iPhone Constant Error 1602 when trying to restore Jailbroken phone

[Spoontaster]

So I bought an iPhone 4 off eBay which was jailbroken (on OS 5.0.1 I think). I went to restore the phone and it came up with Error 1602.

I've tried every solution to fix this issue including putting it into DFU mode, using iReb, using a different computer/USB cable.

Other things to note: only when the phone is plugged directly into the wall will it function "almost" normal. When unplugged from the wall, either just the phone or connected to the computer, it shows nothing. Won't turn on or do anything. The computer only recognizes it in DFU mode.

I've filed a claim through PayPal (still ongoing) but the guy I bought it from said I ruined the phone by trying to restore it.

Can anyone help me? I don't want to be out $250 :-(

Sounds like bad battery

Hm, I don't think it's a battery problem as the issue only started after I tried restoring it.

If you have SHSH files saved for 5.x.x then restore it to stock, then test it.

Unfortunately, as I bought this phone I didn't save the SHSH and just learned about it recently.

And the phone won't connect to try and save the SHSH.
