1.By above I guess my phone is of AO type firmware(not AS).
so what is the latest firmware update available for an unbranded phone?

2.
C902_R3EA038_MAIN_GENERIC_AS_RED52 this is the latest firmware available in this
sites down load.(Top Sony Forums)

Is this for AO firmware or AS firm ware?

R3DA032_RED52 ( C902_R3DA032_MAIN_CHINA_AO_RED52) is another firmware
can I choose this one to flash??( english is my main language)
