Try letting it run (without overheating) until the battery runs down. My 6P worked great as long as the battery was under 10%, bootlooped again the second it went over 10%.

Of course, if you're in the process of flashing, you don't want the battery to charge through USB to jump past 10%....

Perhaps at 10% and under the hardware automatically goes into a power-saving mode?
[Nexus 6P General] burduli:
I already fixed my device, thank you.
[Nexus 6P General] fustyler:
were you able to boot past the boot animation and all the way into the OS when you did this?
[Nexus 6P General] outbackpaul:
No, after I did all that I had issues with TWRP not seeing my files. I just finished solving that by performing a factory reset and wiping user data and then DO NOT reboot anything.. I pushed the kernel, PureNexus, Gapps, Vendor Image, SuperSu to the phone in fastboot mode. First time I had done that. :)

After that TWRP saw the files I pushed and then was able to flash everything and get booted up.
[Nexus 6P General] tjchuot287:
Can you teach me how did you push all the files to the phone in fastboot mode?

Thank in advance!
[Nexus 6P General] di3cbl:
You can use ADB sideload in TWRP as well. Make sure that your phone is connected to your computer (you can enter "adb devices" in cmd and you should see your device id if you are connected properly. Then, go Advanced>ADB Sideload>Swipe the thing (I didn't check any of the checkboxes)>then enter "adb sideload <path to zip>.zip into cmd. It should start to install the zip like any other normal flash.
[Nexus 6P General] XCnathan32:
Try flashing TWRP, if you can flash TWRP and it will boot, then you can flash the EX zip

Some bad news on the 8 cores fix :(

In this thread: https://xdaforums.com/nexus-6p/help/dev-help-debugging-ramoops-bootlooping-t3640826/, I was fortunate enough to get the help of a smart dev, unfortunately, after trying the first fix, it seems that there is a fundamental hardware problem with the BIG cluster. However, we are still working on other possible solutions, so don't lose all hope yet.

If you want to follow the progress of the development, or help with the fix, check out the thread I linked up there ^
[Nexus 6P General] XCnathan32:
Interesting, keep us updated on how the phone works, and how the temps are.
[Nexus 6P General] bufosp:
i flashed the factory image of N2G48B, flashed the boot image from OP and twrp, still stuck in the bootloop. can't go into recovery as well even though twrp 4 cores is already flashed.

i guess i'm on the badluck side.
[Nexus 6P General] Skull2candy:
How to format userdata in twrp ..Please help
[Nexus 6P General] idkanything14:
Hey, thanks for trying to help us all. I really appreciate that. Unfortunately for me, I was able to follow the instructions but the boot loop is still happening. Is there away to go back to factory settings with the 8 cores? How can I remove the twrp file from my phone that I installed?
[Nexus 6P General] XCnathan32:
Flash the stock firmware
[Nexus 6P General] idkanything14:
Thank you. I am new to all this stuff. I found a link through Google. Hopefully it works.
[Nexus 6P General] fustyler:
I am able to boot into TWRP and flash all the necessary files, but the furthest I can go is the boot animation (4 dots jumping from purenexus). Unable to boot all the way into the OS.
[Nexus 6P General] burduli:
You don't need TWRP. Just boot into bootloader and execute "fastboot format userdata".
[Nexus 6P General] fustyler:
Managed to revive my Nexus 6P using Purenexus rom with the following.

From TWRP:

Obtain the files mentioned below and transfer to phone.

Format all partition except for internal storage.

1. Flash N2G48B_vendor.img into vendor partition

2. Flash N2G48B_4Cores.img into boot partition

3. Flash purenexus_angler-7.1.2-20170725-OFFICIAL.zip

4. Flash BeansGapps-Full-7.1.x-20170610.zip

5. Flash EX4_1_1_4Cores.zip (Elemental Kernel), step up the core speed one notch on first screen, leave the rest on default.

Reboot.

