I've bought a 2nd hand w910i from eBay to take travelling so the practical need for a solution here has gone

However, having spent so much time fussing with it I'd still like to see if I can resolve it, even if attempts end up ruining the phone for good. It's 4 years old and has a faulty keypad so it's probably worthless anyway.

I would require a bit of handholding as I'm not a hacker/code writer/unlocker so appreciate your patience.

BTW the sound quality on the w910i Walkman is I feel like I've got a brand new pair of ears!
