Make a Trainer with Exp Booster

Hello everyone, to begin sorry for my english. So, I want to make some trainers ( unlocker medalls, guns... ) and for that i use the adresses give by kendoyavuz ( Thanks to him ). So i begin to watch adresses and i saw that ( The picture (link) of the adresses where we can read : PRETIGE then EXP... I suppose that it's a bad idea to touch to the prestige, but the exp, you just past pretige then go barraks, change exp, past prestige...Is it dangerous ? Thanks for your answers and sorry for my very bad english :(

If you hack the Level you become a Error by joining a Match, you can't play then.
The same with the Prestige.

The only one that can fix the Error problem is reset your whole Stats.
