Flash:      ESMT F50L1G41LB (128 MB)
Ethernet:   MediaTek MT7531AE + 2.5GbE MaxLinear GPY211C0VC (SLNW8)
Ethernet:   1x2.5Gbe (WAN/LAN 2.5Gbps), 4xGbE (WAN/LAN 1Gbps, LAN1, LAN2, LAN3)
WLAN 2g:    MediaTek MT7976GN
WLAN 5g:    MediaTek MT7976AN

Installation (UART)
Place OpenWrt initramfs image on tftp server with IP 192.168.1.2

Attach UART, switch on the router and interrupt the boot process by pressing 'Ctrl-C'

Load and run OpenWrt initramfs image:

      tftpboot initramfs-kernel.bin
      bootm

!!Attention!! is very important! After entering OpenWrt, please set / update the environment variables:

fw_setenv bootargs "ubi.mtd=ubi0 console=ttyS0,115200n1 loglevel=8 earlycon=uart8250,mmio32,0x11002000 init=/etc/preinit"
fw_setenv mtdids "spi-nand0=spi-nand0"
fw_setenv mtdparts "spi-nand0:2M(boot),1M(u-boot-env),50M(ubi0),50M(ubi1),8M(userconfig),4M(tp_data),8M(mali_data)"
fw_setenv tp_boot_idx 0

Run 'sysupgrade -n' with the sysupgrade OpenWrt image from console or Luci WebUI.

Recovery

Press Reset button and power on the router
Navigate to U-Boot recovery web server (192.168.1.1) and upload the OEM firmware

| WLAN 2g | 00:eb:xx:xx:xx:be | label     |
| WLAN 5g | 00:eb:xx:xx:xx:bd | label-1   |
+---------+-------------------+-----------+
label MAC address was found in UBI partition "tp_data", file "default-mac".
OEM wireless eeprom is also there (file "MT7986_EEPROM.bin").
