Did you tried to find and use any other similar firmware for this type of phones ?

Just an idea: phone firmware that you talk about has a bug and as a result phone eeprom become damaged after some time.

[KUBAT1]

[InfinityHelp]

hello guys!

nearest Cinese Miracle update will support this option (default IMEI number editing)
this will solve automaticly resetted IMEI probelm

[InfinitySupport]

Hello,

If problem still exist there is a way: use ChineseMiracle v2.70 and repair "imei inside firmware".
After this operation even if imei will be resetted automatically it will be resetted to value that you already programmed.

[raza786]

Thank you very much
Keep up the good support
