I hadn't heard about heat actually fixing anything before this. Just heard about it being used to put the phone into limp mode for people with locked bootloaders. The 4 core images weren't working for me anyway, so I don't see how they would be relevant later on. I backed up everything I needed, so we'll see.

Just booting the phone into the bootloader and used the fastboot utility to flash the images. You can get them straight from the Google site.
[Nexus 6P General] superviked:
The heat thingy got me some animation on my phone. Before it never went past the Google logo but now I did everything exactly the way you said you did. How long did it take to boot to the OS though? Seems like I'm stuck on the animation.
[Nexus 6P General] mnetwork:
Took at least 15 min to boot up. If the logo is moving just let it do it's thing (while on a charger).
[Nexus 6P General] superviked:
Okay so it's been more than an hour and can't get past the boot animation. I can access TWRP though but it's asking me for a password. Any idea how I can change this? I haven't set any password.

[Update] Okay so after multiple tries, I was able to boot to TWRP, the stock rom didn't boot up so I flashed PureNexus 7/25 as per the first page via TWRP after randomly trying to mount storage and OTG, it could access my internal memory :rolleyes: and flashed EX kernel_4cores and after a merry 45 minutes my phone booted up and all is fine...for now.

PS: What a randomly annoying problem to have.

Thank you @ mnetwork.

Thanks ma man! i'e just upgraded to 8.1.0 with the 4core its running smoothly i appreciate your help bro! :good:
[Nexus 6P General] zameer hassan:
Hey..after flashing 4cores patched boot.img,my Nexus 6p running fine.

But,my question is for how long these 4 working small cores gonna last???

Is it also going to suffer bootloop after sometime like major 4cores stopped working???

Please,let me know.so,that I can prepare for the worst.
[Nexus 6P General] Trafalgarlaw69:
tbh, i dont have any idea at all, it may bootloop it may not depends on the usage of your phone, a guy i knew he's been addicted to it he went to toilette came back and found out that his phone has stopped completely (bootloop) so i bought it, here i am using it with the 4core running smoothly thanks goes to XDA developers.:fingers-crossed:

Oreo 8.1?

Forgive me for being a little dumb about this whole process but this is my first foray into non-stock stuff on Android. I have one of the Nexus 6p phones that landed in bootloop land a few weeks ago. I used this thread to get my phone working again and, thank you very much, it's been working quite well. Today I see that Android 8.1 is out and I'm curious about the upgrade and what it might do on my patched phone. Is it OK for me to go ahead and update my phone OTA to 8.1 or will this overwrite the patched stuff and leave me with a bootlooping brick again?
[Nexus 6P General] SlimSnoopOS:
The OTA would fail. Even if it installed, you would bootloop again. Google firmware enables all normal functions including all 8 cores.

Follow the thread below:

Could any body describe what will be the symptoms of bootloop. I mean symptoms if bootloop is going to come.

For example : Would it reboot once per day before went to fully bootloop
[Nexus 6P General] Einwod:
There IS NO POSSIBLE WAY TO TELL WHEN A BOOTLOOP WILL START. It JUST DOES. From ONE MINUTE TO THE NEXT. I WAS USING MY PHONE AND IT JUST RESTARTED BY ITSELF. That WAS IT, I WAS IN THE BOOTLOOP. I HAD TO WAIT UNTIL I GOT HOME AND ACCESS TO MY COMPUTER BEFORE I COULD REMEDY THE PROBLEM. All worked well for 3 weeks then the device just upped and died one night when I was using it. Battery was 80%. It just died. The only thing it would do was make the ding when connected to the computer by USB cable. It would not boot at all. Only the battery symbol showed when connected to computer and not when connected to mains charger. The device is back with the shop I bought it from as it is still under European 2 year warranty.
[Nexus 6P General] alwynjoshy:
Thanks for the reply, i am planning to buy non warrenty Nexus 6p so without warrenty purchase would be a mistake i am going to do? What is your opinion.?

Is this issue would come to all Nexus 6p or its just come to random nexus users only? :confused:
[Nexus 6P General] W@r10ck:
Plain & simple. Dont get nexus 6P. Save that $ for another phone.
[Nexus 6P General] Einwod:
The Nexus 6P is at the end of it's life cycle, unfortunately. As stated above, keep your money and go for a newer device. Personally I'm looking at the Umidigi 2 pro with a fantastic battery of 5100 μAh. It will be released very soon. Another I'm looking at is the Honor view 10.
[Nexus 6P General] T1Cybernetic:
I agree, Don't buy another one unless you have warranty! And even then I would not be buying another Nexus 5x /6p simply because it's a ticking time bomb!

