Stuck in DFU Mode Error 4014! - Itunes Detects recovery mode.

I have looked everywhere for an answer on this and have had no results.

I replaced the screen in the IPhone 4s yesterday, After about 10minutes being plugged into itunes.The display went off and when I tried to turn it back on ITunes flagged it in DFU.

I replaced the screen with full esd earthing so I know I haven't static shocked the board.

I have sinsce tested the screen in another IPHONE 4s and the screen is working correctly, So I know the screen has not damaged the board.

However this has been previously repaired via another team so who knows.

I have no display or life from the phone.

Things I Have tried.

Restore/Update + IPSW Recovery on Laptop Win8

Restore/UPdate + IPSW Recovery on Pc Windows 7

Apple store( Premium resller ) Restore MAC .

These all resorted in error 4014.

I have tired several differnt cables.

I have tired a new Dock connecter cable.

I have tried 3 different batteries.

TinyUmbrella Will not Detect as itis DFU.

RedSn0W will not work correctly as in DFU.

ReiB00t also will not detect.

ITunes Re-installed.

Host file altered in windows.

Anti - Virus disabled etcetc.

Iphone was getting extremely hot during the recoverys.

Even though everywhere says this fault is a connection issue. Am I right in thinking this is probably a logic fault and is not fixable.

The last thing I am trying now is fully charging the battery in another Iphone 4s ( So I can monitor the charge ) Then I'll put it back into the " Dead " iphone and try and recover.

HELP!

I'm just wondering, I realize this sounds dumb. But, since you're already out of luck, why not try putting it into dfu mode? Yes I know it says it's in dfu. But, just give it a try

im an electronics tech and fix many iphones, i had the same problem yesterday and the fault was the IC Backlight chip. when that is damaged your phone will only be detected (on computer) in DFU mode and when itunes try to restore the phone it fails because it cannot complete a test with the phone and sees the fault.

once you have exhausted all other methods of fix then test the ic backlight chip

Remove nand and reprogram if that don't work, it's probably an issue with ramm, which can be fixed by rebelling.
