Done a update on my samflex440ep stated to load now I get is
AOS4 FLB
FLB:No SLB found in any of the designated boot sources; returning to u-boot. press any key to contiune.
Than I press any key and got this ] Than I reset but still have the same problem.
It's unlikely to be "DEAD", rather some settings just got reset with the firmware update.
I get the impression that you're new to the system. If so, I'd advice you to stay away from major updates or actions that require some more experience. Try to learn the system by using the provided applications and tools and familiarize yourself with the OS and its concepts. Post to various forums and ask the questions (there are no stupid questions). Only once you've gained some confidence go on with some of the more advanced topics such as upgrading firmware or tuning firmware variables.
I believe you'll save a lot of headache and aggravation this way.
