Hi, I don't know if this has been mentioned anywhere and yes i know the bootloop issue is a big problem but i wondered if anyone else has been semi-successful like me. First off the other day my phone rebooted and ended up in a bootloop except the screen never goes completely blank it just dims and comes back on. I did a hard reset and it starts working again for a few days. Then when i connect to wifi it will reboot all of a sudden and be fine until it reboots again and i have to hard reset for another few days. sometimes when looping it will get to the updating apps screen then when it finishes it loops again.
Is this the standard bootloop or does it seem like something different?
Sorry if this is just another repeat of an old issue it just seems to be slightly different from what i have read about the bootloop caused by the known hardware issue. Also the first 3 digits of the serial are 507 if this helps.

Maybe yours is jut preparing for proper bootloop maybe the pins on the bigger qualcomm chip still connect to the motherboard from time to time so you manage to get it booting. Though I wouldn't call it a working device so I would suggest you to start working with LG to have it fixed.

flash stock firmware and then try it for weeks if it happens then hardware is damaged..

Dont play around with it too much it might get permanently bricked ur best option now is to flash a lollipop kdz root it then apply the disable core method to working it again ofcourse the phone will be slow ...or u could just send it to lg for replacement or repair...check youtube for disable core method for g4
I have just plugged it into Lg bridge and run the update error recovery. It hasn't rebooted when connecting to wifi yet but if it does I'm just going to phone LG to sort out a repair and buy a temp phone to use while that happens. I just don't want to do anything that could affect warranty although usually, the warranty would be out the window on day 1 with me
It just seems weird that every time I have seen it reboot it was when it connected to wifi.

Ok here's the deal, I have my device about 3 months and never had a problem. Since last week my phone kept turning off when I'm on the home screen, restarts when screen is off. So I was advice to try and hard reset my device which I did bunch of times and problems still continues. I did not install any apps when I hard reset it and I don't know what to do????

Random restarting can happen with custom ROMs. It's happened to me with CM a while back. With you being on a custom ROM, that may be what is causing your issue.
Only way to really determine the cause is to view your logcat, which is tricky because it is cleared on a reboot. This app: aLogcat (free) might be useful. You can set it to save your logcats to your sdcard in intervals, that way it is persistant through a reboot.
You can monitor that and see what exactly is causing your issue.
You can also flash back to stock and see if the issue persists.
If you are running stock rom then your main board might be going bad. Someone sent me an article the other day about this happening to people. Apparently Samsung fixes it for free.

Hello everyone! I own a Galaxy Nexus that's running one of the Cyanogenmod 4.4 snapshots. While watching a youtube video my phone froze up and shut itself off. I rebooted and after a few moments the same thing happened. When I power up my phone one of two things happen. It either reboots while booting and automatically attempts to boot again or it manages to turn on for a short while and then turns itself off.
I believed the issue was a battery or hardware one at first but after leaving my phone booted in recovery for half an hour with no ill effects I think something else might be up. What do you guys think is the best course of action? The only thing I've done is a factory reset that has done nothing.
Anyone?

