I got a brand new unmodified DS2202_A_. So I would like to help to enhance the situation... :-DD
I don't have mature experience in hacking this sort of stuff. How can I help you guys? Are there any pointers how to create a memory dump from this beast? Where to send the dump? :-//
Please don't hesitate do contact me with your requests... :-+

I too now have a DS2202_A Rigol Oscilloscope. I purchased this online, was meant to be a DS2202, but I was upgraded to this unit as delivery was taking too long. I suspect this one simply supersedes the DS2202, as it is exactly the same, but includes a 50 Ohm impedance option, and CAN bus decoding! This really tips the scale for me on an already very fine piece of test gear. Being a hobbyist, I could not afford the typically more expensive 'scopes that we use at work (Tektronix) and I am very pleased with this purchase. A very well made scope, along with all the bells and whistles. But enough about that, I have tried to some of the solutions here (IE install NI runtime and DS tools etc) to try and get the options installed but they don't work (doesn't surprise me, the guys here appear to have done such a good job at getting past such measures, some changes by Rigol were inevitable).
Being such a new scope, nobody has probably had the time/opportunity to take a look under the firmware hood of this scope. Has anybody had any success with the option keys on this scope yet? I might have missed something on the forum. If not, can I help in some way? I know you were asking for a .GEL file for the firmware, but I was unsuccessful in locating firmware upgrades on Rigol's scopes. Perhaps I have to work through the dealer. Anyway, assistance is appreciated, I would love to have all the features (especially trigger features) enabled, as they can be extremely useful at times, but my budget is already blown and there is no way I can go parting with hundreds of dollars for these options.

No, as mentioned earlier the private key seems to have been changed for DS2000A, so none of the DS2000 keys works for DS2000A.

As mentioned earlier, do a JTAG memory dump.

As mentioned earlier, there doesn't seem to be any firmware updates available for DS2000A yet, but of course it doesn't hurt to ask again, maybe a new one has come out now.

Can someone give me step by step instructions for upgrading the firmware on a DS2072?
I am expecting the CH1 light on while upgrading and then all lights on when complete. My DS2072 goes immediately to all lights on with no upgrade.

Bottom of this post.

Thanks Marmad but that is what I have been doing and it doesn't load. I'll keep researching maybe someone else is having this problem.
