Iphone 4s rear camera not working after teardown

Hi!
I've a Iphone 4s that the rear camera wont open the shutter after replacing the screen.
Also the flash doesnt work either (have tried with the torch app), I've tried to replace it with another one but that didnt solve it.
The front camera works.


I've read this Guide: http://www.ifixit.com/Wiki/iPhone_Tr...ting_Guide_101

But it applies to Iphone 4 and the logicboards aint the same.

I've also tried to reset it etc, no luck.

So is there anybody who is sitting on a solution for this?
