Thanks Trod80,
My PSP Firmware is 2.01.
I already downgraded to 1.5 and format my memory card.
Now I download your package and see 3 folders inside.
Which one should I use?
(2) To Upgrade To Version 3.10OE-A (after you have downgrade to 1.50) ?
After I format the memory,
Does the PSP still keep the official firmware 1.5 and have a capacity of 3.10 firmware?
Does it work similar to Devhook?
I am worry about my PSP would be no longer play homebrew games after upgrading to 3.10.
Hope you help and I really appreciate your hardwork.
