Nexus 6p Bootloop issue.

Yes I have been hit like many others. Although still in warranty they won't fix/replace it due to a cracked screen done over a year ago...long story but the short one is I been trying to fix it with the flashing the boot loader to reduce the number of cores - all found here: https://xdaforums.com/nexus-6p/general/guide-fix-nexus-6p-bootloop-death-blod-t3640279

What I'm hoping to that one of you clever sticks have either experience of this or are able to provide some support. I have managed to flash it once and it got all the way through to reinstalling all the software etc but then hung and then got stuck in the boot loop again.

Every other time I've tried it, either with slightly different versions of the same one I get a mixture of; boot loader is unlocked (which I then lock), my software has changed (Google then stops it loading) or more recently just the white Google symbol and nothing happens.

Im desperate to this working and any help would be gratefully received. All my thanks in advance.
[Nexus 6P General] el.quechon:
Guys would replacing the motherboard fix the issue.
[Nexus 6P General] dacuban1473:
Try manually erasing data and flashing stock nouget radio and bootloader then flashing nouget 7.12 back on phone. Use the boot.img for 7.12 from first page here and just put twrp on it. Then try Oreo again. Good luck.

Should be fast. Mine took under minute.

Yea i probably missed something when flashing .zip file, I will probably try updating through OTA and then root again. :)

Possible Bootloop Fix

Perhaps some of you or us actually have a corrupted EFS partition that is causing these infinite bootloops. It's not a super common occurrence and has only ever happened to me one other time over the years... and why most people might overlook it or not even know about it at all. For anyone who thinks this could be the case and is desperate for answers, do try number 9 on the thread found here: https://xdaforums.com/android/help/guide-revive-angler-bootloop-t3454938

9. If it still does not boot at this point, then you need to run these adb commands (while in TWRP) that [MENTION=4905158]bogomil4e[/MENTION] kindly reported to wipe the EFS partitions

adb shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst1 bs=16384

-and-

adb shell dd if=/dev/zero of=/dev/block/platform/soc.0/f9824900.sdhci/by-name/modemst2 bs=16384

Note: Before doing anything related to altering the system... It's always a good idea to back up the EFS partition in TWRP and keep one on hand at all times just in case something should ever go wrong now or sometime into the future. Making a nandroid in general for emergency backup purposes is always a good recovery idea, but you hopefully already knew that if you're here.

Running the two above commands via ADB in TWRP will clean up and restore your EFS partition and takes literally two seconds to execute. If your EFS really is corrupted you WILL ALWAYS be stuck in a forever bootloop until you fix it. Hope this helps someone get their device back in shape who might actually have this issue instead. Bootloops can come from many different sources so who knows!

Hello xda-devs community and XCnathan32 in particular

My Nexus 6P went into a bootloop a few weeks ago. At first I tried going through the official channels to fix it, such as the service provider I got the phone from and Huawei, but since the phone was out of warranty I hit the dead end pretty quickly. The I used the method described in this thread and it worked - thank you! I wanted to keep the phone as close to stock as possible, so I only flashed the Boot.img from stock 48C and did nothing else.

(Btw, to boot the phone to turn on OEM unlocking I just let is keep bootlooping until its battery was low and that's when it booted up. My theory is that when low on battery the phone turns on battery saver mode which prevents performance cores from kicking in, allowing it to boot.)

My question is, what do I do about updating the OS now? Currently the phone is prompting me to install the August 2017 updates, but if I try to apply them it goes back to bootlooping for a while, and then reverts back to July 2017 level. Also, how to update it to Android O? Again, I would like to do as little modding as possible.

One more question: the Neflix app no longer shows up on the Google Play Store. I assume it has something to do with the phone being unlocked now. Not a big deal, but just in case, is there any workaround for this?

