By crash you mean the screen becomes black and you need to hold power button to make it show google logo or it automatically restarts itself ?
[Nexus 6P General] W@r10ck:
Mine is just turning 3mos since i applied the fix. Hopefully it stays longer since i just had this phone for just a year.
[Nexus 6P General] leondestiny:
is this bootloop od on the 6p a random thing, happens out of nowhere to some users?

Can't find kernel zip on phone

I have TWRP and I have flashed the boot image, phone is working. But trying to flash the EX Kernel, but I can find the file in the recovery area. I select install, but not sure where to look. The file is in downloads when powered up. What am I doing wrong?
[Nexus 6P General] ricbaez:
The screen freezes, or goes black, then it starts to restart. Sometimes I am able to use the big cluster, other times no. I'm just sticking, to the 4 cores fix, really don't like the fact that I bought an octacore phone and can only use 4. I might send it to Huawei for RMA, I still have the limited warranty.

Make sure you're not in "Flash img" option in TWRP. You may have forgotten to click the button on the bottom that says "Flash zip"

Then it's a CPU soldiering issue. For a second I thought you battery is EOL and it's no longer able to supply the phone with proper power (and as a result when all cores are trying to run, phone turns off)
[Nexus 6P General] longlivandroid:
Did you get your 6P back? Have you experienced any issues with it since? My 6p died again after working for a few months using the 4cores solution.
[Nexus 6P General] btvolta:
Has anyone been able to get any of the recent oreo builds to boot up with the 4cores.img? I just tried on the most current Nitrogen build and it won't boot past the Nitrogen boot screen.
[Nexus 6P General] sully51:
Thank you thank you thank you for this! My phone went nuts today receiving a text and refused to boot. Tried everything else, then gave this my last effort and it worked! It will get me through until the Pixel 2 XL I ordered gets here on Thursday lol.
[Nexus 6P General] dodora3d:
i have worried problem ... i face bootloop from 6 months ago then yesterday i try open it and work well !! surprises

then update my software to oreo and work 2 days good then i got bootloop again !! Wtf

so now i need to download :

1- Boot.img from stock 6.17, 8.0 firmware

2-TWRP version 3.1.1

3-EX kernel version 5.03 that sit ?

any recommendation ?or explain what's happened to my phone works well again without did anything ?
[Nexus 6P General] inthedark22:
Got my second bootloop today, lasted 6 months with the first repair.
[Nexus 6P General] ricbaez:
Very strange... I decided to flash the stock boot.img (with 8 cores) and my device booted fine. Was boot looping before. It makes no sense...
[Nexus 6P General] fuadhdmini:
I tried to flash the Nov security patch using flash fire but always failed.

Can you share some brief tutorial how did you managed to flash Nov security patch?
[Nexus 6P General] maity-iman-2015:
Can you please let me know which month's boot.img you just loaded!

And previously which 4Core boot.img you were using on which Android build (7.12 or 8.0) and which months build?
[Nexus 6P General] fuadhdmini:
Which 4 cores image?
[Nexus 6P General] ricbaez:
I was on stock Android 8 September patch, I loaded the stock opr6.17 image. I was running the Oreo 4 core fix

---------- Post added at 04:07 PM ---------- Previous post was at 04:05 PM ----------

The Oreo image, I'm running November patch with the fix, works well. However OTA didn't work for mez probably cuz I was rooted, so I flashed the factory image then the boot image
[Nexus 6P General] AddisG:
Nice! Mine died a week ago. Now I got myself a brand new pixel XL. Loving this thing!
[Nexus 6P General] Elvik.W:
Many thanks to you. :good::cool::cool:

My phone suffered the issue on the weekend, and I just flashed your latest 8.0 image and it was working until now.

