Please help! I am trying to flash the latest global stable or developer ROM to Mi4 with MIUI Global 220.127.116.11 (KXGCNCK) that I suspect is a modified ROM because of al the popup comercials and such. I tried using Mi Flash, downloaded the latest Global ROM (tried both Global and Developer). When I press Flash I get to 1s and it says succesful. Bootloader is locked, I don't know if that's the problem. It was bought that way.
