About a few months ago, my lgg3 started restarting randomly (usually if I dropped it), but I never really paid attention to it. Then bout a week ago, my phone would freeze, then restart but not fully turn on (would turn off after logo appeared) and I would have to remove the battery to get it on and running normally again. Then a couple days ago, it started to not turn on at all and when I looked up what might be the problem, I figured it was probably a battery issue. So I bought a new battery and put it in, and it started to boot up but would still turn off after the logo screen. I have tried to hard reset it twice but when ever I press 'yes' to the reset, it would go to logo then turn off. I'm thinking I just need to get a new phone, as it is nearing 3 years old, but I figured I come here just to see if I can get any solutions.
Test your device with the charger plugged on, if the problem persists, it is not battery problem and maybe your motherboard has some issues.

Firstly I have to mention, that I don't regularly use my One X anymore, but I took it to Italy when I went there for holidays two weeks ago to use it as a hotspot for my HTC One and Macbook.
It was working just fine until 3 days ago, the day I flew home. During my last night the phone started rebooting every 10-20 minutes, until the battery was dead. Now that I'm back home I charged the phone and turned it back on, but it is still acting strange. I just put it on my table and realized the screen was turning on randomly and turning off again after the normal timeout. This happened again and again and after a few times the phone turned itself off and back on. This whole procedure happens over and over again in a loop.
Therefore I performed a hard reset, but the problem is still the same. Even if I turn the device off completely, it comes back to life automatically after just a few minutes. I have no idea what I should do with it, except waiting for the battery to die.
Has anyone had this problem before and knows how to fix it? I hope it's not a hardware defect, as I really like the One X as a backup phone.
Cheers,
Jake
Sounds like you need to change the power key + flex.
Hi guys, seems i never learn my lesson on backing up.
Well my g3 had died a few times on me, each time getting progressively worse. Last time i ended up replacing the battery and it was fine.
This time i was just using my phone and it died. Then wouldnt turn on. Battery was atleast 80% but still thats the first thing i did. Ran out and bought a new battery but still the same issue.
Tried everything listed including trying to get into the hard reset menu, but i get no response from the phone, not even a light. Tried the battery out and start button on for min then plug in charger or battery and still the same (no response).
Ok left it over night and the next day i tried plugging it in without the battery, it switched on and complained about the battery. SWEET !! so i plug in the battery and then pressed the on button. Phone loaded up after what i thought was a loop in the boot up but then the main screen wouldnt respond. No response to buttons, swipe (no password) or double tap.
So i tried restarting the phone. Back to the old problem.
Tried this again this morning after leaving it without battery in over night i got the same response but didnt get as far before the phone died itself.
Any ideas what to try next ? If not would anyone know how i can buy a working one and get the data off this one (if possible) as i have quite a few shots of my little one i would like to get off.
thanks in advance.
Hi,
I was browsing the web on my G4 earlier today when the screen just turned black, tried turning it back on but nothing happened then my smart watch brief to say it had lost connection to my phone so presumably it had switched off.
Been trying for the last hour or so to stay it up again but nothing works. I've tried holding the power button for 30-60 seconds, pulling the battery, charging it but no joy.
The battery was around 85% charged when this all happened and when I plug the phone into a power source the LED doesn't come on so it doesn't even look like it's drawing power.
Any ideas on what has gone wrong or how to fix?
Thanks
Having the exact same issue (Sprint Variant). Phone was fine, stock/unrooted, sitting on my desk with 80%+ battery. Checked on phone 10 minutes later, never turned back on or responds to charging.
Errr, mine as well.
Change the battery and try a factory reset but nothing change.
My girlfriend's g4 had this three weeks ago, nothing worked to get it to switch back on. She had to send it to LG for repair and it came back today saying they had replaced a faulty main board. Her g4's serial number started with 505.
What do yours start with because I know of at least 3 others that have had the same thing happen over the last month, all after a out nine months of purchasing the phone.
Try the freezer method maybe you can then backup your data at least.
Serial starting with 5xx?

Hello i am having the same issue, i don't have warranty but im still waiting for LGs response. anyone knows how to fix it permanently?
Hello,
I am having the same issue. Kindly help to solve this issue instead of changing the motherboard. :crying:
I have a N5X, unrooted, bootloader locked, 7.1.2 stock. It happened twice in the last week, the phone used to work perfectly before that. I just pick it up as usual but it doesn't turn on anymore, I tried multiple times to boot it normally or in bootloader mode but nothing happened; then the next morning I plug it into the wall the led flashes red and it reboots normally. I thought it could only happen once but it happened again yesterday night and as usual this morning it booted up. Does anybody know what the problem may be caused by? What can I do? The phone still has warranty and if no solution is found I'll send it back to Google. Sorry for my english.
I have had the exact same problem, mine only occurs when the phone is ran down to 0% and powered off. I never let that happen but I have a 3 year old son who repeatedly does it, and every time i hold my breath, praying it will come back on. Well i am holding my breath and praying once again this morning,hoping it will power back on. Do you think it could be some kind of "protected mode"to keep the battery or something else from overheating or whatever?

If you need the phone and are confident, try unlocking the bootloader, reflashing stock factory image and relocking the bootloader again. You will lose all the data, though.
If you can live without a phone for a while, just send it to Google/LG. Nothing else one can do imho.
When my phone was in the last steps of dying (eventual bootloop), I could disconnect the battery and it'd get farther through the boot cycle, or even once booted. Basically, after it wouldn't react to any buttons or combos, I would disconnected and reconnected the battery. Then I could give things another shot. So I'd start it, it'd make it to the colored circles, or I could boot to the recovery menu, and try some things, but at some point it would go black. Then it would not react to anything unless I disconnected the battery. Then it would react to the buttons again and eventually one of the steps would make it go black. And then take a disconnect to get another try.
It sounds like your phone may be close to dying.
By the way, I only opened it up since I was past the warranty expiration date, and LG extending the warranty to about 18 months wasn't a known thing at the time. It is actually easy to get everything apart, but hard not to make dings in the plastic cover even using plastic tools.
I would say, back up everything you can from it and expect it is going to get worse. Redoing the OS didn't save mine.
I have a LG G3 D851 from T-Mobile. I had it from about two years now. It upgraded to Android M about a year ago and now the phone won't charge or turn on. I tried everything. First I tried to hard reset' but nothing. Next I tried refrigeration. The phone would start up and go to homescreen, but then freeze and shut off. I even bought a new battery, but it would still have the same problem. Sometimes tne phone would start and shiw that screen on but nothing on it, and it would also turn on and turn off then show the led flash red and blue. When I charge it, it would show the battery loading up and shut down, then the phone would keep restarting. Like I said, tried every thing. If anyone could help me that would be great.
Thanks

I would start with replacing the battery. It has been a wbile since i have had a g3 but this was a common issue. The batteries were known to bassicly just keel out
The solution is a simple one.
1 remove battery
2 connect charging cable (I am not kidding)
3 power in the phone
4 the phone will try to boot
5 it will fail to boot or maybe it will boot
6 insert battery while the charging cable is still attached
7 power the phone
8 the phone will boot and show 100% battery
9 reboot phone
The next video shows my phone working without the battery...
