PS2 Version 7(Hope Not)

[TMACMARION]

I have a question, I sent in my PS2 sometime near Christmas, I'll say December 23rd, when I sent it in, do you think they made it so I couldn't use the knife trick, I sent it in because it got dropped, and it needed repairing, they just replaced some parts and sent it back and it was fixed, do you think they made it so that the knife trick wouldn't work, like they did to the V.7 systems.

Thanks In Advance
