[Q] Solution for random reboot/boot loops? - Nexus S Q&A, Help & Troubleshooting

I've been searching the interwebs and XDA for days regarding the random reboots that the Nexus S is cursed with and I was wondering if there are any confirmed solutions? (Phone randomly reboots, and gets stuck at a bootloop with a very dark screen until battery pull).
I've read reports where an OTA was supposed to have fixed the problem and read other reports that stated that if the reboots persist after the OTA then the phone has a hardware issue and needs to be replaced.
Mine has been doing it at the most random times, which is a major inconvenience for me if I rely on the alarm clock to wake me up in the morning.
I've run factory wiped, flashed stock, Cyanogen, and NSCollab and they all have had the problem. Can anyone provide me with some help?
If I can't figure out how to get rid of them I think I'm going to try my luck with a refund or exchange before the warranty runs out.

I just got an AT&T version for my wife during the "free upgrade" promotion. I have not rooted or installed any roms and this phone is having some issues. Reboots at completely random times, goes into boot loops, and even locks on a black screen with the buttons lit. I have been searching for about 2 hours without any real answers. I have been through Aria, Captivate and now NS. Flashing roms and dealing with android quirks is usually not an issue, but I want to retain my ability to return this phone if it is faulty.
What I have tried:
1. Uninstalled questionable user apps
2. Switched SIM cards (used my SIM)
3. Factory Reset
Model: GT-I9020A
Ver: 2.3.4
Base: I9020AUCKE1
Build: GTJ61
Some help/suggestions from some experienced Nexus S owners would be appreciated. Thinking tomorrow will be a return to Best Buy.

I ended up doing an exchange at BB today and the problem is gone. I would definitely attribute your problem to a hardware issue. The new NS that I have is running smoothly and has not had one freeze or reboot yet. Get yours traded in before it is too late.
I would like to add that it seems there is a lot less support/community advice in the NS section than some of the other sections I visit. Strange...

I get the same thing, and frequently woke up (late) to bootlooping...
This is far from a fix or diagnosis.. but this is how I manage:
1. Buy a cheap alarm clock
2. when the phone is bootlooping, I plug in the usb (to computer), open dos prompt and type adb reboot or adb reboot recovery (then fix permissions). If you have the android sdk installed on your computer, of course.
I have a case.. and it's a pita pulling the battery out.
However, before i go to sleep, I've been turning off auto-sync (gmail, contacts, etc, all of them), and it hasn't bootlooped overnight since.
Something to try.. but good luck My signature has my phone version and setup.

Thanks for replying everyone. I went ahead and arranged to have it replaced. In my area only one Best Buy had Nexus S's in stock and they were sold out online. There was an armed robbery in the area near the Best Buy, but I went anyways!
I've got the last Nexus they had and just nandroid restored. Everything seems fine so far!

Not even a week into having a replacement Nexus S the reboots have started happening again. It's happened twice today. This leads me to think, is this a software issue?

Try a different kernel.
Wipe cache & dalvik.
Fix permissions.

Phone keeps randomly powering off!

Hi, been away from the forum, as i have just got back from holiday
i am having a prblem with my desire.. i went to florida, left my phone at the theme parks, desire s, zte blade, ipod touch in the car for 8 hours in around 30-40 degrees. since then, my desire s has been faulty.
my touch, and zte work fine, but my desire has a major problem now. it works normal in use, but when i lock it and put it into sleep mode, when i try to unlock it , it will start up the whole phone again. basically, it powers off on its on randomly in sleep mode.
The problem is really annoying. it is also very common on the desire hd..
http://www.google.co.uk/search?sour...360GB360&q=htc+desire+hd+randomly+turning+off
Im running leedroid port from dhd. i thought the rom was the problem, but it isnt. i flashed other roms, hydrogen, but the problem still exists. shoud i test the stock unrooted ROM?
i dont think it is a software fault anyweay. the phone was working fine for 2 weeks running leedroid, then suddenly i have the problem now.
i have emailed htc, and awating a reply now. so will i need to get it repaired? or replaced as a faulty unit?
Hmm.....does sound like the heat has done it in....damn!
Although there are plenty of other countries where the temp is close to this all the time, you would have thought....
Try installing close to stock ROM with no apps installed, (Yes perform wipe). I'd suggest installing battery moniotr widget and get iot to log full details (including apps), force log in sleep mode so that you can at least see when it dies and what temp it's at when it does and what apps are running at the time.
Although does sound like warranty return issue (at least this way you get a new motherboard and possibly even a new device)...(you might want to check the recommended running temp levels in the warranty book first - just so that you get your story straight)
Positive note: at least its still functioning so that you can re-install RUU etc and mask S-OFF before returning it?
ps
Mines done this a couple of time over the last few months...although I always figured that I've hit the buttons in my pocket?

