Image unavailable (removed by its host)6.60/6.39/6.38/6.35/6.31 DowngraderOwners of Psp on firmware 6.60 are going to be happy, because Some1, a developer from the Wololo forum, has just released his
6.60/6.39/6.38/6.35/6.31 Downgrader.Which will let you go from Psp firmware 6.60 to 6.35 (for the latest Psp GO as well as for the 7g and 9g models.From 6.60 to 6.20 for all other Psp.This downgrader is inspired by Davee's 6.35 downgrader.Here is Some1's message about this downgrader
Important Note: This Kernel Exploit was NOT found by me. It was handed to me by Zecoxao, and it was handed to him by Davee.
Another Important note: You run the application at your OWN risk. I am not held accountable if you screw up your PSP.
After a long wait, here is the port of Davee's 6.35/6.31 downgrader to 6.60/6.39/6.38.
This is a very simple app, just put the desired destination OFW in PSP/GAME/UPDATE, and the app will read the factory installed OFW (aka, the OFW it came with), and allow any updater greater than or equal to this OFW. The range for this has NOT been tested, so I do not know which OFWs it is possible to downgrade to, for which model, but I've tested from 6.60 to 6.20 and 6.35, 6.39 should also work. If you use the wrong updater, the update itself will error out or go back to XMB.
Change Log:
v4.1
Added Source Code
Added Safety net just in case, for some reason, your psp does not have the 0x51 key, the safety net sets minimum version to 6.35 if you were getting an error from v4.
Includes Proxima's prxencrypter with gzip support.
v4.0
Added Support for 6.60
Fixed 6.60 problem that didn't allow to downgrade to anything greater than 6.20, thanks to Davee
Allows any updater that is greater than or equal to the factory installed OFW (Has not been fully tested, will most likely work on 500 and up)
Special Sauce added by Proxima

Installation Copier le dossier Psp à la racine de la memory Stick ou de la PSPGo.
Lancez le downgrader depuis le XMB dans la catégorie jeu et suivez les instructions.
Lorsque l'installation est terminée, redémarrez la PSP et vous obtiendrez un écran bleu avec des messages d'erreur dans des langues différentes, ne vous inquiétez pas, c'est normal, appuyez simplement sur le bouton (O) et voilà c'est fini.Si votre firmware officiel a un problème, le downgrader le detectera ! External content (video or audio) hidden: it sets its own cookies.Ceci est une video du downgrader 6.39 !Comme tout logiciel qui touche au flash 0 de la Psp, il y a des risques de brick.
Tgames et les concepteurs des programmes, ne peuvent être tenu comme responsable en cas de brick (toutes installations ou mise a jour se fait batterie pleine et sur secteur, ne pas arrêter la Psp en cours d'installation, etc...)Si vous ne savez pas si votre Psp est downgradable, vous pouvez identifier votre Psp avec psp ident, ça se passe par ici.Télécharger 6.60/6.39/6.38/6.35/6.31 Downgrader V4.1

Good evening and a big thanks to some1 But I have a small problem, I managed to downgrade from OFW 6.60 to OFW 6.20, but I don't know how to reinstall a custom firmware (the 6.39me 9.3 me would make me happy^^). Would someone be kind enough to describe step by step the steps to follow to reinstall this CFW please because I'm struggling (I'm quite a noob with PSP). Thanks in advance
