Invalid sim/sim failure with 02.28.00 and 2.2.1 (5H11)
Hello.
I've been forced to use my backup shitty nokia as my phone since 2.2.1 first came out since I clumsily updated and thus upgrading my baseband. Now I found out that I was one of the lucky ones with bootloader 5.8 and managed to downgrade my baseband back to 02.28.00.
However I can't get yellowsn0w to work. I've just installed yellowsn0w from Cydia after downgrading my baseband while in fw 2.2.1. And now I keep getting sim failure and invalid sim errors when I enter my sim. Any ideas? It's a Norwegian carrier called Netcom and I doubt the sim is the problem.
Do I have to do a fresh yellowsn0w install to get it to work? My baseband is 02.28.00 so there should be no problem there.
