to proceed with the repair, which You can find in the description.
First, Take out the Sim tray and then the back cover removal.
To remove the back cover, it needs to heat gently
around the back 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 around the back cover edges until the pasted adhesive becomes soft.
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 pulling out the back cover, Be gentle; the fingerprint is attached to the back cover and the
board. First, Disconnect the fingerprint plug and then take out the back cover.
