BACKUP YOUR STOCK FIRMWARE:
- Put openwrt-*-initramfs-uImage.itb to your
  TFTP server and rename it to initramfs.bin
- Enable serial console and enter to u-boot cli
  and exec these commands:
    ```
    tftpboot <your_tftp_server_ip>:initramfs.bin
    bootm
    ```
- Once boot completed and you get the openwrt shell
  execute below commands:
    ```
    device=ax850
    mkdir -p /tmp/fw_backup; cd /tmp/fw_backup
    rootfs=$(cat /proc/mtd | grep \"rootfs\" | cut -d: -f1)
    rootfs_1=$(cat /proc/mtd | grep \"rootfs_1\" | cut -d: -f1)
    dd if=/dev/${rootfs} of=rootfs_${rootfs} bs=1M
    dd if=/dev/${rootfs_1} of=rootfs_1_${rootfs_1} bs=1M
    cp /sys/firmware/fdt fdt.dtb
    md5sum * > md5sum
    tar -cvzf /tmp/${device}.tar.gz .
    sum=$(md5sum /tmp/${device}.tar.gz | cut -d' ' -f1)
    mv /tmp/${device}.tar.gz /tmp/${device}_${sum}.tar.gz
    echo "stock fw backup saved to: /tmp/${device}_${sum}.tar.gz"
    ```
- Upload/save your backup to a safe place.

STOCK FIRMWARE RECOVERY:
- Boot initramfs image
- Upload your backed-up stock fw tarball to the device
  using scp or download it from the device using wget.
- Enter device ssh cli or tty and exec:
    ```
    cd /tmp && wget <your_web_server_ip>/${stock_fw_backup}.tar.gz`
    tar -xpzf ${stock_fw_backup}.tar.gz
    rootfs=$(cat /proc/mtd | grep \"rootfs\" | cut -d: -f1)
    rootfs_1=$(cat /proc/mtd | grep \"rootfs_1\" | cut -d: -f1)
    ubiformat /dev/${rootfs} -y -f /tmp/rootfs_${rootfs}
    ubiformat /dev/${rootfs_1} -y -f /tmp/rootfs_1_${rootfs_1}
    reboot
    ```

INSTALLATION:
1. initramfs method
- Put openwrt-*-initramfs-uImage.itb to your
  TFTP server and rename it to initramfs.bin
- Enable serial console and enter to u-boot cli
  and exec these commands:
    ```
    tftpboot <your_tftp_server_ip>:initramfs.bin
    bootm
    ```
- Once boot completed and you get the openwrt shell
  execute below commands:
    ```
    cd /tmp && wget <your_web_server_ip>/factory.ubi`
    export rootfs=$(cat /proc/mtd | grep rootfs | cut -d: -f1)
    export rootfs_1=$(cat /proc/mtd | grep rootfs_1 | cut -d: -f1)
    ubiformat /dev/${rootfs} -y -f factory.ubi
    ubiformat /dev/${rootfs_1} -y -f factory.ubi
    reboot
    ```

2. u-boot factory.ubi image method
- Put factory.ubi to your TFTP server and
  enter u-boot cli and exec these commands:
    ```
    tftpboot <your_tftp_server_ip>:factory.ubi
    #After downloading is finished:
    flash rootfs
    flash rootfs_1
    reset
    ```
