Random boot loop, can't get anywhere in recovery

I was on the latest CM13 nightly (was waiting a bit to go to 14.1) So I went to bed last night and my phone did a reboot as I was setting my alarm. Didn't think too much of it, crap happens. I waited for it to come back fully into the OS, which it did, checked my alarm. Noticed something strange I got the CM Updater notification in the statusbar ("There are new updates available" - CM14.1-12-02 or something), which I thought was weird that's the first time it's said that, and I've checked the CM Updater before and since the 14.1 switch there's been nothing there. As it should, I imagine, not try to update major versions like that. Anyways I dismissed it and went to bed (this entire thing is PROBABLY entirely unrelated, but I found it's timing interesting at least).
Woke up a few hours later to my phone getting really hot, and stuck in an infinite boot loop. It never gets passed the first Google screen. If I let it go it'll sit there for several minutes and maybe reboot. I was able to get into the bootloader, choosing Boot Recovery though sends me back to the Google bootup screen where it never progresses, doesnt have the blue text in the top that says booting into recovery..
Was able to get into the phone with fastboot so I tried flashing the latest recovery I had installed TWRP-3.0.2-2-angler. Still wouldn't boot into it, sometimes it would get to the TWRP recovery loading page, and then sit there for a couple minutes, then reboot.Tried flashing it a few times with fastboot with no success.
Erased userdata with fastboot, then did a full factory reflash of several images, MDB081 - MTC20l (factory images I know I've used in the past to recover, had them saved). Rebooted and I still can't get into the OS (stuck at first Google logo). Interesting the stock recovery though loads.
Flash an older TWRP recovery I had saved twrp-2.8.7.2-angler . Was able to get into recovery finally - kind of. Sometimes it still locks up and wont let me swipe to enter TWRP. The first time it let me in it asked me for my decryption password - I didn't have a password - had a swipe and fingerprint setup only. Got in again and first thing I tried doing honestly is erasing (formating) all my data, thinking if I'm going to have to warranty this phone or sell it broken, I want to make sure my data is wiped. Also I figure after that I can try to reinstall CM etc like I would a completely fresh build. It complained about not being able to mount the partition and locked up in TWRP then eventually auto rebooted. Got in again and tried to do a basic wipe, it said it cant find /sdcard then said it wiped, and then froze, auto rebooted again after a few seconds.
To note : All fastboot commands seem to execute with "OKAY" status, no errors reported anywhere, it always finds the device too.
I can't seem to get anywhere with this phone. Everything I try to do in recovery is met with freezes and reboots. It seems like maybe the internal emmc has taken a dump.
Problem is I'm literally 3 days out of the 1 year warranty from when I received my phone, and having tried to work with Huawei support previously, I'm 100% certain they won't help. I came across a few threads on here similar to mine recently without any real resolution other then RMA'ing it. I figured I'd post here for a last desperate attempt if anyone has any other suggestions, because I don't know what I'll do. The Pixel XL is ungodly expensive, and conveniently out of stock. And I don't think I could talk myself into buying another Huawei anytime soon after this.
Any suggestions?

It's an ongoing thing with these 6P's and 5X's. Some have been able to fully recover and others like myself were not. Here is a guide that might be able to help you if you haven't come across it yet. Good luck..

Thanks. I came across that. I tried flashing MMB29P as well as several other factory images without success. My problem now it seems no matter what I flash I cannot get back into recovery anymore. Even if it's stock or if it's TWRP (any version - including 3.0.2.0 as they suggest), so I don't really get passed step 4-5 in that guide. I guess she only had so many reads left in her, sigh.
WEIRD @ warranty link. It says from my S/N that it's valid until 2017-02-17. I don't know how, I purchased it 2015-10-22, it shipped 2015-11-24, and I got it 2015-11-30. Unsure how/why that would've gotten extended until February. I'm concerned they'll get it back then deny it once they figure that out, or figure out it's been unlocked/flashed. When I first got the phone i had issues with it charging, I narrowed it down to the USB C->C cable being faulty, and contacted Huawei. They absolutely refused to replace just the cable. Said I had to ship the whole phone back and it'd take AT LEAST 3-4 weeks to get it back. I argued with several people on the phone there (their support 100% refuses to give you their name or transfer to their supervisors btw), and finally asked google support to pull some strings and get in contact with someone there to replace a simple freaking cable - no one cared at all - spent several hours trying and got nowhere. I'm /done with Huawei. I think my best bet is to probably find out how well that American Express extended warranty claim works, I've never actually had to use it before. IDK what I'll do after that. Sad this is a common problem with these phones exactly one year out, so even if I wanted to buy a used one on eBay I'd risk the same thing shortly thereafter.
I'll keep the phone powered off for a while and try some more flashing later see if I can get back into recovery to try the rest of his steps in that article. It's not looking promising anymore.

