A $30 clip seemed like a reasonable price to pay to avoid spending a lot of time soldering. I used a NAND clip because the CECHA01's motherboard requires soldering directly onto the legs of both of the NAND chips. I decided to go with the Teensy because it appeared to be the most reliable, and least expensive flashing method for NAND consoles. For my CECHA01 I used a clip, and for my brother's CECH-2101A, I used alternate soldering. This can either be done using a clip, or through soldering directly to the chip, or by using alternate soldering points. To make the dump you will need to connect the flashing device to the firmware memory chip. 4.76 CUSTOM FIRMWARE PS3 INSTALLThe patched dump will allow you to install custom firmware through a USB device. 4.76 CUSTOM FIRMWARE PS3 PATCHIf they are you can patch the dump, and then write it to the console. A validation program is used to verify that your backup dumps are valid. In either case the custom firmware installation process involves making several backups of the firmware memory chip. You can read about other methods on the PS3 developer wiki. An E3 Flasher only works for NOR consoles, while the Teensy works with both NAND and NOR consoles. Two of the more popular methods involve using a Teensy++ 2.0 microcontroller, and using an E3 Flasher. There are many methods of installing custom firmware. In my case the CECHA01 fat has dual NAND chips, and the CECH-2101A slim has a single NOR chip. There are two types of firmware memory chips that are downgradable, dual NAND, and single NOR. Every fat system model number CECHAxx through CECHGxx use NAND chips, and the other downgradable systems use NOR chips. 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 that corresponds to your model number. In general all fat systems are downgradable, while most slims are, and no super slims are. Because 3.55 was the last exploitable system firmware version, all installation methods involve downgrading to 3.55 through flashing the firmware memory chip on the motherboard. To install custom firmware your PS3 needs to be downgradable to firmware version 3.55. 4.76 CUSTOM FIRMWARE PS3 MODI personally installed custom firmware primarily to be able to view system temperatures, so that I could mod my CECHA01 to run cooler, and to be able to play backups of my games. There are many more uses, those are just a few.
