Can't boot, restarts constantly - Nexus 5 Q&A, Help & Troubleshooting

Bought a Nexus 5 about 6 months ago USED. It has been amazing. I got the latest OTA a week ago or so, not sure if that has anything to do with current issues.
About 2 days ago started randomly restarting. Today, it shut down and has been in continuous loop restarting. I see "Google" and maybe even the boot dots loading, then it is off. Three seconds later, starts again and repeats. Never makes it all the way into Android system. I let it sit for a while and when I pick it up, without touching any buttons, it repeats all of this. I suppose it is probably dead in general, but I don't know. Do you guys have any ideas? Again, I bought it used and from a ma/pap store who said they buy 100 in bulk, which made me skeptical, but they also had a 60 day guarantee and it was amazing the first 60 days and even after. It has been error free for 6 months, so I don't know if this is just a random issue or if the previous owner dropped it in a lake and I got lucky, or what. FWIW the damn thing has been in a case and never dropped, so it isn't anything that I have done I don't think. Thanks for any help.
edit: never rooted, never messed with, always been stock

Another user reported some instability since the last OTA update.
Flashing the full factory images did the trick.

a friend of mine gave me his nexus 5 to repair and its doing something similar. He had ir rooted and on latest 5.1.1 (i think). Either way, he said it was randomly locking up and rebooting. When i got it it had the red blinking light when plugged so i got a new battery. That got fixed but then the constant bootloop showed itself. I flashed TWRP (many versions, 2.6.3.1; 2.7.1.1; 2.8.7.1; the one that worked best was 2.7.1.1). So, once in twrp wiped, pushed cm 12 snapshot, flashed it, pushed gapps, falshed, pushe supersu flashed. Started the system. That precise order of things (ie: pushing flashing, then pushing something new and flashing it) was what gave me best results to actually boot up at least once. Once booted up and logging in and everything to cm i had some sort of stability (even rebooting and powering off) but i think that everything went wrong when i plugged the phone to the computer and it was back to bootloops and not even getting to the recovery. Flashed everything again. Didnt work. Had to leave the phone sit for a while (without the back casing) before trying again, in order, before getting any success. Im starting to think of ovrheating but it doesnt even get that hot...
Dunno if you guys have any ideas on this. Or if i can give you mor details to help us out.
Regards!

Looks like I'm having a similar problem to what is described here, as well as http://forum.xda-developers.com/google-nexus-5/help/bootlooped-dont-how-to-enable-debugging-t3215951
I've had one of my Nexus 5 phones running OmniROM 5.1.1 for some time now, very stably. After trying out the Marshmallow preview and going back to that ROM, I started having spontaneous hard reboots and hard crashes. The phone would often boot loop before even getting to the OmniROM boot animation. It was also very recalcitrant about entering and staying in the boot loader, rebooting spontaneously shortly after rendering the boot loader screen. I was occasionally able to "grab" control long enough to get it to boot into TWRP, from which a boot to Android seemed to usually get it out of the loop and into running Android.
I've flashed back the boot loader and baseband from factory-stock 5.1.1 LMY48M (HHZ12h and 2.0.50.2.26) using the flash-base.sh script from a freshly downloaded and extracted hammerhead-lmy48m. Things appeared to be OK last evening and this morning, but things got worse today.
Now the phone is in a state where it is not responsive to the power button when unplugged. I can hold it down for 30 seconds with no response.
If I plug in USB, it spontaneously starts rebooting, not showing more than about two seconds of the Google boot loader screen. If I hold the down-volume button, I can get the boot-loader screen, but no matter how fast I try to be, I can't select anything more than "Restart bootloader" (or "Power off") option before it spontaneously reboots (to boot loader).
As far as I know, the battery had a significant charge before this started happening.
I see the same behavior if the phone is connected to a USB charging source, rather than a USB port.
I've tried pulling the SIM, but that doesn't change the behavior.
adb wait-for-device never returns, so poking it over adb doesn't seem to be an option.
fastboot devices also doesn't see the phone, for the brief time the boot loader is running.
Any suggestions on how to get this into the boot loader so I can at least re-flash it?

This morning my Nexus 5 was turned off all of a sudden after not having used it for 20-30 minutes. I held the power button and nothing. I plugged it into power and the "Google" screen appeared. It then went into a reboot loop on and off, on and off, on and off. I held the Volume Buttons and it went into fastboot, but then boot looped out again and again. Searching on Google yielded that this was indeed a common problem. [...]

In retrospect, I had noticed over the last few days that the phone didn't seem to respond properly to the power button, either "ignoring" it, or when a second press got things started, it would unexpectedly come up with the long-press-volume menu.

