As quoting osmOsis you should definitely follow this order:

"The correct order is as I said: ROM -> root -> custom kernel -> 4core AK2"

1. Make sure your phone is unlocked

2. Make sure you have the latest SDK kit (I had a outdated version and it did not work, so get the latest one)

3. Install your stock ROM (alternatively I used lineage 15.1 and worked just fine (lineage-15.1-20180423-nightly-angler-signed.zip)

4. Install recommended TWRP (twrp-3.2.1-0-fbe-4core-angler.img)

5. Install your root (optional) - use SuperSU or another one

6. Install your custom kernel (again optional - EX, or Franck)

7. Then install 4core AK2 (N5X-6P_BLOD_Workaround_Injector_Addon-AK2-signed.zip)

8. Reboot

Should work..
[Nexus 6P General] jimbomodder:
Unlocked and rooted? If yes then try a custom ROM.
[Nexus 6P General] Makarrim:
So I'll start with this :

1. FASTBOOT my device and flash the latest stock 8.1 rom and it automatically reboots and still bootloops ,here I again go to boot loader and flash TWRP 4 core.

2. Select recovery from bootloader and wait for it to bootloop again until I heat it with the hairdryer to the revovery which is super laggy.

3. Connect my pc and copy the Root , custom kernel , ak2 & install them which is gonna take a long time since TWRp is super laggy.

And sometimes it still bootloops.

Please help me with this annoying lag :(

---------- Post added at 02:45 PM ---------- Previous post was at 02:42 PM ----------

Well the bootloader's unlocked and its not rooted but the device is fresh since I flashed it recently and factory data reset it. I got the 8.1 Dark rom and installed patch image and that showed up the bootanimation super slow and kept shutting down.
[Nexus 6P General] jimbomodder:
Ok so I'd say try flashing a custom kernel and then flash the patch and see.
[Nexus 6P General] Makarrim:
[MENTION=6576153]jimbomodder[/MENTION]

I just can't get this thing to go into the custom TWRP recovery, it just bootloops.

Can someone even creat a proper video tutorial on android 8.1 fix
[Nexus 6P General] :
Please somebody point me out how to get the phone out of bootloop. I have developer options already turned on. Hairdryer brought my phone to boot temporarily, but for a short time. I have 8.1.0, angler -03.85 Build OPM3 171019.013. The comments just make me confused, really don't know what I am doing. I just need the info where to find correct image files and step by step instructions. Would it be easier to go back to Nougat? Or go down to 4 cores? Really worried about bricking it for good :( Thanks
[Nexus 6P General] mdfarazb2:
Did you try the injector zip by Osm0sis?
[Nexus 6P General] DJesri13:
Should I update to Oreo?

I downgrading to by flashing N2G48B from the google developers page, then I flashed onto the phone "Boot.img from stock 48B, 7.1.2 firmware". If I update to oreo will it remove the boot file and put me back in the bootloop or am I good to update? Any help is appreciated.

Edit: I was dumb and just realized I should have installed TWRP, is there a way to unlock and lock the bootloader without resetting the phone? Or should I just skip TWRP, I heard there is something about it that may also get me stuck in a bootloop again. Also, I haven't seen any bad performance, is that just supposed to kick in once all my apps are reinstalled and running in the background and stuff, so far it seems to be working smoother than people from around the internet made me think it would.
[Nexus 6P General] nex-us:
My wife's Nexus is stuck in reboot. I have tried everything that was advised to try and unlock the phone but no success. I spent the whole day trying heating the phone even tried freezing once but nothing works.

Should I say the Nexus 6P is bricked and has an hardware issue?

Any help will be appreciated.
[Nexus 6P General] DJesri13:
How did you try to heat it? I heated mine for less than 4 minutes from about 1/2 to 3/4 inches away from the back of the phone between the finger print sensor and the glass bar thing ising a hair dryer on high. It only worked for a couple minutes but that was long enough to set up the phone, enable developer options, and make sure OEM unlocking is enabled.

I don't know if this helps but I kept the phone off while heating it. Also you don't need to heat the whole back of the phone, I watch a teardown video so I could picture exactly where I should be heating and where to focus it on.

Hopefully this helps
[Nexus 6P General] Volz04:
Nexus 6p in stuck in starting..

I have nexus 6p and i am facing problem related to starting.. my phone stuck on starting screen which showing only google logo. Pls suggest me. And i think OEM unlocking is also off. So i can't connect my phone to laptop system.
[Nexus 6P General] DJesri13:
I heated mine up for about 4 minutes (some people report needing up to 20 minutes, some maybe even more). I guess it depends on the hairdryer or method of heating. It ran long enough for me to allow OEM unlocking. It should be hot enough for you to be able to feel the pain if you touch any part of the phone's body. Have a small towel prepared if you are going to hold it. Then only part the needs heating is there spacing between the fingerprint sensor (imagine a horizontal line right above it) to the long glass camera cover thing.

