Homebrew developer Hellcat has released an update to his application, Recovery Flasher, bringing it up to v1.30. Recovery Flasher is basically a utility that can be used to recover from semi-bricks and install 3.71 or 4.01 M33 firmware, all without the need of Pandora.
One of the most notable newly added feature to this update is the extended functionality of the backup/restore options. Which means you could flash a backup of a complete firmware onto another PSP regardless of what that PSP's current firmware is. More info in the changelog found below.
Here's the full changelog for v.130:
As always, you can find the download below. Make sure to check out the readme file, for installation info and other notes. Enjoy!
