Yes, I did this a few days ago to flash the February OTA, worked fine. Just make sure to flash the BLOD_workaround last.
[Nexus 6P General] AndroidHtc101:
Jeff how's your nexus performance? Mine is basically very slow, do you use kernel? I need some help
[Nexus 6P General] tomz997:
Update done but my 6P seems to be slower than before! :(
[Nexus 6P General] AndroidHtc101:
Disabling all animations in developer options really did help with speed and fluidity I was surprised!
[Nexus 6P General] squabbi:
I've got one here, although you should consider using the flashable zip now: https://www.androidfilehost.com/?fid=818070582850491675
[Nexus 6P General] jeffreymcclain:
I've been using it a few days and haven't noticed a slowdown. Granted, my phone was already a bit laggy before and the only app I use regularly is Reddit Sync.
[Nexus 6P General] zenon3109:
I have magisk and elementalX kernel installed. Fix with osmosis zip. Can i update magisk or elementalx kernel?

Thanks!
[Nexus 6P General] jeffreymcclain:
ELI5 explanation of any kernel 2 (AK2) fix?

Just curious, can someone give me a simple explanation of what it does? I tried reading the source post but didn't really understand it.

I'm wondering if AK2 just modifies the stock kernel (I assume the most updated kernel is included in the latest OTA update), flashes its own specialized 3rd party kernel, or if it flashes an older / static version of the stock kernel (perhaps taken from some old OTA or factory image).
[Nexus 6P General] Clinton L.:
I haven't tried the February patch yet. Does it fix the problem where the phone dies despite having roughly 50% power remaining?
[Nexus 6P General] Rashad83:
There are 8(octa) core processors, 4 cores for handling high level tasks and the other 4 cores responsible for the lower demand tasks. What the patch does in simple terms is disable the 4 cores responsible for high level tasks because I believe one or more of those cores is responsible for causing the bootloop in the device. If you use EX kernel manager you will see the 4 cores are disabled.

The patch doesn't replace the kernel you are using whether custom or stock it simply patches the existing kernel used to my knowledge.

If your phone dies at 50% roughly speaking, this means you are not dealing with a BLOD simply you need to change the battery. Go to Huawei Service Center or any repair shop to do the change afterwards you will not face the issue you describe. You don't have to use the patch described in this thread, this thread is meant for phones that are in continuous bootloop even after factory resetting or flashing a new stock rom.

P.S: The patch zip works fine with the latest February security patch as I have already installed it and should work fine with future updates as stated by the OP.

My device is also rooted using Magisk, latest ElementalX Kernel, have Xposed and GravityBox installed with no issues for anyone wondering.
[Nexus 6P General] AndroidHtc101:
Rashad could you please run through the Elementalx kernel flash. I'm slightly confused.

I did the 4core zip flash and modified twrp.

Booted now but my phone is very slow apps take around 15 seconds to load. I'm not sure how to flash the kernel and which twrp to use, I'm on Jan 8.1.1

Would the kernel speed the phone up a little? I've turned off all animations too.

Thanks for your help :)
[Nexus 6P General] Rashad83:
You need to follow the guide in the second post as instructed, Here is what you need to do:

*Download the following zip files by osm0sis: -twrp-3.2.1-0-fbe-4core-angler.img

-N5X-6P_BLOD_Workaround_Injector_Addon-AK2-signed.zip

I suggest you start fresh:

1.flash all the latest stock files; bootloader, radio,boot,system,vendor like in the guide.

2.flash the downloaded patched TWRP file mentioned earlier by osm0sis.

3.reboot to recovery and do a factory reset then flash any custom kernel you want(eg:ElementalX Kernel, get the kernel from the developer website 'Oreo 8.1 version' if the rom is 8.1)

4.flash Magisk, Xposed or GravityBox if you want if not go to the next step.

5.flash N5X-6p_BLOD zip file by osm0sis(The 4 core patch), as mentioned by OP the "final step" is to always flash the 4core patch.

6. Reboot.

Hopefully everything should work fine.
[Nexus 6P General] AndroidHtc101:
Thank you for your detailed explanation :)
[Nexus 6P General] pitflyer:
This procedure worked for me, appreciate the step by step directions as a call out from the original fix. I've always been using 'stock' with the only changes being installing Magisk for root. Now that my phone is obviously hobbled by using half the cores, is there something I need to add instead? Do I need to add the 'ElementalX' kernel after I flash all the stock stuff and custom 4 core TWRP, but before I flash Magisk and the BLOD fix?
[Nexus 6P General] AndroidHtc101:
I heard flashing the elementyx kernel could over heat the cores in time and fail.

