Any OFW downgrader to all most all firmware
6.60/6.39/6.38/6.35/6.31 Downgrader By Davee, ported to 6.60/6.39/6.38 by some1 [What does it do?] Allows users who are incontent with their firmware to downgrade to 6.20 using the Sony Updater. [How do I use it?] Copy the "PSP" folder to your PSP. The downgrader is "signed" and can be launched from OFW XMB. You need to copy the 6.20 update to PSP/GAME/UPDATE/EBOOT.PBP and for PSPgo it must be the eflash it is placed on. After setup run the downgrader and follow the onscreen instructions. [What does it technically do?] 6.20-6.35: It uses the utility/power exploit to gain kernel access and reboots into the updater with a special PRX running. This PRX uses the pspdecrypt functionality to decrypt the updater PRX when needed. This allows the updater to boot in the newer firmwares. 6.38/6.39: It uses my http_storage exploit to gain kernel access. Basically, http_storage has a vulnerability in it, where I can write -1 to anywhere in memory. (I'll make a post to explain it more in-depth soon) [I'm a dev, sup?] Not this time sorry, will maybe be added in later. [Credits] Davee - legend. Originally made 6.35/6.31 downgrader bbtgp - legend.
