Ok, well, I didn't manage to install this ROM. I used previous LegionOS with MIUI vendor, also several of OSS roms. I tried to flash the newest build but it boot into recovery. So i used DmVerity/ForceEncrypt zip after rom flash and I managed to see Legion logo but with bootloop. Tried both GAPPS and Vanilla.
Flashing another OSS rom like Corvus work great. Am I doing something wrong?

Something with encryption maybe? I wiped system/data/vendor/cache partition, should I format /data then?

EDIT: Solved. Full data format did a job.
