Device specification
--------------------
SoC: MT7628AN MIPS_24KEc @ 580 MHz 2.4G-bgn 2x2
WiFi: MT7612EN 5G-an, ac 80 MHz 2T2R
Flash: 16 MB
DRAM: 64 MB
Switch: MT7628AN (integrated in SoC)
Ethernet: 1 x 10 /100 Mbps
USB: None
Antennas: 2 x 2,4 GHz and 2 x 5 GHz (all are external and non-detachable)
LEDs: blue/red/amber
Buttons: Reset
Serial: 115200,8n1
MAC addresses as verified by OEM firmware:
------------------------------------------
use address source
LAN *:DD factory 0x28
WAN *:DD factory 0x28
2g *:DE factory 0x4
5g *:DF factory 0x8004
OEM firmware uses VLAN's to create the network interface for WAN and LAN.
Bootloader info:
----------------
The stock bootloader uses a "Dual ROM Partition System".
OS1 is a deep copy of OS2.
The bootloader starts OS2 by default.
To force start OS1 it is needed to set "flag_try_sys2_failed=1".
How to install:
---------------
1- Use OpenWRTInvasion to gain Telnet, SSH and FTP access: https://github.com/acecilia/OpenWRTInvasion
[IP: 192.168.31.1 | Username: root | Password: root | FTP-Port: 21]
2- Connect to router using telnet or ssh.
3- Backup all partitions. Use command "dd if=/dev/mtd0 of=/tmp/mtd0". Copy /tmp/mtd0 to computer using ftp.
4- Copy openwrt-ramips-mt76x8-xiaomi_miwifi-3a-squashfs-sysupgrade.bin to /tmp in router using ftp.
5- Enable UART access and change start image to OS1.
nvram set uart_en=1
nvram set flag_last_success=1
nvram set boot_wait=on
nvram set flag_try_sys2_failed=1
nvram commit
6- Erase OS1 & OS2 and install OpenWrt
mtd erase OS1
mtd erase OS2
mtd -r write /tmp/openwrt-ramips-mt76x8-xiaomi_miwifi-3a-squashfs-sysupgrade.bin OS1

New U-Boot version for MediaTek MT76x8/MT762x based ALFA Network boards
includes support for a 'dual image' feature. Users can enable it using
U-Boot environment variable 'dual_image' ('1' -> enabled).
When 'dual image' feature is enabled, U-Boot will modify DTB and divide
the original 'firmware' flash area into two, equal in size and aligned
to 64 KB partitions: 'firmware' and 'backup'. U-Boot will also adjust
size of 'firmware' area to match installed flash chip size.
U-Boot will load kernel from active partition which is marked with env
variable 'bootactive' ('1' -> first partition, '2' -> second partition)
and rename both partitions accordingly ('firmware' <-> 'backup').
There are 3 additional env variables used to control 'dual image' mode:
- bootlimit - maximum number of unsuccessful boot tries (default: '3')
- bootcount - current number of boot tries
- bootchanged - flag which informs that active partition was changed; if
it is set and 'bootcount' reaches 'bootlimit' value,
U-Boot will start web-based recovery which then updates
both partitions with provided image

As started in 19724e28c8 ("ramips: split base-files into
subtargets"), this moves some smaller left-over files to the
appropriate base-files folder of their subtarget:
- /etc/init.d/bootcount
- /etc/uci-defaults/04_led_migration
