TWRP bootloops

I've seen this problem mentioned in a few threads but not seen any definitive fix.
My current install :
Stock NPD35K system, vendor, bootloader
Xceede's v8.01 kernel
TWRP 3.02 v6.0
Encrypted data partition
I currently get bootloops every time I boot into TWRP. After using TWRP and attempting to reboot it will then bootloop into recovery refusing to boot the system.
I have found it can be fixed by rebooting into fastboot and the "fastboot reboot" command. But this is frustrating if I don't have a laptop handy.
This happens every time I need to boot into recovery to install or update via TWRP. Is anyone else getting the same bootloops and has anyone found a permanent fix?
Thanks guys.

Hi Jake,
I had exactly the same issue since NPD35K except the fastboot reboot solution did not work for me.
What i could find was that if you flash the default vendor, recovery and cache partition via fastboot and then put off the tablet, it should after all of this boot correctly to the system.
Cheers,
Mathieu

You are not alone ..
I had the recovery bootloop once myself.
I did the "fastboot reboot" command and since then the Pixel C is booting fine again.
Did several installations afterwards .. no problems anymore.
Just once ..
But if you get it every reboot this a real problem.
Right now I am not able to help you .. just don't know the root cause and how to fix it.
As it looks like, it helps if you go back to stock recovery, like mentioned above.
I can not confirm this .. as I don't have the problem.
Good luck !

Thanks for the advice guys.
As I said it only bootloops immediately after boating into TWRP (even if I don't install anything), if I reboot from system it's fine.
At the moment I prefer to keep TWRP installed and reboot from fastboot if I need to use TWRP. I don't see an advantage to installing the stock recovery. It would be great to pinpoint what's causing this though.

I'm still getting this TWRP bootloop. I've tried several versions - 3.0.0, 3.0.21, 3.0.23. I've tried numerous times re-flashing stock using NRT and then flashing the recovery again. I've also tried fastboot-reboot.
I'm on stock 7.1.1 - NMF26H. If i need to install a different version for this to work I can do that.
Is there perhaps some particular version of TWRP that everyone but me is using? Or are there some specific versions of other files that I also need to flash along with TWRP? From what I've read if I get past this once that's probably it.
Thanks

Pls install latest bootloader and latest factory image via fastboot, manually.
Pls use latest fastboot binaries from Google.
Pls install 3.0.2-23 via fastboot as well.
Reboot directly into TWRP and not into system in between.
Install SuperSu.zip v2.79 in TWRP.
Reboot into system.
The first time the system will boot twice .. it's normal.

Thank you. I'll try this today. If I use s tool like NRT to flash "stock" to the device, does that cover what's described in the first step - latest bootloader and latest factory image - or is there something else I need to flash at that step?
Thanks

Maybe your problem is related to the tool itself
For this reason I recommend to use the official google fastboot tool for complete flashing of factory image including bootloader.
To have a proper base to continue ..
Good luck !
EDIT: .. no need to wipe data here. Just a fresh system, vendor, cache and boot image from factory image.

I think that answers my question - the original factory image including the bootloader.
I'll try it in a few hours. Thank you very much!

That worked! I was currently on stock 7.1.1 so I tried it first without re-flashing, although I was prepared to go back to that step if it didn't work.
First I downloaded SuperSU 2.79 and copied the ZIP to my device.
I used Minimal ADB and Fastboot (which I think is taken from the official Google source) and flashed recovery-twrp-3.0.2.23.followmsi-ryu.img.
Then I rebooted into recovery - not system - and flashed SuperSU.
Finally I rebooted into system.
The Google logo appeared for a moment and then it booted again (exactly as you said.) Then it booted normally.
Finally! Thank you very much! Hopefully this will help someone else too. It can be the smallest detail we miss that makes the difference.

tried numerous times to flash TWRP to my Pixel C 8.0.0 (OPR1.170623.032, Nov 2017) every time with bootloop in to recovery...
most recently hoping twrp-3.2.0-0-dragon would work
---------- Post added at 07:44 PM ---------- Previous post was at 07:29 PM ----------
tried to reflash ryu-opr1.170623.032-factory-020f1cf9's boot.img and it still bootlooped.
Tried to flash the recovery and now its bootlooping into stock recovery. Any ideas?
for a stock google device, this things a nightmare to work with compared to my nexus devices

