[Nexus 6P General] Lughnasadh:
I would suggest to make sure your platform tools are up-to-date (30.0.4 is the latest I think) and flash the last factory image (Dec. 2018) with the flash-all command instead of flashing partitions separately. If you have the BLOD it won't boot but then you can apply the fix from the link below, which is the latest and best method. The fix in this thread is outdated.

Thank you for your response Lughnasadh,

I originally started with flash_all as I didn't think it was core issue, and flash_all failed at the boot image writing phase.

[Nexus 6P General] Lughnasadh:
I think you can use fastboot to format the boot partition (fastboot format boot....I think). You can also get those errors from having outdated or bad platform tools. You can also try using a different cable.

But what concerns me is that you can't boot into TWRP after flashing the 4core TWRP. This usually means that there are other things going on and that likely your phone is dead. Here is a quote from the OP:

"If no 4core recovery boots for you then you definitely have more components than just the performance cores separated, sorry but your device is a brick."
[Nexus 6P General] badabing2003:
Thanks, I was afraid of that, I'm using the latest platform-tools

fastboot --version
fastboot version 30.0.4-6686687

and formatting boot doesn't work either

C:\angler-opm7.181205.001>fastboot format boot
fastboot: error: Formatting is not supported for file system with type ''.

I think I need to recreate the partitions, if there are any tools to do that, I might save this

but I don't think fastboot can do that.

Thanks

minimal_adb_fastboot_1.4.3_portable is old but it flashes boot.

the newest fastboot returns error about size 0x.

So using newest is not obligatory, but to explain why older or newest, some deeper understanding is needed;)
[Nexus 6P General] Apand019:
Hey man. Seeing all the positive post about this is great. I was trying this method and when I tried the "fastboot flashing unlock" it showed me "oem unlock is not allowed" error. Is there a fix for that?

Thanks.
[Nexus 6P General] Lughnasadh:
Go into developer options and see if you can toggle on OEM unlocking. If it is grayed out in the off position you probably have a Verizon model and won't be able to unlock you're bootloader. If you can toggle it on, then do that and also turn on USB debugging, then run the fastboot unlocking command again. Then go to the thread below and use that method as this method is outdated.

I tried it but it's still in bootloop.
[Nexus 6P General] metallicant:
Nope.
[Nexus 6P General] burduli:
So I just have to plug it in and wait for it to boot? But I tried that many times in the past 4 months.
[Nexus 6P General] Snow_ball:
You need to flash the boot.img or ex kernel through fastboot and then restart the phone - it should now boot up. This assumed you are already on 7.1.2. If that's not the case, you have to flash that, first.
[Nexus 6P General] burduli:
I know that. The problem is that I have locked bootloader, so I can't really flash anything.
[Nexus 6P General] Snow_ball:
I am sorry, I missed that. The idea is that heating the phone up sometimes seems to bring the faulty core(s) back for long enough to boot up so you can enable the OEM unlock. In that case yes, you just let your phone bootloop while heating it untill it starts.
[Nexus 6P General] metallicant:
Make sure the battery is below 10 percent.
[Nexus 6P General] burduli:
THAT WORKED! I completely drained the battery, let it boot up, but it shut off immediately. Then I plugged in the charger and let it boot again, it booted up, I finished setup wizard and then enabled Developer Options, then OEM unlocking and USB debugging! Thank you very much sir!

flashing n2g48b stock image

Do you have to have the stock image n2g48b for the 4 core boot image to work? I was on nuf26n (I'm currently trying to flash n2g48b) but none of the fixes were working... I'll update if it works.
[Nexus 6P General] PVTD:
GENIUS! Thank you!!!!

IT WORKS!!!

After months of trying to find a way to get the stone to work again, you have done it in a simple way and I am happy.

How I fixed it (for those who don't really know how to get it to work as it might sound complicated)

DL and install Nexus Root Toolkit v2.1.9 and follow the instructions on that page to set everything up.

Unlock bootloader (if nescessary)

Flash Stock + Unroot (this is to clean everything up and make sure the process goes well, leave Soft-Bricked/Bootloop selected)

Download Android 7.1.2 Factory Image (angler-n2g48b-factory-34c51cad.zip)

On the Nexus Root Toolkit select first Other/Browse... and second I downloaded a factory image myself..., leave the checkboxes unchecked. Then OK and find the factory zip you just downloaded.

