After updating the firmware the unit will not power on except in “com” mode. Anyone else experience this? I have started in “com” mode and hit 7 to do a factory restore and unfortunately the result is unchanged… So regretting trying to update the firmware now!
Is it a new unit? If yes, they ship with a newer firmware / bootloader (v.220) that is incompatible with the currently downloadable update (v.218).
You can try this, but do it at your own risk.
