Note: This Firmware has been provided to DP832 (non A) users by Rigol for those that had requested a FW Update for their units.
Ref. RIGOL DP832 Power Supply - firmware upgrade, « Reply #36 on: Yesterday at 03:38:23 AM » Although I don't think Rigol supplied this particular person his FW 09.

In the post you reference, Sebastian states "the Riglol Keys don't work" --- which is no different from 01.08 where they didn't work either (and why people downgraded to 01.06 to install the keys and then upgraded to 01.08).
How exactly are you concluding "all options lost"?

The trick with getting the options in 1.06 and then upgrading to 1.08 never worked for me. If I would install all the options in 1.06 and upgrade to 1.08 everything would be lost, not just the trigger option as other people here report for there units. If I would then go back to 1.06 the options would be there again without entering the codes again.
FW1.09 is essentially the same as 1.08, none of the bugs are fixed, the only difference is that you can not flash older versions anymore because of the new bootloader,

I would generally be suspicious of any Rigol firmware that comes in two separate sections to load - one following the other: you can pretty much be certain that the bootloader is being changed.

Yeah, I'm plenty suspicious. I feel for Rigol; they're in a hard place right now. I guarantee there is an engineer or two on their staff that raised a bit of a stink about how easy this stuff would be to compromise, and he was probably dismissed out of hand, and laughingly compared to "Dwight" in the local production of "The Office."
I will admit to using the keygens. I will also admit that if they fix the holes and produce firmware that i can't do without, I will upgrade to that firmware, even if it means losing the options I've hacked for myself. The thing is, I purchased the options I needed, and hacked the ones I want to play with. If any of those options I don't need become options I do need, then I'll buy those, too.

This, i ended up ordering the deep memory option because i do a lot of very large serial captures. I think anyone who uses hacked options at work is just asking for trouble, i'd hate to be the guy who keeps finding "glitches" on a high speed bus because of some ADC error caused by messed up software. :palm:

Hi all
I just bought a DS2072A (an upgrade from my siglent) and it cost me $1,300 with shipping to south africa, yes it wrecked my wallet.
vie been learning the in and outs of the scope and haven't touched the decoders yet, my time trial is almost over about 3 hours left! can anyone give me a cost breakdown of the decoders ??
why did Rigol not make the time-trial run when in use only. !!??
