What is bkpps3 bin ofw?
Bkpps3 bin ofw is a file name that stands for "backup PlayStation 3 binary original firmware". It is a file that contains the original firmware data of your PS3's NOR chip, which is the memory chip that stores the system software and settings of your console. By backing up this file, you can restore your PS3 to its original state in case something goes wrong during the downgrade process.
How to obtain bkpps3 bin ofw?
To obtain bkpps3 bin ofw, you need to have an E3 flasher device, which is a hardware tool that can read and write data to your PS3's NOR chip. You also need to have a compatible PS3 model that can be downgraded to a lower firmware version. You can check your PS3's minimum firmware [here].
Once you have the E3 flasher device and the compatible PS3 model, you need to install the E3 flasher on your PS3 following [this guide]. After installing the E3 flasher, you need to make some backup dumps of your PS3's NOR chip using an SD card. You can follow [this tutorial] for detailed instructions on how to make backup dumps. One of the backup dumps will be named bkpps3.bin, which is the file you need.
How to use bkpps3 bin ofw?
To use bkpps3 bin ofw, you need to patch it with a program called PS3 Flash Auto Patcher, which can modify the file to allow you to downgrade your PS3 to any custom firmware (CFW) or any original firmware (OFW) 3.55 or lower. You can download the program [here].
After downloading the program, you need to put your bkpps3.bin in the PS3_Flash_Auto_Patcher_v4.46 folder. Drag and drop the bkpps3.bin onto ps3_flash_auto_patcher_v4.46.exe; The program will open and wait for it to apply the patches. Now there will be a new file named bkpps3_NOR_patched.bin. Delete all files from your SD card and put the bkpps3_NOR_patched.bin on it, renamed to bkpps3.bin.
Now you are ready to downgrade your PS3 using the patched file. You can choose between two methods: noFSM method or FSM method. The noFSM method does not require a factory service mode (FSM) dongle and does not format your hard drive, while the FSM method requires an FSM dongle and will format your hard drive. You can follow [this tutorial] for detailed instructions on how to downgrade using either method.
Bkpps3 bin ofw is a file that contains the original firmware data of your PS3's NOR chip. You can use it with an E3 flasher device and a PS3 Flash Auto Patcher program to downgrade your PS3 to any CFW or any OFW 3.55 or lower. However, you need to be careful when performing this process, as it may brick your console if done incorrectly. Always make sure you have multiple valid backup dumps before proceeding, and never downgrade to a firmware lower than what came on your PS3 when you bought it new.
