## 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

	| Device        | URL                                                                                                |

	| :-:           | :-:                                                                                                |

	| 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  |

	| Xiaomi CR8809 | https://cdn.cnbj1.fds.api.mi-img.com/xiaoqiang/rom/cr8809/miwifi_cr8809_firmware_b814a_6.2.102.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.

	>

	> Here are some useful links:

	>

	>> https://forum.openwrt.org/t/adding-openwrt-support-for-xiaomi-redmi-router-ax6s-xiaomi-router-ax3200/111085/513

	>>

	>> https://openwrt.org/inbox/toh/xiaomi/xiaomi_ax3600#tftp_recovery

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

elif [[ "$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

```
