Flash instruction
-----------------
1. Set up a TFTP server (IP address: 192.168.11.10)
2. Rename "initramfs-fit-uImage.itb" to "WTR-M2133HP-initramfs.uImage"
   and put it into the TFTP server directory.
3. Connect the TFTP server and WTR-M2133HP.
4. Hold down the AOSS button, then power on the router.
5. After booting OpenWrt initramfs image, connect to the router by SSH.
6. Transfer "squashfs-nand-factory.ubi" to the router.
7. Execute the following commands.
    # ubidetach -p /dev/mtd15
    # ubiformat /dev/mtd15 -f /tmp/openwrt-ipq40xx-generic-buffalo_wtr-m2133hp-squashfs-nand-factory.ubi
    # fw_setenv bootcmd bootipq
8. Perform reboot.

Recover to stock firmware
-------------------------
1. Execute the following command.
    # fw_setenv bootcmd bootbf
2. Reboot and wait several minutes.
