i jail broke my iPhone with blackra1n last year but one morning i woke up and it was on the connect to iTunes screen. My brother ran blackra1n on it and it started back working but a week later the same thing happened i woke up and it was on the connect to iTunes screen but when i use blackra1n it runs and then the screen goes black so i press the power button and it goes to the connect to iTunes screen again.When i connect it to iTunes its says that its in recovery mode and disconnects by itself sometimes.How do i fix this?
