My daughter's 5" EZ Reader beeped when she turned it on and then the screen began flashing repeatedly.
We tried reset.
We tried removing the battery.
As I searched the forums for help, it was Sunsparks post
here in this thread that solved the problem.
We reset the flash memory as indicated by holding down the left page turn button together with the power button.
It told us it would clean the flash memory and to hit ok.
It read a list of things:
invalid block 3
1. update kernel
2. update system
3. update logo
4. update parser app
5. update resource
and voila, my daughter danced off to finish her book.
I can't thank these forums enough but wanted to post in case someone else ran into a similar issue.
