[Question] DOOGEE DG300 GSM/WCDMA network problem

[Aksom16]

Hello friends,

I bought a DOOGEE DG 300 recently, after manipulating ROM suff files, the network of the phone is gone. I cant get any GSM network unless a port is near. Ive get some "bars" of network by configuring the preferred networks found in the networks settings. ive contacted a TECH support but was unable to fix it (May be due to lack of experience)

Can you guys help me on that issue.. i know some of you may have faced the same problem as me.. please help.

Thanks in advance.
