For your build ya need Boot.img from stock 48B, 7.1.2 firmware

Please make sure ya read 1st post and Download and Install the proper File

Your on 7.12........NOT 8.00

The Oreo4Cores.img file is for android O ver 8.0

Boot.img from stock 6.17, 8.0 firmware: Download | Mirror. This Image is the from the first official release of Android O, and is modified to use 4 cores. It also disables forced encryption as a bonus. Thank you to [MENTION=2004880]xls654[/MENTION] for figuring out how to get Android O to work.

Boot.img from stock 48C, 7.1.2 firmware: Download | Mirror. This Image is modified to use only 4 cores, and is modified to utilize the 4 cores more effectively. I have had multiple people say that first boot takes a while after flashing this, so just wait about 20 minutes before you declare something is wrong with it.

appreciate your reply dacuban1473 but what i did was i was on android 7.1.2 from where i got the update to android o after downloading and installing it the phone crashed into the bootloop and after that i flashed the oreo4cores.img then the phone went into the boot animation and never fully booted up
[Nexus 6P General] darkriff:
How did you install this oreo update.

Remind that by using this method you can not go back tu update or use default google update system, you need to do the updates manually. Thats probably why you are stuck in bootloop.

You need to download the files to you pc and install them using fastboot and the method described posts above
[Nexus 6P General] t_m95:
oh okay then will try to do everything manually then thankyou darkriff for your assistance ??

Instructions

How to Flash Factory images manually..

http://www.androidauthority.com/install-android-oreo-758342/
[Nexus 6P General] S_M_E:
I tried to use Nexus Root Toolkit to dirty flash oreo and it wouldn't boot but instead of getting a bootloop it was worse; it would crash to the recovery. So I used NRT to put it back to 48c and flashed the 4core kernel and system but that only put it back into bootloop. Maybe I'll try the manual upgrade to oreo tomorrow but something tells me it won't work and the only way to get the phone working again will be to factory reset it and start over. Time will tell...
[Nexus 6P General] dacuban1473:
Did ya fastboot flash boot 6p48C.img file or a kernal.img file right after you installed the factory Android 7.12C using Flash-All.bat?

Make sure your on 3.68 bootloader and 3.81 Radio just in case.

Good Luck
[Nexus 6P General] trjv:
just wanted to stop by and say a thousand thanks to OP for this thread! I've been trippin on how to fix my phone and this did the trick beautifully.
[Nexus 6P General] jspidey:
IIRC, what Google has released so far are just factory system images - the OTA files are not available yet. You have to wipe when flashing the factory images.
[Nexus 6P General] MaKTaiL:
Ok, went back to 7.1.2 and it's booting again. Currently the modified boot image you posted doesn't work without having to wipe the device. I hope you can figure out what's wrong ;)
[Nexus 6P General] fuadhdmini:
I don't it's the boot image at fault as you posted earlier below:

"My device usually asks for my password before booting, but with the boot image he provided it never shows that while stuck at the animation. He said he disabled forced encryption, maybe that's what's preventing it from booting on my device. I'm not being asked for my password."

The password prompt upon booting means your phone was encrypted.

Your phone was encrypted and the boot image has forced disabled encryption. There's a clash there.

That's why you need to wipe your device for any changes to properly affect.
[Nexus 6P General] omes000:
Hi All,

I was looking for some advice. My 6P started randomly resetting last week (usually when switching apps or had multiple tabs open in chrome). However, it would always restart as normal, until it didn't and got stuck in bootloop.

I was able to get an RMA from Huawei (even though I purchased on the Play Store; this whole process is a mess), so my main issue is trying to backup the data on the phone. I have tried the blow dryer/heat gun method. I would place the phone directly over the heat gun (with a few inch gap) with the heat gun set to 150F (for 10 minutes), then 200F (for 10 minutes), then I tried 300F (for 3 to 5 minutes), however, no amount of heat would cause the phone to boot up again. I have also let the phone just sit in boot loop for hours on end, and still it doesn't restart normally.

Does anyone have any suggestions on how to get the data off the phone? I am able to load into the bootloader. I have tried booting into 'Recovery Mode', but it just bootloops again. I believe I do have USB debugging enabled, but I do not have an unlocked bootloader.

I appreciate any help on this.

Thanks!
[Nexus 6P General] MaKTaiL:
He has to make a version with Encryption On then because I'm not wiping my device just to install Oreo.
[Nexus 6P General] metallicant:
Which Bootloader and Radio version should I be on before I flash to O?

I have 03.68 Bootloader and 03.84 Radio.
[Nexus 6P General] dacuban1473:
When you download factory Android O it comes with 3.73 bootloader and 3.84 radio that u can flash before loading O.
[Nexus 6P General] S_M_E:
No, like I said, I used the Nexus Root Toolkit (NRT) using the -nowipe option so I didn't run the bat manually. I did flash the correct 4core 48c kernel. the BL and radio versions are correct.

