I bought one iphone 4s android 2.3.4, MTK6573, 1 micro sim, 3G, retina (640x960). But, I do not know what it is CIPHONE or Sophone or Hiphone etc. Just know that SW 0502C040-168SM10CA-Jiayi-C223-IND SN: MA68SHX23801742 Due to the wrong upgrade, now can not boot. I've been trying to find a suitable firmware, but can not. Hope you can help me find it. Thank a lot.
