Phone still not working after flashing

Hey there! I've been following this entire thread and trying out a few things to try to get my nexus 6p working. I started off with this post https://xdaforums.com/showpost.php?p=74041226&postcount=1408 The phone got stuck in a loop with a white Google screen and a screen that says "Your device software can't be checked for corruption. " I then flashed twrp. into recovery. The phone wouldn't boot into recovery, so I heated up the phone. After a while, it loaded twrp. I then followed these steps which another user posted a while ago.

I did everything besides formatting the partitions, because I think I had already formatted them earlier (everything was erased). Once I finished installing the elemental kernel, the phone just did the same thing as earlier with the white Google logo. I didn't get the 4 dots jumping. I heated up the phone again, and then got 4 dots jumping. The 4 dots were different than normal (I was on 8.0 before, and I installed 7.12 through the instructions, so I guess it explains the difference). However, after a while it just went straight back to the white Google logo and did the same thing as before. I experimented with more heat, and at one point the loading stopped and it just showed a charging screen.

The problem now is that if I select recovery boot from the fastboot menu and apply heat, it won't load twrp. So now I'm just stuck with the white Google logo repeating. I'm not sure what else to try, since nothing has worked. Does anyone have any suggestions?

Thanks!

Thanks .. I have Android 8 OS and this bypass worked! Thank you again.!
[Nexus 6P General] Clinton L.:
My 6p is back up and running with the 4 cores 8.0 img. I'm rooted with magisk and have TWRP installed. So my dilemma is how do I now update my phone with the latest October patch ota update and future updates for that matter?
[Nexus 6P General] paracha3:
I came here looking for the same answer :)
[Nexus 6P General] W@r10ck:
3 ways that I know so far:

1. Flashing the img

2. Flash thru TWRP

3. Flash using Flashfire

Just browse or search this thread as someone has posted the steps.
[Nexus 6P General] galaxy s4 nutjob:
So I've gotten the phone back booting how do u flash pn? Just fastboot flash the pn moded boot.img ? Then boot to twrp n flash ex mod kernel?
[Nexus 6P General] mboy03241990:
So just to clarify. I'm all stock(NOT ROOTED) before I flash this img thing to fix my 6p.. So after this I will not be able to receive updates normally just like before and need to flash new IMG normally ?
[Nexus 6P General] W@r10ck:
To be able to apply the fix I think you will need to modify your recovery(someone could correct me if im wrong) that means you won't be able to update normally although you would still receive them. I think i may have tried the 4core.img fix without flashing twrp and it bootloops on me.
[Nexus 6P General] paracha3:
Will step#1 factory reset (wipe) the device?
[Nexus 6P General] NoobInToto:
Coming here is not enough. Search for the goddamn method.

Search ' updating without losing data' in this thread.

PN boot image for 7/25 build is available in the first post. Flash the modified 4corefix twrp, flash PN, and flash the respective boot image. Optionally, flash ex kernel in twrp after flashing PN.
[Nexus 6P General] W@r10ck:
Yes and No.

Yes - if you you use the command flashall.bat

No - if you edit the command or flash manually.
[Nexus 6P General] maity-iman-2015:
Anyone tried this Android 8.1 ROM: https://xdaforums.com/nexus-6p/development/rom-t3488519

Is it recommended to flash other ROMs on a boot looping Nexus 6p?
[Nexus 6P General] vyrus027:
Guys, I wanna ask does really turning down the resolution of this display will really help to improve performance? Can it also somehow help about heat issues? Does it have any improvement on the battery or just making the cpu work less? Thanks! :)
[Nexus 6P General] Face_Plant:
I ran my 6P at both 720P and 1080P for a few months and saw a very slight bump in performance. It wasn't noticeable enough to make it worth putting up with the fuzzy text (only an issue at 720P) or magnified recent apps screen (happens at both 720P and 1080P).
[Nexus 6P General] vyrus027:
Thanks for the info. Btw, I heard somewhere that disabling 4 big cores shows better performance in benchmarks since no more heat throttling than having full 8 cores running? Is it worth it to disable 4big cores just to get rid of heating issues?

How noticeable is the impact of having 4 cores being turned off?
[Nexus 6P General] Face_Plant:
Disabling the big cores will completely destroy your phone's performance. That's what they're there for: to make your phone perform. Disabling them will help reduce heat, but intense tasks like gaming, using the camera, Snapchat, etc will be very laggy and difficult. Lighter tasks like texting won't be effected too badly.

I would recommend underclocking the big cores rather than disabling them completely to preserve some performance. I have mine underclocked to 1440MHz and performance is still decent, but I only use my phone for light stuff like texting, calls, music, and browsing XDA. I don't do any intense gaming, Facebook, etc.

