I don’t know what has to be done to crack it all the way but I know it can be done. I just tried to figure out how to do it for fun but that’s as far as I could get with only a YouTube education. You do not need to connect to a controller to see if you got it. Just open it up and see if you have a Service menu. Unless you are working on the newest tablet version of IMS, it’s quite a bit different and you would be looking for an Adjustments menu instead of Service.
