3GS 2001 Error help please

Hi All

I've been given an old apparently broken 3GS which I'm told was jailbroken and then they tried to restore it and it stopped working. They've no idea how it was jailbroken or what with so I'm in the dark there and I'm also quite new to the procedures required to jailbrake these so please bare with me.

The phone as it stands now doesn't switch on using the power button on its own. However it does switch on using power + home and releasing power after 10 seconds then home after another 10 which brings up the plug into itunes icon for restore mode. When I plug it into itunes to restore it goes through the verify with apple part, prepares to restore, the phone goes to reboot and doesn't come back on, causing a 2001 error.

I can also get the phone to start up in DFU mode with a black screen, again when plugged into itunes to restore it goes through the verify part, the phone goes to reboot and doesn't come back on, again causing the 2001 error.

Also another thing that might be worth mentioning is that the phone will only turn on in DFU mode or restore mode when plugged into a mac or power, all other times it just appears dead and won't switch on.

I've read through quite a few posts on here regarding this error, stopping itunes helper etc, but nothing seems to work.

I'm getting the feeling it may be a hardware problem with the phone not being able to switch on without power connected.

Can anyone please shed some light on this, or have they experienced something similar and managed to get round it?

Seems a shame to bin it as it's a 32GB version.

Many Thank in advance for your help.
