Woo hoo! My Axim X51v had, after a period where I hadn't gotten to use it for awhile, developed an issue with not responding to input from the screen or the buttons. I couldn't even hard reset for some reason. Lacking a way to fix it, I left it alone until I had a thought tonight. I grabbed it and decided to see if I could get it into bootloader mode, and force a manual reflash. Except, I pushed the wrong buttons, and put it in diagnostic mode instead. I decided to play along, and to my surprise all the diagnostics turned up fine. It clean-booted, and now it works again. I should be annoyed, the way I usually am when problems go away inexplicably. But I'm just happy that I've got the thing back.
