hello guys it's lan from sydney cbd
repair center and today we have another
screen replacement for
another huawei device the huawei mate
30.
so a client went into the shop and
wanted to have a screen replacement for
their broken
huawei mate 30 the screen has cracks on
it that we can see
through the camera but there's some
cracks there that
distorts the color and the operation of
the device
so it needs to be replaced so other than
that
the phone looks spotless almost brand
new so we're gonna be
take our time removing the back glass
here as the first procedure
so as with other huawei models this one
is held on by adhesives and the back
glass so we have to be very careful
there's also
some flat cables attached to the back
glass
and you can see here there's a qi
charger and
a big battery in the middle of it and
there's a the motherboard on top of it
like the
mate 20 that we repaired last last time
and
the camera system is front and center
at the back so we have to take our time
so other than the screen
all these parts will go back to the
device
we're not going to change anything but
the screen so we have a replacement
screen
here it is still
in plastic so we have to test it first
so we won't
waste any more time disassembling the
device to see
if it turns on so as we can see
the device is really drained no power at
all
so we can see that the charging
indicator on the screen
is showing up so that's a good
sign and it even boots up after
a few minutes of charging so the battery
is completely dead
zero percent so we're not gonna force
that for now we're gonna
continue with our disassembly process
and we can see here the mate 20 and the
mate 30
are quite the same in terms of its
general layout
we have the antenna cables on
the right side here you can see that and
there's some flat cables running across
over the battery to connect the
motherboard on top to the daughter board
below
so we're gonna remove the camera systems
you have to be very careful with that
and we're gonna remove the battery and
the
motherboard so we need to remove the
battery because the
flex cable for the screen
is underneath it so unlike the mate 20
we have to remove it
for the mate 30. so we can see that
the chassis or the housing is made up of
milled aluminum
so
just like that after completely
disassembling the device the
screen comes out it's connected with the
adhesives the same with the back
glass so we're gonna clean off these all
the adhesives so we can
put some fresh ones it is important
because there's no screws attaching the
glass
to the housing
so right here we're gonna install it
since there's no deformity on the
chassis we can just
line it up and press on the glass
no problem there and back to the reverse
process of assembling the device
so the mother board goes
in first and the the funny thing is the
cpu for the motherboard has some paste
on it
if you noticed so we're gonna
reinstall the battery
be very careful not to misalign it
because uh as you can you know the
battery that
is exposed to punctures or
misinstallation can
cause fire hazard and even explosion
as with other smartphones so yeah you
have to have
a professional service to disassemble
your device
and professionally reassemble it to
ensure your safety
so do we recommend beginners or
enthusiasts to
do it on their own yeah maybe if you
have the right tools and experience
and training you can but if you don't
have
any of those
even if you have two of those if you
don't have experience or skills or tools
then maybe you should opt out for a diy
approach
and seek a professional service to
repair your huawei mate 30
so you can see here it's fully revived
and
looks almost brand new
so just the final screws and the back
glass and we're almost done