Cheers Ben! Love how your always here to help!
I'll try installing battery monitor widget , and go back to stock, s-on
So do you think it was the heat that damaged the phone? My ipod touch and zte blade were left in the car, but they work 100% fine
I've checked the warranty thingy, it says do not expose battery to 60 degrees or higher.
But to be honest, I dot really know how hot it could get in the car... Florida is very hot!
I'm just waiting for a reply from HTC now
The phone works fine everywhere else, its just this problem.. I tried cooling the phone by switching it off and taking the battery out, and leaving it for an hour.
The thing with this problem, is that it is entirely random! It sometimes last ages in standby before the problems occur, or within 10 minutes.
How can I prove it to HTC??
I wouldn't worry too much about your phone doing the same once in a few months or so
Mine is happening at least 6 times a day!!
I'll try to keep the thread updated to how it all goes

Hello,
Could have been the heat, but could simply be a faulty motherboard....either way a new device might be a good thing, 1/2 way through your warranty period.
Don't know how hot it gets in cars in Florida....but I know that it can kill pets let alone phones!
Cheers, not worried about my phone, just trying to relate that's all
You're just going to be have to forcefull in your email and exaggerate...even
best of luck

My phone is just a month old now
Hopefully they just send me a new phone
I tried to act pleading in the email, but I did not mention anythig about leavig it in heat or the car. I just said it keeps crashing on me...
Hopefully I get a reply soon tommorow!

Though my phone was not left anywhere where temp was extreme, mine is also doing this since this week,, Also a few months old and I blame the apps installed . I ahd battery monitor and suspected just that prog..
I have not yet gone to a clean rom yet but selectively remove apps till I find improvement....
Meaning there are others with the same problem !

Yeh, some of them have the same problem after a couple if weeks old (not exposed to heat or anything) what causes this problem?
How often do u have this problem??
My old Nokia 5230 has the same problem
Mine has the same problem and has never been exposed to extreme heat. I think the power button is faulty and after some use it get stuck some times and closes the phone down. I started pressing the button with less force and the random power downs stopped happening.
What happened? I have not found a relationship yet. It seems random too me so far. If it happens once more i will go to factory default plain htc stock rom (i have not fiddled with the device or rom)
If it then happens as well i know enough. I will see and report me experience in due time.
Btw its android 2.3.3 build 1.47.401.4

To be honest, I think its more of a hardware problem!
My phone was running fine on stock and custom roms for 3 weeks, then it just started last week when I left my phone in the car
A lot if desire hd users had the same issue as us!
I'm awaiting a reply from HTC now
Will update on what they say.
the heat probably was the culprit
my phone reaches around 45c at times due to the high outside temperature here,but i don't have any problems so i guess yours was heated more
but if you can, try changing the battery it may help
Random shutdown
I also suffered from this. A new Radio + ROM + cleaning some apps has solved the problem.
Thanks for the replies everyone!
I received the following e-mail of HTC today:
Dear Oliver Loh,
Thank you for contacting HTC regarding your HTC Device.
I understand that you are currently experiencing difficulties with rebooting and random restarts.
I believe that the reason for this is because of a hardware issue.
In order to rectify this I would like you to perform the following actions:
) Make sure your device is fully up to date:
Menu - settings - about phone - system software update - tick box - check now.
) If possible test the device with or without a (new) battery, SIM, SD card.
To assist you further I have attached links to the HTC Support Site which will enable you to work through the above step by step:
http://www.htc.com/uk/support.aspx
Once the above has been completed you may be required to do a factory reset, for your convenience I have detailed the steps below:
) Restarting or factory resetting your phone:
Restarting your phone (soft reset):
If your phone is running slower than normal, an application is not performing properly, or your phone becomes unresponsive, try restarting your phone and see if that helps solve the problem.
Please remove the battery, wait for a few seconds, reinsert the battery, and then turn the phone on.
Performing a factory reset (hard reset):
Note: Factory reset will not remove the data and files that are in your phone’s microSD card.
Factory reset is not a step to be taken lightly. It will permanently delete all your data and customized settings, and will also remove any applications you've downloaded and installed. Be sure to back up any data and files you want to keep before you do a factory reset.
Performing a factory reset via settings
Performing a factory reset using phone buttons:
If you cannot turn on your phone or access the phone settings, you can still perform a factory reset by using the buttons on the phone.
1. With the phone turned off, press and hold the VOLUME DOWN button, and then briefly press the POWER button.
2. Wait for the screen with the three Android images to appear, and then release the VOLUME DOWN button..
3. Press VOLUME DOWN to select CLEAR STORAGE or (Factory Reset), and then press POWER.
4. Press VOLUME UP to start the factory reset.
Should the above solution not resolve your query please can you confirm the following and reply to me:
1) Has the device been recently updated/upgraded or changed:?
2) Has a new application been recently downloaded:?
3) Please can you turn off all applications and UN-install any which are unessential, As they may be causing issues:?
4) What have you already done/tried to troubleshoot your issue/s:?
5) When did your issue/s occur or re occur:?
6) Is you device or applications fully up to date:?
Should the above fail to restore your device to full working order, the device (MAY) need to be sent for repair.
I hope that this information meets with your requirements, should you have any further questions please do not hesitate to contact us again.
If this response has resolved your query, and you have no further questions please close this ticket by following the link below. Upon closure of the ticket you will be invited to complete our Customer Satisfaction Survey which should take no more than 1 minute to complete.
To send a reply to this message or let me know I have successfully answered your question log in to our ContactUs site using your email address and your ticket number xxxxxxxxxxxxxxxxxxx.
Sincerely,
Robert

