@maurer after the fresh flash the router is not detecting automatically the modem (in ECM mode). I partially solved the issue adding: Kernel Modules → USB Support → kmod-usb-net-cdc-ether + kmod-usb-net-cdc-subset during compilation. But the modem get online when you force the wan to use usb0. I suppose your porting for zbt 8102 ax v2 (nand variant) is not affected. Correct?

most standard images don't come with the packages required for any kind of LTE modem.
add usb0 to the wan firewall zone, do you have wired wan hooked up at the same time ?
could you guide to accomplish this tip? thanks in advance
don't have access to any openwrt device at the moment, in the modem interface you've set up, there's a list box with zone assignment, it should be wan.
Please start from showing the output from cat /sys/kernel/debug/usb/devices

You need to follow https://openwrt.org/docs/guide-user/network/wan/wwan/ethernetoverusb_cdc
I suggest you search Quectel forum for information on IP passthrough configration with this modem.
Alternatively you can try switching the modem to MBIM or QMI and follow https://openwrt.org/docs/guide-user/network/wan/wwan/ltedongle
This may require updating your modem firmware.
hi @andrewz, i succesfully solved the issue. setting manually those commands. i wonder if same result can be achieved througt uci-defaults at first boot or hardcoded into firmware compilation. any tip for this?
