Re: WARNING: Never Change Radio Band

, i make same mistake, with a zte nubia, and solved with a program from zte, and i was luck y that i bought the same phone with another friend. So with this program saved the params from his phone and put it to mine. The file is nv.qcn That i think is find in the qualcomm ( xiaomi mi 5 ) so if you find a similar phone, and you can copy the nv.qcn, and put it on your phone... that i think will solve the problem. You can edit the nv.qcn... but i think will be more difficult. When you replace nv.qcn from another phone don t wory... willl not copy the imei, your imei is write protected file so is imposible to rewrite , it will copy only the parameters and unlok the bands...is a delicate issue. I saw on a forum, that if you delete memtest1 and memtest2, it will work... i don t test this. If you want to test this way, strongly recomand to do a efs back up, worst case , you will came back at the start point ( USA BAND)

Re: WARNING: Never Change Radio Band

Hello,

 

i am facing similar problem, i have a moto x style pure edition.

I changed the Select band option to 'Cellular band' and then to 
"US Band". I lost netwrok signal after that. Please help me.

Will factory reset work?

OR do i need to flash the phone.
