Hi Oliver,

as already said, I tried to send the device to you, but yesterday it came back. I found your company's postal address on this site: https://www.foolography.com/contact/. Is that somehow outdated?

Alright, I kept trying it for a few more times - the problem is still the same. Gonna send it to you guys tomorrow.
Thanks for being honest, transparent and helpful!

Hi Oliver, thanks for your reply and sorry for being unresponsive for such a long time. I finally managed to record a videoclip of the upgrade process failing and put it on youtube.

While trying to update the firmware of my unleashed (C2) it completes C and B but fails on A. I tried on iOS (iPhone X) and Android (P20 Pro), took out the cam (5D III) battery to reset, tried to forget the unleashed in the app, reinstalled the app. Any hint what else I could try to update? Firmware...
