I rooted this phone (not even mine it's verizon's phone) and everything was working flawlessly besides a couple force closed apps because it's slow. I wanted to change my stock font so I downloaded an app changed it and it had to reboot because of changes. Well it rebooted and got stuck in a boot loop. I got to my operating system recovery but I need an update.zip file. I got a couple different files from forums but none of them seem to work I keep getting signature errors and other stupid errors. This is day 3 of my boot loop and I'm getting really stressed about this!
