Locking custom LTE bands on ZTE MF286

My ZTE MF286 is running DNA firmware version B04. It's somewhat limited in LTE band selection, but that can easily be worked around with curl.

First of all authenticate to device using web browser. Otherwise these commands will return failure. You want to see {"result":"success"} message.

# 2100MHz (B1) / 1800MHz (B3) / 2600MHz (B7) / 800MHz (B20) / 700MHz (B28) - this is default setting

Tambahan Band di luar 4G:

0X0800000 WCDMA BAND2
0X4000000 WCDMA BAND5
0X80 GSM1800
0x300 GSM900
0X400000 WCDMA BAND1
0X2000000000000 WCDMA BAND8
0X400000 WCDMA BAND1
0X4000000 WCDMA BAND5
0X8000000 WCDMA BAND6
0X2000000000000 WCDMA BAND8
0X1000000000000000 WCDMA BAND19

Example of calculation :

# 2100MHz (B1) / 1800MHz (B3) / 2600MHz (B7) / 800MHz (B20) / 700MHz (B28)

Cara Hitung : 

0X8080045 =[0X01(LTE BAND1)+0X04(LTE BAND3)+0X40(LTE BAND7)+0X80000(LTE BAND20)+0X8000000 (LTE BAND28)

0X-------01 +
0X-------04 +
0X-------40 +
0X--80000 +
0x8000000 +
----------------------- =
0x8080045
