Yes, if I press U and connect it via the USB the Nokia logo (on a dimmed out screen) and the USB icon appear.

I'll try flashing it then. On the link to the bin files, which isn't working right now, but from what I can remember last night, there was no 44.1 download, just an older one and the new 51.1. Someone said 44.1 was needed before going to 51.1, which one shall I try?

Know anywhere else I can get the bin files from?
