Despicable Me: Minion Rush issue

[calinoi]

Hello everyone! I'm a newbie in this dark part of android named hacking ). I read all about GG and I followed step by step the tutorials to se t up and hack my game,Minion Rush.I found the coins value,modified it but it doesn't change at all. I read all faq and general help but couldn't do it. I'm running stock rooted firmware on my Galaxy S3 4.1.2. Please help me,as I don't want an mod apk with infinite coins and tokens,I just want a moderate ammount.

Ps: I set my temp path to /sdcard and instead of enable lock button it shows me Donate button :-/

Thanks
