Hmmm. All I can say is atrix was a bad choice, sorry, 'Mr obvious' I know. You should have tried D3 if you wanted to test the waters. It seems to be a similar build to the bionic having the same exploit for root and all.
Unfortunately, there are a lot of brave souls that are guinipigs, as there are for EVERY new phone. You might just have to hold off for a bit. I'm sure its fixable though. Usually, you are not permabricked unless you deleted files w/o a nandroid back up or flashed a rom wrong.
As far as snarky's comment, pay no attention to this guy. He just gives people **** in the root forum and offers no advice, blaming rooters for high phone prices and calls them fraudulent, morons, etc.
