Product website: https://www.mi.com/miwifi3a 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 Credits: -------- This PR is based on the work of Zehao Zhang (Github: @ZZH-Finalize) that he had published in the PR: #15698 Signed-off-by: Olgun Demir <olgun.demir@mail.com.tr> Link: https://github.com/openwrt/openwrt/pull/18427 Signed-off-by: Hauke Mehrtens <hauke@hauke-m.de> |
