Flash by U-Boot TFTP method:
- Configure your PC with IP 192.168.1.2
- Set up TFTP server and put the factory.bin image on your PC
- Connect serial port(rate:115200) and turn on AP, then interrupt "U-Boot Boot Menu" by hitting any key
   Select "2. Upgrade firmware"
   Press enter when show "Run firmware after upgrading? (Y/n):"
   Select 0 for TFTP method
   Input U-Boot's IP address: 192.168.1.1
   Input TFTP server's IP address: 192.168.1.2
   Input IP netmask: 255.255.255.0
   Input file name: openwrt-ramips-mt7621-asus_rt-ax53u-squashfs-factory.bin
- Restart AP aftre see the log "Firmware upgrade completed!"