Well being that it's a known issue, like I said, I myself ran into this fiasco, had phone rooted and running custom rom. I myself couldn't get into recovery but was able to flash all factory images and relock bootloader manually. I then called Huawei and played dumb telling them that I had updated my phone to the latest firmware via OTA and then it went into bootloop. They never asked if it was unlocked and I never volunteered to tell them either. I had bought my 6P through Best Buy and still had receipt Incase they'd asked for it which they didn't. All they did was ask for IMEI # along with Ser # and verified that it was still under warranty, then they emailed me a return label. I shipped phone to them and in a matter of like a week or so I had a brand new device in hand. Build date on it was August, 16, 2016. So far running good but let's see for how long.

Hmm interesting. Maybe their US support has improved since last year. So it was brand new not refurbished? Did you get the full retail box set? I bought mine directly through Huawei, so I would like to think that they would have accurate warranty data, but perhaps not. I will consider RMA'ing it to them if it's really a new one. It's either that or a 550$ refund from my credit card company. I haven't tried fastboot lock yet, will do that when I give up on all else lol (and need to return it), but hopefully that will work if the rest of the emmc is hosed.

Yeah, mine came in a new box, sealed like day one. I was surprised thought I'd be getting a refurbished device but I can honestly say it was a brand new one. And I don't blame you on trying to get the device to a working state. I tried everything and it's mother before giving up and finally relocking bootloader and sending it in.

Just called them. They won't accept it back without a proof of purchase. I have to send in the proof of purchase before they'll approve the RMA and then I get the shipping label/information. And "they can't look it up by S/N, doesn't matter if the website says it's in warranty". LOL. Sounds about right from what I remember of their support. They say their website is inaccurate, and cant ever verify/lookup that I bought the product directly from them. Maybe I'll try back tomorrow to see if someone else will help but it's unlikely from the sounds of it. She did say this is very common problem however, knew all about it.

Damn, That truly sucks..I would definitely give them a call again and see if I get a different rep. I was lucky with the one I got, he basically knew it was an ongoing thing and really didn't give me a hard time. He didn't even ask for a receipt, about the only thing he asked was that if the bootloader was locked or unlocked and when I told him it was locked, he then proceeded with the RMA procedure.

Yeah I played dumb and all, didn't help. She didn't ask me any real questions she was convinced of the problem just from my description. She also said it's 12 months from the date I purchased it and not when I received it in the mail (so since they took 5-6 weeks to get it to me - preorder madness - I don't get that time back in the warranty) lol. Not like it matters now, just to further comment on how crappy their support/warranty is (in my experience).
I'll follow up if I have any more luck unbricking the device or warrantying it for that matter.

Good luck on either with the warranty or bringing it back to life.

I also have problems such as your support Huawei says four weeks of waiting

Got a recovery image to boot finally (after like 10x attempts at flashing one). Tried doing the nandroid backup as that guide suggests, says it cannot find/mount /sdcard and freezes/reboots. Tried going into wipe -> advanced and repairing internal storage and data and it was an invalid partition or something. Tried repairing system and it locked up again. Tried formatting them with fastboot and didn't work. Tried installing the latest 7.0 factory image for the hell of it, nadda. Relocked the bootloader successfully. Giving up. Filed an claim online with my credit card company (most do a +1 year extended warranty), we'll see how that goes, if I get lucky they'll approve the claim and let me keep the phone. May pick up a used 5x or something.

I would stay away from the 5X as well..lol They are going through the same thing the 6P is going through. It's all over Reddit and XDA as well. I'm currently using the 6P but I'm waiting on the One Plus 3T to arrive. I have a few other devices to play with but I'm still using the 6P waiting for the 7.1.1 update to drop in a few days to see how that goes.

Oh what the **** . That sucks. My wife owns a 6P and my son has a 5x. So our house is a ticking time bomb of failure. Maybe I'll buy a Note 7 and finish the job. I have my old Nexus One and Tmobile G1, both still power on last time I checked. I've gotten rid of all other past cell phones we've had unfortunately. Used to have so much trust in the Nexus lineup

Lmao.. Yeah I would stay away. Also you have to throw in the fact that the devices only have support until at least Sept. of 2017, then unless you're flashing custom roms your basically stuck.

