Hi guys, maybe someone can help me. I have unlocked boot loader on xperia m, then locked it back and the bad thing is I didn't do back up of drm keys. so now when i do screen mirroring I get dhcp error. Is it possible to disable dhcp check or get drm keys somewhere? installing custom firmware is not an option, because I was late to work once because alarm failed on custom firmware and had other few bugs. is there any solution to make screen mirroring workk again? now I'm running 4.3 rooted. thanks guys