Thank you!
[Nexus 6P General] JRizzo21:
hey, so the boot.img fix has been perfect. but my phone battery is averaging a 75 Celsius temperature. any way I can get that knocked back down a few double digits?
[Nexus 6P General] asido82:
Non of the roms worked

I just ended up flashing the Developer Oreo image files instead I went through a Guide in Youtube called Unroot, Unbrick and Return to Stock best guide so far if you dont want errors. the custom img files didn't work for me
[Nexus 6P General] Nightshadow931:
Unfortunately, I had to use this fix myself.

My 6P ended in bootloop few days ago, tried everything without luck.

After flashing this mod it finally booted, and works these few days without any problems so far.

I thought phone would be unusably slow, but it actually works really good.

So thank you.
[Nexus 6P General] ceribik:
Wouldn't that brick/zero-out your modem partitions...
[Nexus 6P General] StrifeSoldierVII:
No, it wouldn't. Whether you have a healthy or corrupted EFS... it won't cause any harm because it just rewrites the partition data not delete. If it's healthy and working nothing actually happens and if it's corrupted it puts it back into working condition again. Not to mention if your phone is possibly "dead" and nothing seems to work this could be worth a try because it displays some of the same symptoms as the bootloop bug outline in the thread here. EX: It stays bootlooping no matter what ROM or system image you flash because it is an entirely separate partition from the system itself.

Also: I've done it before in the past and I just now ran the commands multiple times again on my device just for you. It works perfectly, which I knew it would! As long as you have a partition of any kind working and available you can always partition it again as many times as you wanted to. Hope that helps. :)
[Nexus 6P General] dnsh89:
If in case efs is the reason for bootloop.. will it boot up normally after the 4cores fix..?
[Nexus 6P General] StrifeSoldierVII:
I couldn't say for sure without testing it, but maybe it will. If not... you could always start fresh by flashing a stock image and trying the EFS commands without flashing the modified boot image 4 cores fix. This could help isolate whether you actually have an EFS issue or the bootloop issue that requires the 4 cores fix. If your device is bootlooping right now and you can still get into recovery it seems ideal to try all ways possible to get it to boot again. You can't really mess anything up beyond what it's already doing.
[Nexus 6P General] dnsh89:
My device started bootloop like 3 weeks back.. I followed the fix in the op, now I'm on OREO with 4 cores mod.. I just want to know if it's worth trying this efs thing and if it doesn't workout can I come back to this mod again?
[Nexus 6P General] StrifeSoldierVII:
Then no, the EFS thing will not do anything more for your device if it is booting up right now with the 4 cores fix. If you can boot your device and have full network access on your wireless carrier then you're good to go so to speak... aside from the messed up cores of course. Sounds like you really did have the bootloop issue from the OP after all. Hey, at least you can use your device again so that's something. This thread is a lifesaver for a lot of users! The EFS thing was just a suggestion to the people who can't get anything to work at all from the OP. Those are the people that might possibly have an issue with the EFS partition instead, as rare as it might be.
[Nexus 6P General] dnsh89:
It indeed is.. [MENTION=5288606]XCnathan32[/MENTION] is the saviour and there's no lag whatsoever with modified EX kernel.. glad device is running the latest Android version inspite of the stupid bootloop issue..
[Nexus 6P General] StrifeSoldierVII:
Good to hear! I mean... in reality it's still a quad core SD 810 chip clocked at 1.55 GHz stock, so it shouldn't really be a slouch either. Especially since it's the EX kernel paired with Oreo, which is superb! Certainly even more useful now with the release of Oreo and its massive list of optimizations and under the hood changes. :good:
[Nexus 6P General] dnsh89:
I'll try the blackpepper governer, please guide me to the thread where I can find the latest build.. I found one from 2016.
[Nexus 6P General] StrifeSoldierVII:
Go to the following thread:

