Alright, I know what I have done to my Captivate, I just don't know how to undo it successfully. I rooted my phone with the old method (not the one-click method) and then proceeded to download Root Explorer so I could download 3rd party apps. I then flashed my rom to the Vibrant Hybrid ROM, but I didn't backup my stock rom (FML). Is there anyway to go back to my stock rom at this point? I am running on a MacBook and have not been able to find any info on this. Any help would be appreciated!!!
