I have a very serious problem.
I am currently using a 8320 on Tmobile
I was trying to install the new 4.5 OS.
During the middle of the installation process, the USB cord was pulled from the computer.... long story.

my device now only has a white screen with a black bar on the top. An hour glass appears when it is restarted. I plugged it into the computer again to do a restore but my Desktop Manager will not see the plugged in device. My device manager however does see the device. Anyone know how I can restore my BB? TY for your help in advance.

I mobile so I can't paste but check the faqs section and look for how to upgrade your decice software in there.

upgrading is not really it, it seems as though i have no software on my actual device. I have the restore file on my computer, i just cannot get my desktop manager to recognize my connected blackberry.

See if this works...

taken care of. 2 hrs on the phone with T-Mo RIM help and finally done I believe. had to completely wipe the sysyem and reinstall. Apparently, if the Desktop Manager says it cant see the device it still can, its up to the Device Manager to see the PIN. oh well, hope it works!

Yes, all of that could have been found in the FAQs.. And saved you a few hours.
