Updated TWRP, now system only boots back into TWRP

I updated TWRP in TWRP via zip flashing and now whenever I try to reboot my phone, it only boots back into TWRP.
Previously, I was unlocked bootloader and rooted on stock.
Would appreciate any help. Thanks

I've never installed TWRP on this phone, but here is one thread Google returns that seems to be similar.
https://forum.xda-developers.com/pixel-xl/how-to/twrp-bootloop-flashing-twrp-t3533765
One relevant thing that has changed since the time of that discussion is that the May and newer bootloaders require a signed boot image. When I installed the May update with SuperSU without signing the boot image my phone simply ended up switching to the other slot, but again I didn't have TWRP installed. There is a zip for signing the boot image and further discussion here.

Thanks for the response. Looks like I have to flash factory image and then the verified boot signer. I'll give it a shot and report back.
Fixed this rather easily using the June factory images. Flashed using flash-all.bat (and removed the -w) and things are updated and back to square one. Interestingly, I didn't need to sign the boot image.
Thanks for the help.

Do you need to use the signed boot image file if you are flashing an unrooted custom Rom? I thought you needed to use it when flashing anything that changed the boot image from stock, including flashing TWRP if it's going to be installed on the phone.
Actually now that I thought about it the signed boot image is SuperSu specific, isn't it?

My understanding is that at the last step before restarting the phone the boot image needs to be signed, if the bootloader has been updated to May or later. The stock image is signed, and I've read that ElementalX will also sign the boot image. If you install anything else at this time, such as TWRP or SuperSU or Magisk, then I think as the last step it's necessary to also sign the image. Now that you've updated the bootloader, my understanding is that you will need to sign the boot image if you install TWRP again.

So, I just ran into this issue with my Pixel 2 XL when I tried to update my TWRP version from 3.2.1-2 to 3.2.3-0. Here's how it went:
1. Downloaded the TWRP zip, md5 and so on from the official TWRP website for the Pixel 2 XL
2. Booted to TWRP and installed / flashed the zip of TWRP 3.2.3-0
3. Wiped dalvik and then chose Reboot to System from TWRP -- the phone booted right back into TWRP
4. Tried again to reboot the same way. Same result.
5. Installed / Flashed the 3.2.1-2 TWRP zip which was still on my phone, in order to revert to the previous version, and then Rebooted to System -- same result
6. Flashed 3.2.3-0 zip again, then flashed the Flash Kernel that I've been using, and then Flashed the Magisk v16.0 zip that I used to root, then chose Reboot to System -- AND IT WORKED; the phone booted normally and now I'm updated to the latest TWRP successfully.
tl;dr - The solution is to flash Magisk again after updating TWRP. Pretty sure this goes for kernel updates too.

Clean Wipe and Install of Jan 18 Release Won't Boot with Magisk 15.2 (1520)

Every time a new image comes out I wipe the device and flash the new release image using the flash-all.bat. However, this time I'm running into the issue of just trying to install Magisk beta 15.2 because it won't let the device boot. I've tried two methods:
Without Installing TWRP
1.) Wipe phone (factory data reset), flash-all.bat, and set-up device to get pin and fingerprint setup
2.) Reboot to fastboot and fastboot flash boot twrp-3.2.1-0-marlin.img
3.) Boot from fastboot screen into recovery and flash Magisk beta 15.2 (1520)
4.) Reboot to system and won't pass G logo
Installing TWRP
1.) Wipe phone (factory data reset), flash-all.bat, and set-up device to get pin and fingerprint setup
2.) Reboot to fastboot and fastboot flash boot twrp-3.2.1-0-marlin.img
3.) Boot from fastboot screen into recovery and flash TWRP-installer-3.2.1-0.zip
4.) Reboot to full TWRP recovery
5.) Flash Magisk 15.2 (1520)
6.) Reboot to system and will not boot past G Logo
The only thing I am trying to accomplish is get Magisk working with the stock kernel; I don't care if TWRP is installed or not. Someone else has to have tried this or has to have seen this issue because nothing I do short of restoring stock boot will allow it to boot up. Anyone have this issue and know how to get around it using the Jan 18 software?

i think the problem is that you're flashing the twrp image with fastboot instead of booting it. in #2 for either method that you tried, you ran fastboot flash boot twrp-3.2.1-0-marlin.img. try it without the word flash. fastboot flash boot twrp-3.2.1-0-marlin.img. the twrp web page for the pixel xl recommends this as the way to initially run twrp. fastboot flash boot changes the boot image. fastboot boot doesn't. when you flash the magisk zip or twrp zip from recovery, they're expecting the stock boot image. but since you ran fastboot flash boot, the boot image was modified and no longer stock. that's about all i understand about the pixel's partitioning and the boot image. there are others who can explain it better than me.

I definitely missed that and I actually know exactly what you mean by not using the "flash" term. I'm going to give this another shot, thank you for pointing out my mistake I definitely see the issue now. :good:
Edit: That was exactly it. Booting directly to twrp fixed my issue because I was modifying my boot partition every time I flashed twrp. My own worst enemy. Thanks for helping me out @altwu

no problem. glad to hear that you're up and running.