Hopefully you find this helpful
[Nexus 6P General] aswinrulez:
Thanks this helped. FYI, mine was stuck at Google bootscreen when i flashed kernel. I skipped step 6 and everything works fine
[Nexus 6P General] Vermanucci:
Charge it and heat it more, one of the devices required a bit more heating after it managed to boot to android then shut off. When we used the heat gun it got super hot & eventually came and stayed up
[Nexus 6P General] burduli:
I'm a bit confused. I'm supposed to let it drain to boot it up, right? Why should I charge it?
[Nexus 6P General] XCnathan32:
Most likely a background or system process is dedicated to core 1, if I had to guess. The other 3 cores are still on, just not being utilized much. Fresh flashing the stock firmware, then flashing the mod, makes a bigger difference than you would think, also disabling animations, and enabling "Force GPU rendering" and "Disable HW overlays" in developer options helps a ton. Turning the screen resolution down to 1080p also helps, as well as flashing a custom ROM.

All of this may sound tedious to set up, but trust me, it will really pay of. When I first found this fix, I did the same optimizations as you + disabling animations, and it lagged a lot, but with the rest of tweaks I listed above, it works very smoothly, I uploaded a recording of how my device performs in the OP, check it out.
[Nexus 6P General] IM0001:
Thanks for this. I was able to build a 7.1.1 boot.img for my March Pure Nexus build that worked like a charm. Phone runs like a pig now, but my 6P JUST Bootlooped today and now I am just trying to get it back up enough to back up and then figure out what I want to do next. Sucks because I really love this phone.
[Nexus 6P General] ps000000:
Very nice.
[Nexus 6P General] jer0k:
Good to hear you got that working.

I still have no luck, I heated it up for 10 minutes till i got to the point where it actually showed me the animation, then it would quit after a while (did yours boot up completely?)

So after the animation stopped i went back and reflashed everything, but still no twrp option still boot loop for me.

I'll keep trying.
[Nexus 6P General] metallicant:
Pop

Plug it in and try to boot it. It should boot up after about 5 minutes or so. Once it boots up do not remove the plug or anything. Get into developers setting asap and enable debugging and allow to unlock bootloader.

Once you accomplish that follow everything step by step...

[Nexus 6P General] NexusGirl:
Hey man! Could you provide a similar solution for devices that are locked as well? I'm desperate to get my phone working again and nothing seems to work on this phone. Tried the Techno Bill way (from the Nexus forum).

Thanks in advance!
[Nexus 6P General] tjchuot287:
It couldnt see the file EX4_1_1_4Cores.zip

I tried it already but still. I couldnt access to sdcard to flash file EX4_1_1_4Cores.zip.
[Nexus 6P General] digweed4me:
did you fastboot the modded twrp from op or regular twrp?

you need to file this twrp which runs on 4core disabled same like kernel boot image

[Nexus 6P General] tjchuot287:
I did everything followed OP

Thank for quick reply, i followed OP exactly, the good thing is my phone is alive now but its a bit laggy.

i wonder that in Setting >> Encryption, it shows encrypted. I think that is the problem.

How can i turn off that encryption status anyway?
[Nexus 6P General] digweed4me:
the reason for lag is all four big cores are disabled only little 4 cores , thats yhe only way to stop the bootloop
[Nexus 6P General] tjchuot287:
Yep, i know, that the reason why i want to flash EX ...zip to improve my phone's performance a little.
[Nexus 6P General] Volz04:
Thanks bro.. but my device is locked..

So when i connect my device to laptop, my device is not showing in laptop.
[Nexus 6P General] Rafsxd:
Please, would you tell me what is "everything"? I've downloaded modded TWRP, flash it via bootloader mode, then I downloaded the N5X-6P_BLOD_Workaround_Injector_Addon-AK2-signed.zip, put into the phone, then flash it with TWRP. That's it. I don't wanna use a custom kernel or something like this. Or am I obliged to use it (custom kernel) for bootloader of death does not occur anymore?

---------- Post added at 06:02 PM ---------- Previous post was at 05:59 PM ----------

Heat it up, with a heatgun or hairdryer, the area between the camera glass and fingerprint sensor. It will turn on normaly. Then follow the steps to unlock your phone. Good luck.
[Nexus 6P General] jimbomodder:
All I did was flash the official Oreo boot IMG, then a custom one and the injector zip and for me at least it now works fine.
[Nexus 6P General] DJesri13:
Can someone please respond and help.

