Oreo Security Update

Thanks for the detailed steps to fix the issue [MENTION=5288606]XCnathan32[/MENTION].

I was struggling for over 2 months. The hair dryer thing worked like a charm for me to unlock my bootloader.

I used the Oreo img and my phone is booting now :):):)

I see that there is a security update but I cannot install it.

Is that expected? It reboots midway and does not install the patch.

I did not install the EX Kernal. I did install the TWRP though.

I would like to update the status of my phone.

Just passed around 10 days from flashing 7.1.2 factory image, my phone bootloop again. This time I tried Android Oreo , flashed factory image, flash 4-core boot image, do the trick (hair dryer) again and it booted again.

For those who have to use their phone daily, please make sure you have spare phone on hand.
[Nexus 6P General] zhangla:
Just to give everyone a heads up, as this thread is so long, here is the typical stages a bootloop Nexus 6P will go through:

1. Initial bootloop - can be fixed with the 4core boot image, or an hair dryer/heat gun if you have a locked bootloader

2. Second bootloop - the second bootloop typically happens a few weeks/months after the initial fix using 4core image. in theory this is due to the failure on the 4 remaining small cores. the only way you can fix this is to use heat gun/hair dryer. none of the images, 4core or 1core, can fix this one.

3. Cold brick - the phone eventually dies suddenly sometime after the second time you fix the bootloop. Mine died 3 weeks after I fixed the 2nd bootloop with a heat gun. I guess different phones and use pattern will have different death time. Once it dies, it will not respond to any button press or combo. The only indication the phone is still there is when the battery is drained, you will see blinking red light. If you connect the dead phone to PC, you will see the generic BULKUSB in your device manager. The only fix to this cold brick is to have someone fix the soldering on the SoC, according to people who have successfully fixed this. Unfortunately, the only people who can do this fix is repairmen in China... So I just bought a new phone.

The bottom line is, once your Nexus 6P goes into bootloop, the eventual death is very close. You should just buy a new phone even if you are able to fix it with the 4core image, because it is just matter of time when it becomes a cold brick, not whether if.
[Nexus 6P General] alfred_chung:
Flashed factory image only and just do nothing, 14 days passed and now the phone boot loop again.

Now I will try Oreo to see if any extension of its lifespan.

Thanks for your information, it is my last chance to trade-in my phone.
[Nexus 6P General] zhangla:
Yes. If your phone is still booting up, trade it in ASAP. That's my mistake thinking the 4core and heat gun fix can be permanent. They are NOT, only temporary.
[Nexus 6P General] rush_art:
Hey guys, I need help.

Bootloop strikes for the first time today. Flashed the twrp and boot img, but I am not able to boot into recovery (twrp). It just goes back to the bootloop sequence of bootloader unlocked warning & white Google text over and over. Some said to flash the original rom, but I can't even get into recovery in the first place! What can I do? Is this baby a goner? :crying:
[Nexus 6P General] Einwod:
Flash the factory image. Before booting, flash the boot image and then the Exkernel. Reboot, it should start OK. That's how I did mine. Updated to Oreo November security patch yesterday. All working fine till now.
[Nexus 6P General] rush_art:
I can flash factory image and the fixed boot image fine, but the kernels from first post are .zip files, can't flash that with fastboot. :confused: And I can't boot into twrp either, it will just go into bootloop.
[Nexus 6P General] dolphin77:
Did your system really update? Please show your "about" phone screen. OTA update wouldn't flash on top of third party kernel, I believe.

PS old recipe doesn't seem to work. Same behavior as with 8.1 preview. It goes from Google screen straight to bootloader. :( Looks like some system startup check doesn't pass.
[Nexus 6P General] PieOfJustice:
are you using factory images?
[Nexus 6P General] alfred_chung:
First, you boot the phone to bootloader first, use hair dryer or heat gun or iron or whatsoever to heat the phone up, after around 30 seconds heat up (hair dryer), try start and you may boot into android. If you flashed custom recovery, you may boot in as well.
[Nexus 6P General] drshitalkiran:
Yes I tried with oct and nov 2017 angler-opr5.170623.011-factory-0e60ceb6 factory image, my phone is dead since 7 days in spide of following the procedure. any new procedure let me know
[Nexus 6P General] Einwod:
No, I flashed the November stock image from Google, then a modified boot image then finally the modified Exkernel.zip. All working fine. The OTA is not available if rooted, which I am with Magisk.

