I hadn't seen this message earlier, but here's a warning:
I haven't seen the video, nor I'm going to watch it, I don't have time for that.
But, I did not tell you to do this, if you lost any data or permanently lost access to your data because of the said video I'm afraid I can't help you any further. You should contact a qualified technician in your area.
Like I said on the previous post, the only way to know if it has been repaired or not is to change the boot order and boot it.