Ok @jeffsf keep going on this thread. I had the same damn experience, that ended with RMA. LG said that the problem is related to some tension change in the power button. After the RMA I used the phone totally stock and never had a problem. Two months ago I switched to blu_spark kernel and some weeks after i noticed some problem. When I pressed the button to lock the screen, phone locked itself and then screen turned on, sometimes showing the shutdown option. So i understood that something was happening to the power button. I tried to overvolt with a +5mV on general offset and since then i never had problem. If you can enter recovery or bootloader i suggest you to flash some kernel with volt change support and then overvolt the general offset... and keep finger crossed

I got a notification for this post since you quoted me. I'm not sure if you're having the same problem but I'll tell you what happened to me, just in case. I called T-Mobile and they referred me to the nearest 3rd party phone repair shop. I went there and after an evaluation, the repairman told me the power button on my phone was indeed broken. They replaced it for $55.
The story doesn't end there though. I took my phone home and a few hours later I tried to use bluetooth and it didn't work. I took it back and found out that unfortunately, when the guy replaced the power button, he inadvertently broke the bluetooth. There's no way to fix bluetooth without replacing the motherboard entirely, which would cost $200. I'd rather buy a new phone at that point since my Nexus 5 was getting old. He refunded me, which was nice. At least the power button worked so I could use my phone. Bluetooth isn't as valuable as being able to you know, turn on the phone, so at least it was a net gain.
After that, I purchased a Nexus 6 and rooted it so I could use double-tap-to-wake (along with the automatic screen on when you pick up the Nexus 6). I also use the following app in order to turn off the screen by swiping up from the home button (I don't care about losing the shortcut to Google Now): Screen Off and Lock
I can now literally go weeks without using the power button on my Nexus 6. (I literally only use it when tap to wake sometimes becomes unresponsive which is rare.)
Bottom line: I will never buy another phone without tap to wake functionality! :good:

A local repair shop here indicated that one sometimes does changing the power switch resolve the issue. They have seen situations where the issue appears to be one of the power-management ICs. Just something to be aware of when examining the potential cost of a repair and who you would have do the work.

Dead photon?

Hello, my Photon started acting up really weird. First of all, it was really slow. I thought it's because I had like 150MB left and it was nearly full data-wise. However, I erased most of the data, and left it with 3GB left. Didn't work and it got worse.
I have these stripes around the display (just at sides, not at middle), while phone is turned on. Doesn't matter if in system, or at boot logo. Doesn't matter, because whenever I get to system, I can be in system for like 1 minute, then every application starts crashing (Apex launcher, Google play, whatever you pick) and I basically can't get anywhere. Also if I go to sleep mode, phone is basically dead and it's pure luck when I will turn on phone again. I am trying every few minutes and it's worthless, because any time I get to system anyway, I crash after few seconds.
What to do? I was planing to install custom ROM yesterday, but never got to that, because this all started to act up. So what should I do? Reset system? Any other ideas? Is phone dead?
Sorry for bad english, no bully please.
Thanks in advance
Update - now when I am trying to start up my phone, I have just black screen with white lines in the middle. Then phone shuts down. I will give more info when I will be at home and can get phone on charger
Well definitely try to charge the device up. You might try re-flashing the stock ROM using RSD Lite... Although from your description I fear your issue may be hardware related.
Could turn device on. Apparently that black screen with white lines was just discharged phone. When I put it on charger, I could again boot into system and it was working until I pressed power button to go to sleep mode and phone is again dead. Will try to flash RSD Lite later today and will post what happened

Charge the device as much as you possibly can before doing anything with RSD. Ideally you should have at least 50% battery in the device when flashing anything.
This is really miserable. I can't really get into bootloader. Because phone after that 'crash' or whatever you want to call it is dead and I can't even see if it's turned on or not. Basically I am randomly waiting when it's gonna restart and then I just get into system. Even if I fully discharge it, it will have black screen with white lines first, it flashes quite couple times and then it will finally boot into system. Also I remember it was ***** in past to get into recovery. Can I do anything from system? Because as soon as I don't turn off my screen by power button, phone is working, though it has those lines on side of LCD (I will try to borrow camera from someone and post it here today).
I set automatic turning screen off for 10 minutes and I am really careful about pressing power button. Sucks there is only option for just 10 minutes, so I have to tap on screen at least for once every 10 minutes or I will not have working phone. **** my life, really.

Why can't you turn the phone off and charge it while off, or boot to recovery and charge the phone in recovery?

