Hi Jan, yes this was one of the 02B shields from the original Kickstarter.
I managed to recover one of mine now by doing the following:
- Downgraded from A09-06 to A07.03 - did not work
- Downgraded to A03.02 - did not work
- Flashed A03.02 again with "Write config" checked - NOW IT WORKED!
- Flashed A07.03 with "Write config" checked - still works
- Flashed A09.06 with "Write config" checked - still works
I think the problem occurs when upgrading from A03.02 directly to A09.06. It seems devices that had A07.03 upgraded fine, but I am not sure.