Also, is there a way to bypass my encryption. It isn't "default_password" nor is it my pin. I tried resetting the phone and then opening TWRP but it still wants the encryption password. I can't get TWRP access to install Super SU. Stupid question: Can I flash an .img of root or an encryption disabler? I really want to root.
[Nexus 6P General] Dathaeus:
Ok so after taking all the steps, on the final reboot, now it is stuck on the 4 animated circle screen that appears right after the Google logo when it is booting. Whether I am charging or not, it is stuck on this screen (where it is supposed to take a while) for over a few hours... and eventually the phone shuts off.

All the steps taken were flawless, as in I got no errors or "weirdness."

Suggestions? I'm just trying to get this to boot up so I can access my Ti-backup file.... I thought I had it in my Google drive but no, not since December for some reason, so I can start my new phone fully.

If I can access somehow my backup files without bootup, LMK but I would like to fix this for at least reselling this phone in "working condition."

BLOD happenend to my 6p again

Hey Guys,

My 6p had the BLOD almost 6 months ago, I followed the instructions and I was able to fix it however 15 days ago it happened again and I've tried to do the same as I did before but nothing is working, in fact now I can't go to recovery mode it only goes until the bootloader, any ideas? has anyone faced the same?

Thank you very much.
[Nexus 6P General] pharaohdk:
Quick question.

When OP writes: "Boot.img from stock 6.17, 8.0 firmware: Download | Mirror. This Image is the from the first official release of Android O"

Is that this version: 8.0.0 (OPR6.170623.013, Aug 2017, Not for TMO/USCC/Fi) or this version: 8.0.0 (OPR6.170623.019, Sep 2017) ??

Thanks in advance.
[Nexus 6P General] Ragav47:
Hi,

I have a nexus 6p with blod. I made it to work using the 4 core guidelines:

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

after that it was working fine for 2 month, currently running in twrp-3.2.1-0-fbe-4core-angler.img

Suddenly today the phone stuck at Google logo and the bootloops starts again. Now, neither the recovery nor the normal boot works.

I tried re-flashing the twrp-3.2.1-0-fbe-4core-angler.img again and tried lower version of twrp-3.1.1 with 4 core. Even that didn't work.

Also tried to download stock rom (7.1.2) and installed using cmd (flash-all) and patched N2G48B_4Cores.img (4 core Nougat image).

Nothing work and my phone is still in bootloop.

Does anyone faced this issue or know the solution?

Thanks in advance.
[Nexus 6P General] DJesri13:
Can someone please let me know if updating from 7.1.2 to Oreo will remove the custom boot img?
[Nexus 6P General] matszal:
which is the latest oreo factory image supported by 4 cores fix?

Hi guys,

I managed to fix my 6p couple days ago but heating it up did not work at all. I had to freeze it for 20 mins. It was the only method to boot up the phone in my case.

Anyways, I am trying to find out which is the most recent factory image that can be flashed and work using 4 cores? would 8.1.0 (OPM5.171019.019, Apr 2018) work with Boot.img from stock 6.17, 8.0.

Steps to install it: adb factory image -> boot.img -> twrp4cores -> 6pex4.1.2

Can someone please confirm before i attempt and waste full day fixing ;)

atm im using 7.1.2
[Nexus 6P General] Ragav47:
You can install any 8.1 ROM of 6P. Just install this zip in twrp after your 8.1 ROM and this zip will make ur ROM work with 4 cores.

https://basketbuild.com/filedl/devs...BLOD_Workaround_Injector_Addon-AK2-signed.zip

Note: Make sure you have twrp 3.2.1 (4cores) and the 8.1 vendor image before you flash 8.1 ROMs

Hello,

My phone has bootloop, bootloader is unlocked. I managed to get TWRP 3.1.1.-0, but from here I got stuck. I flashed "4cEX5_03.zip" but in vain.

In TWRP tells me that it fails to mount the system, when I give it a reboot tells me that "No os Installed! Are you sure you want to reboot?"

What to do. What do I need to install zip or img?

Please help, with steps for a beginner.

Thank you
[Nexus 6P General] Einwod:
Go and read the first posts. You have no OS installed, so your device is wiped. You need a ROM or factory images to continue.

That sounds like a permanent damage to other cluster of that snapdragon. Read somewhere that this is the only temperary solution. Since some cores are damaged already it was only matter of time.

