Hello
I Have 2 Models Of Module Sim900A.
First Module (S2-1040V-Z0958) is 64 MB Flash Version And Default Firmware Is :1137B12SIM900A64_ST
Second Module (S2-1040V-Z095R) is 64 MB Flash Version And Default Firmware Is :1137B02SIM900A64_ST_ENHANCE
since ENHANCE Firmware Support All Function (Decode DTMF , Jamming , ...) How I Can Read Firmware From Second Module And Write into First Module?

Best Regards
