    Unhappy MBP won't boot...pls help [VIDEO]

    Hi, I'm having serious troubles to figure out what's wrong with a mid-2012 13" MBP.

    Basically upon turning it on, it shuts down a bit short after the progress bar with the apple logo appears. Pls refer to this video:

    I've tried all this and always see the same behaviour:
    • Resetting PRAM & SMC
    • Swapping RAM with that of another working Macbook
    • Swaping the hard drive with that of another working laptop
    • Booting in safe mode (command S)
    • Booting with a USB drive with a bootable image of OS Sierra

    I ran the onboard diagnostics (command D) and came up with no hardware errors.

    I don't know what else to try.

    Input greatly appreciated...
