Hello everyone, my friend has a system that can be downgraded. We checked the serial model version, and it says CECH-2501B. Would he need to purchase a E3 Flasher, or would he need to buy something else? I've watched a video saying something about if it's above A-G, you would need to buy something else besides a E3 Flasher. What I dont understand is that his Model ID says 'CECH-2501B so... does it make the system a B?
