Hi there, I wiped also via TWRP and still same error message but maybe this is more an issue related to CM 12.1. Maybe I'll post in the official CM 12.1 thread for Xperia T
and post back here when I've found the proper solution (for completeness).
Actually I googled and some people suggest to update TWRP, but since I have the last version (for my device, which is "mint") I guess I can only ask the TWRP maintainer of "mint" on xda
if he knows something about this issue.
I'll keep you updated
thx so far. cheers
