Thread: Question about 3.55 and 3.70

hi guys , it seem some games are require to update your firmware to 3.70 so you able to play the games but my question is can i go back to my old firmware which is 3.55 ?
and ahhh i remember something else how can i play ps one my psn download games are working but why ps one aren't what should i do to make them work .

u can go back to 3.55 if u use a progskeet. it requires a tremendous amount of soldering though.

u should be able to get those psn games working with reactpsn.

Thanks alot Rep+.

downgrading is not possible unless you have a hardware flasher like progskeet or e3 flasher. So you simply cant revert back to 3.55. You can activate your psn/ps classics using reactpsn. You can find more details in tutorial section

Downgrade is kinda hard. But a lot of users overcome this difficult buying 2 consoles... one to play backups (3.55) and the other will be sony friend (4.00)...
