Hi,
Whenever I try to upgrade to the latest version, my n900 will get stuck on the flashing dots stage before the handshake animation. However if I flash it to an older version it'll boot, but it says there is no simcard inserted which I've been told will be fixed if I get onto the latest firmware. Flashing or installing over the air makes no difference. I left it at the flashing dots for around 4 hours and it still didn't start. Any ideas besides reflashing as this obviously isn't working
