovery. After the sammy logo flash continuing to hold down power +/- does not yield recovery mode. It just starts the vibrating loop.
I thought I will just install stock via kies or flash JB via odin. Well odin mode turns on ok but shuts off after barely 2 to 3 seconds. I have tried this with and without battery, plugged in and not plugged in on pc but end up the same way.
I have checked battery, same is super aok. I swapped batteries with my i717 and mine turns on just fine all the way. My buddy doesn't mind any which way the phone comes back to life.

If you read and run any kind of search, you would find similarities to the all common stuck power button.
Flick tye back of the phone a few times.
I know, you can feel it click.......doesnt matter, flick the phone.
If you are brave enough, you can open phone and clean with qtip and alcohol.
I am not.

I did actually, it didn't work. I thought there's was something that could help before I have to open it up cause of time. I change ports, cameras, etc on these models so it's not a biggie to clean it. Will do this this weekend.

There have been multiple times that I couldn't get into recovery mode, but download mode worked fine.... I just reinstalled CWM and reflashed.
May not help the root cause, but may get you past the no-recovery mode issue.

Neither works. DL mode turns off after 2-3 seconds; I have even induced it with a DL dongle. Repeats the same. Recovery mode is a no go-phone flashes sammy logo and goes silent. You are right the first issue to fix is the power button. I will update this weekend once I take it apart. Thanx all the same.
