Step 1: Preparing the Teensy and PS3 motherboard for a NOR dump The Teensy I bought from AliExpress came with the voltage regulator. This is also how the PS3's NOR chip will be powered when dumping the NOR. To use the Teensy you need to follow the 3.3V Teensy conversion guide. With the patched firmware you will be able to install the custom firmware using a custom firmware update file. This involves dumping the NOR firmware chip, patching the firmware dump, and then flashing the patched firmware file. Running anything after firmware 3.55 means you will need to patch your system. All you need to do is upgrade your console to firmware 3.55, and then install the custom firmware as an update file. If your console is running firmware 3.55 or earlier already, then you can ignore most of this guide and skip down to step five. Now that you are familiar with PS3 custom firmware, I can give you an overview on how it is installed, and provide you with a list of things you'll need. Custom firmware installation process overview, and what you'll need You can find the model number on the sticker on the back of your system., it should begin in CECH. There is a more detailed list on the PS3 developer wiki, look at the downgradable min praxis column (needs to be 3.55 or lower for custom firmware) that corresponds to your model number. Sony patched this issue in the next firmware release, and nothing released since has been hacked.īecause of the 3.55 firmware requirement not all PS3 consoles can run custom firmware. In general all fat systems are downgradable, while most slims are, and no super slims are. This is because the encryption system on version 3.55 was cracked, allowing custom firmware updates to be seen as official software updates on consoles. Monitor temperatures, and control fan speeds.Ĭustom firmware installation requires a system that is running firmware 3.55 or earlier.With custom firmware a PS3 can do many things, including: This section is a brief overview of the custom firmware background information I wrote about in my last PS3 custom firmware post. Custom firmware allows the PS3 to run homebrew software. What is custom firmware, what is it used for, and what are the installation requirements This post goes into more detail on the same custom firmware installation process with a CECH-2001A PS3 slim console. In March I wrote a post about installing custom firmware onto a CECHA01 PS3 fat, and a CECH-2101A PS3 slim.
