semi bricked fat psp help please

[Jet_Luger]

I have a pretty old fat psp and it was just bricked when i was trying to downgrade it to 1.50 from 3.03 OE-A. Its only semi bricked because i can still acess the menu on start up when you hold down the right trigger. is there any way that I can unbrick it using some recovery eboot or some other method that wont involve using the pandora battery technique.
