PS3 CFW 4.82

I am trying to use my PS3 today and it seems that my son had accidentally upgrade the firmware to the latest Official Firmware 4.82. Prior to this I am having CFW 4.55 and I haven’t upgrade it cause all the games are still working. so ARRGGGHH!!!

Keep Calm and search google, so I stumble across some fine instruction to flash back the my PS3 CFW 4.82. I use the following link for the instruction

The exploit tools patch can be found in the following location.

To obtain the legit information after being con from few other various sites with firmware that was password protected and trying to get you to sign up for survey or something similar and selling your email address, mobile phone number and the like.

The Custom firmware should be obtained from the following.

REBUG_4.82.1_LITE_c5da00d59e4d1a7aa599e5d0e21415f8 _PS3UPDAT.PUP

I am patiently waiting for the exploit to work its magic, this is the second try and it still not successful.

After gazillion tries, the following steps is the one that is successful.

Use the HDD method instead of USB & follow each of these steps to the letter:

A) Flash NOR
It’s highly recommended to install the 4.82 official firmware twice on your console before using ps3xploit flash writer v2.0.
If your ps3 is already on ofw 4.82 then just install the 4.82 system update PUP again.

Once done, open your ps3 browser, set the homepage to http://ps3xploit.com/writer/index_nor_hdd.html
Restart the browser.
Follow the on screen instructions ie
1. download the flash_482.jpg file
2. initialize exploitation
3. patch flash

When patching is finished, you should get a success message.
To protect your console against any risk of bricking, do NOT turn off or reboot the console just yet, you should validate the Flash memory first.

B) Dump NOR
Now set your homepage to http://ps3xploit.com/dumper/index_nor_hdd.html
Restart your browser.
Follow the on screen instructions ie
1. download the dump.jpg file
2. initialize exploitation
3. dump nor flash

When the dump is done you should get a success message.

C) Validate NOR
Insert a fat32 USB key in ps3.
Go to the Photo colum on XMB, select the dump.jpg file & press the Triangle button. Choose to copy the file to USB device.
On PC, rename the file to dump.hex & use PyPS3checker tool to validate the dump.
You can get this tool from the dev’s github repo:
https://github.com/littlebalup/PyPS3tools
Read PyPS3checker_README.txt for tool requirements & usage syntax. You will need to install python 2.7.15, the installer is available for download on python.org.

In the PyPS3checker validation result screen, if you get either ros0 or ros1 valid with PS3Xploit 4.82 then the patch was successful, you can reboot & install the 4.82 cfw of your choosing. ;)
If the dump isn’t validated, ie you get more than 1 ros warning, do not switch off your console & post here to get further guidance.

Hope it helps.
