I used 4corefix by meowmix and it works absolutely fine. Why not use that instead
[Nexus 6P General] squabbi:
Yes sorry, flash/install I use interchangeably for TWRP, but I only use 'flashing' when it comes to using fastboot.

Not sure what's going on, do you have access to the /data partition? As it should only need /tmp/ and access to the ramdisk.

If you continue to experience issues, you may need to patch your own boot image and flash that via fastboot, instead of using the BLOD workaround ZIP.
[Nexus 6P General] squabbi:
Any reason you wanted to flash the stock (full?) OTA via TWRP instead of using the factory images? I'd give using the factory images using fastboot a go and then re-apply the boot image patch. :)
[Nexus 6P General] squabbi:
What version of Android were you on before?
[Nexus 6P General] rcs4787:
Was your phone working with a previous patched boot image before updating to the April update?[/QUOTE]

No, I was on 7.1.2(48C) August 2017 when BLOD happened. I somehow cleaned OP system and phone would only update to TWRP 3.2.1 4Core. I decided to try and push everything to the latest build, was that a mistake?
[Nexus 6P General] rcs4787:
[MENTION=4752144]squabbi[/MENTION]

I was able to use this process to revive phone back to original 7.1.2 4Core image. Now going forward, will this same process update me to Oreo 8.1 4Core? Thanks a million man!
[Nexus 6P General] squabbi:
I don't think updating all the way from 7.1.2 to 8.1.0 would cause any issues. However, the upgrade/first boot may have taken a while.

You should be able to use the factory images to update (flash them via fastboot, details in the first post) and then flash the patched boot image and optionally the patch version of TWRP if you're inclined to have it installed, or if you are choosing to use the BLOD workaround zip. :)

What is too long for the phone to boot up after updating? I have been on rainbow Android boot screen for 30mins?
[Nexus 6P General] Dodorex:
For anyone interested just did an antutu benchmark after applying the BLOD fix on my N6P Lineage 15.1 rom, I got a score of 79163 which is not bad I think for having big core disabled. Also I don't really feel the phone sluggish. what is the average antutu score of a nexus 6p without BLOD fix?
[Nexus 6P General] ricbaez:
About the same around 80000, Antutu is mainly GPU benchmark, what will really show the sluggishness is the geekbench
[Nexus 6P General] jmaclean62:
I kept toying with it and it finally fully booted into the April patch of 8.1. Very weird experience. I'm glad it is working again, but I really have no idea what happened. It seems solid, but I have no idea why it went into bootloop randomly while walking around town last week.

It is now running the April patch without the 4 cores patch or TWRP. Totally stock now with bootloader unlocked and debugging running just in case.

:)

hi [MENTION=4752144]squabbi[/MENTION]

Thank you for the reply, I know I am really worried about the photos and that is the only thing I want to recover at this stage. I do have lots of important photos in it and i just cant imagine loosing them. What I posted before tells you that my boot loader is locked ? or do you think I might have some luck there ? Posting that section again below as i am trying to find my luck here.

BL:angler-03.79

baseband: angler -03.85

product/Variant : ANGLER-ROW-VN1

serial number : bla bla

CPU: MSM8994 0x20001

eMMC : 64GB Samsung

DRAM : 3072MB HYNIX LPDDR4

Console : NULL

Battery : OK

Device is Locked

Qfuse Status : ENABLED

Off-mode-charge : ENABLED

Download mode: DISABLED

Connet USB Data Cable

My bad I never had the photos backed up to the cloud (google photos) I was meaning to take an offline back up of it, but now its too late.

As per your previous reply, How can I boot to recovery and use ADB to pull the DCIM folder ? Is this difficult to do ?

Any help would be appreciated

Cheers

[Nexus 6P General] knaxx1:
Select recovery mode from the bootloader. After in recovery use adb pull command on /sdcard/DCIM/ to your local drive. I think you might also be able to mount the full /sdcard/ in stock recovery as well. That way you can pull everything.

If you get bootloop while trying to get into recovery you can't do anything besides try and heat up/cool down the phone to get into system and unlock bootloader.

I tried flashing tons of different images in the other thread and can't get into recovery or system on any version of android. My phone always just bootloops no matter what I try.
[Nexus 6P General] guyderam:
Which partition do i flash the workaround zip to?
[Nexus 6P General] SlimSnoopOS:
The 5x/6P injector zip provided by Osmosis? You install it using TWRP. Just click install, do not click install image.
[Nexus 6P General] cynsx:
This thread is great. Thank you, squabbi. I followed your instructions in Post 2 and my Nexus 6P recovered.

