I have se xperia acro is11s device by AU KDDI.
I unlock it from operator by x10unlock tool.
My operator (NTC Russia) work on it, but i have no any GPRS functions an cannot send SMS, because AU is CDMA operator. I must flash firmware for it become LT15 or SO-02c (NTT Docomo).
When i flash LT15i_4.0.1.A.0.283_Generic Global.ftf, after flash complete power on phone hang logo SE.

I unpacked the original firmware and replace system.sin from LT15i. then made bundle creation in FlashTool, then i flash phone.