Waited about 10min on the animation screen (4 dot jumping), eventually phone completed booting
[Nexus 6P General] leroilion02:
hi m. XCnathan32

can you help me to see me how can i do this

step by step is dificult but i don t have other solution

thnx
[Nexus 6P General] rmorris003:
I just used the factory image and the flash all option, remove the -w in the batch file if you do not want to format.

use this guide too https://www.xda-developers.com/nexus-6p-bootloop-fix/
[Nexus 6P General] csunit37:
Same here. Tried everything and multiple times but no luck. :(
[Nexus 6P General] wpaholic:
i'm on the same boat, try all those things, even tried 1 core and no luck :crying:
[Nexus 6P General] XCnathan32:
Wait 30 minutes, if it still doesn't boot, hold power and volume down, when it reboots into bootloader, select recovery, and then connect your phone to your computer, and type "adb pull /sys/fs/pstore/console-ramoops" this will pull an error log, and you can send a pastebin link to me, so I can try to figure out what's wrong.
[Nexus 6P General] Vermanucci:
If you cant get into recovery you'd probably like to try the quick option of heating the touch sensor area of the phone while its boot looping before you give up. Try to get to recovery and keep heating it on and off until it goes in. I almost gave up on mine too after following all the steps that didn't work out at first.

[MENTION=494193]Ather[/MENTION] used a candle incense burner and had luck. Don't be discouraged because from the looks of things neither Google or Huawei cares about us, so we have to help each other to push on.
[Nexus 6P General] csunit37:
Tried the heating method too. The phone is still bootlooping. Still trying though. Maybe I'll get lucky.
[Nexus 6P General] Vermanucci:
What are you using? heat gun? hair dryer? other?
[Nexus 6P General] jspidey:
Thank you oh so much [MENTION=5288606]XCnathan32[/MENTION]! My N6P started to succumb to the battery issue (15% power of for a few days, then escalated to 20%, and 30% quickly), then the bootloop happened (do you think these are related? Maybe the sudden power issues is breaking something?). This all happened within a week's timespan. Your modified files helped revive the old gal after I replaced the battery.

For those having issues with forced encryption and getting the kernel or other files on the phone, here is what I did:

- Unlocked the bootloader

- Flashed the stock Android image

- Flashed the modified bootloader

- Flashed the modified TWRP

- Boot to recovery (TWRP) and connect the phone

Since Android had not loaded yet, nothing was encrypted and I was able to transfer the files just fine. Then I just installed the kernel via TWRP as the first post states.

The phone is not encrypted right now but I'm not too concerned. Plus, I think it being encrypted would probably hinder an already gimped phone.

I also found in my readings that TWRP *should* be able to unlock the encrypted partition, but it's flakey. Having a fingerprint set up seems to be a big no-no and TWRP will not be able to get in at all (in hindsight, this was my problem at first), if you use a pattern, supposedly you can enter in the "pattern" by pressing the dots to correspond to numbers on a phone keypad (never tried this myself). I'm guessing if you just use a straight up password it will work fine.

Good luck to all who need this info.
[Nexus 6P General] outbackpaul:
That's an interesting point. Right before mine died... the phone shutdown a couple of days before while at 35%. It had been 10-20%. I rarely let my phone go below 50%.
[Nexus 6P General] SGT:
Tried that as well. Cannot get into recovery.

Outside of barcodes, I get the Google and unlock logo and bootloop. Occasionally it just hangs on the logo. It's also not charging connected to my computer, which I thought was weird. If I leave it overnight I come back to a dead phone and flashing red led. Not sure if that has anything to do with it.

When I get home from work, I'll flash 7.2 again and then only flash TWRP. While I've tried this before, I'm sure, I've lost track.
[Nexus 6P General] Vermanucci:
It doesn't appear to charge from usb unless you have a little juice, go to bootloader and leave it to charge from there. If you allow it to boot loop while on usb it kills the battery just as quickly as not having it plugged to the usb

Otherwise use the oem wall charger to charge and while attempting any loop heat fix.
[Nexus 6P General] outbackpaul:
I'm not sure if this is related or not but when I try to restore my previous 6P backup from Google the setup wizard locks up. Only option is to power off the phone.

Has anyone else restored from their previous backup?

I'm on PureNexus 7/25 release.
[Nexus 6P General] marktsadkin:
Yes I did restore my lsat backup that was couple of minutes before the bootloop started. I'm on stock
[Nexus 6P General] SGT:
It actually died while sitting in the bootloader overnight...

I've also tried the heat tricks. Even let it loop while on a heating pad. ONE TIME it brought up the circles like it was going to try to boot. Then quit.

