I don't think there is a modem mode in K4203 but you can try enabling HuaweiAltModeGlobal in /etc/usb_modeswitch.conf and see what that switches the dongle into.

12d1:1590 is an id the dongle get after switching, you can not switch further on that usb id.
If you want to switch from the cmdline then disable automatic switching by usb_modeswitch or whatever other program that has switched it into 12d1:1590.

No it didn't switch, 12d1:1f1c is the initial id before the dongle is switched.
You can now use that id on the cmdline and the alt-mode switch and see what you get after it switched.

There is no "going back" after the initial mode switch. You have to re-plug the device.
