IPhone :: Error - Itunes Was Not Able To Establish Connection To This Iphone, Caused By Unknown Error 0xE8000001

after dropping my Iphone 4 on the floor it can't connect to my PC, the error i am getting in Itunes is "Itunes was not able to establish connection to this iphone, caused by unknown error 0xE8000001". Itunes suggest to go into an applestore and get it solved but since third party has replaced the screen will apple not touch it....I have tred to uninstall itunes after closing down a few apple files via "task manager" and hard restored the Iphone but the phone will not acctivate, only get to the screen saying "connect to itunes". when i plug in a fully functional USB cable in a fully functional USB plug in my PC (windows 7, 64bit) does the phone connect and disconnect with the PC a few times, sometimes it keep on connecting/disconnecting but when the phone able to establish connection do i get a box saying "error 0xE8000001" and when clicking on the phone can i see its charging the battery but no possibilities to make a firmware restore or anything els. (have only the option to "eject" the iphone). is it possible to go one more step back than "hard restore" so the phone need to reinstall all hardware ect ect?

Info:
iPhone 4, Windows7, 64bit
