hello i just recently got my prevail and rooted it the other day all was fine, and then i decided to go to a custom rom with all these cool ics features and such, worked out fine at the beginning and then it started to glitch, so i decided to go back to stock rooted, and used odin and all the correct files as downloaded from the forums and then now i am stuck on a samsung screen it wont go past it at all, i try to do cwm recovery and nothing just the samsung screen, so then i try to go to downloading mode and nothing but a black screen, right now i am at a loss on what to do, what do you guys suggest for me to do to get my phone back up and running?
