1. 下載breed,
地址 http://breed.hackpascal.net/
2. 下載小米Mini的開發板rom,
地址 http://www1.miwifi.com/miwifi_download.html
3. 通過web登錄小米Mini的后台, 路由器設置->升級檢測->手動升級, 提交剛才下載的rom
4. 下載小米無線的手機app, 連上小米Mini, 根據提示, 綁定路由器
5. 用同樣的小米賬號, 登錄 https://d.miwifi.com/rom/ssh , 下載刷機工具包 miwifi_ssh.bin
6. 安裝工具包
將下載的工具包bin文件復制到U盤（FAT/FAT32格式）的根目錄下，保證文件名為miwifi_ssh.bin；
斷開小米路由器的電源，將U盤插入USB接口；
按住reset按鈕之后重新接入電源，指示燈變為黃色閃爍狀態即可松開reset鍵；
等待3-5秒后安裝完成之后，小米路由器會自動重啟
7. 要等好一會兒, 一分鍾左右, 就能通過22端口登錄ssh了, 需要用之前給的root密碼
8. 備份
root@XiaoQiang:~# dd if=/dev/mtd0 of=/extdisks/sda1/xiaomi_rom_backup/all.bin 32768+0 records in 32768+0 records out root@XiaoQiang:~# dd if=/dev/mtd1 of=/extdisks/sda1/xiaomi_rom_backup/bootloader.bin 384+0 records in 384+0 records out root@XiaoQiang:~# dd if=/dev/mtd2 of=/extdisks/sda1/xiaomi_rom_backup/config.bin 128+0 records in 128+0 records out root@XiaoQiang:~# dd if=/dev/mtd3 of=/extdisks/sda1/xiaomi_rom_backup/factory.bin 128+0 records in 128+0 records out root@XiaoQiang:~# dd if=/dev/mtd4 of=/extdisks/sda1/xiaomi_rom_backup/os1.bin 25600+0 records in 25600+0 records out root@XiaoQiang:~# dd if=/dev/mtd5 of=/extdisks/sda1/xiaomi_rom_backup/rootfs.bin 22716+1 records in 22716+1 records out root@XiaoQiang:~# dd if=/dev/mtd6 of=/extdisks/sda1/xiaomi_rom_backup/os2.bin 4096+0 records in 4096+0 records out root@XiaoQiang:~# dd if=/dev/mtd7 of=/extdisks/sda1/xiaomi_rom_backup/overlay.bin 2048+0 records in 2048+0 records out root@XiaoQiang:~# dd if=/dev/mtd8 of=/extdisks/sda1/xiaomi_rom_backup/crash.bin 128+0 records in 128+0 records out root@XiaoQiang:~# dd if=/dev/mtd9 of=/extdisks/sda1/xiaomi_rom_backup/reserved.bin 128+0 records in 128+0 records out root@XiaoQiang:~# dd if=/dev/mtd10 of=/extdisks/sda1/xiaomi_rom_backup/bdata.bin 128+0 records in 128+0 records out root@XiaoQiang:~# dd if=/dev/mtd11 of=/extdisks/sda1/xiaomi_rom_backup/firmware.bin dd: can't open '/dev/mtd11': No such file or directory
9. 用winscp上載剛才下載的 breed-mt7620-xiaomi-mini.bin 到 /tmp 目錄
10. 執行 mtd -r write /tmp/breed-mt7620-xiaomi-mini.bin Bootloader, 等待設備自動重啟
11. 掉電, 按住reset, 加電
各種ROM的測試
