Stuck at boot animation - Nexus 6P Q&A, Help & Troubleshooting

I do not know if this question has been brought up before, but I am in desperate need of an answer. I recently got my 6P and immediately proceeded to unlock the bootloader and flash TWRP to start loading custom roms. I decided to start use Pure Nexus with it's accompanying gapps package but when I go to reboot the device, I am stuck at the circles boot animation. I decide to try CM13 nightlies and the same problem occurs. After searching online for some time, I realize I needed to flash a SuperSU file from recovery that flashes a custom boot.img. I flash Version 2.66 and restart the device. After 5+ minutes on the boot screen, I decided I am stuck still. What do I need to do, I am unable to boot the device.
Thanks.

I'd use Nexus Root Toolkit to unbrick your phone just so that it is working to start with. Then follow the steps more closely for installing a rom. You'll be doing something wrong, I've had no issues!! Best of luck with this.

hmm I'm not sure. this is happening to me right now as I try to restore my backups... maybe has to do with twrp's system handling/mounting, but I just don't know.

Moto G4 (XT1625 Athene): Android won't boot after flashing TWRP 3.1.0

I flashed TWRP on my Moto G4 after booting the TWRP img using fastboot, and now I can't seem to get Android to start. I can boot into TWRP just fine, but when I try to start Android the phone screen just goes black and the LED USB indicator blinks.
Does anyone know what happened and how / if I can fix it without flashing the stock rom?
try flashing everything from recovery again? Maybe you messed up something, like rooting your rom without knowing it
I managed to get it to boot again by flashing the stock system image, but now there are a few odd bugs and I can't get the Android 7 OTA. Fastboot is giving me issues when I try to follow Motorola's instructions (gyazo.com/38675380995061a98714678c796ba92b, motorola-global-portal.custhelp.com/app/standalone/bootloader/recovery-images) saying that the images aren't signed or are corrupt. I'll try just flashing the image files from TWRP like you said.
The forum won't let me link to websites.
I had the same boot problem after trying to systemless root after 7.0 updateon twrp 3.1. Had to reflash to stock recovery and stock boot image before it would boot to anything other than fastboot or a blank screen.
So it seems like the best solution for now is to not flash twrp as recovery when running Android 7 and just booting into twrp temporarily with
Code:
fastboot boot <twrp.img file>
I didn't have any problems systemless rooting my Android 7 phone with supersu doing it this way, the problem only started after I attempted to flash twrp as my recovery.
After flashing the stock firmware, my only issue now is not getting the OTA, which is very frustrating as I had it working earlier today.
EDIT; Found a possible solution for getting the OTA for XT1625 in another thread, flash XT1625-XT1644_ATHENE-RETUS_MPJ24.139-49_cid50_subsidy-DEFAULT_CFC.xml.zip to the phone from here firmware.center/firmware/Motorola/Moto%20G4%20%28Plus%29/Stock/
* Currently testing this now, not sure if it'll work
EDIT; Worked for me, a few seconds after booting I got the OTA update. I'm on Moto G4 (XT1625 Athene) retusa
If you want to know how to flash the .49 rom, refer to this thread (forum.xda-developers.com/moto-g4/development/unbrick-hard-bricked-moto-g4-amazon-t3486578) and follow the instructions as closely as you can. There are some differences between the Amazon version and the non Amazon.
IMPORTANT: do not attempt to systemless root (at least with SuperSu 2.79 SR3), it just caused Android to not boot. For now, wait for a fix. (But if you simply must attempt a root, make a backup in twrp)
Good luck!

Help recovering device

I'd like to give this Nuclear ROM a try. My device is bootloader unlocked and currently has no OS on it. My device was rooted and last thing I tried doing with it was installing the recent stock Nougat release. Reading that one thread I never went through the steps of restoring what was needed I believe in step two to be able to put stock Nougat on it.
I don't care about stock anymore and will try out this ROM. Holding Power and Volume Down I can get to the options for recovery mode/etc. When I select recovery mode the device reboots and sits at the bootloader unlocked screen. Regardless of which option I select the device reboots and sits at the bootloader unlocked screen. If it's bricked so be it. If it can be restored can anyone point to a thread or have any suggestions?
Flash full stock Nougat:
https://forum.xda-developers.com/moto-x-style/general/guide-flashing-stock-firmware-t3637235
Files for fastboot you have to find:
https://forum.xda-developers.com/moto-x-style/general/page1
After one boot you can flash twrp & custom rom, f.e. Nuclear. @lip008
Thanks. I just needed a refresher. Everything for fast boot was installed and TWRP was still in the folder. For some reason i thought i was worse off than i was.
Back up and running with this NucleaROM. I may retire the s8+ and go back to this as my DD.

