A quick question.
Your new link for 3.06 contains a flash_image file but it isn't zipped. The old link for 2.2.1 contains a flash_image.zip file. Since your instructions indicate that the zip file must be unzipped, I'm a bit confused as there is no zip file for 3.06.
I compared the MD5 checksums for the 3.06 and 2.2.1 flash_image files and they are different.
Has the flash_image been updated for 3.06? Is there something wrong with the download?
