Hi all,
So iv had 2 nexus 6s so far (the first's screen cracked so I had it changed) and both have several issues, most notably,
- random infinite bootloops on restarts. Phone goes to 'android is starting' pages, and then restarts the whole bolt process again
- I have to restore phone to a backup, whereupon phone works for a bit, before
- infinite bootloops start again.
- also, Google camera refuses to work.
I have absolutely no idea why this is happening, same issue on 2 separate phones, more less. Can someone please help me shed some light on this? This very expensive piece of hardware is nothing but a table ornament at this rate.
Rooted?
You mention in the title that the phone is rooted. To be able to discount hardware errors, have you tried flashing a factory image to set it back to stock? If the same problems continue, then I suggest that you return it to Google. I did this myself when the back of my N6 started to peel and the process was painless, since they send you the new phone before you return the old one, so you lose no airtime.

Yes, as mentioned, flash a factory image to rule out any software issues. However, it is most likely hardware failure. Especially the camera fault. I've noticed this is becoming a rather common issue lately. So, you should probably RMA again.
Thanks guys. I was just concerned as I unlocked the bootloader and rooted the phone almost immediately after I got it. If I try to RMA it, they won't cry foul over a re-locked boot loader,will they?
Also,I have a feeling this might be an OTA that is acting up. It appears that loads of people have had issues after installing an ota (I did this before unlocking and rooting) so I'm going to try to flash a factory image. Thanks guys
Hello everyone,
as an update, I did exactly as dahawthorne and evolution_tech said, and re-flashed a factory image. However, i found it extremely strange that both my nexus 6s were experiencing the same issue so i did a little research.
Turns out, many users from 5.1 have been experiencing issues with changing their dpi in android 5.1 and above. Because I'm not all that familiar with build.prop and using adb shell (tried using it once, it wouldnt work properly so i just gave up), im not going to bother changing my dpi and it works all fine and good now.
To anyone else experiencing the same issue, check this page out: http://forum.xda-developers.com/nexus-6/general/dpi-conflicts-lmy47e-t3061261.
Cheers
Yep, well known issue.

At least I think this is. I have recently moved from stock to Asylum's CM10.1 but did flash a known safe kernel before any wifing occurred so I do not think this is the standard EMMC bricking.
The onset of this was gradual - phone reboobed itself a couple of times (that I noticed) but this was no huge deal for me, then a few days later the screen digitizer stopped working and I had to take the battery out - from there it degenerated fairly rapidly with more reboobs, more often returning with the digitizer not functioning and finally it is at the point where it will not boot - stuck at the loading logo.
I can reboot into recovery (CWM 6.0.3.2) but can't do a lot there - fleshing a new ROM errors out saying the package is invalid or crashes (often with a brief flickering of the screen in either case).
I can run through hg42s partition scanner - if it completes it does so without report a problem otherwise it crashes, it's about 50/50 which although it seems more reliable if mains power is connected.
If I leave the phone in CWM it will eventually reboob itself after a few minutes.
I haven't seen any magic smoke escape.
I never experienced the EMMC brick so I don't know if it was progressive as this seems to be but I get the impression it was not - and I can't rule out the same sort of problem even if the original cause is different but at the moment I am unsure about the best way to progess - I will at some point pop over to Samsung's store but ideally I'd want to get to the bottom of this with the help of the community.
So any ideas? Does this sound like a corrupt partition somewhere? Thermal sensors triggering shutdowns when they shouldn't?
interesting, try to catch the evnts in the logs, use elixer/logcat/android tuner for that.
Check the battery dude.
I had similar problesm due to bad battery.
Phone was closing itslef. And before it closesi thescreen was turning crazy
Then no boot at all....

Thanks. Did your problems occur even if the phone was on mains power? Does the battery have enough 'smart' features to affect the phone even if it is not required for powering the device?

I was outside when faced such a big problem. It was happening before like reboobs and stucks on logo. But after i took out the battery for 15 min I was able to boot the phone.
However, eventually, one day phone got stuck with a flickering screen and then it never booted. Tired nandroid restore. Did not help. Changed kernels etc. It was no good either. Then I changed battery. Did not work again Then made a factory reset. It worked. Using it without any problem now. But even at that time I was able to see my files in the phone via Qadb. This could be your case as well.
Try changing battery if it is older than 9 months. Make a full pit fresh Stock install.
Then Reboot. I hope t will work

Yup. This was indeed the problem - new battery in and after a few repeats of the same behaviour it kicked into life and has been fine since.
Thank heavens for replaceable batteries.

