First of all, I am rooted and S-On. Although, with my problem, I am essentially unrooted as superSU will not flash via TWRP. I get 'Unable to open zip file'. It isn't a problem with the zip as the MD5 is okay. When I try to open the superSU app, I get 'The SU binary needs to be updated' and it pretty much renders it useless as no apps can get root access until I update.
I am new to HTC devices but from what I understand, S-On shouldn't affect this right? I'm just not sure what could be causing it. Thanks
