ramips: Add support for Xiaomi Mi Router(Black,R2100) The Xiaomi Mi Router AC2100 is a *black* cylindrical router that shares many characteristics (apart from its looks and the GPIO ports) with the 6-antenna *white* "Xiaomi Redmi Router AC2100" See the visual comparison of the two routers here: https://github.com/emirefek/openwrt-R2100/raw/imgcdn/rm2100-r2100.jpg Specification of R2100: - CPU: MediaTek MT7621A - RAM: 128 MB DDR3 - FLASH: 128 MB ESMT NAND - WIFI: 2x2 802.11bgn (MT7603) - WIFI: 4x4 802.11ac (MT7615) - ETH: 3xLAN+1xWAN 1000base-T - LED: Power, WAN in Yellow and Blue - UART: On board (Don't know where is should be confirmed by anybody else) - Modified u-boot Hacking of official firmware process is same at both RM2100 and R2100. Thanks to @namidairo Here is the detailed guide Hack: https://github.com/impulse/ac2100-openwrt-guide Guide is written for MacOS but it will work at linux. needed packages: python3(with scapy), netcat, http server, telnet client 1. Run PPPoE&exploit to get nc and wget busybox, get telnet and wget firmware 2. mtd write openwrt-ramips-mt7621-xiaomi_mi-router-ac2100-kernel1.bin kernel1 3. nvram set uart_en=1 4. nvram set bootdelay=5 5. nvram set flag_try_sys1_failed=1 6. nvram commit 7. mtd -r write openwrt-ramips-mt7621-xiaomi_mi-router-ac2100-rootfs0.bin rootfs0 other than these I specified in here. Everything is same with: https://github.com/openwrt/openwrt/commit/f3792690c4f0567a8965d82898295b9d50c3bb7e Thanks for all community and especially for this device: @Ilyas @scp07 @namidairo @Percy @thorsten97 @impulse (names@forum.openwrt.com) MAC Locations: WAN *:b5 = factory 0xe006 LAN *:b6 = factory 0xe000 WIFI 5ghz *:b8 = factory 0x8004 WIFI 2.4ghz *:b7 = factory 0x0004 |
