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.The common feature of all custom firmware available for the PSP is to relax the signing process for PSP applications, so that applications that developers that aren’t Sony approved can be installed.All forms of CFW will mention whether or not they are permanent.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.
Open 661 PRO-C Fast Recovery (PRO), and wait for your PSP to reboot.You no longer need to open up fast recovery, or even keep any of the custom firmware utilities on your PSP.However, your PSP must be able to support this as certain models do not.You can play games in the UMD drive, you can play games you bought from the store, but when it comes to trying to play games in an unconventional manner, you will hit a road block.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.
