    • Insert a SIM eject tool, bit, or straightened paper clip into the SIM card tray hole on the top edge of the phone.

    • Press firmly to eject the tray.

    • Remove the SIM card tray.

    • If you accidentally inserted the SIM eject tool into a microphone hole, don't worry! You most likely didn't damage the microphone.

  2. Samsung Galaxy Note20 Ultra Motherboard Replacement, Heat the rear cover: шаг 2, изображение 1 из 1
    • Completely power off your phone before you begin disassembly.

    • Heat an iOpener and apply it to the left side of the rear cover for one minute.

    • A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the screen and internal battery are susceptible to heat damage.

  3. Samsung Galaxy Note20 Ultra Motherboard Replacement, Insert an opening pick: шаг 3, изображение 1 из 3 Samsung Galaxy Note20 Ultra Motherboard Replacement, Insert an opening pick: шаг 3, изображение 2 из 3 Samsung Galaxy Note20 Ultra Motherboard Replacement, Insert an opening pick: шаг 3, изображение 3 из 3
    • Apply a suction cup to the heated edge of the rear cover, as close to the edge as possible.

    • If your back glass is badly cracked, covering it with a layer of clear packing tape may allow the suction cup to adhere. Alternatively, very strong tape may be used instead of the suction cup. If all else fails, you can superglue the suction cup to the broken panel.

    • Pull up on the suction cup with strong, steady force to create a gap between the rear cover and the frame.

    • Depending on the age of your phone, this may be difficult. If you are having trouble, apply more heat to the edge and try again.

    • Insert an opening pick into the gap.

    • Don't insert the opening pick more than 5 mm into the phone or you risk damaging the internal components.

    • While cutting through the adhesive, don't insert the opening pick more than 5 mm into the phone or you risk damaging the internal components.

    • Repeat the process of heating and cutting the adhesive along the three remaining sides of the rear cover.

    • You can insert each new opening pick in the gaps created by the opening picks left in each corner.

    • As you proceed, leave an opening pick in each corner to prevent the adhesive from re-sealing.

    • Slide an opening pick back and forth around the entire perimeter of the phone to release any missed adhesive. Reheat any stubborn adhesive.

    • Use the pointed end of a spudger to pry up and disconnect the wireless charging coil press connector.

    • Take care to pry only under the edge of the connector to prevent damaging the socket itself and surrounding components.

    • To re-attach press connectors like this one, carefully align and press down on one side until it clicks into place, then repeat on the other side. Do not press down on the middle. If the connector is misaligned, the pins can bend, causing permanent damage.

I went to a water park and the phone was soaked in water. I left it in the rice container for 3 days out in the sun and it finally booted up. The phone was in airplane mode, no wifi, no network. I did a reboot and still nothing. When i ejected SIM tray it said no SIM found but when i put it back in, no network or wifi. I tried to reset wifi and network several times but didn't help. I cannot do a factory reset because it says i needed wifi. At this point im guessing these 2 features are on 1 component and it got damaged somehow. What part do i order so i can swap out and bring my phone back to life? Thank you
