True to their word, the GEN Team has now released Custom Firmware 5.03 GEN-C. It’s an update to their existing line of 5.03-based firmwares (5.03 GEN-A and 5.03 GEN-B) that will allow you to play games that require upto 6.10 without running the decrypter to patch the game.

Important Notes:

This guide is for non-hackable PSPs. (PSP-3000 / PSP-2000 TA-088v3). If you’re not sure what PSP you have, please read: Is my PSP hackable?

Unlike custom firmware for hackable PSPs, the danger of bricking your PSP-3000 / PSP-2000 TA-088v3 is quite real. If you’re not sure about a step, take the time to post a question.
