Odd, I had one that the fellow said was done with 2.0 and when I read it with 16, it read it fine, I did the hex edit and programmed the ham stuff we use on 900 but it had 2.09 firmware on it. I guess that was the reason I asked about firmware. I'll assume you actually tried to read it with 16 and it didn't work.
SO, on to 2.0... Yes and I don't have it in front of me, there's one specific version of 2.0 (or so I'm told) that you can swap a .dll file out and it will read and write to the XPR series (and SL's if not the e series) . I can only tell you it has worked for several of us here in my area. We don't do up to 941 but, do the ham stuff. when I get my programming laptop back, I'll see if it works up to 941 and report back. (may be a few days I loaned it out to a fellow ham to do some stuff in his area). To my knowledge however no one has got it to work yet on a 7550e, for some reason those won't take but we have done it on 4- 5580e, and they took the ham stuff just fine. I have no experience on getting them up on 941 but like I said I'll try that when I get it back.
