Nexus 5 reboots itself to google logo - Nexus 5 Q&A, Help & Troubleshooting

Hey, I really hope someone can help me with my phone. A few weeks ago my phone got stuck and shut by itself and since then it has been working alternately until the beginning of this week when it wouldn't turn on. What happens is that the device gets stuck (freezes for 1-2 seconds and then reboots itself) and when it tries to boot back it hangs on the google logo or get stuck on the boot animation. If I wait some time (10-20 minutes) the phone will boot and work untill it gets stuck again and refuse to turn on and so forth. I flashed the system image and also did a factory reset. Thats why I think it's probably a hardware problem.
Did anyone come across this or know how to fix this?
Thanks in advance for anyone who can help!

Possible power button issue?

Thanks for your reply,
It's very unlikely because of the way it freeze, the way it wouldn't turn on, I also took it apart and saw no reason to belive the power button was faulty (feels quite clickable).

Even if the button is clickable does not mean it is not a power button issue. If you have a multimeter, you could check it.
Could also be a battery issue?
The bootloader remains unlocked after rebooting into fastboot? Tried various stock Roms? Flashed userdata.img file when flashing a stock rom?

The battery is quite new, I actually replaced it myself, but even connecting back the old one didn't show any change so no signs of life there. I'm not sure how can I check the button, isn't it plastic? And yeah I flashed the images as they appear in google site.

You can use a multimeter to test the contact points. The power button works by momentarily complete the circuit or creating a temporary short. There should be three solder points near the power button.
It reboots on kk too?

I will try to test the multimeter and report back. I flashed kitkat and it rebooted as well. Thanks for the help!

It's very likely the power button issue. My Nexus 5 was exactly like this (Boot into Google logo/bootloader repeatedly ). I replaced the power button on the motherboard and it works perfectly fine now.

Infuse Veterans come in here, Charge Loop [VIDEO]

Phone was working good, i flashed a new rom, and everything went down hill. I odin'd back to gingerbread, and i was still get the never ending charge loop. I was able to get into download mode after 45 minutes of button pressing, i still had the same problem. Well i then decided it could be a hardware issue. I searched around on XDA, and i already seen the bootloop thread. I decided to desolder the power button, as the symptoms my phone was having were 90% similar. It was a no, i even soldered the button off. Well, i decided to order a new power button on ebay, i have to wait three days from now to install the new button, but as of now.......... could it be something else?
just same problem as you bro, it is a hardware issue as in the power button is stuck to "1"..
you really need to replace it, i just got my phone fixed from that..

Phone won't boot

Hey guys,
My phone shut off unexpectedly today and now won't turn back on. When I try to power it on I see the Google logo for a couple seconds and then it'll just shut off again. I tried holding the volume up/down buttons to access the bootloader, but right after I get to the screen it just restarts itself again.
Connecting to power (AC or USB) causes it to constantly reboot over and over, it just shows the Google logo for a couple seconds and then restarts again.
Any ideas on what I can do?

Provide more information for a starter - stock? unlocked bootloader? rooted? third party recovery? rom and if yes which?
If it's stock I'd RMA it.
If not what did you do immediately before the problem started?
try holding the power button for > 2 seconds which should turn it off completely, leave it on a wall charger for at least a couple of hours then turn it back on - I doubt it'll fix the problem but it's a simple thing to try...

Everything on it is stock, no ROM, not rooted. I had just taken it out of my pocket to check the time, put it back in my pocket and then felt it vibrate, took it back out to see it at the Google logo and haven't been able to get it started since. There was one or two times when it got past the Google logo and started to show the start up animation (the four colours bouncing around or whatever it is) but then it shut off again.
I tried holding the power button to completely turn it off, but plugging it into the wall charger just causes it to repeatedly attempt to boot like I mentioned earlier. I'll leave it for a while and hope for the best
Sounds like the mobo is bad. Most likely will have to rma it.

Maybe not. Sounds like a stuck power button to me.
OP does the phone just endlessly repeat this cycle? If so it's rebooting itself do to a stuck power button. One other users already reported similar issues and his power button was indeed stuck. Mash the power button hard for a minute to see if you can unstick it.