But I do not need the root function. Is it safe to skip step 13 (installation of Magisk) when I flash any update?

Another question, If i relock the bootloader after applying the BLOD workaround zip, can the phone bootup normally?
[Nexus 6P General] cybugz:
Hi guys..

How do i know if my 6p uses 4 cores only? Base on the blod fix.. the phone will work with 4 cores only.?
[Nexus 6P General] AndroidHtc101:
Run CPU-z and you should see the big cores offline.

https://play.google.com/store/apps/details?id=com.cpuid.cpu_z
[Nexus 6P General] cybugz:
where is the big cores here..? All of the 7 cpuz are online.
[Nexus 6P General] blackhawk85:
Thanks [MENTION=9079940]knaxx1[/MENTION] , I think mine bootloops when I try to go to recovery mode. It basically does the same thing when I do a normal start or a recovery mode start. I can keep it steady at the screen where it lets me select "recovery mode", "start" , "clear cache" etc. Is this going to help ? Is there a way to boot these phones from an external device ? as in a PC ?

If I heat/cool and manage to boot it to recovery mode is it ok for me to unlock the boot loader ? I hope this is not going to wipe anything if I do that ?

Thanks and Regards

[Nexus 6P General] Kasia:
I try to recover my sister Nexus 6P for several day.

The last thing that make it works is here.

Download Android Oreo (8.1) from google

https://dl.google.com/dl/android/aosp/angler-opm5.171019.019-factory-e6191337.zip

Extract this angler-opm5.171019.019-factory-e6191337.zip

Connect the phone and set the phone in to Bootloader ,ode.

Then, double click "flash-all.bat"

Download this TWRP recovery

https://androidfilehost.com/?fid=745849072291698840

Extract it into the adb folder.

In bootloader mode

C:\adb>fastboot flash recovery twrp-3.2.1-0-angler-4core.img

C:\adb>adb reboot-bootloader

Boot phone into twrp recovery.

Go to Wipe => Advanced Wipe ==> select "Davvil/ART Cache" and "Cache". Then, Swipe to Wipe

Then, reboot recovery.

Download 4core-patch-boot-angler-opm3.171019.013.img from here.

https://www.androidfilehost.com/?fid=673791459329070783

Now, copy 4core-patch-boot-angler-opm3.171019.013.img into the phone.

Goto Install and look into the folder you put the file in. Select install image.

Select the file, select Boot and swipeto confirm Flash.

Now, Reboot System.

Actually, it works on this firmware also (angler-opm3.171019.013-factory-3204625a.zip). However, one it was working, I tried to update the security path but it wouldn;t work. The, I decided to flash it to the latest firmware, but it boot loops again. So, I had to do it over with the latest firmware intact.
[Nexus 6P General] JaneDoe444:
Thank you so very much, it worked. It took me over a day to wrap my head around all the complicated details, programming etc and I watched an hour of related video tutorials.... but it worked! Just a side note, steps 13 & 14 do not require sideload adb (it appeared the way to go) but just hit Install, it'll say it flashes those files.

The only thing I'm wondering, what happens when I make system updates? Will it reverse all of it or does TWRP keep it at bay?
[Nexus 6P General] Kasia:
I did try it. It wouldn't install the update.
[Nexus 6P General] JaneDoe444:
Do you mean the original factory images or the last two steps?

Dear Kasia,

How far did you get in the steps?

After step 12, rebooting into recovery and effectively activating TWRP, your device should pop up fresh with access to it's storage. This allows you to drag & drop Magisk and BLOD zips straight to the device. Than head to TWRP Install.

Btw, I am on Windows which makes a difference. I have seen people being able to "flash" within the command prompt but that didn't work for me.
[Nexus 6P General] Kasia:
I am also on Windows 10. I use the the adb tools from the link in the Google website recommended.

http://developer.android.com/tools/help/adb.html

Using the power button and volume-up to get into the bootloader. Then, I did what I said in my previous post.

BTW, I put all the links to the files I used in the post.
[Nexus 6P General] JaneDoe444:
Okay

1. Only use the google download to get the IMG files, ignore what google writes otherwise. Also, do not use Googles flash-all.bat, do every flash by itself in command prompt, preferably after loading the original files from your download into the same folder as your adb.

