Hi! I need your help! My iphone android 2,3,4 retina, 1 micro sim, 3G

[tuanhuudl]

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.