You got it!
Thanks so much, really wasn't looking forward to waiting for weeks while the RMA went through. The button didn't appear to be stuck - it was still clicky - but after mashing it for a minute it started up normally and appears to be fine now.
Did you flash any ROMs or anything previously?

brother the issue is gone, as mentioned "sticky power button" was causing it. read the thread before posting. btw thanks for effort anyway... haha
:laugh::silly:
Hi all. Sorry to reopen an old thread (but xda suggested I check here before making my own thread).
I think we have the exact same problem with a Nexus 5. Unfortunately, bashing the power button doesn't seem to be helping (and makes me feel slightly silly .
Anyone know how much effort it would be to take it apart to get to the part that's stuck? Any good instructions?
Thanks.
Weird, I have the same issue starting a few hours ago. I updated to the Oct 17 beta of Cataclysm then a hour later it happened. But was told it sounds like the power button issue.
Took it apart, tried to fix it. If plugged in I can get into the bootloader, but then it reboots again. I've tried tapping it on a hard surface, and it gets seems like it almost fixes it because it'll connect to my laptop but then reboots again.
Could it be the battery? It was fully charged but then died as I was deleting hundreds of photo's in Dropbox to move photo's over from my phone because it was full.
I too am running into this same issue. My screen cracked so I replaced the digitizer with some success. In the process I damaged the battery and needed to replace it. When I got the new battery and replaced it my phone is now unusable.
When unplugged: I turn on the phone and it's running the ANDROID animation then turns off.
When plugged in: I turn on the phone, the ANDROID animation runs then the phone restarts and continues the process over and over again.
I then flashed the phone with Marshmallow and the same thing happens. Except now that I flashed it I get the Android icon with the spinning gear. So; I flashed it back to 5.1.1, but the same result.
Could I have physically damaged something inside or is it a battery issue? Thanks for any insight.

[Q]Nexus 5 boot loop at Google logo!

Hi,
I've been using Nexus 5 since Nov '13, but this is the first time i'm facing a serious issue in my device.
I was browsing through Chrome and my Battery was 73%, all of a sudden my device rebooted and here comes the main issue/problem.
My device is suffering a boot loop only displaying the google logo for 3-5 seconds and again it reboots.
Occasionally the boot animation starts but no success, again it reboots.
I tried to enter fastboot menu, it enters but it doesn't stay there for not more than 2 seconds. So I can't make any choice over there.
I tried all the combinations (VOL UP+ Power, VOL DOWN+Power, pressing all the buttons), but its of no use.
My device is out of power now.
Even when I plug my device to charger/computer its not showing the battery charging animation instead the reboot loop occurs.
I suspect it can be a problem with the power button in the board.
What do you guys think?
Is there any Solution for this weird problem?
hoping for possible and positive replies.
My device details:
I'm running Stock Android 4.4.4 with stock kernel.(not modified any system files)
TWRP recovery V 2.7.1.1
UNLOCKED ( @present Locked)
ROOTED. @present Unrooted)
Try pressing the power button hard and see if it helps. Probably a power button failure.

Thanks for your suggestion, but I tried holding the power button for more than couple of minutes, No use of it.
While charging I can't even completely turn off the device, the bootloop occurs continuosly.
I've kept in charge for about 30 minutes but no change in its behaviour.
I haven't recorded the video, I searched youtube and found the exact problem.

As I said earlier, it's most probably a power button failure. RMA the device or get it repaired at a LG service center.

Yes you can. Google don't care about root and unlock, just like LG in case of nexus 5 because it is a google phone.

If you've bought your phone from google play store, then RMA it. Google accepts rooted/unlocked devices as well. However, LG is a different story altogether. Here in India, they don't provide warranty if the bootloader is unlocked. Whether it's a nexus device or not. You will need to check it up.
Thanks a lot.

I have decided to reach the nearest LG care and look up for a solution.
My deviced turned on.... but after 5 minutes its off again
by making some irregular presses in the power button. the device turned on.

I have the same issue happening here. All the place I go searcing for an answer andthey say that it is related to software. I suspect too that might be something to do with the power button. I've tried to open it, took of the motherboard, but it seems to be okay.

