==== BwE PS4 NOR Validator ====
==== BwE PS4 NOR Validator ====
[[File:Screenshot norvalidator2.png|300px|thumb|left|Results]]
[[File:Screenshot norvalidator2.png|300px|thumb|left|Results]]
Developed by [[User:BwE]] this application is designed to validate the entire NOR flash of the PS4.
It will check every byte of the flash and read approximately 1800 specific offsets.
Areas that can be repaired easily are labeled as static, meaning it will be the same across all consoles.
Dynamic areas are interchanging either with each firmware revision, the console itself or the model of console.
PerConsole areas (such as the majority of the CID) are unable to be modified.


This program is the release version of [[User:BwE]]'s PS4 NOR Validator, it is designed solely to validate the NOR flash of your PS4 console!
Alternative validations are based on known corruption patterns or expectations. This will be improved with each revision.
MD5 validations are based on known valid consoles (or file sizes) and this is why entropy and the above validation are added as supplementation.


Why would you need to do this? Well if your console has suddenly died and has what is called the 'BLOD', the NOR can be the reason why. Using my program will allow you to validate literally every single byte of the NOR (or over 2100 specific areas) - allowing you to see where or if it is corrupted.
There are various table based validations, which are based on accumulated data from various consoles, these will be improved constantly.


The most common area of corruption that causes the BLOD is the CID. Some areas of this section can actually be repaired, if you're lucky! I and others have done this! Don't forget to use my Comparator tool to help you understand what the difference is for a specific section of the NOR. It will help you with patching!
Other validations can use regular expressions which are again, based on accumulated data.


Other areas can be inter-changed between different consoles and are more suited for repair, the WiFi/BT module is a good example of this.
The ambiguity of consoles leads to the usefulness of the WARNING result. If it does not pass the expected result and it does not appear explicitly corrupt it will present a warning. Some areas in the NOR are so extremely dynamic that maybe one in 50 consoles will have it, and for the life of me, I don't know why.


So fundamentally, this program is for console repairers like myself. If you are indeed a repairer and run a business I can make a custom 'bulk' version for you! But for now, feel free to put multiple *.bin files in the working directory as my program will provide a selection menu.
My suggestion is to use this program with a cognizance of the ENTIRETY of the results. If for example the flash presents a low entropy and various warnings throughout, this is a bad sign. If the console has perfect entropy but a large (0x1000) corrupted area then I would also see this as a very bad sign. If there are a few danger results in the filler data, I would not worry too much.


I am also happy to give advice on your NOR or help interpret your results, just post on the forum or give me an email. If you can bypass my filter, send me a link to your NOR!
Eventually this program will be more and more reliable. Use it, report your results and help develop it!


If you encounter any errors or weird results - or better yet if your NOR is labled danger in any areas, but still runs fine - let me know!
The program also features extraction of the NOR, byte reversal and statistics.<br>
As of 1.1 it does not support Dev/Test consoles, but will in the future (most of the code is already in the program).


Keep in mind the CoreOS and other large encrypted areas could still be corrupt regardless of the results (I cant check every byte in an encrypted section, hence alt validations). This program is NOT perfect, but it is WAY better than just using a hex editor or never truely knowing if your BLOD is caused by the NOR!

==== BwE PS4 WiFi/BT Patcher & Extractor ====
[[File:Screenshot2.png|300px|thumb|left|WiFi/BT Results]]
Developed by [[User:BwE]] this application is designed to validate, patch and or extract the [[Flash-Main#0x144000|WiFi/BT Module]] of the PS4. The reason for this is illustrated in [[Software_Wireless_BT#BwE_PS4_WiFi.2FBT_Patcher_.26_Extractor|this page on the wiki]]. It will use MD5, entropy and pattern analysis to determine if and where the module is corrupted. From here it will determine a valid replacement based on the console's expected module version and size. Should there be no matching version available the program will offer you the ability to patch a new header and new module. This methodology is risky, but if this is your only option then it is worth a try.

As of version 1.5.5 there is an ability to upload dumps directly to me. I use these to improve the program and validations.
==== BwE PS4 NOR Statistics ====
Abusing this service will result in your ban from future use of my validator.
[[File:Mainprogram.png|300px|thumb|left|Statistics Results]]
This program, another micro version of [[User:BwE]]'s PS4 NOR Validator, is designed solely to validate your NOR based on statistics only!<br>
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.<br>


''Regarding Anti-Virus:''
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.<br>


I protect my program with Themida. The problem with this is that heuristically some AV software see it as a threat.
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.<br>
This is because people who make or redistribute old malware also use Themida to help make themselves undetected.
 
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.<br>
 
Seeing as the PS4 firmware is likely to add more or less complexity with each update I have made avaliable a settings file where you can adjust the predicted statistics.<br>


Ultimately, it is up to you to trust the program and me. I encourage you to upload to a sandbox to see for yourself.
