Did they replace your oscilloscope?
KedasProbe:
I updated my DHO914S, I see that after updating I lost my limited 250MHz BW.
Not really a big loss I expected it to be gone any moment anyway.
The calibration file cal_vertical.hex is now 3.5 times as big: from 201kB to 701kB (after required calibration)
(I also have one of 526kB in the default folder, before it was also 201kB)
BTW I also noticed that the option to update online was available (red dot on the R menu icon), I didn't do that, I did it from USB.

After the update of my DHO914S the name and content of the key file changed.
before: Key.data after: RKey.data
Both are still 148 Bytes
vendor.bin didn't change.

Yes. Recent firmwares "upgrade" your Key.date file for you. If you want to install older firmwares you have to put back the original Key.date.
If your 'scope is new and you don't have a Key.data then make a backup of RKey.data + vendor.bin.
...or just copy the whole of /rigol: adb pull /rigol/.
Point of this post: With those two files you can always manage to create a working SD card - there's card images out there and the only difference is two files.
