DSi factory Reset

Hey, my friend was being a dick, and he put random sh*t in my DSi, and made parental controls with a random question and random answers on everything. I dont want to call nintendo for his idiocy, so I was wondering if you guys knew how to factory reset a DSi. i tried pressing LR start select d-pad but it didnt work and just sends me to the touch screen calibration.FUUUUU-

A factory reset on the DSi can be performed by holding down every button minus those of the d-pad and turning the system on.

So thats L R start A B X Y select all at once? Because I think I tried that....

That's where I got it from, lol!
Start & Select, remember!

factory reset may not remove parental controls.

Ah ffs, I'm going to kill him

Why not ask him? it's yours, the DSi, I mean...

if he put random stuff in, he doesn't know what it was.

Try removing and reinserting battery pack .

I will, I just need a screwdriver...

You'll need a Tri-wing.

My NDS lite has "+" not a "y" screw on battery cover.

I made my own security screwdriver for those screws.

i tried holding every button down minus the d-pad and turning it on but it just took me to calibration :S
please help :(

???what you have to press buttons for ???
