OK,
My experience.
I have a 5072 - so I had a lot to loose by upgrading... I put a FAT32 formatted flash drive in and copied the calibration data. Just in case...
Just a note - moving the drive between the Rigol and the PC was not a happy thing. Win10 almost always has an issue with the drive after being in the scope.
I put the 01.01.04.04 firmware on the drive and the scope said it was corrupted.... Reformatted the drive, reloaded the firmware - all was well and it updated to 01.01.04.04.
As reported - I lost 2 channels, the AWGs.... Interestingly enough, in the acquisition menu it still showed 200M, but when changed - the 200M option disappeared.
I played with the SSH enable .GEL. Upon installing - my scope always says its corrupt. Tried and re-tried many times. I did finally checked, after it failed - and sure enough - it was working. So maybe the corrupt file warning is normal for this patch? I have not tried to go in and make it permanent - it appears that the patch just turns it on for this boot...
The patch for the license... I reformatted the drive again, Put the file on the USB drive, and selected it on the scope. No errors - it updated perfectly. Then it asked me to reboot - which I did......
My scope is back...!!!! All 4 channels, the 2 AWGs, 200M samples. I went to the license page - looks just as shown -- all enabled and permanent.
So bottom line - it worked here although I have some more work to do to make SSH on permanently.
FYI...
