Since Davee (the creator of ChickHEN) made it possible t downgrade from 6.31/6.35 to 6.20. Once at 6.20, thanks to Total_Noob you can fake your version, and index files, and run the 5.03 update (only on PSP 3000 models with the 03g Module, anything higher than 03 will brick) once at 5.03 you can use ChickHEN and GEN for HEN. :D

Its a beautiful new age we live in :D
