Installation:
Bootloader won't accept any serial input unless "boot_wait" u-boot
environment variable is changed to "on".
Vendor firmware won't accept any serial input until "uart_en" is
set to "1".
Using the https://github.com/acecilia/OpenWRTInvasion exploit you
can gain access to shell to enable these options:
To enable uart keyboard actions - 'nvram set uart_en=1'
To make uboot delay boot work - 'nvram set boot_wait=on'
Set boot delay to 5 - 'nvram set bootdelay=5'
Then run 'nvram commit' to make the changes permanent.
Once in the shell (following the OpenWRTInvasion instructions) you
can then run the following to flash OpenWrt and then reboot:
'cd /tmp; curl https://downloads.openwrt.org/...-sysupgrade.bin
--output firmware.bin; mtd -e OS1 -r write firmware.bin OS1'
