Why would i want to install Custom Firmware on my PSP? So you can now follow this guide if you happen to have updated to 6.61. It's of no benefit to you updating to 6.61 after all this time, however the custom firmware has now been updated to support 6.61. Note: On the Sony released PSP firmware 6.61, some three and a half years after the last 6.60 update. The PSP Custom Firmware 6.61-Pro-C2 will work on all PSP models from the original PSP to the PSP Go and even the E1000, all you need is to be running the official 6.60 or 6.61 firmware to install and use this custom firmware.
