Phone shutting down - Nexus 6P Q&A, Help & Troubleshooting

Hi all,
Here's my problem : I recently changed the battery of my nexus, everything worked well, then 48h later my phone starts to shut down without any reason, when I tried to turn it on nothing happened.
Untill plugged it in, then I could get him on, unplugged the phone (the battery was at 60%) launched an app, shut down again, without getting on until I plugged it.
So I flashed factory images (latest from decembre), Everything worked fine for 48h again, until earlier today, the exact same problem happened.
Can u plz help figure it out ? thx

@oussamalabbize It's your new battery same thing happened to me send it back. My seller immediately sent me a replacement hopefully yours will do the same. I bought one of the cheap ones from eBay so I half expected that. Just wish I tested it out for a long while before I put the back on! The replacement one has been working solid now for few months just no temp sensor but can live with that.

Something bricked my phone.

My phone, which I've had since waiting in line on March 24th quit on me today. I'm not sure if it was the culprit but, I installed a program called Lookout mobile security last night 5/6. When I started the phone this morning put it on the table, got some java and when I got back nothing..no buttons working...ok..no problem tried a soft reset...nothing..ok now starting to get worried. pluged into power source..boot up screen. whew..low battery. then blank, a few seconds..boot up screen AGAIN!..by now I'm in full freakout...Attempted to calm down.. didn't work..thought ok..most everything is backed up..lets do a hard reset..didn't WANT to but anyway! Did the hard reset .. Still had the same problem...Had to pinch myself HARD to make sure this wasn't a nightmare. Went to the TMobile store and the associate put me in touch with technical support (they were Super) Going to give me a new phone but, have to wait until next Friday to get it...and then tweaking and rebuilding it to what I want...I should have been ready for this coming from an iphone...All it takes is one $%@# program again, not saying it was the one mentioned above but, one with a malicious code or something that destroyed over five weeks of building a phone from scratch. Sorry about the rant... I still LOVE this phone. .
so you couldn't even boot it in to the bootloader? wow! Maybe you should flash HardSPL before trying to install that program again as there is far less chance of bricking it if you have HardSPL installed. Even if the rom gets completely stuffed, you can still boot it and reflash from SD.
All I can recommend is install a ROM via Micro SD card and maybe doing a Task 29 before you reinstall a ROM

They want my old phone back once I get the new one so, I'm going
to let them have it just as I turned it on yesterday. Let them
find out what the problem was created by.
I was about to install that "lookout" software...but after reading this I might as well hold on.
did you leave it on the charger overnight or did you just turn on your phone in the morning.
if you didnt have it charge all night, maybe all you needed to do was leave it on the charger a little longer before starting it back on.
i noticed that some phones with a dead battery and on the charger will sometimes not stay on until it has gotten a minimum charge on the battery.

Setting up the new phone shouldn't be a big deal if you did actually backup; just stick the old microSD in the new phone and run whatever backup app you had on the card.
I put it on the power supply and it is in the constant loop of
the first screen that appears. I am going to seriously look into
HardSPL. Thanks to all the good input from everybody.
Well now even customer service is at a loss. They cannot phantom why why two separate phones have the same problem. While I had CS on the phone we went thru various senario's to try to get the phone to operate properly. I even had them give me a new SIM card and that did not work...I suggested the problem might be the battery as it could have gone bad. You guys think the phone is playing hard to get--try to find a replacement battery! No stores within a 20 mile radius had one in stock....! Needless to say they are going to ship me yet another phone. plus a new battery and hopefully it will take care of the problem. The sales associate did a hard reset on both my old and the new phone without results so that unfortnately is not a viable solution. Now I am in the game I hate the most........The waiting one! ..

^^ what the op says above. This happened to me (and my gf as well) on our HD2s. The first time (mines) this happened, i hooked it up onto my car charger and immediately tried to turn it on.. it would go onto the TMO screen, but quickly shut down and loop. After realizing I may be trying to jump the step, I unhooked it from the charger, took the battery off, put it back on, hooked it back onto the charger and let it sit for about 10-20 minutes charging. Turned it back on and viola! It wasn't a brick.. I can almost guarantee this is your problem.
But I may be wrong lol...
So, now after 2 replacement phone sent to me, I find out that
it was the battery all along. Problem is that after the second phone
arrived and I had the same problem I called customer service and
explained it to them....They said a battery would be sent next day
air...Ok...called the next day and was told that the rep never sent
in the order...Long story short....I've almost been without my phone
for two weeks now and, all I need is a frelling battery.
Problem is there are NONE around me..I've tried every tm store in
the area, All radio shacks batteries plus...you name it....
I am being sent a battery UPS ground...could take 7 more days.
Just took the battery from my fiance's phone and it works
so, right now I would pay a ransom for a battery just to have my
phone back!
I had to do a hard reset after downloading that lookout trial.
at this point I don't know what caused it..Has anyone ever heard
of an application causing the battery to go bad?...I worked really
hard to keep the battery I had in good condition.. I hope UPS
delivers soon!
This is odd I have used Lookout Mobile on my phone since I had it. Mind you not had it for long, since April but still its never bricked or did anything that hindered the phone. I maybe another program.

