hello thank you to listen to me, excuse me but my english are something poor and I am using a translator.
before using the fusa plugin my buttons of + and - volume worked perfectly but after using the fusa it doesn't work and disable the sound for the speaker of the psp, i downgrade my psp a la version 4.01 to the version 4.01 and anything is to sound then it upgrades it to the 5.0 m33 -4 and it upgrades it to the version m33-6 and it doesn't sound.
trying discovered that if it sounds but with the cable of av of 3 plugs and of 5 plugs too (i have 2), pluged to tv but without image (it is as if you not to disable the fusa pluging).
the disconcerting thing is that if I enter to the menu recovery and format or reset de flash 1 memory the psp it sounds again again but when I am try use the + or - buttons the volume another time is silent and only sounding for the tv.
please i like my psp go to normal help please.