[Bootloop] N9005 not booting after frame (display) replacement

Hi,
as the title says, my phone is not booting anymore, after I transplanted the motherboard from a frame with a broken screen into a new frame (from china).
Abbreviations used:
RR => Resurrection Remix 5.8.5
CWM => ClockWorkMod Recovery 6.0.4.6-kitkat
TWRP => TeamWinRecoveryProject 3.2.1-1
I was using RR from the Rock Stable Setup on it before and it worked beautifully.
What happened:
I performed the mainboard-transplantation according to the iFixit guide
I held the power button to boot the phone:
It vibrated
It showed this screen for a couple of seconds
It vibrated
Back to step 1
And that until I removed power.
Then I tried to boot into recovery mode by holding the key combination on boot:
Same as above, but with this bootscreen
Then I tried to boot into download mode by holding the key combination on boot:
The warning to confirm download mode poped up and I got to see this screen.
I connected it to my PC and opened odin 3.09 and it recognized the device.
I tried to get adb and fastboot to see the device, but nothing worked. (In the old frame and before I broke the screen, it would be recognized at this stage)
I flashed TWRP with odin, odin showed the green "PASS!", but booting to recovery still failed.
I proceeded to flash a stock ROM, which had worked when I had issues with RR.
It worked, I went through the Android 5 setup process, enabled debug and connected adb.
adb saw the phone.
I rebooted to recovery and stock recovery booted correctly.
Sideloading anything with adb failed due to signature verification.
I then went back to download mode and flashed CWM successfully.
It now boots into recovery, but whenever I try to flash anything with CWM, it fails showing this screen
Or something similar (the photo comes from flashing RR 5.8.5)
I have both linux and windows properly setup and used both with adb, fastboot and odin (only windows)/heimdal (only linux).
I checked drivers and usb cables.
I opened the phone back up and checked all connections.
But I can't get any version of RR, CyanogenMod or LineageOS on there.
I've searched the internet, but people that have these kinds of problems after replacing parts of their phones, seem to only have driver issues or skipped steps in the manuals of custom ROM installations.
If you have any idea on what I could try or what I'm doing wrong or not doing, please leave an answer.
I'll keep this post updated below here:
(no updates, yet)
Thanks so much in advance
Simon
Your picture shows stock recovery not CWM .
Try flashing TWRP recovery through Odin .
I did flash TWRP and afterwards there was no recovery anymore.
When I flash CWM, I get the recovery shown in the photo.
The stock recovery has a black background and no touch controls for me.
What you saw must have been CWM.
Update: I can flash twrp-2.8.7.0-hlte-4.4.img.tar and it works. It's the only image that works, but I still can't boot into or flash any custom OS.
The only working OS I have at the moment is a stock android 5.0, which is not all that useful...
If anyone has an idea, why I can't or how I can find out what is causing it, please say so.

What do you mean by ANY ??
Well, exactly that.
Regardless of what zip I flash, I end up with a bootloop.
If I flash a recovery zip, the recovery bootloops, but the OS still boots.
If I flash a custom ROM, I can still boot into recovery fine, but booting normally results in a bootloop.
The only way to get software onto my phone has been via odin and only an old CWM, Philz Touch, TWRP (Version 2.8.7.0 and below) and STOCK Android (Versions 4.3, 4.4.2, 5).
Anything else I have tried so far did not result in an error, but I couldn't boot into it either.
If you have ideas for software I can try flashing, please tell. I really have no idea how to get the damn thing to work again...
What happens when you flash correct stock rom via Odin ??
I mean that I can boot into it after flashing it via Odin.
But its terribly slow and bloated compared to ROMs like ResurectionRemix, so I don't want to use it.

