[Q] Phone keeps rebooting - Nexus 5 Q&A, Help & Troubleshooting

Hello, today my phone keeps rebooting for no reason. It just reboots immediately after the Google logo shows up or during the flying balls animation. Once in a while it will be able to start, but then back to reboot loop very soon. I can't even use the "Volume down + Power" screen (sorry I forgot what it's called) because the phone will restart immediately.
I didn't install any new app today. My phone is unrooted and is on Lollipop 5.0.1. Bought it used last week after I hardbricked my Moto G.
Please tell me this is fixable. My Moto G is still lying in front of me. The Nexus better not join its brother.

I got the same problem here, all of a sudden it turned off and began this incredibly fast boot loop, I can't enter recovery mode because the fastboot screen goes off as soon as it appears. I'll try to figure something out and come back here. Thanks
I recently installed Lollipop 5.0.1 so it might be something with it too

Thanks. Please tell me as soon as you find the problem. I hope it's just a software (particularly Lollipop) problem and is fixable. It's incredibly frustrating to see 2 phones go down in a 2-week span. **** my life.

ok, so my phone turned on and I actually was able to use it for a while, until I slightly touched the power button (but didn't actually click or even apply force on it) and then the problem occured. So it's either that the power button became overly sensitive or a sensor malfunctioned (I'm a noob so forgive me if I sounded silly).

So, I was looking for answers and figured out it was a hardware problem, the internal power button was stuck. I saw some tutorials on how to disassembly the phone and managed to loose the button up a bit and now it's working fine. Sending it from the phone right now hahah
PS. I'm not a phone master or something, I saw the tutorial and got the motherboard out to fix the button, the worst part was unscrewing those tiny little screws, but it was kinda easy at the end.

That's good news. I don't have the tools to open the phone so I'll have to go to the repair shop next week. Please inform me if the problem somehow returns to you.
P.S: I'm actually gaming on it right now without problem, just gotta be careful not to touch the power button

Dropped my phone, won't boot?

Been a watcher on the forums for awhile, now I actually had to sign up and get some help, LOL.
Anyway, dropped my s2 skyrocket, noticed that it kept trying to reboot every now and then when I used it the same day. The next day, I plugged it in in the evening, and shut off, rebooted, but the screen would go black and the phone would vibrate with 2 seconds in between vibrations. It gets to the "Samsung" word, then the screen goes black in the style of an old tube TV (with the thin white line at the end). Then the vibrations start. So far a useless phone. Took it apart and checked connections carefully (I'm used to working with processor boards quite a bit).
What do you guys suggest? Damaged memory? Should I attempt to reflash? Stuck power button (seemed ok, though)? Bad screen?
Well, probably some kind of physical damage, but hard to say. Anyway, you posted in the forum for SGH-I777 but you have the SGH-I727, so I would suggest that you look in the correct forum.

Oh, thanks for the heads up. Yeah I just figured out that the i727 isn't in "Top Devices" or "Legacy," so you have to go to all forums. Ugg. Already moved. Thanks to whoever notified mod.
Anyway, yeah, any help would be AWESOME. What physical damage would prevent booting past the "Samsung" screen and default to a black screen that intermittently vibrates?
I'll be honest, if ur asking that question probably something u don't have the current skill set to fix. Try to Odin back stock, but if it started post-drop you may be SOL and in need of a new phone.
Got it into download mode after multiple failed attempts. Each time I would get it into download mode, the screen would shut off after about 5 seconds of being on. I tried several combinations of plugging it in first, then installing the battery, or holding down the button while I plugged it in with no battery, etc. I had just given up after getting it into download mode briefly for the 20th time, when I gave it one more go while rocking the on and off button. Technically that is recovery mode, but I let off right before plugging the phone in and it hit download mode and stuck.
So what I am thinking is the power button got jammed internally. I have heard of it happening on other forums. Even though it looks good and clicks upon external examination, the pressure circuit on the inside might be in contact. Anyway, just one theory.
For future though, I did discover that you don't HAVE to have the USB unplugged prior to getting into download mode. On the contrary, a power source must be present in order to register that the keys are pressed PRIOR to initiating USB input. Thus, you can actually remove the battery, plug in the USB (power source), then hold the volume keys while replacing the battery. Goes into download mode that way, too.
Will keep you guys updated. Might need a bit more help if the phone starts acting up again.
At this point, if the Download mode still holds ok, should I consider CyanogenMod, or is it easier to get back a good ROM from stock?
icenight:
Thanks for the reply. I don't understand much about smart phones or how they work, but trust me when I say I have had AMPLE experience with electronics, circuit boards, hardware, etc., particularly in the computer/laptop world. I code quite a bit of websites, and understand almost all things networking and OS. Just never really got into it with the phones.
Getting super excited to see the sheer amount of modding you can do though. Would love to break into a hardware modding world if it ever comes available. That's where it's at with electronics for me.
Well glad u got it sorted, lucky guy you are lol.
As for boards and the like, if it didn't work I would've suggested replacing the motherboard and/or power daughter board. But for a skyrocket may not be worth the money.
Since you're a hardware guy, maybe mess around with the phone and JTAG? Finding a way to unbrick without it would be very helpful
Since the problems started after a physical damage (fall) , I wonder how would Odin or wipe and flash might work !
Definitely a hardware damage...
Yeah, it kinda puzzled me, too. I believe the power button might have been internally stuck, but that's just one idea. Could have been a loose connection, too.
Can you lose some solid state memory with firmware on it, but the SS memory still be OK to right another copy on?
More than likely it was your power button

