Try using redsn0w and select boot tethered when you restore with custom firmware it sometimes gets a tethered jailbreak instead untethered.
So in other words its probably not in DFU loop, just needs booting tethered.
no, sorry. I had tried this before, and I've just tried it again. the 'booting tethered' option in redsn0w does absolutely nothing. no screen flickers, anything. I'm starting to loose hope.
this is not (or it is very unlikley) a harware malfunction as the phone was working, jailbroken at one point, and its a brand new iphone 4.
i may have forgotten to mention this part: after restoring with the custom firmware for the first time, i was able to boot the phone with redsn0w. i went on cydia and installed untrasn0w, witch required a reboot. upon rebooting the iphone, i was presented with this problem. sorry for this lack of information.
