So i have a Samsung Galaxy S6 SM-G920R4 (US Cellular) and tried flash TWRP to it which worked but switched the left and right touch so if you touch on the right side it responds on the left and vise versa. So went into TWRP and erased eveything (Operating system , revovery, everything) But now whenever i try to flash the original firmware using odin it always fails. Yes I am using the correct firmware. Any help on this?
