mediatek: add support for Zbtlink ZBT-Z8102AX v2 Specifications: SoC: MediaTek MT7981B RAM: 1024MiB Flash: SPI-NAND 128 MiB Switch: 1 WAN, 4 LAN (Gigabit) USB: two M.2 slots for 5G modems via USB 3.0 hub, external USB 3.0 port Buttons: Reset, Mesh Power: DC 12V 1A WiFi: MT7976CN UART: 115200n8 UART Layout: VCC-RX-TX-GND Installation: 1. Power down the router and hold in the Reset button. 2. While holding in the button power up the router again. 3. Hold the button in for 10 seconds and then release. 4. Use your browser to go to 192.168.1.1 5. If you see a GUI that is for flashing firmware then you have the V2 model. If there is no GUI and the router continues to boot up normally you have the V1 model. 6. Now use the V2 sysugrade file. Note: Recovery GUI it can be used to recover from an incorrect firmware flash.