Desire HD reboot problem

I was very happy yesterday when I picked up my brand new Desire HD. When I got home I immediately removed the plastic from the battery, inserted my sim card and plugged it in the charger while reading the manual.
After some tinkering around it suddenly rebooted. I thought it was just due to a setting I changed so didn't think much of it. However, it occurred another time later in the evening. This morning when I woke up, I didn't have any signal due to my DHD not recognizing my sim card any more. When I rebooted the phone, all was well. However when riding my train to work I felt the phone vibrate so I picked it up thinking I had a new text. Wrong: I was staring at the boot screen yet again.
When I got home this afternoon I did a factory reset using the phone's menu and hoped it would solve my problem. Unfortunately, when I opened the browser it rebooted again!
So, is my 2 day old DHD really dead-on-arrival or is there something else I could try? Unfortunately this was the last model left at the store where I got it from and they didn't know when another shipment would come in, so I might be stuck waiting for a while if I really do need to get it exchanged for a new one.
Mine is also doing this, also when I turned it off last night to charge it, it kept turning itself on. Any help much appreciated.

imo take it back if a laptop or anything else was doing this i would say there is a hardware fault bad chip sample or something its not normal you should have to live with it take it back asap
or wait if you want but personally you pay that much you want it to work just take it back
Maybe your SIM card is old and causing these reboots? DHD will automaticaly reboot when you unplug your SIM card without shutting it down first so maybe it's just loosing contact.
I've seen cases (various manufacturers) where SIM card would cause hangs, reboots and such. Replacement card from the operator in most cases fixed the issue.
My Nokia 6630 has that issue, it says the phone has to be reboot constantly due to a old scratched sim card, if i try with a new one it works perfectly :|
http://forum.xda-developers.com/showthread.php?t=676402
These reboot issues are a problem with the Desire, Nexus1, EVO4 and now it would appear the DesireHD. For the other phones the solution is to return to HTC for a mainboard replacement.
I really hope this isnt the case for the DesireHD.
As for it being my sim card: I doubt it as it works fine in my old phone (Nokia N900) and an old Motorola I still have. The sim card is barely 1 year old btw.

Yeah, I read about similar problems with the Desire and Nexus One but hoped the problems would have been solved in the DesireHD as I hadn't seen any messages of this problem occurring on the DHD before.
When I woke up about an hour ago, I again had to reboot my phone as it didn't see my sim card anymore. I'll go back to the store in about an hour to get a new one if they have it, and let you know when I get back...
This is just a wild guess, but may you should try to take out the sim card and place it back again. There could be a loose contact, dirt on the sim or some something else that might be causing a problem the phone does not see the sim correctly.

I thought of that last night so I took out the sim card as well as the battery and placed them back again. This morning, the DHD again failed to recognize my sim card so that problem wasn't solved.
The reboots seem to be rather random though, it's not just when I use my phone very heavily.
the issue with the sim card isnt the mainboatd issue, its can be sim or one of the back covers, wird.
Well, I went to the shop this morning to replace my DHD for a new one. The shop I got it from didn't have any in stock anymore, so I had the choice to wait until next week, or go to another shop and have it exchanged there. So I went there, and they replaced my (I think) faulty unit for a new one
So far, it's working like a dream What I noticed that with my previous DHD the charger would buzz very slightly when charging, this doesn't happen with my new unit and the same charger.
I'll keep you updated whether or not my new unit is indeed problem free.
I bought my Desire HD from the T-Mobile shop yesterday. Nice phone, but mine is rebooting every 5 minutes more or less. It seems to reboot soon after the 3g becomes active, but that may be just a coincidence. It also reboots immediatly upon plugging in the USB cable. Very annoying!. I thought I would try resetting to factory default, but that also did not help. I am going to swap it tomorrow, and hope I have better luck with that one.

Same issue here, got mine from three UK yesterday.
Brand new SIM Card with the phone as well.
It was fine most of last night, rebooted once then after setup, like another post didnt think that much of it.
Then this morning it went in to a boot loop, rebooted about 5times in a row and the only thing to correct was a battery pull.
Lets hope its a software issue and not hardware related!
I haven't been able to test my new unit properly just yet. I ordered a new SIM card through T-MOBILE but it hasn't arrived yet. I'm now using my DHD without a SIM card and it has been working fine for the past 24 hours. So I think my SIM card is indeed the problem, as both units rebooted several times with the SIM card inserted but work fine without one.
When i picked up my sgs. It used to have same problem. Everytime i open a browser it reboots. But after i changed the rom it went perfect
Factory reset wont work. Try fresh install from the recovery menu. I think it will fix ur problem.
Most of the time this issue is software related.

