First, I wanna say big thanks to all of you guys and especially to Safar for all of your help!
I've succesfully liberated pair of DSO-X 2012A and MSO-X 4034A respectively, and they works just fine.
As PhillyFlyers stated two posts earlier, 4k series can be succesfully hacked with the .bin.comp file that he generously provided. As .lnk file, I simply used that one for 3k series and it suites just well, thanks again to Safar. The license list is enormous, as you can see.
Sorry for my english though.
