A slight possibility, loose battery connection?

Thank you for your suggestion. The same happens when the phone is connected with a USB cable, so I don't think it's a loose battery connection...

Remove the little tab between the battery and mainboard pins.

Shot in the dark here, but do you press and hold the power button for >10 seconds? Mine requires 10 seconds.

pretty sure it's the loose battery. im having the same issues, I haven't managed to power it on without putting on the battery cover and pressing it very tightly to make sure the battery is in place. Put the phone in my backpack and went for a ride, that seems to have moved the battery and the phone was powered off until I could re-seat the battery properly.
