Water Damage stuck on Connect to Itunes

Hi All,

My Iphone 4 is water damaged.

I did the following

1)Kept it in Rice for more than a week

Nothing happened the Phone did not turn on

2) Used 99% isopropyl Alchol and Cleaned the Logic board , all the Connections as far as I could

Now when I connect to the Power source

Connect to Itunes Logo comes up

If i remove the Power source the Phone turns off

if I try to restore it with Itunes i get 2001 error

Is the Logic board dead? what else I can do to restore the phone
