Same thing with stucking on the boot up screen.
Recently bought the new color version of Cybook Opus 400Mhz, and tried to install the 2.1 1198 firmware. After doing all the prescribed procedures, and "Update successful. Please turon the power on" I did what was told, but my Opus just stuck on the boot up screen with the red LED flashing. It was charged by that time. Plugging off the battery didn't work. The boot up screen with the pic of Cybook was still on the screen. Dunno what to do now. COntacted Bookeen on this issue, waiting for the answer.
Could someone advise, will installing of the old 2.0 firmware work?
