Hello! After my BwE PS4 WiFi / BT Patcher & Extractor this program BwE PS4 NOR Statistics v1.00 followed by Version 1.1, 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.

And from the README.md: BwE PS4 NOR Statistics Standalone

This program is a standalone statistics generator for the PS4 NOR chip. It will output known expected results based on comparative analysis of valid firmwares. The program also is compatible with an external settings file for fine tuning the valid statistical results.

Also for those who enjoy a trip down memory lane, here's blast from the past via HackADay.com on how the original Sony PlayStation was hacked. (y)

If you like what I do, or just like me for me, buy me a coffeeeee!

Lol the program isn't all that special. I just felt I had to release something given that I have had a delay on the actual validator. But thanks :)

I think I've said it before: I enjoy making the cracktro and artwork more than the programming hehe

I forgot to add these to the original post:

This is a valid NOR:


This is an invalid NOR:


See! Statistics! Fun!