Replaced my DHD at T-Mobile
Hi all,
So i was experiencing the reboot problem on my new phone. In fact mine was rebooting every 5 to 10 minutes since i took it out of the box. I phoned HTC to see if there was something I was doing wrong. They told me it's probably mainboard fault and I should return it.
Today I brought it back to the t-mobile shop and they exchanged it for a new one no questions asked. I demonstrated to the sales guy how it reboots for no reason, just to prove I wasn't crazy, but he didn't even ask for proof. The new one seems to be working flawlessly so far.
Here in Netherlands, you have 8 business days to return your device if something is wrong, and they will exchange it. If you wait too long, you would have to send it for repair under warranty. If you are having issues such as this, I would definitely swap it out a.s.a.p because when you buy an expensive phone like this, its meant to WORK!
I noticed something else perhaps worth mentioning. When the first phone package was opened, the plastic piece protecting the battery was not there, and the Micro SD was in the box, but not in the phone. The plastic cover was on the phone however, so I didn't think anything of these things because i don't know how the phones are packed. When I got the replacement phone, I tried to start it and it wouldnt start. Only then did I realize the replacement phone had a plastic protector around the battery which I first had to remove, and the micro sd was already in the phone. When i put my sim in the replacement phone, the fit was tighter as well. This all seems rather dubious to me. Perhaps someone had a play around with the first one before selling it? Maybe it was refurbished? In any case MAKE SURE you inspect the phone before leaving the shop, and make sure your phone hasn't been played with.
good luck everyone!

Horrible reboot
Hi all,
I have been experiencing different reboots due to different reasons. Main reason is the fact of applying too much pressure on the back cover. That will always result in a reboot (I suspect it has to do with the two contacts under the cover).
Another reason for rebooting, as I have experiencing, is unplugging the charger while using the telephone.
I wouldn't be surprised if there are more reasons that cause the rebooting of the unit.
The worse part in my case is the fact that I lost the receipt, thus I believe I won't be able to take it back to have it fixed. Am I wrong?
I've been experiencing the same issues, but mine also turns itself on. I tried factory reset, didn't solve. So I am getting it exchanged as soon as its back in stock with Vodafone.

I am having exactly the same problem with my DHD. It's randomly rebooting 1 or 2 times a day. And when it's rebooted there is no signal and sometimes it doesn't even recognize my simcard at all. Manually rebooting the device then solves the problem for a while, untill it reboots automaticly again....
I have a dual simcard so today I will swap it, but I don't think that is going to work.
I don't have the DHD yet...
But i saw in a youtube movie that the batterycover had 2 contacts.
The guy in de video told that when you take the batterycover off when the phone is on it will shut down.
Maybe your battterycover is not set the good way.

[Q] DZ suddenly wont turn on !

Hi I rooted my DZ about a week ago and installed CyanogenMod 7.0.3. It has worked perfect and I've been very pleased with it.
Last night I set the alarmclock for the morning, set the phone to charge and went to bed.
I then woke up 3 hrs late and discovered that my phone was turned off ?! I can't turn it on and nothing happens when I set it to charge.
My hopes are that its just the battery that's collapsed but what do you guys say ?
hoping the best for you but here's what happened to me:
Out of the blue my Desire Z stopped working: one moment everything is fine and then all of a sudden when i tried to turn the screen on nothing happened. well i didn't expect anything worse than having to take out the battery and reboot, but when i did just that only the home, menu, back and search button went on but not the screen...end of the story, i had to send it to the customer service wait for about 3 weeks (customer service in germany is rather poor because it is outsourced to another company) and get a mainboard replacement.
Maybe in your case it's just a dead battery, take it to the next electronics store and have them check if another battery fixes your problem...Good Luck!
Silly question but you have done a battery pull?