And today i can confirm the problem has occured 8 times today. Now it can do the problem up to 3 times in a row, when the device is in use.
It happened this morning 3 times, 2 in the afternoon, and as i am typing now, i just booted into recovery and the phone crashed on me twice at the recovery screen.
I will reply to HTC and tell them i have the stock rom etc, and will s-on my device and send it for repair soon hopefully
So what's your uptime since you changed??

If the problem persists through multiple ROMs, it definitely sounds like a hardware problem. I'd return it to stock and have it sent in for repair under warranty.
Haven't read all replies... but this is a well-known battery fault (and isn't necessarily triggered by either heat or humidity... it is most commonly a manufacturing defect).
My very first HTC Desire S handset had almost exactly the same issue, only the battery from that handset would power off the phone only when the GSM picked up a signal (I.E.... you get reception, but the phone kills itself instantly. No reception, phone ran fine).
O2 replaced the entire thing under warranty (but I sneakily kept the battery to prove my theory). I placed that battery into my replacement handset, and behold.... EXACTLY the same thing!
Put the new battery in, everything works perfectly.
Bottom line: don't replace the phone, just replace the battery!

Hmm.. it does make a bit more sense that the heat could have affected the battery rather than the phone itself.
The battery is probably unable to run under low power that is used when put in sleep mode so it just cuts itself out altogether.
My hypothesis...
i have the exact problem!!
i thought i was the only one... mine turns off at least 3-4 times a day for no apparent reason.
at first, i thought it was the heat during the summer.. but now that the temperature is getting milder i dont really think thats the cause.
sometimes when i place it on the desk and i tap it or just bump it hard enough it'll turn off.
i think its more of a hardware problem then software.

That's sounds like a bad battery connection, I'd take it back under warranty {if possible} as the chance of a fried eMMC chip must be high!

[Q] Sensation power off problems

Hey guys, this is the first time I am writing on XDA although I have read and followed many of the threads on it.
My phone suddenly decides to shut off with no reason and the battery level go crazy. I would reboot the phone and see the battery level go back to normal. I has happen while listening to music or even answering a call.
I had this problem on ever since my device received an over the air update from Bell. (Mind you I am not a different provider: Telus).
Since then I S-OFF, ROOTED and started installing custom ROMS and kernels. The problem seams persistent... I even exchanged batteries with a buddy of mine who has the same phone and had similar problem to mine. Not sure what to do.
Any suggestions?!

I have had this problem off and on since March on T-Mobile USA with a phone purchased in June of 2011. Intermittent shutdowns, reboots, crazy battery levels, etc. In the end, anything that increased the battery drain even a little would cause the phone to shut down. After several calls to tech support, and a visit to a retail store, I finally got a warranty replacement for the phone. No other battery replacement or software fixed the problem, including the OTA 4.03 update. My speculation is that the battery voltage sensor was faulty.
The replacement unit is working great (so far.)
In summary, if you are still in warranty, flash the stock RUU, restore S-ON, and go for a warranty exchange.

