CFE

To restore the netgear image run in CFE:

• ifconfig -auto eth0
• flash -noheader 192.168.0.5:netgear.img.1 flash0.os
• flash -noheader 192.168.0.5:netgear.img.2 -offset=3932160 flash0.os

"The CFE flash routine will only download and flash a maximum of 4194304 bytes (4MB) at a time. To get around the 4MB limit, we need to split the image into smaller chunks and then use the -offset flag to flash the two parts." [1]