Nexus 5 Bootloop - can't even pass bootloader screen

Hi All!
Today is a very unfortunate day for me.
I was viewing whatsapp and all of a sudden my phone turned off, turned back on and it has been rebooting ever since.
I have tried all possible troubleshooting steps to see why it is happening but I can't even get into other screens like recovery, bootloader because it restarts right away.
Had a chat with Google and they wanted me to send my old phone and place a hold in my credit card -blablabla.
Obviously when they receive my defective Nexus, they will see the bootloader screen with an UNLOCKED icon.
That will be bad for me - because they could charge me money for a new device (the one they are sending ahead).
I would rather wait for the Nexus 6 instead of repaying for my defective 5.
Is there a way to maybe force it to be locked again before I send it in?
I have one of those JTAG connectors and I was just wondering if it will make any sense if I try that.
Any help would be greatly appreciated.
It sounds like your power button is stuck. Mash it a number of times and see if that frees it up.
Also, if you have a case take it off

Yup, seems to be an hardware problem with the power button.
By the way, if you can't fix it : Seems that Google doesn't care about unlocked bootloader if it's an hardware fault
I actually initially though it was the power button so I removed the case check and mashed it a lot but how it turns of turns ON doesn't make sense because if the power button is stuck usually you have to wait 3-4 seconds before it turns off.
The behavior is like this - Google Splash screen, 1 second pause, vibrate, turn off - Google Slash Screen, 1 second pause - NON stop.
Still it could be possible but I'm hoping they wont charge me anything if they send me a new phone. I would rather wait for the Nexus 6.
They actually asked me if I was rooted and I said NO. There was a chat log on it. Oh well.
I had a similar problem and I think it was the power button as well. I RMA'd it but I kept smacking the crap out of the back of the phone and around the area of the power button. I noticed it'd start getting further through the boot process and eventually I was able to get it to boot all the way through and actually stay. I guess I smacked it hard enough to knock out the button, but I still went with the RMA anyways.
Maybe try smacking it around and see if it stays on longer?

I think you are all right. Now that I got home and observed it more. It is a stuck power button! I'll try to smack around it and have the bootloader locked in again and RMA it.
Do you think once they see it is being rooted, they will void the warranty even though it is obviously a power button issue?

Nexus 5 boot loop

Hi,
My nexus 5 constantly reboots at the google logo. I think it is a power button problem.
I bought my nexus 5 from the google play store but I do not live in the US, so RMAing it would be difficult.
So is there any way I can fix it? I tried tapping on the power button on the mother board but it didn't help.
Thanks!

I think your phone is soft-bricked... Try to boot into custom recovery, factory reset, and reflash a custom rom.