I am going to try the try the trick with the battery push trick. If this is the case, I will be EXTREMELY happy. If not, I wonder how will I be able to bring the phone for warranty on bell since the phone is on a different network.
Any way, I will post an update to see if it fixed the problem!

so ,how does it going..?
So far not a single restart. I will have to wait a few days before I can confirm but my phone was not restarted since last night, when I did the little trick. My phone also charged faster during the night (it used to get stuck at 70% and then go extremely slow). I don't know how this is possible or if its a placebo effect but so far it seams to work. I will know for certain in the next two days.

help and no i am not crazy

s3 turning off randomly requiring battery pull to restart. here is the breakdown to date problem occured,verizon tech sent replacement phone, that phone did it so sent it back and kept original phone, replaced sims card, problem still there, replaced battery, problem still there replaced phone again, still there, replaced sims card and battery again,guess what phone is still shutting off randomly, stock rom,factory mode (no apps)nothing not even email linked all software ota up to date. all is documented by verizon and and sumsung but everytime i talk to them all i get is the same old we can send you a like new phone after all the resets and ect., i dont want another s3 that is reman wich i know does they same thing and i didnt really want to exchange what i thought was the best for a droid wich verizon wants to do and sammy wants to send reman. i have already had two other reman phones that do the same thing. now here is the kicker i own 3 total s3's and now guess what one of the other is doing it now too. is there anybody else having this problem? is there a way to track what is running when it shuts down?would a different kerrnel help? would a different rom help? could this be my account with verizon? any help at all i dont know what to do?

Try another rom although it sounds like an app. Can't be the phone on that many of them. You only one reporting this problem so has to be something you are putting on phone.

both phones are doing this on stock. no apps installed
My friend had 8 replacements through verizon before he got a good one. So try a couple more times maybe. I know it is really inconvenient but honestly the GS3 is the best Android on Verizon right now (arguably atleast) and they probably won't let you trade up to a Razr HD Maxx which is the only one I would recommend.
I'm having the same problem apparently. I just bought this phone used and activated it monday night. That night, i plugged the phone into the charger while i slept and the phone shut off overnight. Phone wouldnt turn on with the power button - required a battery pull to restart.
Going through tuesday, the phone worked fine. However, in the evening, the phone was idle for a few hours, and when I went to check it before going to bed I found it had powered off again! Required another battery pull to restart...plugged it into the charger, and went to sleep. When I woke up, I again found (for the third time) that the phone had powered down, and required another battery pull to restart.
Going into wednesday, phone is working fine. Then I leave it idle in the afternoon for a few hours during work, and when I get ready to drive home, I find it is again powered down, requiring a battery pull to restart (fourth time in less than 2 days).
Now I go to visit verizon, and the rep tells me (after I think he was looking through some company forums for answers) that I should try clearing the cache from every app, since maybe the data was corrupted during my OTA update to JB (which i installed monday night), and some app was causing this problem. So I do that, and the same thing happens again overnight...battery pull etc...
I'm figuring next I'm going to do a factory data reset, possibly tonight. This is supposed to be my sister's christmas gift! Hah...trying to work the bugs out before tuesday. Any thoughts?
Starting a post with I'm not crazy sound like something a crazy person would say.... just saying.... But I agree with the earlier post that it could be app or rom based and only effecting the screen. These are the options I see you having:
1. Try freezing any apps you've installed one at a time and see if it stops
2. Make nandriod and try another rom and then come back if that doesnt fix it
3. Try this thread to clear everything and upgrade http://forum.xda-developers.com/showthread.php?t=1984436
-This method formats internal and external sd card AND bumps you up to rooted JB in the process. Use VRBLK3.
4. Get a replacement phone

These options might work for the OP, but only #4 could work for me since i'm not rooting this phone (its for my sister). If I find a fix for my issue, i'll post here.
Are you guys using an sd card? If so it might be a corrupt file that the system goes over and gets stuck on, messing the cell up. Did you try making a backup on pc, formating your card (fat32) and putting you stuff back on it? Or take the card out and see if you get the same problem without it. If you're going thru all the replacements then its gotta be something that you use in common with all of em. GL!

How to check if you have stealthy random reboots. Post results here.

