Phone Miracast Connection trouble (Screen Mirror)


I used to connect my Xperia M to a Sony KDL 60R557A TV using mirror screen without problems.

I made an update when i read a meesage in my phone (new Firmware, new Android Version i guess).

SInce that moment connection doesn't work, there is a message in my tv when i try to connect: "Registration Failed"

Only new is the firmware update in my phone.... No updates in my TV.

Please help me for any solution or if is possible to back my phone to the previous firmware.

My Phone:
Sony Xperia M c1904
Android Version 4.3
Core Version 3.4.0
Compilation Number 15.4.A.0.23

Thanks in advance for your help and time!!!

You can downgrade to previous firmware by flashing ftf file using flashtool. But it not correct solution to resolve screen mirror [emoji15]
