I have flashed the new update(4.4.2) for the S4-Mini black via Odin on my S4-Mini (normal). Now I do not like this FW and I want to downgrade back to the old one (4.2.2). ( I have of course tried to just flashed the FW, like I updated my Phone, but Odin just gives me a Fail(AUTH).)Is there a file that i am missing? If yes, where do i find this file? Or do you have to use a different method?
