[Q] rebooted my phone and it won't turn back on - Sprint LG G3

I rebooted my phone and it didn't turn back on. I tried to plug it into my computer but it did not show up. When I try to turn it back on the screen just stays black. I am currently running Vanir lollipop if that helps. Can anyone help me get my phone back working or is it a lost cause.
I don't know what happened but my phone rebooted and it works perfectly.

Airplane Mode/ Reception/ Wifi Problems

I am currently on Android Revolution HD 4.0. I wanted to update my phone to ARHD 5.1. I was told that it is not necessary to flash the firmware so i just ignored flashing the firmware and updated to 5.1. After i rebooted the device the phoen was stuck on the htc one x screen and would not move for more than 10mins. so i restored all my 4.0 data and boot. After restoring the data i was back on my phone working and realized that airplance mode was on so i went to turn it off. on the screen showing the airplane mode wifi and etc. the airplane mode button is stuck on off with the status turning off. and the wifi on on with turning on status. If anyone know how to fix this i would really appreciate it. I am planning on flashing 4.0 again just so the phone works.
this is pretty much how it looks no matter how long i keep it on that screen or do anything it is stuck like that. i can not call or use wifi.

[Q] Screen won't turn on, even on reboot

The other day, I went to restart my phone (had to pull the battery, since it was nearly completely frozen,) and when I turned it back on, the screen flashed the HTC screen for a second, then went off. Everything else on the phone works fine. I can adjust the volume, receive notifications and texts, and use the touch screen.
Is this a hardware issue, where I would need to replace the screen, or did the software go screwy somewhere and could be fixed with an adb ROM flash? Thanks!
Try reflashing your rom.
If this doesn't help try another. Sometimes it's not working properly. So just try again.

I can try that through adb, although it was working mostly fine before the reset.

[Q] Galaxy S3 won't turn on.

Guys, help me. I restarted my phone and it froze the screen like a grey fuzzy TV screen with a constant blue LED light.
I then pulled the battery and put it back in and tried to turn my phone on. My phone didn't turn on.
It isn't giving my any feedback. Nothing comes on the screen. Tried volume+power+home and all the other combinations of keys.
I've tried charging it and trying again, it doesn't work. Nothing is working.
It hasn't been dropped or waterlogged. It was working perfectly fine before I restarted.
Any suggestions? I rely on my phone for important work calls so I need to get it working ASAP. Any help would be deeply appreciated.:crying:

If the download mode doesn't work -> service center.

I think the device may be out of warranty and I want to be able to revive it with internal memory data intact. Not sure if service centre would recover it with data intact.

Help LG G5 VS980 not booting properly problem

Hi, I was using my LG G5 while plugged in, all of a sudden it acts weird, app crashes, lags and a few part of the screen goes black for a short moment. It then shuts down and restart itself, but stuck on some sort of a bootloop (it passes the logo screen but then the LCD goes black and keeps turning itself on and off repeatedly with nothing in it, also the LED light is showing blue)
I took off the battery, put it back in, and turned it on. But it ended up the same. So then I went to the system recovery menu. The recovery menu works just fine. However I've tried using its safe mode, wipe cache, factory data reset, continue power up, and none of them seems to work. It just stuck on that bootloop.
Since I was getting desperate, I left the phone in the bootlooping state for awhile.. at some point it started normally and goes to the choose your language menu (because of the factory reset I guess). I was so relieved, until it restarts itself again.
I've tried replacing the battery with a new one, also doesn't work. There is no LG service center in my city, and I have no warranty whatsoever over this phone because I bought it online. I couldn't find anyone with the same problem.
Here's a video showing you the problem:

Help guys.. What should I do and how to fix this?

G3 backlight turns off after booting.

I got an old G3 VS985. At first it seemed broken beyond fixing but then I realized the backlight turns off after the Android logo comes on. It will be on when off and charging as well. Using a flashlight, I managed to navigate the menu and factory reset. The backlight stayed off throughout the reset and I forced it to shutdown when it started setup and asked for the language because I still couldn't see. But when I turned it back on, it was working properly. However, after a while it went to sleep and when I tried to use it again it was back to the issue. I managed to boot I to the recovery menu and cleared the cache. After that, it rebooted and the screen worked again. I pressed the power button to shut the screen off and back on a few times and it still worked. I left it for a few minutes and it's back to no backlight. I was going to try and reset from the recovery menu but I was only able to get into the menu that one time for some reason. Maybe the instructions I've found are wrong but I tried a few things and can't get back to it. I also checked for updates and it said there aren't any. It's just an old phone that someone didn't want that I thought I could give to my kid to play games with, so not activated or anything. I don't know if it's a hardware issue but it doesn't seem like it because it works for a bit after reset. Any ideas? Also, how can I get into recovery mode every time?