Hi there... new to the forum, but long-time reader, especially over the past two days since I dropped my AT&T HTC M7 (flashed to GPE) on cement and it pretty much died.
I'm out of ideas and could use some help. After the drop, it was stuck in a boot loop, but I was able to get to hboot with volume down. From there, I can access fastboot, but recovery or factory reset options just trigger the boot loop again. During the loop, it shows the Google logo (or HTC logo when flashed to stock) for 15-20 seconds and then reboots. Physical damage to the phone is not too substantial, and I have unfortunately extensive experience opening it up from repeated attempts to fix the purple tint issue with bad modules from eBay, so I checked inside and everything is intact.
Over the past two days I've flashed RUUs and recoveries like crazy, downgraded and upgraded hboot, changed CID, etc. I can oem lock and unlock... fastboot kicks out an error when I do it, but the status in hboot is changed when I reboot into the bootloader. Flashing ROMs and recoveries works like a charm, so does erasing cache. What I mean is that the process works exactly like before in fastboot, and I can see the splash screen logo change, so I know it's taken effect, but NOTHING gets past the boot loop. I am thinking the drop resulted in a corrupt partition, but since I can't get into recovery I haven't been able to find any way to do anything about that. If it was physically broken, it just doesn't seem like I would be able to do everything I can. I initially thought maybe it was a busted/stuck power switch, but that works perfectly navigating hboot menus and nothing ever auto-selects or anything like that, which I would expect.
Aside from the fact that I really like this phone, and that I really don't want to have to pay to replace it, I feel attached to it since I've dismantled it successfully to repair more than once and flashed ROMs many times in the past without issues. I've just run out of ideas, and of course I can't go on much longer without a phone.
Does anyone have any experience with this or hunches I can try out?

yeah try a new motherboard yours is broken, really it's hardware damage no amount of flashing will fix it

Thanks clsA. I'm surprised by that since in my experience a broken motherboard results in a much more substantial and obvious failure, but I guess the point is moot if I can't get into recovery to try anything else.
There isn't much of a market for new motherboards, and my experience with eBay sellers for oem components on this device makes me think trying to replace it there would be a fool's errand. I guess I could buy a used M7, but on the other hand the damn thing has basically been nothing but problems. The defective camera turned to garbage in under a year and one drop killed it? Unless anyone has another suggestion, I guess it's time to cut my losses on this thing. I may feel a sentimental attachment because I've nursed it along so much, but damn... a phone is a phone and this one has been a LOT more problematic than any other one I've had.
Gotta thank you again clsA! Your words of doom made me feel that extra bit wreckless, so I decided if the phone was cooked anyway I might as well tear it down and try whatever I could... firmly reseating cables and squeezing heatsinks, etc. Low and behold, I reassembled and the problem is fixed! I'm not sure what the exact issue was, and I won't be surprised if it comes back at some point down the line, but I'm back up and running tonight and that's a hell of a lot more of a victory than I was expecting.
So... it wasn't a motherboard issue, but it was hardware related.
I should have posted on here when this first happened. I love xda!

