Hi everyone, Welcome back to geardo,
Today we will show you how to replace the lcd screen
on Xiaomi Redmi Note 7 / Note 7 Pro Mobile phone.
To start, we need to have the right tools to proceed with the repair,
which You can find in the description.
First, turn off the phone, and then follow the back cover removal.
To remove the back cover, it needs to heat gently
around the rear cover edges until the pasted adhesive becomes soft.
For this, we are using a heating pad. Place the back cover side on
the heating pad and Select the mobile phone HEATING option and leave it till
it completes. Alternatively, you can use a heat gun or hairdryer.
Once the heating has completed,
Use a suction cup to create an opening between the frame and rear cover.
Next, insert a plastic card pry tool or something similar to cut the adhesive around the back cover.
While opening the back cover, be gentle, the fingerprint plug connects with the back cover.
Next, take out the bracket by undoing three screws and then disconnect the battery plug.
Next, take out the back cover by releasing the adhesive and disconnecting the fingerprint plug.
Next, disconnect the lcd and main flex plugs from the logic board.
Next, take out the speaker cover by undoing eight screws.
Next, take out the battery.
First, loosen both adhesive tabs on the bottom,
and then gently use your fingers or tweeze to pull out the adhesive strips.
If the sticky is strong, apply heat to soften the battery. And then,
use a pry tool to cut the adhesive under the battery.
Next, pull out the main flex by disconnecting the other half of the main flex.

Now the only remaining part is the broken front screen assembly with the frame.
For the replacement, there are two different screen types in the market. The one is with the
frame, and the other is without the frame. It can be original, used, or aftermarket.
Either version you choose, you can get with the frame and without. But the most
straightforward repair will be with the frame, and also, the price difference is not that big.
I recommend you go with a screen with a frame & buttons installed. It can be original,
refurbished, used, aftermarket. And this type is commonly available to purchase.
Next, on the new screen frame, start placing removed parts.

verify the functionality by powering up the device.

Next, Before installing the main back cover, make sure it has enough glue;
if not, use B7000 glue or a new double-sided back cover adhesive.