I've used NRT without wiping in the past, I've been trying to save my data. If I don't have to wipe the data (userdata) I might try again.
[Nexus 6P General] metallicant:
Thanks...
[Nexus 6P General] dacuban1473:
Ya can't flash twrp recovery or anything without unlocking bootloader manually or with a root tool. All in one tool is a easy way to do so. And load twrp 4 cores. Once ya do that you can use TWRP to backup data.
[Nexus 6P General] S_M_E:
I tried a manual flash of 48c over NRT's -nowipe flash using section 11 of this: https://xdaforums.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928

and swapping the 4core-48c kernel but it still bootloops. I might try the same method with oreo but it looks like I'm not going to be able to save my userdata. :(
[Nexus 6P General] S_M_E:
OK, so this time I used Nexus Root Toolkit to flash 48b (without the 4 core kernel) and it booted. I wonder if the problem isn't the kernel but something like an app corrupted or otherwise bad in userdata.
[Nexus 6P General] daproject:
One question guys, my 6p is still under warranty, I'm planning to send it for replace, should I get it unrooted and lock the bootloader first?

My phone is working with this fix just fine but I want to give a try to get it replace while still can.

What do you think?
[Nexus 6P General] Bobbaloo:
Wipe, root, lock yes. Though not necessarily in that order. I'm not sure of the order lol. Even though I did it when I first got this phone last year
[Nexus 6P General] dnsh89:
[MENTION=5288606]XCnathan32[/MENTION] the latest EX kernel has been released.. waiting for your fix for both flash and EX kernel..:good:
[Nexus 6P General] vladtdr:
I can deal with the lag. But I can't deal with the low volume on my headphones?. Need that elementalx kernel asap.
[Nexus 6P General] fuadhdmini:

[Nexus 6P General] rchtk:
You could have a try with the recovery I posted in the thread mentioned in OP (under credits). At least on my device it worked while with official twrp it didn't (problem doesn't come from twrp app so it could be kernel or external libs). You would then need to pull your data. Or even do a twrp backup which you can restore later.
[Nexus 6P General] S_M_E:
I was able to get it working using Nexus Root Toolkit, flashing the 48b (with wipe) factory image *without* the 4core kernel. I'm starting to think something was corrupted in userdata. Currently I'm restoring apps with Titanium from the nandriod backup created after it started bootlooping.
[Nexus 6P General] Balthazard:
I have a question for everyone who got Oreo up and running.

Do you guys have root access? Preferably Magisk? And if that's so how did you do it?

Thanks in advance
[Nexus 6P General] fuadhdmini:
Rooted, yes. Magisk. Tried magisk 13.3 working and also magisk beta 13.6.

How? Normal flashing in TWRP.
[Nexus 6P General] metallicant:
Proof? My previous post showing PIP working after I applied custom patch for YouTube via Lucky Patcher[/QUOTE]

Is this the Lucky Patcher app from the play store??

Owh I downloaded Lucky Patcher from mobilism. Google mobilism apk
[Nexus 6P General] Balthazard:
Thank you!

As a side note. Talking about Lucky Patcher is strictly forbidden because of the not so legal uses it can have.

But thank you again! I'll be trying it tonight!
[Nexus 6P General] kewvention:
seems like i have the worst luck. i also have a locked bootloader, but tried a hair dryer and it didnt work. then i busted out the heat gun, kept it going for 10mins but still no luck. the google logo comes and goes very quickly though.

what i did prior was reflash to a stock image, but it never booted up cause it was already bootlooping. im guessing i should clear the cache via recovery and try the heatgun again.
[Nexus 6P General] iplexus4:
So, can i just flash boot.img on working O and get 4 core only mode? After first try phone stuck on android loading screen and i back to stock core, but i still want to disable big cluster...
[Nexus 6P General] W@r10ck:
OMG it worked! You saved my life & my phone lol. I just got my device from RMA for 4weeks and which they refuse to fix because of a small dent but was not really the main issue. Will this be just a temporary fix? if I do OTA to 48C i guess i still have to flash boot.img? so glad my phone is alive again. Thank you very much.
[Nexus 6P General] timo_capa:
Out of curiosity, what happens when you toggle the cores online again in, say, Kernel Adiutor? May help with a log (logcat / dmesg).

If the cmdline change blocks them from going online, see if you can force them off via a hotplug or something and then disable core control?

