Nokia N900 Sim Card not recognized

Hi, here is my problem. I turned off my phone before charging from my notebook yesterday, and my phone would not recognize my sim card after I turned it on (it has the sim card icon with a red slash accross next to the battery icon) . But it was fine before the it was charged, and I found out my phone took longer time to start up than usual after the problem. I did try my sim card on my N96 and it worked fine. So I am assume the problem is from my N900.


I did little research about people having similar issue as me, and this is what I got.

"use flasher to flash the EMMC image to your phone... then use flasher to flash the mideast/northafrica os image toy your phone.... in that order, the order is important"

I found that from Nokia Europe forum


So I flashed the EMMC, this part worked fine. But I had problem when I tried to flash the OS. Picture "flash01" is what I got during my flash. "Flash00" is how it should done. Mine did not finish completely, and my phone didn't reboot as it should.


This is about it. I have no idea which part went wrong, or it is not how I can fix my problem.

Please help me with this.


I am using Vista 32-bit, and the firmware I tried to flash is
