IMPORTANT !! Don't use the old firmware with the new Opus !
Very important message: I've heard from MichaŽl Dahan (of Bookeen) that the reason the firmware updates are not currently available on the site is that the old versions (1.5 Build 1093 & 2.0 Build 1094) are NOT COMPATIBLE with the new colour Opus, and can brick the device, because the new Opus is not using the same hardware as the old Opus.
So please DO NOT INSTALL THE 1.5 OR 2.0 FIRMWARE ON YOUR COLOR OPUS !!!
A NEW firmware update which will be compatible with ALL Opus models will be available on Bookeen's site in the very near future.