It's slow with 4 but at least its working as a normal phone :)
[Nexus 6P General] maity-iman-2015:
Did anybody face this 4 core failure without using any mods? My case: after using ElementalX kernel for 2 months, I noticed photos were taking longer to save, and finally, on September 2017, I got first boot loop of death. Or it's just a hardware issue, randomly so many are facing.
[Nexus 6P General] Rashad83:
It's a well known hardware issue it has to do with snapdragon 810 design flaw I think, I celebrated my 2 years old N6p last month and out of the blue I got the BLOD last week. If you own a N6p you will face the BLOD at some point of the device life, so for those still owning it without facing the BLOD you better sell the device before it's too late and at least recoup some money to buy a new device.
[Nexus 6P General] jm93944:
Thanks so much for the guide! I was able to quickly get my phone working again while traveling.

I was running stock 8.0 with no issues. Installed 8.1 OTA update, then had a random reboot happen later that day. The next morning it suddenly powered off right after unlocking the screen. Tried to turn it back on and got the BLOD. I powered it down and charged it then it booted up and worked for almost an entire day before the BLOD began again.

The phone is performing slower, but is still usable, and good enough to trade-in. I ordered a Pixel XL, and a Moto X4 to replace my wife's Nexus 5X, since that will probably fail at the worst possible time also.

Thanks again for all the help.

[Nexus 6P General] pitflyer:
My 6P never had any mods -- just unlocked bootloader, stock ROM that was rooted (first via SuperSU, then Magisk), and used TWRP as my recovery. I bought mine new in August 2016 and was hoping to squeak through two years, but as of a few days (Feb 2018) I got the BLOD and now limping along with four cores. Performance is noticeably slower so I'm going to get a new phone. I'd think about trading it in at Project FI, but the problem is if I reset the phone to default it will bootloop. So I don't think I'm able to trade it in?
[Nexus 6P General] Ronin3178:
Mine went into bootloop yesterday. I was able to get into recovery after letting it sit a few hours completely off. Wiping cache and I'm back up. Only thing I did for now is unlock the bootloader, otherwise it's completely stock and up to date. If you wipe and restore to stock it should work enough for the check on trade in, just my opinion.
[Nexus 6P General] Rashad83:
So basically you are advising him/her on how to cheat someone else, i believe your intentions are good but that is not a good advice. If you want to trade the phone you need to inform the new user of the phone flaw, imagine yourself in the place of the new user/buyer.

I would advice keeping the phone as a backup phone until it dies on you, or find a buyer willing to buy it with him/her knowing about the bootloop.
[Nexus 6P General] pitflyer:
Fair ethical question, I guess. In my case I was planning to trade it into Project FI -- where I hope they would refurb the phone completely before reselling. My phone's in good shape other than BLOD so it shows as $135 trade in value, and they have a promotion for $80 in FI Credit, and you can get $20 in referral credit. So I can get $235 in credit and apply that to their cheapest new Moto X4 phone ($249) basically swapping out. While I want a faster phone than the X4, at least I would 'cash out' of my situation, and likely give that phone to my mom and then buy a better one myself.

I still don't know what 'better' one would be anyway....
[Nexus 6P General] asharx:
I have the boot loop issue and I followed the procedures in Post #2.

First update the bootloader: fastboot flash bootloader *drag in extracted bootloader image*.

Reboot back into the bootloader: fastboot reboot-bootloader.

Flash the updated Radio image: fastboot flash radio *drag radio image here*.

Flash the updated boot image: fastboot flash boot *drag boot image here*.

Flash updated system image: fastboot flash system *drag extracted system image here*.

Flash the updated Vendor image: fastboot flash vendor *drag extracted vendor image here*.

Flash the updated PATCHED TWRP: fastboot flash recovery *drag patched TWRP image here*.

Reboot into recovery mode using the volume buttons to change the selection and press the power button to select.

Flash the BLOD Workaround ZIP (remember to flash this ZIP last).

Reboot

Everything looks like it worked OK but now I am getting No Sim Card - No Service.

It isn't recognizing my sim card (works fine in my Samsung S5). The IMEI isn't being displayed in Phone Info.

In the bootloader I can do the barcodes to see what my original IMEI was.

I am going to redo the steps tonight to see if it was something that I did.

Anyone else have this issue?
[Nexus 6P General] AndroidHtc101:
Go backing into TWRP and wipe data and cache, I had this Problem too. If that doesn't work start fresh with the guide.

---------- Post added at 11:42 PM ---------- Previous post was at 11:41 PM ----------

I didn't have the no sim no service in this situation, but on previous upgrade of android this happened a few TWRP wipes helped to correct it for me. GL
[Nexus 6P General] Scyzor:
Did anybody with BLOD tried to downgrade to Nougat? I think BLOD must be related to Oreo power management including Large Cores. Below is why I think this is it.

