So the other day I let my n7 die completely, which has happened in the past. Today I went to charge it with my computer and turn it on, so I plugged it into my laptop's USB port. For reference, I just installed Windows 8 and there are no android drivers on my laptop. Anyway, I plug it in and hold the power button and it shows me the google screen, then it goes to a black screen annnndddddddd.... Nothing. It stayed there until I did a hard kill. I can get to the bootloader as well as TWRP. Within TWRP I cleared the caches, and ran a fix permissions. Nothing. I've backed up in TWRP and have yet to wipe my data because that's a last resort for me at this point. Right now its sitting on the charger. When I plug it in I get the battery thing as well as the battery charging thing, however after the battery charging thing goes away I can't call it back up. (usually it'll go away but you can hit the power button and it will come back).
This appears to be a hard brick but I'm not sure. I was running 4.4.2 stock, rooted, bootloader unlocked, with Gravity Box, but that's it. Otherwise I've been running normal user stuff and it has been (up until now) just fine, normal battery life and everything.

I fixed it. Something happened between the battery draining completely and me trying to turn it on that was causing a /system mount failure, thus the black screen after the bootloader. Here's how I fixed it:
I downloaded the full restore zip from Google (Mine was KOT49H at the time of posting this).
Then I opened the package, and the second package within the first one. I extraced the system.img file to my desktop.
After extracting the system.img file, I used fastboot on my computer to flash the system in my bootloader, and now its back to normal. No data was lost, nothing broken. I re rooted and everything seems to be in working order.
Good job! I know none of my 1st gen N7's liked to be drained completely so I make a big effort not to. Phones don't seem to have issues like these tablets sometimes do.

Hello,
So I bought a G3 the day before yesterday and yesterday was my first day with it, and for that first day my phone had shutdown twice on its own. The first time was when my phone was lying on the bed and doing nothing, it had around 50% battery and was not hot or anything.
The second time was this night i don't know when, i have put my G3 on the charger and went to sleep i woke up and it had shutdown.
I didn't made factory reset when i got i from the box which i will when i come home from work and hopefully this will fix it, but does anyone have a problem like that? If is something serious i will be disappointed to return the phone.
p.s. My previous phone was galaxy s2 and had this king of problem only with custom roms and kernels, but i have not put anything on the G3 yet, except activating the developers options and had switched it to ART and the first time the phone had shutdown i thought that the art was the issue and switched it back to dalvik, the second time though was on dalvik.

I have the exact same problem. The past few days when I go to bed and wake up in the morning, the phone has shut itself off. I haven't rooted or installed any custom roms.
I would advise you both to take a factory reset, only install apps you need for a few days and see if the problem persists, if it doesn't install your apps back one by one as it may well be a particular app causing the reboots.
If you still get reboots after the reset and with no apps installed then you may have to take the phone back to swap it.

Yes as I said in the first post the factory format and hard reset will be the first thing that will be done as soon I am at home. About the apps i have pretty much basic apps (facebook, messenger, soundcloud, etc) all from the market except smashhit of which i have the apk and installed from the internal memory.
Except those apps I have 2 mp3s and some wallpapers and nothing else, becouse when i got my phone it was late on the evening and i had no time to do anything else. So the phone is pretty much out off the box and I was verry frustrated when the secound shutdown happened, becouse i tought the first was from the ART runtime.
Anyway today I will have more time to spend on the phone and we will see what will happend.
p.s. The phone does not reboots, just shuts off.

Is it definitely off or is the phone just stuck on a black screen? It is quite common on some devices when something is not quite right for the kernel to be unable to wake the phone up, the phone is still technically on but stuck in deep sleep.
does holding the power button for 2 seconds turn it on? or do you have to hold it for say 7-8 seconds?

It is definetly shut down around 2 seconds(the normal time to hold the power button to turn on) it turns on and work perfectly and does not show anything suspicious in its behavior, it's super fast, not laggy and etc, may be a little high on ram consumptions but with this havy skin i think it is normal or could not be normal idk, the ram consumptions go from about 1,2GB the lowest i have seen to up to 2,3 the highes i have seen.
Anyway about the shut off think yes defenetly 100% sure it is off, it happend again a while ago and i thoght the same thing may be it si deep asleep even i had chacked the weather 10 min ago and call myself from a friends phone and the operator said that the phone is off or i am somewhere without network covarage.
i got same problem. it turn off it selft and black screen even battery still 70%. rmust remove the battery to restart again, ealy bad. huft

