I bought a nearly not used BB 8820 in mint condition some time ago, and since I use a Mac, I don't get to update the device.
I had the software version 4.22, but wanted to upgrade to 4.5. So I connected it to Windows, trough vmware fusion on my Mac, and updated to 4.5.
After the 4.5 update, the BB won't read my sim card! I tried various things, as downgrading as far as I could (to an earlier version of 4.5), but that didn't work out. I could only get the SOS signal, and the phone does NOT ask for PIN code. I have tried various sim cards, also from different carriers than mine.
I was scared that it might had become locked, but when I went to Settings, and then Sim Card, typed MEPD, everything was "Deactivated". So it's not locked, right?
I'm living in Norway, and using an Norwegian carrier.
Hope you guys can help me out!
