After MC-808 System Update Version 1.03 my MC 808 groovebox doesn't work anymore.
I put the Roland folder containing MC808UPD.BIN files on CompactFlash SanDisk 512MB and I inserted compact flash in MC 808, I followed the procedure with power on ... the update started ... 3 min ... The message COMPLETED appeared on the display.
I turned on the power, took out the card and restarted .... the message "Roland MC-808 sampling groovebox" appears on the screen and otherwise nothing works at all, I can't give "Factory Reset" , I can't press any button. ..nothing is all dead.
My MC 808 groovebox is like new, I only used it occasionally, maximum 20 hours of operation, otherwise it was in the bag and kept carefully.
Please help me!
Thank you in advance!

From the service manual...

If the update fails
• Turn off the power, and then turn it on again to execute the update again.
• If the update fails again, it is probably that the update card was not
created correctly. Please repeat the process of creating the update card,
and try the update again.
