Really need some help bad

[Milla000]

hey, i'm in a mess here guys... basically I had an iphone 3gs and the screen was smashed everything worked perfect apart from the screen was smashed. I gave it someone to fix and they fixed the screen and added a new digitzer, when I received the phone back some of the touch wasn't working so I gave it the person back and they replaced the digtizer however when they did this the iphone now gets stuck on the apple screen and after a while it will turn to a spinning thing then back to the apple or it may flash and go back to the apple, any ideas? I have tried a restore and I am getting fed up now...i'll try anything to fix it?

Did you put the device into DFU mode when restoring or did you just plug it in and click Restore.
