That's true. However this can be a precedent against manufacturers. It would be beautiful if this explode on google's face just before the Pixel 2 release. Some people just wanna see the world burn.:laugh:
[Nexus 6P General] XCnathan32:
Flash this firmware https://dl.google.com/dl/android/aosp/angler-n2g48b-factory-34c51cad.zip. It's for 7.1.2, keep in mind it will wipe your phones data though.
[Nexus 6P General] XCnathan32:
Did you flash the EX kernel over it?
[Nexus 6P General] jer0k:
still no luck for me. still on boot loop, still cant access recovery.

I've tried the heat gun approach, furthest I saw was the bouncing animation for a few minutes then it died.

my bootloader is unlocked so I was hoping simply flashing the files would help me.

to make matters worst I contacted Huawei in regards to extended warranty. They said they couldn't help me cause even with extended warranty I am over 1.5 months. I tried to escalate it but no go.

I noticed new suggestion using ice pack after heating. I'll be trying that. I've tried all the tip and tricks you guys are putting up here. I appreciate it.
[Nexus 6P General] AgentBEATS:
Is it safe to just flash the new boot image without wiping anything? I've got my phone finally running pretty nicely don't want to risk anything if not.
[Nexus 6P General] havenfx:
no worries, i flashed back to stock and upgraded to 8.0 again. was working for several hours and just started bootlooping again. I'll wait on your boot.img for 8.0 :)
[Nexus 6P General] Tbone_Green:
Thank You!

My Nexus 6P has been acting up for the past month or so - early shutdowns (usually when starting CPU intensive tasks with approx. ~20% battery), and really bad performance. Yesterday it shut down with over 60% battery after I took a few HDR photos and started into the BLOD... I knew about the BLOD problem and thought I was toast.

I started doing some research and came across this fix - My bootloader was locked, so I was a little worried I wouldn't be able to get it to work.

I threw my phone in the freezer for about an hour - the battery was already almost dead because I had left it BLODing since earlier in the day. I pulled it out and tried to start it up, but I got the red light blinking LED and the phone wouldn't start. I left the phone in the freezer and used a battery pack to plug the phone in. The phone booted right up and I was easily able to get into settings to enable unlocking. I also had enough time to go to the play store and install SMS backup and restore and make a full backup of my calls and SMS. At this point, I was over cautious and pulled the phone out, thinking that it might be working fine again. 5 minutes out of the freezer and it started BLODing again.

- At this point I followed the steps found here: https://www.xda-developers.com/nexus-6p-bootloop-fix/

- Using the .img (first link in the downloads spoiler) found in the OP in this thread.

- In step #11, I obviously substituted the new file name for the .img

- I did not do the optional step in step #11

- I did not do the optional step #14

My phone has been working fantastic since - I've reinstalled a pile of apps, and I don't notice any decrease in performance at this point.

Being a complete beginner to any of this, I wanted to share my experience.

Thanks so much OP!!!
[Nexus 6P General] XCnathan32:
I've spent at least 15 hours trying to get just Android O to work. It seems to have a problem mounting the partitions/reading the fstab. I have no idea how changing a kernel parameter would change that, but at this point, I think I'm just going to wait until the official release of Android O to see if they ironed out the bugs.

Tl: Dr: doesn't look like an Android O fix will come for a little while, so you might want to go back to Android N in the meantime. Sorry :/
[Nexus 6P General] marktsadkin:
Does it mean that with every security update we will need to wait for you to release a fixed boot img? or with PN rom? custom kernel and etc...?

