D100 does not boot anymore

[Erwin]

Hello Dynon-lovers,

I tried to update my D120 and my D100 to firmware 4.0 and failed with the D100

After successful updating the D120 I did not get to the point to update the firmware of the D100.

This is what I did:

1. Firmware backup
2. Configure Checklists and saved the checklists to disk
3. Retrieve logged data

At the third point I got an error message stating that the firmware used in the EFIS is not able to save logged data. I think, this is OK.

After these three steps, the EFIS shows always the blue screen with the Dynon-Logo. Serial communication is not possible, no response while pressing any button.


I'm confused, because I did the same sequence with the D120. And there it worked pretty well.

Do you have any suggestions? Does it help to disconnect the internal backup-battery?

Thanks in advance

Erwin

The sequence of steps you took wouldn't have sent any data to the EFIS, so it doesn't sound like a firmware load that went wrong.

Disconnecting and reconnecting all power, including the internal battery, will confirm whether or not something is wrong with the unit though. If you get through that and the unit still isn't booting up correctly, we'll need to take a look at it here.

Hello dynonsupport,

thank you for your reply and yes, I agree not having changed anything in the firmware. To disconnect the internal battery I have to dismount the unit and I do not have this 7/64 inch Allen wrench. I contacted every tool-dealer in my surrounding with zero success. Unfortunately FlightDesign does not include this wrench with their CTSW shipment.

So it will take a little time to check, if unpowering the unit will solve the problem.

Kind regards

Erwin

I tried to disconnect the unit from all power with no success. After disconnecting the internal battery I waited about half an hour before reconeccting the power. Unfortunately no success

The unit is on the way to you.
