funkysy, sounds to me like you are doing all the right things. Clean your logic board using [guide|5825|this guide] for a general idea. It was written for a 3G but applies to your phone as well. After you got is cleaned, check for any missing, or charred components. Check your battery contacts with the phone plugged in and see what your voltage is on those. Also, consider changing the dock connector, it can cause errors like you are referring to.Error 1611 is well explained [http://support.apple.com/kb/TS3694|on here.] Hope this helps, good luck.
