I can not get out of recovery mode, iTunes Error 46?

Hey everybody,

I have following situation: After changing my battery my iPhone does not work anymore and iTunes tells me Error of no 46. My phone stucks in recovery mode and does not do anything.

Apple says it is a hardware problem but any ideas how I can fix it? Should I open the iphone and get off the battery and try it again ? Maybe the guy messed it up after changing the battery?

Thanks for your answers

Best.
