Mi Max(hydrogen) bootloop after TWRP flashing

Hi there.
I'm using Global Developer ROM(MIUI9, 8.4.19).
And I'm trying to flash TWRP and install Custom ROM.
I asked Xiaomi for unlock my bootloader, and after 72 hours I could unlock my phone.
After that, I flashed TWRP 3.2.1-4.
Method to flash :
1. Boot into fastboot mode(vol down + power)
2. On windows command prompt, type "fastboot flash recovery twrp.img", "fastboot reboot"
but I can't boot normally, only can boot fastboot & TWRP recovery.
I tried several methods.
1. Try LazyFlasher - bootloop, nothing was changed.
2. Try to flash another ROM(8.1 OmniROM) and gapps(OpenGapps, ARM64 pico) - same bootloop, with Omni bootlogo.
3. Try to flash OmniROM and LazyFlasher - same bootloop.
I can revoke my phone by Fastboot ROM and have no problem without trivial permission reset, but I can't use TWRP still.
Any methods to flash TWRP without bootloop?

flashing twrp doesnt cause bootloop. you went wrong somewhere. did you format system partition before flashing new rom?

Of course.
On the other hand, definitely, just flashing TWRP causes bootloop. I assume that stock beta rom might cause bootloop by incompatibility of TWRP, but I can't return to stock stable rom because I can't use TWRP recovery so I would lose all of my data.

try using stable rom. when i bought this phone2 years ago, i could flash twrp and root miui just fine

Stuck in fastboot after MIUI 11

After flashing MIUI 11 beta I decided to go back to crDroid. Restored backup via twrp but it wouldn't boot, just booted into recovery, but twrp wouldn't decrypt data. I've seen this before and solved it by adb sideload crdroid rom (maybe because it includes vendor?). I tried this and now it just boots straight into fastboot. I tried fastboot boot twrp.img and that says "failed to load/authenticate boot image". What should I do?
Edit: After using miflash I can get back to stock, and then use fastboot to flash twrp. Twrp still doesn't ask for password to decrypt data. Every time I try to adb sideload crdroid.zip i end up stuck with fastboot again and have to miflash!?

Full wipe in TWRP and format data partition
reboot in recovery
flash crdroid and flash magisk

flash vmbeta after rom

I tried full wipes including data and flashing crdroid. I've also tried flashing vbmeta at multiple points.
Even after flashing back to stock miui with miflash android wouldn't boot, instead it just loaded miassistant (miui recovery). I'd have to flash twrp again, try flashing a new system and it would always reboot to fastboot.
The only solution has been to flash back to miui 11 beta (android 10) which boots fine. I'm still not sure whats going on but I'm ok with miui for now.

Bootloop after flashing GSI

I was flashing PHH's AOSP GSI ROM (version 208, AB, GAPPS included) to my RN8P. This is a supported ROM and should theoretically work. I did this without TWRP and wiped data using ADB. It is important to note that at this point I decided that it probably should have TWRP anyway and flashed that before flashing my ROM using
Code:
fastboot flash system (name of rom).img
I then rebooted to find my phone in a bootloop. I am letting the power drain at the moment but I have no idea what to do when I power it on again.

Guide to flash custom roms

Hi there and I want few information about how to flash custom ROMs on my rn5 I have unlock bootloader and install Fox TWRP and I have tried flashing c a c Droid and Google pixel the process has gone correctly but I am unable to boot in those ROMs I have cleared wipe cache, system vendor custom,
I did all I can do but I am unable to boot in custom ROMs after flashing so if anybody have any steps kindly guide me thank you

I always have difficulty to flash ROMs on the RN5 Pro, always after startup it returns to recovery without the ROM I just flashed. My solution was to put the files (OrangeFox and Custon Rom) on the SD card before cleaning and then use the command "fastboot boot TWRPName.img" to clean the entire system and then install the recovery and ROM

OP7T ROM Installing Partition Error

After trying to install a custom ROM (PixelExperience for OnePlus 7T [hotdogb]) via fastboot, the installation flashing ended with errors with "no such partition" for odm, product and system I tried everything to get out of the fastboot screen loop. After finding a bat file with IMG files which got me on the Android 11 Beta 1. build (still no WiFi)
What can I do to fix the partition error to get on the Pixel Experience ROM or even get back to the stable build - I did try MSM but it isn't listing the phone even after pressing ENUM.
Please help...
Context (can skip): The latest stable build OOS for my 7T had issues with the microphone not working and so I decided to do a factory reset which resulted in having a clean install but now, WiFi doesn't connect for some reason. After trying some fixes I decided to install a custom ROM.

U need to flash stock recovery (fastboot flash recovery recovery.img) as twrp prevents fastbootD entry. Then type fastboot reboot fastboot to enter fastbootD. Then flash your rom. Personally, I just flash roms via Chinese twrp or 3.5.10 twrp

that was my process for the first try - entered fastbootD for the flashing process which ended with the mentioned partition error and the fastboot loop. I realised that TWRP version I got from TOOL ALL IN ONE wasn't going to work as it couldn't access data no matter what.

No twrp can decrypt oos or a11 custom roms data. Chinese twrp can access data only on a10 custom roms if u remove screen lock before booting into twrp for backup

What do you reckon I try this time then?
