G3 backlight turns off after booting. - Verizon LG G3

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?

Touch Pro abruptly stopped working; won't boot.

So here's a peculiar incident:
I have a CDMA TP with a stock ROM and a few basic apps I gathered from these forums and others. I've had it for less than a week.
Tonite, I went to check my text messages. Suddenly, the screen went black and the phone stopped responding. After pressing the power button and fiddling with the keys, I pulled out the stylus and did a soft reset. No response. Confused by this, I tried again, but still nothing. I removed the battery, and turned the phone back on. It froze at the "Touch Pro" screen with the rom/radio/etc info at the bottom. After repeating this a few times I decided to do a hard reset. So, I turn the device on and perform the hard reset. By this point the TP is only turning on SOME TIMES, and I have to take the battery out and put it back in often just to get it to start successfully. So, I finally get the device to boot up and it starts to configure WinMo. Suddenly, while configuring, it freezes. Now I try to turn it back on, and nothing happens.
Basically the device is stuck like this, shifting between not turning on at all and turning on but freezing at the "Touch Pro" screen.
So, my question is, what the heck is going on here? Has anyone else had this problem, or does this sound familiar to anyone? Any help would be greatly, greatly appreciated.
p.s. Yes, the battery is fully charged.

Time to take it in and get a new one.....
Same problem here phone started b not coming out of lock mode. Backlight is on but no display on screen (if i tilt the screen left and right i can see light coming from behind) did about 6 hard resets and still same problem. also power button works whenever it wants to. this phone sucks @ss, i want my mogul back. on a second note my replacement will be here on wednesday.
Touch Pro stock rom purchased back in nov when it came out
yeah, i've had the same problem, i found if i hit my phone on the back or side and then batter pull and hit the soft reset while off, not the power button to turn it back on, it comes back on with color on the screen not just blank black screen with backlight, this works mostly every time, but when it doesn't, i just hold the power button down and do battery pull and hit the power button and it works, its like its got a combo of things you have to do before it works.. weird
Boot Up
I have also had similar problems. I for some reason sometimes have to remove my SD card and boot up without it for some reason. Not all the time, but every once in a blue moon. Not too sure how that affects anything, but you may try that too.
well i started a thread here ***help*** because i kinda have the same problem.
i downloaded some cabs, nothing fancy but i had some problems with a theme i downloaded. when i went to deleted i couldnt..... to make a story short, i took it to the sprint store where they tried to do a master reset/ hard reset and it wont take it. it wont do a thing... they say some important files are missing...
the phone works but not the way it should... the time on the home screen wont show up. and some other small things...
dont know how this happened but i would like to know... im worried about new programs to the phone now. ( getting a new one)
still want to see if i can fix this one.

Have you tried re flashing the ROM?
it wasnt HTC's fault for your phone's not booting...thats what happens when u try to mess with the hardware too much and you dont know what your doing
Would you want to sell???
Reboot Brick HTC process
****DOn't take battery out after hard boot***
1.just watch videohttp://www.youtube.com/watch?v=sk56olMkCtU and do what they do but dont take battery out. LEAVE phone STUCK on BOOT screen. Nothign else will move or work but you want phone just like that.
2. connect usb cable to active sync. (this may not link up but leave usb connected anyhow) Do not delete phone profile.
3.use rom like Download MightyROM6_Herman.exe avail at: http://www.lilrico.com/Mighty/mightyromblog/?p=454
4 although active sync is still attatched but may not be connecting. It will connect thru usb anyway when you run the rom software. http://www.youtube.com/watch?v=fV2I2WAFkg4&NR=1
This worked and kept phone from cutting on and off. and restored ROM. don't know about original htc boot. but your phone will work under this rom for now and you can go from there.
hey thanks plain ole dumb, it works now.
man I thought it was over.
thanks again