Just one question, my company's app (mobile iron) requires data encryption,and I failed to do encryption after flashing the image. Is it anyway I can do to make my data encrypted?
[Nexus 6P General] dodora3d:
any help guys ?
[Nexus 6P General] ricbaez:
I would like to add, that it might be possible to run 8 cores. Just underclock the big cluster to 1.2 GHz using ex kernel, just keep the modified boot image on your phone so you can flash it on the go (just in case). So far no issues with underclocked big cores

---------- Post added at 05:23 PM ---------- Previous post was at 05:21 PM ----------

Yes that should be it. From bootloader flash modified recovery, go to recovery, Flash the ROM (skip if you want) then flash the modified boot.img, then finally flash ex kernel mod.

As to why your phone did that, no idea. The issue is bad soldering though.
[Nexus 6P General] dodora3d:
thank man for your help ..

i will try this method tomorrow ..

which way better 8 corse and sit 1.2 or 4 cores ? or both same performance ?
[Nexus 6P General] ricbaez:
It really depends. If your problem is pretty bad you may have to use 4 cores. Try the 8 cores and if not stick to 4
[Nexus 6P General] aoaleman:
I could never get them to boot with custom ROMs. The only one was AICP Oreo and the last build I tried was 10/22.
[Nexus 6P General] Snowers96:
I have another question, if a lot of people have the 4 cores fix running already in their phones, why they suffer bootloop again?
[Nexus 6P General] dodora3d:
guys i unlocked my phone then from bootloader flash modified recovery and flash modified Boot.img from stock 6.17

but i stuck when go to recovery from phone just google then restart again and again so i can't go to recovery so i can't flash EX kernel..

so what should i do ?
[Nexus 6P General] ricbaez:
If you flashed the modified recovery from this post, you should be able to boot into recovery are you sure you did it correctly
[Nexus 6P General] dodora3d:
yes man i think i did it right
[Nexus 6P General] fuadhdmini:
Thanks. I'm running the one with November security patch now.

---------- Post added at 03:52 PM ---------- Previous post was at 03:48 PM ----------

Anyone has the stock boot image for Nov security patch? Gonna try the underclocking big cluster to 1.2Ghz.

Update:

I extracted the boot image from factory image of Nov. Tried underclocking big cluster. Not booting. Bootloop atau Google logo
[Nexus 6P General] btvolta:
The fix has worked well on my phone for stock Oreo, but none of the Oreo custom roms will boot past the boot animation. ( On nougat, however, I enjoyed multiple custom roms). I am very appreciative as this fix bought me a little more time with my beloved 6p. I recently purchased the op 5, but just sold it the other day. Since, I have ordered the new pixel 2, and google is giving $155 for trade on the 6p, as long as the screen turns on, and the glass isn't cracked. I have fully set it back to stock, so I don't expect any problems getting the full trade in value.
[Nexus 6P General] byelyasa:
Thanks to you, my phone is running!

I have been using Oreo 4 Cores firmware.

If i install new system updates, can a bootloop problem occur again?
[Nexus 6P General] zhangla:
Your phone will certainly go into bootloop again... Mine did. it's just matter of time, does not matter if you install updates or not. It's SoC soldering issue, hardware issue.
[Nexus 6P General] maity-iman-2015:
Hi all, I have a good news. Finally, I'm able to boot Android 8.1 beta on my Nexus 6p. All thanks to MaowDroid (YouTube: https://www.youtube.com/channel/UCUWBye5gZ6ffAv458I6hKTg)

This is an awesome channel, you should check it out.

Steps:

1. Download Nexus 6p Android 8.1 img from https://developer.android.com/preview/download.html

2. Download 4Core boot img (created by MaowDroid) from: https://androidfilehost.com/?fid=889964283620766837

3. go into fastboot mode (adb reboot bootloader)

4. flash bootloader.img (adb falsh bootloader bootloader-angler-angler-03.75.img)

5. reboot to bootloader (fastboot reboot bootloader)

6. fash 4 Core boot img (fastboot flash boot 4core-patched-boot-angler-opp5.170921.005.img)

7. fash vendor img (fastboot flash vendor vendor.img)

