[Fixed] Installed Magisk V20 and i lost TWRP

Ive tried uninstalling magisk using the un-installer and no go. Ive tried booting into twrp then flashing the twrp zip then rebooting into recovery and it goes to the stock recovery. How do i get back TWRP?? Im on Pie and was using twrp .65
NVM: I had to re-flash 9.5.11 then twrp then reboot then magisk 19.4
I am in your same situation oneplus7.
Currently I was with twrp 3.3.1.1 but there is no way to catch any recovery. By flashing the image either version 1/65/70 (more current) by fastboot it enters correctly img you access twrp to later flash the zip But it never gets installed.
I tried to uninstall using img twrp Magisk zip uninstaller and install the 19.3 / 20v uninstall it completely and flash back to zip twrp but I am in a dead end.
Right now I am with Magisk v20 root edxposed and everything goes phenomenally as a result that I am going to "peel" without having twrp for my backups or anything.
Anyone have any idea how to install twrp again?
boot into twrp.img then flash the last rom you were using, then flash twrp.zip, reboot into recovery and install magisk 19.4. After reboot you will have to enable all your rooted apps again and install your magisk modules again.

URGENT: disabling magisk made OP6 stuck on bootloader, How to recover from it?

I had latest magisk (stable version) installed and tried to disable it from magisk manager->uninstall->restore images.
when i restarted the phone it stuck on bootloader screen.
I tried to got to twrp recovery mode and it's stuck on the flash screen.
Why would magisk manager put a button which is not working at all and bricks the phone? Please guide me what to do.

Maybe you did something wrong and this isn't Magisk fault ?
Go to twrp and wipe system and vendor DO NOT REBOOT, flash OOS zip and twrp again, and it shall work,
NOTE: you will NOT lose any files or data

Recovery Bootlooop Please Help *Urgent*

I decided to root my Oneplus 6 (10.30.1) yesterday and everything went fine using TWRP 3.3.1.17 mauronofrio and Magisk 20.3.
Today I wanted to installed EdXposed which I did by going in to Magisk Manager, install Riru, reboot, install EdXposed and then reboot.
However, after installing EdXposed my phone would not boot, it would just hang on the loading screen.
I forced a reboot in to TWRP recovery and proceeded to restore my nandroid backup. This only made things worse.
When i try to boot I get the unlocked bootloader warning, it tries to boot in to the OS for about one second, then back to the bootloader warning screen and so on and so on.
I can still boot in to TWRP with Vol down + Power and i've tried wiping data and i've tried 'fix recovery bootloop' in the advanced settings but neither has worked.
Could someone kindly help fix this? I dont mind if i have to reinstall a stock Rom and lose root etc. I just want my phone back
Thanks

Use the msm tool to recover your device...
Try booting into the mauronofrio twrp recovery from fastboot. Then wipe the system partition and reinstall your rom.
Then boot mauronofrio twrp again from fastboot and install the zip, and reboot to recovery.
Install custom kernel, Magisk.
Uninstall edexposed
People reply here with no clue and advise to just restore stock. How is this a solution and how did not OP think of it themselves?
This is too little too late, but maybe it helps someone else:
Unofficial TWRP for Android 10 is glitchy. E.g. nanodroid backups are not restoring properly. Given current A/B mess this is not at all surprising.
Solution: wipe everything, reinstall *same* lineageOS version as before, flash same gapps as you had, and if you took the nanodroid backup after magisk, install it as well.
Don't boot yet!
Restore the backup *partially*, e.g. only the data partition.
This should work.
Or, emh, it did for me with some minor glitches. But even Google Authenticator didn't notice spoofing (otherwise RIP my accounts). So, i definitely recommend trying this workaround.

Bootloop after magisk module install

Hello everyone,
I recently installed Magisk and TWRP and at first everything was working completely fine, than I installed the f-droid privileged extension module the device started bootlooping.
I managed to fix the issue through TWRP (Fix bootloop option) and completely uninstalled Magisk through the official uninstaller. Thing is every time I'm trying to reinstall Magisk the problem returns.
Please help.
Happened to me to....you need to uninstall that exact module from your system....
You can uninstall any modules even from TWRP...
go to file explorer on TWRP
Open data then adb an then modules and delete unnecessary folder otf module...

This is strange normally when you flash magisk uninstaller every module will be uninstalled, it's used to do a clean flash of magisk, infact when you reinstall magisk no module will be there and you need to reinstall everything

Indeed. How should I proceed then? Could the "Fix bootloop option" in TWRP caused the issue?

