Here is a little tutorial:
1. Download your zip file;
2. Copy zip file on the root of your SD Card;
3. Reboot your phone on custom recovey TWRP or CWM
4. Go to install and browse for SD Card. There you will find your modem software in zip file.
5. Install the modem
6. Reboot your phone and wait for the GSM signal to appear;
7. If your signal is no good repeat steps 1 to 6 with another one.
Allways make backup !