https://xdaforums.com/showpost.php?p=68070450&postcount=2760

These are the latest CPU governor profiles and some of the best you can find. BlackPepperV2 is the latest if that's what you wanted to try. Download the attached file in the thread. Or if you have the EX kernel app, the profiles already come with the app so there is no need to download them.
[Nexus 6P General] dnsh89:
Thanks a lot bro.. trying it now..:good:
[Nexus 6P General] JRizzo21:
has anyone that upgraded to Oreo had any issues with T-Mobile data compatibility? I want to do the upgrade (will probably need the boot img still) but want to make sure my data won't have an issue because I've read a few people have on google's forums?
[Nexus 6P General] Scooby__Doo:
I've successfully used this fix to get my Nexus 6p working again so thanks very much to XCnathan32 (life saver!). One question though... my Nexus 6p is completely stock and running on Android Nougat 7.1.2 with Security patch level: 5 August 2017. When I get pinged with the O.T.A update for Andriod Oreo from Google (whenever that may be) am I safe to update or will this update re-enable the 4 big Clusters again? Also is it safe for me to keep applying the latest monthly security patches as and when they arrive?
[Nexus 6P General] SlimSnoopOS:
OTAs may fail because of the presence of the modified boot image. Boot images from OTAs are configured to allow all cores to run.

Your phone will likely bootloop shortly after the phone successfully installs a new security update with no modified 4 core boot image. Each month, manually install the factory images then install the latest modified 4 core boot image.
[Nexus 6P General] paracha3:
Thanks for the fix. It got my Nexus 6p alive.
[Nexus 6P General] JanitorTT:
I've tried absolutely all the options in this thread and I still can't get this piece of crap phone working.

Flashed stock of all versions of Android with the modified boot.img files and still bootloops.

Can't get in to recovery unless I heat up the phone, so did that with twrp and flashed the modified ex kernels and still bootloops.

Then tried the EFS partitions fix and that hasn't worked either. I'm starting to get hella frustrated, but I need to keep trying just for personal satisfaction (I don't even need the phone anymore because I bought a pixel xl)

If I don't heat the cpu and let it keep trying to boot it will loop for about 30 minutes and then freeze on the Google logo until the battery is fully drained.

If anyone has any suggestions I'm at a point where I'll try literally anything.
[Nexus 6P General] ELHK:
Million thanks!

Thanks so much for the fix. my 6P got into bootloop for 3 weeks and I tried multiple suggested solutions and this fix is the only true fix.

Just to share, I tried freezer and heat method and no luck to boot up again, finally it is the draining of battery works (but only works after I replace a new battery, the old one cannot make it work). My 6P can boot to unlock OEM and enable USB debugging within a critical 2 minutes time frame.

Then I use the Windows Nexus Root tool kit to really OEM unlock the phone, then I can apply the fix from this post. I flashed The 6p48C.img as the boot image and flashed the TWRP 3.1.1 4Cores as the recovery image and then the phone can boot again.

I signed the petition as well. It's a shame Google did not reply me on the Google Nexus Support Forum at all.

I'm glad now I have a usable back up phone instead of a brick.

So I've been using this since you came out with this fix for the bootloop. I've noticed that when I'm on a phone call that my data is disabled. Is that due to the big cluster being disabled? I've tried reflashing my modem but that didn't help.

[Nexus 6P General] draxz:
Here is the solution I posted:

For the people with boot loader locked (You cannot do anything with it being locked) I just revived my phone: You need to heat the phone by using a blow drier for about 5-10 mins while in boot loop - in my case I don't have a blow drier so I turned the stove to medium heat and kept the phone about 10 centimeters above the heat. After 10 mins the phone miraculously booted up and went to "Setup as new phone" (I had wiped the device earlier) after setting it up, I immediately went into the setting to unlock OEM and after 15 mins the phone went into the boot loop again. I followed the instructions on this page and voila the phone works. Thank you XCnathan32 and other.

I contacted both. Google could only redirect, since they service phones only bought from Google store. As far as I know, google never sold nexus via Google store in India. So we are screwed. Huawei sent only robotic mail replies. Currently I am running this using the mod in this thread.

About legal proceedings, there are none in India that I know of. However there is one in the US I believe.

I am not sure if the fix for activating the main core or 4 cores (total noob here) was in place based on your main thread, I am running 7.1.2 and the phone is very sluggish even when typing anything.

Is it recommended that I upgrade to Andriod O since the latest fix uses all the cores?
