Nokia 6100 "Contact Service" - need a fool-proofed manual
 

Hey guys,

I've already searched my *** off but I couldn't find a propper answer yet. My Phone Nokia 6100 shows "Contact Service", although I havent flashed it or messed up with the sotware some other way. Alright. I've found answers about what can be done. What I need is but a fool-proofed manual. What software do I need exactly to erase / flash the phone? Where do I get it? What am I supposed to do with it - step by step?
See, I've only little clue about all that stuff. Sorry that I bother you with my newbie-request. I just hope, perhaps one can help me out here.

Thanks in advance!

Happy-Phantom

Connected to the power supply it shows "contact service" as well as in battery mode. If that is what you mean.
