Please someone can tell me where to download this ROM...
I attach the specification...
That, my friend, is the Original Sophone i6S+, v77_55hd. Should have 1gb of Ram, a four-core 1.3GHz MK6582, and Jellybean 4.2.2
Oh, and the ROM is up on NeedRom, S7yler posted it, look for v77_55hd and you'll find it.
Ah - Different chip though, mine has an MTK6582, sorry. But you have almost identical firmware... :/
