Well, i had fission ROM. It started messing up and having errors. So i decided to go back to my stock rom. I didnt create a backup (stupid i know) so i got a .sbf. I installed 2.4.33. I got a boot loop. So i tried 2.4.29. Same thing i got a boot loop. My sister and i got our phones the same day. Same phones. I got her's and went to settings, about phone, and saw that it says Android 2.2 so does this mean i need an sbf 2.2? If so where can i find it? Or if not how do i know what sbf i need?
