I'm afraid I may be bricked but just wanted your and everyone's opinion before I give up. I only found your post after I (backed-up and) uninstalled the "blur.services blur.res 2.1-update1" on my att handset and now I receive a continual force close error saying that "The process com.motorola.blur.service.main has stopped unexpectedly. Please try again."
After this initially happened I try to re-install my back-up with the Root Uninstaller but got the att 'we can only install from trusted sources error' or no message at all when trying the install "as a system file" option. I also tried the Sideload Wonder Machine and only got failed errors.
Then even after a factory reset the error still comes up and in fact I appear to be stuck at the initial motoblur starter screen set up being unable to either log in nor register a new profile (the logging in or confirm new ID waiting bar gets close to the end and then just never completes).
Finally, because I'm stuck in this motoblur set up screen I'm unable to enable debugging mode and use adb. Does anyone know how enable debugging mode via command prompt or how to fix this otherwise?
UPDATE: After being stuck for a while at the Motoblur set up screen without the the ability to set debugging and thus somehow use adb, I found I could still update my device software through Motorola's website. After the update, my device started up without the force close error. Here's the Motorola website link:

There were some new bloatware programs added btw.
Fyi, after rooting again (z4 root did not work for me either; neither temporary root or permanent root, it only timed out basically) with SuperOneClick (link below), backed-up with Titanium Backup and froze the above list of bloatware with Root Uninstaller and for some reason my internet connection and android market connection stopped working. I unfroze with Titantium Backup and then the connections were restored.
