Hello, I had a psp 1.52. I successfully downgraded to 1.50 by updating to 2.0 then downgrade to 1.50. I recently installed Dark Alex's 3.02 and devhook 5.1 not sure which version. What i would like to do is upgrade to 3.03 OE-A or OE-B. Is there a guide or can someone help me how to do this. Thanx.