Thanks again and great work on that update! Made my phone working as well as before!
[Nexus 6P General] havenfx:
called google and they are expediting a new phone to me. score!
[Nexus 6P General] ramhses02:
XCnathan32, Is it possible to use this fix if the bootloader is blocked? Or is it possible to unlocked it if I just see the google logo?
[Nexus 6P General] Azime09:
[MENTION=5288606]XCnathan32[/MENTION] I did all the steps in the post along with the steps provided in

https://www.xda-developers.com/nexus-6p-bootloop-fix/

with bootloader being unlocked and flashed it with the images, it went to twrp recovery in which I clicked it to just start up the phone and it loaded completely fine (hurray!) til it asked for a password to unlock the device which I wasnt sure why it asked that then completely froze and went straight back to boot loop :( . I've attempted to flash it again with no luck and just constant bootloops, im curious if I did anything wrong or if there is another way to go about it.
[Nexus 6P General] darkriff:
This is the actual status of the phone. Thanks! I think I'm going back to stock :D
[Nexus 6P General] darkriff:
You Need to try to boot it up using a lot of heat, then enable oem unlock under developer settings
[Nexus 6P General] ramhses02:
Thanks you!! It was really weird but impressive. The phone is working now. I use the hair dryer and it worked. A thing I just noted is that the fast charging is really slow. It says 7 hours to complete full charge.

My current worry, the phone will go into the bootlooping again? I don't know if I have to attach a hair dryer to my leg or try the fix on this post right away.
[Nexus 6P General] darkriff:
After you apply the 4core fix, it should work with not expected bootloops in the future, but hey! only God knows :laugh:
[Nexus 6P General] ramhses02:
So. If I use the phone without applying the fix, will it bootloop again? Is that 100% probable?

---------- Post added at 05:23 AM ---------- Previous post was at 05:03 AM ----------

Further to my previous post, I'm currently on the O dev. preview 3. Just received the notification to download the last OTA. To apply the 4core fix is preferable to downgrade to Android N?
[Nexus 6P General] Snow_ball:
That depends how urgently you need your phone. You can chance it and stay with o if you can live with the fact that it may leave you stranded somewhere if it falls again. If you are always close to a computer and can flash 7.1.2 at any time, you can see if it happens again. If you definitely need a phone at all times, you know it will fall you in the most painful situation. Murphy's law...
[Nexus 6P General] darkriff:
I would strongly recommend that you apply the fix or at least keep the bootloader unlocked for if you suddenly get into bootloop then you are prepared to push the fix and keep using the phone.

The fix is not working with Android o now, OP will wait for the stable release to come out to start working on it. So yes you need to be in N
[Nexus 6P General] ramhses02:
Well it was really fast. I got the bootloop again. Hair dryer is ready for tomorrow. I kept the bootloader unlocked. Tomorrow I will try to return to N.

I expect to fix it and then I will sell this phone.
[Nexus 6P General] Jazza159:
Hey, Snow_Ball and everyone else.

I just made an account to ask a quick question and thank the OP for his work (THANKYOU!!), forgive me if I sound a little silly as my knowledge regarding these things is very limited. After reading a billion posts saying my phone was stuffed I found a tutorial that referenced the first version of the fix (1.5 cores). I was stoked to have my phone back but the lag made it pretty unusable. I was reluctantly going to make a trip to the shops this afternoon to pick up a new phone when I stumbled upon this thread with the updated 4 core fix. I just flashed that and TWRP and the phones running much faster (6P on N7.1.2).

The question is, will it hold?

I need a dependable device, have people who have flashed the fix over the last weeks had a relatively stable platform?

From what you're saying Snow Ball its rather hit and miss :(

I'm worried it's just going to re-enter a boot loop and I'm going to, rather literally get stranded somewhere.

Any info would be great, thanks all!
[Nexus 6P General] IM0001:
The question of will it hold will have to wait until a handful of those that use the fix for a period of time either run into issues again, or don't. Until then it is way too early to know for certain as we both still don't understand exactly what is causing our phones to "break" all of a sudden (it could be a solder issue of sorts, it could be some other part failing) and if this "fix" will break the same part further, or something else. Until then though, we technically are around a high end Snapdragon 400 processor of sorts with 4 small but zippy cores vs the full 8 the 810 offers normally so once the performance of all 4 are utilized its not surprising that it remains a zippy little bugger.