G8 Stuck in twrp loop

This is the first time I've ever done this, but I just hated the UI on the Huawei G8 (laggy) and decided to try the xda way. PS: knowing that it's easier to help someone when they tell all the details, I am going to post all of it. So sorry for the long post.
First thing I did was try to update to unofficial marshmallow downloaded from here. But it didn't work saying installation failed ... Did some research and found out the device OS is from Iran (I'm from the middle east), so probably the reason why it didn't allow me to install an EU update.
What I did then was unlock bootloader by getting the unlock code from emui website. And then unlocking it from the adb terminal (adb.exe)
Then I loaded TWRP and did a backup.
I forgot to copy SuperSu to the SD card, and when TWRP asked me to root I accepted. So it got stuck on the Huawei logo while booting.
I then did a recovery from TWRP which worked perfectly
I should've just downloaded a new rom and flashed that , but I was like maybe it might allow me to install that update now the phone is unlocked so I tried installing it from the updater ->local update. And that's when the looping into recovery happened.
So I tried to do another recovery from my backup , but again it loaded into TWRP . Which I don't understand since I guess it should load the backed up System. Or is there something telling the device to reload the update from the SD card causing it to crash again ?
UPDATE: I went into file manager and renamed the dload folder to dloadxxx but that didnt help. Then I downloaded the latest TWRP and flashed that, and recovered the backed up system and THAT worked . The restore took longer than with the older TWRP . I have no clue why it worked like this. But maybe this can help someone in the future.
Thanks

Had the same thing. Exept that this happend during OTA update ....
Get a stock ROM of your choice (tested with xxxB130xxx).
Use update extractor to extract boot.img, system.img recovery.img
Wipe all partitions (except external SD Card) with TWRP. Select remove data and confirm. (you said you have backup). This allows a clean install.
Bring phone into fastboot mode (Vol down + power)
Flash bootlader with fastboot
Make Reset
Flash recovery and system
After reboot phone should start up normal.
Let me know if you got stuck somewhere.
Chilli
Edit: Root cause for the problem seems that Hauwei needs stock recovery for some update actions. -> When ever you want to make OTA or dload update flash back to stock recovery before (better flash completely to stock ).

h t t ps://mega.nz/#!P04D2S5Y!Yn2CL5wLC8ISb5AcNR9MTxzhAq3yVH3weG60go5zQCA download this archive, change twrp inside it with the lastest one that surdu_pertu provide.
go twrp wipe all things there
than
using adb "fastboot flash recovery stock.img"
after the first boot phone gonna think a new firmware is being installed just skip it and power off the phone
this will give you a nice start for flashing the Marshmallow from the begining.

Hello Demage,
I would be looking forward to having an Marshmallow image (if it supports my basebands). But Mega says the key is invalid. Can you double check?
Chilli

Thankfully, I managed to fix it.
1- Download Marshmallow G8 stock ROM.
2- Download Huawei update extractor, then extract recovery.img using the previous tool from the stock ROM Update.app file.
3- Go to the bootloader, then flash the extracted recovery.img into recovery.
4- Reboot by the command fastboot reboot.
5- You will get the default loading screen saying the device is reset, then you will be directed to the system welcome screen.
6- You can flash TWRP again, then superSU.

Issues on top of issues rooting Pixel 2 XL! Help? :(

First, I followed a tutorial precisely and ended up with a bootloop. It was just stuck at the white screen with a G. This was only after flashing the patched_boot.img file that Magisk gave me. I searched for hours online for an answer for that, and my device isn't listed when I type "adb devices." It's just blank. I uninstalled and reinstalled the drivers, I used different usb ports, different cables, I'm using the latest Google usb drivers, as well as the latest adb/fastboot files.
I wanted to push twrp to my phone via ADB, so I can flash magisk that way and fix this issue. I've read that it fixed my problem for other people, but sadly I'm unable to so far. When I try using the command "adb push twrp.zip /sdcard/" I get the following error:
"adb: error: failed to get feature set: no devices/emulators found"
In case anyone was wondering this is the tutorial I initially followed: https://youtu.be/M-0NIUUvYI4
I really don't know where to go from here. I've been looking around for 6 hours straight. All help is most appreciated.

Fastboot boot the twrp img file, then once you're in twrp, adb push the twrp zip file, and the stock boot image (extract it from whatever security update you're on). Then, adb push the magisk zip file (instead of a patched boot image) and download and adb push a custom kernel as well.
Flash the stock boot img, then twrp zip, then a custom kernel to retain touch functionality within twrp (I recommend flash kernel) and finally flash the magisk zip file and once you reboot, you should be good to go.

Thanks for the response, Ricky. I tried using the ADB sideload feature in TWRP but it just stuck at "Starting ADB sideload feature..." and eventually fails. Then I used a flash drive and connected it to the phone via the adapter, and that worked. Unfortunately, after flashing those files it was still stuck at the same bootloop screen. I went back to TWRP and now the usb flash drive isn't being recognized. What should I do?
Edit: I was able to FINALLY get it out of the bootloop! I tried this script earlier and it didn't work, but it was because I didn't have the critical partitions unlocked (https://forum.xda-developers.com/pixel-2/development/tool-deuces-bootloop-recovery-flashing-t3725778). Unlocked them, ran the script, works perfectly now. However, now I'm going to root it via TWRP and use the files you mentioned. Will do that tomorrow after sleep!

If your going the OTA route, which, personally, I wouldn't if your bootloader is "fully" unlocked, you'll need to completely unroot, and return back to stock recovery. Not trying to deter you, I just think that fastbooting the monthly factory images is much easier, with fewer chances for errors. Not to mention, if you know the proper technique, you won't lose any data :good:

Hey I'm not exactly sure which factory image I should choose. When I was rooting the phone the tutorial said to use the image with the same build number. My current build number is "OPM1.171019.018, Feb 2018", and I'm assuming what I should do is use this one "OPM2.171019.029, Apr 2018"?

