Pull the SD card out. Try again.
Can a PC see anything inside it, if you hook it up via USB?
Try OPPO safe mode boot.
If that doesn't work, you may have to hard reset the OS and reinstall it.
yeah the usb debug thing is off, its on charge only and i cant change because it has to actually turn on.
I think the sd isnt removable like the battery. I tried the safe mode and it didnt change the normal startup when I pressed and held the bottom volume key. Also, hard reset it also one of the first things I did.
