PAra cambair los IMEIS, probado que funciona en otros moviles con MT6589:
1. Engineering menu - code *#*#3646633#*#*
2. Enter: "CDS Information"/"Radio Information"/"Phone1" (or "Phone2" respectively for sim1 or sim2).
3 for sim1. In the box that says "AT+" appends "EGMR=1,7,"my_imei1"".
It should look: "AT+EGMR=1,7,"my_imei1"". Press "SEND AT COMMAND".
3 for sim2. In the box that says "AT+" appends "EGMR=1,10,"my_imei2"".
It should look: "AT+EGMR=1,10,"my_imei2"". Press "SEND AT COMMAND".
