6.60 Downgrader by some1
Are you one of the poor souls who upgraded to 6.60, before realizing you were stuck in a dark place that doesn’t allow you to run a Custom Firmware? Well you’re lucky, it’s rare that a downgrader is available that soon after an Official Firmware release. Some1 is at it again, and updated the 6.xx downgrader to support Firmware 6.60. So you can now downgrade from 6.60 to any firmware you want (provided your motherboard allow it, but don’t panic, the downgrader will let you know). Most users will probably want to downgrade to the closest firmware, 6.39, in order to install Pro CFW.
It seems Davee, Proxima, and Zecoxao were also directly involved in this release, so many thanks to them for their continuous involvement in the PSP scene.
Was this release too early and a “waste” of a Kernel exploit considering the upcoming launch of the PSP Street? Only time will tell. In the meantime, you can download the Downgrader here.
Congrats to some1
