Failed digitizer repair, diagnostic please!

OK major screw up... So I'm used to repairing phones and I've taken on this iPhone 6s which had a smashed screen, I thought no issue. During disassembly I stupidly slipped and put a hole into the battery fml. I replaced it hoping nothing is messed up but the device was of with no battery acid leaking, just the smell and battery heat. I replaced the digitizer and powered on, the screen doesn't display the apple logo but goes to home screen, works until touchscreen is used and then goes black, still on and all buttons work etc, I hope dodgy digitizer so I replace it, same issue. Then I notice I might have misplaced a few screws in the wrong holes, yeah not my day. Every once in a while the phone will fully operate for 1 min or so then randomly go black, sometimes when pressure is applied but it's not regular. What might be the issue and fix or is it just beyond repair? Thank you

Answer this question I have this problem too

Is this a good question?

They dont have acid in them, they are lithium polymer batteries. Where are you applying pressure to for making it work again ?. Does the original screen still work on the phone ? .

"Then I notice I might have misplaced a few screws in the wrong holes, yeah not my day." This part is the problem, if you screw the long screws instead of the small ones you get Long screw damage - the iPhone motherboard is structured in layers, when you put a long screw in you go trough the layers and you make a short.