8. flash radio img (fastboot flash radio radio-angler-angler-03.85.img)

9. flash system img (fastboot flash system system.img) * I want to keep old twrp recovery, so didn't flash recovery.img

10. fastboot reboot (it will take few mints)

* I didn't root new Android 8.1, but flashing SuperSU.zip should work

** didn't flash any custom kernel, please try and let me know
[Nexus 6P General] W@r10ck:
Great news indeed. Cant wait to test it out :)
[Nexus 6P General] ricbaez:
Any one getting extreme lag? Sometimes my ui will lag super hard, and it will soft reboot. Any thing I can do?
[Nexus 6P General] maximusmullivan:
So my old 6P was bootlooping. This morning I flashed the November factory image and then your Oreo4Cores.img. Phone is working once again. Thanks, saved me from buying a backup phone
[Nexus 6P General] squabbi:
Thanks for posting it up here with instructions! :D

As for custom kernels, depending on how they install themselves, if they patch the stock boot image, then it should be OK, but if it replaces the existing boot image we'll need to modify that too I believe. :)
[Nexus 6P General] TheToto318:
Hi guys ,

I have try the moded boot.img for Android 8.1 and its working !

And its very pleasant to use !

Screenshots :
[Nexus 6P General] Mihaillo:
Just a small correction in task no. 4 it should be "fastboot flash bootloader bootloader-angler-angler-03.75.img" without quotes.
[Nexus 6P General] Einwod:
Still wrong. It should be: fastboot flash bootloader bootloader-angler-angler-03.75.img

You'll also see from my signature that the bootloader has been updated to a higher version also. 03.77 for Oreo 8.0.
[Nexus 6P General] Mihaillo:
You are right, my bad.

Yes, you can use newer version of bootloader.

What kernel to use? I tried using Ex kernel 5.03 and it doesn't work on 8.1 oreo.
[Nexus 6P General] Einwod:
I was on the EX modified kernel but only on stock Oreo 8.0. Last week I was using instagram and suddenly it froze, the phone completely died and would not, under any conditions restart. It would show the charging symbol when on mains charger and gave the USB tone when attached to the computer, but no ADB or fastboot would work. Luckily my partner was going to Germany last week also so she took it back to the shop where I bought it and it is still under guarantee, so we'll see what happens. It had the motherboard replaced when it was 3 months old. I wait to see what their emails say. They already said that a battery is only guaranteed for 1 year if not removable.

Still no update on this using a bugged version of TWRP?

The modified recovery prompts for a password on encrypted devices, but nothing works. It's a known issue with TWRP... I would like to see how it was modified to only use 4 cores so i can try a different version.

[Nexus 6P General] bballs91:
Yeah im having the same issue. About 1x per day the UI gets completely stuck (seems pretty random too) and I must reboot.

Definitely still a lot better than having an expensive paperweight.. I'm thinking about trying a different ROM, maybe that'll clear this up.
[Nexus 6P General] ricbaez:
Found a fix. Enable force gpu for 2d rendering and disable HW overlays in Dev options
[Nexus 6P General] bballs91:
Thanks for the tip. I've enabled those two settings now, fingers crossed!
[Nexus 6P General] fuadhdmini:
Seems like the modified boot image for 8.1 is like the earlier boot image created by xcnathab32, the boot image not efficiently utilize all the functional cores.

Thus the lag and reboot.
[Nexus 6P General] W@r10ck:
That's expected. Our device would never run 8cores else you'll have the boot loop experience again. Mine is running battery smooth just like the previous 8.0
[Nexus 6P General] SKArabaeus:
So I got hit by BLOD as well. heatgun worked for me to get the phone up and flash boot img - I took "4Core boot img (created by MaowDroid)" from this comment: https://xdaforums.com/showpost.php?p=74543375&postcount=1825 because I was on 8.1 beta (via OTA). I flashed all files from the 8.1 system images to be safe (+4core boot.img) - I can access twrp recovery fine (went there straight after flashing and wiped cache/dalvik, but my phone is stuck in the color-circle bootanimation and doesn't seem to get out of there - how long does booting take after flashing? what can I do to get back into android without losing my data?
[Nexus 6P General] fuadhdmini:
Am not talking about not having 8 cores.