I do have a question for the OP however, would you be willing to let us know what you are changing to Improve the Fix currently? I had to edit my own .img's for a different rom version to back up my device previously with the maxcpu=4 flag, but from what I can tell, there must be changes elsewhere for the performance of all 4 cores to be realized now over what the old fix did. I am curious.
[Nexus 6P General] @Peterrrrr:
What is it that causes the bootloop to happen, is it because the phone gets older and worn or isnit after an update?
[Nexus 6P General] leroilion02:
please samone help

I tried but just boot loop

my bootloadrer unlocked

in fastboot i tried this

fastboot flash boot 48B_A4.img

fastboot flash recovery twrp3_1_1_4Cores.img

fastboot reboot

just bootloop i need my phone help me
[Nexus 6P General] Archavius:
I got boned.

I fixed my phone with the guide, had to heat up phone to boot to TWRP and then to install the kernel. All was going fine for around 20 hours, I could reboot my phone perfectly fine no boot loop, CPU-Z showed CPU4-7 as stopped, and apps were running smooth. However, when I went out, and I reached for my phone I realized it was turned off for some reason. I turned it back on and it boot looped -_- I have no idea if the modified image was written over or if the fix is vulnerable to other applications. I've noticed with my experience that whenever I just recently downloaded FB messenger app, the phone a few moments later usually boot loops.
[Nexus 6P General] Jazza159:
hmm, messenger isn't causing issues for me, im running version 128.0.0.21.88 of the facebook messenger app. Only just flashed the 4core fix, will report back in 20 hours if it starts boot looping again :P
[Nexus 6P General] corona_gorda:
EX Zip mandatory?

Hi, I successfully did the following 3 steps:

fastboot flash boot 48B_A4.img

fastboot flash recovery twrp3_1_1_4Cores.img

fastboot reboot

TWRP launched fine, with none of the difficulties documented in this forum, but I wonder:

1- Do I need to flash the EX zip file at all ? If so, where in my phone's file directory do I need to put the zip file ?

2- If I reboot at this time will it come alive again "as is" or is there another step to load Android 7.1.2 as my phone does not have an android OS at this point ?

3- If I need the EX Zip file I have the one posted on July 29th; where can I download the most recent posted on July 31st with the best performance kick ?

Thanks,

Mike
[Nexus 6P General] burduli:
I'll try. If that works, I'mma donate away.
[Nexus 6P General] draroraab:
N2G47W build

Hi! Thanks for the fix. I have already been using ElementalX kernel to disable my BigCluster, although booting was a problem. Heating the Phone to increase CPU temperature beyond 40°C allows it to boot up.

Anyway, I wanted to ask this. I am running the N2G47W build of stock ROM. Would the boot image you provided work with the said build?
[Nexus 6P General] XCnathan32:
Since 47W is 7.1.2, I would assume so, but EX kernel 4.11 is for all versions of 7.1.2, so I would just flash that instead. The modified TWRP should work fine.

How did you heat the phone safely to that temp? I want to do some testing with that to see if I can find anything useful from that.
[Nexus 6P General] draroraab:
I just let it try to boot and put it on charging, keeping the phone under my pillow. It's a bit risky, but the phone boots up in about 3 to 5 minutes.
[Nexus 6P General] xringo:
I wonder if magisk would work on this?? If I wanted supersu on this device, which version should I get?
[Nexus 6P General] ggpew2:
Can we use the modified boot.img on non-bootlooping devices?
[Nexus 6P General] burduli:
I replaced boot.img in the OTA file which doesn't require unlocked bootloader to be flashed, but I got "Signature verification failed" error while flashing. Is there any ways to disable signature verification check?
[Nexus 6P General] XCnathan32:
Other than unlocking the bootloader... I don't know of any, I'll look into it to see if I can somehow find a way.

