What if you press and hold power & Volume up for 5 seconds > charge the phone and repair it with PCC

Nothing. My computer made the little chime when I plug something into the usb port but my computer isnt reconizing the phone. The blue notification light is still flashing on my phone but the screen still wont come on

Open the SD card port > press the red button, don't press it too hard.

No red button. Only yellow button in the sim card port

Press that.
Hold it for 5 seconds til it vibrates

Held it down for 5 seconds no vibration. Held it down again fir more than 10 seconds and still nothing

Connect the phone to a wall charger > press and hold power & volume up for 10 seconds > let it charge for about 1 or 2 hours > then try again with PCC

I removed the sim. Waited 5 minutes put it back in and held the power and vol down button for 15 seconds and it restarted my phone and the screen came back on