Or, alternatively, do it manually.

write /sys/devices/system/cpu/cpu4/online 1
[Nexus 6P General] Ather:
thank you for this, my 6p has been in my drawer for about 5 months now,although it won't let me flash it since i need to enable oem unlock from settings, im trying to boot it using the heat up method but to no avail, will keep trying... thanks again for the hope
[Nexus 6P General] burduli:
Can you report back with your result? I'm in the same situation, my bootloader is locked and I think I'm out of luck.
[Nexus 6P General] Ather:
well i tried heating it for around 5 minutes, nothing still reboots on the dammed Google logo, trying to put it on charge under the pillow now, will report back
[Nexus 6P General] vip57:
It is a good news for lg v10 users

Hope someone will make it work
[Nexus 6P General] Albert62:
Thanks OP. Had my N6P for months just in case Google decided to do something about it.

I flashed everything and it seems to be working good for now.

I might still leave it again on the drawer because I already purchased the OP3T, but it's good to know that is working again.
[Nexus 6P General] burduli:
I did the same. Device is still hot af but it's still bootlooping to the Google logo.
[Nexus 6P General] rchtk:
That's exactly what is being done in init.angler.rc (can't remember the exact filename). Which contains interesting lines (enabling 4 and 5 and disabling again). I did modify rather heavily this file and repacked initrd but that also didn't work for me. But there are a lot of things to try and might work for others so it's something to investigate.
[Nexus 6P General] chandradithya:
I screamed in joy after the phone went past the google logo to the boot animation, Thank you so much for this. You are a savior.

I was very depressed after my phone bootlooped a week after my warranty ended, Especially when i spent a bomb on replacing the display too. Glad to know i can still use the device for basic tasks and the camera.
[Nexus 6P General] RyomaEchizen:
Where i can do this? :confused:

When i flash ElementalX i only see "Select i/o scheduler". I'm using FIOS. That's ok?
[Nexus 6P General] XCnathan32:
I/o scheduler is for the eMMC chip. Download kernel auditor from the play store, and you can change the governor there, as long as you're rooted.
[Nexus 6P General] XCnathan32:
The LG v10 uses the same processor as the LG Nexus 5X, which I made a fix for. I can make a boot.img for the LG V10, and PM it to you so you can test it.
[Nexus 6P General] liquidgalaxy:
Thank you so much! You just revived my girlfriends BLOD N6P! It was a 14 month old subsidized phone that the telecom provider nor google would replace or warranty. Ended up getting them to buy out of 50% of the contract and provide a 'free' 2 year Pixel XL but this is a nice silver lining! Hopefully I can find a place to buy you a coffee or beer!
[Nexus 6P General] outbackpaul:
I'm so close... stuck at the skipping dots.
[Nexus 6P General] XCnathan32:
It can take a while to boot for the first time (20 to even 30 minutes), if it still hasn't booted after then, trying restoring the latest stock firmware for 7.1.2, and then re flashing, if it still doesn't work after that, try using EX kernel instead of the boot.img, or vice versa.
[Nexus 6P General] outbackpaul:
Yeah, I was just going to wait. I've got it on the charger.

It's so awesome that you did this.
[Nexus 6P General] Bubba_:
How long should it take to boot

How long should it take to boot once .img files are flashed I got to the boot animation and it just sits there it has been like that for an hour.
[Nexus 6P General] XCnathan32:
Hmm, try flashing the latest factory firmware for 7.1.2, and then reflashing the boot.img, if that doesn't work, then try EX kernel.
[Nexus 6P General] dadoc04:
I love this place!!!

Thanks OP
[Nexus 6P General] outbackpaul:
So I flashed the boot.img and the twrp and then did a sideload of the EX kernel. I just used the defaults in the Aroma Installer for the EX kernel. I didn't wipe Dalvik/Cache. You think not wiping had anything to do with it?

I had EX kernel installed before the phone died.

Wow saved my bacon! Got the boot loop issue about two weeks ago just before I went on holiday and was thinking my phone was finished. Just tried this this morning after having no phone for two weeks and after flashing 6p48c image on my stock Nexus 6p and its back from the dead.... Thank you soooo much :)
[Nexus 6P General] osamaasif786:
Man thanks a ton! You saved my phone! One more thing, are you working on making elementalx 5.03 work for 4 cores? Thanks! Keep up the good work!
[Nexus 6P General] XCnathan32:
Update: OP updated with 4 core EX kernel for Android O. For now, you will need to flash it over the already modified boot.img for it to work.
[Nexus 6P General] XCnathan32:
Yep, as long as you don't have a custom ROM, it should work.
[Nexus 6P General] titustitustan:
Hi, I must've done something wrong doing the Oreo4Cores because after doing everything, I'm not bootlooping but I'm booting into the bootloader every single time :)) It's like bootloop laughing at me. I've retried the reflashing process and still came back to it.

Please note where I might have overlooked anything:

1. Flashed O factory image (from dev preview) in fastboot;

2. Flashed the TWRP recovery img and Oreo4Cores boot img;

3. Went to TWRP, transferred 6pEX4_1_2.zip and installed the zip

3.1. All stock parameters chosen for the EXKernel installation; exited TWRP

PS. been reading this thread almost everyday since the day it was posted. this has been a very humbling 99-page thread.