Factory Reset and reflash the rom. If that doesn't work try flashing another rom like Vanir. If your phone still shuts off...well unfortunately this may be a hardware related issue, nothing you can do if that's the case. Unless it's your battery which I highly doubt.
I think it's the same thing that happened to me a year ago, check this out:
http://forum.xda-developers.com/galaxy-nexus/help/bricked-phone-t2306672
for me it was a hw related problem, i had to send the phone back to assistance and have it repaired (it was still under warranty).
Good luck :good:
Thank you all for your ideas. I'll report back my findings later today.
Same problem over here. Tried a lot of roms (custom and stock from Google page), took it to assistance (no warranty though) was told is a hardware issue. Since replacing the mainboard its the same price as a new phone... well you know.
But a curios thing happened: tried to flash the Ubuntu Touch rom, same problem (reboots at Ubuntu start screen) and the Firefox-OS, that one worked (considering it's limitations obviously)!
Few days ago my phone began to shutdown either immediately or after a short freeze of the system. This happens in many situations, although mostly outside/when I'm on the move (I tried disabling GPS but it didn't help). Usually when I switch it on again it either shutdowns just as the lockscreen appears or doesn't work at all until I remove the battery for at least 10 seconds. The latter sometimes helps and the phone works properly for a couple of hours and the whole thing start over. I tried clearing cache, restoring factory defaults, changing the software completely (Fullmics, LineageOS) but nothing helps. I made sure that this is NOT battery related - I have a spare one and it's all the same.
I'm not sure whether the issue is hardware or software related. Here are my suspicions:
Why it might be a software issue:
- Just before the phone shut down for the first time I noticed that the upper part of the display stopped working - I simply could not pull down the notification bar. I rotated the screen and noticed that the same thing happens to the menu buttons which obviously replaced notification bar in the upper part of the screen. Eventually it turned out that this is not a defect of the screen and that part of the screen simply froze. After reboot it worked normally for a while and then froze again. After changing the software the problem seems to be gone.
- When I'm in recovery mode (TWRP) the phone usually is stable, it shut down only once or twice
Reasons for hardware:
- For a couple of months now the Wi-Fi is not working properly. It disconnects and whenever I try to reestablish the connection it goes into "Saved->Connecting->Saved". Maybe this is just the next step towards the graveyard?
- It's about 6 months since the warranty has expired
Have you experienced this and/or have any idea what's going on?
EDIT: With time it was more and more difficult to turn the phone on and keep it running and right now it's not turning on at all.
EDIT 2: I made it run again. TWRP works perfectly but once I reboot to System it shuts down almost immediately.
Nobody has any idea?
I'd guess it's the battery.
When I bought my G3 in Oct 2015, I had random reboots aswell, nothing helped (turning off mediascan, restore kdz via LGFlashtool 2014 etc.).
So I went ahead and bought another battery (7000mha) from ebay.
Never again suffered from those annoying random reboots
(Inserting the old battery, makes the reboots reappear, so that is postivie proof for the battery thesis).

As I wrote above, I have two batteries and the problems exists with both of them.
In that case try this:
https://forum.xda-developers.com/lg-g3/general/g3-hardware-problems-solved-bsod-screen-t3597086
Regarding your battery: You didn't only get "original" batteries ? I have a third party one... All original ones I had so far failed me...
Hi guys. A relative asked me if i can repair his note 2. I think his network was locked and the phone keeps restarting everytime. I flashed a new firmware on the phone. The one I use on mine..XXUFNG1, and also I went into recovery and clear data and cache after flashing. But still the phone keeps rebooting everytime. Why is that and how can I fix this?
Note : It's not bootloop or anything. You can switch on the phone, use it for like 5mins and then it freezes and restarts itself. And it goes on like that. Sometimes it doesn't restart also and you can use for more. But most of the time after 5mins, it restarts.

Everything stock..like I said! Before flashing to the newest rom too, everything was stock.
Was the phone dropped or exposed to moisture? Possible battery problem? Reboots even when connected to a charger?

Hi..thanks for reply. I tried another battery in it. The one I use myself. But it still restarts. I don't know if the phone was dropped or anything though. The relative just told me that it needs to be unlocked. Do you think it's software related? Or something is damaged in the phone?
Since it is running a stock ROM and still behaves this way after a factory reset, I think there is a hardware problem.
I might have a similar problem. I copy from another thread:
Hey guys,
I like this rom so far. But since 2 weeks I got an issue.
My phone randomly turns off, atleast I guess that's what happens. Sometimes the "notify" LED is on permanently but the display won't go on. To start the phone again I have to put out the battery and put it back in.
My battery is randomly empty pretty fast even if I just let the phone turned off. This happens like every 5 minutes.
I already bought a new battery but the problem hasn't changed.
What to do now? :>