I've just today ordered a LeEco Le Pro 3 as a change of phone ;) I could have gotten another nexus 6p easily for the same price and as it's been my favourite phone to date I would still use it now if it didn't boot loop on me :( But it's not worth the risk now.

The main thing i like stereo front firing double speaker of nexus 6p that is rare. Can't afford pixel 2 or i need to choose Zte axon 7
[Nexus 6P General] DodoGTA:
*mAh, not μAh
[Nexus 6P General] W@r10ck:
Then if you dont mind going through the hassle of experiencing the bootloop and accept the fact that when no fix would get back your device then go ahead buy it. Just make sure you have a warranty from the dealer or probably get an insurance.

Who can explain why the kernel 8core bootloop, and when the kernel 4core everything is loaded correctly ????
[Nexus 6P General] maximusmullivan:
Did you read the OP?
[Nexus 6P General] zameer hassan:
Octacore means not single 8cores but consist of two quad-core chip of 4 cores each.The 4cores which only kicks in when heavy gaming,playing HD video,graphic editing etc means works that put heavy loads on cpu.The other 4cores are for normal activities.

I have read somewhere that mobile phone with snapdragon 808 and snapdragon 810 chips have this bootloop issues.

So,when our phone starts the stock boot image, I think it uses all the 8cores.so,if 4 major core is stopped working suddenly then phone will hang and it will try to restart to fix this but unfortunately the 4major core gets damaged it keeps on bootlooping again and again.So,when we disable that core that causing issue and modified the boot.img it start but since the other 4core not working you will frequently feel performance lag at regular intervals.

Like our body has two kindey but if one kindey fails to work/function properly then the patient start feeling sick.So,after removing the infected kindey, patient can survive with only one kindey but his efficiency/power of doing work will reduce.He will get easily tired quickly compare to normal human being with two kidney.

I always upgraded Factory Images (with fastboot)... always with a unlocked oem and rooted....

Some days ago I upgraded to last FI 8.1 and rooted with SR5-SuperSU-v2.82-SR5-20171001224502.zip

I worked flawless... this morning I was driving (connected with my auto BT) and suddenly my N6P got stuck...

power button for some seconds for hard reboot....

and then bootloop...

Arrived home I tried to flash again last FI... and also the previous one... I tried also to erase userdata... always Bootloop...

Then I tried following steps:

- flash stock angler-opr6.170623.019 image

- flash Oreo4Cores boot.img file

- flash twrp3_1_1_4Cores.img file

tried to run recovery -> BLOD

tried to start normally -> BLOD

[Nexus 6P General] NoobInToto:
No, you cannot trust it to last long. I would say a month or two. The fix didn't work for many. If it works for you, it's good, but don't expect it to last. It depends on the core's health. The problem is actually fixable, but the repairmen are located only on china.

For me, battery life was pathetic. I sold the phone anyways. Have moved on to og pixel now.

[Nexus 6P General] Einwod:
The short answer is NO. My 6P worked for almost 1 month on the 4 core TWRP, boot.img and kernel. Then while doing something it went completely black and would not turn on again. It made the connection sound when attached to USB and the screen lit up with the battery symbol, but nothing else. The motherboard has been replaced under warranty for the second time and is on the way back to me from Germany as I type. Hopefully it will last me another year at least.

After my initial success flashing 4cores and a new android it went downhill very fast :( And now mine doesn't want to load anything past the fastboot menu which is really annoying because the fact that it loads to fastboot means something is working correctly so I keep trying with no luck :p

It's the optimist in me that keeps flashing files :D Or maybe this phone has finally driven me crazy :D

After flashing bootloader,radio,patched 4 cores boot,system and vendor step by step as mention in this thread,reboot.If after reboot it still bootloop,then go to factory option in bootloader mode and hit.It may then reboot to system.since,mine was having same issues even after flashing 4cores patched boot for next time but after trying factory option in bootloader mode it rebooted to system.

Please help.

1. My phone was stuck in bootloop. I found this Nexus Root Toolkit posted in youtube. I was able to boot to homescreen then I Enabled USB Debugging, OEM unlock. But after rebooting the device I was still stuck in bootloop

2. I thought locking and unlocking the bootloader should fix it but it got worse. Now I can't boot to recovery and I can't flash anything because the bootloader and OEM is tightly locked.

