Baseband Problems

[919array]

Hi, I live in Spain and I have problems with my phone bands, indoors I can not talk to the phone, and I have not 4G only H or H+, coverage while my Huawei P8 and another phones, yes.

Solution? enter engineer mode *#*#3646633#*#* and "Bandmode" to change the bands most suitable for my country and everything is perfect ...

But the problem is when restart, can not detect the sim card and I have to restore whith the TWRP the nvdata and nvram and returns to the original state bands.

Does anyone have this same problem?

Does anyone know any solution to this problem?

Is there any way to flash any baseband suited to European operators?

1. Fix BaseBand first at http://en.miui.com/thread-429027-1-1.html
2. Fix IMEI at http://en.miui.com/thread-428917-1-1.html

Read the instructions carefully and ensure that all MTK driver installed properly.