Still trying...
[Nexus 6P General] Vermanucci:
You probably need to go with more heat than a heating pad can provide
[Nexus 6P General] metallicant:
Same issue here. I had everything up and running with 7.1.2 stock but I wanted to try to run Pure Nexus and it's taking forever to boot. I'm at the bouncing balls at startup as well.
[Nexus 6P General] puddi:
I have random boot loops constantly and i think BLOD is coming soon. How can i speed it up ?. Because i have 3 months of warranty left so i can get a refund :)
[Nexus 6P General] XCnathan32:
Random bootloops is most likely enough to get a refund/replacement I would think. As for speeding it up, I don't know what you could do to speed it up.
[Nexus 6P General] GabeJ:
I can't afford a perfect 6P, but I'd be willing to purchase one that has had the bootloop fix. I know it'll be slower, but I'd rather have a slow 6P than no 6p. Message me, if you're interested.
[Nexus 6P General] SGT:
Put the phone on a heating pad and was finally able to do something. There didn't appear to be an os installed at all, after all that. After heating and restarting it came into failure mode finally.

While it was hot, I re-flashing again then loaded the 4cores and then twrp. It was SUPER Slow, but was finally able to load twrp. Super slow as in when I pressed a button, I could feel the vibration, but it would take at LEAST 30 to 60 seconds to respond. Sideloaded the ex Kernal while still heated up, rebooted... Still in bootloop. That whole process took about 4 hours to complete, but I didn't want to remove it from heat as I wanted to be sure to get everything loaded.

EX is now loaded. But the phone still won't boot. Iay try it all again tomorrow night, but for tonight I'm giving up.

Btw - on the heating pad on medium it read 46°C. On high I could get the phone to 49°C. (all according to twrp) This allowed me to leave it there and walk away.
[Nexus 6P General] lunchplease:
Thanks so much for this OP. Amazing stuff. I stuck mine under a pillow on my desk and got it oem unlocked, had to flash 7.1.2 then followed the rest of the instructions and voila!

Is there anything we can do to help test the 8 cores? If so happy to help as a tester as this isn't my daily driver any more so please let me know if I can help

Thanks once again
[Nexus 6P General] richychizy:
Has anyone rooted his device after completing the fix of the BLOD? I can't get pass a pattern lock in TWRP after flashing the recommended recovery. I don't remember setting it up but I have been entering the pattern lock on the device start up and it doesn't seem to unlock so I have no access to backup, install or explore internal storage in TWRP. SOMEONE HELP PLS. I wanna flash d EX kernel and SuperSU..
[Nexus 6P General] ladaluk:
great fix!! but cannot root

great fix!! thank you again!!

anyway this fix works with factory N2G48B rom only. cannot start up alternative (PureNexus, AICP) roms even root it (magisk). Flash boot img & EXkernel after rom flash too but no success.

Is there any working rooted rom?
[Nexus 6P General] fuadhdmini:
Tried both SuperSU and latest one Magisk 13.3
[Nexus 6P General] AgentBEATS:
For anyone who's flashed 4cores image but got stuck on google boot image this worked perfectly for me. Phone is finally functional after months in a drawer being a brick. Thank you!
[Nexus 6P General] Ather:
[MENTION=5288606]XCnathan32[/MENTION] can you share the steps to modify twrp for 4 cores? gonna try Android O :p
[Nexus 6P General] Ziyi Brandi:
After applying the N2G48B_4cores fix (my nexus 6p was previously reset to stock android 7.1.2) my phone no longer loops but instead gets stuck at the boot animation stage. I have done the fix twice and both times ended up getting stuck at the animation. Is there a way past this?
[Nexus 6P General] chandradithya:
I had the same issue, I flashed TWRP and wiped data and the phone booted fine after that. Im guessing its something to do with dalvik cache or something but a general data wipe fixed the issue for me.

Even after the data wipe it took 5-8 minutes for me probably thanks to the slow cores making the required cache files . Anything more than 15 minutes on the boot animation data wipe it.
[Nexus 6P General] fustyler:
I had the same issue. After flashing elemental kernel I was able to boot all the way. Look at my post above.
[Nexus 6P General] AddisG:
Thank you for this fix. Finally back and running.
[Nexus 6P General] Vermanucci:
Mine went over 54°C, I think as high as 58°C. I just focused the heating by the fingerprint sensor (as was suggested by [MENTION=2441494]Mediadriven[/MENTION]) and below the camera for fear of damaging the battery or other components

Pattern lock? I only got a password request to access encrypted userdata. Format userdata in twrp then push a none encrypted file to it and it should not ask for password again. After you get around that you should be able to root without any issue as i did. I'm still on the stock 7.1.2 rooted and running fine since Monday afternoon.

