I have a Samsung Galaxy S3 T999 and I rooted my phone last night. I was messing around with downloading Roms (foolish of me) when my phone turned off, I charged it and turned it on, but it was stuck and wouldn't get past the Samsung Galaxy S3 part. I can still get into Odin mode and I was wondering is there anyway I can bring my phone back to the stock version, if that would help turn it on. Or what could I do? Any help is greatly appreciated. Thank you.
