Ok. So I sucessfully rooted my phone and I then attempted to flash a custom ROM following the instructions in this link How To: Load a Custom ROM on Your Android Phone (After Any One Click Root Methods) | TheUnlockr.
The problem is that I have the Droid (D1) and while the instructions worked the same as my phone I think that something is different. So my question is how do I "undo" this?
Thanks in advance for the help and sorry to be such a newb.