About charging it while turned off - Can't because when I try to turn it on again, it's roulette when I get finally bootloader logo and not black screen with white stripes.
And boot to recovery. Is it possible to like download some command prompt application and boot to bootloader from there? I know when I had my G1 (and when I actually understood android ) you could boot to recovery or bootloader via console. I have astro installed on phone, so downloading some console application and installing it shouldn't be problem.
Btw as we are speaking, I tried to call someone and I basically get same thing like when I am going to sleep mode, I get black screen and now I am just waiting, when phone will eventually want to restart itself.

Still sounds like some sort of a hardware issue, is the phone new to you?
You can certainly force bootloader mode, in several ways. When it's off you can hold power + camera and it will give you a choice of what to boot. When it's in Android you can do "adb reboot recovery" or "adb reboot bootloader" depending on where you want to end up. There are various apps which can also do this for you, if you are on the stock ROM but rooted.

Phone is not new. I bought it used about one year ago.
I am not entirely new to android, but I didn't have android phone for 2 years and then I got this one. So I am really pretty **** with android atm
I will try reboot to bootloader from some console application.
I am rooted, opened bootloader, stock rom
Finally got into recovery, what now?
Also, when I once booted to system, I downloaded some root checking app, and root apparently isn't here. Well cornholio told me it is rooted back when I gave him my phone to perform sim card mod, but whatever. However, I am in recovery, but device is not detected by RSD Lite.

Well reading back thru this thread, I was suggesting RSD Lite back to stock. I'm not really sure what you want to achieve tho, what your "final" goal is here.
I'm not even sure what kind of recovery you are booted into - stock recovery? CWM?
Either way, if you want to RSD the phone back to stock, you need to boot into fastboot/bootloader mode - not recovery. Just make sure the phone is charged up as much as possible before flashing in RSD.
Oh, sorry - misunderstanding from my side, thought I can switch to fastboot from recovery, oh well.
Also yeah, stock recovery.
To spread more facts - in case somebody would have similiar problems, when I try to just turn phone on, I have zero success what so ever. There's just this blank black page flashing every few seconds. However, when I remove back cover, I somehow force phone to load to bootloader logo, then I finally get chance to force phone to get to recovery. I will try to get to fastboot

Not sure if stock recovery has adb enabled, but if you have adb you can 'adb reboot bootloader'.
Otherwise do the power+cam trick I mentioned earlier.

Did you remove the getvar lines from the xml file...?
Yes
Weird. I only recall seeing that when people were trying to downgrade... but you are flashing 4.1.2.
The phone is in fastboot mode? What happens when you click "show device"? The "Device Properties" section is eerily empty.
I know it sounds shady, when I am coming back here again in few weeks, just been a bit busy lately, sorry about that.
However, somehow I got phone to flash it. The white graphical lines on sides dissapeared, however I got some new bug - I can't use phone in portrait mode, just in landscape - aka I need to swipe keyboard to have phone working. Also, that thing when phone completely stops working now occurs only when I am in that portrait mode, but I can restart phone this time.
When I finished this, it was midnight so I went to bad, so I tried to set up alarm, if it's gonna randomly shutdown like before and unfortunately, yes it did. I was waken up with this classical white line graphical bug black screen and had to reboot the phone. Oh well, managed to boot to system and it takes 5 minutes to fetch sim card (I have sim card mod from cornholio) and as I said, those white lines on side aka mysterious graphical bug is back.
Unfortunately for me, starts looking like real hardware issue now

[Q] Nexus 5 Won't Boot

Hello,
I have/had a Nexus 5 (8gb) running CM 12 nightly. I was playing a game on it one morning, Racing RIvals to be specific, then a popup popped up on my screen saying Android System UI is not responding. I clicked OK then it locked my device and brought me back to the lockscreen. I unlocked the device with my passcode and it brought me back into the game but now phone was unresponsive. I held the power button down for some time hoping it would restart my device, upon doing this my device turned off and would not turn back on. I held the power button down for some time and then I felt vibrations but nothing appeared on the screen. I kept doing this and sometimes the screen would light up but will be blank and have nothing showing on the screen. I tried booting into fastboot but that was no hope. I think I have almost tried everything there is to do and nothing works. If I can get any help with my issue it will be much appreciated.
Thank You.
If you can't get it to boot, and can't get into fastboot, then it's likely you won't be able to fix it. Let it sit on the charger overnight, and if you still can't get into it, then you'll probably have to RMA it, unfortunately.

Is this the end of the line for my N5?