A good governor profile like Saber_V2 or GlassFish will help with both performance and heat. A quick search of the 6P general section should bring up the thread about what governor profiles do for you along with how to use them and links to popular ones.
[Nexus 6P General] Trenth2247:
For those of you already on 4 core mod and want a good setup for performance and battery life. Im personally running pixeldust rom with flash kernel with drunksauce lite as the governor profile. I have also downgraded the resolution to 1080 for increased performance. I also have wakeblock enabled and naptime installed. Hope this helped someone
[Nexus 6P General] javitomen:
do you try this man?
[Nexus 6P General] aoaleman:
Doesn't work, as we don't yet have a working modded boot image for 8.1.
[Nexus 6P General] lu4414:
Hi,

so last night i was a victim of bootloop of death, i was running android 8.0. As soon as it happens i think it was a common bootloop and flash android 7.1, as far as i know the flash was sucessfull. Now i follow the steps here and flash 48B_A4 boot.img, but nothing happens, i mean it passed the Google screen but now get stucked in a common bootloop, what to do?

Best regards and thanks very much for the awesome work dev
[Nexus 6P General] Quetzalfp:
Also me

Hi guys, you can count me as a part of this group, my Nexus 6p started to loop yesterday, I was listening to music and charging the phone. Unfortunately my bootloader is locked and also the USB debugging is off

So, I was reading this thread and some others, and I think that my only hope is to try to boot the device by heating it as it seems is the more certain way to do it, right? Or there is another procedure that I'm missing?

Thanks!
[Nexus 6P General] alfred_chung:
I want to share my experience for reviving my 6p:

1) Flash Oreo oct 4 core IMG.

2) Flash twrp 4 core recovery.

3) Boot to recovery, got bootloop.

4) Use hair dryer, heat up 1 min, booted to twrp.

5) Flash ex kernel, left all setting default.

6) Phone booted normally, set my account, after few minutes cool down, it bootlooped again. Then, I repeated step 1-5 again, tried to set big cluster frequency to lowest, but bootloop again after cool down.

7) Flash factory image (7.1.2 Aug 2017 security patch), after that, it booted normally until now (15 hours).

This is the first time I heard (and tried) to fix mobile phone by using hair dryer!
[Nexus 6P General] Nynsu:
If I flash a custom ROM and then flash the Elemental X modified img, will I be able to boot normally?
[Nexus 6P General] lordlad:
So i got this dread issue this morning on my N6P (Stock Oreo, bootloader unlocked, Magisk rooted).

Tried to flash the custom recovery and oreo boot image still no go.

Is the 'hairdryer' method really the only way for me going forward?
[Nexus 6P General] aoaleman:
No, flash this boot image instead:

Ok let me try this when i get home...i am using my old Nexus 6 as my spare backup at work for the time being..

will update here later.
[Nexus 6P General] mpbtejada:
Will I still be able to update to Oreo? Coming from 7.1.2, do I need to factory reset if I flash Oreo 8.0? Or wipe cache and dalvik?

From desperation I Tried hairdryer to do heat test for 10 min (FAILED). Then heat gun till the screen went dark {up to 350 degrees celsius} [ yes, the battery was charged and had no problem "flashing google" for a very long time] (EPIC FAIL)

Now back to flashing Google and out of options

Please HELP me

Sad programmer
[Nexus 6P General] alfred_chung:
At least you are able to boot your phone by using this method, just cost you a little bit electrical power, why not?

---------- Post added at 07:38 AM ---------- Previous post was at 07:33 AM ----------

You have to aim your hair dryer to the area under the camera, apply around 1 min, your phone should boot normally.
[Nexus 6P General] DodoGTA:
Try to use "fastboot flashing unlock" instead of "fastboot oem unlock"
[Nexus 6P General] Elirayo:
4 core patch didnt last more than 14 days

So after i got the bootloop about 5 months ago i somehow bumped into this great thread. As i did not enable the oem unlocking before the bootloop, i left my beloved paper weight in the freezer for several hours. As if it was magic, the phone booted for a couple of minutes and i was able to change the settings. After unlocking the bootloader, i tried to apply the oreo patch but that didnt work. I then flashed the android 7 4 cores patch and my brick was finally usable again.

