Just a note: If the battery runs down very low it can take hours before it will recognise a charging input.
- Check the voltage if you can below 3.5V is a problem
- Try alternate cables and charger
- Leave each option to charge for a few hours and do not attempt to power on the phone
- Clean the USB C port
- Search the forum for more DIY options on [ bottom module] etc.
Have you tried an angel yourself.
Hopefully you will see a red or yellow LED
