Nobody has not solved the ROM problem of Casio commando C811 (m070) ussd cod request or Chinese respond code . I visited different forums for finding a solution that a lot of other owner of other brands of cellphones have been faced with such problem also. I have not found any thing so far.
I tried different methods the only way that worked was using old rom or downgrading to m020 rom that has a lot of weak points.
low GSM signal connection
GPS problem
quick setting stop to work
and so on
