Okay, so I've been reading XDA for a while now to root my devices and install custom ROMs and its been incredibly helpful. However I have a huge issue with my nexus 6p and can't find a way to solve it.
Here goes....
I bought it of eBay a few months ago and unlocked the boot loader and rooted the phone plus i also installed twrp and made a nandroid backup. I then installed pure nexus rom and the phone was working incredibly well.
Fast forward to this week, I decided I wanted to upgrade to cm13, since I missed the cm theme engine. So I Wiped my device clean using twrp. And installed cm 13 and the gapps then rebooted.
The phone booted perfectly but on the optimising apps screen it would reboot and tell me to enter the password that I originally had on the pure nexus ROM. After doing so it would re optimise the apps but would crash and reboot. It was doing this continuously.
Twrp also asked for this password on every boot before it let me see the main recovery menu.
So then I took the logical next step and decided to wipe the phone clean again using twrp. Seeing as my password seemed to not clear the first time.
After the wipe, I decided to use the original nandroid backup to restore my device as the password thing was still showing up. And cm 13 was still not installing. Neither was pure nexus.
Okay this is where it went downhill. I hit restore and had everything checked. The process was going well but instead of the restore completing and twrp saying it was successful. It crashed halfway and rebooted.
Since then its stuck in a bootloop. Its on the google splash screen and then reboots to the google splash screen continuously. And does not boot to the os.
On another note. The bootloader is still unlocked. The recovery works. And so does adb/fastboot. So I wouldn't consider it hard bricked.
Here's what I've tried so far:
I've used the wugfresh root toolkit to flash stock and unroot the phone. With softbrick checked. Still nothing. Phone boots to the splash screen and then reboots to the splash screen.
I then reflashed twrp 3.0.2-1 . which worked And its not asking for my password anymore.
Again I tried restoring from my nandroid and it crashed midway which makes me think the nandroid backup is/was corrupted causing the issue in the first place?
I've also tried to just restore and Flash twrp again and then install pure nexus ROM. And still nothing?
I can also still mount my phone to the PC and copy and remove files.
On another note I find it interesting that although the ROM is installed. And the storage bar on my PC is partially filled showing that it clearly has a ROM installed. The phone does not have the standard android file system. Just the twrp backup folder and that's it.
I would be honoured if you could help me out here. And get my 6p up and running again.
Thank you . [emoji45]
I would suggest you flash the factory stock system image using fastboot to get your 6P back up and running.
If you don't have the factory image they can be downloaded from here
Extract the factory image then use fastboot to flash
Code:
fastboot flash bootloader C:\angler\images\bootloader-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash radio C:\angler\images\radio-angler-angler-xx.xx.img
fastboot reboot-bootloader
fastboot flash boot C:\angler\images\boot.img
fastboot erase cache
fastboot flash cache C:\angler\images\cache.img
fastboot flash recovery C:\angler\images\recovery.img
fastboot flash system C:\angler\images\system.img
fastboot flash vendor C:\angler\images\vendor.img
Check out this guide which has all the information you need, especially around device encryption and flashing roms. Lastly gaining root is as simple as flashing SuperSU or Phh's SuperUser in TWRP.
I hope that helps, let me know if you get stuck.
Yea just flash stock image I had this happen to me before and flashing stock image fixed it.
Thanks guys. I'm going to read the guide and try it out. Then let you know how it all goes. Fingers crossed it all works

FYI don't backup efs partition with that version of twrp. It's a known issue.
i did not realize that twrp had that issue
And guys, I followed the fastboot process by the letter and although everything worked well. The nexus 6p is still bootlooping on the google splash screen and not going any further. :crying:
What should I do? i've added the cmd window screenshot so you guys can have a look.
Try this thread:

Upgrade to TWRP 3.0.2-2 real quick. You didn't need that guide(in terms of his nandroid) but I am glad it worked. Just need to wipe efs partition using adb commands.
I see. And I have upgraded to the latest twrp so hopefully it doesn't not happen again

Good deal!!! There's a build that's unofficial of 3.0.2-3 that you can also jump onto. The current version 3.0.2-2 has a bug with backups on Android N. There was a comprehensive post that someone made about the issues with the different versions but I cannot find it for the life of me.

Thanks for the heads up!
Title says it all. Fastboot works, flashing works. Even if I try to charge the phone on power off condition, it loops infinitely to splash screen. Tried flashing both custom and official ROMs via fastboot. I don't think this is an emmc problem since I can still format and erase all partitions.
Before all of this, I used the official RR Nougat ROM. Everything works fine until it suddenly bootloops out of thin air.

I have tried to flash via QFIL, but it stopped midway flashing the system and device won't turn on now
I guess it's just me messing up somehow with the cables or something
Thank you anyway mshoaib7!

