I can't alter reputation value directly, but I have another way to increase reputation quickly. 1. Enter any race. 2. Do any combo, search address for the combo value. 3. Change the value to 50, and LOCK IT. 4. Now you get reputation point for every second you race. 5. At the end of race, you will get tons of reputation point, enough to increase your rank to 80 (max).

I think it happen when super user doesn't allow GG to access root. Try open super user, on settings - automatic response, set to allow. It fixed my problem.
