In order to test if its running ok, etc... --- End quote --- One day. --- Quote from: Trax on June 28, 2015, 05:48:39 am ---And what happens if the scope would fail and be in need of repair while having hacked options? I guess as long as it boots the options could be simply removed before sending it in, but what if the scope wouldn't boot at all? --- End quote --- I don't understand the question. What is the relation between entering a bunch of codes and a warranty claim? Maybe in the states this is illegal but where I come from it's completely fine. |

Would they repair it? Imho they would know that the scope was opened as to hack it a memory dump is needed. Or would they do something to disable the options permanently, setting/breaking some jumper, burning an eFuse or writing to some read only memory, etc... |