Try this one. May help u. Extract from official ROM. And flash those things. System IMG is not needed if u have any old backup means. Flash use this. Go to recovery and restore old one.
Bcz system image is large, so sumtyms it fails to flash. That's y I said lrave the system data image flashing and restore the backup.

how to properly revert back from mm or nougat roms to stock kitkat rom?
I was on cm13 by ed300, then I tried to restore nandroid backup of stock kk via twrp
then my phone stuck on boot logo, only fastboot mode works, then flashed twrp and stock kk rom after some attempts.
So what are the steps to successfully revert back to kk? (in case this problem happens again in future)
Hi! Guys I have a problem, which doesn't resemble the BLOD, so here is what has happened. I was running stock android June build on 6p, rooted. And my phone started random reboots. I thought it could be fixed with either stock or custom rom. So I decided to flash AOSPA. I went into twrp but could not flash it, phone rebooted each time. I tried stock images via flash all command as well as manual. No rom worked although I could flash kernel etc. I used The Flash's custom twrp and fixed data and was able to flash rom easily, but it bootlooped on google logo, and rebooted. Now I can flash roms etc but it bootloops. Although Tesla rom did go into bootanimation before bootlooping.
So what can I do? Is it software related? What do you guys say!
PS. I did look into other threads, nothing was similar, although I did try a few mentioned fixes.

Use fastboot to FORMAT system, userdata and cache. Note any errors during the FORMAT process.... and then try flashing a full image from Google using flash-all.bat

I'd say you were squarely in a small group of people who are able to access and fully use Recovery but still boot loop after formatting and installing a clean image. If you've already tried a factory reset from the stock recovery I think you are done. Hardware issue. Replacing the motherboard is a fix, but not economically viable.
I had the same issue formatting data and cache to Ext4 and flashing modified stock ROM fixed. It would boot to Google logo freeze reboot and sometimes get to boot animation freeze and reboot.

Cortex ROM it's flashable stock firmware with extras . Though my symptoms where the same I hope I'm not giving you false hope. Worth a shot though.
The only was I recover my phone without replacing is using https://forum.xda-developers.com/nexus-6p/general/boot-images-bootloop-t3633723 < method from here... but the phone is lag af as it is only running 1 core on stock july build. Good luck for that.
I have the same issue going on. i was trying to flash magisx and suddenly it is stuck in bootloop. i tried flashing stock images and everything. i can access twrp and flash eveything and they are getting flashed fine but still it is stuck on the bootloop.

So have you used fastboot to FORMAT system, userdata and cache? Did each format command complete with no errors?
I seem to have hard bricked my 9T after flashing the MIUI 11 rom from xiaomi.eu. I think culprit is a totally botched/corrupted boot loader and I have no idea how it happened. I've tried reflashing back to stock through stock image .bat files, but no dice. It flashed everything but the device still refuses to boot past the MI screen. If I try to boot into TWRP, my device gets stuck at the TWRP splash screen, no matter which version it is. Does anyone know what I can do or try at this point? Thanks.
So do I, first time I successfully instal first beta v25 miui 11, and than when the v26 comes, stupidly, i flash it from twrp, it tells me that i succeed installing that zip, and than i wipe art and cache and reboot system, but what next i know, my phone brick, i can not instal anyrom, from mi flash tool, or from anywhere. I did everything and still can not fix the problem.
Anyway, you still can enterin TWRP UI, after waiting about 10 to 30 minutes, because after intalling that rom, automatically your data format change from ext4 to f2fs, and twrp will need a lot of time to read your disk.
But, even after doing anything in twrp, still can not make my phone successfully boot into system.
And theres moun I/O error everytime i tried to wipe everything, or fix disk, or change disk format. Everything... and i just dont know what to do anymore.
So may be you can wait patiently until you can entering twrp ui, and please lemme know if you know how to fix this problem

Can you list your steps to fix this? My data and cache partitions are 0kb and i get i/o errors too.
I have persist problems after installing muiu 11 over the los16.
Thinking about relock it and sens it back to aliexpress seller.
@mvha just go into fastboot mode, and flash persist.img from stock fastboot rom,
With command : fastboot flash persist persist.img
Thats all

This makes sense as I remember trying to boot into stock recovery early in the morning. I woke up and it finally booted, but the recovery was in Chinese. I will give 4PDA TWRP about an hour and see what I can do. Thanks.

my ARB is 1 if that matters, how can i fix this please?
So I've tried
flashing recovery
rebooting to recovery
flashing a stock ROM in miflash
Hello,
What did you wipe?
Do you already tried to flash a fastboot rom ?
Edit: sorry read later about miflash; do you wiped the persist partition?

sorry, been too busy with work and missed this. after 48 of brick, I followed farhan20 guide he posted here
the miflash software actually did not work at all for me, i let that run for 30 minutes (way too long) and just unplugged eventually and went thru the guide above. after that was able to get into TWRP and then flash my fav havoc OS. life is good again.
Hopefully this can help anyone stuck in fastboot with a soft brick on their hands