Yeah I mean I've always liked the Nexus devices because they always seem to have a good strong developer/modding community. I don't know the definition of a stock - anything. I recently converted my wife & son over to Nexus from Samsung's because I got frustrated with how they now lock down their phones. I have no doubt the 6P/5x (if they survive that long lol) will still be one of primary devices in this community to receive new OS/etc (cyanogenmod/whatever) well past the September EOL. Just look at the older Nexus phones still some of the first to receive the CM14.1 builds.

Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"

Note 4 wont turn on, "cannot boot normal" and "downlaoding target, dont turn off"
Its a Note 4 SM-N910F, Android 6.0.1, BB N910FXXU1DPE2, kernel 3.10.40-7733605 [email protected] #1
i feel I have tried everything... History:
Phone has been working fine for a year, upgraded to 6.0.1 no problems about 2 or 3 months ago. no new apps installed. Last week it started getting very laggy, keyboard strokes took for ever to register. I thought, ok, time to to a factory reset to blow out any old cobwebs. Did it via the menu. However the phone froze midway thought. I left it for an hour and then pulled out the battery. I popped it back in and it performed the reset without me having to press anything. Cool, thats good I thought.
Now I was going to change the battery, so I powered off as normal and put my other 2 week old original samsung battery in, and it would not power on. After a few reinsertions it powered back on. I though i have to do another reset. So I tried, and it would not reset. It just died. I cant restart the phone, it dies. If I shut it down normally. it wont turn on back on, I have to take out and reinsert the battery multiple times, holding down the powerbutton between to discharge. this can take up to 10 tries now. Sometimes it will go th the unable to bot in normal mode and "downloading , do not turn of target, but it will stay there for ever, more than an hour.
Every 15-20 tries it would turn on, let me get in via pin, only to start freezing up within a min, and then die again. Somewhere I read that a guy hada similar problem, and he used wakelock and that worked, on level 4. I managed to download that and used it, and hey presto, it works!
Now I had to power down the phone for a reason, and it took me about 30 min of battery and powerbuttonholding before it managed to boot up, and I was quick enough to start wakelock on level 4.
It wont boot in to safe mode, it wont boot in to recovery mode, it wont boot in to the factory reset mode. Its the same with either battery, and different cables.
Any ideas what i can do here, or what could be wrong? I havent gotten it wet or banged it.

I am having the same exact issue on a N910A. Phone was functioning correctly and in December it started getting really laggy. Performed various resets, purchased new battery. Still laggy. Up until two weeks ago the phone was slow but now it will not power on . The phone will not charge as well.

Mine did same, 6 months old, not rooted stock firmware. Locked up yesterday, couldn't do anything. Pulled battery and restarted. Samsung logo comes on screen goes black for android boot then it hangs with blue led flashing. Nothing I do gets it past that point. Tried safe boot but it doesn't fully launch with correct button combo and volume up. In the end I re-installed firmware using Keis. All went well, everything as per youtube tutorial. Except one thing, at end of download phone didn't re-start. Still can't get it to boot, any ideas?
Edit: Lock up didn't coincide with any new apps being loaded or updates of existing. Only change was a week ago which was an automatic update of the stock firmware (Lollipop)

are you still under warranty? i sent mine to a samsung center, the guy recognized the problem as the motherboard, said I wasnt the first. That was 3 weeks ago, they are STILL waiting for the parts. They say the Samsung factory are way behind with repair parts, etc etc. I am hoping it will go under warranty. Ill update when I know!

I've been having the same problem that started yesterday morning. I've tried a few different solutions but nothings worked, I get the feeling that my phone is dead and I'm not in warranty either. I'm going to approach Samsung but my guess is they will want more than the phone is worth to repair it. I've read about so many people having the same issues, its horrendous engineering on Samsungs part considering how much their phones cost to start with

Your guess is probably correct and I totally agree with you. I seriously think manufacturers do not want their devices to be problem free for more than two years. Probably why they have stopped making phones with batteries that simply pop out.

