Updating psp through usb
If you installed a 6.60 CFW on 6.61 OFW you could potentially brick your device. Extract this folder and you should see a folder named either PSP or GAME. Connect your PSP to your computer via USB, and go to USB Connection mode.
Once it appears in your File Explorer (It’ll appear like a memory stick), open it up.
Once done, you can now disconnect your PSP from your computer. You should now see some new exciting options (examples from PRO-C)! Prepare a brew and dig out the biggest pack of biscuits you’ve got, this is going to take a while.
Open 661 PRO-C Fast Recovery (PRO), and wait for your PSP to reboot.
While the update isn't required (single player games can still be played without an Internet connection), it is recommend that you install it to receive the full benefits of Sony's latest console.
If you try to play a backup copy of a game, activate a non-sony theme, or install an emulator you will find you can’t progress in some manner. Custom Firmware (abbreviated CFW) relaxes restrictions put in place by Sony, and allows you to do much more than you could do before with your PSP.
Please check out our Infinity guide instead for installation on semi-permanent capable devices.
All cfws like to modify the system information screen to show what custom firmware you’re running. If ‘System Software’ shows just a number and your full mac address is shown, then you are running official firmware. Official firmware 6.61 has been cracked, and comes with internal system fixes.
A permanent CFW is when you turn off your PSP by holding the power switch or running out of battery, and you see the ‘Sony Computer Entertainment’ boot logo, the CFW remains installed.
If the CFW is not permanent, when you restart it returns back to the original state.