Help Updating to December Security Patch

I'm running the stock rom on the November patch. I have TWRP installed with Magisk and the Kirisakura kernel. I've read and Googled for a solution and still can't get it to work. I have the latest ADB told installed but I am unable to push the update through. Can someone tell me what I'm missing? This used to be so much simpler lol. Thanks in advance.

From what I understand you can not do ADB in TWRP to install an update. What I did was download the factory images, remove -w from the flash all.bat. flashed the images and let the phone boot normally. Once I knew it was running I went to the bootloader and booted TWRP temporarily. Once that was up I flashed Magisk and then my kernel
I don't install TWRP anymore.

Adding to what hatdrc said, you want the full image, not OTA, and install from your PC in fastboot mode. If you are concerned about saving your data, remove the -w switch from flash-all.bat first using a file editor like notepad. Have the twrp.zip, kernel.zip and magisk.zip files already staged. I personally don't boot to system first (but you can), I "catch" the reboot after flashing completes with the volume down button to reboot to fastboot mode. Then fastboot boot twrp.img, and then install twrp, kernel and magisk zips all in one go using the "add more zips" button in twrp. Every month when you update, you'll lose twrp, kernel and magisk, so those have to be reflashed each time. You'll soon get used to it and can do the whole thing in about 5 minutes consistently. Just make sure to pre-stage the 3 zip files on the phone before you start. Best of luck.

I tried that but couldn't get it to work. I downloaded the ADB tools again just in case there was an issue with that. I'm going to run the flash-all script again to see if I can get it to work.

if whats suggested above doesnt work, you can make the OTA work....download the ota to your PC, boot to Android Recovery (not TWRP), apply the ota via ADB from the menu. Whenever I have "odd" issues applying the Full image, this always works for me. Obviously you need to re-root after.

Unable to flash OTA update

Hi all, I have TWRP + Magisk on my device and I am attempting to update from PQ1A.181205.006 to PQ2A.190205.001.
Steps taken
1. Downloaded the OTA from here: https://developers.google.com/android/ota#crosshatch
2. Moved the OTA to phone storage.
3. Checked SHA256 checksum matches.
4.
Code:
adb reboot recovery
5.
Code:
fastboot boot twrp-3.2.3-3-crosshatch.img
6. From TWRP > Install > OTA zip file
Fails with the attached error. I have also tried sideloading through TWRP with the same result. Has anyone hit this error or successfully flashed the OTA update through TWRP?

I have not heard of anyone successfully loading an OTA through TWRP. Either restore stock recovery (install boot.img to both slots) and sideload with the Google instructions or run the flash-all (remove the -w) to use the factory image. Either way, you ere going to be reverting to stock recovery.
P.S. Your message doesn't make sense since you say you have TWRP on your device but then are showing that you used fastboot boot to run the TWRP .img file. If TWRP was on your device, you wouldn't have to use that command. You would just have entered TWRP with the adb reboot recovery command. I am guessing you are rebooting into the bootloader screen where either you run the TWRP .img or run the flash-all.

I also thought I saw a previous post somewhere that said you cannot skip an update, so going from December to February may not work.....not sure...
But definitely you need to load the OTA via regular Recovery using adb not TWRP....

Can you install a OTA?
I thought you had to perform an ADB sideload of an OTA.
Even then I am not aware that ADB sideload works for Pixel 3xl yet.
I have been flashing the factory image with -w removed.

ADB sideload works fine for the OTAs in stock recovery. That's how I've been doing mine.
On a side note, the Essential phone is the only phone I've come across so far that TWRP will flash the factory OTAs.

Flash them or sideload them? I never had a P2XL, but I had a Nexus 6p and I don't remember being able to flash that with the factory zips. That doesn't mean my memory isn't shot either.

Did you first extract the secondary zip file inside the factory image, and then placed the boot.img in your platform-tools folder, and the used the command..fastboot flash boot boot.img....??

Fails with the attached error. I have also tried sideloading through TWRP with the same result. Has anyone hit this error or successfully flashed the OTA update through TWRP?

I've installed 3 latest updates from twrp ...
Download the latest OTA, you have to be in stock Rom and Kernel stock ... and have last twrp on your phone... Flash OTA and twrp installer to keep twrp ... restart in twrp for magisk or restart system ... benefits
sorry for my bad english.

Tap install on the twrp home screen. Then go to where you have the boot.img on your internal storage and tap image on the bottom right. Then select the "boot" partition, and swipe to install. This will return you back to stock recovery and kernel :good:

Well I managed to do that, but now when my phone rebooted the touch screen no longer responds. Very strange. It all loads fine and I can see my screen but nothing works. I tried to go back into recovery and I get the little dead Android guy laying on his back with a red exclamation point and "No Command" below it.
Any ideas?