I have the same issue but I cannot get into recovery or anything else. There is not enough time before the phone reboots again. I have read of people having success but it seems rather rare. The strange thing is that I can press or tap (with luck) on the back of the phone, near the power button, and the phone will turn on. I am sure this is a hardware issue but I got mine from T-Mobile and my bootloader is unlocked and on Android 5.0. The bad thing is that I am now able to JUMP! and was looking at the Nexus 6... oh the humanity!
On an side note: When pressing on the back of the phone (see above) repeatedly I was able to get the phone to fully boot but once I quit it rebooted again. I have not been able to repeat this as of yet. I am leaving it on the charger and hoping that it will somehow right itself like other have reported... that is unless anyone has any suggestions.

I agree. I took the phone apart and messed with the components but nothing has changed. When I was able to get the phone to book all the way up "Power off" appeared as if I were pressing the button. I am not sure how to fix this.... I am sure that T-Mobile will not cover the warranty since it is unlocked.

it should be a relatively inexpensive fix at any local repair shop. or you can try repairing it yourself, can probably find a youtube vid about it.

I have not found a video, yet. I tore it down as far as I could but I will keep searching. I am 99% sure that it is hardware related but I don't think that T-Mobile will swap it out or let me use my JUMP! because of the unlocked bootloader. I knew I should have relocked it when I put 5.0 on it!!!!

you still can, its very simple. in fastboot.. fastboot oem lock. or if you have root, the boot unlocker for nexus devices app. you can lock or unlock the bootloader with the app, if you have root. personally, i dont think they would even know about the bootloader being unlock.

The issue is that the phone reboots about every 2 seconds making it impossible to make a connection through ADB, recovery, or anything else. I did, however, find a solution/idea on a post by "nadrojcote":
"For the last week or so my power button/lock button has been intermittent, sometimes having to hit it 5 times or so to get the screen to unlock. Yesterday it all of a sudden stopped working and I couldn't unlock.
I am making this post to share my fix I found for the problem. Seeing how my phone is not under warranty because I have already replaced the screen, I took to tearing it apart and seeing what's going on. Hoping I could order a new power button, unfortunately the button is soldered onto the main board. Upon taking it apart I realized I had put a little shim in between the power button and the plastic button in the housing as a "rattle fix". This is what I am thinking caused the problem, this caused me to be putting too much pressure on the power button and caused it to over time break apart the back of the actual buttons metal housing on the main board. I removed the shim and it still did not work. I was going to take the main board and heat it at a low heat in the oven in hopes to reseat solder points, but before I did that I tried using a fine pair of needle nose pliers to crimp the back housing of the button back together. Luckily this worked. Unfortunately I do not have pictures, but if someone else has the same issue you should be able to see what I'm referring to by comparing the power button to the volume buttons on the mainboard, there is a metal housing around the actual button that is soldered to the main board, it has a slit down the back side of it that allows it to spread apart. The volume keys should be tight.
THE PROBLEM: Power/Lock button stops working
THE CAUSE(assumed): Nexus 5 power/lock button rattle fix
THE FIX: Using needle nose pliers to crimp the metal backing of the power button housing good and tight.
I hope this helps others out in the future as I'm sure I wont be the only one with this problem."
Now, I did not have a loose power button and so did not mod it. I did however take the phone apart and pull the board out. On the back of the board, opposite of the power switch, if an aluminum(?) case which can be removed. Under this there is another aluminum housing with a circle in the middle of it. The circle was somewhat bent touching the board parts below so I carefully bent the circle up. Next I gave the power switch a few "gentle" taps and pressed the casing around the switch to hopefully make it tighter as was recommended by "nadrojcote."
As you can tell from my word use, I am no where near an expert on anything electric BUT my phone is now working. I have not put it back together yet but I am in the process of restoring it to factory and locking the bootloader in case I need to send it in. I have sent some major prayers to God today! (If you do not believe in God you don't have to say anything negative about my post... just carry on)
This happens to me always to restart device
There is a solution to this?
What this fire button solution problem?
Who tried to replace power-on button to know is% 200 percent of the problem?

Nexus 5 restarting regardless of ROM

So I've tried factory wiping and installing a few different roms and no matter which one I go to I keep getting these random reboots. This is particularly troubling when I restore an older rom that I know I was not having this particular issue on.
It is making my phone pretty close to unusable since it will often go into an "Optimizing apps!" speil draining battery and taking an obnoxiously long time to reboot. Not sure what is up. Any suggestions?

Try with a clean flash (or the factory images) without user data/modifications and see if your RRs are still there.
Is the power button stuck by any chance?

