The internal LTE modem is a Quectel EG060W and needs the option driver
IDs added in a separate commit. gpio-export applies the initial output
value raw, ignoring the active-low flag, so output = <0> is what pulls
the modem power enable low and powers it at boot.
Migration to OpenWrt:
- Obtain the RSA signed intermediate firmware from Cudy:
openwrt-ramips-mt7621-cudy_lt700-outdoor-v1-squashfs-flash.bin
- Connect a computer to the LAN port and flash the intermediate firmware
via the OEM web interface
- OpenWrt is now accessible via 192.168.1.1
- Install the regular OpenWrt sysupgrade image from LuCI or over SSH
Revert back to OEM firmware:
- Configure a computer with IP 192.168.1.88 and run a TFTP server that
serves the OEM recovery image as recovery.bin
- Hold the reset button while powering on the device; the bootloader
fetches recovery.bin and restores the OEM firmware