[Q] End key stopped working after hard reset

So by accident I launched a CHT file from my SD Card which essentially crashed sense. No biggie, did a hard reset and thought I would be okay.
Wrong.
When I hold down the end key (to either load johcos' end key or even if i uninstall it) my screen is dead. The hard keys work, but not the screen.
Anyone have a suggestion? I have been using tmo-us stock rom without problems until yesterday when this started. I realize I could flash a new rom and maybe it is time...but tis very annoying this is happening after a hard reset.
Thanks.
still not working after flashing energy rom
argh.
flashed energy.
same problem.
now have to work...but any suggestions? my long hard key is dead and freezes my phone. hard reset/ new rom did nothing.
thanks.
same with android
so now anytime my phone goes to lock screen the screen stops functioning though the hardkeys work just fine.
thought i would try android and be savvy...but wrong.
same problem.
any ideas? i am ready to take a hammer to this damn thing...
This recently happened to my GF's phone, She said she was just playing a game one day, it froze so she popped the battery out and rebooted. Now every time she uses the End/Power ( red ) hard button to shutoff or wake up the device, the screen stays locked and won't respond.
I have tried soft reset, hard reset, different lock screens and what not. The only solution I found, besides sending it in, is to let the screen shut off by itself, and then wake it up with the Call/Send ( green ) hard button.
You can also try using the End/Power hard button to lock it, but then as long as you wake it with the Call/Send hard button it should be fine.
It has worked every time now. Try it and see if it helps! It's a little annoying but it saves money and insurance!
Going to repost this in all those previous listed threads to see if it helps anyone else.
Good Luck!

Cannot get device to factory reset

I posted this in the A500 forum as well, but it's probable that this is not a problem limited to my device, and it's also possible that there is a rom that might help me out.
I purchased my tablet on the day it came out, so it's long out of warranty. Everything has been fine with it until three nights ago.
I woke up in the morning to a crashed app alert. I don't get crashed apps often, but it does happen, so I hit ok. A few seconds later I was inundated with crashed app alerts. At that point, any app I opened would also crash immediately. Figuring a good reset would fix it, I turned it off...and it wouldn't turn back on.
I did finally get it to start by holding the volume up and power button.
But that didn't fix the problem. I've discovered that it is somewhat stable if I keep wifi off, but if wifi is on, within minutes everything starts to crash again.
I tried uninstalling some of the apps that crash, but when I restart, the apps are back. It doesn't matter what I uninstall, when I restart, it's back. Installed apps also disappear, the wallpaper resets...basically nothing I do sticks once I restart. I tried to factory reset using the button combination required for my device, and the screen gives the "erasing user data" message, but when it loads up, everything is just as I left it. I tried using the android os option to factory reset, but when I hit "erase everything", the button depresses, but nothing happens.
So obviously, I'm a bit perplexed.
I've never rooted it, and I ran an anti-virus scan a few hours before this all happened and it came up clean.
Anyone ever experienced this? Any advice? If no one has any ideas one how to fix it, is there a way to bypass the main os completely with a rom? I have absolutely no idea how those work, so it may be obvious that it won't, but I figured I'd check.
Thanks in advance! And thanks for reading this far, even if you have no advice!

LG Optimus F6 Possible reset?

Hi this is my first thread and also an emergency but any help much appreciated!
My Optimus F6 had this problem every few months but it usually fixes itself, where it gets caught in a boot loop and the MetroPCS logo would keep repeating on startup without going to home screen. The last time it happened a couple months ago it was also shutting down really fast without me doing anythingwhen it did work , so it most likely thought power was being held when it wasn't. I fixed it be blowing into the buttons and pressing them while the phone was off. I also removed the battery/sim card a lot.
Anyway today it went into the boot loop again...so I held the volume keys and the home button before turning it on, and it went into what I assumed was the recovery menu. Now this couldnt have been more than a couple seconds, but I was looked at the choices, and then it acted if I had pressed a key...and then it said "Error" unable to something something...regardless though I pulled out the battery immediately, this all happened very quickly. Now the phone boots fine but I'm getting the startup wizard as if it had reset. Now when I try the Recovery Menu again the choices seem normal now, so I maybe accessed a different menu before. I called LG and no help, I really need to know if the phone has been reset or not?
I have to go to work in a couple days and the thought of all my critical data being lost and my contacts and photos and memos on internal memory gone is gonna be really bad, I have no way to get some of the stuff back. Please help! Thank you!

Why don't you go through the start up wizard without logging in to anything and see? If it has been reset, I hope you had it set to back up your data to Google or some other cloud service or you're out of luck if it was not saved on an external SD card.
I would but I'm afraid if I go further through the Startup Wizard it'll further erase and chance I have of getting my data

It's either gone or not already. Going through the Startup Wizard has no effect on that.

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?
