Installation
-----------------
1. Telnet method
    a. Enable telnet
    Log in to http://192.168.10.1/ with the password on the sticker
    Modify URL according to example (keep your unique hash after ";stok=")
    and press Enter:
    http://192.168.10.1/cgi-bin/luci/;stok=78becad1b1490e45be2776025cde2b7d/api/NPCnetwork/ping?url=$(telnetd)
    You should get the following in the browser:
    {"link":0}

    b. Run tftp server on IP 192.168.10.254 and put factory image
    'openwrt-qualcommax-ipq50xx-cmcc_mr3000d-ci-squashfs-factory.ubi'
    in the tftp root dir.

    c. Login to 192.168.10.1 with telnet (user: root, pass: from the
    sticker).

    d. Download factory image from the tftp:
    tftp -l factory.ubi -r openwrt-qualcommax-ipq50xx-cmcc_mr3000d-ci-squashfs-factory.ubi -g 192.168.10.254

    e. Flash factory image:
    export rootfs=$(cat /proc/mtd | grep rootfs | grep -v _ | cut -d: -f1)
    ubidetach -f -p /dev/${rootfs}
    ubiformat /dev/${rootfs} -y -f /tmp/factory.ubi

    f. Reboot:
    reboot

2. U-Boot Method using UBI Image (using UART)
    a. Place the factory.ubi file on your TFTP server, enter U-Boot CLI
    and exec these commands:
    tftpboot <your_tftp_server_ip>:factory.ubi
    flash rootfs
    reset

3. U-Boot Method using initramfs Image (using UART)
    a. Place the openwrt-*-initramfs-fit-uImage.itb file on your TFTP
    server and rename it to initramfs.bin

    b. Enable serial console, enter to U-Boot CLI and exec these commands:
    tftpboot <your_tftp_server_ip>:initramfs.bin
    bootm

    c. Once boot completed, upload the sysupgrade.bin file to router's
    /tmp directory (using scp or wget) and execute the following command
    in openwrt shell:
    sysupgrade -n /tmp/sysupgrade.bin

MAC Addresses

Notes
-----
1. U-Boot is protected by a password (pass: netpower).
