Oh, you work for Tascam, do you? You should meet up with the Tascam engineer who reads and participates in this very forum at the watercooler someday and compare notes. (To my knowledge Tascam never "supported" any forum in any way but casual participation.)
BTW, your super-secret reset code is exactly what Jarno described (booting in diagnostic mode), and yes, it IS in the manual.
Look, if you have any valuable information, then share it. But if you have BS personal attacks to make because somebody hurt your widdle feelings, then you can bugger off.
But I will tell you this: mis-sharing "top secret" information and making snarky posts about forum members doesn't make you sound, as I'm sure you imagine it does, like a Big Time Insider Dude. On the contrary, it makes you sound like you live in your Mom's basement.
