Why decription failed on oreo 8.1 after update (keys not properly upgraded?)?

After updating, device can't decrypt user data. Seems like some keys not updated properly. Flashing back older firmware doesn't helps cause of google new anti-roollback feature. How to fix that and decrypt my data? I'm ulocked.
