Redmi 3s Lock To Usa Band, Help Required

[fmkhan100]

Hello members, I bought redmi 3s one day ago. By mistake it is locked to USA band. Now my sim 1 is not working, the phone detects the sim but there are no signals, I can't use sim 1 for anything. Kindly help me to fix this.

I google and found 1 possible way to fix this is to restore QCN file,,, can somebody please give me qcn file for redmi 3s?
Thanks

I have the same problem. There is no decision yet. Support of the producer still distinctly has not answered.

Hello everyone,

I have made a mistake with usa band and looked how to fix it. And i have found a soluce

For information i have a redmi 3x locked in France

I just downloaded this rom
land_global_images_V8.0.3.0.MALMIDG_20160805.0000.29_6.0_global_588e5c60af

and flashed with xiaomiflashtool

i asked for unlock, and i flashed twrp recovery with new rom and rooted the phone.

With new rom and rooted phone, always band problem, but with wifi i justupdated all apps, and superuser and i downloaded the apk network signal guru.

He detects the band where you are you have just to lock what you need and now my phone is back to life.
