Newbie in Samsung cellphone software coding
I'am newbie in Samsung software coding,
Can anyone explain what are exactly: cert, qcn, nv data, patch certificate, refs that are exist in z3x box .
In case we lost signal on someones Samsung phone and IMEI is null what first step we should do: patch cert , write cert or EFS or QCN or NV data ?
Then, in case we lost signal and IMEI is still available, what we should do ?
Is this a good question?
