Zte Mf65m Upgrade To 4g Today
Even if one were to replace the firmware (which is not user-accessible without specialized JTAG or flash tools), the proprietary 3G modem firmware and binary drivers are hardcoded. No open-source or alternative firmware (e.g., OpenWrt) exists for this device that can enable 4G, because the underlying modem is physically incapable of 4G transmission.
If you require 4G speeds, the only solution is to purchase a 4G-capable pocket WiFi (such as the ZTE MF65+, MF910, or MF920). zte mf65m upgrade to 4g
