I tried to HW 4.6 to 3.9 got stuck restored to 1.0.2.
Now i can;t jailbreak it with ibrickr or anything else. Ibrickr starts showing a matrix like number effect and goes into endless reboot.
I have tried to restore with DFU to all the available firmwarre, i tried even restoring to 1.1.3 still no imei no wifi no firmware!!
Don't delete this post lots of ppl have this problem.