If you have to remove the battery to get it to restart then its not actually shut off, its just stuck in deep sleep! which is usually caused by a bad app.
Yes if you have to remove the battery the problem is different, i just have to push the power button and it boots right away after it have shuted off by its self........
i didnt have this issue with my 855. but i did a factory reset after i got the phone just for the hell of it
So it's reset time i finally have some time to the some staff on the phone so hopefully everything will be fine. I will post if this fix or not the problem to inform the other people in this thread.

did you have any luck with the problem? I have the same issue, performed a factory reset and restored, hopefully it will fix too..
Hi all!
I have and have had the same problem and think I've pinpointed the problem to Google Search but can't 100% confirm it yet. I didn't do a factory reset when I got the phone and it shutdown during the night. I did a factory reset, made sure it got enough time to update everything properly. Problem was gone and worked fine. HOWEVER, the phone kept asking me which home screen I prefer at random times when I hit the home button. With random I mean like 4+ times per day. I searched the net and found a threat saying that a guy with a G2 solved the problem by removing Google Search updates. So I decided to do just that and get the factory version back and the questions disappeared but guess what, the phone shut down the following night.
Any takers or might this just be random? Note that it was working fine for three days with the updated Google Search and shutdown the first night after the downgrade.
So I did hard reset and so far so good the phone had not shutted down itself, and I updated everything which need to be updated (mentioning this for the guy with the upper post). So far so good I will keep you in touch if something goes bad...

The problem will be resolved?
I suggest take it to your dealer and get it replaced asap. I've seen lots of returned phones(my job at XXXXXXX company ) with the same issue, and as long as the defect is reproducible the dealer will give you a new phone. If it's outa replacement period then they'll probably repair it.
aaaaaaaaaaaaaaaaaaaaand shut down again but this time it took quite a bit time longer to shut off by its self so i tought the problem was fixed, but it's not, so i am going to the store which i buy it from to replace the device.....
Does this also happen with the korean models?
Hi all,
recently my D855 with v20T (root/xposed) started to sort of randomly reboot. It seems like once the device gets too hot, it's gone.
Happens rarely during general usage, often while playing a game, and especially often when starting the camera.
But it behaves strangely in general: if I do *not* unlock the SIM (and thus can't use the phone), the device runs forever, without a reboot, no matter what the device temperature is. Same for recovery (TWRP), it can stay there for hours and heat up however it likes, no reboot.
Removing the SIM and/or microSD does not make a difference, battery level does not matter.
I pulled a backup of the stock ROM, wiped everything (system, data, cache, dalvik) and flashed Fulmics 5.
Unlocking worked once or twice, the next time I entered my SIM pin, the lock screen showed, then reboot. This behaviour (unlock SIM, reboot) repeats endlessly. If I leave it turned off for 10-15 minutes - or sitting at the SIM unlock screen - it most of the time works fine after unlocking.
Wiped again, flashed robalm's v30F ROM.
Guess what, exactly the same.
On both variants, the phone got rather hot during the "optimizing app x of 190" screen, but never rebooted, only after I unlocked the SIM.
Let it sit overnight on the unlock screen, no reboot at all. Unlocked this morning, added my google account, rebooted - same thing again.
It's starting to drive me crazy, now it froze right in the middle of setting up the google account after another clean flash.
Is the phone prone for repair, or can anyone think of another solution to this weird issue?
Edit: Fun fact: if I manage to do the lock screen swipe before the SIM lock screen comes up, the phone reboots instantly as well.
Edit2: Followed the instructions from this thread to go back to completely stock v20T. Rebooted after optimizing apps before I could even choose a language, ran seemingly fine after this, started bootlooping after the first manual reboot. A full wipe later (volDn+Power) it at least boots. What the hell?
Thank you and best regards,
Sub
I have similar problem. Cant connect issue with exact cause, but it restarts almost every few minutes of use. Camera launch causes restart almost immediately. Phone is unusable. My VolDn button is not working so I'm currently a bit afraid to try anything new... I updated from Fulmics4.1 (i havent got reboot problems since last 1,5week ago) to 5.1 but issue persists even after full wipe. Seriously dont know what to think about it.
At first I thought that reboots are caused by low power (much more frequent with battery under 30%), then maybe big cpu load or high brightness.... now basically everything causes reboots. Im really annoyed this phone been crap since day one...
I havent tried your sim unclocking method as my doesnt have pin security etc. Let me know if you will find out solution.

