Xtrons tda696a

Hi all,
Ive got an xtrons tda696 with android 4.4.4_22072015
I have root access but wanted to check if there is any firmware or roms I can use.
chip is the rk3188 and mcu is MTCB-HZC-V2.69
Ive looked at all the roms and firmware here but the mcu doesn't appear to be listed.

Any help or suggestions please:D
