Hi Friends,
I am new here and this is my first Post, I am having Problem with my Toshiba e-Studio2550c. It stops working and shows on the following error F520. I tried to reset but not having the firmware. One of my Friend gave me the firmware and when I am trying to install 9+4 it shows Copy Signature file in USB.... Please if someone can help me in this problem. I'll be very thankful for your help.
with regards
