The title pretty much sums up my problem.

I used the instructions from here to re-flash my N900:

And now as the N900 starts (takes a really long time) it does not ask for the SIM-card PIN code and as it is started it just shows a SIM-card icon with a red line over it near the battery icon.

SIM-card is fine as it works on my N95.

Any ideas what's wrong?

UPDATE: Tried another SIM-card. Nothing. Also PC-Suite is not recognizing the phone either. I even tried flashing the eMMC but it didn't make any difference. The small lights in the bottom of the screen just blink for about 45 seconds and then after the boot video the phone start as if no SIM-card is there.
