I cant get my phone into DFU mode. I had tryed to downgrade from 1.1.1 to 1.0.2 after if was showing repair needed. After the downgrade in can up with an error 1604. I tryed iBricker but the screen stayed green, so i downgraded it again.
Now the phone appears to have turned itself off, and can not turn it on, or put it into DFU recovery mode.

Any advice please???