Just received the device back from LG, they replaced the mainboard, even got a new IMEI and v30c preinstalled.
It is the same case, with the protective glass on top and a dent on the left plus the 2-3 micro-cracks around the frame.
Not sure if they swapped the battery. The problem showed up again with anywhere between 50 and 15 percent battery left.
Unfortunately I only tested it after leaving the shop, after a long walk to the bus which I caught just in time.
Setup assistant completed -> reboot.
Google setup nearly completed -> reboot.
Removed SIM and MicroSD, started phone, started camera, made a movie -> reboot.
Wiped again (strange enough, v30c only has 61 applications to optimize while v20* has 190+?), tried again, same thing.
Next, after letting the back camera take a movie for 2-3 minutes, I wanted to adjust display brightness to the max.
Result: see screenshot. This also happened with the cable plugged in.
I will return it for repair once more tomorrow...
Anyway, thank you for your answers

It's a common thing if you use camera specially if you take video in 4k mode your phone heat up and you can't use full brightness in stock rom it's a feature try moded thermal config...also try new battery if battery percentage suddenly dropped it seems battery issue because i face the same problem....

I used to have thermals installed, the 75 dregrees Celsius variant, iirc.
Everything else was at stock, except for one short excursion to CM12 and one to ... some custom ROM.
Think I never actually took 4k videos, and the first 1,5 years the phone got a bit warmer but never really hot. Only recently it started to get really hot especially when using the camera, this also consistently was what could cause the reboot loops for sure. Other candidates were a few games which use more processing power like Alto's Adventure.
The battery drops by 2-3% after a reboot, because of the load the phone has (and the heat it develops during boot).
Anyway, I added the screenshot to the next repair request, and the woman at the counter said they'd look into the battery specifically (it seems to give out too much voltage, she said), but also check everything else once more.
I'll let them repair up to three times, then ask for a replacement, should be legal within 2 years after purchase in Germany.
Also, next time I'll take the 15 minutes (before doing a 1h/direction trip) to factory reset the phone, set it up and start the camera. If it reboots during any of this -> return, repeat.

Received my phone back from LG, finally.
Battery's broken - it outputs too much power.
Ordered a new battery and just put it in, so far no reboots during setup.
At least this got me a new mainboard and new IMEI

Hahahahahahahahaha
I just wondered why the phone shows 25 GB free everywhere, even without SD.
Turns out, during repair instead of replacing the 16GB/2GB board with an identical one, they installed the 32GB/3GB board

