I'm trying the process of creating a new image. I've copied the /opt within the image to my drive and used mkcramfs to build my new_opt.img. However, when I attempt to flash the image (option 4, option 6) I get the message: /tmp/self_upgrade/new_opt.img not found. I also tried flashing the image built with option 5, with the same result. The image file is in the root of the sd card.

Edit: I think my problem is with the image file I created.

6258688: new_opt.img (original, created by make_opt.sh)
6254592: new_opt.img (created by mkcramfs, linux, ubuntu 8.04)

Note the filesize difference. I didn't pass any extra parameters to mkcramfs, just: mkcramfs new_opt/ new_opt.img.
