Well my issue here is that I can't find any intel about the major diffrences between the devices. And mostly why Google play aint working and such.
Just another question tho: Was Google Play preinstalled?

If I look through many websites and intel from Sony itself the m35h is in the same line as the C530x line. And will nearly be the same as the C5302.. However I am not sure.
This means that the m35h is not for chinese market.
I came across many sites that tells that the m35t is for the chinese market..
You could try to check if there is an LTE mode on your device and even try to flash a C5302 fw file but that could also be risky.
So what I can tell short:
C5302 and M35h are most likely the same only other codename and perhaps some more things. (not sure)
