The title is wrong there's no such thing as SODP 12.1.

"can't booting" doesn't mean anything either.

Black Screen or can You just not boot? Does Your Device turn off after saying it is corrupt?
Why are You doing Fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img on AOSP/SODP? That only makes Sense if Your ROM can't pass safety checks which shouldnt be the case... Try flashing without --disable-verity --disable-verification or even without vbmeta
