Reboot into Bootloop after flashing ROM - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hello guys,
I have a problem. Everytime I flash a custom ROM (not based on MIUI, so not Xiaomi.eu etc.), install Magisk + mandatory add-on in Magisk Manager (and successfully reboot into system), and then restore all my apps, and then REBOOT, I'm stuck in fastboot. I have to flash MIUI via FlashTool and reflash everything to back to Custom ROM. I haven't found the issue yet (what causes it to reboot in fastboot everytime).
Do you guys have an idea or experienced a similar issue?

K20 Pro China ROM Magisk Bootloop Problem

Read a similar problem from this thread https://forum.xda-developers.com/k20-pro/how-to/redmi-k20-pro-firmware-10-3-8-0-9-6-13-t3939647
I'm already unlocked and I was gonna stick with the China ROM for now, so I flashed Magisk. After an hour I noticed my root access WAS GONE. So tried restarting it and... bootloop! Magisk uninstaller fixed this BUT I want that Magisk. So I kept retrying... Fastboot, flash TWRP(another issue is TWRP wont stick no matter what it will be replaced by stock recovery), Install magisk, bootloop... Rinse and repeat.
I tried 2 methods installing Magisk. TWRP and the Boot Image Patching using boot.img from latest China ROM miui_RAPHAEL_V10.3.12.0.PFKCNXM_75ea367433_9.0.zip
Im running out of ideas, can anyone here help and share how they fixed it? Thanks!
you should change to Xiaomi EU rom, no issues with Magisk.
Try installing ver 18 or 18.1 magisk i had issues with ver 19 and up on pocof1. Also on pocof1 you had to install dfe (disable force encryption) and them twrp wouldnt be replaced with stock boot recovery. Also any update that comes when twrp is installed will rewrite it to stock recovery.
Wipe userdata/factory reset after installing magisk
I have the same issue and resolve it by install OrangeFox-R10.0_8-Stable & Magisk-v20.1.zip.

Phone keep rebooting into recovery mode only

Guys! I need help!
My Mi8 keep booting into recovery. I tried:
- Clean flash p4r
- Clean flash MIUI stock with miFlash
- Flash Miui EU, Miui Mix
- Change another recovery
But the phone keep booting into recovery even when flash succeeded. Can somebody help me with this?
Update 1: After mounted my system and flash some rom, it booted but after reboot once. The problem happened again
First I would stay away from blind builds such as miui mix.
Your issue is probably corruption or encryption.

Help needed! Rebooting to fastboot

Hello friends,
I am not new with locking/unlocking, flashing roms....
I used to install different roms and had different problems but never met something like this.
so the problem is:
I unlocked my phone, installed twrp and tried to flash different roms (OOS, Lineage, Pixel experience) but it is still rebooting to fastboot and Im not able to go back to twrp recovery unless I flash bacl stock rom via miflash and flash twrp again.
I tried different twrps as well, wiped data, factory reset, advanced wipe.. still not able to flash any rom.

When flashing over stock MIUI you need to format data in TWRP. (Format, not wipe, need to type 'yes' to confirm.
Also, when restoring MIUI, make sure you boot into MIUI once before you flash anything else.
Use the latest 3.3.1-32 TWRP from here
https://forum.xda-developers.com/k2...icial-twrp-xiaomi-redmi-t3944363/post79823568
Restore MIUI and boot into it.
Flash TWRP and boot into TWRP
Do a factory reset.
Format data.
Reboot into TWRP - this ensures the formatted data partition is mounted properly.
Flash the ROM, plus any extras.
Boot into system.
Everything should be good.
Maybe its problem with vbmeta, try to flash vbmeta first, but you need to boot to twrp trough adb command, then flash vbmeta, than flash twrp, reboot to twrp and flash vendor, rom if you want to ide custom rom, not Stock

There shouldn't be any need to flash vbmeta.
In theory vbmeta would only be needed if you want to stick with MIUI, but without root, but want to install TWRP, maybe to debloat.
Flashing Magisk or flashing a custom ROM should remove the need to flash vbmeta.
If you're already on the latest MIUI there is no need to flash any vendor files, as they're already installed.
I dont know why, but Yesterday ive tried to flash custom rom, wiped everything and after flash and reboot the phone stucked in fastboot, wont boot to twrp,not with butt shortcut,not with adb command. So i try to flash vbmeta,than IT boots to twrp,and Also i was able to flash again twrp, this could be Also solution.

Losing Recovery after install Custom ROM

Hi,
I have the following problem.
I was able to install the custom ROM properly on my Mi9t pro. Unfortunately my Orangefox Recovery was deleted After the installation.
If I want to install Magisk now, I have to reflash the recovery first.
Do you have any idea why the recovery is deleted? Is there a way to prevent that?
Thanks in advance.

Your (custom) Recovery was really deleted?
Or replaced by stock Recovery
Who says that installation of Magisk requires custom Recovery?
Magisk documentation (Installation Instructions) - please find it on Magisk Github - certainly not.
Patch the boot.img and flash (it can be flashed by Fastboot, hence custom Recovery is not a must to have)
Hi,
it really gets deleted. My cell phone is then only in fastboot mode.
I am not interested in flashing Magisk either, but rather that recovery after an installation is no longer available. This makes installing updates more cumbersome.
I only have the problem when I flash a custom ROM. when I flash a MIUI ROM from xiaomi.eu Beta, the recovery is retained.

Poco x3 nfc not booting after flashing magisk

Yesterday i flashed magisk (using the new method of course) and when i tried to boot it would stop on the miui boot screen. I can go into fastboot and recovery but i dont have twrp installed.
If anybody could help i would be grateful.
Update: The phone now says system is destroyed when i try to boot into recovery, should i just fresh install miui?
Also there is a roll back function that triggers when you install unverified img files so i think the cause is that.
Fresh install worked.
now my device works
