Hi everyone..

I really need help with my lemon of a 6P, I was running the latest version of Marshmallo

- How can I apply this fix to get my phone booted? OP can you help with a version for Android 6.01?

- Worst case scenario: upgrading to Nougat, can i flash that without losing my data? If so how?

- Can anyone else confirm that the heating worked? I dont want to damage my phone.
[Nexus 6P General] SlimSnoopOS:
Do you have any other USB ports that you can try for ADB? I don't use Windows so I can't offer specific help.

You are using "ADB" interchangeably in your reply so forgive me for stating this again. ADB only works in recovery or while in a fully booted Android. Fastboot only recognizes the device when it is in the bootloader. Does ADB recognize your phone in Android OR fastboot recognize the phone when its in the bootloader?
[Nexus 6P General] sharpz811:
Naw it doesn't at all i would have the phone in bootloader mode connect to PC and type the command adb devices and nothing shows up never tried any other command because i figured they wouldn't even work since adb dint even recognize my device
[Nexus 6P General] SlimSnoopOS:
That is the issue. What you are doing will not work and that's what I have been telling you. Absolutely no adb [command] will work while you have the phone in the bootloader. ADB is used mostly for pushing/pulling files between the phone and computer, installing updates, bug reporting, and ensuring you have a working environment to proceed to use fastboot. That is why you need to be booted into Android or in a recovery to use it.

Fastboot is commonly used for flashing manufacturer software like factory images or unlocking the bootloader. ADB and fastboot are two separate functions even though the computer interface is the same.

While you have the phone in the bootloader, you must execute fastboot commands: "fastboot devices" or "fastboot flash boot.img" or (this next command will wipe your phone) "fastboot OEM unlock," etc. Again, the interface on your computer will look the same but your commands are dependent on what mode the phone is booted into.

Could you follow the instructions in the guide below for a refresher on issuing fastboot commands? You should read this to better distinguish the differences.

Your a good man slim just by what you've said alone actually helped me distinguish the two lol i will try when i get home from work but what's still weird is that my phone still ain't recognized by pc at all just strange and that's why i have a feeling fastboot or adb won't recognize my device but I'll still give it a go

Thanks so much for your help bro

I was browsing like normal, my phone froze and crashed to the Google logo and is now in a bootloop. I wasn't on 7.1.2 though, so flashing these boot.imgs will cause another bootloop entirely right? :( Any suggestions? Should I just try to flash the factory image and then flash the modified boot.img? Recovery sends me back to the lootloop again. So TWRP is out.

Was only these boot.imgs made? or were older ones made too? Because I'm sure itll lead to another bootloop if I flash a 7.1.2 over an I think 7.0.2. I don't even remember what version I'm even on honestly... I couldn't do ota updates and never bothered updating my system software through other methods.

And is there any way to save my data?:( I had almost the whole phone filled with irreplacable videos and pictures and memories and music and so many documents for school and work that I can't afford to lose. If there is any way at all to backup my data, please let me know. Can I ABD pull it from the bootloader?
[Nexus 6P General] sharpz811:
Jeez save exact thing happened to me i was in titanium backup and bam random bootloop of freaking death at that time i was on 7.1.2 but i flashed stock oreo within minutes and got back up and running thanks to this amazing Dev! So here's what i did is simply follow the instructions in op and your good to go. I'm not sure if data still remains after a flash for me i had already wiped my data in hopes of trying to fix the bootloop but didn't matter because i have everything backed up in the cloud always.
[Nexus 6P General] nishu02:
Thanks for the information regarding re-locking the bootloader. So the 4cores boot.img gets replaced by stock boot.img in the process.
[Nexus 6P General] snappycg1996:
So I go ahead and flash the modified 7.1.2 boot.img? We're you on 7.1.2? I'm just worried doing that will brick the phone further. Or did you flash the two files, boot it up, and then it worked so you flashed Oreo?

---------- Post added at 05:01 PM ---------- Previous post was at 04:59 PM ----------

Did you just flash the two files and booted then flashed Oreo? Or did you flash the files then booted to make sure it worked then flash Oreo? And we're you on 7.1.2? I believe flashing this boot.IMG will create another loop in itself since idk what version k was on and I'm sure it wasn't 7.1.2

---------- Post added at 05:44 PM ---------- Previous post was at 05:01 PM ----------

Is there anyway to preserve my data?:( won't factory resetting in TWRP delete the data?

