如升级后ssh被禁用可以用telnet登录，执行下面代码再次启用ssh在telnet下运行始下命令sed -i 's/channel=.*/channel="debug"/g' /etc/init.d/dropbear/etc/init.d/dropbear start

下载固件https://github.com/robimarko/openwrt/releases下载特定的ax3600固件 openwrt-ipq807x-generic-xiaomi_ax3600-squashfs-nand-factory.ubi

注意坑：1.不要在刷好后的openwrt中升级 openwrt-ipq807x-generic-xiaomi_ax3600-squashfs-nand-sysupgrade.bin，会变砖。解决方法是下载官方救砖工具：小米路由器修复工具 https://bigota.miwifi.com/xiaoqiang/tools/MIWIFIRepairTool.x86.zip，按步骤就可以修复。2.不要在刷好后的openwrt中升级一些新软件，会导致一系列问题，如不能dhcp等。

在ssh下运行如下命令nvram set flag_last_success=0nvram set flag_boot_rootfs=0nvram set flag_boot_success=1nvram set flag_try_sys1_failed=0nvram set flag_try_sys2_failed=0nvram set boot_wait=onnvram set uart_en=1nvram set telnet_en=1nvram set ssh_en=1nvram commit

这里有时是mtd12,有时是mtd13，运行一条命令就可以ubiformat /dev/mtd12 -y -f /tmp/openwrt-ipq807x-generic-xiaomi_ax3600-squashfs-nand-factory.ubiubiformat /dev/mtd13 -y -f /tmp/openwrt-ipq807x-generic-xiaomi_ax3600-squashfs-nand-factory.ubi

nvram set flag_last_success=1nvram set flag_boot_rootfs=1nvram commitreboot

返回原小米原厂固件fw_setenv flag_last_success 0fw_setenv flag_boot_rootfs 0reboot