2. Do not Wipe anything once you are in recovery within TWRP,

3. Do not use the 4Core image, BLOD Workaround ZIP works far better. Magisk keeps the kernel file in the right shape while BLOD workaround zip keeps the CPUs usage to 1-3 (which is the main problem).

But you used an old 4Cores.img that does not address the base kernel file (or something along the lines. The two zip files were created for people like you and me....so we don't have to into the coding part.

Your steps are a mixture of three very different posts I read, you can't just mix and match. If you stick to the original steps in this post you can make it work.

Stay with the original tutorial!
[Nexus 6P General] Kasia:
I did all those step before, but did not work for me. It was just keep booting, cannot even go to the recovery. But the last thing I tried works.
[Nexus 6P General] JaneDoe444:
Dear Kasia,

Is it currently working? I'm getting mixed messages here as it appears it still gets back into bootloop.

Try reviving first. That's the short one without factory images.

Access your device storage when in Recovery TWRP by any means that work for you, than only flash (Install on TWRP) Blood Workaround ZIP.

Yes, it's a bit repetitive but there's a good reason for that.

Followed by updating with the long updating guide.

In this case, follow the steps exactly by flashing each IMG with command prompt do NOT USE Googles Flash-All.BAT, once in recovery with TWRP, send Magisk and BLOD Workaround ZIP onto your device, it should have prompted access to its device storage once you get to TWRP. It is vital that you flash Magisk (through Install on TWRP) before flashing Blood Workaround (though Install on TWRP) without rebooting in between. Now reboot.

It is surprising how important it is to follow each step carefully if you are not familiar with programing.

[MENTION=966941]Kasia[/MENTION] This is very useful for you, it explains it a little better. If BLOD workaround doesn't work you can watch the video tutorial posted in this thread to patch your own. I tried it myself but BLOD worked better for me.

If you can get to TWRP Recovery mode on your phone you should be on the right path.
[Nexus 6P General] Kasia:
Yes, It is working now with the procedures that I said in my first post in this topic.
[Nexus 6P General] cybugz:
any idea guys..? I tried to use this method to restore my 6p.
[Nexus 6P General] jassun16:
I have been trying to get out of the bootloop issues since August of 2017 and nothing seems to work. With the guides provided I couldn't even boot into recovery. I tried whatever method possible but not luck. My phone doesn't boot into recovery. It just bootloops. Any help is greatly appreciated ! [MENTION=4752144]squabbi[/MENTION]
[Nexus 6P General] alisj99:
your issue could be something else rather than the 4cores.

I'm just a day into this but I don't know what else should I do if the flashd TWRP doesn't work.
[Nexus 6P General] jassun16:
Alright thank you for your reply!:D
[Nexus 6P General] prateekgulati:
Hey,

I tried to unlock my nexus 6P and flash a custom rom but ended up with a full wipe and bootloop.

Though this thread has helped a lot of people, the steps seem confusing to me

This is my first time. Can somebody explain me which files here need to be modified and which not.

I tried modifying factory image and got this error on running repacking.bat

Building image . . .

Using format: AOSP

Signing new image . . .

Using signature: AVB boot

Error!

Press any key to continue . . .

My TWRP for 4 cores seem to work fine. How can I push a modified image zip and install it from twrp?
[Nexus 6P General] sean222:
Thanked and rated 5 stars. This thread saved my a$$. I was in SUCH denial that my other cores didn't die. Wiped and flashed about 15+ times hoping I would magically boot up but no :(

Followed this thread and I'm up and running! Thanks so much.

Sucks knowing that only 4 cores are running :( I hope this is at least saving battery!!!! :D
[Nexus 6P General] markolefas:
Newbie here. Thank you very much for this topic. Since all my friends' 6Ps went into bootloop, I decided to use the 4 core solution with the 8.1 android just for precaution reasons. It worked for me (for 2 days). Today when I answered a call the phone went dead. Rebooting stopped in the "android" logo and since then the phone does not seem to have any battery power at all. Charging fails. Cannot go to the bootloader. The pc can only recognize it as Qualcom device in COM 3. Is it system or a battery failure problem. Is there a way I can restore it? Thank you!
[Nexus 6P General] cybugz:
How to view if my 6p is using 4 core?
[Nexus 6P General] AndroidHtc101:
From your above screenshot, seems to be all 8 cores are online and working.
[Nexus 6P General] AndroidHtc101:
Here's a screenshot when you have modified your nexus 6p to use 4cores.
[Nexus 6P General] cybugz:
Okay so this is to confirm to all users of nexus 6p. after the blod workaround, only 4 cores are working. Then you can update the official ota update and there you are.. 8 core are now online as you've seen on my screenshot.
[Nexus 6P General] oussamalabbize:
I tried the solution since 2 weeks, I didn't have any issue with my phone.
[Nexus 6P General] cybugz:
I'm very sure. You didn't follow properly the procedure.

