I didn't, although I have an official key for the normal options; I just used cybernets DSEA for CAN decode.
So I don't think it's necessary to uninstall and reinstall all (since I don't think the FW can distinguish between official and "non-official" key codes) unless you want to do it that way.

But, more importantly: Rigol has changed the the structure of unit settings stored in FRAM, so if you upgrade/downgrade between the major versions (v.01.XX.XX.XX to v.02.XX.XX.XX - or vice-versa), it's highly recommended to hold in the left-menu F6 button (sixth gray button down on left side of LCD) during the first reboot after loading (to clear FRAM) - otherwise the DSO will hang (often) when switching between various menu items.

Thanks for the very clear summary.  :-+
Didn't you add the 300M option, though?
Why not, in that case?

I wonder what it takes, we really need someone with the S model to have a look  :-/O

I've got a DS1074Z-S..

I wonder why you want to got back to the original state for RMA ...

what I mean is, what if the PSU has a problem, you can't switch it on then
or something similar, as in loose cooler clips that might shor-circuit something ...

Happy to help. I haven't installed the 300MHz option yet because:

1) I don't really need the extra bandwidth at this time - although maybe later, in which case I would try it.
2) I'm not 100% sure that HW v.1 fully supports it. Remember, Rigol didn't start offering a 300MHz model until they had developed HW v.2. OTOH, the CAN option is all software.
3) Remember, it's a 2GSa/s scope. The DSO only does sin(x)/x interpolation at 1G & 2GSa/s - everything below that (<= 500MSa/s) uses linear interpolation - which really requires a sample rate >= 8x the highest frequency for a decent reconstruction. SO throwing 300MHz at the DSO, especially at slower sample rates is pushing the envelope. In actual fact, for best reconstruction (and lowest noise), you really should keep the 100MHz bandwidth filter on if you're fairly certain you don't have higher frequencies.
jkw13:
The DP832 downgrade/upgrade for me has made the output meters read wrongly and the
options are lost when going back to v1.08, they're there in v1.06.
Can not change this by re-calibrating (unless I'm doing it in the wrong order?)
Can anyone help? Bricked?
This is the latest model with large heatsink.
Please :-BROKE
Thanks