---------- Post added at 06:15 PM ---------- Previous post was at 05:44 PM ----------

So there's still hope to save my data before I factory reset in TWRP to get rid of the password? I'm not even sure what version of Android I'm in when this bootloop thing started... I just want to save my data.

Success with EX kernel

So I had stock everything and a locked bootloader on 7.1.2 (I have replaced battery and screen), got the bootloop last night after a random restart. Eventually got it working and thought I would share exactly the steps I went through in case it might help.

1. Use fastboot to unlock bootloader

2. Here is where I tried various factory images through fastboot method... 8.0, back to 7.1.2 (Aug), 7.1.2 (Jul), 7.1.1 (Apr), 6.0 (Orig) ...should add I was factory resetting after finishing each image flash.

3. At this point, I was still in bootloop and about to give up. Found this thread. Went to 7.1.2 (Aug) then applied the 4 core 7.1.2 boot.img. No good, still in bootloop.

4. Fastboot to 8.0 factory again, applied 4 core 8.0 boot.img and latest TWRP. Used TWRP to install 4 core patched EX kernel version 5.03. TWRP factory reset.

5. Success!

This was about 7-8 hrs ago and phone is still going. Not a ton of noticeable performance loss, but I've just been emailing/texting so far. Boots fine from reset and a hard power cycle.

Hopefully this gets me to October...
[Nexus 6P General] snappycg1996:
Omg guys I'm dying right now. So I tried the hair dryer trick for about five minutes and my phone booted!! A HAIR DRYER! Lol now I need to back everything up. Can I go ahead and flash the kernel to disable the cores so this doesn't happen again?
[Nexus 6P General] SlimSnoopOS:
Yes. If this thread has shown anything, there is no guarantee this will not happen again.
[Nexus 6P General] snappycg1996:
Yeah, it crashed after about fifteen minutes, bootloop. Can I just flash the universal EX kernel and then be good to go?

At least I can revive it, even if it don't work, temporarily, to save files.
[Nexus 6P General] SlimSnoopOS:
Sure, if it helps and you are currently using the proper version of Android beforehand.
[Nexus 6P General] Kittykittychuchu:
Stuck on Google logo now

So I have flashed twrp, flashed Oreo4cores using twrp (I am running on Oreo), Flashed custom kernel 4cEX5_03.

Still I am stuck in Google logo screen. Not bootlooping anymore but just stuck on that screen. What did I miss?

I'd appreciate everyone's help, I am new to this flashing thing. Thank you! =)
[Nexus 6P General] dan_l2:
Worked like a charm

Flashed the 48C build and then the modified boot.

Thank you very much.

Considering going back to it from my crappy LG V20, but not sure if I should because it uses only 4 cores.

Tengo un nexus 6p en bootlop. Tengo el botloader bloqueado.alguna solucion?

[Nexus 6P General] sharpz811:
Just a quick question and Google didn't help. how long will this phone last using only 4 cores because i planned on keeping this phone until the end of my context next October. Thanks in advanced.
[Nexus 6P General] SlimSnoopOS:
Nobody here designed the phone so nobody knows. It's variable. Some people have had this fix work for a month, a few weeks, or a few days and the device suddenly resumes crashing.
[Nexus 6P General] sharpz811:
Dammit! Now I'm gonna have try and hustle a next phone until my contract is up but for me at least I've been using this fix on stock Oreo with the stock 4coresOreoboot.img for about a week now and do far no issues and the phone is pretty snappy I'm just probably not gonna flash anything in hopes of reducing any risks of bootlooping. Thanks for reply bro.
[Nexus 6P General] Var14ble:
Hey guys, not sure if there's any hope for me or not...

About a week after updating to Oreo, my phone was only booting into the bootloader, not even the recovery, until I factory reset and flashed stock 7.12. After doing that I managed to get into the recovery but still not to have it boot completely. After reading through this thread, I tried flashing the boot.img and it didn't work. I've tried rolling back to 48C, 48B, and then back up to oreo, and I couldn't get it to boot normally with any of them.

I then tried flashing EX since helped some people, but when I tried to use TWRP it wouldn't work on oreo, and even after rolling back to 48C everything was ridiculously slow, like it took several seconds to register a click and it froze completely half the time so I had to restart it a bunch. After finally managing to install EX kernel, I still can't get my phone to boot, and at this point I'm completely out of ideas.

