Poor Reception. Help!

Feb 10, 2016
I have white redmi note 2 32gb in white. There is Chinamobile 4G LTE branding on back cover. Phone is rooted and unofficial eu rom installed ver LHMCNDB stable.

I am aware of Band 20 missing but same mobile in black version with Chinamobile branding is all good with no such problems. Does this China version redmi note 2 have own custom rom different to non China version?

I have attached phone info pic & bug report. Can anyone help me before I open ticket on GB & Paypal
