I have a A70. It was unlocked but it hadn't got my language that's why i downloaded software from siemens offical web page. I couldnt see the variant. After the software upgrade, it cant find network. I see the E109(on little white paper) numbers under the battery. I think it is the variant. If i see the software version and variant, it shows s313.I tried to flash with joker and lot of software upgrade but this variant no changing. How can i repair my phone to find network? Please help!
