There's only four choices.  Try them all. 

It might be mentioned somewhere... Have you read the entire thread?  I know it's very long, but there's like ts of knowledge in it for someone willing to take the time.

Yep, been through it twice, and even downloaded this an other related threads and did a txt search but nothing that says what sort of format the file should be in or if the advanced tab is relevant.

Ok, so I tried unlocking my new MSO2072A (3.00 SP1, HV 2.2, SN DS2F1629*****) using the DS2000A Upgrade Utility, but that did not work, So now I guess I'm gonna have to use the JTAG memory dump method. I really didn't want to because I'm afraid of messing something up permanently, but I as far as I've seen there are currently no alternatives.
I've already read most of this HUGE thread, and I guess I can say I understand the basic logic of it all, but the specifics are a bit over my head.
 
So now I have to order a JTAG adapter (and wait weeks for it to arrive). Is there any difference which one I get? I'm not really looking for the cheapest one, but one that would make the process simpler and therefore reducing the chances of me bricking my beloved new scope.