my 6p is revived by this workaround.
[Nexus 6P General] bfishman:
Hey folks. Interesting development with my bootloping 6p -- after installing a new battery, I'm now able to access STOCK recovery mode (could not do so prior). Phone still bootloops but I'm hoping to be able to back-up some files using recovery.

USB debugging is enabled.

OEM Unlock is enabled BUT the bootloader is LOCKED.

My question is: is there a way I can backup my data from the stock recovery? Frankly i'm only interested in my sms logs. I've read about people sideloading TWRP but am not sure if that would help me. Fairly new to messing with adb etc. Any help would be appreciated (just point me in the right direction, I am competent, just new).

TLDR; bootlooping 6p, finally have access to stock recovery, OEM unlocking enabled but bootloader is LOCKED, is there anything I can do to back-up my user data before fastboot unlocking?

Thanks!

EDIT: could I sideload a stock android update with the 4-core fix baked in??

EDIT: damn signatures
[Nexus 6P General] mbarry55:
Man this thread just saved me $200 for a new phone and got me up and running again. Haven't read through the whole thing yet but where do I go from here? Should I look to replace this phone or how close to deaths door is it?
[Nexus 6P General] pnoland89:
Edit: I thought this worked for me, but I'm once again stuck at the jumping balls screen. Has anyone else had a similar problem where they escape the bootloop but get stuck at this animation?
[Nexus 6P General] SlimSnoopOS:
This is merely a temporary fix. Plenty of people have had their phone bootloop even with the 4 core fix successfully applied. I recommend you at least continue searching for a new phone.
[Nexus 6P General] Rafsxd:
And I'm pretty sure that I followed every single step correctly. The procedment too simple that there is not room for mistakes. Just download and flash things.
[Nexus 6P General] oussamalabbize:
Did anyone tried a 6 or 7 cores mode ?
[Nexus 6P General] dieGeist:
Followed the steps and flashed a stock image from Google's page. Not sure if it was even the right one since there are so many but it worked....

It's kind of slow, I'm thinking of going to custom kernel with encryption disabled, etc... Would I need to reformat for this?

I'm not going to use a custom rom just kernel. Just not sure if I would get the right one.
[Nexus 6P General] rbouza1:
Came here to say my 6p just blod , this fixed it. Thanks
[Nexus 6P General] irvinj:
Can anybody attest to this guy's claim? He said his Nexus 6P was revived by the workaround and then after OTA update, 8 cores were working again. He claims he'd done this to 5 Nexus 6Ps. Seems to me he doesn't really know what BLOD is and what happened to his phone (or 5 phones as he so boastfully affirms) was something different (a different/simple kind of bootloop). Any thoughts?
[Nexus 6P General] AndroidHtc101:
The way BLOD happens is the SOC on the 4 big cores fails( so you can't boot past the android logo screen or get in recovery)

So disabling the 4 big cores android can boot on the small cores. This is only a temporary solution however.

I've been running with most animations off in developer options. , GlassCannon kernel I flashed with Ex kernel manager.

In fact battery life is miles better with 4cores. Ok we don't get as much speed on 4cores but a least we can still use our phones and recover our data.

If you just use your phone for email, chat, YouTube etc you don't need 8 cores imo on android. 4 cores is sufficient.

Your also notice on a normal non BLOD nexus the big cores will shut down on apps that don't require them to save heat.

We can also update to the latest security updates with the workaround Zip:)
[Nexus 6P General] irvinj:
The thing is, he says all 8 cores of his Nexus 6P's CPU are working again after applying the BLOD fix and doing an OTA update. He posted this screenshot:
[Nexus 6P General] 18yusuf:
I've fixed my 6P with this 4 cores patch about 5 months ago but my 6P doesn't boot up anymore. It boots up to bootloader but neither recovery nor the system boots up anymore.

I decided to got my 6P's CPU reballed. I ordered this from AliExpress and found a repair shop to do reballing. Currently waiting for that stencil to arrive.

