I just updated my OS to 5.0.0.900. The installation completed, but now the phone is stuck on the T-Mobile screen. I restarted in Safe Mode and that seems to work fine. I read something about Themes causing this issue, but I don't have any Themes on the device. Just using the default theme. I did the battery pull now at least 4 to 5 times. The only other apps I have are gmail 2.0.6, google maps 4.4.0 and google sync 0.7.3. I have a Blackberry 8900. Any help would be greatly appreciated.

thanks

Did it boot properly after the battery pull?

No it did not. It is just stuck on the carrier screen. I left it there for 30 minutes and still nothing.

Probably a corrupt file or something you run doesn't like the new OS.

Try wiping with Jl_cmdr and reloading the OS.
