There are all kinds of PS3 CFW builds out there, but it's likely that none of them were made by you. This GUI by RedDot-3ND7355 and B7U3 C50SS allows you the luxury of being able to create and compile your very own custom firmware with the specialized patches you decide to activate. This most recent update makes great strides in improving stability, and adds in recent scene trends like 4.53 and Cobra patching.

Hey Everyone! Its me RedDot and im back with my team again to release you this new build of PS3MFW Builder 1.0.0!

We managed to find all the bugs about the repack/unpack/keys/tasks! Just follow them as respected and everything WILL be fine.

This is TRULY stable, and if you patch the right features you will NOT get brick/or whatsoever... I also recommend you have a minimum requirement of knowledge on modding :P

I hope the video helped A LOT. Credits to all the dev's that made this project possible and finished supposedly. But of course we will maybe continue to add features if new updates are released! So keep an eye on that updater.
