HUAWEI E3131-s2 problem..


I got a new usb modem HUAWEI E3131-s2(3G HSPA+) but it isn't recognized by my windows based gps application, only recognizes HUAWEI E3131-h2 (4G). Noticed is not a network data matter I wonder if is it possible flashing E3231-s2 with E3131-h2 firmware even it will be working on 3G network.
Thanks in advance.

Look, all depend of hardware, and little on software.
If hardware can supported 4G then you can reflash software, but firstly i recommeded check PCB for existed Power Amplifiers for all bands what you need.

And only after rewrite FW or NVM file for apply bands in software.
