Hi could someone please tell me if it is possible to delete the firmware? Is there two jumpers that you could short or something like that?
My Problem is My LCD 2004 has two black lines and that's it! The control knob does nothing! If I connect it to my computer it doesn't change!
I have tried to use Hyper terminal but that just sais "object Jumped" or something like that.
The firmware that I tried to put on when it all went wrong is Rostock301 V1.0.02 I believe this is the correct version..
Thanks in advance
Percy