My phone has disabled 4 large cores but often suffers from random shut downs. It mostly happens when I have open more power consuming apps like FB, FB Messenger, Google Chrome, Outlook, etc It can happen when from example I browser some site and then get FB Messenger message or an email notification (often it goes with strange noise from a speaker which sounds like phone is going to explode) and battery is below 90%. When I power on back it shows better was dropped to somewhere between 50-65%. Phone will stay on till I will open any power demanded app then will shut down. It will work 2-3 more times then will shut down on android spinning letters (when I will connect to charging it shows that phone has around 30-40% of a battery). Then I will try to continue to get it on till it will goes into BLOD (with disabled 4 cores) and I need to use hairdryer to have it back on. When I plug in to charge when it shuts on android logo and will charge to full, disconnect and turn it back it shows that it is still charging in the battery system info app.

All of it never happens when a phone is connected to the charger.

Any thoughts?
[Nexus 6P General] AndroidHtc101:
That's a very interesting thought. Could someone try down grading to nougat.?

Come to think of it, my BLOD happened in oreo, 8.1.1 when I had lot of cpu intensive apps running.

---------- Post added at 09:49 AM ---------- Previous post was at 09:46 AM ----------

I would happily downgrade to nougat to get the power back., 4cores opening apps takes ages
[Nexus 6P General] shuli81:
Hate to break to u guys, but this has nothing to do with Oreo.

I got blod way before Oreo even came out.
[Nexus 6P General] SlimSnoopOS:
That's new for you, but old news for this device. You're describing the early shutdown issues from a crap battery:

[Nexus 6P General] asharx:
Update:

Success! Restored my IMEI, fixed the No Sim - No Service issue.

I downgraded to 7.1.2 (there were some other issues that happened here, the phone app kept on erroring out) and it at least recognized my sim and my network, imei etc showed up.

I then reflashed everything in post 2 ( I am using this build 8.1.0 (OPM5.171019.015, Feb 2018)) . It kept the IMEI number but there were other things that were unusable (when I swiped down from the top I couldn't go into Settings, the circle & square buttons on the bottom of the phone wouldn't work).

Digging around to resolve the Drop down, home & recent issue I found another threat to trigger the SetupWizardUpgradeActivity.

https://xdaforums.com/pixel-xl/help/home-recentes-buttons-t3668547

1. Install Nova Launcher

2. Opened Nova from App drawer (or can set as default launcher).

3. Hold down on empty space -> Widgets -> scroll to Nova Launcher look for Activities shortcut. Hold down and drag onto home screen somewhere.

4. Scroll down to Android Setup and select on "SetupWizardUpgradeActivity".

5. Complete the setup options and then it is perfect.

Thanks!!!
[Nexus 6P General] StephenMSmith:
Wow, 2nd Nexus 6P that ends up in BLOD. Luckily, I know how to resolve thanks to these threads. So I'm back up w/just the 4 cores. But I do find the phone noticeably slower. One thing I've haven't done either time I resolved BLOD is change the kernel. Would flashing a 4 core kernel improve my situation? I'm stock root ROM and plan to stay that way until Pixel 3 at end of year.
[Nexus 6P General] AndroidHtc101:
I would like to know if flashing a Elementalx kernel helps too. Any experiences guys much appreciated :)
[Nexus 6P General] Ronin3178:
I have downloaded the patched image, but how do I install it? Through fastboot, if so where do I direct it? Not really up to date on this stuff, haven't really messed with rooting etc since my Moto Droid. But this BLOD has forced me back.

I have Nitrogen ROM installed, but without the patched image, I'm constantly going back into BL during setup.

Edit : Nevermind, I figured it out.
[Nexus 6P General] scsi_2k:
I never experienced the bootloop but I did have random restarts due to battery. I did the 4 core fix anyway as a precaution. Is there a tutorial to go back to 8 core?

I have replaced the battery a second time due to the first battery charging capacity going to only half after a few weeks of use. This second battery has been great at still 100% capacity after a few weeks.

Now looking to go back to the normal 8 core.
[Nexus 6P General] Rashad83:
Just flash the stock rom files, follow the guide number 10.

Don't forget to wipe the user data using the command line provided in the guide.

So this was working for a few days then suddenly the sound has completely given up on the device. It won't play anything through Youtube, Play Music, anything. Playing music and it just stops straight away. Playing YouTube just plays the video without sound. I tried using headphones but no different.

The only thing I could think was that I updated Magisk to 16.0 however I'm sure that's not related. Could something else have physically gone wrong with the device?
[Nexus 6P General] Herp-tologist:
Hey guys very new to this

So I flashed the TWRP .img from osmosis but it seems I can't boot into recovery. Does this mean I'm basically boned here? I can't flash the zip file if cant get into recovery right? it might be my nexus 6p is especially broken.

do i need to flash the bootloader, system, radio etc from the factory image for the recovery to work?

