don't like to admit this but I am one of
those people that have dropped their
phone in the toilet and sometimes when
you get that kind of water damage you
might have to replace your logic board
so today I'm gonna show you how to
replace the logic board in the iPhone 7

for this repair you're going to need a
pee tube pentalobe screwdriver an eye
opener a suction cup a spudger some
iFixit opening pics a tri point wide

from other users who have already

DIY fix keep in mind that opening the
iPhones display will compromise as

to avoid exposing your iPhone to liquid
damage in the future as with any repair
be sure your phone is powered off before
beginning then begin by removing the two
pentalobe screws on the bottom edge of

screen in place detailed instructions on

to the lower half of the display
assembly just above the home button be

the home button as this will prevent a
seal from forming between the suction
