I have two 360's I want to update to the new 1.9 but I have a problem. I have only one dummy.bin and I'm not sure which box it goes to. Both have liteon drives but I want to verify the keys before I go any further. I figured the easiest way is to dump the keys again. I'm running 1.6 right now and jungle flasher reads the firmware as 7485. My problem is I'm confused about if I can still probe R707 with the tray open or do I go with the new tutorial and probe MPX01. I built a probe a long time ago for probing R707, if I need to probe MPX01 can I use the same probe?