Most probably you didn't follow this thread from the beginning. The early fix even though able to boot Nexus 6p but the utilisation of the 4 small cluster cores are not efficient, thus affected performance greatly.

Then xcnathan32 managed to improve it's 4 core mod to better 4 cores.

---------- Post added at 11:44 PM ---------- Previous post was at 11:36 PM ----------

I was talking about this earlier. Earlier boot image was like this, then xcnathan32 managed to further improve the core utilization of the 4 cores.

The current boot image of 8.1 is apparently like this
[Nexus 6P General] W@r10ck:
My bad, i get what you mean. I wonder why it happens to random devices.

---------- Post added at 08:09 AM ---------- Previous post was at 08:08 AM ----------

Mine took awhile for the first boot. Maybe around 5mins. It shouldn't take more than 10.
[Nexus 6P General] SKArabaeus:
Damn :-/ I waited way longer than 5 minutes. I even re-flashed 8.0 (complete factory image - then twrp 4 cores, boot 4 cores and side loaded elemental 4c_5_3 in twrp to be sure. now I'm looking at the circles again since round about 30 minutes.

Any idea what to do?
[Nexus 6P General] LittleOnionThatCould:
Mine was stuck at the circles for an hour so I tried this:

1. Re-flashed stock Oreo

2. WITHOUT reboot, flash the Oreo4Cores boot image.

Booted up in about 1 minute after that and has been working perfectly ever since
[Nexus 6P General] FlyOnTheWall43:
Hello Everybody,

I currently have this BLOD on my 6P... here's what I've tried:

I tried the steps in the OP and the steps sunnyhj detailed in post #658, but after I flash the 4 core boot img and the 4 core twrp image and I try to boot into TWRP, my phone continues to boot loop.

Am I stuck short of opening my phone and re-soldering my SoC? (not that I actually plan on trying that)

Any help/info would be greatly appreciated.
[Nexus 6P General] maximusmullivan:
Flash a factory image then flash the boot image. Don't boot the phone until you've flashed both
[Nexus 6P General] FlyOnTheWall43:
Just did this and got the same result... doesn't get past the Google screen before rebooting. Thank you for your suggestion.
[Nexus 6P General] v12xke:
Will re-locking the bootloader re-write/over-write the 4 core boot.img? I'd like to return my phone to Google with a locked bootloader but not if is going to render the device unbootable. Phone works fine with the modified boot.img, but will not boot with a stock boot.img.
[Nexus 6P General] SKArabaeus:
I finally got it working last night (needed to do a factory reset...) - flashed Oreo, then without booting the modified boot.img and my phone worked almost the complete day today. unfortunately an hour ago it turned off and I had the same problem again - only heatgun helped to get it running. then after a couple of minutes with display off it happened again. eagerly waiting for my pixel 2 xl - but what can I do in the meantime? why is this happening, even though the modified boot.img is flashed (CPU-Z confirms that core 4-7 are all stopped). I just installed EX kernel and hope this helps...
[Nexus 6P General] SlimSnoopOS:
If you are returning the phone to Google, flash the factory image and leave it bootlooping. It's not your fault the phone is bootlooping on eight cores.
[Nexus 6P General] v12xke:
My phone is way out of warranty. I was hoping to use it in their trade in program when I buy a 2XL. It has to be factory reset and be able to boot up. There is not a scratch on it. Google uses a 3rd party Company (Apto) to recycle the device. If re-locking the bootloader over-writes the boot partition, I won't be able to get back in and unlock it.
[Nexus 6P General] brainlessnobrainer:
thanks for the fix, got my nexus working again. whats weird tho is that i cant seem to be able to run any other rom except pure nexus - i wanted to try lineage 15 (oreo) but found out that it was just stuck indefinitely while booting up (not bootlooping tho). after a little bit of fiddling around with ressurection remix, cyanogen, lineage and all of kernels and boot images in first post i found i wasnt able to boot the damn phone with any other distro except pure nexus with fixed pure nexus boot image(which is wrong apparently but when i install 48B or C i get infinite boot again). interesting.
[Nexus 6P General] btvolta:
I've been able to boot any nougat rom, but on Oreo, only stock and Superex will work.
[Nexus 6P General] mohdfahad47:
I have a question, my phone bootlooped like just 3 hours ago, i was on some November build of dark Rom (nougat) and as far as I can recall I had a custom kernel installed, it was kerinvore or something . Since I had a custom kernel, which kernel do you suggest I should install? I actually reverted to nougat from Oreo to check out xposed ( silly me) I already have my boot loader and radios updated. Is there a way I could go to Oreo without losing my data?
[Nexus 6P General] efx456:
Can I lock the bootloader after flashing the Oreo4cores.img so I can trade the phone in?
[Nexus 6P General] javitomen:
My phone shutdown at 50% then when I charge it again and turn on battery level so at 50% again and I only charge the phone for 1 minute. Any info what's it's happening?, Or do you think I need to change the battery or something with use 8.1, because I think I should have a lot of better performance because I only use 4core.

