Continuous Bootloop even after stock flashed - Nexus 6P Q&A, Help & Troubleshooting

Hi.
I've had numerous nexus phones and generally dont have many issues however randomly today my phone entered a bootloop. I decided to completely flash stock firmware (how i normally solve issues but no matter what I do it just continues to bootloop.
I can get into Fastboot but thats it.
Any ideas or experience of this anyone?
Thanks in advance

Gave up in the end, couldn't fix it.
google replacing under warranty

Just had to do the same thing last week. Using Uber Partner app and when I accepted a "call" phone crashed and began bootlooping. Tried fastbooting stock image but ended with "Phone is Corrupt" message and continuous boot loop before replacing under warranty. I was running August update Benzo ROM. Never experienced anything like this before and I've been flashing for 5 years now. Sorry about your device, the new one in the mail will make it all better best phone ever!

Oh god... I think my device is doing the same thing.... I've tried flashing stock through fastboot twice now. Still saying my device is corrupt. Even tried a different cable, and redownloading the firmware.

This happened to me too the same day out of nowhere. Google sent me a refurb. Battery in this replacement seems much better. I couldn't even get into the recovery.

Nexus 4 TWRP encryption with password - I think the phone is gone

So, I have read a lot about TWRP sometimes bugging out and randomly encrypting phones and adding a password to which the user either never set it up or that TWRP doesn't accept it. This has recently happened to me and I cannot use my phone and I don't know what to do.
I have had the bootloader of my phone unlocked since day 1 when I bought my phone (release date last year) and have been running PA ever since. I have never had any problems with it, until about 5 days ago, when I grabbed my phone and everything started crashing and the camera was apparently not available. I didn't know what was the deal with it, so I rebooted the phone and it entered a bootloop (it hangs on the Google logo for about 5 minutes and then it hangs on the PA logo screen forever). I went on to the bootloader and started TWRP to see what was the deal. I originally wanted to grab certain files off the phone in case I had to do a system format, but when I got to TWRP, it asked me for a password which I have never set up and I tried every combination I could think of but it always failed. Everything was encrypted and without the password I couldn't get to it. I tried wiping everything including a factory reset before resorting to a system format (which I read about it and apparently is meant to be the solution). Everything failed because it couldn't access the /cache, /data, nothing. I went on to do a system format and although that is meant to wipe the phone and remove encryptions, it also failed to wipe the /cache and although TWRP says that the wipe is successful, the phone is still encrypted, the password is still around and it bootloops. I have tried the system format like 50 times and always the same.
Can anyone help me out with this? I am currently travelling around but am at a hostel where there is great internet and pcs, so I can install drivers, toolkits and such. I actually started looking around for new phones, since I cannot for the life of me get the phone to start again.
Note: The phone was working perfectly fine, I put it down to have dinner and once I finished, I tried to use it and it started to bug out. I also read around about this, and everyone's issue gets fixed after a system format.
Any help, would be greatly appreciated, that phone is the only net device I have on this trip and it sucks to not have any way to contact anyone.
Thanks.

Don't blame TWRP for something it doesn't do.
Looks like your device have an EMMC failure, sorry.
You can try installing factory image, or last resort restoring by download mode, but I think the flash memory in your phone is gone.

I didn't mean to blame TWRP. It is just that it was when I am on it that I get asked for the password and I was under the impression that it was TWRP that did the encrypting (I am in no way a developer or even very knowledgeable when it comes to the under the hood stuff, I usually only follow the tutorials). But thanks for the reply and the link, I will try that and hopefully get the phone back working.
Also, I did read in a thread that apparently this can occur due to hardware failure, I was just hoping this wasn't the case.
This happened to me on an old phone. Not sure why. Factory image fixed it. Could be a different issue but its worth a shot.

Did it suddenly happen or did you change ROMs?
I tried a new rom for the first time and then went back to wicked 9.1, I'm thinking that triggered something.
I think I got a fix though, look here: http://forum.xda-developers.com/showthread.php?t=2588377

Nexus 7 not starting

Hi,
I recently rooted my nexus 7 and flashed TWRP recovery. One day I got into the recovery and started playing with it. By mistake, I erased my OS. I then came to know to know that i could fix it by flashing a custom ROM. I installed a custom rom successfully. I then wanted to go to stock. While flashing the stock OS, it got stuck in bootloop. It was too late so I thought to flash it the next day. On the next day, when i tried to switch it on, it did not start. I kept it overnight for charging but it was of no use. Then i went to the Asus service center, and i came to know that there was a motherboard problem. I did a little research on google and came to know that to earn money they told it was a motherboard problem. Many people had fixed it by unplugging the battery and replugging it back. I tried that, but it was of no use. I did not play with the bootloader. But now I think that it could be hard bricked.But I am not sure. So any idea whether it is hard bricked or really is the motherboard spoiled or what??
Thanks in advance