My Z3 sometimes does "stealthy" auto reboots when not in use. The system crashes and does an auto reboot but not a full one because the phone won't ask for the sim pin code, it will reboot to the lockscreen so unless you're looking at the phone while it happens you won't notice. If you're lucky enough to catch the reboot, you'll notice the screen suddenly lighting up, and the boot animation will play, then the phone will go back to the lock screen where you left it. My phone does this a couple of times a week, most of the times I don't catch it but there's a way to tell: go to Settings → About Phone → Diagnostics → SYSTEM INCIDENTS
If it shows 0 this means you haven't had a reboot in the past 10 days. Right now on mine it shows 1 which happened during the night (so I didn't catch it happening). I always have 1 or 2 in there, I'm not sure if it always happened, but I started noticing it after Lollipop, and factory reset didn't help.
Please let me know if you have any "system incidents".

Hi Mark
I know this phenomenon on custom Roms or when using a custom kernel.
I think this is called a hot - reboot, kinda, because it's not a full reboot.
If you're using w custom kernel this might be the reason, or the settings of the kernel.
I can't check what you requested because I'm using the concept rom atm.
But I'm quite sure I don't have this issue, as I remember from kk days that the notifications are gone afterwards and I think this would go for lp too, and I didn't notice so far (on this rom).
But I did have had random reboots many times at different set ups of course. It can also occur on certain stock kernel settings or root apps I assume.

My phone is completely stock and I still have these weird reboots. Before I do another factory reset I'm trying to understand if other people have them (and then not bother with a factory reset because that would mean it's a firmware issue) or if I'm the only unlucky one who keeps getting them. Anyway, I was considering getting my phone serviced, I noticed the glass is a bit misaligned and I have a dead pixel, I called the service center and they said both issues are covered by the warranty. Might as well add random reboots to the list, maybe they'll get me a refurbished phone, mine has a few marks on it.
I factory reseted my phone and then sent it in for repairs, most likely got a refurb too since this one looks brand new, and I still have those "system incidents" happening early in the morning when the phone is just resting on my table.
I don't like begging for replies but please if you stumble upon this thread just drop a line saying if you have them or not. At this point I can't be the only one.
Also I'd like to know if there is any way to consult a log or something that would tell me why it happened.
I used to have them on kk, but they stopped. Mine would only happen at work, which led me to believe it was network related somehow... As if a spotty signal was heating up the phone or something. They stopped as randomly as they started.

I factory reseted my phone again after messing with the concept rom, and guess what, not even one day passes and the piece of crap reboots out of nowhere like always. I'm so mad right now, I only have 3 thirdparty apps installed, poweramp, the app from my mobile data provider and waze. I will start to try and get rid of this phone now, this is absolutely ridiculous.
I have exactly the same problem. Started after installing LP. Had someone found a solution?

Wait, is this happening on the Concept ROM? Because if so, you do know that's an unfinished ROM, right? Not meant to be a daily driver?
Clean flash the latest stock LP and go from there.

Dude, read the post again. It's happening on stock lollipop with literally no mods installed. I kept the concept rom for 5 days and it was absolutely stable for those 5 days. Stock lollipop reboots at least once every 10 days, but usually twice.
Here's a recap: I had the phone for quite a while now, I don't remember if I had reboots on KitKat, but I definitely have had them for the past 2 months or so. Meanwhile I got my phone refurbished because I had a dead pixel, it was already rebooting when I sent it in, got it back factory reseted and hardware refurbished and the reboots continued once I started installing all my stuff. Now I installed the concept rom to check it out, went back to stock lollipop with a full factory reset via PCC and after a day with pretty much nothing installed I had another reboot. The only thing that was kept during all this time is my 16Gb Class 3 SanDisk SD Card and my WIND (IT) nano sim card. I've decided to buy another SD Card anticipating the Android M memory unification feature, so I bought a Class 10 uhs3 32Gb SD Card from Kingston (which by the way isn't reaching anywhere near the declared speeds of 80/90mb/s, it only reads and writes at around 35 on the phone, I made a thread about it, maybe the phone itself can't read that fast), and I've been using it for a day now. I had no reboots yet but I had some weird app incidents under diagnostics, one from photo analyzer service and one from backup and restore (I hope they happened when I was still messing with the memory card in and out, because I didn't use any of those apps).
Here's a thread I made on the official forum:
https://talk.sonymobile.com/t5/Xper...oubleshoot/m-p/1057964/highlight/false#M26160
By the way, I still don't know if these reboots are rare or if everyone has them. Too few people have commented on whether they have them or not, while this thread has 447 views. If even 10 people commented saying if they had reboots or not I'd be able to rule out glitchy firmware. A friend of mine has the Z3C and he said he has no system incidents and his phone never rebooted.
Still getting soft/stealthy reboots
After doing a complete repair via pcc, I did not put a SD card back in my phone and only installed my google account and apps... No 3rd party apps. It goes for a couple days and then starts doing a reboot usually once every charge and mostly in the morning. The battery usage graph shows a pretty significant gap as if the phone was off but not completely off. Then I find system incidents in the diagnostic app but it only gives me the date and time of when it happens. No other information. Kind of useless if you ask me. This has all started after updating the official LP build . 200 firmware. Sony needs to investigate this became it's happening more and more for people on 5.1.1
I have a locked bootloader, stock kernel, rooted, xposed, dual recovery, tricked out rxz experience ROM with 85 apps (it includes 17-19 xposed add-ons) in addition to 102 system apps, no random reboots at all. I keep an eye on phone diagnostics, system status (temperatures, etc.) like a hawk.
So guys if this happens at you at stock rom , my suggestion is ask the service for replacement maybe.

