Hardware
--------
SoC: MediaTek MT7621AT
WiFi: MediaTek MT7603 bgn 2T2R
MediaTek MT7615 ac 4T4R
Flash: 32M SPI (Macronix MX25L25635F)
RAM: 128M DDR3 (Winbond W631GG6KB)
LED: Dome (Blue / White)
BTN: Reset
Installation
------------
These instructions were written for firmware version v3.9.27.
Downgrade if necessary.
1. Copy the OpenWrt sysupgrade image to the devices /tmp folder
via scp. On factory defaults, user and password is "ubnt" at
192.168.1.20/24.
2. Write the bootselect flag. Otherwise, the device might boot from the
wrong partition. Verify the mtd partition used in the command below
is the one labled "bs" in /proc/mtd (as this might change in the
future).
> dd if=/dev/zero bs=1 count=1 of=/dev/mtd4
3. Write the OpenWrt sysupgrade to the mtd partitions labled
"kernel0" and "kernel1".
> dd if=/tmp/openwrt-sysupgrade.bin of=/dev/mtdblock6
> dd if=/tmp/openwrt-sysupgrade.bin of=/dev/mtdblock7
4. Reboot or powercycle the device.