But. 14 happy days have passed, and my nexus decided that bootloopoing is the preferred way of spending it's life. So now i have a paper weight with the 4 cores patch. Any ideas or should i finally buy a new phone?
[Nexus 6P General] maity-iman-2015:
No, waiting for the good news of 4 cores boot img for android 8.1 ...:(
[Nexus 6P General] lordlad:
applied october oreo patched boot image....

still no go :(

Try to tap phone on the palm of your hand in the chip area then to flash again modified kernel and to clear cache. Mine 6p acted as yours and that helped
[Nexus 6P General] galaxy s4 nutjob:
does this modified twrp image break the ability of an app like nandroid manager from working correctly? im trying to extract apks i lost in the fire
[Nexus 6P General] toycz:
Hello,

i managed to boot the device again by flashing oreo boot.img and patched twrp. Phone boots just sometimes and even if it boots it restarts randomly. Also apps crash all the time. Is there something i could do about it? I tried cpuz and cores 4-8 stay stopped, so the patch worked.

thank you
[Nexus 6P General] javitomen:
Any advice im in Oreo, but when my phone hace 20% battery automatic the battery drain and turn off

Sorry for my bad english
[Nexus 6P General] Quetzalfp:
Yikes, I froze mine and suddenly the color dots appeared but the phone shutted down, I tried a couple times more but the phone started to bootloop again, should I wait or connect the charger to help it to boot completely?

thanks in advance
[Nexus 6P General] Elirayo:
I froze mine with a full battery, so maybe it shuts down because the battery is drained? And if thats not working, maybe you should try the heat gun technique.

---------- Post added at 07:37 AM ---------- Previous post was at 07:32 AM ----------

I'll try that in a few days. How long did your solution lasted (or, hopefully, is lasting), after you flashed the fixed kernel?
[Nexus 6P General] 3l1k:
One week for now
[Nexus 6P General] FlyOnTheWall43:
Would you be willing to provide boot images for older factory images or explain what you did to create these modified boot images? My wife's phone got this BLOD, but due to a critical work related (and very poorly supported) app, she has to lag behind the current android version by 3 to 6 months. I'm not exactly sure which release she's on, but if you could make these boot images for the N2G47W (Jun 2017), N2G47O (May 2017), and N2G47H (Apr 2017), it would be greatly appreciated. However, I completely understand if you don't.
[Nexus 6P General] Quetzalfp:
I used the hair drier for around 20 minutes, the device heated a lot but still not booted. The closer I get was by freezing it, the color dots appear but the device bootlooped again.

Also, I don't know if this happen to all of you, when the device is powered off and I plugin the charger or to an USB port, the battery logo appear and then start to bootloop immediately, is this normal for the BLOD?

Any advice is welcome, I'm hopeless and broke, my spare is a Sony Ericsson WT19a :'(

Thanks!

Edit: I've just noticed that when I freeze the phone and plug the charger the device just shows that is charging -battery logo filling up- don't know if this is relevant...
[Nexus 6P General] Phazmos:
Fwiw - I had the start/loop thing when plugged in. But so far so good for a couple days now with the fix and/or 1 of the fixed kernels. Still get a no battery shutdown every now and then, but that's another issue. At least I got a mostly working device again.
[Nexus 6P General] McCoy 25:
Got notification for software update

My nexus 6p went bootloop 2 months ago and I performed the fix using this guide. So yesterday I received a software upgrade notication and I just gave it a go knowing if won't work since I have a "custom boot img". Then to my surprise my phone booted after installing the update. I went to check the cores and all 8 are working! Android pay is also working!

i have nexus 6p bootloop and no recovery mode i unlocked bootloader and flash 4core boot but same problem bootloop and no recovery mode can help ?
[Nexus 6P General] Quetzalfp:
:( glad you make it, hope I have some luck soon
[Nexus 6P General] Phazmos:
I did flash a few N factory images first trying to fix (before finding this thread). But I don't think that would matter. Nothing worked except this. If your issue is what this fix addresses, it should work. Phone is more than usable with this, at least for every day stuff - some cpu intensive things are noticeably slower, everything else isn't very noticeable, if at all. Keep trying, it was worth it.
[Nexus 6P General] maity-iman-2015:
Is it android 8.1 update? was your phone rooted?

As I tried to update (via google push update notification) 2 months back (on my rooted, 4 core boot img) but didn't work, got only bootloop!! :confused:
[Nexus 6P General] McCoy 25:
Not rooted, just got a software update notification (900+mb), downloaded and installed it. The update is the Oct 5 security update (OPR5.170623.007). My phone is back to normal, all 8 cores are running and safetynet is good
[Nexus 6P General] javitomen:
It's some kind of magic?, Now I'm tempted to install 8.1
[Nexus 6P General] McCoy 25:
TBH i don't know. But everything is back to normal
[Nexus 6P General] javitomen:
Have you try with the 8.1 preview?
[Nexus 6P General] McCoy 25:
no. I'll wait for the OTA.
[Nexus 6P General] mattiamatrix:
The bootloop of death happened also to me... :(:( but I'm happy because I booted using the hair dryer. Does it mean that I have the problem with the core? or Could be another problem, maybe because I'm in the 8.1.0 beta?

