Jailbroken 4.3.5 keeps rebooting. Help!

[m3funny]

I have a iphone4 4.3.5 jailbroken with redsn0w. The other day the phone just rebooted it self so it kept showing the apple sign over and over. I tried to tether boot it, but it makes it as far as the pineapple symbol. Once I get to the pineapple symbol it reboots itself again and shows the apple symbol. Anyone know what's wrong?

Restore and rejailbreak

Ok, I tried to restore it through itunes, but I'm getting a message "The iPhone "Iphone" could not be restored. An unknown error ocurred (1611)". Anyone know anything about this error?

1611 only occurs when you are trying to downgrade, you should just be doing a normal 4.3.5 restore, restoring in DFU mode helps.

Ok I tried to restore again. Now I'm getting error 2006.

Sounds like you have a bad USB cable, try finding a different one.