Hello there. I have to write this again becuase the last topic I wrote didnt get posted...
I have a big problem with my G3 and I have tried everything I could but nothing helped so I hope you can help me.
First of all my phone is only stock. I didnt try rooting it or installing custom roms on it.
Heres the whole story of what happened:
A week ago my phone started to act strangely. When I tried turning the wifi off it restarted or froze for a bit and then went on normaly as if nothing happened. I didnt even have to input my pin. Then one day I got home and the phone simply started reseting itself constantly. Always loaded up to the pin screen but I didnt even have time to input the pin and it reset it self again. This went on for like 15 reset before I lost patience and pulled the battery which didnt help at all since after being turned back on it went back to the reseting. I found online that it was probably a battery problem but I was impatient (shipping to my country is over 2 weeks and buying a battery in stores here costs twice the normal price of a genuine battery but only for a "fake" battery) so I factory reseted it via power button+volume down. After that it worked normally but I lost all my data.
The day after this I spilled ice tea on the phone. I opened it, cleaned it and let it dry out. Turned it on after an hour of drying and it worked but after maybe 2 hours it began freezing. When I tapped on the screen it didnt react, when I pressed the power button it took more then 10 seconds to react to it. It turned on, didnt react to touch and then in mere seconds it went dark and then turned off. I couldnt even unlock the screen. Tried pulling the battery but then it wouldnt even turn on. It stayed on the LG logo. I left it on the logo and on the charger and after an hour or so it turned on and worked normally so I took it apart and cleaned it once more even under the screws and such and it worked after that. Until today.
The freezing problem returned. I was playing a game on it and chatting via messenger when the phone stopped reacting. I had signal, wifi, I got new notifications and basically everything on it worked but the screen didnt react to touch and when pressing the power button it took over 10 seconds to light up the screen, then it went darker and then it shut down. Couldnt do anything. After I pulled the battery it would get stuck in a boot loop for maybe 10-15 minutes and then load but the phone couldnt be used. Just as before the screen turned on with a delay but no reaction to touch whatsoever.
I tried factory reset, downgrading to a lower android version (from 6 to 4) with LGUP and lg flash tool, and I bought a new battery. Nothing worked. I managed to get it to android 4 but that didnt help either. I though it was a problem with 6 because the problem started after the update, before that I didnt have a single problem with my phone.
Now its in a state where it doesnt work. The phone is running, apps are upgrading after the factory reset and all that but I cant do anything with it. Once in a while it will work normally as if nothing but that is rare.
Could you please help ? I love this phone and I dont want to have to sell it for spare parts.
EDIT: I left the phone running to see what would happen an after several hours an error message appeared saying "Process system isnt responding". After pressing ok it worked fine. How can I fix this. I googled it but all I found was a problem with sd card (none is inside), with battery (I have a new one) and with rooting (mines not rooted).
Hello,
This is what have happened:
I was browsing via Chrome, when phone froze. Well, no big deal. It went black, and I couldn't power it back on. I was on rehersal, so I left it on the table for an hour.
Came back to it, tried to power it on, and after 20sec or so of holding Power button, Google appeared. And it disapeared again.
And that is it.
I can access bootloader, and recovery.
From there I tried to flash fresh img, but my device is locked. Went the other way. I downloaded latest OTA and went to adb sideload, and it downloaded it all to phone, but same thing with booting. It stops.
Sometimes it even goes to those circle animations on booting, but than it freezes again, and turns off.
Any hope for my 2 years friend now
Thanks.
@Nuuq: by searching for 'brick' 'bootloop' you find for example this thread Hope, it helps.
Exact same thing happened to me this morning. I was playing Clash Royale, and it froze. Rebooted, and it just went to Google screen and nothing else. I let it sit for an hour, and it started to boot, but froze mid-boot-animation. I can get into bootloader and recovery, so I'm going to flash the Bootloop fix this afternoon and see if it fixes it.
Odd......
I thought this was a CPU bootloop issue, so I flashed the 4-core TWRP, wiped everything, and installed the stock OPR4.170623.006 system, vendor, and thne 4-core boot.img I found in the bootloop thread. I got a little farther, say 5 minutes instead of 5 seconds, but it was still crashing and bootlooping! I couldn't activate the phone, cuz it was rebooting while waiting for my 2-factor authentication text, and when I tried wiping it again, it was rebooting while in TWRP while re-flashing the system. The more I try to fix it, the worse it gets...
I may just give up on the phone, and contact Project Fi support to see if they'll give me a new one.
Same here guys...put inside the the fridge for about an hour and it started, just in time to save my photos on Google photo...but as soon as I start to use it, it freeze, turn off, no reboot. If I reboot, it freezes on circles Google animation...i can enter in bootloader and recovery too...any suggestion?
Same problem - merrily browsing -> crashed and now bootlooping - can get to the bootloader menu but can't get into recovery mode
Running Oreo 8.0
I flashed the 4-core TWRP, and it was crashing even in that. Last night, it sat for 3 hours on the activation page, and never froze, but anytime I try to use it, it freezes. It sometimes turns on, but most of the time it just crashes while booting.
I already use Google Photos, and my texts are synced through Fi hangouts, so I'm not worried about losing anything. I've wiped my phone and started over maybe a dozen times over the past year. Different ROMs, kernels, etc. I just want a working device.
I called Google, and they said nope. They want me to call LG, but my brother has had 2 bootlooping 5x, and LG didn't help with either of his. I doubt LG will help me here, cuz I bought it from the Google Store. I think I have 3 options:
1) pay to gave the CPU reflowed. If I went this route, I would want to upgrade to 3GB or 4GB of RAM at the same time. If I do this, I still have to deal with my battery only holding a 70% of it's charge, and not wanting to spend $50 on a 2 year old OEM batter.
2) Upgrade to a used Pixel. I'm sure with the Pixel 2 coming out, lots of people are going to be upgrading, and I'm sure there will be a bunch of used Pixels showing up. But, you're still buying a used phone that's been out for a year now...
3) Upgrade to the Android One Moto X4. The word "upgrade' is used loosely, as it's VERY similar to our 5Xs. Similar benchmarks, similar screens, similar primary cameras, almost the exact same dimensions, etc. It would be an upgrade with 3GB RAM, bigger storage, SD card slot, 2nd rear camera, better GPS, bigger battery, new (not used), and a few other minor tweaks. Con is that it's so new, there are no ROM/kernels for it yet
I think I just talked myself into a X4 while writing this. We'll see what the wife says.
it happen for me but me i can boot to bootloder but the phone become very slow i just escape from bootloop i turn it on and after 2 week he bootloop again now only fastboot no recovery and no system how i do

Hmm, putting it in the freezer gets it to boot but rapidly crashes again - looks like it is the hardware rather than software