I have an LG G6 on the way, but since it's going to be at least two weeks until it gets here I figured I might just try and get a little more life out of this brick. Does anyone know if I'm doing something wrong, or are some of us just completely out of luck?
[Nexus 6P General] boeder9:
So flashing stock oreo and then the modified oreo boot.img seems to be doing the trick for a few people.

How do i 'dirty' flash Oreo or Marshmallow (since im on 6.01) ie without losing my files. Also does a factory reset erase all my data and app data?
[Nexus 6P General] Cdub1976:
Worked like a charm op. Fixed my wife's 6p with the kernel as well.
[Nexus 6P General] heman13:
Issues persist. Cannot enter the bootloader mode.

Downloaded the platform 1.4.2, and the Elemental X kernel version 4.12, universal zip.

Have also enabled the OEM unlocking and USB Debugging.

But when I start the phone with POWER + VOL button, at the bottom among the 10+ lines of info, it shows that the Device is LOCKED. When I try to press on bootloader or on Recovery, the phone just goes back to bootloop.

Please help. This thing is really poorly done by Google (my ex-employer).

Thanks in advance!
[Nexus 6P General] cynsx:
My Nexus 6P had boot loop with 7.1.2 a week ago.

I factory reset it, flashed the stock Oreo and no bootloop for few days.

Is it safe to stay with everything which is stock now or should I apply the fix?

Your good your one of the lucky ones this fix is a last resort when your phone meets Mr. Blod
[Nexus 6P General] ramhses02:
I'm unable to fix my 6p. I tried flashing all the files here, but no luck. Any advice or help please

The screenshot is the image I got when I flashed the files. Now it is booting that screen over and over along with the Google logo
[Nexus 6P General] sharpz811:
Can you please share exactly what files you've flashed and in what order?
[Nexus 6P General] ramhses02:
Thank you for your reply. Well, first I unlocked the bootloader. Then, as my 6p is with 7.1.2, I flashed N2G48B_4Cores.img and twrp3_1_1_4Cores.img. Then I tried with 48B_A4.img and after that with 6p48C.img, always flashing twrp.

I have also flashed only the img files (without twrp) with no luck.
[Nexus 6P General] sharpz811:
Ok so here's what i did and i wish i never wiped my data prior to doing this when i was trying to fix the bootloop myself because i never realised all you needed was the recovery and boot but whatever.

1. Make sure you have fastboot and adb drivers installed

2. Download stock Oreo firmware from Google

3. You should already have twrp3.1.1 and also download oreo4cores.img and place all these files in one folder (I've only extracted bootloader, radio, data, and system of i remember correctly and flashed those separately in fastboot mode)

4. Then boot into fastboot and startup up fastboot on your pc where you've placed the folders.

5. Using fastboot commands Flash twrp, oreo4cores.img, bootloader, radio, data, system. I'll double check the exact files and order but that's exactly what i remember and exactly how i would do it.

6. Fastboot reboot and your phone should start up within minutes at least that's what worked for me

So it's been over a week and no issues no hiccups and phone is running real smooth.
[Nexus 6P General] Scooby__Doo:
I've used this fix successfully on my stock Nexus 6p with Android 7.1.2, Security Patch Level Aug 5th 2017 and the phone has been running well. This morning I've received the Android Oreo OTA update to my phone. I assume the update will fail due to the modified system files so how do I go about updating my phone officially without the update failing and also avoiding any further BLOD issues?
[Nexus 6P General] p.r.kataria:
Stuck in Boot animation after oreo update.

setting it up for oreo, my phone remains in fancy google bootscreen animation. How long should I wait? Am I doing anything wrong. I flashed 8.0 img, twrp and exkernel.
[Nexus 6P General] xian2380:
can you please update the ex kernel for nougat？
[Nexus 6P General] TheToto318:
New update ?
[Nexus 6P General] NoobInToto:
Yeah, I got it too, and I am on first Oreo build. Perhaps this is the stable one that is supposed to be released to nougat users via ota.
[Nexus 6P General] TheToto318:
Ok thanks ?

not september security patch ?
[Nexus 6P General] NoobInToto:
It has September security patch from what I read.

