Quoted from ScottinSGFNY:OK - when I do that without the thumb drive installed It tells me to flip Switch #8 ON which I did, then press Select to Reboot which I did, then The DMD Shows Game code update
REBOOTING...
and hangs there.
any ideas?
Yep...that sounds messed up. What should happen is you press select to reboot and you should get an update icon on the DMD. You select it and it asks you to put in the usb drive. Then it recognizes the USB drive and sees the code revision. Then you select it and then it asks if you want to verify it first (I select no) then it begins to erase the old code and the write the new code.
I've never had any issues.
UPDATE: Thinking about it....it sounds like your Boot ROM isn't booting. You might want to power off and make sure the boot ROM chip is seated well.
The boot ROM isn't used normally in the game, so if you haven't updated before it could be the issue and go unnoticed until an update is attempted. It's basically a chip that is only used to start the game to do an update.
