Okay, i've tried google and everything, i restored my iphone 4 with a custom firmware i made using sn0wbreeze and made a 4.3.2 firmware. I had cydia installed and everything on it working fine for like 10 minutes, then i turned it off and it immedently went into DFU mode, i don't understand why, but it does that everytime i reboot it. So, i boot it tethered with redsn0w rc16, and it works for a little while, Then it the screen just stopped showing up, it shows up in itunes just fine, but the screen doesn't show up. I don't know why, i've restored it time and time again before coming on here, please help me.