I have no clue how to install it. I know the update will fail due to modified boot image. The phone will also bootloop if I revert the boot.img
[Nexus 6P General] TheToto318:
This update ?
[Nexus 6P General] NoobInToto:
Yeah. I guess the size of the update is huge because it is the original intended ota (I'm having a deja vu. Did google do this with nougat or marshmallow too?)
[Nexus 6P General] TheToto318:
I dont know but i will wait
[Nexus 6P General] SlimSnoopOS:
There is certainly precedence. Google has provided a monthly security update before that was considerably larger than the month prior even though it was still the same OS. They did so in March/April 2016 for a Marshmallow performance update to correct widespread issues on both Nexus 5X and 6P. This isn't the norm though.
[Nexus 6P General] metallicant:
Couldn't we just download and install the image and then just simply apply the 4 core Oreo patch?
[Nexus 6P General] buggatti:
I am about to buy a 6p from craigslist. How can i tell if the phone is on 4 cores bootloop fix or not.,

Thanks
[Nexus 6P General] c4ndy:
Then you would need the image to be signed, hence the petition created by XCnathan32 to Google.

EDIT: nevermind, misread that
[Nexus 6P General] SlimSnoopOS:
Yes! However, any security patches in the new 8.0 boot image will be last outdated until this modified boot is updated if you care about that sort of thing.
[Nexus 6P General] metallicant:
So in other words wait until the op updates the O 4 core boot then?
[Nexus 6P General] SlimSnoopOS:
Entirely up to you. There's no reason to rush into updating.
[Nexus 6P General] metallicant:
I agree.

On to the android O or N?
[Nexus 6P General] dnsh89:
Hey [MENTION=5288606]XCnathan32[/MENTION], just a gentle reminder for the September update of the boot image and EX kernel... We all are glad and waiting for your fix and update.. :good: :fingers-crossed:
[Nexus 6P General] Mad Medik:
Tell the seller you are only buying if it is running pure stock amd you will want to verify that before cash is handed over. They wont want to if it is bootlooping.
[Nexus 6P General] tr1gg3r.man:
Nice work brother man~!
[Nexus 6P General] NoobInToto:
I checked today morning,and the size of the update has reduced to 37.8 mb... Lol
[Nexus 6P General] TheToto318:
Same for me ?

Can i do this update ? (No bootloop ?)
[Nexus 6P General] NoobInToto:
I tried it just to try since it's just 37mb.. then twrp screen popped up and I knew I was doomed :P
[Nexus 6P General] TheToto318:
Bootloop ?
[Nexus 6P General] NoobInToto:
No bro..once boot is modified, the update will not happen in any recovery, let alone twrp

To complete the answer, unmodified stock rom update cannot be done with twrp either
[Nexus 6P General] TheToto318:
Thanks

then I can update with the Google API OTA update zip ?

https://developers.google.com/android/ota
[Nexus 6P General] NoobInToto:
Yeah, that is the only way. But I do not know the procedure.

In the last 2 updates I did (while running the modified boot image), I used the flash-all.bat script with the wipe flag ( -w ) removed and then subsequently flashing the modified boot image. But, I ended up wiping the phone because in both attempts, I got stuck at bootanimation (not bootloop)..and only a wipe would fix it.

Edit: ADB sideload used to work for me during the days when my phone was fine. But I can't access recovery with all cores now.
[Nexus 6P General] GroovyGeek:
Got the BLOD last night, downloaded the N2G48C boot img and flashed. Phone successfully booted and got all the way to the lock screen, but there it crashed with com.androind.phone has stopped and went right back into a reboot. Any suggestions?

BLOD on Oreo with 4 animating dots

I got the BLOD when I had already upgraded to Oreo OTA with Flashfire and had TWRP flashed prior. I tried flashing the Oreo4Cores.img file and it gets past the Google logo, but only to the 4 animating dots. I'm guessing it's related to FDE/FBE? I tried modifying the image source on Github to readd the FBE/FDE flags in fstab and repack the image, but that didn't work either.
[Nexus 6P General] diegz:
Hi guys!

Yesterday my phone suddenly went into what I think is the BLOD...

I can still get into recovery tho (TWRP). I tried flashing SUPERXE rom (clean flash) but still bootlooping.

Is this truly the BLOD? Even if I can enter the TWRP? Is there anything else I can try before this method (i would like not to turn off the BIG cores) ?

Thank you all in advance!
[Nexus 6P General] metallicant:
Can't you just dirty flash the system image with the September security update over the previous O w/August security update, and then re-apply the 4 core boot once that is updated?
[Nexus 6P General] NoobInToto:
Well, flashing the flash-all.bat with wipe flag removed is kinda dirty flash too...