Definitely...surely it couldn't have been that hard to make a device with a battery that was still removable on the newer phones. It's frightening how many forum posts I've found with people having their phones just brick out of nowhere (and that's just the note 4). I've given up trying to fix mine, I've tried every method I could find and nothings worked. I can only assume that this problem is simply the motherboard of the phone not working anymore. I'm not even sure what phone to buy now but it certainly won't be a Samsung.

If you do not care about the camera thera are a lot of rather affordable options which can be tossed in the bin when they start malfunctioning and if their warranty has run out. If you care about the camera being as good as the Note 4's than the range of phones you can buy is quite limited.

If you are able to boot it into Download Mode then you should Download Stock Rom file for Galaxy Note 4 from Sammobile and Flash it through Odin..
Everything will be OK... ?

Unfortunately, SAMMOBILE does not have the SM-N910A firmware.

I think the camera on the note 4 is absolutley terrible. I might even go so far as to say the pictures are unusable. the applied noise reduction renders everything splotchy, colors are off and its not sharp at all. and Im not talking dark conditions here.
Anyway, my phone was repaired under warranty and is back to working as it should. It was indeed the motherboard, so if you have the same troubles I had, those are your best bets.

I don't think replacement via warranty will be available. I will attempt to power into download mode and verify if I can get it back up and running. If not, a good ole paperweight.

Sounds like the problems I have: with my first N910F: started with lagging apps / freezing, then random reboots now and then, eventually giving error messages when booting. Finally, now it will only start after the battery has been out for at least 30 minutes, but hangs on error message. When pulling battery out and putting back in it, wont give a single sign of life. Since I was just out of warranty it has been lying around, and I bought a second hand N910F for replacement, sadly its starting to give the same errors too and is just out of warranty too (its currently still working, but with freezes / reboots / and already a event with boot error).
I read It could be memory chips or some power chip on the motherboard, appears to be a common problem. So.... Last month I bought a new motherboard on ebay (chinese delivery, 80€). Received it last week and put it back in; phone is back to life. (putting it in is a very simple task, with iFixit teardown / guide)
Anyway, I love the Note 4 for performance / size / looks, and have been Samsung fan for a while, but this recent breakdowns and information that it is fairly common, has diminished being a fan fairly quickly and I guess the Note 4 will be the last Samsung device for a while after this new motherboard breaks down as well

Download the app "Wake Lock" and run the Partial Wake Lock option. Apparently the updated software impacts the CPU. For the restarting issue, put it in the freezer for a couple minutes. You may have to take the battery out once, but it has worked for me every time.

This looks very much like the issue reported here:
https://forum.xda-developers.com/no...-error-fix-t3434335/post72944466#post72944466
There are temporary fixes (wakelock), but ultimately this is a harware issue, and the fix is a new motherboard.
I think that underlying it is a problem with heat affecting the eMMC chip or its connection to the motherboard.

Hey can u pls get me the stock firmware for n910gddu1dpb4

You might find this interesting. Since I couldn't get mine to power up at all, I called Samsung tech and they quoted me $75 to fix it and they would pay for shipping. I figured it was better then getting another phone off Swappa. 2-3 weeks later i get an email that they are repairing it under warranty at no cost to me. I got a refurbished phone since i know my IEMI number was different. they didn't explain why. Anyway, I got lucky i guess.

S7 Edge SM-G935FD always Auto Restarting[urgent help needed]

In big problem.
My S7 edge is now automatically restating in every 10seconds.Practical I cant use it. I booted in same mode still restarting. I flashed stock Nougat and marshmallow stock ROMs still its restarting. Even in recovery screen(TWRP or Default) its getting stuck and restarting.
Only in Download mode it is not restating.
Please advice any ideas, since I am already on void warranty my $500+ phone is simply got useless.
Thanks in Advance

Maybe your power button is jammed?

When i checked, Power button is pressing and releasing. Power button is functioning actually, I can enter to Recovery, Download Mod and I can lock screen using power button. Or any other method to verified power button?