SM910F Note 4 5.1.1 Random Freezes and Restarts

Hello there xda.
I have a Samsung Galaxy Note 4 SM910F.
So what is happening to my phone is that whenever I am in any random app lets say reddit or even chrome for example. It will like freeze for a minute or two and then unfreeze.
In more extreme cases it will reboot.
So this happened randomly because I flashed a Stock unbloated 5.1.1 ROM from here back in december and everything was working smoothly and stuff. I had xposed installed and all my apps. Then in February it started with this random freeze/reboot. I had not installed anything else apart from what I had for the last 3 months.
So I restarted the phone, changed the battery and stuff to see whether that will fix it. However it didn't. So I formatted the phone (the soft type) just so I can install another ROM. So I tried another ROM, flashed the correct CP and BL and stuff and then just installed chrome and whatsapp. After an hour or two the same thing happened. So this time I factory reset he phone, like a complete wipe and I installed the unbloated ROM once again with few apps. Same thing happened...
So my last resort was to install Cyonagen Mod. After an hour or two same thing happened...
I don't know what is the problem. I read about some peoples phones emmc failing and thus the freezing, but I am not sure yet.
Please could you guys explain what I should do to fix this?
Thank in advance!
I have the same problem. Starting on mid january. I'm on stock 5.1.1 with root and twrp recovery
Tried backup and factory reset
I went back to stock after I factory reset the phone. And still had the same problems.
People say that its a hardware problem... So I guess I'll have to send it back to Samsung soon.
I think I tripped the knox. I just have to unroot and get it back once again to stock and send it back. I hope that they accept it.
i have the same problem. my model is SM-N910W8 and I bought it from 2nd hand, so no receipt and no prove of purchase.
can I still send it back to samsung to fix it?
same problem as you and now my phone died completely .
my phone was 4 months and he has not supported any longer he died naturally lol.
my operator gave me another free under warranty because the phone had a faulty motherboard and after several back galaxy note 4
This started happening to me a week or so ago and my phone just got stuck in a boot loop after it froze and rebooted. I'm on the latest stock firmware. Tried factory reset, reflashed stock firmware, nothing helps. It still reboots (sometimes it almost gets booted completely, other times it reboots after 2 seconds.
Just disable finger print. Yes that magic feature offered by Samsung is causing more hungry that happiness since S5

Many thanks. This was driving me mad for a few days, I had tried three different ROMS, completely wiping everything. I eventually went back to stock, which I'm still running and it was the same; it would run fine for a few hours and then start to lock up until eventually it would either reboot or stop responding and I'd have to pull the battery to restart it.
Just not selecting fingerprint security doesn't work, you have to force stop "Fingerprints" in Application Manager (All).
just do not setup the finger print lol. I was having those problemes too when I bought the note 4 until someone tell "do not setup the finger print" lol, not I'm a happy user.... I hope that android 6.0.1 solve the probleme

Moto X Pure issue, urgent help.

Hi guys,
So I had been using my Moto X Pure (3 months approx) and it had been perfectly fine. Except just a couple of days ago while I was on snapchat the phone suddenly shut down. While I tried to restart the phone it got stuck on the boot screen and didn't go past that. I initially tried to wipe cache partition & factory reset but nothing happened, it was still getting stuck on the boot screen.
My phone is unrooted and I haven't tried experimenting with the kernel or anything, mind you.
I left it alone for a couple of days and it started to boot up again, it was working perfectly, no issues whatsoever. But just yesterday the same situation occurred yet again :/ not while I was using snapchat but I unlocked the phone but the screen didn't turn on and it restarted by itself and got stuck onto boot screen again.
Is this an issue with the software or the hardware?
I talked to Motorola and they said they will issue a replacement phone, but I live overseas so it could be a hassle. Should I just send it in for replacement or try and reinstall the rom using factory image?
Thanks guys, really appreciate your help
could try reinstalling the factory image but if you havent messed with anything on the phone maybe its a hardware issue... i dont know
If the bootloader is still locked, i would definitely go through the replacement hassle. Should have no issues whatever after only 3 months and 100% stock.

Yeah - I haven't heard of stock unrooted phones getting their system image corrupted such that a reset doesn't get back to proper "stock". Maybe a botched OTA, but if you've got that warranty option, probably be wise to take it.
I don't know this phone and Motorola well enough to say that unlocking your bootloader and starting from scratch, as I would be sorely tempted to do in your situation, won't void your warranty option.

