Question Update to OOS 13 with Magisk and TWRP

[WSZR]

Hi. I would like to install OOS 13 with Magisk and TWRP. When I bought the phone I had OOS 12.1. I unlocked the bootloader, I wanted to load TWRP for this Android version (https://forum.xda-developers.com/t/...twrp-with-a12-a13-encryption-support.4523857/) using vendor_boot.img and boot.img, but my smartphone bricked. I saved it with MSM. Current OOS version 11.4.4. What are the best steps to take now to safely do TWRP and Magisk and update to OOS 13?

You can"t flash from OOS 11 to OOS 13, tyou have to go thru intermediary OTA updates.
Why would you like to use TWRP to flash OOS OTAs ?
Update normally as per your system OTAs

I know I can't from OOS 11 to OOS 13. I just want to set up the steps so that I have TWRP. I want to be able to make a full backup. For OOS 12.1 and 13 TWRP is unofficial. Maybe there is another recovery yet.