Edit: Also, someone a few posts above me said he was getting his device to boot by heating the cpu up to 40 degrees Celsius, and then it would boot up (with stock boot.img) So maybe you could try that and if it boots up then enable OEM unlock.
[Nexus 6P General] burduli:
Okay, thank you. Can you add me on any messaging platform? Messenger, Telegram, etc. Whichever you use.
[Nexus 6P General] xian2380:
Thanks for your work:laugh:
[Nexus 6P General] burduli:
You mean that I don't need to flash anything, I just need to heat up device?
[Nexus 6P General] MaKTaiL:
I am unable to decrypt my data on the TWRP. WTF? I can't use it to flash the kernel, or any other ROM for that matter.
[Nexus 6P General] XCnathan32:
Click cancel when it asks you to decrypt, then factory reset the device to get rid of encryption. If you flash EX kernel, it will disable the TWRP encryption.
[Nexus 6P General] XCnathan32:
I would assume that just heating up the device would cause issues like random shutdowns, and going back to bootlooping. If you manage to get your device booted using that method, then you can enable OEM unlock, so you can flash the modified boot.img.
[Nexus 6P General] burduli:
Okay, I'm gonna connect the charger and put the phone under pillow, I'll see if that works
[Nexus 6P General] xringo:
Bro can you tell me what superSu you are using? And if magisk will work? I want to root this and install the elemental x app and mess around with the cores.
[Nexus 6P General] MaKTaiL:
I was able to sideload the kernel zip using the TWRP tool in Advanced Settings. =D

---------- Post added at 04:03 PM ---------- Previous post was at 04:02 PM ----------

Use a hair drayer.
[Nexus 6P General] XCnathan32:
I'm using the latest stable SuperSU 2.82 zip. I haven't tested magisk yet, but I see no reason for it not to work.
[Nexus 6P General] burduli:
Will it be able to heat up device to 40 degree Celsius?
[Nexus 6P General] MaKTaiL:
It's definitely possible to heat it up. I used it to revive mine (I didn't have the OEM Unlock enabled either). Start the phone and let it bootloop while you heat it up. Once you see that colorful android logo it mean it finally started.
[Nexus 6P General] marktsadkin:
Does it mean that we need to wait for you to post every new PN rom update that has been modified? so with custom kernel and etc...?

And someone here said he flashed regular TWRP and it worked for him, so why do we need a modified TWRP?
[Nexus 6P General] corona_gorda:

[Nexus 6P General] leroilion02:
M.XCnathan32 do you have any idea for fix my problem
[Nexus 6P General] xringo:
Try flashing a new rom, then flash the boot img. Then reboot the bootloader. Once you reboot the bootloader, flash the twrp.img. Then again reboot the bootloader, then reboot into recovery and see if you can access the recovery first.
[Nexus 6P General] XCnathan32:
Personally, I haven't had any problems in the almost 2 weeks I've been using it. I haven't heard anyone else report that their device is unstable with it either.
[Nexus 6P General] mbkennel:
I don't know about 100% probable, but pretty probable if you had the problem before as it appears to be hardware, in particular the Qualcomm 810 CPU. The big 4 cores have a big thermal problem it appears. Samsung didn't use it after some testing. I don't know the problem with the bootloop but it may be that the A57 (big) cores were chronically overheating so often the chip itself failed in that section.

If it's long-term heat related, then perhaps not using a case and keeping it cool would prolong the 6p life before succumbing to BLOD disease.

Question to our glorious developer overlords: suppose you made a boot.img with NUMCPUS=5 or 6? I wonder if that might work but give one or two fast cores which would stay more stable?
[Nexus 6P General] XCnathan32:
Ex kernel is recommended as it will make your device run a bit faster, the new EX file is in the downloads section of the OP, it's just by EX kernel.
[Nexus 6P General] XCnathan32:
Will it boot to TWRP?
[Nexus 6P General] corona_gorda:
And then, I'd reboot to an Android 7.1.2 phone with a performance enhanced, 4 out of 8 cores arrangement ?
[Nexus 6P General] XCnathan32:
Hmm... You definitely did all the commands right. Will it even boot to stock recovery or no?

Also I'll go ahead and add the checksums in the OP tomorrow when I'm not on my phone, thanks for them.
[Nexus 6P General] btvolta:
This worked flawlessly by just fastboot flashing twrp recovery and modified exkernel. Thanks for making this available.
[Nexus 6P General] csunit37:
Tried everything from heating the phone to freezing it. Still bootlooping. Sigh!
[Nexus 6P General] leroilion02:
no just android logo and bootloop
[Nexus 6P General] btvolta:
This morning I flashed DU and the modified exkernel and so far it's running well.