---------- Post added at 12:24 ---------- Previous post was at 12:22 ----------

Remember you must flash the modified TWRP recovery, then you can flash the zip file.

My big cores work again!!!

[IMG="screenshot"]https://wx2.sinaimg.cn/mw690/006yYEbIly1flc5c4yt76j31401z4dk2.jpg[/IMG]

I downloaded the factory image to my computer(angler-opr5.170623.011);I edited "flash-all.bat" and deleted"-w" so that I can update my device without wiping my data in fastboot mode.

After the update was done(without flashing the modified boot.img) ,my phone didn't get into bootloop while it stuck in the bootanimation.Waiting for a long time I pressed and held the power button to reboot my device and it displayed “Encryption unsuccessful",asking me to reset my device.Surprisingly,my device got into the system after resetting!

AND MY BIG CORES WORK AGAIN!!!
[Nexus 6P General] Bobbaloo:
Great!
[Nexus 6P General] mboy03241990:
I just received the November patch and I am afraid to install this.. :)

Im using stock Oreo(Not rooted) with 4 cores bootloop fix... Anyone tried to install this just normally by hitting the install button from this notification?

[IMG="patch"]https://s3.amazonaws.com/uploads.hipchat.com/191793/1367990/WW63xNU1XHGnraI/ll.jpg[/IMG]
[Nexus 6P General] rush_art:
Some update. So previously I can't get the phone to boot into TWRP at all, even when heating the cpu area with hairdryer. As a last resort I just let the hairdryer heat the phone up while I leave it bootlooping. This went on for quite a long time, at this point I'm no longer worried about damaging the internals anymore. I checked back on it and to my surprise found it booted into android. The phone was so hot that I slightly burnt my fingers when I picked it up, but it was worth it. Checked in EXKM and it seems all 8 cores are alive, at least for now. I'll definitely have to look into getting a new one sometime later, but for now I'll enjoy this great phone a little while longer. :fingers-crossed:
[Nexus 6P General] RichTJ99:
Hi,

I am running Pure Nexus for my 6P. Version was from March or April from this year. I woke up to a boot loop & did a factory reset. That didnt work, then I flashed Twrp & did a reset, that didnt work either.

I then followed the instructions here:

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

I am already unlocked so I did this:

fastboot flash boot N2G48B_4Cores.img

Then this:

fastboot flash recovery twrp3_1_1_4Cores.img

Then I rebooted & Now I sit for about 30 minutes while it is sitting on the Google screen with the unlock icon - looks like it is doing nothing.

What should I do next?

EDIT: So I tried: Flashing the latest Pure Nexus (not Oreo), then flashing N2G48B_4Cores.img & twrp3_1_1_4Cores.img. It is still just boot looping. But seems to have no problem getting into recovery.

Thanks,

Rich
[Nexus 6P General] RichTJ99:
So - I just want to make sure i am doing this in the correct order:

Flash Rom you want to use (pure nexus in my case)

Then boot into fastboot

fastboot flash recovery PureNexus7_25Fix.img

fastboot flash recovery twrp3_1_1_4Cores.img

Then it should boot? Mine gets to the animation but not further.
[Nexus 6P General] RichTJ99:
Thank you - this was a big help for me. I am back up - of course with 4 of 8 cores.

Just curious - how much of a speed impact does that cause?
[Nexus 6P General] nowbo:
Hello Everyone,

Till today there are so many Huawei Nexus 6P user like me stuck in a same line (Boot animation+ Google logo). those who success to get it live again (Huawei Nexus 6P), congratulation to all.

I am one of 1,990 SUPPORTERS, still have the last hope. Now its only need 10 sufferer like me to complete this 2,000 GOAL.

8.1 beta

Just curious, will the modified Oreo boot.img work with the 8.1 beta?
[Nexus 6P General] zhangla:
Google knows it's not a software issue, but a hardware issue.

The 4core image is not a permanent fix. I applied it and it worked for 4 weeks then the bootloop is back again, then none of the fix in this thread works. It's the SoC soldering issue.
[Nexus 6P General] RichTJ99:
Dumb question - but how much of a performance hit does this give the 6P?
[Nexus 6P General] Eddrojas:
I just received the November patch and I am afraid to install this..

