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.
You can find me on IRC, Discord and Twitter

Thanks, tab is already removed.

Shot in the dark here, but do you press and hold the power button for >10 seconds? Mine requires 10 seconds.
"- is there already a tool for overclocking it desperately?"

Do you have the original firmware for factory test ? to flash it please, i think this is the electronic card

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.
