So my phone was super laggy so i did a quick factory reset and restored my contacts etc, Then rooted it. Then i was reading around and found a guide on how to get to 2.2.1 so i thought what the hell i'll try it. So i download all the stuff do exactly what it says and ... it just keeps getting to the Samsung Galaxy S Vibrant I9000 Screen and goes black and then comes back to it again. I need the firmware for a Samsung Galaxy S Vibrant I9000M is what the box says so i can go back to default and upgrade back to 2.2 from kies. PLEASE HELP or i'm without a phone witch i need every day! Thanks in advanced!
