Well, it's a good idea.
But I don't know how to create a wiki page.
QIhoo 360 C301 (http://luyou.360.cn/parameter.html, Simplified Chinese
ONLY), has two 16M flash.
The first flash is full functional, and the second has just a backup firmware.
U-boot will boot into the second flash when it believes firmware on
the first is broken.
To flash openwrt, disconnect power source, hold down the reset button
and power on, keep holding reset button for about 20 seconds.
Go to http://192.168.1.1 and upload the openwrt firmware to flash.
To flash back to OEM firmware from openwrt, use the same instructions
above and upload a decrypted OEM firmware which can be founded
somewhere by a search engine.
There is also some tools for decrypting OEM firmware (no tool for
encrypting yet), but they are not part of openwrt, so it is not
necessary to discuss here.