I have a doubt I can update my device if I have an update??
[Nexus 6P General] W@r10ck:
Updated mine to Nov patch. My phone is still running smooth with no performance issue. Fix has been running well since i first applied it last Aug 25. Everything is stock and rooted. Yesterday was his 1st birthday.
[Nexus 6P General] TheToto318:

[Nexus 6P General] fuadhdmini:
Can show screenshot of your current system?
[Nexus 6P General] zhangla:
My had issue at 13 months mark. Fixed first bootloop with 4core img, then 4 weeks later the 2nd bootloop showed up. 2 weeks later it became a brick.
[Nexus 6P General] fuadhdmini:
Your recovery is still twrp? Can ota updates install without stock recovery?
[Nexus 6P General] W@r10ck:
Im still using twrp 3.1.1 4cores. No you cant so I updated mine through flashfire.
[Nexus 6P General] alaasagaa:
My Nexus 6p is alive again after freezing it !

I had my phone stuck on google logo after updating to Oreo, I had my OEO locked..So I freezed it for an H and then it worked and I unlocked the OEO....

To be Honest I can't follow the Instructions easily ( To hard for non android geek)...Does anyone has a video with instructions ?

The phone is working now...do I still need to flash it?
[Nexus 6P General] Alsen Lea:
The difference is not noticeable for me. Maybe even before the fix the big cluster was already throttled often.
[Nexus 6P General] mcudhaya:
Android N using 4 cores, Can I update Android from carrier update?

Hello,

Hello, I have recovered 6p from boot loop in to Andriod N by following all your steps. Now my phone is prompting to update Android O, can i update it via setting update? Or will I have to replace files that I have copied for Android N earlier?

Udhay.
[Nexus 6P General] fuadhdmini:
Thanks for your advice on using flashfire. I was from cortex ROM but I found that ROM in a long run somehow not stable (getting many crashes).

I downloaded the October full ota file and use flashfire to flash it. Less hassle compared to fastboot flashing.

Thanks. Gonna stick with rooted stock from now on.
[Nexus 6P General] W@r10ck:
Yes it's almost like your updating through OTA with few extra steps specially if boot.img is modified.
[Nexus 6P General] sylforae:
It's what I've done, like it's say. I flash the boot and the recovery, I go in TWRP and I flash the kernel
[Nexus 6P General] Aido:
Magisk is working fine, for anyone wondering!
[Nexus 6P General] naja_return:
I know this is desperate. But my bootloader is locked, this is my first bootloader locked device and I didn't expected it to bricked.

Is there anyway to unlock bootloader without booting into the phone.
[Nexus 6P General] jer0k:
i got the same issue with my 6p.

i flashed all versions of 7.1.2 with the boot image, just goes back to bootloop.

I wish i could get to recovery and try the elemetalx but there is no recovery option

even after flashing twrp or trying to boot it up through fastboot still goes back to bootloop

I think the phone is just dead. If anyone can get around this would much appreciate the help.

btw thanks OP for making this, at least some nexus 6p users can now use their phones again.
[Nexus 6P General] XCnathan32:
Important update, please read.

I made a petition for Google to release signed Boot images with this fix. That way people with a locked bootloader can fix their devices too. Check out here, and please sign, every signature counts!

http://www.thepetitionsite.com/takeaction/577/779/992/

The petition is dumbed down a lot, in case someone's Grandma or technologically challenged friend can (hopefully) understand what the petition is talking about.

Please get this out and share it!!!
[Nexus 6P General] Damo2k:
Has Google ever singed anything like this in the past before?
[Nexus 6P General] kaustubhb:
After flashing boot_4cores.img and twrp recovery try formatting userdata .... fastboot format userdata.. and then boot into recovery mode .. that worked for me and device booted normally..
[Nexus 6P General] XCnathan32:
I'm sorry to hear this :/ If this fix doesn't work for you, then if you ever manage to boot into TWRP, please adb pull the file /sys/fs/pstore/console-ramoops That way I can try to diagnose what's wrong with your device.
[Nexus 6P General] XCnathan32:
Not that I know of, but this is a such a big problem, and considering people are trying to sue Google for this problem, I think (hope) that Google decides this is a much more viable option. This fix also blew up a lot, so hopefully that gets google's attention as well.
[Nexus 6P General] kaustubhb:
If you don't mind please add formatting user data after flashing boot image and twrp .. if we don't do it device shows encrypted which doesn't allow flashing ex kernel zip file and supersu as well.. obviously you know that but just to give clear idea to others.. what they has to do ..
[Nexus 6P General] XCnathan32:
Petition is off to a great start in reddit, only been posted for 10 minutes and it's already being downvoted :confused: Sure, a petition might sound like a dumb idea that won't work, but it can't hurt to try it :rolleyes:
[Nexus 6P General] XCnathan32:
I'll add that in the OP. Also, just making sure you know, the video was to show device performance with the fix, I can't screen record the boot process/recovery, and I think a written guide is much better than a shaky video of a device screen glaring horridly.
[Nexus 6P General] kaustubhb:
Yes indeed written guide is more useful than the video..I asked you to post videos just to boost confidence of others so that more people will try and you'll get more feedback ..
[Nexus 6P General] XCnathan32:
Sent you a PM
[Nexus 6P General] Vermanucci:
no recovery

tried that, still no recovery.

