Inventory turns can/will vary by dealer and location ... back in June, it appeared as though a subset of new owners were getting grills delivered to them from local dealers that were manufactured 6-11 months prior and had "vintage" firmware installed ... this issue has not been reported much lately, so hopefully what is currently available to purchase is running Firmware 02.00.01 at a minimum, as that is the most stable version of Firmware prior to the August 2020 release (02.01.03) ... getting the Firmware updated from 02.00.01 -> 02.01.03 should go smoothly, and may occur during your initial setup/pairing of WiFIRE ...
The Config Version update (second part of the update process) is the piece that can take anywhere from 12+ Hours to upwards of 2 weeks - patience is your only option (you need to leave the grill powered on continuously until the Config Version updates to 06.009) ...
Some folks have reported receiving Ironwood 650s with 02.00.01 | 06.009 pre-installed, but they can come with 02.00.01 | 06.008 (supports 500 degrees), or 02.00.00 | 06.007 (does not support 500 degrees until the Config Version is 06.008 or later) ... it is very doubtful at this point in time that you would receive a unit with 02.00.00 | 06.007, unless it was manufactured in Q4CY19 - you can verify the MFG Date via the attached photo example ...
Let us know what versions you have pre-installed after you unbox and do your initial power-up ...
