My iphone was working fine until dropped it and it split open, i tried to plug all the things back in and restart but it wouldnt start . What should i do and what tools do i need ?

The photo looks a bit blurry but your top camera flex looks intact, however the LCD/Digitizer ribbons look torn, you will need a replacement LCD at the least for it Tools you will need are: a P2 pentalobe screwdriver for the bottom screws Y000 and a PH000 screwdriver for the rest of the screws for the screen/brackets

Go through this guide to make sure you have all the connectors in place correctly and that none are damaged. The photo you posted is just not clear enough or comprehensive enough to tell: iPhone 7 Plus Screen Replacement
