It's definitely worth doing, I have the same model, it's my go-to field scope. It just takes a little patience, and care with the warranty sticker.

My main negatives are the screen-only serial decodes, cluttered screen and slow UI, but for the money I'm certainly not going to complain, it gets the job done in a very compact and usable package

I have my memory dumps if they are of any use to anybody with the know-how to work toward updating rigup. There was a message somewhere earlier in this thread where somebody claimed to have gotten working licenses on 4.03.SP1 by dumping the memory while the Rigol logo was on-screen, so I took one then too.

I'm willing to do anything else that might be useful. I already have a DS1054Z fully unlocked, so I'm not in any huge rush (though I would like to sell the '54 once I get the MSO unlocked).

Are you sure the list of compatible JTAG adapters are in message #2413??? On page 97??? I found that message but it has no list of JTAG adapters. Anyway, I'm trying to find something cheaper than the Olimex LTD ARM-USB-OCD-H . This is quite expensive!

I was thinking about this one which is a lot cheaper:
http://dangerousprototypes.com/docs/Bus_Pirate_v3.6

Is this one suitable for this job?

Yes, I'm sure, it was the first message from buergi: "Reply #2413 on: 11-01-2014, 18:59:55"
There are also several other messages in this thread from various people with various jtag adapters. Just do a search inside this thread.
Or do it the other way around. You found a cheap adapter? Search the forum if someone used this model before.

Cheers
