I tried to update my D-100 EFIS to 4.0 today, backed up the old version, had the unit powered from a fully charged battery, and the laptop with main power. Support program showed that the update completed sucessfully but the unit was powered off (screen black) and will not power back on. Tried disconnecting the internal battery as suggested in the help file and recycling the power but the unit will not power back on. Updated the EMS D-120 to 4.0 just fine.
EDC-10A is installed and was connected and detected by the support program.
Please advise what steps (if any) I can or need to take or do I need to return the unit to Dynon.