It might be an issue with the power button.
In my case it was the power button, which tends to rattle and its not fit enough.
As I lost the copy of bill, i can't send the device to LG care.
So today morning I tried pressing the power button and as soon as the google logo appears I started to tap fast at the back cover with my finger right behind the power button.
SURPRISE! the device booted succesfully and was using for about couple of minutes.
Again it started to boot loop.
did the same procedure to boot. now my device is running for more than three hours and I don't know when it would again go to bootloop.
Its just the problem with my power button and I will soon get the bill copy from my retailer so that i will send the device for repair/replacement.
Meanwhile I've locked my device and set the tamper flag to false.
EDIT:- Now my device is back to normal. Thanks for your valuable responses. Its just the power button failure.
Useless service centers!
Today I went with my device to LG service center, but they were not ready to accept my words regarding this issue.
Surprisingly I found almost more than 6 peoples who bought their Nexus 5 for the same reason.
The technical person in the service center said that it might be due to software update and he suggested a silly solution, After each OTA update he asked me to uninstall each and every app and reinstall again.
I was repeatedly arguing him that it was a Hardware problem and its related to power button, he is not ready to take my words.
I also explained that when the problem existed in my mobile, in OFF condition if device is shaked too much it turns ON without even pressing the power button.
As many of them were waiting there with the same problem I just showed live demo of the problem.
Finally they said if again the problem occurs we should remove the cover and disconnect the battery and then again reconnect it.
Really frustrated spending a whole day in the service center. Main reason is the person in the service centers and technically backward and they were not able to understand the problem.
Is there any other solution available other than service center (Is there any possibilites of contacting google tech support directly) so that my power button gets repaired before the warranty ends!!!!!!

THANK YOU!!! This is the most helpful tip I've found so far! I started tapping its back part while charging the battery, and then I was able to turn it on, but when I quit tapping it the phone shuts down. It is really something related to the power button because the phone was locking itself constantly while it was working. I made some progress and I will keep trying until I make it work permanently. If you have any more helpful tip, please, share it with us! I've been trying to fix it for 3 weeks and Im getting crazy with this! Also, I moved to Brazil and there's no warranty here, so that's why Im trying to fix it by myself.
Did you contact Google and get it finally fixed?
Thank you and good luck!
i faced the exact same problem..
initially i thought it's a software problem..but in reality it was a hardware fault.. power button was stuck may be..
after repeatedly pressing the power button phone finally booted up..
thanks for the tip
I have the same problem I don't know if I can give the phone to LG care cause I'm in Mexico and I shop my nexus in usa. I have noticed that if I unplug the phone to the charger while Google logo is on the device turns off
Started happening to me a few hours ago....
tapping close to the power button seems to work but it shuts down once u stop.
attempted to repair it myself but im not seeing anything physically wrong with the tiny power button (inside).
leaving the phone off for a few hours. hope that works.....anyone else found a solution besides returning it to Google?
edit: I solved the problem!!!! (voided my warranty as well. lol)
the physical power button (internal) was stuck.
1. I opened the nexus 5 (using any repair guide)
2. I located the internal power button (very tiny)
3. I gave it a few taps with the base of my screwdriver (not too hard but not too soft either)
after re-assembling (partially) the phone came on for about 10 minutes but the problem started happening again so i disassembled it once more.
THE FOLLOWING MAY NOT BE AN ACTUAL FIX (I PROBABLY JUST GOT LUCKY)
4. (looking from above) the power button is square (half is white and the other half is yellow).......i used a razor blade and gently separated the two halves....not completely separated, just a tiny bit. completely separating the white from the yellow would destroy it.
5. gave it a few taps again and now the phone is working fine.
I hope this helps someone who is unable to return their phone to Google.
I tried to explain what I did as clearly as possible. I will be happy to answer any questions asked.
Same problem
Hey Guys. Same problem here. I was sending a whatsapp message and boom. OFF. I tried to connect it to power but it turns on for a few second, shows google logo and the unlocked bootloader and turns off and again and again..it was at 52% battery charge....I'm unlocked, rooted and on cm11. Reading here, i have understand that it's a hardware issue, and i've bought it since 8 months, so can I RMA it? I'm in Italy and i've bought it from play store..

