Anyway, I was wondering if it might be possible to swap keys between 2 identical drives without the need of injecting ixtreme onto the new dvd drive. The point is that I need to fix and old drive by replacing with a new one. Console at this point is not modded. So I want to put the key from the old drive onto the new one but I don't really want the new drive to read backups.
Is there any way to accomplish this task by let's say....renaming the dumped key to cfw.bin?

Keep in mind that although swapping DVD PCB boards is an option, is not desireble due to extensive soldering (too much hassle)....thank you all !
