WL-500g Premium

[bmork]

Is there any way to backup the original firmware on the Premium?

I haven't got the Premium yet, but the following method works on a WL300g:

Use the hidden admin page at http://192.168.1.1/Main_AdmStatus_Content.asp to run this command:

dd if=/dev/mtd/1ro of=/var/tmp/display.jpg

Then just download the firmware from http://192.168.1.1/display.jpg

This works because there is a dangling symlink from /www/display.jpg to /var/tmp/display.jpg, maybe intended for the webcam application?

You might want to check this with ls before issuing the dd command...

Two additional notes:
- The http server can't be trusted. I had to make several attempts to get the complete image.
- The downloaded image will end with a lot of "ff" data, caused by the empty flash area at the end (before the nvram partition). This is not part of the image and should probably be deleted before reflashing

No guarantees whatsoever
