Step-by-Step Process
Step 1:
Insert a SIM card eject tool, a SIM eject bit or a straightened paper clip '''into the hole on the SIM tray''' located at the left side of the phone.
Press firmly to eject the tray.
Remove the SIM card tray.
When reinserting the cards, make sure to properly orient them in the tray.
Step 2:
Before beginning this procedure, completely power off your phone.
Prepare an [https://www.ifixit.com/Guide/iOpener+Heating/25705|new_window=true|iOpener] and apply it to the back cover to soften the adhesive.
The adhesive of the Samsung Galaxy A51 is very strong. You can use a hair dryer or a heat gun if you aren't able to open the device with the iOpener.
Be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.
Step 3:
Insert the tip of an opening pick between the frame and the back cover at the bottom of the phone near the USB-C port.
If you can't get between the back cover and midframe with your opening pick, you can use a suction handle or [https://d3nevzfk7ii3be.cloudfront.net/igi/4MmKE22Cy2MavVZU|strong tape|new_window=true] to pull up the back cover to create a gap.
Slide the opening pick to the bottom right corner and leave it there.
Step 4:
Insert a second opening pick and slide it from the bottom right corner to the bottom left corner to cut the adhesive.
Leave the opening picks in place to prevent the adhesive from resealing.
Step 5:
Insert a third opening pick under the bottom left corner of the back cover.
If you have any trouble, apply more heat to further soften the adhesive. Follow the iOpener instructions to avoid overheating.
Slide the opening pick along the left edge of the phone.
Leave the opening pick in the top left corner to prevent the adhesive from resealing.
Step 6:
Insert a fourth opening pick under the top left corner of the back cover near the camera.
Slide the tip of the opening pick along the top edge of the phone to the right corner to cut the adhesive.
Leave the opening pick in the top right corner to prevent the adhesive from resealing.
Step 7:
With opening picks in all four corners, insert a fifth and final opening pick under the top right corner of the back cover.
Slide the tip of the opening pick along the right edge of the phone to the bottom right corner to cut the remaining adhesive.
Step 8:
Remove the back cover.
After installing the back cover, apply strong, steady pressure to your phone for several minutes to help the adhesive form a good bond—a stack of heavy books works well.
Step 9:
Remove the thirteen 3 mm Phillips #00 screws securing the midframe.
Step 10:
The midframe is held in place by plastic clips.
Insert an opening pick between the midframe and front panel assembly on the bottom of the phone near the charge port.
Slide the opening pick to the left bottom corner to release the plastic clips.
Slide the opening pick to the bottom right corner to release the rest of the bottom plastic clips.
Step 11:
Continue sliding the opening pick on the right side of your phone until all plastic clips on the right side are released.
Step 12:
Slide the opening pick along the top edge to release the top plastic clips.
Step 13:
Slide the opening pick from the top left corner to the bottom left corner to release the left side's plastic clips.
Step 14:
Remove the midframe.
Step 15:
Use the flat end of a spudger to disconnect the battery by prying the connector straight up from its socket.
Step 16:
Use the flat end of a spudger to pry up and disconnect the display flex cable on the bottom of the phone.
Step 17:
You may need to reheat and reapply the iOpener several times to get the phone warm enough to cut the adhesive. Follow the iOpener instructions to avoid overheating.
Step 18:
Once the screen is warm to the touch, apply a suction cup to the upper edge of the phone.
If the screen is cracked, the suction cup may not stick. Try [https://d3nevzfk7ii3be.cloudfront.net/igi/4MmKE22Cy2MavVZU|lifting it with strong tape|new_window=true], or superglue the suction cup in place and allow it to cure so you can proceed.
Insert an opening pick in the gap and start to cut the adhesive by sliding it to the top right corner.
Step 19:
Insert a second opening pick and slide it to the top left corner.
Leave the opening picks in place to prevent the adhesive from resealing.
Step 20:
Insert a third opening pick and slide it along the left edge to cut the adhesive.
Leave the opening pick in the bottom left corner to prevent the adhesive from resealing.
Step 21:
Insert a fourth opening pick and slide it from the bottom left corner to the bottom right corner.
Leave the opening pick in its place to prevent the adhesive from resealing.
Step 22:
Insert a fifth opening pick and slide it along the left edge of the phone to cut the remaining adhesive.
Step 23:
Reapply a heated iOpener to the screen to loosen the adhesive underneath.
As you wait, take note of the rectangular-shaped adhesive placed underneath the screen.
Step 24:
Insert a [product|IF145-101|plastic card] on the left edge into the gap between display and the phone assembly.
Press the plastic card in and slide it back and forth until you cut through the entire adhesive.
Once you are sure you cut through the adhesive, remove the four opening picks from the corners.
Do not remove the screen completely yet. The display cable is still threaded through the frame.
Step 25:
Carefully thread the display cable through the frame.
Step 26:
Remove the screen.
