A new custom made firmware upgrade for hacked PlayStation 3 consoles has been launched, and this one looks like it’s going to be pretty permanent. It’s even compatible with the 4.25 firmware release.

It’s basically based on the PlayStation 3’s LV0 keys. With the help of the LV0 decryption keys, firmware upgrades can easily be decoded. A firmware update can be transferred to PCs, decoded and then transferred back to a hacked PS3 console (via Eurogamer).

The LV0 keys have been made by a group called “The Three Muskateers”. A Chinese hacking group, “BlueDiskCFW” planned to release these custom firmware updates based on the LV0 keys and charge for them. To prevent BlueDiscCFW from profiting by selling their keys, The Three Muskateers released them.

“You can be sure that if it wouldn’t have been for this leak, this key would never have seen the light of day,” The Three Muskateers said in their statement. “Only the fear of our work being used by others to make money out of it has forced us to release this now.”

Here’s their entire statement with the keys censored (via PlayStation Lifestyle):
