P10 lite - Replacing the screen

Switch off the device.

1. Press and hold the Power button, until you see a menu.
2. Choose the Power Off option and tap again to confirm.

1. Take out the SIM tray by sticking a SIM tool into the small hole.
2. Take out the SIM tray and put it aside.

Be extra careful with this step, as splintered glass could injure you.

The back cover is glued to the display chassis. So you need to heat the back cover and pull it off using a suction cup.

1. Place the suction cup as low as possible on the back cover, over the text.
2. Pull on the suction cup while pressing the frame against the table using a pick. As soon as a gap between the frame and the cover opens, you can carefully stick in your pick.
3. Move the pick along the device edges to unglue the cover all around.

1. Carefully lift up the back cover. Fold it up along the short edge of the device. You should be able to see the flex cable now.
2. There's a small tape strip over the flex cable connector on the back cover. Pull it off and then use tweezers to pull the cable out of its socket. Keep the tape strip to attach the flex cable later.
3. Once the back cover is disconnected, you can put it aside.

• 1 × 2.7 mm Phillips

1. Remove the screw on the battery connector's bracket. The bracket is latched in on the other side, so remove it carefully.
2. Now you can unplug the battery.

You can remove the mainboard to get to the battery more easily. You can see the steps in the display replacement guide.

Careful: The battery bends very easily. Heat the display several times until the glue is very soft and the battery comes out easily. You can also try pulling off the battery with a suction cup, if the glue isn't too strong. Or you can order a new battery with your display and discard the old one.

1. The battery glue is very strong. To get it off, you need to heat the device from the display side using a heat gun. Don't heat the battery directly.
2. Then slide the broad end of the battery spudger under the battery on the long, upper edge. Here the glue strip is a little thinner than on the other sides.
3. When the battery comes off on one side, you can pry all around with the spudger and unglue the other spots.

• 7 × 2.7 mm Phillips

1. The speaker is part of a plastic assembly. Remove the 7 same-length Phillips screws on the lower plastic cover and put them in the same box of your magnetic pad.
2. The unit is clipped in around all 4 sides. First unclip the short edges at the top and bottom by prying out the with a flat tool.
3. Now take out the speaker unit and put it aside.

Work carefully. If the cover doesn't come off easy, pry again, so you don't break it.

• Connector

1. Unplug both connectors of the large flex cable between the mainboard and the sub-board.
2. Slide a flat tool under the flex cable to unglue it. Use some hot air, if necessary.
3. Take the flex cable out of the device and put it aside.

• 2 × Antenna plug

1. There's a thin antenna cable over the battery connecting the mainboard and the sub-board. Use a thin spudger to unplug the antenna on both sides.
2. Take the antenna cable out of its holder.

The USB port is installed on the sub-board.

1. The board is glued on a bit, so heat it a little.
2. Now you can slide a tool under the sub-board and pry it off.

You can leave on the audio port's rubber cover.

• 1 × 2.7 mm Phillips

You can take off the small flex cable of the fingerprint sensor from the mainboard. You can also leave it on, unless you need to clean the mainboard.

1. Remove the single screw on the mainboard.
2. Stick the flat end of the spatula between mainboard and frame on the top edge. First pry out this side. THen you should be able to pull out the mainboard towards the top. It breaks really easily, so be extra careful!
3. The bottom side of the mainboard has some pink thermal paste. Scrape off the residue with a spudger and carefully smear it on the mainboard. This improves heat conduction when you reinstall it.

The earpiece is slightly glued. You can first heat the glue with a heat gun.

1. Use a flat tool and carefully pry out the earpiece and put it aside.

The chip for the standby and volume buttons sits in the frame sideways under a plastic cover.

1. Take out the plastic cover with tweezers.
2. Then use a flat tool to unglue the chip and then pull it out.

The spare part has stickers for the battery, the rear camera, the earpiece, the PCB flex cable and the USB sub-board.

1. You can leave on the protective films until you install each part. This prevents parts from sticking by accident. You can also pull off all films first, like in this guide. If you do, take care not to stick on any parts by accident.
2. Take the small, red rubber from the bottom end of the old display and stick it into the new display.

1. Insert the chip with the contacts for the standby/volume buttons into the new display.
2. Test if the buttons are clicking if you press them.
3. Then attach the plastic cover for the buttons and press it in.