The button will NOT seem to be stuck, even if it is, as the contact is made internally. My bro´s Nexus had this problem, and by the end it kept rebooting constantly because the button was making contact on its own. I fixed it by tapping vigorously at the area between the power button and the camera and that made it work.
A way to know if it is stuck could be to press the volume down key as soon as it restarts, if it goes into recovery, then there is no doubt the power button is stuck.
Don´t dismiss hardware problems, as many Nexus are affected by the power button issue and you already tried software solutions which didn´t work.
Hope you sort it out. Remember to use an app to avoid pressing the button so much, such as when waking the device. I recommend Gravity Screen, but there are many other options.

Holding down volume after one reset actually put me into recovery. Plus it's restarting at times in recovery now :/
I doubt it's under warranty since I got it in feb 2014 x.x

If you got it directly from Google, I'd try calling them up and asking for a replacement even if you are a few months off the warranty period, I have read some stories of them honoring warranties in order to get rid of stock. That'd be true even now that the new Nexus is supposedly releasing this year. Nothing wrong with trying, you might get a new, shiny phone.
That being said, don't worry, it's perfectly fixable. The part that gets stuck is not the button itself, but the part that goes into the motherboard, so don't bother fiddling with the black button. I managed to fix my brother's button by doing the following:
- Clean the area between the button and phone of debris or any dirt that could be causing it to be stuck. This is just to be on the safe side, as it is unlikely that it is the cause of the malfunction.
- Take the case off the phone if you haven't, and then put it upside down and tap vigorously with your fingers in the area between the camera and the power button. It might not work the first few times, but it eventually will release the part that is stuck.
- As soon as you can get it to turn on without rebooting itself, install Gravity Screen, or any other app that replaces the power button to wake up or turn the screen off. You are looking to use the button as few times as possible.
After doing that, his Nexus went for being unusable due to constant reboots to working fine. It's been almost 6 months since it happened so it is bound to work, just don't lose heart and patiently work at it. Tap a bit harder if it's not working. Let us know whether you managed to fix it.

I'm going to get in contact with google. I tried pushing down on the area between the camera and it didn't help much. It has started working again properly after a really peculiar work around. I just don't want to have to be super cautious of a button for the rest of the time i own my device :/

Well someone mentioned maybe trying to clean it out somehow. I tried canned air and that didn't do anything so I formed a seal over the button using my mouth and then proceeded to exhale. It has yet to give me any trouble since then.
Had exactly the same issue, reboots over and over again, couldn't boot to bootloader without reboot...
What helped for me was something I read somewhere else, don't remember where, was knocking on the back cover between camera lense and the power switch, did it 4 days ago and it works since than..

Sounds sexual
You can take the back cover off, and if you are careful there is no sticker or seal that would tell google you have opened the device. It is difficult to pull all the way off, the vibration motor is attached to the case back and comes off with it so it would seem stuck. You just have to keep pulling.

Pressing on the area between the camera and the on switch seems to help a lot of people it didn't seems ot have much of an effect for me. While my phone hasn't given me issues since shortly after I posted this thread I'm kinda worried I'm one drop away from the issue coming back

Would this allow me to repair it?
Yeah but you'd need to unscrew a plastic cover that is inside the phone. Phillips head screws, jewelers screwdriver size. Depends on if its dirt or a broken switch though.

Sorry to disappoint everyone but this is a widespread problem that google is aware of fro some time now. It's not the power button but it's burried deep in the software and appreas to have popped up right after the Lollipop 5.1 up date. Check out all the posts on Google
https://productforums.google.com/forum/#!topic/nexus/IJSOuc7gw0w[376-400]
While it apprears to be confined to the Nexus 5 I have had it happen with my nexus 4 just running stock L 5.1
I hope that casts some light on it
Weirdly enough, my power button works flawlessly on 5 and 5.1. Red 32gb from the google play store. I've opened the case multiple times and put Arctic silver knockoff heat compound in sloppily and without regard, no issues other than sprint screwing up their spark LTE rollout.