Once it is installed, boot into Bootloader again, go to the main page of the Nexus Root Toolkit again and launch Advanced Utilities.

Select Launch CMD Prompt

Download the files from [MENTION=5288606]XCnathan32[/MENTION] (N2G48B_4Cores.img)(twrp3_1_1_4Cores.img) and (EX4_1_1_4Cores.zip make sure to select download on the top right arrow).

The first 2 files downloaded (N2G48B_4Cores.img and twrp3_1_1_4Cores.img) you have to move or copy them to C:\Program Files (x86)\WugFresh Development\Nexus Root Toolkit\data.

On the CMD (black windows that opened) paste: fastboot flash boot N2G48B_4Cores.img , then paste: fastboot flash recovery twrp3_1_1_4Cores.img . This will install the fix.

Now go into the recovery (Power + arrow up) and copy the third file into you phone's memory. (EX4_1_1_4Cores.zip)

On TWRP go to install, find the file you just copied (EX4_1_1_4Cores.zip) and install it. Press OK till you see the CPU boost options. The first one you will select 1632 MHz, all the other options you should leave as it is (just keep pressing next)

Reboot, you should have a working phone like I do :D

I only logged in to write this as XCnathan32 deserves more then a cookie!

After flashing the boot image, the phone booted into the google logo but got stuck there for more than an hour. After this I went back into TWRP and flashed Elemental kernel - it booted past the google logo screen, but is now stuck in the boot animation of purenexus (4 dots jumping). One step closer but still not all the way yet. Any suggestions from the gurus?
[Nexus 6P General] rmorris003:
Finally my Nexus 6P is alive again, it's been one month since battery died and it would not boot past Google logo.

I used 7.1.2 (N2G48B, Jul 2017) factory image.
[Nexus 6P General] burduli:
So I finally booted into recovery but TWRP asks me for decryption password. What can I do? I clicked cancel but then it doesn't show internal storage content. What can I do?

EDIT: I fixed it by formatting userdata.

Locked Bootloader

is there any solution if i haven't unlocked my bootloader(OEM unlocking not enabled before bootloop started) ???
[Nexus 6P General] Neontc:
Any advice for us that can't even boot the 4 core recovery?
[Nexus 6P General] Vermanucci:
You can format userdata but if it boots into android without any files it encrypts it again. I pushed files to it while in twrp before it got to android and it prevented it from encrypting itself.

For persons having issues after all the flashes, it may be necessary to heat the device (as i encountered the same issue). Allow the phone to boot loop while heating and it will either go into recovery or attempt to boot to android. When the boot animation appears you may continue heating the device for a few seconds after, around 10 to 15 worked for me. When it gets to android it may shut down because of the heat, try to get it into recovery if it does (if you have twrp) and let it sit and cool.
[Nexus 6P General] burduli:
Thanks for that. I was wondering why it encrypted data partition again.
[Nexus 6P General] marktsadkin:
First of all thank you for your fix! Saved my Nexus 6P, but unfortunatly I already deleted my data.

Secondly, How did you manage to install PureNexus ROM (Jun version- latest) on Jul update?

Why would it say there is no space left on the device even after formatting system and userdata? Is that a thing that heat would fix?
[Nexus 6P General] Vermanucci:
The heat was just a jump start for the processor I guess as no steps worked for me before heating the device.

I used Wugfresh Nexus Root Toolkit to flash the factory image, I am not sure what would cause that I/O error.

EDIT: Fixed it by copying files one by one.
[Nexus 6P General] Neontc:
If I flash the images manually, it'll go through just fine, so no big deal. So I got the factory firmware loaded, then I run 'fastboot flash boot N2G48B_4Cores.img' and 'fastboot flash recovery twrp3_1_1_4Cores.img'. rebooting into that recovery just sends me back into the loop. :crying:
[Nexus 6P General] Vermanucci:

I needed to recover pictures so couldn't do this fix at first. Hopefully this post can help people out in the similar situation as me(pictures were being backed up in 'high quality' not original quality). Thanks to [MENTION=5288606]XCnathan32[/MENTION], I realized we just needed to shut off the 4 cores to get this to work long enough transfer my files via usb. So what I did was open the phone to separate the motherboard from the heatsink/thermal paste. Then I used a hairdryer on the cpu until it started to boot up (took about 1-2 mins), once you see the 4 dots immediately stop the hairdryer. This was through trial and error, I think if the cpu got too hot, it just turned off. I was able to boot up to transfer all my files. For some strange reason though, the phone stayed on without rebooting/shutting off by itself. I tried turning it on this morning and it was working fine. I will report back to you guys as I keep testing it.

