I was given this Nexus to attempt to fix because it constantly reboots almost as soon as the lockscreen appears. I have tried a factory reset through the recovery and flashing a stock image using the Android Toolkit but the phone still just auto reboots shortly after starting. I am assuming it is having hardware failure somehow? I had no way to check the build number since I cannot access it fast enough and the device did not have USB debugging enabled so I just flashed each stock image I saw for the Verizon Toro with bootloader PRIMELC03 and so far I have not had any luck. The gallery force closes as soon as the system boots but then it will restart right after.
e: At the moment I am going to accept this as some type of hardware failure due to if I do not attempt to interact with the phone it will stay on the phone setup screen but as soon as I touch the screen it'll re-notify me of the Camera and/or Gallery crashing then restart.
ee: The phone has not rebooted for going on 30 minutes since removing the camera and software I'm going to assume that was the cause of the rebooting.
So I am keen on how to fix bootloops and going back to stock/rooting, etc...
My friend asked me if I could fix his phone for him, so I said why not. Thing is, it's the weirdest problem I ever faced with a phone, EVER.
The problem is the phone boots normally, I unlock the pattern, some seconds later it turns off and reboots. So I said hey why not boot into safe mode, perhaps it's an app causing all of this, so I did, worked perfectly, turns out "Google Play Services" was "forcing close" and suddenly phone turns off. I uninstalled all updates, cleared data, cache, everything and installed EVERY SINGLE APP on the phone and removed pattern, then rebooted phone. BUT, when i rebooted, the pattern was back, language was back to arabic (I changed it to english when in safe mode), ALL APPS were back, and the updates to Google Play Services were back. It's like I didn't do anything. So I said before it turns off I'm goin to try 1 thing, so I immediately went into settings and managed to uninstall updates for Google Play Services and cleared cache data, even to all google apps, and then I re-uninstalled all applications (out of safe mode), I thought perhaps when irebooted from safe mode, everything was back, now that I'm goin to reboot out of safe mode, this will work. So I rebooted, and guess what? EVERY SINGLE APP was back, system language back to arabic, AGAIN, and pattern was back and GPServices updates were back.
So I said hey, let's factory reset. SO I went into safe mode, I hit factory reset, phone reboots to recovery (vol up + power ) > Factory reset done > wipe cache partition done > reboot : EVERYTHING WAS THE SAME. I am completely shocked. I tried doing Factory reset out of safe mode too, same result. So I said hey, let's unlock this thing and just flash a stock rom, that'll fix it indeed. I went into fastboot and tried flashing the unlock token, the confirmation page appeared, clicked "YES", phone reboots: PATTERN AND EVERYTHING STILL THERE, while they shouldn't be since unlock performs a Factory reset, so I went back to fastboot and it indeed was NOT unlocked, I tried many times and it failed every single time I tried.
So I said hey, download AVG Antiviirus and run it perhaps it can find the problem, so I did and ran it, couldn't find anything, rebooted phone and AVG was gone. So I said, hey, again, download Google Play Services and install it on your phone, perhaps it will permanently override the one existing and it will fix the problem (it didn't, it would disappear and the old G.P.S reappear as soon as I reboot). So I said hey, you got the OTA Zip, it has the firmware, perhaps flashing that firmware will shake things up, most probably brick the phone but perhaps will let me unlock it. So I went into fastboot > fastboot oem RebootRUU > phone reboots normally, I CAN'T even access RebootRUU.
So as you can see I probably tried everything one can do in this situation.
My brothers Galaxy Nexus crashed two days ago and rebooted. Since than whenever you boot it again, it boots normally but after about 10 seconds crashes and reboots again. No matter if you unlock it, SIM installed or not, with external power or not makes no difference. Always keeps crashing and rebooting. So the first thing I did was a factory reset within the bootloader. When it restarted nothing was wiped. Wallpaper, unlock code and all apps were still there.
Weird.
So I decided to flash the the whole stock image again. Downloaded the latest version from Google and flashed it. Took a fairly long time (30 minutes), but had no errors or irregularities and had the same result as the factory reset -> nothing. Everything is still there.
How can this even be? The only thing I could imagine is a broke storage. Is this a possibility?
Thanks in advance
It might be a broken storage. One thing you can try is to flash an older version than upgrade via OTA. Assuming that you have 4.3, you can flash 4.2.2 than via OTA, you can update. I had a rebooting problem before, but it was because of my battery. When I unlocked my bootloader I was surprised to see that my data was still there but when I factory reseted, it was gone.

Hi All, i was hoping to use my old galaxy alpha as a second phone, but , since entering an unlock code from the provider, my phone is constantly restarting after 20-30 seconds. It doesnt restart when i'm in the boot menu, so i'm assuming this is a software issue.
Can i reinstall android (or even an updated version) to fix this?
This update became available to me last Saturday. I thought it was the April security patch, but after installing the update version stayed on March, I and now I get random reboots and sometime my phone will ask me to input the pattern on lockscreen, not allowing me to use my fingerprint, even if I had done it once.
Anyone else having these issues?
If the phone restarts (or soft reboots) you will not be able to use the finger print sensor until you have entered your pin in first
You may have not noticed your phone restarted or soft rebooted itself
Assuming you have never modified your phone it will be impossible to say why your phone is randomly rebooting without an adb logcat recorded at the time of the random restart
If the problem persists you might have to factory reset your device
This may also happen when you have a 64bit twrp installed, even more likely with magisk.

OK, phone was never modified, but I think it might be hard to grab a logcat of it. I don't even have a PC.
Same problem but now it's in a bootloop...
