Nokia Nseries :: Camera Not Work After Software Update?

I recently updated my n97 mini to latest update 30.00.004. after update lcd in split into half and the other half shows inverted display.the half screen that works keeps switching between portrait n landscape, diagonally.the second inverted half shows the last screen(as if from memory).recently i found that the camera is also not working.shows unexpected error occured. restart (something). () doesnot show up on screen.i went to nokia care. they said it is lcd problem after trying to reinstall update. i dont understand how can it be a lcd problem, when phone was perfectly ok before update. also lcd problem cannot connect with camera problem. i have previously installed updates n they installed perfectly. i have reinstalled the update repeatedly but no use. exactly same problem.