My S7 Edge did the same thing I reset it to factory settings empyrion I went in and did safe mode I tried resetting it and not installing any applications it seems that my ROM had gotten corrupted or something for no reason there was definitely a hardware problem. Never could figure out what it was I had insurance with Verizon and because I had cracked the screen barely three months prior before the problem began they stuck me with the $200 deductible to get it replaced. if you got insurance you will probably have to send it in but what mine was doing was it started just lagging then it just got to wear it wouldn't do anything it would freeze up and just reset and it would continually do that even when no programs installed except the factory setting and it would reset until the battery died I don't know that's exactly what you're experiencing but mine was in a constant Loop of reset it didn't get water damaged or anything the only thing I can figure is it had the 7.0 nougat update when it began doing this hope that helps you out sorry for the run on I'm talk texting I'm with the S8 now I haven't had any problems I'm just wondering if they've actually supported that I hadn't heard any other people having the same problems but mine surely did right after I got the update Android 7.0 on Verizon good luck bud

YES!!!..........Its exactly what you described. It started in the beginning like get slow>freeze with in 1 min>restart......But now after installing stock ROM back, its now directly restarting like a loop....Only difference we could use/see mobile for 10-20sec.....with in that time, it will restart again.
Unfortunately I dont have insurance.
If its hardware problem, samsung will rectify with accepting payment??

My S7 Edge did the same thing recently....no fix but to send for replacement. I reset it to factory settings. I went in and did safe mode. I tried resetting it and not installing any google apps. Seems that my ROM had gotten corrupted or something for no reason there was definitely a hardware problem or corrupted data in the OS or ROM. Never could figure out what it was. I had insurance with Asurion and Verizon but because I had barely cracked the outer screen 3 months prior (digitizer and oled where fine....was just outter guarilla glass which people complain about due to having no tempered glass to fit it correctly. So i had gotten the skin type scratch protector and one 2 foot drop onto asphault not even 2 weeks after receiving the object...pebble cracked it on the edge. Three months the problem began with freezing amd resetting finally b4 giving up and making a claim. ASURION stuck me with the $200 deductible to get it replaced because they said the drop/crack caused the malfunction though it worked perfectly for the 3 months...even had full sensitivity at the cracked area. If you got insurance, i imagine you will have to replace it. I did ad i saw no other choice and it ticked me off them sticking me with the deductible of full 200. Leave the cracked screen on hell. Just fix what they didnt fix when they got it to refurbish it initially. Have gotten at least 5 poorly refurbed phones that didnt last a year that was passed off as GOOD AD NEW. Mine started lagging then it just got to were it wouldn't do anything but cycle reboots. It would freeze up and just reset and it would continually do that even with no google or verizon account setup or apps. Only installed the factory settings which included the preinstalled bloatware. Phone would boot, then reset, boot and would reset again...continuous loop until the battery would die.
I don't know if that's exactly what you're experiencing but mine was in a constant Loop of reset. T here was no water damaged or anything other than a drop months earlier, an update, and i had recently moved some apps to the ext Sd card (which that should have been resolved at factory reset) cause i removed the micro sd card incase it was conflicting in someway from priorly having apps installed onto it.. the only thing I can figure is it had the 7.0 nougat update when it began doing this. Hope that helps you out. Sorry for the run-on sentences. I tried clearing up my grammar and punctuation...at least look a bit edumacated.? I had been talk texting.
Currently, I'm with the S8 now. I haven't had any problems so far. Dont like the default samsung voice input that it resets to constantly. But i am sure the S8 has more support for the new OS THAN DID s7. Phone companies are notorious to slack on support for models even 1 year old. Minimal support at best. You might get 2 Android OS updates. Not likely though. Pushing the new big thing each year and forget about the loyal customers that have chosen to spend out money with said co. rather than their rival. After the N7 hand grenades. Time that Samsung start supporting their phones updates a bit better. I'm really of the opinion that sufficient testing and support wasnt given towards the s7 the 7.0 OS. New OS updates Always buggie when first released. I hadn't heard any other people having the same problems as we did but i havent looked. Verizon claims no issues from the update. I question all retailers truthfulness on such issues. It a business and i see hoe much they mark up their retail products. 5 time the cost of internet prices many times.
Do report back pleas e. Sorry so winded....wanted to give all my thoughts and details of my exact experience. Hope you can fix it cheaper than i did. The s8 is sure to have more samsung support for a longer time. Nag them if you are settling with insurance. They can give you a new phone vs. Refurbed if they want to make u satisfied.
Good luck brother. Many blessings.

6P completely dead 2 days after Android O

Good morning all,
my 6p looks completely dead. I've installed the latest Android O factory image from the Google Developer site, flashed it and was running withot issues until today.
I was about to write a comment on Facebook, and then the phone freezed. After seeing how the phone was not recoverying, I tried a hard reset by long-pressing the power and both the volume keys. Then, the phone got a black screen, didn't vibrate, and now looks totally dead.
It's not charging or responding in any way, no matter how I press it. I'm quite confident the phone was over 50% when this issue occurred.
I don't really know what coul've caused this, but on my side, the preview was flashed cleanly with a complete factory reset, and I've only restored media files, without rooting.
Any ideas as to what should I do?

