Thanks for all the secret key reset features etc. But my ESQ'1 does not respond, I have rom version 2.20, could this make a difference? The problem is the key board never initializes, at boot up it stays on the first screen you see. So none of the buttons work there is nothing to select. I had the machine appart and replaced the battery, I also took apart the two boards under the display and buttons and cleaned it all up. While iI was in there I took an ohm meter and tested across the circuits of some of the buttons and they appear to work when depressed. I wonder if the roms are bad?
