Closed Extracting Firmware

[Bcon]

Hello everyone, I have two marvel chipped mifis that is M028T for both Vodafone Uganda(L02B) and Vodafone Cameroun(L02C). it beats my mind that the one of Cameroun is able to hike 4g on all networks and the one of Uganda only stops at 3g despite the fact that both mifis look similar and have same version(v005) of firmware installed. The only difference is the countries. I've been wondering and asking myself if there's away I can extract firmware from the one of Cameroun and flash it to the one of Uganda so that it can as well hike 4g on all networks.
