[never mind problem fixed!!]
I initially tried to flash the Lite'ning ROM but then I got the issue where there is a boot loop with the (S) screen. Afterwards I tried following the instructions on this thread: [READ THIS] Got a Boot Loop? Don't post a New Thread! - xda-developers
After this, my phone doesn't even go past the Samsung Galaxy S II screen (black and white) and just freezes there. The only way I can turn it off is to remove the battery pack. Fortunately I can still access recovery and download mode. I've tried redoing the instructions on the thread i mentioned several times and still no go. I have no idea what to do right now. Any suggestions would be greatly appreciated!!