That's great, I'm glad you were able to fix it
First, I will say that i'm not a developer. I am familiar with backups, rooting and custom roms. I'm just at a total loss with a total loss phone :/
So here's the rundown of my issue/s with my Moto Turbo (XT1254)
The phone is completely "unmolested." My phone is stuck in boot loop, currently. I did bust my screen a few weeks back but it had been working just fine. I picked up my phone to check texts, and I saw the "updating 24 of .... apps." Once finished, it's been stuck in a boot loop since. (Odd thing, my screen now shows split Moto image when trying to boot. Ex: a slot machine with only 2 roller wheels that wont match up)
I have tried to clear the cache several times with no luck of it booting up correctly. I do have files that I was trying to recover since they are not linked to a cloud account, and was trying to avoid a full on reset. I did, however, get frustrated and even tried to reset it back to full factory settings. That did not work either. So, all this being said, I'm back to trying to recover my files (my daughter's first year of life, family stuff, etc), since I cannot get it to even preform a factory reset. Does anyone have some guidance or same issue on this matter? Again, I am trying to salvage my files now while stuck in soft brick / boot loop status.
Thanks any and all who can help me with this!
******* Solved********
I have better diagnosed and fixed my own issue. I'm sorry I don't have pictures or video to better document what I did, but in short, it was as simple as replacing my damaged screen/digitizer, with a new one.
My theory was that during the update, the phone checked over it's systems and found that the digitizer was non-responsive in a few very small areas (this I already knew from using it a couple weeks with the screen damaged) and it somehow caused it to go into a boot-loop. My experience with fixing Playstations 3's, helped shed some light on this for me. I had a PS3 i thought was in good working order, updated firmware to it, and it bricked the system. Come to find out, the blu-ray laser head was no good. Upon the firmware doing system checks, it found that was bad and ended up bricked.
I did replicate the problem by switching the broken screen and new screen back and forth 2 more times after the initial fix. Upon disassembly, (youtube for teardown vidoes) you disconnect the battery from the logic board anyways, so when you boot the phone up, it does a app check and system check again. Every time the damaged screen was connected to the logic board and then powered on, it would end up in boot loop. The new, undamaged screen, would do the required checks, then boot up like normal.
I will do my best to borrow/rent a camera soon, so I can make a short video to show this works.
I'm not going to promise this will work for everyone but with replicated results, hopefully it's a fix for someone!
I hope
Hi all,
I am completely running out of things to try and do now.
After installing Android 7 on my Note 5 I had the strangest issue that i in general have never seen on a phone. The screen is simply black (which isnt that strange) and the phone is fully functional. Bare with me, after reseting it multiple times so it would finally come on the screen goes crazy and turns goes into so many colours (if it turns on that is). Its either that or jumps all around the phone, quite literally it glitches out completely. Its like one of those virus cut scenes you see in movies, it goes different colours, glitches out, jumps around and completely misformats.
From the beginning i knew this was not a broken screen.
So far i have tried.
1. Factory reseting the phone. That gave me about 5 minutes of normal use until i locked the phone and it wouldnt unlock again.
2. Factrory reseting multiple times... again to no avail, it would work for short periods of time and glitch out again.
3. Reflashing stock Android 7 in Odin. - No avail.
4. Flashing Dr.Kretans Rom... worked for 1 day which made me so happy and think that the problem was solved but then the same problem persisted.
5. Installing Arters Kernel.. (arter97-kernel-n920cig-22.0) Nothing... literally did that today and still NOTHING
6. Re partitioning. Quickest process and no avail.
In more detail, if the phone does sucessfully boot, and bare in mind sometimes it takes more than 2 hours to get ANYTHING on the screen (including recovery which doesnt boot up either until the initial apperance of something on the screen)
I tried taking the phone to a phone shop before doing anything myself and since in England this phone was never released theyre refusing to touch it. I tried calling samsung and they dont want to do anything either cause its not a UK variant.
Could someone please tell me anything else i can try. I feel like im totally running out of options here.
My phone details are as follow
Galaxy Note 5
SM-920I Singapore Singtel Variant
Running on 6.01 (i downgraded from Kretan)
And the kernel is the one previously mentioned v.22.0
I would appreciate anyone's help or suggestions so much at this point. All these problems started since the 7.0 update a few weeks back :/
Oh its also running TWRP recovery (arter97-recovery-n920cig-22.0-twrp_3.0.2-0.tar)
Hi!,
I'm a long-time reader of this forum, but this is my first post. In the last few days, something happened (I wish I could pinpoint exactly what) where I ended up restarting my phone and it entered a continuous boot loop. The phone was receiving updates per normal and may have received an update not that long ago that required some kind of restart, but I'm not confident about that. Either way, the phone was restarted and it entered into a permanent boot loop.
Before restarting, I'm confident the "ear sensor" that turns the screen off when I'm on a call as functioning. I'm also confident the auto-rotate functionality of the phone was working perfectly.
After I tried to factory reset the phone from the power-volume reset options, I actually ran into a TON of trouble trying to get the phone to properly reset. It tooks me countless tries to eventually get the phone to start after resetting it over and over again. I was stuck trying to get the phone to actually move through the setup steps. SUPER frustrating. I actually went to sleep while the phone was somewhere in the middle of setting up and when I woke up the phone somehow eventually made it through some setup steps.
I'm now using the phone as I normally would, but it's very odd. The phone is a LOT more unstable. At least 3 of the sensors I had working have just completely stopped working.
The phone is in otherwise perfect condition. I'm genuinely confused about how I should go about trying to resetting this thing to a pure stock configuration and slowly installing apps again to make the experience what I'd want.
And no, I'm not a super power user. I am a strong engineer happy to do crazy things like flashing bootloaders and whatnot, but I'm honestly confused about where to start. I understand other versions of this device may have had corrupted persist partitions during updates -- those problems seem like my problems -- but I don't know how I should go about simply flashing my phone at the lowest level into something stock that I can try to build back from.
And obviously when talking to google support their suggsetion is that I mail them the device and wait 10 days without a phone. I'm confused about how that could EVER be a reasonable way to get a phone repaired, sigh -- phones are not toys, they're pretty critical to the day-to-day work of so many people including myself. I'm pretty disappointing with that approach from Google and I had always considered them much better than that before this experience.
Anyway, I'm really lost and I'd love to understand how to repair the software on my phone.
(You all kick ass!)

You did not provide the most important information we need- whether your phone is bootloader unlocked. Probably not, otherwise you would have already flashed it with a full Google image, which returns the phone to "out of the box" condition. You need to determine whether you can unlock your bootloader. If you cannot unlock (allow oem unlock is off and or greyed out in Dev options) then you will not be able to fastboot flash ANYTHING. If that is your case, the next best thing is flashing a full OTA image (sometimes called a rescue OTA) from recovery mode using the OTA via ADB option. This means you need fastboot/adb installed and working on your PC. Instructions on how are on the same Google dev page for OTA's.
So, my phone's bootloader is not unlocked. But I have an update for the crowd that may one day find this. I know your frustration and I can report that my phone is once again fixed.
A day (or two) after I sent this, a set of updates came down to my phone. And WebView was updated. That restored all of my sensors and also restored most of my crashing applications. It was an incredibly odd experience.
My phone once again functions. And the nightmare of owning a Google phone and talking to Google support has ended.