even fastboot boot "twrp3_1_1_4Cores.img" without flash doesn't get me into twrp

Is the recovery affected by the same 4 core issue or is there possibly an additional problem?
[Nexus 6P General] jer0k:
I will for sure

---------- Post added at 12:15 PM ---------- Previous post was at 12:09 PM ----------

thanks for the suggestion. unfortunately this did not work for me either.

the only options that works while in fastboot are reboot bootloader and barcodes, the rest sends me back in a bootloop.
[Nexus 6P General] XCnathan32:
Recovery seems to have the same problem, it usually doesn't boot with the BIG cores enabled. You may have a different problem with your device.
[Nexus 6P General] LoyalistN7:
No fix for the battery that shuts off at 50% I guess? the bootloop never happened for me but I'm now lugging around a second massive battery [emoji367]
[Nexus 6P General] kaustubhb:
Ohh that's sad .. I tried helping you as per my basic knowledge.. try once again that's what I can say for now ..

There may be some other problem.with your device..
[Nexus 6P General] HBK008:
I set this up and it runs really really well! Had to use a hair dryer for about 15 minutes to get into the old OS and enable OEM unlocking.

Then:

Flashed boot.img

Flashed TWRP

Flashed vendor.img from PureNexus

Flashed PureNexus

gapps

su

modified EX kernel with max CPU 1632 MHz

Then after booting I used Kernel Auditor to set governor etc.

Here are my governor settings:

CPU min: 600MHz

CPU max: 1632MHz

CPU Governor: Performance

Input Boost Frequency Core 1-4: 1344MHz

Touch Boost: Enabled

GPU Governor: Performance

With Performance GPU Governor, I get very little lag when scrolling or using any of the system. Not sure why msm-adreno-tz isn't working very well for me.

I do still have animation scales enabled and set to 0.5x

Force GPU rendering: Enabled

I left Disable HW overlays: Disabled... I may investigate this more as I try it out.
[Nexus 6P General] johnnyphive:
Hi All!

Hopefully someone can point me in the right direction.

I have a 6P that was bootlooping. I applied the EX fix and my phone is now working without issue. I'm currently running STOCK (other than the EX fix and TWRP) 7.1.2 (build N2G48C). I recently was notified (finally) of Android 8.0 being available for download / install OTA on my phone, and want to do it. I was originally pointed to another thread instructing on how to do this (i thought), but as i was getting reading to pull the trigger i read again, and it seems that method was for "updates" not necessarily "upgrades". I could have read wrong, or i could just be paranoid of bricking my phone. If anyone can point me in the right direction to get my "mostly" stock phone upgraded for 7.1.2 to 8.0, i would greatly appreciate it.

Edit: The method i was origianlly pointed to mentioned using FlashFire, loading in the OTA update, a "Stock" boot.img from my current build, and the modified "oreo4cores" boot.img, adjusted the order in which they are flashed, and clicking "go".
[Nexus 6P General] mivec1756:
Hi good night. i'm having a problem with my 6p again. was stuck in bootloop and got it fixed. it worked fine for about 2 months or more until today. i restarted it and it reached the screen with the jumping balls and just cut off. since then it never came back on. i plugged it in and it doesnt seem to be charging. i cant get into bootloader or recovery it is as if its completely dead. when i plug it into windows 10 pc i'm hearing connecting sound but nothing shows up. device manager has yellow exclamation " unknown usb device device descriptor request failed" i have all the necessary drivers installed cause its the same pc i used to fix it when it was stuck in bootloop. any advice?

[MENTION=5288606]XCnathan32[/MENTION] can you please make a 4 core boot.img for benzo Rom

https://xdaforums.com/nexus-6p/development/rom-benzo-rom-t3264478
[Nexus 6P General] zhangla:
If you read previous posts on this thread, you will know:

1. first bootloop - 4core fix works

2. second bootloop - have to use heat gun or freezer to get it work

3. soon after 2nd bootloop is fixed, it will become brick

my advice to you is once you see the first bootloop and fix it with 4core, trade it in ASAP and get a new phone. there is no software fix.

