[OpenWrt-Devel] [PATCH][RESEND.3] ar71xx:stops qihoo c301 booting into backup firmware

[swigger]

Flashing back to OEM through OpenWrt's sysupgrade process is also OK,
but you should cut-off extra seama header from the decrypted OEM
firmware.
then just run:
mtd -r write your-decrypted-oem-firmware firmware