[SOLVED] HELP! i'm stuck in a boot loop! :(

my flashing history:
i was on audax (oos based nougat rom) with blu spark kernel before, then went to official ob1, then back to audax, then back to stock oos nougat and now i flashed audax and after clean flashing it, it just wont boot up.
when i try to boot up i see the 1+ logo but then it reboots to recovery. i also tried flashing stock nougat again and also flashed stock kernel manually but it also doesnt work.
i always do:
1. wipe system/dalvic/cache/data
2. install ROM
3. wipe dalvik/cache
4. flash magisk (also tried without flashing magisk)
5. reboot
i've been looking on the interwebs all day but nothing worked.. help pls :/
EDIT: problem was blu spark twrp. Maybe installing Oreo ****ed it up. I flashed codeworkx newest twrp universal build and now Im able to boot again!! Btw: I also found that magisk 15.0 prohibits a proper boot up and results in a boot loop. version 15.2, however, does the trick!

when it auto reboot to recovery, formate data

When s**t happens, it is wise to start everything from scratch:
-boot in fastboot mode and flash stock recovery with "fastboot flash recovery recovery.img" (rename recovery.img with your recovery filename), then reboot recovery and select english, advanced, adb sideload;
-flash stock OS with "adb sideload rom.zip" (rename rom.zip with your Oxygen OS filename).
Procedure will require some minute because of the large file size. Remember to save all your data on internal storage first!
I advice you to flash original recovery because often sideloading in TWRP leads to some error.
Your phone will boot again... after that you may reflash TWRP, Magisk etc

I had the same issue. Bootloop and jumb into recovery by itself. You have to flash magisk 15.2 via recovery and will be boot.

He says that it occurs even without Magisk... I had a similar trouble once, and the only way to solve it was the procedure I wrote above...

I dont know if you can boot it w/o root

All the usual preemptive steps are complete, correct? You OEM unlocked it and all that?

Don't feel too bad my friend, the P2XL is a quirky little bugger to say the least. I had a heck of a time rooting 9.0 after I updated from 8.1, then outa the blue, it worked. Here's a few steps to try.
1. Fastboot twrp, then flash magisk, try to boot.
2. Fastboot twrp, flash twrp.zip, boot up, then go back to twrp and flash magisk. If no go, do the same steps, except after you flash magisk, flash the magisk uninstaller zip, then flash magisk again.
3. Fastboot into twrp, flash twrp.zip, custom kernel.zip, then magisk.zip. if no go, then try the magisk uninstaller.zip method again.
4. Stick with it, be patient, sooner or latter you'll find the right combo. Also, it seems easier to root using a custom kernel, if your willing to try it :good:

Maybe give the guide linked in my sig a shot.
If that doesn't help, try the following:
-once you've permanently installed TWRP, try rebooting to recovery after each additional step BEFORE rebooting to system:
install cust kernel, reboot to recovery, reboot to system
install magisk, reboot to recovery, reboot to system
if that doesn't work, try doing a mass install after TWRP is permanently installed:
in the same flash, install cust kernel and magisk, reboot to system
These have helped other users who have had odd issues with their set ups, but in the end, Pixel 2 XL is a fickle beast
Best of luck!

SOLVED
The only way (for me) to root my Pixel 2 XL is follow theese steps:
Rooting with Magisk
NOTE #4: This section assumes you are not going to install TWRP. If you are, skip to the next section and just flash the latest Magisk zip after installing TWRP.
Download the Magisk zip from the official thread and install the manager from the zip.
Grab a boot image to patch (either the one from the latest factory image or a custom kernel one) and push it to your device:
Code:
adb push <path_to_file> /sdcard/Download
Open Magisk Manager and click the Install button.
Click "Install" at the first prompt then choose "Patch Boot Image File". A file manager will pop up.
Select the boot image you want to patch and let Magisk Manager patch it.
Pull it off your device:
Code:
adb pull /sdcard/MagiskManager/patched_boot.img
Reboot into the bootloader:
Code:
adb reboot bootloader
Flash the boot image and reboot.
Code:
fastboot flash boot patched_boot.img
fastboot reboot
Open Magisk Manager and you should be rooted!

After trying to root with Magisk...

After I tried rooting with magisk, Pixel 2XL, 11.0.0 (RP1A.200720.009) And I flashed the patched .img file from magisk, My phone then right there got into a bootloop, I was able to get into the bootloader but nothing else, Now I cant get out of the bootloader and im wondering if there is someway to fix this, I saw a thread on this, Which says I have to change Magisk Manager to Canary but I cant because im stuck in a bootloop AND im in the bootloader, I already unrooted my drive by Flashing the original img but no help...
Any help?

If you flashed a patched img, then flashing back an unpatched boot.img would fix it. You can always download the the full factory image and flash it back.

if you reflash the factory boot.img then you'll get out of bootloop.

reflashing the factory boot.img seems useless. you can long-press the power button to force power down. then power up to the fastboot mode,and reflash the full factory image(11 or 10). the nomal methon working on 10 seems dizzy in 11 now.

fwiw, heres the path i used...i hate making it more steps than needed (tranferring boot image to device and back again for magisk patching for example)...
1) flash-all.bat (with wipe enabled - because clean install)
2) Immediately on reboot from 1 and before it gets anywhere near to beginning of setup: fastboot boot twrp-3.4.0-1-taimen.img
3) adb push Magisk-e66b0bf3(20425).zip /tmp
4) adb shell twrp install /tmp/Magisk-e66b0bf3(20425).zip
5) adb reboot
6) after reboot, install canary magisk manager (for whatever reason doesnt install from TWRP flash)
7) open canary magisk manager and enable magiskhide

This is caused by twrp
Use android toolbox, just boot twrp, flash magisk

boot into twrp go to advanced fix bootloop option reboot
