Jack stands are overkill, but yeah, tires do flatten out after months sitting.

...yeah I hear you on that, but you gotta admit the hand bar builds character. Or at least builds your arm into a weird Popeye situation. Did six hours on a honey locust last spring, turned out the "rock" I was cursing at was a buried cinder block from some old patio. Real confidence booster when you finally dig it out and just stare at it. Hydraulic auger sounds like cheating until you realize your back doesn't hate you the next day. But hey, at least with the manual bar you can feel exactly when you're about to nick that gas line, so that's something. Sort of.

Did you check if the new firmware changed the default comm settings on you? Tbh, I had a similar thing happen with a different brand and it turned out the update reset the baud rate to something the keypad hated. I just locked the old firmware file on the shop laptop and told the guys to load that until the next update, worked fine after that.
