I tried flashing to OpenWRT openwrt-ramips-mt7621-zbtlink_zbt-we1326-squashfs-sysupgrade but it flashes and never comes back up for me to be able to get into the router.
I also tried flashing to ROOter openwrt-we1326v5-GO2020-03-01-upgrade but it does the same as above.

Anyone have any other suggestions?
In the debug it says /dev/ttyUSB2 Can't open device /dev/ttyUSB2.
In the connection log it says Modem #1 Connected (Quectel EM12-G)
Network status shows this:
Modem :
