Hello, first off, let me apologize if this has been asked many times before. With that said, let me get into my question. Although I'm extremely late to the party, I recently purchased a PSP, as I was bored with my other handhelds. I've used GBAtemp before to homebrew my Wii, so naturally this was the first place I decided to check on how to jailbreak my PSP. I found this guide: http://gbatemp.net/topic/291169-hack-every-psp-up-to-firmware-660/ and it seems to be reliable and detailed. However, I couldn't find whether or not it was possible to downgrade the 6.60 firmware to 6.20 so I could use 6.20 PRO as opposed to 6.35 or 6.39. (I want to have it permanently instead of re-doing it everytime I boot the PSP). My PSP's Model is 1001 And I'm currently running the 6.60 firmware. So, am I able to downgrade from 6.60 to 6.20 using the downgrader used in the guide? Again, I'm sorry if this has been asked before. Thanks!