Please tell me there is still hope....
[Nexus 6P General] JStrauD:
I had the BLOD a couple months ago, used the 48B Patch on 7.1.2. and all was well.

BLOD came back today and simple reflash of the patched boot image temporarily fixed it. I made the mistake of deciding to try to upgrade to Oreo rather than just flashing EX kernel and moving on.

Since then, I have had BLOD no matter what I do. I can often access the recovery and fastboot menus but nothing past that. I have flashed 7.1.2, 8.0, 8.1 as separate files or updating then applying 4core fix. Same result every single time.

Any suggestions or the is the 6P toast?

[Nexus 6P General] squabbi:
Were you not on 8.1 before?

The main rule of thumb here is that the boot image (or at least the patched one) is responsible for making your phone work. You can be on any ROM, but the boot image must be patched to use 4 cores!
[Nexus 6P General] Humpie:
Hi, I'm on the latest 8.1 stock image and since last night my phone boot loops and doesn't get past the Google logo. I tried flashing several modified boot.img's as I suspect it's this problem, however I don't think there's an 8.1 version yet, is there? How can I perhaps modify the stock boot.img myself so it only uses 4 cores, or is this too difficult to do myself?

It's really bad as I cannot boot in recovery either, not even the modified 4-core twrp version

Edit: didn't see there was a patched version, trying that now

Edit2: Nope :( still looping

Nexus 6p bootloop

Hey. I applied your fix and the device is working now. Thanks a lot for the same.

I just wanted to know Presently i am on 7.1.2 and have applied the 4 core fix for 7.1.2 . Now My device shows that update to Android 8 is available . Should i download the OTA update and move to 8.0 while the 4 core fix is for 7.1.2. Waiting for ur advice.

Thanks in advance :):)
[Nexus 6P General] zameer hassan:
I think, it will again goes into bootloop. Better download factory image of android 8.1.0 from google site.Then,follow the same process as mentioned in this thread.Although, i have attached the procedure in pdf.Even after flashing patched 4 cores boot.img and other files in order mentioned in this thread,if it still bootloop.Then,choose "factory" in bootloader mode and hit.
[Nexus 6P General] squabbi:
Try staying on 8.0 if you can still get your phone to work on that version of Android. If you can change the motherboard, you can try that for sure, but it may eventually get the BLOD anyways. A replacement device would be more advisable.

---------- Post added at 08:55 AM ---------- Previous post was at 08:51 AM ----------

You will need to use a 4-core boot image that is for Oreo 8.1, not 7.1.2. As for updating, like the other member mentioned, use the factory image and download the appropriate boot image for 8.1. You can get it here: https://xdaforums.com/showpost.php?p=74774303&postcount=2

Can I just root like normal (i.e. simply flashing the newest magisk/SuperSU release zip in TWRP)?

What does it mean when the ROM/Stock boot animation goes for a while and then reboots into Recovery/TWRP?

[Nexus 6P General] squabbi:
Not as much, but it could be something in the /data partition or /cache partition that's making your phone boot back into the recovery. Does TWRP attempt to run an OpenRecoveryScript when it loads?

You could try formatting or wiping the internal storage.

---------- Post added at 10:37 PM ---------- Previous post was at 10:36 PM ----------

You should be able to just flash Magisk. Not sure what SuperSU does anymore but all if not most systemless soloutions will modify the /boot and /data partitions, leaving the /system partition untouched.

2. Tried booting to recovery and flashing OTA via "adb sideload" - nothing

3. Tried Freezin/Heating the device - nothing

4. Did "clear cache" "reset to factory default" - nothing

5. Stock recovery is installed

6. "fastboot flashing unlock" - not allowed

Phone will only show white Google logo on black screen and reboot again.

Just wanted to report I was able to flash Magisk 15.1 successfully!

I was previously running my 6P revived with the paranoid android 7.1.2 with the 4core fix posted in the first post. I also found a 4core 3.2.0.0 twrp recovery image that works perfectly.

Trying to upgrade to 8.x.x however was a bit trickier, I tried all sorts of combinations of boot images and ROMs, custom and stock, but what finally ended up working for me was the 8.1 factory image from downloaded from Google directly. I only flashed the vendor, radio, bootloader, and system images from that and then used the OPM1.171019.011 boot image that was "fixed" to only use 4-cores. So in short, stock 8.1 works and one can flash magisk 15.1 over it successfully.

As soon as I get home I'll upload the 8.1 OPM1.171019.011-4core boot img as well as the 3.2.0.0 twrp 4core recovery as I dont think I was able to find them linked in this thread specifically.