On stock 7.1.2 and rooted it with Nexus Root toolkit. Maybe you should get stuff fully working with the stock rom and then move on to custom roms afterwards.
[Nexus 6P General] metallicant:
Pure Nexus rom DOES work and so does Magisk 13.3 with this fix. Follow exactly what was posted a page or so before this and it will work. I could only get stock working until I read step by step what to do to get PN working and it does work. As others have already said, make sure you are flashing the vendor.img into the vendor partition. Apparently a lot of us who are having trouble is forgetting to do that....
[Nexus 6P General] zarriskem:
Since I brought back the phone to life, I have been experiencing horrible cell signal to no signal at all.

The same SIM works on other phones thought.

Anyone else have this problem?

I was also wondering, would changing the mother board make any difference?

I am cautious to replace it as I am worried that I would run into the same problems (Bootloops/ 4 cores not working well).

Any thoughts?
[Nexus 6P General] idkanything14:
Hey guys, if you bought your phone within 15 months ago, contact Huawei because they've extended the warranty by 3 months for the Nexus 6Ps dealing with the boot loop issue. They will ask for a proof of purchase and pictures of the phone of the sides, back, front, top, and bottom.
[Nexus 6P General] zarriskem:
Is this for the US only?
[Nexus 6P General] idkanything14:
I live in Canada. Give it a shot. My extended warranty expired earlier this month so, they're seeing what they can do for me. I told tech support that if I have to pay to fix this, I will not be doing that because I want to invest in another product that will bootloop after another year. I also said if I have to pay to fix it, I will never invest in another Huawei product.

Good luck!
[Nexus 6P General] phukao:
Hexacore

Did you try haxacore (Six Core 4+2)?

Any chance to success?

Cheer!
[Nexus 6P General] XCnathan32:
Right now, doesn't look like all 8 cores is gonna happen :/ I did try 5,6,7, and all 8 cores and it didn't work. So it's most likely a problem with the whole BIG cluster/component related to the big cluster
[Nexus 6P General] outbackpaul:
Yeah, I finally got all my apps reinstalled and was going to use it as my daily driver but even when connected to wifi it seems to be extremely slow.

I've still got a couple of tweaks to change as mentioned in the OP.
[Nexus 6P General] Dpax:
Device is locked. Cannot flash images

First of all, thanks a lot for your efforts towards fixing up this bootloop issue of NEXUS 6P

I have also tried to fix my nexus 6p, but i got stuck at step where i need to flash image

ERROR : Device is locked. Cannot flash images

Unable to flash anything....like recovery, custom ROM etc

Please help me in fixing this, i will be very thankful to you.
[Nexus 6P General] XCnathan32:
No not yet, sorry :/ I'll work on it some more tomorrow, as right now I'm too tired to do anything constructive without screwing it up.
[Nexus 6P General] mnhs1010:
No working for me

Both img not working for me.

i have flashed both twrp and boot img but did not boot-up.

help someone... just bootloop

just black google logo and your device software can't be checked this page comes, then keep loop
[Nexus 6P General] xringo:
holy **** thank you dude. I was going to sell this phone for cheap and just thought maybe give it one more time, came across this thread and flashed the first img file and it booted up. Still going to sell this phone

---------- Post added at 11:43 AM ---------- Previous post was at 11:32 AM ----------

Would you know that if I just flash a new factory image, which I assume would wipe your img file, would my device still turn on? Or will it only turn on with the big clustters turned off with your img file?

---------- Post added at 12:17 PM ---------- Previous post was at 11:43 AM ----------

Having a issue with twrp, its asking for a password to mount the device? How do I get rid of the whole password thing? I dont have any security setup on the phone or anything like that.
[Nexus 6P General] XCnathan32:
If you flash a factory image, you must flash my boot.img, because the factory image flashes the stock boot.img which has all 8 cores enabled. As for twrp, that's a new security feature, you can click cancel and still use twrp, or you can factory reset in twrp to get around it. EX kernel disables the password mount, so I would recommend flashing that.
[Nexus 6P General] XCnathan32:
What version of android did you have on the phone? And did you have a custom rom?
[Nexus 6P General] xian2380:
Will you keep update 4core elemental x kernel when next kernel release?
[Nexus 6P General] xringo:
I flashed this angler-n2g47w-factory-bd87661a and then your boot.img. My problem is with twrp, i cancel and dont use a password and then go to install and nothing of my internal storage will show, because it can't be mounted because the data is encrypted. Are you telling me to factory reset through twrp will fix this? I'm assuming its just go to wipe then swipe to factory reset?

