[Q] HTC One flashing topic

on 9 Jan I posted: I have rooted my One S ville, installed SuperSU and TWRP. i am now trying to flash CM10.2.0 ville, but getting errors. I wiped my storage, but when I run the flash process it tells me "failed to get default contexts and file mode for storage files" ( looks to me like a permissions problem). Then at the end it tells me it had an error executing update binary, etc etc.

So what is the fix?

hboot 2.15
currently running 4.1.1. through T-Mobile.

Part 2: on 11 Jan update: I think I put myself in a hole.. I read about the issues with s-off on HTC devices. So I did the steps to make my recovery ROM (TWRP) my boot ROM. I still could not flash CM10 or CM12 or superuser, for the same errors as above. NOW when I boot into any mode, it always goes to TWRP.
