Release: BwE PS4 NOR Statistics

Recommended Posts

Hello! Following my this program BwE PS4 NOR Statistics v1.00, another micro version of my PS4 NOR Validator, is designed solely to validate your NOR based on statistics only from Better Way Electronics!

Why make this you ask? Entropy and statistics are a well used methodology in the malware analysis field to determine if a binary file is encrypted, and by how much.

What is entropy? Entropy is a method for measuring uncertainty in a series of numbers or bytes. In technical terms, entropy measures the level of difficulty or the probability of independently predicting each number in the series.

What has this got to do with PS4s? Well the PS4's NOR is almost entirely encrypted and so with a collection of known valid NOR's it is possible to determine the level of entropy that represents a valid NOR and what level of entropy would represent a corrupt NOR.

When corruption occurs it will generally wipe out a large chuck of the NOR, cause the NOR to repeat itself or will fill the NOR with junk. All of this will decrease or severely increase the entropy.

Seeing as the PS4 firmware is likely to add more or less complexity with each update I have made available a settings file where you can adjust the predicted statistics.

Have fun! And yes this is made specifically for other PS4 repairers like myself. Maybe it will be useful for something else one day. Remember the fun we had with the PS3 NOR? :'(

NOTE: My program is designed for Windows 64 - If this is a problem then you're computing wrong.

Sorry for the copypasta! Enjoy either way!

Well my program was released for those who can't wait for my 12,000 line NOR validator. 

 

It's simple as it tells you with bright colours if your NOR is abnormal. A hex editor can't do that unless you already know what to look for. Not every one does. Hence the colours! 

 

I'll update it with a COREOS check and an additional corruption validation. 

 

Either way my main validator will arrive soon. I'm able to detect and fix corruption in CID that causes BLOD. So it's getting more accurate! 

 

Also I want COFFFEEEEEE
