Decided to try myself some RR on the Poco X3 after using it for a while in my Redmi Note 8.
Coming from Xiaomi.eu v12.0.9.0 and after upgrading to the latest TWRP ('twrp-3.5.2_10-5-surya.img', as I was still on brigudav's v3.5.2_10-3) I downloaded everything to an external SD card and prepared to flash by taking a backup with Migrate-NG.
As I decided to downgrade the firmware (to 'fw_surya_miui_SURYAGlobal_V12.0.7.0.QJGMIXM...'), that's the first thing I flashed after which I rebooted into recovery just for safety.
Then I flashed the ROM ('RROS-Q-8.6.9-20210609-surya-Official.zip') and the DFE ('Disable_Dm-Verity_ForceEncrypt_11.02.2020.zip') before formatting data (by confirming with "yes") and rebooting yet again to recovery.
Lastly, I flashed GApps ('open_gapps-arm64-10.0-pico-20210701.zip') because I need to pass SafetyNet (it did) and have access to the Play store.
After rebooting to system, everything looked nominal, with no bootloops or errors.
I rebooted to recovery once more to install Magisk (from TWRP's Advanced options) and flash my Migrate backup -- everything went overly smooth.
Now I'm going through testing connectivity, loging on to G services and tweaking a gazillion options, but up to this point everything appears to be working...
