so heres the issues. i bought a 1st gen iphone from a private seller..and i was trying to use pwnage tool to unlock it and whatever..but theres an error 6. so i tried to enter DFU mode the problem is that i can't even turn off the iphone..so i tried to use ziphone to enter dfu mode but that doesn't work either..and now all the iphone does it turns off and on by itself like every 10 second..i can't turn it off manually. when its on, it has the usb connect to itunes picture and just turns off after 10 second and reboots back to the same screen. someone help.

use ibricker to get it into dfu or restore mode

man ive tried everything..can someone please help me get this fix..it just keep on turnin off and on by itself and goes straight to the connect usb to itunes...ziphone would not detect the phone..f*cK!.help

mine did this before...
i had ibricker and itunes running and i held the power button and home button until i got the USB cable thingy on phone... once itunes recognized the phone i quickly used ibricker to get phone into dfu mode