Anybody else have a main board failure? Here is my story.

Last week I was minding my own business, doing usual stuff on my phone and the device spontaneously rebooted into a bootloop at the Google logo. So I think "OK, no problem... I can try wiping cache/dalvik or at worst I have a recent nandroid backup" and proceed to reboot into recovery... except that it still hangs on the Google logo. Stuck at work I did a bunch of googling and found one other user who had the same thing happen recently.
When I got home I tried to fastboot flash TWRP again... but alas was still stuck at the Google logo. Next was a full flash of Google stock images, but that did nothing either... so I relocked the bootloader and had my provider (TELUS) send it in for warranty repair. I just had it returned with the repair stating the main board was replaced.
I have noticed a few users posting about being stuck on the Google logo and this concerns me a bit, as it almost seems like there may be some inherent hardware flaw causing the issue.
So I'm throwing the questions out there: Has anyone else had similar problems and is this something we should start to be concerned with?
You're not alone buddy. I'm in the same boat. Have sent mine for repair yesterday.
Thats discouraging news. How long have you guys owned the phone? Did you buy it new?
I love my 6p but if enough of these units are defective they should probably be recalled. Hard to gauge if its an anomaly or a serious issue. Hope for the former...
I think I may have the same problem. My phone wont boot past the logo at all. IDK what to do at all.
I have the same problem, stuck on the google logo, I already wiped the cache partition and nothing, did a factory reset and nothing, what else can I do??

Check if you can boot twrp. If you're not successful send the phone for repair. No option available to recover from this king of hard brick yet.
Weird thing is anything and everything is doable in fastboot. Moment you try to boot OS or recovery, gets stuck indefinitely in Google logo and reboot.

this exact thing literally just happened to me on Thursday. I was fully stock never unlocked the bootloader or anything. phone suddenly started looping, tried wiping cache, doing factory reset, finally went nuclear and unlocked the bootloader and flashed system images. nothing worked. warranty replacement is enroute.
I bought it on release day.
Old issue with Nexus devices. Has been going on since Nexus 5

I got the phone new from TELUS at the end of December, so about 6mo before I had the issue... Thankfully fastboot still worked so I could return to stock and relock the bootloader before warranty claim...
Starting to wish I had done the insurance option if these things are failing after 6mo and I'm on a 2yr contract

I'm also having this issue, but I get stuck at the boot animation instead.
I have Nexus 6P, Stock Android 6.0.1 July, SuperSu v2.74, franco kernel r23, Xposed v85. Everything was running fine when suddenly the phone rebooted and got stuck in boot. I reboot into recovery, deleted the /data/data/de.robv.android.xposed.installer/conf/modules.xml, flashed xposed unistaller zip, cleared cache and rebooted. Still stuck in boot. I reboot into bootloader, flash boot, system, vendor image of July factory image and reboot. Still get stuck at boot. This is happening for the third time to me. Happened in May, in June and now in July. Only thing that works is restoring a nandroid and then again flashing the latest factory image. But that way, I lose days / weeks of data, depending on when that last nandroid was created.
That really sucks, but doesn't sound like a hardware failure from my understanding... I lost ALL my data when I had to send it in, since my failure resulted in no access to the internal memory... Lost a few pictures which was a real bummer, but lesson learned and now I'll be backing up my memory more frequently and also setting up cloud backup for photos

It's likely a software failure. When you flash via fastboot, do you reboot back to bootloader after flashing radio and bootloader? If not then that's likely what's causing the fast boot method to fail for you. The first time after I did a complete fastboot flash of the software I fell asleep and woke up in the morning to my 6p still at the boot screen. When I re-traced my steps I found out that my mistake was not properly rebooting after flashing radio image, then doing another reboot after flashing bootloader.
Got my device back. Same exterior. Was told that motherboard was changed. I could notice that from fastboot.
eMMC changed from Samsung to Toshiba
DRAM changed from Hynix to Samsung.
My device joins this list. Gonna send it for repair tomorrow and hoping it is covered under warranty.
Additional update. I know I missed the bigger scheme that changed. My IMEI.
Just curious what happens if I restore my previous efs partition backup after backing up current.

my phone randomly locked up, then rebooted today. But when it rebooted it was stuck with the white google logo flashing. I can get into the bootloader mode, but from there, choosing recovery or anything else gets back into the white google bootloop. I called service and they're sending me a replacement. Phone was stock with a locked bootloader.