Let me think
Try this:
1) flash latest magisk uninstaller
2) reboot to system and make sure it's starting and working (no bootloop and/or no other problems)
3) Reboot to TWRP and flash magisk, don't let TWRP doing anything else
4) reboot to system, it must be works
Alternative is:
1) flash latest magisk uninstaller
2) reboot to system and make sure it's starting and working (no bootloop and/or no other problems)
3) reboot to TWRP, dirty flash latest oos (10.3.1), then TWRP, reboot to TWRP
4) same as point 3
5) once you've reboot to TWRP at least one time after flashing oos, flash latest magisk
6) reboot to system
Only question is: which magisk version are you using?
EDIT: If "Fix bootloop option" is a flashable TWRP file, then follow directly the alternative way
I have just tried the first method and unfortunately it did not work. The device keeps booting into fastboot instead of system. I will try the second method tomorrow and report here. Just to make sure I have it right, dirty flash is flashing the ROM without wiping the data first?
Magisk version is latest stable v20.3

Thanks! The second solution did the trick. I'm pretty sure TWRP "Fix bootloop option" somehow caused the issue.

Great! :good:
Because once you flash "Fix bootloop option" it will stay in system partition and the only way to remove is to reflash system through oos zip
hahaha i think magisk rooting method fail from safetynet check and module install. After a bootloader from specific module (disablerliboemencrypto) i restore my stuff to try another module (Bluetooth ..) a bootloop again happen
sorry but,GOOGLE beats YOU @topjohnwu.

Phone stuck at boot after uninstalling Magisk from app

I installed Magisk via twrp(Temp version). and installed a bunch of modules.
Then I decided to complexly uninstall Magisk. I've done that from the Magisk Manager apk(The Complete Uninstall button)..
The phone rebooted and stuck into the phone logo with red danger logo. which means perhaps the boot img is missing ?
I should have uninstalled the modules first, which might have caused this issue..
Now, I Flashed Magisk again via Temp twrp, but now few apps keeps crashing, even after uninstalling and installing them.
i don't have the stock bot image, otherwise i guess i can do fastboot boot boot.img to escape the boot issue after uninstalling Magisk from the app
Note : i tried flashing the uninstall zip file from twrp but that didn't work, Magisk framework still exists !
What should i do now ?
My HTC is the duel sim version (Asia) and i'm using Magisk 22 latest version
Have you tried cleaning dalvik cache?

I did, No luck. The reason I'm trying to unRoot my device is because a mobile banking app is detecting Magisk. the app keeps crashing after i add it to the Magisk hide menu

If it is just the banking app then you can get "MagiskHide" and "Safety Net Fix" modules from magisk.
If your phone stuck in bootloop or other apps are still crashing then you have to wipe dalvik cache again.
If you still need to unroot for whatever reason then try this:
Try updating magisk first then clicking uninstall from magisk manager
Try manually flashing uninstaller.zip from TWRP
Try flashing the uninstaller as a module as stated in this post
Finally if it's still no use, then you can factory reset the device and it will remove the root

I'm on the last version of Magisk. I tried to uninstall it from the app but it stuck at the boot logo with danger logo.
I also tired to flash multiple zip files but still Magisk exists after reboot.
That leaves me with last option. Factory reset. s it safe to do it even with magisk installed ? because the boot img is patched and when i try yo restore the original boot img, it just don't exist in Magisk !

No if it is a patched boot image then you'll have to flash the stock one.
Factory resetting a patched image puts the device in a bootloop.

Yes. This is what i was afraid of. I don't have the stock boot img. if you can help me with that, it will be great, my phone firmware (htc/imedugl_00401/htc_imgedugl 9/PQ2A. 190205.003/1088647.3)

You can find your device's ROM here (Literally first google results..):
HTC website
HTC dev center
GetDriodTips (Only for U12+)
**Disclaimer:** I don't own any of those ROMs and I don't hold responsibility whatsoever should you brick your phone or anything goes awry.
had exactly the same issue and exactly due to the same reason (I hate those pseudo-secure banking apps).
I couldn't wipe dalvik as TWRP is still not available for my P5.
But it was fixable really easy by reflashing the patched boot.img:
run command "fastboot flash boot magisk_patched.img"
btw I'm still looking for a solution for that stupid banking app.
I tried the above mentioned "magisk hide" and "safety net fix" and tried hiding the app itself but all that does not help.
Can we delete magisk and still use the phone rooted ? Or will it unroot my phone if magisk is removed. I’m planning to sell my s10 and the buyer does not want the application.
Good information from GetDriodTips (Only for U12+). Thank you.
