MPC 2500 OS DATA ERRor !!!!!

I get a insert memory card OS UPDATE message. I made a mistake and ejected the memory card while it was loading sounds. Now I get a OS Data error message when I turn the unit on. I tried holding the erase, Ive tried everything. Can Some one help me!!??

Have you tried reinstalling your OS?

When I turn it on it is on an error page. The unit wont switch screens at all.

What did you do to solve this problem? because i have a similar problem.

Many thanks for your help and advice.

did anybody figure out how to fix the os data error problem… cause I'm having the same issue…. please help… god blessed

if you cant get the OS to re-initialize the installation again chances are you've corrupted onboard flash rom where OS is written to

can the onboard flash rom be fix?