Sorry to disappoint everyone but this is a widespread problem that google is aware of fro some time now. It's not the power button but it's burried deep in the software and appreas to have popped up right after the Lollipop 5.1 up date. Check out all the posts on Google

While it apprears to be confined to the Nexus 5 I have had it happen with my nexus 4 just running stock L 5.1
I hope that casts some light on it

Sorry, I disagree. While some instances might be related to software, it has been proven that there is in fact a problem with the physical button getting stuck on Nexus 5 phones. You can check it online and will find lots of hits and even YouTube videos, most of them around the time before lollipop.
Best way to check whether it is software or hardware is to press the volume down key when your phone reboots by itself. If it takes you to the recovery, you can bet your cat that it is not lollipop's fault
So I'm suspecting that I have the wonky power button too but.....
I haven't been able to get it to go to recovery when pressing power down and I've defintely had a few restarts very recently.
More importantly, and something that I haven't seen anyone else post about; more often than not my N5 just shuts down. It's usually when I've doing something with the phone (today was flicking through my GPM library). I'll power it back on and it will boot cleanly and then (more often than not) power down again. Other times it will bootloop, but that's rare. It seems to me that if I let it boot up and then don't touch it for a while, it will stay up but I'm not sure that's consistent.
Anyone else seen or heard of the power button causing a powerdown instead of bootloop?

You will need to troubleshoot this the old-fashioned way. Have you installed any updates, apps, mods or anything recently?
Best case scenario would be that you flash a stock image without restoring apps, kernel or any mods. Run the phone for some time, couple of days or so, and be on the lookout for power downs or reboots. After that, you can try adding a few apps at a time and keep checking. If the phone reboots even with a clean factory image, then I'd have to say the hardware is faulty. Could be the power button, could be something else.
Try it out and let us know

Disabled power button but it reboots my phone if I touch it

Hello,
I have a Nexus 5 with Android 4.4.4 and CyanogenMod 11. Like always, it had been working really find untill today, when it started to reboot and entered in a loop. I found out that it was because the power button was broken and with the lightest touch, it would activate.
Searching through the Internet I found out that many people happen to have this problem. I tried to disable the power button editing a file that is found under /system/usr/keylayout/qpnp_pon.kl, where I had to simply comment the line where the power button was.
Now, if I click the power button it doesn't happen anything, like I was expecting, but after 30 seconds of clicking it, it shuts down and it reboots like if it was an internal error or someting similar that caused that reboot.
Is it possible that disabling it the way I did could cause any type of problem that made it reboot after touching it?
I know it's an internal problem or something like this because when I touch it, it doesn't lock the screen or show the power menu, so the button itself is kind of "disabled", but it keeps causing this problem.
Is it good what I did? How can I solve it?
Thanks!

I had the same issue unfortunately. My N5 is still at LG for repair and it's taking much longer than they told me. Which is good of course. Like most smartphones now though, a 10 second power button hold will forcefully reboot the phone. It's hardcoded in the phone and no matter how much you try to disable it through the OS it won't make a difference until the rogue button is physically taken off the motherboard. If you're in Europe though and your phone is still in it's 2 year warranty I would strongly suggest flashing a factory image, relocking and calling LG (or Google, if the device came from Google).
Hope this helps.

Well... It's been like three years since I bought it, so I guess the warranty is over...
And if I want to disable it, I will have to do it manually and disconnecting it of the motherboard, am I wrong? I guess I'll either have to live with this problem or buy a new phone... Today it's not my lucky day! Hahahaha
Anyway, thanks for your reply!!
Many owners have the power button issue. A competent cell repair shop should be able to replace it.

Yes, that's true, I've found a lot of people over the Internet with the same problem.
By the way, I could finally solve my problem; after searching for a while, I found a YouTube video that showed a peculiar way of solving it... And it actually worked!
Well, it looks like I cannot put the link because I'm under 10 posts :cyclops:
Well, here's the video code if anyone is interested: _QpSSCifxAw
The Internet is amazing! Hahahahahahah
Thanks for your replies!
Are you referring to banging the power button? It wouldn't work for my friend's power button. He had to have it replaced because it failed a multimeter test, apparently.

Yep, exactly!
Like the video said, I bumped my phone a little bit because the power button was kinda stuck inside the phone, and that really worked...
I was amazed! And I'm so happy it worked! No need of having it replaced. [emoji16]

How did you do that?

Just hit the phone into your hand so the power button gets unstuck.
You can see the video I mentioned above for a clarifying idea on how to do it.