I have already reverted back to my good ole' nexus 6, so not using my 6p full time.

7/26 - Just wanted to give you guys an update. I've been using my phone with no issues for the past 2 days. I've purposely tried to get the phone back into bootloop. Turning the phone on/off. Trying to run cpu/gpu intensive apps, ran AnTuTu benchmark app. Was monitoring the temperature and I'm not sure what the normal temperature is but it was in between 29C - 53C. I'll keep updating this.
[Nexus 6P General] NOlSY B0Y:
Hey, is this possible on a n6p that did not previously have the bootloader unlocked before the bootloop? I have followed all the steps, but the device does not show up in CMD when "fastboot devices" is entered.

I think someone may have figured out how to fix this with all 8 cores enabled, I'm gonna do a bit more testing, but hang tight guys, the perfect solution might be coming very soon :D
[Nexus 6P General] burduli:
WHAT?!
[Nexus 6P General] Vermanucci:
My Kernel adiutor shows all 8 cores are being utilized; When I flashed ex kernel i overclocked the slower clusters by 1 step up from stock (1632MHz) and under clocked the fast cluster to a little above the slow cluster [no more than 100 MHz (1728MHz) if i remember correctly].
[Nexus 6P General] XCnathan32:
I tried that, and it didn't work for my device, I guess you're one of the lucky ones.
[Nexus 6P General] Vermanucci:
Remember i wasn't so lucky getting stuff to work with the straight flash on multiple devices at first. I think i got lucky with something in the heating process. I'm still monitoring it though and i'm gently pressuring the devices.

What was the result when you tried?
[Nexus 6P General] outbackpaul:
I'm pretty sure that means you don't have the correct drivers installed.
[Nexus 6P General] XCnathan32:
Same result, not booting due to VLL lock failure, I tried underclocking it all the way down to 384MHz, and even that didn't work. Hopefully the solution i'm working on now will work though :good:
[Nexus 6P General] Ather:
DUDE YOU'RE AWESOME!!!, so after countless hours wasted with a hair dryer i used a candle incense burner and voila it booted to setup wizard, skip, settings, oem unlock on, fastboot flash recovery, flash ex kernel zip and presto!! everything works! thank you very much again!
[Nexus 6P General] XCnathan32:
If you're on linux, you need to run "sudo fastboot" for any fastboot command. I think windows needs admin privileges too.

---------- Post added at 08:49 PM ---------- Previous post was at 08:46 PM ----------

I think this is what I need to do, how did you go about doing this? Just apply heat to the top of the device, and try and boot it up? Do I need it connected to power? And how do I skip the setup wizard?

Thanks in advance!!
[Nexus 6P General] burduli:
I tried heating trick but it didn't work. What worked is this: I drained my phone's battery completely. Then I powered it on. It boot up, but shut off in about 5-10 seconds because it was low on power. Then I connected charger and powered it on again. It looped a couple times but then it started booting. When it finally booted, I clicked on 'skip' on almost every step of the setup wizard. Then immediately enabled developer options, OEM unlocking and USB debugging.
[Nexus 6P General] martinfarrell11:
How did you? I tried a lot of things and it only says... "Google"
[Nexus 6P General] NOlSY B0Y:
Same here, mine is currently trying to boot up. It won't power on unless it's connected to power it seems, however a red light will blink in upper housing above the screen. From what I understand, the only way to perform the fix is to boot up the device somehow to unlock bootloader.

Any suggestions appreciated! And I'll share anything that works for others still stuck
[Nexus 6P General] martinfarrell11:
The red led is for low battery. For what I read someone let the phone drain all the battery and turned it on with the charger
[Nexus 6P General] NOlSY B0Y:
WOO so what seems to be a fluke, my Nexus booted up after I let it sit and loop for a while . It gave me enough time to enable bootloader so I don't have to worry about that now. So relieved!

But I still have the issue of nothing coming up when I insert "fastboot devices' CMD. Keep in mind I'm on windows, and I am using 'open CMD window here' with user level priveledge. Should I redownload all drivers, or is there a way to run the CMD in admin?

I would try the EX Kernal, but unsure how to do something other than IMG in fastboot, and not finding any documentation on a quick search.
