At Tastenpoint you will not receive any support,
I have already tried with my Groove XR.
You can try to contact Domenico, he built Lionstracs.
You have to find someone who has a Groove X6 and give you a copy.
The basic structure you can restore with the OS51, but you still need the sound files (gigalibrary), the preset folder and the .Wine
If the X6 already has a PI code, then this will not work.
Best would be if you would try to restore an older partition of your HD.
Is not easy but could work.
Then you have everything that was once again on it.