Thank u for helping me resurrect my 6P

Just one question: I flashed the 7.1.2 factory image, if I try to update to 8.0 i have to flash the Workaround again or it's safe ?
[Nexus 6P General] Rashad83:
If you flash a new rom/kernel you will need to patch them using the workround. So the answer is yes.
[Nexus 6P General] luk4352:
And this include also the OTA update I suppose

Thanks for this great stuff. Question how does this kernel speed up the 6p on 4cores? Because mine is running so slow on 4...do you see any noticeable differences?

I've never seen flash a kernel before so wanting some advice.

Thanks guys :)
[Nexus 6P General] Bluemgt06:
I run the unified thermal mod to help it run faster, and adjusted the animation speeds. Also I believe there is a thread about getting better performance after the 4 core "fix".
[Nexus 6P General] AndroidHtc101:
Could you provide me with the threads name please? I've searched for 4cores thread didn't see it. Thank you :)
[Nexus 6P General] Rashad83:
Why go through the trouble when simply you can flash the updated kernel and then patch it using the work around patch zip.
[Nexus 6P General] Bluemgt06:
So when reflashing I don't have an extra step.
[Nexus 6P General] Rashad83:
Exactly, with every rom/kernel update you do simply flash the work around zip and you're good to go.
[Nexus 6P General] Scyzor:
So after 3+ months on 4 cores my phone went to BLOD from which hair dryer trick cannot resurrect back. RIP :(

At least the case got moved ahead https://www.xda-developers.com/google-huawei-nexus-6p-class-action/ but I don't want to get discounts from Google or Huawei
[Nexus 6P General] Rashad83:
You can't system update if you have TWRP installed, you will need to install the stock recovery for it to work i believe.

The second post are the steps for flashing a stock rom, so with every update you download the updated rom files and install them manually then flash the work around zip as the final step.

The third section is the old manual way of patching your boot which isn't necessary with the work around patch unless you don't want to use the work around patch zip method.
[Nexus 6P General] squabbi:
Sorry for the late reply! Did you still need images to be patched? If so send the over if you can't do it yourself, or use the TWRP flashable patcher. :)

Is there any explanation ..Why??

I need help with this....

i'm using Opm.1.171019.011 factory image
[Nexus 6P General] Rashad83:
Most likely it means the patch didn't happen or you flashed a zip file (ex: kernel) without re flashing the work around patch zip. Remember "make flashing the work around patch zip the final step".
[Nexus 6P General] Lord Aguacate:
Hi guys, I updated my phone to the 8.1.1 (February update: angler-opm3.171) and now my phone feels really slow (slower than before), any suggestions?
[Nexus 6P General] Rashad83:
1.Backup your apps and do a factory reset, see if that works.

2.Disable system animations or lower them.
[Nexus 6P General] Lord Aguacate:
Thanks for the info!

I know, I fixed from the bootloop a few months ago but with Oreo its feels really slow.

I will try yours suggestions like Nova!

Thank you again!
[Nexus 6P General] AndroidHtc101:
Could you please run my through how to install the ex kernel you suggested? Will the kernel have any settings as default? My nexus 6p is so slow apps can take about 10 seconds to open
[Nexus 6P General] Rashad83:
I would suggest you do a factory reset first to remove any apps causing the slowness, flash ex kernel zip from the developer thread and through the setup just accept the default settings, you can enable double tap if you want it and then go back to recovery don't boot to system yet, install the work around patch zip, clear dalvik and cache if you want to then reboot.
[Nexus 6P General] AndroidHtc101:
Hi rash will performing a factory reset lose my photos and music?

Thanks
[Nexus 6P General] Rashad83:
Technically they should be still in the data partition so you should find them after the factory reset. But It's better and safer to connect your phone to the PC and backup your files and photos then use Titanium Backup to backup your apps that's the fastest way to do it.
[Nexus 6P General] AndroidHtc101:
I went through a guide on 8.0.1 I'm really not sure what work around zip to flash now and the kernel 4core one. So think I should leave it incase I can't boot again!

But thanks for your help guys
[Nexus 6P General] roshanmoolya89:
i did flash the Work around patch in the end ....after flashing all the required images ...but still ..every time my phone heats up(after playing a game for 3 for 4 mins, using my camera or using instagram ...etc) ,it reboots . i am not able to use my phone on daily basis .
[Nexus 6P General] Rashad83:
Ah then that's a different matter, it's time to get another phone. The work around isn't a solution but a temporary one to salvage your files and apps, I am currently using my phone as a backup phone and for simple basic use like calls and browsing I don't even play games on it any more.

Expect your phone to stop working after a couple of months if not less depending on your usage, alot of users have reported it even after using the 4 core patch.