I'm a serial lurker here and hate to ask for help, but want to reach out (and finally start hitting thanks).
My N5 was on MMB29S 6.0.1, SuperSU version 2.65 for root, xposed v79 (gravitybox, APM+, snapprefs), and ran perfectly fine up until a few weeks ago when I started having issues. Apps would sometimes FC, and (not always right after) system would hang and then reset. Sometimes the screen would go black but notification light still would blink.
Upon reset, it would either (a) get stuck at google screen and bootloop or (b) get stuck at some point during the boot animation. If the phone did start, it would usually work for a variable amount of time - minutes, hours, but usually not more than a day. Other times, the phone simply would not start and required a slowly increasing amount of time to boot while holding down the power button, sometimes not even booting at all. The phone would sometimes be unresponsive to holding the power button for up to 12 hours before the phone booted up again. Not saying I help the power button that long, but tried frequently over that period of time.
Over the past few days I've taken to troubleshooting in the ways I could think of and what I've read here on xda (I can link to any of the threads if you are curious) and the rest of the web. I started by disabling xposed, restoring stock boot image and removing root, and have since flashed completely to stock MMB29V and have followed the advice of @audit13 to even flash the userdata.img file and perform a factory wipe before booting the phone for the first time.
Nothing works. Even after being bone stock now there are still random resets, with the power button having to be held down for quite some time to power back on (if at all). The only difference is that it hasn't been getting stuck on the boot animation when it does power on.
I'm a bit sad, and realizing that this is probably the end of the line for my venerable Nexus 5, but any help/suggestions are welcome. Thank you in advance!

Could be a power button issue that's causing the resets? Have you tried removing the motherboard and quickly pressing and releasing the power button several times in a row using more pressure than normal?

I have yet to try that, but will try that in the next couple days. Might not get to it tomorrow as I have an upcoming exam.
I'm not completely sure if that's it though since the system seems to hang/freeze before powering down, but I can give it a shot. Thank you for the idea!

As a last resort I could try that -- how do you think that would solve my issue? Thank you!
Maybe a battery problem? I'm just guessing at the different things that may cause a boot problem or resets.

System UI has stopped notification stuck in loop right after Nvidia logo.

I have read several threads on similar problems but none that are the same as mine.
I bought my shield tablet (16gb wifi) off Amazon so I can't really tell you much about it's exact specs. All I know is that I was told that only early manufacturer runs had rooting and OTG issues, and that newer runs had OTG out of the box.
Mine doesn't have OTG enabled, and it would not root with most of the common self installing root apps. So I believe it is an older version.
I have been installing all Nvidia updates as the update notification comes up on my tablet except for the latest one released a couple days ago. (waiting for WiFi to down load)
I was running marvel future fight at the time my tablet did a forced shutdown for a low battery.
Later I plugged it in to charge for a few minutes. When I first plugged it in I got the normal warning image of an empty battery telling me I could not boot yet.
I waited several minutes and tried to boot, but the boot process took an extensive amount of time.
But the real issue is that now I have read several threads on similar problems but none that are the same as mine.

I waited several minutes and tried to boot, but the boot process took an extensive amount of time.
But the real issue is that now, every time I boot it up, once the Nvidia logo disappears instantly before the lock screen or anything else can come up, the notification that one of two processes have stopped comes up. Those being System UI, and Cellular Data.
This would normally be no problem but the instant I click OK the same warning pops back up. It is just stuck in the same loop, process stops, I hit OK and repeat for as long as my patients lasts and I try rebooting...
(why a 16gb WiFi only model even needs the cellular data process is beyond me or why it would prevent a complete boot... )
Any way I started research and found the power + volume down bootloader option.
It took me several tries to figure out how to even get the timing right for that to work. But once there it was no help.
First option for Factbook gave this result :
Cold booting Linux

First option for Fastboot
It says cold booting Linux the displays the Nvidia logo, but up comes the same warning of one of those stopped processes that will pop up as fast as I can click OK, for as long as I will click ok...
I tried the recovery option and that gave me the error of no command with the dead android with the warning sign popping out of his insides.
Just hit the reboot option and as of right now it did not boot... Will try holding down the power for manual reboot. As it will not power on normally now.
Manual reboot to the options again and going to try the power off option.
I am thinking that I might be able to fix this by flashing from a pic... But I wouldn't know as I have never gotten into that stuff before.
Cellular data stopped is still coming up on boot attempt... Only other option I know to try is open the menu back up and try the recovery again or maybe on the of chance hitting continue might do something different that changes things up and let's it finish booting.
I assume it is not actually completing the boot cycle as I cannot bring up the soft keys nor does the lock screen come up.
(don't get me started on the evils of soft keys. )
Anyway any help anyone can give would be great!