Edit : The modified ex kernel appears to work on all roms. I've tried 3, and I'm currently on Validus and it seems to be running just as fast as before the blod I experienced.

Bootloop of death - Nexus 6P phone is bootloader locked.

hello. Please help. My Nexus 6P just started to experience Bootloop of death. I would like to try this solution but my bootloader is locked. One of the ways the site mentions is "the most successful method seems to be heating up your phone (a lot)". What is meant by "a lot"? Has anyone reported success using this method? What's the best way to heat the phone up? Freezing doesn't work. Draining battery doesn't work either.

Any ideas is greatly appreciated it.
[Nexus 6P General] Archavius:
You're going to have to use a blow dryer or a heat gun and aim it at the area between the fingerprint scanner and the camera visor. It's going to take around 5-20 minutes depending on the appliance, but once the processor goes over 50 degrees celsius, the processor will shut down the big clusters and be able to boot up using only the small clusters,
[Nexus 6P General] martinfarrell11:
Hey, have you done it with the hair dryer? I tried it like four times now and the phone shuts down after 10 minutes and I let it freeze on the desk but it keeps bootlooping

Also, I may try a heat gun tomorrow, would be recomendable to do it for 5 to 20 minutes or a bit less?
[Nexus 6P General] Archavius:
I've done it with a hair dryer, I got the phone to be 70 degrees celsius with it somehow, just be persistent, but also don't let the battery overheat, have an ice pack handy to put it on and then keep blow drying. I've never used the heat gun but many others on this thread have. Make sure you also have ample power, I don't really agree with the whole battery being at 10% or less thing, I think if you heat it enough the snapdragon will force itself to use the smaller clusters.
[Nexus 6P General] daproject:
finally I got my phone working again... thanks so much.

my question is, can I flash whatever rom I want as long I flash the kernel.zip? or I need to flash a modified boot image?

thanks!!!!!
[Nexus 6P General] btvolta:
I've successfully flashed 3 different roms by just using the modded ex kernel, so it should work on all roms. Btw, I'm still using the 4 core twrp version too.

my phone not getting on its showing only google what to do now any one help me please
[Nexus 6P General] Sumedh Pendse:
Not able to access recovery :(

Hi Guys,

First of all thank you XCnathan32 for showing hope to all of us who are stuck in bootloop and are not getting any help from biggest smartphone players Google and Huawei.

I used 6 year old hair dryer to wake my phone :p I aimed it between camera and fingerprint sensor for 10 mins. My battery was super low....almost close to 0%. I believe heating trick works only when battery is below 10%. So anyone who wants to try hairdryer technique, please drain phone battery completely. Try to switch it ON. If you press power button and it shows only red led, then connect the phone to charger. Let it bootloop for 5 minutes. Then start and aim hairdryer between camera and fingerprint sensor for 10 minutes or more (let phone be connected to charger). Stop once you see colorful Google logo. Your phone will start (remove charger once phone starts).

My phone started and I went to developer settings, enabled USB debugging and OEM unlock. Then phone again started bootlooping after 5 minutes and not able to get out of it.

I installed Google drivers and downloaded platform tools folder. Then I unlocked the bootloader with fastboot and flashed TWRP from given link with fastboot command. Then in bootloader, I selected recovery and phone showed me below error:

"Your device software can't be checked for corruption. Please lock the bootloader."

It also says please press power button to pause boot. After this error, phone shows me white Google logo in screen along with unlocked logo in bottom. Again phone goes to that error after 6-7 seconds and this keeps on repeating until I enter in bootloader mode.

I even tried to recover my phone with Wugfresh's nexus toolkit v2.1.9 as per instructions given in page 28 in this thread. I am able to flash everything. No error at all while flashing but my phone does not enter recovery at all and I am stuck in bootloop along with orange logo.

Can someone please help me with this issue as I know very little about this.

Thank you in advance!
