Spitz X-3000 install vanilla openWRT

Following the instructions in the links below, I was able to install openWRT vanilla in the Spitz X-3000, using the Snapshot image from the link below, I installed luci-ssl and luci-proto-modemmanager, I was able to connect to the luci web interface as well. Then I connected the WAN ethernet interface to the internet (existing internet) and I connected a client via the second ethernet port and all worked fine browsing the internet.

Now I have to enable the 5G modem/interface, I am not an expert in openWRT, please I need some detailed guidance (for noobs) on how to activate the modem in 5G mode instead of the ethernet WAN interface (used only for testing).

When I try to run the command minicom -D /dev/ttyUSB2 as explained on the commit information, it says command not found.

Without detailed instructions or at least some hints it will be really hard for me to make it work as a 5G modem, same as the original GL.iNet firmware.

Thank you very much

Hi,

May I know why you require to install original OpenWRT firmware?
The X3000 built-in Quectel Modem, and GL firmware has been adapted with Quectel Driver, to bring the modem works well. We are not recommended switching the firmware to others, and GL firmware also support Luci.

Because your FW is 2-3 versions behind, 21 vs 23, soon 24, that means security patches that you might be missing, do you have plans to update to the current version of the openWRT FW? Thanks

The OP21 firmware is also very secure at present.

If there are any security vulnerabilities, GL will evaluate and patch them in a timely solve or upgrade to a new OP version.
Currently, there is planning to update the OP version for X3000, but the time has not been determined yet.
