Flash Global Firmware H122-373

I want my H122-373 running on the latest global firmware so every feature becomes accessible, not just the ones my current region-limited build exposes. My end goals are clear: after the flash the unit must support VoLTE and give me manual control to lock it to the LTE bands I specify. The job covers: • Supplying or sourcing a clean, verified global firmware package for the H122-373 • Guiding me through a safe flashing process (remote desktop or detailed step-by-step instructions are both fine) • Ensuring the new build boots correctly, retains IMEI/MAC, and activates the extra menus that let me: – Toggle VoLTE on/off – Select and hold specific LTE bands I can provide current firmware details, serial, and any diagnostic screenshots you need before we begin. The work is complete when I confirm the router operates on the global firmware, VoLTE registers on my carrier, and band locking sticks after a reboot.
