My Dead Nexus 5, Is There Any Hope? - Nexus 5 Q&A, Help & Troubleshooting

So, I week ago, my Nexus 5 took a dump on me and no longer turns on. When I plug it into a charger, all it does is a continual bootloop and I cannot get it into fastboot, recovery, etc. no matter what I try. All I get is the Google splash screen and it reboots again. Pressing the volume down button as it's booting gets me to the screen where I can attempt to get to fastboot/recovery for about a second before it reboots again. After this happened, I did some research and found that some Nexus 5's have had issues with the power button which seems to be the case here. Has anyone experienced this and if so, were you able to get it fixed?

I saw that recommended on one of the sites I was on while troubleshooting, tried it with no luck. I already ordered a new phone but I had a bunch of pics on it that I would like to have recovered. Ah well, it was worth the ask. I know of a local place that does cell phone repair, perhaps I'll give them a call.

It is very cheap to replace. Btw check goigke photos on web. Maybe they were automaticaly backed up. I found my photos from my smached phone themre

I've used this solution: https://www.reddit.com/r/Nexus5/comments/2rpfuj/nexus_5_broken_power_button_keeps_rebooting/cq6sqs7/ . It helped me to unstuck the button. After I did it, I flashed custom ROM, which can be waked by volume button, and put to sleep just by double tapping home button, so that I don't need to use power button.

[Q] GS4G keeps reseting every 3 seconds

Hello.
I have searched the forums about my issue, and although there are a lot of threads about phones rebooting, there was none about such exact problem as I am experiencing. I apologize if I missed a thread which tackled this problem.
Symptoms:
1. my galaxy S 4G reboots about every 3 seconds: it only gets to the very first "Samsung Galaxy S 4G T-mobile" logo, and reboot
2. it is possible to access boot menu (volume up+down), but only for a split second, and phone reboots again
3. rebooting starts as soon as in put battery in, no need to even press the power button
All that started by itself yesterday. I thought it was a mechanical fault with power switch, I opened the phone, unscrewed covers, cleaned everything, but found no mechanical issue. I switched batteries, tried starting the phone of plugged-in charger, on usb cable, took out sd card, sim card, put a different sim card in... and nothing helped.
Phone runs on Gingerbread 2.3, stock by T-mobile, never had any other roms on it. Device is rooted.
If anyone has an idea how to approach this issue, please let me know. Or reply with a link to somewhere I can read more. I was not able to find much on this...
Thank you!

The phone sometimes does a reboot loop if u take the battery out of the phone without turning the power off. Just keep trying to turn it on, and eventually it would reboot properly. Take the battery out of the phone for a few minutes, put it back and try to turn it on again. Do this a few times to see if it boot back properly.

Thank you for a prompt reply!
I did take out battery for a long time, well over one hour, and took out sim card and sd card as well. Unfortunately reboot loop started immediately when I placed battery back in the phone. That's what made me think it was a mechanical issue with power button.
I will try keeping battery out a few times again today.
One other thing: the phone had been in hot and humid environment for about 30 minutes before this happened. Not the first time for this phone to experience high humidity, though. However, I did not find any moisture inside the unit.

I had this happened to my phone. Just wait it out and keep trying to reboot, it will come around. Take the battery out and put it back on. Keep on repeating this step.
Also, when the phone is on, try to hold the volume - + and power button at the same time to see if u can get into boot mode.
Also u can use hair blow dryer to blow dry area around the power button.

You have a stuck power button. Take apart the phone and clean the power bottom with compressed air. Then rapidly push the button in and out for a while.
Resolution:
I took the phone apart, and checked the power button (which had been my first guess), and was seemingly all right.
The battery was also not the issue, as I tried 3 different batteries.
Having no other choice, I put the battery back in, and let the phone happily reboot at its own leisure. After over 20 reboots, the system came on. Then a few minutes later the device rebooted again, and the loop started all over. After a while it booted up again. This time I did not wait for the device to reboot by itself, and I switched the phone off with power button, and then turned back on, and it booted normally. Repeated this once more - normal boot again. One more power off, and I entered the boot menu and did factory reset. Once the stock reinstalled, everything would work perfectly - no more issues with boot loop.
So it seems to me as a software problem more than anything else.
Side note: for the last several weeks the phone displayed strange behavior, that is the screen would light up for no reason by itself, and quickly go off. Sometimes it happened once every few minutes, sometimes it happened several times a minute. Did it have anything to do with the boot loop? No idea. But it strengthens my hunch about a software issue, as that behavior also went away after factory reset.
Sorry for the lengthy post, but since I have not found a similar case anywhere in the forums, I though someone might find this interesting. I do not deal with phones except as a user, but some of you guys do it maybe professionally, so maybe this will be a curious puzzle for you to solve.

Hardware not software. You had a stuck power button. By forcing the reboot with the power button you unstuck it. If you don't believe it research Occam's razor. Glad you got it fixed(unstuck) though.:victory:
EDIT: Here are some other people who have had the same issue on samsung phones.

Hardware problem?

I bought an used infuse the other day to fix and sell to a friend. The owner said it was bricked, but I've since gotten it into recovery mode, download mode, and a normal power on. It goes into a bootloop most of the time though, the endless bootloop people seem to be getting when the power button gets stuck.
I've completely disassembled the phone and I can't find the problem. The power button (the white one on the inside) moves completely freely. I've tried booting up the phone with the back housing off so the power button is bare but it still bootlooped. The only way I can get it to boot up is to repeatedly hit the back of the phone onto my hand as its booting up. Even then, the phone will only stay on for 30 seconds or so once it boots. I've read of people fixing this by simply throwing the phone on the ground, but is there a better way to fix this? What could be the problem?
Edit: I think I may try this: http://forum.xda-developers.com/showthread.php?t=2235435&highlight=bootloop
It could be a weak connection on the mobo somewhere.
Edit 2: Yep! I re-soldered the connection around the power button on the back of the motherboard and the phone is working. Got it reset and now I'm running it without the second power button thing in the case.

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.

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 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.

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

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.

Is there a write up on that here somewhere? Guess I will have to search around for it.

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.
