Looking for firmware and guidance on RG200U-CN

Hello, I’d recently bought a 5G modem from an Online seller who on the specification sheet used the processor UDX710. (model number: MF5605, there is no brand. my model has no lcd)

The firmware is old and the web UI is of poor quality.

I checked with ADB and found it used a UDX710.
On IMEI lookup, it came up as a QUECTEL RG200U-CN.

The web UI has automatic OTA updates, but the service appears to have shut down since it says that the network couldn’t be connected, although the network is clearly connected.

I will appreciate any help, thanks.

Please check the firmware version in your side currently. Thx
