This is a stable, recent firmware build for the Huawei H122 platform. If you have successfully flashed it, you should have a reliable ONT with standard Huawei features enabled, free of specific ISP bloatware. If you are looking for the file to download, it is typically distributed within ISP technician circles or private forums (like 4pda) as it is not officially hosted on the public Huawei consumer site.
This process takes about 5-7 minutes. Do not power off during the update.
Before dissecting the firmware, a quick refresher on the hardware:
The device is a beast. But stock carrier-specific firmware often cripples its capabilities—limiting band selection, disabling bridge mode, or locking APN settings. This is where the universal firmware shines.
The Huawei 5G CPE Pro 2 (H122-373) firmware version 10.0.5.1(H612SP1C00) is a baseline software release for this Wi-Fi 6 router. While intended to provide stable 5G/4G connectivity, user reports for the 10.0.5.x series have highlighted significant performance and stability concerns. Key Features & Performance

Wi-Fi 6 Plus: Supports dual-band transmission (2.4 GHz & 5 GHz) with a peak rate of 2976 Mbps, utilizing 160 MHz bandwidth for compatible Huawei devices.
Antenna Technology: Features 5G Super Uplink to improve coverage and speed by combining TDD and FDD bands. Critical User Feedback on 10.0.5.x
Reviewers and users on the Huawei Community and Huawei Forums have noted several recurring issues:
Speed Degradation: Some users reported speeds dropping from 300-500 Mbps to under 2 Mbps immediately after updating to 10.0.5.1.
5G Connection Drops: A common complaint is the router defaulting to 4G even when a stronger 5G signal is available, or losing 5G connectivity entirely after the update.
Instability: In some cases (notably version 10.0.5.13), the router requires frequent restarts (twice daily) due to speeds stalling at near-zero. Regional & Update Constraints