Besides, we need new boot.img for every build(even if new build is just security patch). Atleast, that's the case so far.
[Nexus 6P General] NoobInToto:
Yup, its surely the BLOD in question.
[Nexus 6P General] diegz:
So i flashed the modified ElementalX Kernel (not the 4Core img tho!)...

Now it goes past the white GOOGLE screen but reboot into recovery after the 4 dot color animation finishes...

Can anyone help? :(
[Nexus 6P General] NoobInToto:
This happened to me once in OnePlus 2. Flashing latest twrp fixed it.

I cannot say for sure if that's your case, but I would try flashing latest twrp..
[Nexus 6P General] greyhd:
Its a good time to RMA with Google.
[Nexus 6P General] NoobInToto:
You think we wouldn't do that if we had a chance?

Google will replace your device even if out of warranty IF and ONLY IF the device has been purchased from Google store.

The rest of us who didn't buy from Google store (including me) are screwed by Huawei and this thread is for them.
[Nexus 6P General] diegz:
Ok, solved flashing the 4Core Oreo boot image.

So now we're stucked with only the LITTLE core? So sad...
[Nexus 6P General] greyhd:
I didn't know Google was only replacing devices purchased directly from the Google store.
[Nexus 6P General] NoobInToto:
Well, now you know. Google has learnt its lesson and launched pixel marketing it as ' hardware and software by Google'.

The news you read online of google replacing stuff are devices purchased from Google store. Period.
[Nexus 6P General] greyhd:
Sorry for the double post. I doubt this thread is for only the people who bought their phone outside Google. I also got the blod and tried this mod but it didn't work. Now back to my g2 until pixel 2 comes out.
[Nexus 6P General] NoobInToto:
The fix is for nexus 6p in general, but like I said, google replaces n6p as it acknowledges the bootloop issue (even when the device is out of warranty). I have heard of google rejecting one or two people, but I know that most of them have it replaced.

So, the rest of us have this fix as a godsend, but with performance/battery crippled ( it varies for each of us since it's a hardware issue).
[Nexus 6P General] diegz:
Why battery crippled? I thought it would last a bit more at the cost of the performance.

Holy Guacamole!

[Nexus 6P General] NoobInToto:
It could be that the 8 cores are more power efficient when run together than the smaller 4 cores. Who knows. Anyways battery drain is fast for me, with early shutdown below 15 %.

Performance is a hit and run for me
[Nexus 6P General] vickonix:
Bootloop continues

I'm running Android 8.0, thanks to the fix, I m free of Bootloop once i flash the .img file.

BUT, everytime I restart, the phone goes on a Bootloop again. :(

Is there a fix for this? this was't the case with 7.2.1, please advise.

Thanks in advance
[Nexus 6P General] NoobInToto:
Is it possible that you are using the command fastboot boot Oreo4Cores.img (or something like that)instead of fastboot flash boot Oreo4Cores.img

?

Cuz idk...like for example, fastboot boot recoveryname.img would boot into a recovery for one run. What you say sounds like you booted using the boot.img for one run. Not sure if this thing with boot image is possible though....lol
[Nexus 6P General] T_Squared451:
hello...

I'm trying to get passed the TRWP password to decrypt/mount data. I've followed the procedures here:

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

I've flashed both N2G48B_4Cores.img and twrp3_1_1_4Cores.img per the instructions. I would like to continue on and flash EX4_1_1_4Cores.zip via TWRP (and also root/SuperSU with SuperSU-v2.82-201705271822.zip). So, my understanding is that I need to copy the EX Kernel (and SuperSU) to the phone download directory (via USB). The problem I'm having is that TWRP request a password that I can't get around. I've noted the following in the OP's initial post:

Problem here is once I do the factory reset, then the EX Kernel is blasted from the phone. Sure I can now access the data/file system, but there is nothing there. If you allow the phone/system to reboot then your back to be encrypted.

So what am I missing?

Edit: Figured this out shortly after I posted this. I didn't realize that a USB connection was established with the PC when inside TWRP. Simply had to transfer the files when in TWRP and install.
[Nexus 6P General] GroovyGeek:
Nope, the fastbooot command was OK. I reset to factory and now the phone boots and is alive. However, now I have another problem - can't flash SuperSU. I am using the modified TWRP but SU2.8.2 crashes the phone during intall. Grrr... I am this close to juinking the phone and buying a OnePlus 5

EDIT: re-flashed the modified TWRP just to be sure that I had the right one on there, and now it is asking me for a password. When I enter my device PIN it does not mount data. Anyone know what is going on?
