I recently inherited my older brother's phone. Like the fool he is, he tried putting on a custom ROM a week before I got it. It went fine, but the THE DAY HE GAVE IT TO ME, he screwed something up. I have no idea what he did. I can't use the phone at all, it just flashes the logo "b ROM 1.3". Heck, I can't even turn the thing off. So my question is: is there any way to reverse this? I don't know much about phones, but I'll try whatever you can throw at me.