Is there any way to understand if I really need to flash the mod with 4 core?
[Nexus 6P General] elfanto:
Anyone try this? I really need to flash a MM rom for spoofing
[Nexus 6P General] SlimSnoopOS:
Clean flash any factory image and use it for awhile. If the phone reboots endlessly then you have your answer.
[Nexus 6P General] javitomen:
I have the OTA of the developer preview do you think I should give a try?
[Nexus 6P General] 3l1k:
My suggestion - wait a week or two because i have had same "magic" with fresh installed androud 7.1.2 but one week later my phone started bootlooping again and only 4core fix helped
[Nexus 6P General] berry2gold:
Hello all, please i need help......my Nexus6P is back to bootlooping after 3 months of enjoying this fix.

i tried flashing it with the andriod O and it came back on, while i was setting up the phone it went back to bootlooping.

I can't for the life of me get into recovery mode again to access twrp. I have even tried the hair dryer and heat gun method but no luck.

Please i need help!!!!!
[Nexus 6P General] Phazmos:
If you can't get to boot loader - you're done. Since this fix works around a critical hardware failure, I guess you've been lucky to get more life out of it. I just ordered a g5s plus, I can't be without a phone and this just started about a week ago for me, so I'm getting ready for it to really bite the big one. Good luck
[Nexus 6P General] berry2gold:
I can get into boot loader.....i just can't get into recovery
[Nexus 6P General] Phazmos:
You using the 4 core version given?
[Nexus 6P General] berry2gold:
Yes but still no luck :crying:
[Nexus 6P General] DaKoin:
What method did y'all use to root this phone once you flashed 4core boot? I rooted using SuperSU zip but now my Snapchat is not working. I normally hide using magisk but magisk says I would need to unroot if I already am and use their root method.

My question is...will magisk root work fine with this phone and all the problems it's having regarding blod??
[Nexus 6P General] DodoGTA:
Yes (flash it after removing all traces of SuperSU and reflashing 4-core boot image or a 4-core custom kernel of your choice)

Hello Everyone,

Allow me to stand with all of you (Nexus 6P).

Today is 37 days of suffering, I'm following every bootloop fixing related post for solve my device problem. It's stuck on bootloader animation (after white Google logo). I have downloaded several factory images and custom ROMs and apply each & every one but result at the end is same. TWRP running, done factory reset, even bootloader is unlocked.

I try factory reset 8.0. then apply (stock 6.17, 8.0 firmware)

fastboot flash boot Oreo4Cores.img

fastboot flash recovery twrp3_1_1_4Cores.img

fastboot reboot

Result:

Google white color logo

Then

Bootloader animation (attached picture)

Stuck here and continue running this (never stop until charge going down)

So, requesting to all of you for helping to solve this.

Thanks

[Nexus 6P General] alfred_chung:
Try not to use Oreo, going back to 7.1.2 may revive your phone, and it is what I did and how I revive my phone with 8 cores working up to this moment. (around 7 days after bootloop happened).
[Nexus 6P General] javitomen:
so returnong to 7.1.2 magical again the 8 cores work again or what you do?
[Nexus 6P General] nowbo:
Hi,

Returned to 7.1.2 was my first attempt when my device started this bootloop. This magic as other's may have success on that but not with my Nexus 6P.

I tried every single factory images and also including custom ROMs.

Now its only showing the mind blowing boot animation. Seriously speaking almost loving it, because the amount of time watching this :).

Same here, Android 8.0 4 core, yesterday night (at 1 AM) it was 92 %, today I woke (at 9 AM) up with 77 %, almost 15 % reduced without touching the phone. Today I will try to use greenify and EX kernel 5.03 kernel. Tomorrow I will let you know if it works.
[Nexus 6P General] Fynt1k:
Is there a risk of getting bootloop again after fix?
[Nexus 6P General] zhangla:
It's not a risk. From my own Nexus 6P and many others experience, the fix is only temporary. Bootloop will come back, and the phone will eventually become hard brick, e.g. you cannot even turn it on. It took 3 months from my first bootloop fix to the hard brick. YMMV.
[Nexus 6P General] fuadhdmini:
I believe not every device is the same. I used the bootloop fix since somewhere in the last week of July and mine still running ok with this fix/ 4 cores.
[Nexus 6P General] zhangla:
From most developers, the problem is hardware related, SoC soldering issue. Yours still works maybe because the soldering is still holding up. I used heat gun on the back to get rid of the bootloop issue after the 4core fix no longer worked. I believe that heat gun approach accelerated the SoC soldering issue.

Worked for me

My Nexus 6P just bootlooped, assumed it might be a bad mod but even after factory resetting, the phone still wouldn't boot.

Flashed the 4-core mods and now everything is working again. I guess my phone has the infamous bootloop of death. :(
