Hi all,
We've just tried to upgrade our Ultra frame from 4.0.0.517 to 7.0.3.9205, twice, both time resulting in failure.
First time was via Dashboard, uploading the .ultra file from a PC via Dashboard to the frame. This resulted in the panel display saying, a little after clicking OK to upgrade, --Upgrade Mode--Upgrade Failed.
Second time was via the USB key with the .ultra file. We loaded it on Dashboard and clicked OK, after a little while the panel display saying --Upgrade Mode--Invalid Checksum.
At this point we cut our losses. Is there anything, obvious or not, that might cause this problem, and is there anything we can do to upgrade successfully?
Thanks,
Andrew.
