CFW 5.50 GEN-D3. I upgrade again

Yes, I upgrade my psp firmware again... for 2nd time. What is the reason? The reason is that my 5.50 GEN-B firmware is not able to open Kingdom Heart Sleep by Birth :(


This is the latest game from Square-Enix which required OFW 6.20. Since you unable to open the game, what will you do. I straightaway go find my friend named Google. After a few search, even with the latest CFW 5.50 GEN-D3 the game was unable to open due to the security block inside the ISO file :(

Well, for those who still want to upgrade to 5.50 GEN-D3. There's one big advantage using this CFW whereby you do not need to decrypt your ISO anymore in order to load the game which require OFW 5.50 - 6.00. Hooray!
