Hi. I want to downgrade the software on my Nokia MM 9802S. After ALOT of searching i've finally found some firmware and utility to do so at this site:
http://www.gr-digital.gr/recfiles.htm

Has anyone tried these firmwares?

My real question is: In the guide it says that I need a null modem cable. All I have is a serial cable i received with my programmer. Can I use this one? I actually don't now the difference and google hasn't helped me that much.

Thank you for your patience.
