Recovery bootloop - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hi,
i have an issue with my phone constantly rebooting to the recovery.
I have TWRP installed and tried various things (factory reset, full wipe) with restoring partial previous backup or re-installing lineage 17 but could't fix the issue.
At best it passes MI logo and load lineage boot animation then suddenly reboot to TWRP or sometimes doesn't even load the lineage animation (twice MI logo then TWRP).
I need help identifying and fixing the issue please.
Thanks

Go to fastboot, flash twrp with adb, boot to twrp and format data, reboot twrp, factory reset, flash only Lineage.
Or flash stock MIUI, and from MIUI go all yhe way back to Lineage

Bricked! Stuck at MI Logo

My phone does not boot past the Mi logo and shuts off a few seconds after showing the Mi logo. I tried booting to TWRP but the same thing happens - phone shuts off after Mi logo. Phone is able to go into fast boot mode.
I have an unlocked bootloader and was running the Oreo RR. To update to the treble ROM, I flashed the TeamReloaded TWRP and that went smooth. I rebooted to system and there were no issues. After this I wiped dalvik and cache and flashed the Treble Oreo RR ROM and Magisk 16.4 . After this I tried rebooting and ran into this problem. Also, I have an encrypted storage.
Buddy reinstall twrp and Rom. That's the solution I found. Don't install magisk. It happened to me too
1.Flash Treble supported recovery in Fastboot mode
2.Boot into recovery
3.Decrypt your phone (factory reset)
4.Enable Treble support in recovery
5.Now flash any ROM you want.
flash stock boot.img first then flash your rom if uh want to flash treble rom then flash treble supported recovery n enable treble support in recovery if uh want to flash non-treble rom then flash non-treble recovery then flash stock boot.img then flash your rom

I´m on bootloop on TWRP.

I have the same issue. https://forum.xda-developers.com/g5-plus/help/twrp-bootloop-t3740873
Im using latest twrp, im flashing Syberia Project + Magisk + Gapps
Then I reboot and it boots on TWRP, if I factory reset from the options on fastboot, it will start but without gapps and magisk, and if i try to install again those two, same thing happen, twrp bootloop
I saw some people that can start the phone on the OS using the start option from fastboot mode, but when i do this, it will start to boot on the rom for like 3 seconds, then it will turn the screen off, than twrp appears, please help.

Help booting into recovery(bootanimation loop)

I flashed a mod for Nougat(I'm on crDroid 7.1.2) on my D801, am no longer able to boot, the bootanimation just loops.
Is there any way to boot into recovery and dirty flash? I'm only able to get to the factory reset screen, and I'd rather not factory reset/wipe data

[solved] stuck on bootloop after flashing los 17

steps i did:
installed twrp twrp-3.4.0-1-markw
flashed lineage-17.1-20200920-UNOFFICIAL-markw by shiabzzz
wiped data and cache, excluding internal storage
tried to flash gaps but failed due to error 20
flashed magisk
reboot.
now im stuck on bootloop. i know i should have deleted data before flashing the rom, not afterwards. when i press power+up it's not going to recovery.
how can i fix it?
are gaps mandatory for it to boot?
will my phone turn off when it runs out of battery, will i be able to go to recovery then?
update: i can access fastboot mode, but when connecting to pc and trying to boot to recovery it says "waiting for device".

Problem with recovery and bootloader

I was using OrangeFox and tried to flash PixelExperience 11 from PixelExperience 10.
The flash went smoothly, but it goes to bootloop after i restart.
So i go back to OrangeFox to format my data and tried to reboot once again to finally get it working.
Then i tried to install magisk but my my recovery has encryption problem.
So i tried to install OrangeFox from ADB sideload but got error message halfway.
Now whenever i tried to reboot into recovery, it just go through the system and reboot just fine.
And to make it worse. Everytime i go to bootloader i just get blank screen and fastboot can't detect it.
My problem is PE 11 is so unstable and some of my apps won't even open.
Now is there any way to fix my recovery or bootloader?