Reballing might not be the exact solution for long term, but I'll give it a try. It'll cost me about 50$ in total. Will let you guys know if it works. You can find a reballing video for Iphone 6 to understand what is reballing, and the picture of stencil below.

I told you already that it is working dude. you should follow the procedure given for blod workaround
[Nexus 6P General] Tigran_:
Guys good day,

Will share with you my findings and have some questions also:

1) had BLOD on my 6p 64gb.

2) was running for some time under low battery mode. (this way I could enter settings and do what I want)

3) Flashed with stock firware for Android 7.1.2 (N2G48B)

4) Flashed TWRP_4core for replacing stock recovery mode

Flashed boot patched N2G48B_4Cores.img

5) While not having encryption - rebooted into recovery mode (twrp) and installed EX_4core (for cpu boost).

6) under EX set for 4 low CORES 1709Mhz (instead of 1555Mhz stock)

7) rebooted to system

8) BLOD disappeared.

All works fine (except lower performance but quite acceptable for my kind of phone usage now, and unavailabiity to update Android to later versions - see below)

What I've noticed during my experiments:

1) If you skip flashing TWRP, nothing will help avoid BLOD. Can't get dependency - but this is how it worked in my case. Having flashed TWRP_4core (not only patched boot image itself) is the only way to go beyond Google logo in my case.

2) for me patched boot image for Android 8.x.x can't work for some reason. I tried to install different Oreo firmware editions and pathced boot images for them (angler-opm5.171019.019-factory-e6191337.zip , angler-opm3.171019.013-factory-3204625a.zip ...) and followed same procedure I followed for 7.1.2 but with no luck. Sometimes I go beyond Google logo and see "dancing balls", but then phone goes to BLOD again.

3) I saw no luck with patched boot images (did patching and repacking myself) for 7.1.2 that contained changes in "fstab.angler; init.angler.rc". The total difference for me did image that contained changes in " boot.img-cmdline" file in this way: ...

androidboot.hardware=angler androidboot.console=ttyHSL0 msm_rtb.filter=0x37 ehci-hcd.park=3 lpm_levels.sleep_disabled=1 boot_cpus=0-7 maxcpus=4 no_console_suspend buildvariant=user...

Questions:

1) why having TWRP is needed to avoid BLOD (having patched boot image is not enough for me)

2) did anybody have successfully installed patched "Oreo" on 6p BLOD devices? Are there any features to do that specifically comparing to 7.1.2?
[Nexus 6P General] squabbi:
There should be no difference in patching the Oreo and Nougat builds of Android. I would venture to say that since we had the 4 big cores disabled after just having upgraded the OS, it may have taken a lot more time for it to boot up, although if you had waited more than 30 minutes, still to no avail, then I'm not sure what is the cause.

Also, your device not being able to boot without the patched TWRP/recovery is quite interesting, I wouldn't have thought of any correlation between the two. :confused:
[Nexus 6P General] Rage789:
I cant seem to modify the ROM. It gives me unsigned error. And some files on AIK show up as Trojans. Help me someone.
[Nexus 6P General] Tigran_:
most probably the problem is that you didn't install JRE.

go here to install the latest - java . com
[Nexus 6P General] 18yusuf:
Bad news. Reballing didn't work. That means it is the CPU fail, not the solder. I am thinking about replacing the CPU now.
[Nexus 6P General] ricbaez:
I agree guys, my Nexus 6p was running fine on the fix for 6-7 months then all of a sudden one morning it became a brick. Would not turn on , respond to the charger, or the computer. Once you get the first boot loop that's it, its basically over.
[Nexus 6P General] Sunit6k:
I've a blod device working on 4 cores along with Elemental Ex kernel 6.0. can I flashed the latest 6.06 on top of that?
[Nexus 6P General] ricbaez:
Someone uploaded a zip that you can flash that will automatically patch the boot. I think it's in this forum or it might be in the other one, flash the update first then the workaround zip.
[Nexus 6P General] Sunit6k:
Is this the one? N5X-6P_BLOD_Workaround_Injector_Addon-AK2-signed.

Would like to share my latest results.

Followed procedure with updating and automatic patching tge latest oreo android 8.1.0 and im really hapoy now for about a week.

Due to latest performance optinizations within oreo itself comparing to Nougat, my patched Nexus 6p with 4core works really nice and smooth. I dont play resource consuming games, so cant say about it for now. but the rest features look and feel without any significant or even notable degradation in performance aspects.

So i continue using my phone. Will reply back here if any.
