I could not get my F500BT to boot in Test mode the way you have tried either. Try downloading LeetLauncher from here http://avic411.com/forum/viewtopic.php?t=18522 and then going into test mode through that.

I check this leetlauncher and i can't boot in testmode. I have same situation now it will show the pioneer start screen, flash white then turn off.

Sorry mate, I only have limited knowledge on this - what I have told you I did, worked for me! I'm sure someone who knows more will be here soon to tell you more.

I hope you manage to get this sorted out.
