Gaming [HELP] Mario Bros U Disc not loading

[THEELEMENTKH]

I was trying to play my New Super Mario Bros. U + New Super Luigi U disc with my brother yesterday.

When I bought the game (It was used) it worked perfectly, but since last week, the game just doesn't load ANYTHING (It gets stuck on the screen that shows when a game disc is loading), it doesn't make any spin sound, and the only way I can end this is by holding down the power button.

Anyone knows what can I do?

(BTW, it's a PAL/EUR Wii U FW 5.5.1 with Loadiine GX2 [Dunno if it's helpful, but who knows...])

Just making sure, but you have tried a different disk right? Sounds like the drive is failing to me

Yes, I've tried every Wii U game I have and only Mario Bros. U has this problem, the others work without a single problem

Cleaned the disc? Has it's become scratched or damaged?

Yep, I've cleaned it several times with no luck
And the disc has no scratches at all (Checked it at least three times)
