基本是你得换好几次，正版→烧录→正版→烧录
STEP ZERO:
首先找个东西把开盖按钮卡住
STEP ONE:
Insert black bottom disc (Official pressed disc)
STEP TWO:
Power on console, the disc should begin to spin at 1x.
If it doesn't, it means that the lid sensor isn't covered properly.
STEP THREE:
When the Black "PlayStation" logo appears on the screen, the disc should speed up to 2x.
When you hear a noise from the PlayStation, and the disc slows down a little, as quickly as you can, replace the disc with your backup.
STEP FOUR:
The disc should speed up to 2x, for a bit, then again, it'll slow down, this is when you remove the backup disc, and replace with the official disc.
STEP FIVE:
Now, this is the tricky part.
When you inserted the official disc, the PlayStation logo should still be displayed, but, a few seconds after, it's really fast, could be one second after you insert it, the PlayStation logo should disappear, and you'll see a blank screen.
As soon as it disappears, you have about 1 second to replace it with your backup disc, timing is crucial.
As soon as you put the disc in, wait about 5 seconds, and it should boot, maximum of 1 minute of waiting.
If the disc doesn't boot, you've either got a bad disc, or you timed the swapping wrong.