I am currently doing a test after repairing via pcc, installing a new Google acc, only important updates to apps I use that come pre-installed. So far it's been 5 days and no soft boots or incidents in diagnostics. Although it means nothing because usually after about a week or so is when the issues come back after doing a full repair or factory reset. I guess time will tell. Otherwise everything seems to be working great, especially battery life.

Google pixel keeps crashing and restarting. What should I do?

I was watching a video on my pixel when suddenly the display freezed and turned off. Since then it has been restarting and crashing again and again. I have already done factory reset. I am unable to attach image here which would have given a better idea of the problem ibb. co/ jDdU6b . Remove the spaces in the link to see the photo.
Instead of a factory reset have you tried flashing the factory image via fastboot? I would attempt to backup what is important and run the flash_all.bat with the file unaltered. This will allow the image to be flashed and all user data would be wiped giving a clean install.

Just for humor, it is the same concept!! https://youtu.be/kKAjay0iWwI
Bro, let me know what you find out because this ****ing phone has got me sick and tired of these reboots. It just ****ing reboots at random times and even when it boots up after a reboot it will freeze and reboot again. Honestly, I have never said this to anyone because I am a hardcore nexus user but **** this phone, google really ****ed this one up.
I been having this issue, and preformed a factory reset on Jan 1. I cant say I have seen it re-appear. I am 7.1.2 by the way. If it is across the board with 8 and 7.1.2, then it may be some wonky google app that is common to both. It was not any specific application that it happened on either.
I just did an RMA, my warranty ended in dec 27 and they still sent me a new one. I hope the new one doesn't have problems, it probably is a google app.
Return it before your warranty runs out. This happened to me on december 15th. My warranty expired nov 17th and google refused to do anything and ubreakitifixit cannot fix it. This is a known issue, but google won’t stand behind their product. Eventually your phone will shut down and never turn back on.

I wanted to update this as it is possible I might have stumbled across something.
After wiping it and restoring some apps, I had no issues with it until the week of the 22nd of January. I installed one app and it started to reboot randomly. That app was Android Pay. Once it started to happen I uninstalled it, and have not had any re-boots since again.
Best Regards
This just started happening to my girlfriend's pixel. Bone stock, never rooted. If you even have a HINT that your phone is rebooting for no reason, I suggest you send it in for repair as soon as possible. Her phone now just bootloops, and you can't boot recovery mode either.
Google support said that the warranty expired in October, and so they told me I can go pound sand.
Well I can call UbreakiFix... I got a quote of ~$500 to replace the motherboard + screen, and no one else sells it that I can find.
A flagship phone lasting barely more than a year is not acceptable to me. Google should be offering me a replacement device, and I'm rather pissed that they aren't.

Yeah man same thing just happened to me, like wtf
Same here. Just bootlooping... Thanks google
This is what I get for updating my damn phone, Same problem here.
Now happening yet again to my Pixel and this is the 3rd handset I've had in 18 months. Now need to send this back to Google so that'll make 4 Pixels I'll have had before my contract ends and I can escape to a handset that works.
This problem seems to be pretty widespread. Mine Pixel’s been doing this for a while now - sometimes it’ll go days without me at least noticing a reboot, other times it will happen so often as to make the phone useless. I just tried a factory reset - anyone know if there’s a permanent fix to this? It sucks when I’m in the middle of a call and then all of a sudden the phone shuts down and starts rebooting.
