  • Hello Abhijeet Bharekar,

    thank you for the HowTo for installing the cwm on Galaxy Core 2.

    But there is a question. The picture with the explanation which keys must be pressed to enter the recovery mode shows a Galaxy Core 2 Duos.
    The text is written for SM-G355H (single SIM-Card)

    So i’m a little bit unsure if this mod works on a Core 2 Duos too and supports both SIM-Cards.
    Can you give me an information to this issue?

    Best regards
    Thomas
