Just recently cleaned corrosion off of the main board that was near where the battery connects and plugged every thing back in. Showed the charging symbol and LED for about 15 seconds and showed a temperature warning for about a minute. Now the phone is refusing to turn on or to even charge for that matter. Edit: I disconnected the battery and it did it repeated what it did above, only when the battery is disconnected.
Make sure the wireless charging coil is connected and making good contact with the pins on the board. There’s a temperature sensor attached to the coil and if it’s not working or not reading it, the phone will refuse to boot or charge because it’s not getting accurate temperature information.
