Boot Loop

So, I was on Android 10, I was trying to root using Magisk & TWRP as mentioned in this XDA Post.
Title:: "[RECOVERY] TWRP 3.3.0 for Galaxy M20" , By DarkLord1731, Senior Member on 3rd March 2019, 08:54 AM (**mentioning because i cant post link**)

Even after multiple attempts, I was unable to install
1. no-verity-opt-encrypt 2. RMM Bypass zip using TWRP.
Both kept on failing even when i tried different versions.
-------------
Later on when i tried flashing SuperSU , phone got bootlocked :( :( :(
still stuck, any help would be appreciated.

-------
Installation Steps:
- First, make sure your phone isn't RMM Locked.
- Download Odin3 v3.13.1, Samsung USB Drivers, latest TWRP's tar for your variant, latest no-verity-opt-encrypt zip, latest Magisk.zip and RMM Bypass zip by Black Mesa, and copy all of them to your external sd card.
- Go to Settings App, Developer Options and enable OEM Unlock (If you don't see Developer Setings, go into About phone>Software info and tap "Build number" 10 times to show Developer Options menu).
- Do a backup of all your important data and files in your phone.
- Shutdown the phone. Once it's off, Power it On in Download Mode (Connect your phone to your PC, press and hold Power, Vol + and Vol - buttons together )
- Open Odin3, go in Option section and untick "Auto-reboot". Once that click the "AP" button and select the TWRP tar you downloaded before, then press the "Start" button.
- Once Odin3 finished to flash the recovery (you should see a "PASS" message), force reboot your phone (Press and hold Power and Vol - buttons together) and once the screen is off, press and hold Power and Vol + buttons together to boot in TWRP.
- Once TWRP is booted you first need to decrypt your /data partition. To do so touch Wipe>Format Data and follow the instructions in screen.
- Once it finished go back at the home screen and touch Reboot>Recovery. TWRP should be able to mount your data partition. Now flash the no-verity-opt-encrypt, Magisk(necessary to prevent bootloops) and RMM Bypass zip you downloaded before (touch Install and select each zip to flash it)
- You're now able to reboot to your OS without re-encrypting /data partition and without RMM Prenormal lock.

Hello Sir. I'm trying to install Project Sakura on my M20. In which order should i flash the zip file of the rom? Sorry, newbie here.

- Once it finished go back at the home screen and touch Reboot>Recovery. TWRP should be able to mount your data partition. Now flash the no-verity-opt-encrypt, Magisk(necessary to prevent bootloops) and RMM Bypass zip you downloaded before (touch Install and select each zip to flash it)
- You're now able to reboot to your OS without re-encrypting /data partition and without RMM Prenormal lock.