I tried installing the update and it didn't work... Verification failed error..

Im also using 4 cores and updating via OTA doesn't work.. Can you please point me where to manually download the November patch? I will also try to flash it via flashfire.

I found this - https://www.androidauthority.com/november-2017-android-security-patch-pixel-nexus-812811/

but Im not sure which one to download and use the OTA or the factory image.

Just Thank You All !

My Nexus 6P was not configured as required in "Developer Mode", I was blocked with Google Logo BootLoop ! No Reset Factory available ! Just a brick !

After some readings on your Forum and followed your advices, I removed SIMCARD, I dried the battery, by "dried" I mean just red led appears when you press Power Button, but Google logo does not appear.

Then I heated alternatively both side with hair-dryer until I CANNOT TOUCH the device and I plugged the charger. At this stage, even plugged, the device does not switch-on because of temperature i think, just red led is blinking.

I let the device cool down for 10 minutes, and finally it booted by itself and requested the PIN CODE. I activated OEM and Debug USB in "Developer Mode".

I entered Recovery mode and I did a Factory Reset :)

Thank You All !

-----------------------------------------------------------

Juste merci à tous!

Mon Nexus 6P n'a pas été configuré comme requis en "mode développeur", j'étais bloqué en BootLoop avec le Logo Google. Aucune réinitialisation d'usine disponible ! Juste une brique!

Après quelques lectures sur votre forum et suivi vos conseils, j'ai enlevé ma SIMCARD, j'ai vidé la batterie, par "vidé" je veux dire juste la led rouge apparaît lorsque vous appuyez sur le bouton d'alimentation, mais le logo Google n'apparaît pas.

Ensuite, j'ai chauffé alternativement les deux côtés du téléphone avec un sèche-cheveux jusqu'à ce que je ne puisse plus toucher l'appareil et j'ai branché le chargeur. A ce stade, même branché, l'appareil ne s'allume pas à cause de la température je pense, juste la led rouge clignote.

J'ai laissé l'appareil refroidir pendant 10 minutes, et finalement il a démarré tout seul et a demandé le code PIN. J'ai activé OEM et Debug USB en "Mode Développeur".

Je suis entré en mode de récupération et j'ai fait un Factory Reset :)

Merci à tous !
[Nexus 6P General] mboy03241990:
I've updated mine via flashfire using this Nov update 8.0.0 (OPR5.170623.011, Nov 2017) and it worked! Thanks! hehe

NOTE to newbies like me:

1. I rooted first for flashfire to work

2. follow this

3. I had to re flash the 4 cores img to fix the boot loop issue again..
[Nexus 6P General] ricbaez:
OK, so I got a random reboot days ago, bootlooped like hell. Able to boot to TWRP using the modified image. What happens is I can run a ROM (nitrogenOS) and use EX kernel (honestly I feel like EX kernel is giving my phone issues since using the stock kernel so far hasn't looped), and it'll boot up and run fine for a bit, all 8 cores. Then it crashes and restarts. I can factory reset and flash another ROM and and it'll bootup (after looping 3 times). I'm not using the modified EX kernel, I cannot use it because if I do the ROM stays stuck on the boot animation then goes back to recovery. How am I able to boot up with all 8 cores? I shouldn't be able to if the big cores are botched, it doesn't make sense to me, perhaps I have a software issue? SO far I've only had random reboots with EX (followed by bootloop) stock kernel so far has not given me issue

Edit: On stock Kernel once all 8 turned on it crashed, I enable 6 only (CPU 6 & 7 OFF) and it doesn't crash.
[Nexus 6P General] mboy03241990:
Before the bootloop happened to me Im also getting random reboots since Nougat to Oreo. I have no choice but to use the 4cores fix...
[Nexus 6P General] ricbaez:
When I run hexacore mode, I dont get crashes, but 8 cores yes, my hunch is that one of the big cluster cores is causing the issue in my case. Unfortunately, when I flash the EX kernel 4 core mod, I cannot boot into the rom. It boots to the boot animation and then after 5 minutes it goes back to recovery.
[Nexus 6P General] Snowers96:
I have a question, all the people suffer the 2nd/3rd bootloop after aply the 4 cores fix, or hopefully there is people surviving with this fix for a long period of time?
