You should be able to pull the battery, connect to the USB, start Loader.exe and then plop the battery in once the install starts without wiping again.
I am on bb 9900 and I upgraded some software, one of it caused the App Error 200 Reset :-(
I searched, and found suggestions to reload blackberry device software (see below)
Funny thing is, when I selected "Update..." i don't get the dialog box with
"A dialog box appears and indicates that there are no BlackBerry Device Software updates available. Click View other versions in the lower left corner."
but get "You are currently receiving email notification ...."
BlackBerry Desktop Software 6.0 to 6.1
Connect the BlackBerry smartphone to the computer and launch the BlackBerry Desktop Software.
Click the Device menu and select Update...
A dialog box appears and indicates that there are no BlackBerry Device Software updates available. Click View other versions in the lower left corner.
The check box for the currently installed version is selected in the Available Versions list. Click the Install button.
Clear the check box next to Back up device data.
Click the Install update button.
