Hey guys! I’m new here. I have a water damaged Iphone 7 Plus and it has broken logic board (at least what repair services say), and it cost 400-500€ to replace to a new one, and im not willing to pay that money, because i could just buy a new, undamaged one. So i would like to know is it possible to replace all parts from my old and broken logic board to a new one? And maybe is there any tutorials or something? Thanks for any help!

it would be easier to send the board to someone that specializes in liquid damage and microsoldering. its maybe just the kind of repairs the shop you took it to doesnt do

Well, considering youd need an expert microsoldering tech to repair it (trust me you cant do it yourself on this one) and that moving ALL components from your board to a new board would probably take 100+ hours of labor under a microscope. It’s not worth it man sorry.
