Are you sure you are S-On?
To get to bootloader : when phone is off, hold volume down and press power button.

Edit: You sound like you know what you are doing. (wow, you are smart for your age.)
So, my advice is drop the phone in the toilet, it will be more forgivable to your parents, than "hacking" it. (as it's most likely a paper weight if you are on 2.16 and S-on) lol
Edit 2: Ok, that's bad advice, maybe someone (or even you) will come up with a way to fix it.
