i wanna do the glitch where i join a persons party that has everything then back out at a certain time and then ill become level 256 or something along those lines.I used Horizon to mod mine.
I can modify it for you. Take like 2 minutes .
That requires him to give you his account though since the levels are stored on the profile itself. Not saying you are untrustworthy, just saying it is risky no matter who you deal with.
Unless he knows how to extract the .gpd from his account. Then the guy can hex edit it.