In that case phone is OK .
Usual is that user is failing to follow instructions .
Not sure what you mean by fastboot on a N9005 .sounds like not a N9005 .
Personally with TWRP 2.8.70 i would be flashing something like .
https://forum.xda-developers.com/galaxy-note-3/development/rom-magma-nx-rom-t3508672
as its correct TWRP .
I am able to follow instructions.
Thank you very much.
I followed exactly the same procedure that has worked many times when switching between custom ROMs.
Also, the phone has a perfectly working version of Ressurection Remix installed at the time my frame broke and it did get stuck in the same bootloop after replacing the frame, even thogh the software was exactly the same.
I am looking for help analyzing the boot process and some way of capturing the kernel log when booting to determine where the error occures that traps the phone in a bootloop.

Dear Mate..
Have you solved your problem? I have same problem after transplating N900 frame.
Sorry, I gave up, since I dearly needed a working phone and bought a OnePlus 3 cheaply from ebay second hand. It's been working like a charm and I threw the note into my museum after I softbricked it for the n-th time and couldn't get it out of a bootloop that didn't leave me time to go into Fastboot.
Sorry friend, but I can't help with this.
after reading a lot of similar threads, seems like the hardware is the cause of us not able to update to higher versions of twrp(& custom roms)

Lenovo tab 4 10 Plus TB-X704V loop reboots

After failing with installing different versions of TWRP om my tablet (There is no working version on TWRP for my model- system revert itself to the Stock recovery mode), at some point I noticed, that I can power on tablet and get to Welcome screen and start tablet configuration, but right after 20th seconds system freezes for few seconds and reboots over and over. If I just power on system and let it stay without touching screen it will reboots after 20 second.
If I go to the Recovery mode, there is not reboots. I did system hard reset in Recovery mode no help.
I thought it is problem with ROM, and flashed Stock Rom with Lenovo MOTO Smart Assistant. Same issue with reboots, then I tried some other ROM’s regions with same issue. Before I got this issue, other ROM’s used to work just fine.
QUALCOMM flash utility did not help as well.
I am just interesting is this issue with System board or it is software issue and I can fix this.
I have the same issue. I have been able to root through a patched boot image, but cannot get recovery to flash no matter what. It says all went successfully, but then always reboots. I have the 2GB version.
I just want to install an updated ROM since lenovo abandoned our devices.

I've just spent days trying to get my TB-X704V to flash. I finally found out how. The issue I ran into is the recovery mode never worked. I found one that did. Big caveat here. Once I flashed the recovery image, I could no longer boot the stock rom.
I found the recovery image looking for X704A, and ended up with the files at https://drive.google.com/file/d/1QyUGBPi-KZrhSVFLOCs3lHUZ59fpe9KL/view (not my files). This is Chinese/English version. You can change language in the menu.
Follow the directions on flashing it at the quick boot menu and unplug and go into recovery mode.
Download the latest lineage OS: https://androidfilehost.com/?fid=6006931924117916469
Install the OS. The initial boot will take a few minutes, but it will boot.

Thank you so much, I was able to boot straight into TWRP using that Chinese/English image. I spent days last week unsuccessfully trying to boot my TB-X704V into the twrp-3.2.3-0-tb_x704l.img recovery image, but it never took no matter what I tried.

Boot loop after rooting with Magisk

I am puzzled by what's happening...
We got a new Moto G7 for my wife and following the instructions here https://www.the***********.com/install-twrp-root-moto-g7-plus-guide/, I successfully rooted the phone. However, there was a security update that needed to be installed, so with some great advice from ptn107, see https://forum.xda-developers.com/mo...-trying-to-t3977463/post80429619#post80429619, I flashed the updated ROM onto the phone. (Note that I omitted 'fastboot erase userdata'. Also note that the warning message 'is-logical:<partition>: not found' was seen for all flash commands.)
The phone booted properly after the update, so I then went through the exact same rooting steps that had worked previously. However, this time, the phone gets stuck in a boot loop. I reflashed the ROM and can boot successfully, but the phone is no longer rooted. (I have tried this twice, with Magisk 19.3 and 19.4 - same result.)
Any ideas as to what I may be doing incorrectly? More importantly, what is the best way forward?
Thanks.
im dealing with the same issue. you can flash TWRP and go to advanced, fix boot loop, and that should get it to boot, but then you lose Magisk. May be a verity / checksum issue with the stock ROM. probably an easy fix but I dont have it.
EDIT: also you can flash the stock boot.img back and that will do the same thing, but again you lose Magisk/Root.
