Hello, I'm brand new to the world of Blackberry, loving it until now!
Bought it unlocked from eBay (originally AT&T branded), was working great, then I (stupidly?) tried to update the OS on the phone via Desktop Manager to 4.5.0 something (the latest). Now it starts up, red light blinks, hourglass appears for about 3-4 seconds, then screen goes blank, repeat to infinity.
I removed the micro SD card, same problem. I remove the SIM, and the phone boots just fine. Tried a wipe from the Security menu, same problem with the SIM installed. Tried downgrading to the earlier 4.5.0.xx release from DTM, same problem.
The weird thing is, if I put in my other SIM from the same carrier, the phone works fine. The "problem" SIM in the blackberry, also works fine in two other non-RIM phones!! The only difference between the two SIMs as far as I know, is the not-working one has a different service plan, and is pretty full of contacts and SMS junk.
I'm not quite sure what the "BlackBerry Operating System Downloads" page means (new to this..) Should I be using the AT&T image instead of whatever the Desktop Manager wants to install?
Any & all suggestions appreciated greatly.
Thanks,
Skye