Go up to and find post fro user Ragav47 - he gave me a link to 4cores signed zip. All I did was:

3. flashed Ragav47 file 5x_6p 4 cores signed.

After this i was on official latest oreo 8.1

Thanks for this guide, my 6p bootlooped from the nothing when i was watching facebook, and the data and cache folder was corrupted, for this

I format and create those partition in ext4 from modified recovery 3.1.1, and then flash the stock 7.1.2 rom(image-angler-n2g48b.zip), step by step, not with flash-all.bat, then reflash any of the modified kernels for this version 7.1.2, success.

But now the Phone is laggy and slow, a photo without hdr+ takes 30 seconds to process +-, a real ****, but at least works while buy another phone, many thanks for all.

The Phone life without bootloop was 2 years 3 months.(RIP)
[Nexus 6P General] matszal:
Just google search 6pEX4_1_2.zip, I believe at the moment your 6p works only on 1 maybe 1.5 cores. I had same issue after first fix. Changing to 6pEX4_1_2 helped a lot and can say now: the phone works very well and is still acceptable to use as a daily driver although i have this comofrt to use it as a spare device

Hello, you can install magistik on 6P with 4 core?

[Nexus 6P General] Ragav47:
Ya it worked in mine. But if you have warranty left, I strongly recommend you to give your phone to the service center and get this hardware issue fixed. Some phones get 18 months warranty, so if you have a doubt check in the nearest service center.

Also this 4 core fix is not a permanent solution. My 6p again went into bootloop last week (after 2 months of usage) and not working even after i tried many other boot images.

Hello, is there a guide anywhere to make your own boot.img.

I am still running purenexus_angler-7.1.1-20170113-OFFICIAL (vendor image N4F26J)

I saw a thread that made a script to make your own img and I want to try to make it 1 core or 4 cores because even after installing Twrp 4 core it did not work.

I just want to save my userdata before I give to the warranty so they can replace it.
[Nexus 6P General] jmaclean62:
I tried installing the April patch off of the patched pure Nexus rom after having the blod on my 6p. Afterwards it is pretty laggy, so I am trying to see if it is running on the patch. It's it way too tell if all the cores are working vs the 4 core patch? When I look using CpuZ app, it shows all 8 cores present and working. The lag is what has me wondering though. Does this patch show as just 4 cores with the CpuZ app?
[Nexus 6P General] DJesri13:
Does anyone know if a custom ROM I can install that works for 4 cores? I tried to do the Pure Nexus ROM but all the Google appls would crash even after a flashed a GApps zip. I can switch between Android 7.1.2 and 8.0.0 if I need to, I am currently running 8.0.
[Nexus 6P General] AndroidHtc101:
Yes the patch will show as just 4cores running with Cpuz. I would suggest a full wipe factory reset.

Then flash the Rom again from a fresh start.
[Nexus 6P General] alisj99:
to update, I have managed to boot into TWRP for 2~3 minutes after putting it in the freezer for ~20 minutes. obviously that did allow me to access the files or flash anything but I am sure I can boot into it and it's definitely a core issue. it could be that my damaged cluster is the BIG one not the SMALL.

any help is appreciated to enlighten me
[Nexus 6P General] jmaclean62:
So I wonder how that happened. I had TWRP BLOD patch installed and I had trouble with the April update, but it finally worked. Afterwards, I have no Bootloop. It seems a bit slow and laggy though compared to before the original Bootloop back in late March. Hmm... I wonder if the hardware and software together were giving the bootloop somehow.

I saw on the other link here that some guy claims to have fixed the bootloop permanently. It appears something like that has happened to mine. It could be the real deal or it could be that the hardware just hasn't completely failed and is working for time being.

It works well enough now. I will find out more when the May update comes out. I am going to just install the Factory Image and see how it goes. I'll report back when that all gets worked out.

[MENTION=5288606]XCnathan32[/MENTION] - Thank you very much for this guide + links. I was successful in getting my 6P up and running again in Pure Nexus and its running perfect. Thanks for all your work on this.
[Nexus 6P General] jmaclean62:
Update... I installed the May Factory Image that I got using Incognito Mode in Chrome due to the weird issue going on with the Image site. My phone went right into bootloop. In order to get things back up and running, I had to go into recovery and install TWRP and the patched injector. Everything is working fine, but it is only showing 4 cores on Cpu-Z now. Before the update, it showed all 8 cores working. It was kind of laggy though, so I am guessing that it was only running 4 cores, but Cpu-Z was being tricked somehow.

Regardless, it is working fine on just the 4 cores and it is good enough to keep me using it until something lots better comes along or it finally gives up and completely dies. Thanks for creating this opportunity for me.