What did you finally do? I have the same problem.
Workaround to keep your data
I had the same problem already twice. It appears that the cache partitions on the phone is corrupted and therefore Android won't boot. As long as you have an unlocked bootloader you can bring your phone back to life without loosing your personal files. If your bootloader is locked, you have to unlock it first( see here http://forum.xda-developers.com/google-nexus-5/general/guide-nexus-5-how-to-unlock-bootloader-t2507905). This is how it worked for me:
Connect your phone to the PC and bring it into fastboot mode
Download the Factory Android image from https://developers.google.com/android/nexus/images
extract the images from the zip
run "fastboot flash cache cache.img"
restart phone
Done
I hope this can be of help.

Sometimes won't boot up

Sorry if this has been covered, didn't see it when I did a search and found similar issues doing a google search but not the exact same one I'm having.
Sometimes when I try to restart my G3, it won't boot back up. I'd say 1 out of every 5 boots or reboots. I'll hold down the power button to restart the phone, click on restart, it will prompt me and I will click ok, then it will say it's restarting, then goes black and doesn't come back on. I have to pull the battery and usually the only way I can get it to come back is I have to hold down the power button and THEN insert the battery and then it will start booting up. Not a HUGE issue because I can take my case off in only a few seconds, but man if I had one of those huge extended battery cases that take like 10 minutes to put on and off, I'd be hatin' it
SPECS: D850, Lollipop, rooted.
Now I did not have this issue unrooted. This only happened after I rooted the phone. I used it for about 2 weeks unrooted. I'm sorry I don't recall the exact method I used to root it. So I can live with it but I'd just thought I'd ask and see if anyone has a solution or understanding why this is happening. Thanks for reading my post.
Yeah.. this is a weird issue.
Did you ever end up finding further information on this issue? I just rooted and installed TWRP yesterday and I am experiencing an identical problem. When it happens the screen is dark and power button unresponsive, in addition the LED does not light when plugged in. I can recover using one of three methods:
1: Unseat/reseat the battery once or twice (most times twice)
2: Plug into USB charger with no battery, wait for "?" screen and insert battery...then it powers up
3: Insert battery while holding down power button as you mentioned.
I rooted using this method (only method that would work) , and bump'd / installed TWRP using ImagprepGUI
i have this problem as well. Would like a permanent solution.

Unfortunately the only permanent fix at this time is to reinstall stock recovery.
Got the exact same problem on my G3. Rooted and twrp installed. Any solution yet?
I have a similar issue. Mine reboots every time, but when I power down the phone overnight and try to turn it on the next morning, I have to take out the battery to get it to respond to the power button. I have held it for a full minute waiting for it to come on with no response. This has happened twice now. Not a big issue since it only happens when powering down the phone overnight. If I power it off then turn it back on immediately, the power button works perfectly. I bought the phone already rooted, updated twrp to 2.8.7.0 and installed jedi kernel and rom.

Boot loop after rooting MMB29V. Please help.

I was running the latest stock image (MMB29V) since yesterday on my Nexus 5 and today I used the Nexus root toolkit as always to root the device. Well TWRP flashed once and it said it copied the root files to the device. I had it in my pocket for a few minutes and after that it went into a crazy constant boot loop. It will stop eventually but if I keep the charging cable in it won't stop. I cannot get into recovery because I get the "Start" screen but I cannot advance because it reboots too quickly. I have found a few you tube videos where people push the power button like they are playing the old school game "Track and Field" but this does not work for me nor do I think it's a power button issue. I think I stupidly might have hit some kind of button combo while I'm my pocket believe it or not. I pulled the cover off and was hoping to pull the battery but Im not a fan of doing that since its not a simple task. Any help appreciated. This phone is dead to me and that is NOT good. I need to get this working.
TIA
Bill

Possible power button problem?

It quickly restarts. I want to say its not a problem with the power button because it has been fine for a few years now w/out issue and only happened after rooting earlier today. Right now the only way I can even get the phone to turn on is the plug the charging cable in and then the restarting commences. Does it sound like a power button issue? Possibly but its hard to believe, I dunno. Waiting on a call back from Google tech support to see if they are any help.
It could be a power button issue. You'll have to remove the motherboard to find out.
Once removed from the housing, quickly press and release the power button several times in a row using more pressure than normal. While the motherboard is out of the phone, clean around the power button with pure alcohol.

Did NOT want to screw up my phone so I sent it to LG. Took a few weeks but it cost me 78.00 total for them to repair the power button issue. Whatever they replaced also fixed the low volume issue I was experiencing as well so it worked out.
