Im having problems with my 3gs. When i got it back after it being re-jailbroken, i first had a signal problem where when i entered an app that uses the internet, it dropes the signal. then it started turning off randomly and the battery dies twice as fast as before. I have looked it up and people are saying that its the baseband because im running the ipad 06.15.00 and it can be solved by downgrading to 05.13.04. I have tried this tutorial twice with no look as it says error at the end:
Can i have some help please?
