Gain telnet access:
1. Login into web interface, and download the configuration.
2. Uncompress the configuration:
     * Enter fakeroot if you are not login as root.
   tar -zxf <filename>.tar.gz
3. Edit 'etc/passwd', remove root password: 'root::1:0:99999:7:::'.
4. Edit 'etc/rc.local', insert telnetd command before 'exit 0':
   ( sleep 3s; telnetd; ) &
5. Repack the configuration:
   tar -zcf backup.tar.gz etc/
6. Upload new configuration via web interface, now you can connect to
   KOMI A31 via telnet.

Flash instructions:
1. Connect to KOMI A31, backup everything, especially 'Factory' part.
2. Write new BL2:
   mtd write openwrt-mediatek-filogic-konka_komi-a31-preloader.bin BL2
3. Write new FIP:
   mtd write openwrt-mediatek-filogic-konka_komi-a31-bl31-uboot.fip FIP
4. Set static IP on your PC:
   IP 192.168.1.254/24, GW 192.168.1.1
5. Serve OpenWrt initramfs image using TFTP server.
6. Cut off the power and re-engage, wait for TFTP recovery to complete.
7. After OpenWrt has booted, perform sysupgrade.
