DIFF FIRMWARE BASE
Flash rom thru recovery without wiping anything
Turn off device. (Hold power button + vol up until vibrates 3 times) [or use recovery turn off device option, if any]
Flash latest Sony's firmware (FTF) matching current latest monIFIED base rom using flashtools. Uncheck all WIPE options and exclude all EXCEPT KERNEL & BASEBAND to get latest matched kernel & baseband.
