I'll keep this short. I have a 120 GB slim that I want to mod. I've been doing my own research on this and came to a conclusion that I need to find a custom firmware that can be used with the 4.3 ofw. My overall objective is to play back up games while maintaining my usage of online-- since all the games I play are majorly focused on Online interactions. If anyone can help me with this I'll be greatly appreciated. I'll keep looking around the web site for anything.
