but I don't see the new imei # . like nothing changes imei # just as /01
Please help. I did all the the trouble shoots but its not working. I did the factory reset and reflash and then re-root it. it keeps saying sucessful but it's not doing it jobs properly. Thanks. It seems like hard to write the new imei on note 4 when its up date to new version 5.1.1. here is the logs :
