Sony\’s starting to get a little quicker with their firmware releases! But despite the fact that this new firmware "Strengthens Security", it\’s confirmed that it works just fine on Devhook v0.51. The only thing you must do to Devhook is uninstall the flash1:/ files and reintall them so that 3.02 will work properly. If you\’re feeling adventurous, try it out for yourself!

Still don\’t believe me? Here\’s a video made by Emeriastone of 3.02 working on his 1.5 PSP
