| ## How to install | ||
|
|
||
| ### Get `UART` access | ||
|
|
||
| > Input from `UART` will be allowed after a successful `TFTP recovery`. | ||
| 1. Connect `UART` and `LAN`. | ||
|
|
||
| 2. Download the vendor firmware: | ||
|
|
||
| Offical website: https://www.miwifi.com/miwifi_download.html | ||
|

| | Redmi AX3000 | https://cdn.cnbj1.fds.api.mi-img.com/xiaoqiang/rom/ra81/miwifi_ra81_firmware_1dd69c_1.0.33.bin | | ||
| | Xiaomi CR8806 | https://cdn.cnbj1.fds.api.mi-img.com/xiaoqiang/rom/cr8806/miwifi_cr8806_firmware_fe70b_6.2.14.bin | | ||
| | Xiaomi CR8808 | https://cdn.cnbj1.fds.api.mi-img.com/xiaoqiang/rom/cr8808/miwifi_cr8808_firmware_9d216_6.2.11.bin | | ||

|
|
||
| 3. Use [`MIWIFIRepairTool`](https://bigota.miwifi.com/xiaoqiang/tools/MIWIFIRepairTool.x86.zip) to recover the device's firmware. | ||
|
|
||
| Offical tutorial: https://www.xiaomi.cn/post/19134127 | ||
|
|
||
| > This tool simply does `TFTP recovery`. You can use other `DHCP` and `TFTP` server as well. | ||

|
|
||
| 4. Hold the `reset` button and reboot the router until the `system` LED blink. | ||
|
|
||
| 5. Wait until the firmware being flashed. | ||
|
|
||
| 6. Unplug then plug back in the power. | ||
|
|
||
| 7. Send any key stroke to `UART` to interrupt the `U-boot`. | ||
|
|
||
| 8. Run the following command inside `U-boot`: | ||
|
|
||
| ```shell | ||
| setenv boot_wait on | ||
| setenv uart_en 1 | ||
| saveenv | ||
| ``` | ||
|
|
||
| Now we have enabled `UART`. | ||
|
|
||
| ### Flash Openwrt | ||
|
|
||
| #### a. Use `U-boot` to flash | ||
|
|
||
| Download [`openwrt-ipq50xx-arm-redmi_ax3000-squashfs-nand-factory.ubi`](https://github.com/hzyitc/openwrt-redmi-ax3000/releases/latest/download/openwrt-ipq50xx-arm-redmi_ax3000-squashfs-nand-factory.ubi) and put it into TFTP root. | ||
|
|
||
| Then run the following command inside `U-boot`: | ||
|
|
||
| ```shell | ||
| # This router ip | ||
| setenv ipaddr 192.168.1.2 | ||
| # TFTP server ip | ||
| setenv serverip 192.168.1.1 | ||
|
|
||
| # Download the firmware to the RAM | ||
| tftpboot openwrt-ipq50xx-arm-redmi_ax3000-squashfs-nand-factory.ubi | ||
|
|
||
| # Flash it as system 2 | ||
| flash rootfs_1 | ||
| setenv flag_try_sys2_failed 0 | ||
| setenv flag_boot_rootfs 1 | ||
| setenv flag_last_success 1 | ||
| saveenv | ||
|
|
||
| # Flash it as system 1 | ||
| # flash rootfs | ||
| # setenv flag_try_sys1_failed 0 | ||
| # setenv flag_boot_rootfs 0 | ||
| # setenv flag_last_success 0 | ||
| # saveenv | ||
|
|
||
| # Reboot | ||
| reset | ||
| ``` | ||
|
|
||
| #### b. Use `miwifi` (the vendor firmware) to flash | ||
|
|
||
| ```bash | ||
| cd /tmp | ||
| wget https://github.com/hzyitc/openwrt-redmi-ax3000/releases/latest/download/openwrt-ipq50xx-arm-redmi_ax3000-squashfs-nand-factory.ubi | ||
|
|
||
| # Check your partition table | ||
| # cat /proc/mtd | ||
| [[ "$(grep '"rootfs"' /proc/mtd | cut -d':' -f1)" == "mtd18" ]] || exit | ||
| [[ "$(grep '"rootfs_1"' /proc/mtd | cut -d':' -f1)" == "mtd19" ]] || exit | ||
|
|
||
| # Detect the current system slot and flash into the other one | ||
| # cat /proc/cmdline | ||
| mtd="$(grep -oE 'ubi.mtd=[a-zA-Z0-9\-\_]*' /proc/cmdline | cut -d'=' -f2)" | ||
| if [[ "$mtd" == "rootfs" ]]; then | ||
| # Flash it as system 2 | ||
| ubiformat /dev/mtd19 -f openwrt-ipq50xx-arm-redmi_ax3000-squashfs-nand-factory.ubi | ||
| nvram set flag_try_sys2_failed=0 | ||
| nvram set flag_boot_rootfs=1 | ||
| nvram set flag_last_success=1 | ||
| nvram commit | ||
| else if [[ "$mtd" == "rootfs_1" ]]; then | ||
| # Flash it as system 1 | ||
| ubiformat /dev/mtd18 -f openwrt-ipq50xx-arm-redmi_ax3000-squashfs-nand-factory.ubi | ||
| nvram set flag_try_sys1_failed=0 | ||
| nvram set flag_boot_rootfs=0 | ||
| nvram set flag_last_success=0 | ||
| nvram commit | ||
| fi | ||
|
|
||
| # Reboot | ||
| reboot | ||
| ``` | ||
