Command modification did NOT work as before!
I have try with many variations how to do.

With these units what I have before all goes ok.

I have not yet find solution with these new. If I try as before, display go sometimes "black" and only button what make anything is power ON/OFF. After this scope continues as DS1052E (serial number it (sometimes) keep as I type it, but it return to 1052). Some times there is only white random scratch over model number row from left to right over display.) One time it was totally difficult to return so that system display was ok.

FW with these new are exactly same 020202

Only difference what I can see is different start of serial number after letters. (first 4 digits... maybe these are some "prefix" what indicate some product revisions?

So I think we need continue more public discussions to push factory make good stop for modifications. We can teach them to do hack proof scopes. Maybe they make nearly "waterproof" next revision. (or this what I have now is just this)

Wow, are you saying that Rigol has already locked down this hack?  That's pretty quick!

Things that might be worth trying:
-Using a completely valid old DS1102E style serial (think somebody posted one earlier)
-Trying to get hold of a brand-new DS1102E and see what serial they are using now (maybe they just changed the pattern the firmware checks for)

Glad I got my scope shipped from a vendor that had stock on hand.  I'd be careful of ordering from any supplier that might use "directly-from-factory" supply.

Not exactly.

Maybe this situation is not (yet) related to hack, maybe it is related only to product revision.
(also I do not believe that this hack is first known outside China. ;) 
 
..... but maybe they have not so open mouth...)

Laff, gotcha.  Makes sense that it would have been found earlier but kept closely guarded, since some Chinese middlemen have a talent for, shall we say "optimizing the value of goods before reselling them"  :)
Wonder where I could get a DS1102E label to make the front of my scope match it's capabilities....

Have you tried replacing the entire serial with a known-good, older-style DS1102E serial?

Simon:
I would think all known 1102 serials have been blocked in the new versions, it is obvious that rigol saw this thread and other mentions on the net pretty quickly, and I'm sure  blocking this hack was simple: just remove the model changing commands from the command set, clearly this was an easy way of choosing later what the scope would be, now they probably have to Flash two different versions of the firmware to the scopes to make the choice ie: it is preobably now hard coded. Perhaps copying the firmware of a 1102 to a 1052 would get around that but then they could put something in like the bios to prevent it being accepted. suerely at some point a new hack will be found but it wil be a case of how far one is willing to go to carry out the mod

Guess what the next blog is going to be about...

Nothing subtle about you, Dave.  :o  Are you planning on rubbing their nose in it, like you did with the "caught with their pants down" incident?  I'm sure that had them ROTF at Rigol HQ.

While you're at it, perhaps you should point out that this really turns the DS1052E into a 150 MHz scope.  If you look at the rise-time results posted by flolic and rf-loop, and sweep tests by Andreas (JimBeam), the performance of the modded units (as well as the stock DS1102E's) definitely meets 150 MHz spec criteria.  (down 3 dB at 160+ MHz, risetimes <2 nS)  Also, the gain flatness is good (i.e., uniform rolloff, with no peaks and valleys, -4.5 dB at 200 MHz).
