people contributed to this thread probably now doing other things and forgotten the steps to do the upgrade esp your special D version that they never done/own, so keep asking this and that... do you think can help? or do you expect other people to reread the whole thread for you again? and presents your solution in silver platter?
And if you care to read the thread, iirc there is fw version that you need to downgrade to in order to do usb mod, edit and patch the header to fool the dso etc (google in the net how) , you should read that i wont bother to look again what page for you... and who knows whats your dso's fw revision anyway?
as for me recently, my ds1052e cal data is damaged (or went offed values) and i have to buy tl866ii xgecu flash programmer to read the whole content. Problem not solved yet because i dont know how to calc or repair cal data offset.. only drieg knows how to do that and he is MIA.. and any imaginations/solutions i've made not giving any good result. I think tl866ii programmer will be a nice buy if you want the unlimited access to your dso mod, save cal data before doing risky mod etc..
