Is it possible to back up phone SN number? Does it copy with imei or is it included in an OEMINFO file? After uploading certificates from another phone to change only imei

You can Read (Backup original IMEI(s) and network lock state) and Write Huawei certificate (secure data) with Sigma. GSM Network will receive the desired IMEI number.
Sigma will read actual IMEI from OEM info area and show it in the log.

Did I understand your question correctly?

What serial number you are talking about? "Battery serial number"?
Sigma works with battery SN and cert file (IMEI).

We do not work with other serial numbers. Please show a practical situation of using the function you need.
