I've been experiencing some pad issues

However, the following pads are dysfunctional on my R3 at the moment:
LATCH
Pad 4 (SWAP TIMBRE)
Pad 8 (PROTECT)
I'm sure you can see my problem before I have to spell it out, but in case you're skimming this post:
I can't very well reset my R3 to factory settings with write protection enabled, yet I have no way to turn it off using the normal method (SHIFT+Pad 8 ).
Does anyone have any ideas? Is there another way to either disable write protection or even restore factory settings without disabling write protection?
Thank you for your time.
