Hi, new to the forum, 1st post. here's my problem. We recently purchased a s250 in addition to our 743. well, i was messing with the functions in the panel, and, in the owner utilities i came across a function that asked, "do you wish to downgrade?", well since i was just sitting there waiting on the truck to get back, i pushed yes, and the machine shut off, and when i powered it back up, none of my passwords worked, now it's sitting in someone's driveway, and bobcat was closed when it happened, and they are closed tomorrow. i need some helpasap if anyone knows about this, please!!, i also removed the pos. side of the battery and anything else i could to reset the machine. thanx.
