hey everyone I'm Kelsey with iFixit and
today I'm gonna show you how to replace
the i/o daughterboard
on your samsung galaxy s 9 plus for this
repair you're going to need an eye
opener a suction handle I fix it opening
pics a spudger a phillips double zero
screwdriver a sim eject tool and
tweezers
we also recommend using a magnetic map
for this repair it'll keep your screws
organized and safe from rolling away
start by making sure that your phone is
off and use your eye opener to heat up
the back panel to soften the adhesive
and repeat if necessary if the adhesive
continues to give you a hard time try
using a heat gun or a hairdryer lay your
suction cup on the phone as close to the
heated edge as possible then use your
pick to cut away the adhesive all around
the edges once you have a portion of the
panel separated insert a pic to keep the
adhesive from resealing work your pick
around the phone cutting all the
adhesive but be careful don't slide the
pic in too far or else you might damage
the fingerprint sensor once you have all
the adhesive cut lift the panel and
disconnect the fingerprint sensor on the
mid frame you have 16 Phillips double-0
screws that hold the NFC antenna
wireless charging coil and the speaker

once you've removed the screws and
components go ahead and disconnect the
battery grab your sim eject tool and
remove the SIM card from the slot to get
the motherboard out you'll need to
disconnect six cables and remove one
screw
just like that you can remove the
motherboard going down towards the
charging port remove one screw and
disconnect the cable holding the
headphone jack in place use a pair of
tweezers to lift it out remove the
daughter board by unscrewing four
Phillips screws use some tweezers to D
route the antenna cables

and then use a spudger to release the
port from the phone start by loosening
it on the side where the motherboard was
and work your way towards the charging
port once loose it should come right out
