I wanted to thank all the contributors for all the various unlocking instructions, especially VT100 whose instructions I was following per post #39 for the keys to my options upgrade. It's nice to have a fully upgraded scope, at just the right price.
However, I have a question that I hope someone can clear up:
I first updated the bandwidth via the rooted OS & bandwidth.txt -> bandwidth.bak method, as that felt the most comfortable to me at the time. With that success, I started to feel more confident (or cocky, I suppose, lol) and thought I would then use the mem dump method to find the keys for the options, which I then also successfully updated.
So, this means that I did not use the "keys" method to update the bandwidth. Also, the bandwidth keys in my mem dump did not show a "duplicate" key indicating that the 200M license was active, but there is a "200M" reference nearby, and the PRBD? command shows "200M".
In addition, in my mem dump, there were only four 16 char bandwidth-license strings, and not five as VT100 suggested would be there, (i.e. indicating that one of them should be duplicated to represent the license key that the scope was operating under.) (Image attached)
I'm tempted to run the MCBD <license key> key command for what appears to be the 200M key (the second one, I presume, per VT100), as a belt-and-suspenders insurance that a future update won't clobber the "bandwidth.txt -> bandwidth.bak method" of bandwidth upgrade and return my scope back to 100M.
I guess I'm asking if anyone has an understanding or feel for the difference between a 200M license key install vs simply removing/renaming the bandwidth file? If I execute MCBD on what I've labelled the "200M key", will that duplicate the key (when I dump it again?) as VT100 suggests it should be?
I'm a bit confused that neither the 100M or the 200M key is showing as a duplicate, as I would have thought that, if VT100 is correct, at least one of them would be authorizing at least one bandwidth option.
I've attached a shot of the relevant part of the mem dump for the bandwidth keys.
Thanks again!