Do you get anything showing up on a computer when you plug it in?

Hi jmaclean, nothing, not even in Windows Device Manager...

I thought the Galaxy Nexus was a disaster but it appears that the 6P isn't far behind. Just bought a 6P (thankfully, a mint refurb) and am wondering if I made a bad mistake?

Yes a bad choice I would say - as an owner of a Nexus 6P device currently awaiting repair (thank god I'm in warranty) - I can tell you this device is plagued with issues that only become apparent as soon as your warranty is approaching expiry.
I love the phone, the design and build quality aesthetically speaking but would never be buying from Huawei again. The device is plagued with poor design that people believe leads to the CPU failing for some odd reason causing the dreaded bootloop issue.
My phone died literally in front of me and never worked again. I've contacted Huawei to get some clarification if this is an inherent fault as thousands are complaining about it and they just plain deny it and maintain if the warranty expires your out of luck. Apparently fixing the bootloop requires a motherboard change which in itself costs over $200 apparently. May as well get another phone for that as even the replacement component will eventually fail!

Sounds like a power issue. Maybe there's an open at the power switch or bad battery connector or battery. It most likely is nothing to do with Android oh it's just a coincidence. If you would have not even flashed Android O it would have still done this

seems like you will need to open up your nexus and unplug the battery, and then put everything together and try

I have owned this 6p for over 18+ months now. Never had any bootloop issues since day 1. A week ago i loaded factory image of Android O to this phone everything was working fine with great battery life.
I do not know if this is a coincidence with OP but i was also on facebook (chrome webapp) when during freshing of the page, the phone rebooted and since then it is stuck in bootloop.
I have connected to PC and reloaded the oreo stock image again and it completes successfully but again goes into bootloop. Any idea what should i do??

Follow the bootloop fix guide. I believe it's in the general or q and a section. It shuts down the big cpu cores but will get your phone going again. It worked for me. I was able to boot up and get some files off that hadn't been backed up yet. I was also able to use my phone until my RMA arrived.

Yes I was able to apply that and got it to work. Thanks

Nexus 6P Random Reboots after battery change

About a year ago the battery started failing. I finally got it replaced 3 months ago. The new battery ended up being faulty (wouldn't hold charge) and I got it replaced a week later. This is when the phone started acting up. Random reboots when opening certain apps (camera, instagram stories, youtube). So I got the battery replaced again (for free). The issue went away for a week or so but it started acting up again. A week back the finger sensor stop working (maybe the connector got loose).
I'm thinking of sending the phone in to another repair place to check it up but I've got a feeling the phone is just not fixable. The Nexus was never officially released here (UAE) so there is no official support from the manufacturer.
Is it possible that the repair shop messed something up to cause the random boots? Either that or the phone is just dying. The repair place has refused to replace the battery again stating it's not a battery problem (it cost me $80 to get it replaced in the first place).
I've already reset the phone and that didn't make the problem go away.
Any possible solutions would be great cause I'm close to considering a replacement (OnePlus 6 maybe since Pixel is super expensive) even though I don't have the budget for it.
The phone isn't rooted and is running stock. I've only got 38 active apps so I run it quite minimal.
Android 8.1.0
Kernel 3.10.73-g309d642
Build OPM7.181205.001
Thank you.
EDIT: I'm open to the idea of rooting if it fixes the issues.

This sounds for me like the issue with BLOD - but partly. There is a case where the 4 big CPUs dont work any more like they should but the phone do not bootloop at the boot time but at random situations later.
This would probably help you much time going from shop to shop if you could test it out on yourself:
1. Flash TWRP 4-cores version recovery (unlock bootloader before that to work). But maybe also the regular version with all 8 core enabled could work. https://basketbuild.com/devs/osm0sis/osmods
2. Then use in twrp this zip file to set your android os from 8 to 4 cpu cores(from the same link i posted above): N5X-6P_BLOD_Workaround_Injector_Addon-AK2-signed.zip
(full thread about that: https://forum.xda-developers.com/nexus-6p/general/bootloop-death-blod-workaround-zip-t3819515 )
If your reboots under load (your phone turns on the Snapdragon 810 BIG-cores to load the app) are then gone, then you know that the issue is on your big cores.
