I have a Sprint 9630.
I got a 552 error--I tried resetting using the instructions on BB's website. I pulled the battery, connected to the computer. My PC "beeped" like it was connected. I saw my pin briefly in the BB Desktop Manager. I went ahead to application loader-->update software like it said. My computer started beeping a few times like I was unplugging the BB and plugging it back in, and the pin disappeared on the Desktop Manager.
Now I can't get the Tour to boot at all. Previously it would try and load but give me the 552 error. Now it won't turn on at all with the battery in--the LED light just keeps flashing red (two quick flashes).
If I plug into the computer it still beeps like it knows a USB device has been plugged in, but that's it.
What do I do?