The problem I have is with the galaxy z flip 3, it worked just fine inthe morning but after it ran outta juice and I charged it to a certain percentage, it stopped working properly, and got into an infinite boot loop, I tried forcing it to restart by long pressing volume down+power , but it didn't work, then I tried opening the recovery by long pressing on volume up+power and yet it also didn't work (I think that maybe it's because it was trying to boot at the time), so have you guys any solutions , please do help me cuz this phone really is important and with all honestly, isn't even mine XD, I'll be waiting for an answer
Your failsafe options are contact Samsung or do a factory reset (and then potentially contact Samsung).
If you can't boot it to anything, the only real option you have is to flash firmware, which likely won't help without wiping.
Unfortunately, not booting doesn't have a whole lot of options that don't wipe data without being rooted. Even then, you'd need recovery.
I see, then I may consider giving it to samsung, as long as they won't reset it, cuz the only reason why the phone is so important is because of the data, altough, isn't there any other way to acess recovery? Cuz I had this problem with the s10 before and I fixed it somehow (a certain Bixby key combination), but this time it seems there isn't any hidden combination.
Samsung is going to reset it. It's a required first step for them to do any work on it, even if the work has nothing to do with the software. What may help find a way to recover the data is starting with how it got to this point. Did you install anything new, change any important settings, or anything else that could have been a part of the issue? If not and it is an unexplained hardware failure, the data is likely gone already.
If it's something you might have installed or changed, it's possible that putting the phone in safe mode and undoing it may solve the issue and let you boot normally.
Booting into Safe Mode:
Make sure the device is powered off (charging is ok, as long as it is not currently trying to boot)
Hold the side key to power on and continue holding until "SAMSUNG" appears and the device vibrates
Immediately release the side key and begin holding volume down until boot completes
If the device has booted into safe mode, you will see a translucent "Safe Mode" in the bottom left

Well I just asked the original owner (my mother), and apparently she doesn't remember downloading anything new into it, and it just went crazy by itself, also something else I wanna note, I tried charging it and it booted into recovery all by itself, I taught it was weird but Still went and wiped the cache and then when I tried restarting it it suddenly ran out of juice once again, also, it's second display shows some weird curruption/bug or glitch-like lines. So based off of this, can you really find the origin of this problem and if there is really any hope of saving it's data XD. Thank you btw, and once again, I'll be waiting for an answer
There are hundreds of reasons it could do that, including a faulty board. Thanks to the removal of physical sdcard support, you'd need to get it to boot into something with at least adb support to pull anything off it. Stock recovery doesn't provide any ways to perform a decent backup, but it sounds like the only option that wouldn't wipe the device didn't work.
I see, alright, thanks a lot, I'll consider resetting it
It may be worth trying to flash firmware first. Go into it knowing it may reset the device or leave you needing to reset it, but it doesn't hurt to try if you run out of safer options.
Same here, same symptoms, happened in front of my wife's and eyes face. We are fairly techy and understand our way around our devices. We also noticed the device crashed then would make it all the way to the home screen launcher and before catching signal the crash would cause a restart at that point I went in and did a cash swipe rebooted right back into recovery by itself then I unplugged the cable and it was acting as if it has a dead battery but when the cable was last plugged in during a couple of crash and then restarts all the way to the home screen I know the battery was at 70 something percent. My next step is going to probably be flashed the current firmware that just released on top of it as a dirty flash and see if I can get it to boot. If not then I'm going to do a hard reset and see if that works. When plugged in it automatically starts exhibiting symptoms as if the buttons are stuck. The devices in the OtterBox and it's fairly brand new I would say mint. Not dirty or any smudges either. all I'm saying is I'm one of those type of technicians that say yeah right when people say it just happened I don't know where but this actually happened I don't know when I was able to witness it. I'll come back and let you guys know what works and what doesn't. (By the way excuse my grammar I was voice typing while driving )

Hello everyone just a quick update. Once I got home I plugged the device into a Samsung fast charger and Samsung OEM USB type-c cable and realize the device booted all the way to the home screen but register the same battery level as I mentioned above. Device was working as if nothing happened to it. So I updated all the apps on the Galaxy store then updated all the apps left over from the Google Play store, I then proceeded to check for a firmware update because I know the April update just released and installed the update with no issues. Updated the apps that needed to be updated again somehow there's always something and unplug the device from the power cable. Everything was working if no issues about half hour later the device cuts off and does not want to power on. FYI I already had my wife contact T-Mobile and get a warranty replacement we only paid $5.00 so my thoughts and conclusion on what's going on something happened to the battery or it's defective. Btw we only use Samsung OEM cables and equipment at home and in the car while connected through Android auto. it's only working while being plugged in it's not charging all the way even though it's registering it's charge level while the device is on.
