Updating PSP to 6.60: Connect the PSP system to the PC using the USB cable. Since the PSP E1000 can only install the firmwares (6.50 as pre-installed, no installer available) 6.60 and 6.61, and the downgrader can not downgrade to 6.60, it (the PSP E1000) is currently not supported by the 6.61 downgrader.