I like the phone. It's over 5 years old and runs like the first day. Except it DOESN'T wake up anymore after a short time when the screen is off. I can press the power/home button as many times as I want and wait for 5 minutes, screen will still be off. Only way to "wake" it up again is to put the battery out and in again.
Currently I don't have enough money to buy a new phone and I can get a new motherboard for 25$. But I'm not sure if this will fix my problem.
I'm not even sure if this is the ROMs problem since it worked with all earlier versions of this rom perfectly and even the latest release worked for weeks/months.

As long as I leave the screen turned on the display/phone won't go off and I can use it as always. Even the battery don't drop drastically then.
It might be exposed to moisture tho. When I take a hot shower I'll leave it on the window sill and the room gets steamy.
ROM: [7.1.2 r24] LineageOS for N7100 [Unofficial] - Version from 08.10.2017
GAPPS: Open Gapps ARM 7.1 Aroma - 03.05.2017
Baseband: N7100XXUFND3
Ril and other stuff I don't know where to check.
Some years ago I had the SDS and the motherboard was changed without the EMMC bug.
Sometimes my phone only charges in slow mode too.
I try a clean install and newer pico gapps now. Maybe it will solve the problem. I'll reply then if it worked or not.
[EDIT]
Since my phone was low on battery I turned it off completly and put it on the charger. After an hour or so I wanted to look after it.
The green charging light stays on and if I want to turn the phone on nothing happens. The light stays on even after removing the charger.
Seems like a hardware, not a rom problem? Will changing the motherboard fix this?
[EDIT 2]
Quick update. I fully wiped/factory resetted and clean installed newest version of this ROM + newest mini pico GApps. Still the same problem. Gonna try it with another ROM/kernel now and if the problem persists it's a hardware fault.
[EDIT 3]
Fully wiped again and changed ROM+Kernel. Still the same problem.
Hello everyon everyone.
I have the SM-P600 version, everything was good until the beginning of the week when touchpad began to go off without reason, and completely random.
I first reinstalled several official ROMs from the most recent to the oldest, with no significant improvement
Then i rooted and tried Lineage, it looked good for a while, but in the end same problem.
Please note, when the tablet begins to mess, the reboots are occuring more and more often and after a while it turns in a loop and im not even able to switch it off.
Samsung logo display, black screen, logo, black screen, etc ...
I think rather for a battery-side problem, if some people have faced similar problem, I'm taking help.
Do you know if by chance we can use the tablet without battery to test this theory?
Thank you in advance for any answers.

I think I'd be taking a close look at the physical power button. Seems to me that if it had gone flakey it could cause something like this.

Hello and thanks for you answer,
Just to precise i never faced this issue while flashing an official or custom ROM, dont know if it is just luck or it can help in anything
Anyway ill try to check it the power button just in case
It's weird I just started having this exact problem myself. One morning I unplugged it and it had shut itself down overnight. Since then it randomly reboots. Sometimes I can get 20/30 minutes out of it, but once it starts, it can get into multiple reboots with the only way to stop it is to plug in the charger. I tried wiping cashe/dalvic (no help). Nothing was recently changed (including apps). Tried resoldering battery connector (battery was replaced a year or so ago with OEM Sammy). The P600 is rooted with TWRP installed, but no custom ROM. Usually the reboots start while I'm doing something (surfing, email, etc.), but I don't think it will do it while sleeping. I'm considering the power button, but I don't see this exact problem anywhere else, but this post. Any ideas?
OK. My tablet has taken a turn for the worse. Now it is stuck in a continuous boot loop. I tried the power switch, no help. I tried booting into TWRP, and it went back into rebooting before I could do anything. Strange thing is I can put it into download mode indefinitely without it rebooting. Should I ODIN back to stock? I tried the resoldering of the battery connection earlier. Any other ideas?
