I don´t know what happened but today i was able to update the Firmware of my JBC DDE-2C from version 8886566 to 8886875 which is the latest firmware on the JBC server
what i did:i downloaded a fresh copy of the firmware from JBC, unzipped it on the USB stick that i have been using before (so no new USB Stick i already tried 9 different sticks) and plugged it in to my station.
The station then showed
Reading pendrive. Wait.. then i got a phone call and was about 10-15 minutes away, when i came back i started the firmware upgrade and this time it worked.
I really don´t know why it worked this time, the only two things i can imagine is either the station need more time to read the USB stick or they maybe changed the firmware on the server
EDIT:I checked the Firmware file and it is the same i downloaded 2 weeks ago, so no change from JBCI checked the menu of my station, no downgraded functionality all features are there
I feel so dumb right now