Thanks for all the help and the modified boot.img file

[Nexus 6P General] DEVILOPS 007:
Thanks for actually finding the one and only proper bootloop bypass! It'd be awesome if one day someone could work out a way to enable all the cores again once past the bootloop but as it is it is an amazing fix.:D

My bootloader is locked... what can I do?
[Nexus 6P General] DawoodSahi:
I have this bootloop death scene with my old Nexus 5X, is there any solution for it? Please let me know if there is! Thank you.
[Nexus 6P General] DEVILOPS 007:
Cry... Are you not able to unlock it even with a bootloop? Is bootloader accessible and is USB debugging and oem unlocking enabled? If not then I don't know if you can do anything to fix it.
[Nexus 6P General] XCnathan32:
Yeah, I'm trying to fix that now, I've pinned the problem down to something about VLL failing to get a lock on the BIG cores, I need help from people who know more about that, so we can figure out a fix.
[Nexus 6P General] burduli:
Yeah that's exactly the problem, OEM unlocking was disabled before my phone bricked.
[Nexus 6P General] DEVILOPS 007:
I'm sure you could follow the guide he explained with the edits with your boot image. If you post it here I or the op could have a go.

---------- Post added at 06:26 PM ---------- Previous post was at 06:23 PM ----------

Well... Sorry. There are other methods to boot such as heating the back of your phone to trigger the cores and other methods. You can find many many different threads which might have an answer for you.
[Nexus 6P General] XCnathan32:
Sure will!

Yep

Dang... maybe you could try to replace the boot.img in flash-all.bat and then use flash-all.bat? Not sure if your bootloader needs to be unlocked to use flash-all.bat though.

I'll make a boot.img for the Nexus 5X and send you a PM so you can test it, if you're willing too.
[Nexus 6P General] burduli:
You mean flash-all.bat from factory image?
[Nexus 6P General] XCnathan32:
Yes, but replace the stock boot.img with the modified one in the zip file.
[Nexus 6P General] Einwod:
Stop posting the entire first post.
[Nexus 6P General] XCnathan32:
Your device is bootloader locked, so unless you can unlock it, you can't flash anything :/ You can keep trying to get the phone to boot, and if it boots, go to settings, scroll down, and then go to "developer options", and then enable OEM unlocking. If you don't see developer options, click "about info" in settings, and click on "build number" 7 times, this will enable developer options
[Nexus 6P General] Mediadriven:
PSA: Huawei has now extended the warranty on the 6p by 3 months. Contact them ASAP. They want the following:

Imei

6 pictures of the phone, front, back, both sides, top and bottom

Proof of purchase, this one gave me problems since I paid cash for the phone and the receipt is missing but after several calls I managed to get them to waive that requirement. Don't take no for an answer and keep asking them to escalate.

Get on the phone with huawei immediately and good luck.

Oh an btw, they will ask if you did your own troubleshooting, deny it. Reflash stock factory image and re-lock your bootloader before sending it back.
[Nexus 6P General] Epiphany2000:
No luck with my 6P

After spending several hours trying to resurrect my 6P, I've pretty much thrown in the towel. I restored stock 7.12 & flashed the modified boot and TWRP files innumerable times. After each attempt, the phone still bootloops when trying to boot OS as well as TWRP.

The bootloop started late last night. With this new fix recently announced, I thought I'd be OK, but no such luck... :crying:

If anyone comes up with a modified solution, I'll be happy to give it a shot. In the meantime, I slipped my SIM into a backup phone (LG Optimus L90). I plan to wait until a new billing cycle starts on my credit card, then shell out the bucks for a new phone. I don't like the idea of buying another Google phone after this debacle, but I don't care for iOS, or carrier/manufacturer bloatware. Perhaps a reluctant purchase of a Pixel XL is in order? :confused:
[Nexus 6P General] Mediadriven:
Read my post above, you may qualify.
[Nexus 6P General] THERAJ12:
I just called them. I bought the phone from Best Buy less than a year ago my warranty expired last month and the bootloop issue just began. The Huawei rep said they wouldn't extend my warranty because it has never been serviced before by them ( or else it would qualify). Didn't make sense to me I'll keep trying them.