---------- Post added at 03:42 PM ---------- Previous post was at 03:39 PM ----------

SORRY! I probably didn't catch the new EXKernel version when you put it out (could this be the reason?) Can I just install this v5 over the v4 or should I reflash everything?
[Nexus 6P General] SlimSnoopOS:
Use modified EX 5.03 from the OP.

Ex 4.12 is for Android 7.1.2 and won't boot on Android 8.0.
[Nexus 6P General] titustitustan:
ok don't mind my earlier post, it works now. :D
[Nexus 6P General] tuananhmap124:
sorry noob question here, why can't I flash the kernel files? it said error: cannot load name of the file. Thanks in advance!
[Nexus 6P General] SlimSnoopOS:
Could you provide more detail? TWRP or fastboot? Which partition are you flashing them to? Which file? If fastboot, have you updated your platform tools if flashing for Android 8.0?
[Nexus 6P General] tuananhmap124:
:) I think it's TWRP. i use command promt in the modified folder, exactly the same as in the instructions. I used the Elemental X kernel version 4.12 file. Thank you for your reply!
[Nexus 6P General] SlimSnoopOS:
After you flash TWRP, are you booting into TWRP to flash Ex 4.12? EX 4.12 is not meant to be flashed in fastboot.
[Nexus 6P General] tuananhmap124:
Wait a minute... I'm such a dumbass, i don't have access to TWRP so I was actually using fastboot :eek:

[Nexus 6P General] W@r10ck:
Hi guys just a quick two questions. 1.) why does twrp always asks for Mount Decrpyt data password everytime i boot into recovery. I can cancel it but what does it do when you put in a password. What is the password? 2.) i cant seem to flash supersu. It doesnt detect the zip file. why?

Thank you guys.

For those with locked OEMs

Hi - amazing thread and kudos to [MENTION=5288606]XCnathan[/MENTION] for doing for the community with Google and Huawei wouldn't - you're the best mate! I have a question (and I am going to read through the threads, but didn't find something specifically). Since this method needs fastboot, I cannot try this as my OEM Bootlock was not turned on. I cannot get back into Developer Options as the phone is only in bootloop, but I can, however, get into stock recovery and I can do adb sideload. Is there a variant of this image which I can load using adb sideload? I am not very android literate, so I apologise if this question doesn't make sense ...... but I imagine others would have similar situation? Would greatly appreciate any help.
[Nexus 6P General] darkriff:
did you try heating the phone app to get it to boot ?
[Nexus 6P General] chait:
Guys,

I have a query. Has Android O ensured that Bootloop issue is fixed? It is now a known issue for Google.
[Nexus 6P General] WonderAndro:
Hi - I did not. Do you mean with a hair dryer? I just found out about that trick after googling with your answer. Can give that a shot tomorrow and see if that does anything, thanks!
[Nexus 6P General] eclairsp:
Guys,

I am new to all this. I flashed the 48C img and my phone has now been booting up for around 40 minutes. How much longer will it take or did I do something wrong.

I am on August update of 7.1.2 and flashed the 6p48C.img
[Nexus 6P General] WonderAndro:
Also after re-reading the initial post, I think the adb sideload will only work with a Google signed package, and that is what [MENTION=5288606]XCnathan[/MENTION] has requested in his petition to Google. It might be useful if everyone who cares about this problem signs that, and also tweets / shares this to get more views. As we know, "even the smallest person can change the course of the future" :cool:

elemental for Oreo

Hi, came out the core elemental for Oreo. Can you modify it to work on 4 cores?

No, you need the modified files to fix a bootloop. Google will not acknowledge the issue.

That's awesome! I can't say thanks enough for all the support. Unfortunately, I doubt Google will ever address the issue, but hey, it was worth a shot.
[Nexus 6P General] metallicant:
All I did was flash the stock boot.img and then applied the 4 core o patch again and everything booted up and running fine with the stock kernal. I just read your response that I only needed to flash the 4 core O patch which is the stock kernal.
[Nexus 6P General] BRUTETERROR:
So I've been trying this fix ever since it was first posted. My device is unlocked, can boot into recovery and flash files just fine, but I have not yet been able to get it to boot. The bootanimation 'animates' for about 0.7 secs before turning off and starting again. Tried with different ROMs aswell. Thought Oreo might change things, but no such luck for me. Also applying heat doesn't work.

PS: Holy crap it actually started up as I was writing this, but instantly shut off again though. Keeping my fingers crossed.

Yes the bootloops are due to the SoC not being properly soldered so if you want to use the big cores again you'll have to get it re-soldered like a few guys with their 5Xs did in this thread: https://xdaforums.com/nexus-5x/general/4gb-ram-upgraded-nexus-5x-t3588743