Hair dryer to the back worked for me. Aim about middle. Just heat it until you see the standard boot circles. Mine shut off immediately after that, I assume due to the heat. Started back up normally after it cooled down.

Hello guys, I need your suggestion and advice.My Nexus 6p seems to shutdown when ever the battery reaches somewhere between 40% to 15%.When I try switching it back on it shows hardly 2% battery and immediately shutdown once again.I have tried using custom roms but the issue still remains. I see that this thread for bootloop of death fix that will disable 4 cores etc etc but do I really have a bootloop issue ? Please confirm if my issue is related to bootloop issue,so that I can proceed with the fixing guide thats given here.

If its not a bootloop issue then what is the issue ?and is there any fix for it ? If yes please help me with the guide/link

[Nexus 6P General] v12xke:
Replace your battery. What you describe is consistent with a bad battery, not BLOD. Research XDA for a recent and reputable source of a quality replacement. Beware Ebay / Amazon, etc. are full of bad batteries. Lastly if you do the work yourself (there are tons of YouTube videos) do NOT fully close up (seal) your device until you have tested the replacement battery. Low amperage charging, excessive heat, and not reaching 100% are signs of a bad replacement.

I had the same premature shutdown issue for the past 6 months or so...and then 3 days ago my phone went into BLOD. I tried all the available fixes there are in existence and nothing worked for me, now my phone's just a paperweight...guess I'm a bit too unlucky. My advice, change the battery asap and trade the phone before it's too late.
[Nexus 6P General] Eddie_Brock:
There is no solution. I've been posting in this thread about the patched version of TWRP being bugged, but no one seems to acknowledge it. I've looked into it, and it was one particular version of TWRP that had this issue. Formatting data does not help, Factory Reset does not help.

The only solution, as I see it, is to apply the "4 core patch" to a newer version.
[Nexus 6P General] Ather:
2nd DP is out, do you have a modded kernel with 4core patch for it?
[Nexus 6P General] fishgoon:
You Rock! - low battery trick worked

I was running oreo and received bootloop yesterday with locked bootloader. I was able to boot the system briefly to unlock the bootloader by draining the battery to below 5% which was suggested in a related LG thread. Aparently at low battery levels the processor self restricts use of the troublesome 2.0Ghz cores. Anyone who is unwilling to try the freezing or baking methods should give it a try. I now have the patched kernel installed and am back up and running. There is a slight bit of lag compared to previous performance but it's hardly noticeable.

Thanks for saving my phone, I thought it was a gonner!!!