I'll go to my nearest 3 store next week to see if a battery swap will do it. I'm just afraid that it's the whole rooting thing that has caused it and that the warranty wont cover it :/

Bricked My Note 4 :(

So last week my N910F (rooted) ran down to 20% battery and so i put it on charge, thought nothing of it, A couple hours later the phone was dead, extremely hot to touch and just a blank screen with no charging lights, So i unplugged the charger removed the battery and let it cool for about 10 mins, when i put it back together it refused to turn on, tried both recovery and download modes but still nothing tried different chargers and still no lights, nothing. took it back to my local O2 shop to see if i could send it off for repair.
Got home this evening and O2 had kindly returned my phone to my home address, with a letter saying the following -
Thank you for sending us your phone to be fixed.
One of our engineers, has tested your phone and found that unauthorised rework has been carried out on the phone. Unfortunately, this prevents us from repairing it and we are, therefore returning your phone un-repaired.
well after reading this my heart sank and i was guessing i would have to make a insurance claim and hope my insurance would somehow replace it.
I then noticed on inspection of the phone, there was for some reason a new charging cable included with the phone!!!?. I looked a bit further and noticed they had taken the phone apart and it seems they have replaced the charging port, the battery also looks brand new and there isnt a scratch on it (I had previously marked it) So it seems they have indeed carried out some work, So i plugged it into the charger and guess what, it now works fine!!!!!!!!
So thank you very much O2 repair centre!! Im guessing they had to fix it first before they could test if it was rooted or not!!! their letter was a bit confusing though!! :laugh: :laugh:
Congratulations

Does anybody find it weird that o2 would fix mjw2k11's Note 4 only to send it back to him saying that they couldn't fix it because he had messed around with the firmware? Anyway I'm glad that you managed to get your Note 4 fixed.
i dont find it weird. It wont turn on right. but 'O2' wont repair if anyone modify's their phone. So they want to turn it on to see if it has been modified & unofficial but they cant even do that yet. The logical thing for them is to try to get it to boot up, which they did by changing a battery or fixing inside. (which solved the OP's problem). O2 then see's that Knox counters been tripped & they dont do anything further & send it back to the owner. Happy & lucky he is

Bricked My 6P, But Not Sure Why/how.. Any help is appreciated

I'm pretty lost on this one and after hours of searching, have not the slightly clue how (or if) to fix it...if it can even be fixed.
Past few days I've noticed the phone randomly rebooting, some of the times it says my battery is 0% when it's almost full. Today I went to go wipe it and reflash Pure Nexus. While wiping and flashing it, it ended up in a boot loop. I've tried everything to get the phone back up and running. I've tried attempting to flash different ROMs, the stock images (tried T and Q), doing a hard reset, factory reset. Literally everything under the sun that I know to do or have looked up.
Right now the most my phone will do is turn on, shows the Google screen, the reboots and repeats. Sometimes when the phone is off, I have to hold the power button for a minute or 2 to get it to turn on. Still, can only get in the bootloader, but can't get it to boot further than that.
Any help is appreciated, I'm at a loss on this one....and phoneless. :crying:
Pretty weird, if nothing works you should flash stock images, lock bootloader and RMA.

I also tried to lock the bootloader and re-unlock it, with no luck. Called Google and they weren't any help, least outside of what I've already tried. I'll be calling Huawei tomorrow when they open.
As of now, it seems when I unplug my phone, it just turns off. I plug it back in, it goes into bootloop (without me hitting power button). Sort of wondering now if the battery just took a dump?
The phone started acting funny every since I tried to Android N. I'm going to attempt to try flashing N again, just for kicks.
I found a USB charger at work. While not a fast charging one, it was enough to allow my phone to boot up. Apparently there is something wrong with the battery some how. When it booted up, it showed I still have 48% of battery left so I took it off the charger. About 5min after booting it shut down again. Now that it's on the charger again, it'll boot back up and now shows 1% of battery.
I can't figure out for the life of me what the deal is. Looking like I'll need to lock the bootloader and RMA it back for warranty and get a properly operating phone. I'm curious how quick this will happen to get a working phone? I'm up for an upgrade through Sprint, think at this point it's best to go get a new phone to use in the meantime since I have no old phones to use in the meantime. If Huawei gets me a new phone within 14 days I can take the new one back and rock on with Nexus. Kind of sucks, but just my luck.

That's exactly what you should do. Most probably the battery is dead or malfunctioning. Charge it with that spare charger for a few hours, then restore stock and lock the bootloader. Finally, turn it up for RMA.
I never had a single out-of-the-box issue with any of my 5 Nexus devices. I hope the replacement that you receive will be up to the satisfaction.

Thanks for the confidence. I'll do just as suggested and return it.
I'm up for an upgrade, although I have to do online so I don't have to pay an extra $30/month for a phone I'll sell after getting my 6P back. I hate sprint not letting me do it in the store, such a PITA. If I do online I can just get the discount and sign a 2yr contract which is fine with me. Any idea if they will ship a new phone so I'm not without a phone for week(s)?

Sorry, but I never had any experience with an international carrier like Sprint, so can't say. Someone here would be able to answer this better than me. :highfive:
Thanks for the quick reply. I'll call Huawei here in a few and start the process and find out. Fingers crossed they will ship a new phone, even with a temp hold on the money while I send this broken one back. I'll post what I find out, just in case anyone else is curious and searching for the answer.
