Most of you have heard the news of the PS3 slim downgrade on firmware 3.70, helping those buying newer or updated PS3 slim consoles to the scene. At the moment push aside “soft modding” and its time to bring on the good ole’ soldering iron back out.
This new method of downgrading basically requires the soldering of a multi-console-compatible chip known as ProgSkeet (or clone) which you can find or purchase HERE…or you can use Teensy++ board if you still have those from the good dongle days. A solder-less ProgSkeet is in the works, more info here.
Now the original tutorial was released in a very technical form and in Spanish, but we at PS3Hax have got you covered, and are bringing you easy to follow tutorial that a noob can follow on. This tutorial is long, but it is more detailed than complicated, making sure your bases are all covered.
So lets get started, this tutorial is split into multisteps. You should also check out the posts made here, and the posts that will be made in this thread to get assistance. The following tutorial was modified from the original Spanish translation by Dospiedras1973, and the tutorial/images were modified from PS3Hax member Mattr92 tutorial over at his site: RootedSystem and and thanks to the many PS3Hax members that brought us the proper/native translation of the original instructions .
