The only development I've heard of is one user claiming he got a diagnostic boot with SElinux permissive. (In the S9 root dev forum/thread) I also have a source who is NOT trying to be identified publicly because he works for google, but he informed me that "the android O build for SAMSUNG DEVICES, was developed with special instructions in it to automatically kick a KERNEL PANIC , if ANY app NOT on some internal White List attempts to access, modify, or send SU commands through any NOT LISTED app with those permissions granted already." ... now I'm not an Android level programmer, but I'm an old Linux dev/ penetration systems tester (lol) and from what I am gathering is that the patches or whatever that Samsung added to the O.S. also included an encrypted or hidden white list, which he says is VERY small, (as in number of items actually in the list) , but even he said they do not have any access nor knowledge of where they stored this. He did tell me that they delivered an incomplete or infant code for Samsung Snapdragon Model Note 8,9 and s8,9, and it was so crude that not only would it not compile because of missing crap Samsung deliberately did not supply them with... but he said that it was NOT lockable in that state, so Samsung either inserted their own locked kernel and whatever to create this B.S. broke down version of Android that is Root crippled. BUT the only clue he could give me was that "On no level can an E-fuse provide an unbreakable chain of trust, and that if an extreme modded were to actually break down the system board of an S9, they could in theory remove or add some sort of device that would bypass the Qualcomm Secure boot completely!" ... now this ain't a best friend or nothing so truthfully I'm surprised I got this much from him... but I've known who he was and that hes worked for Google nearly 12 years as a developer and software engineer. So I dont know if any of that info helps... but my contribution is that I can get my device (s9+ from Sprint USA Sm-g965U) replaced with little to no hassle, so I'm 100% willing to do any tests u need, providing that you give me at least a basic level of instruction, as to each set of commands or package u want me to flash. I'm pretty android savvy considering it's just a linux derivative... and I know Samsung 100% .. I've had every S - galaxy since day 1 . BUT throwing blind commands at my device that I have 0 understanding of their impact, makes me feel like a squirrel running across the freeway during rush hour! Plz Do me a favor and shoot me a private message and I'll give you my cell number and email so u can reach me quicker when you have something u need tested! Now please people don't berate me if something he said to me was not correct or you have different data to disprove what he said. I literally took notes by hand and had him confirm them, so I'm just the messenger/informant and u gotta realize that as a google employee, he #1 is partially not knowledgeable of ways to exploit the O.S. which is what the hackers come into play for. And make the developers work **** tons harder to FIX the hole the ****ed up in the 1st place! ? Lol... and #2. I did ask about the possibility of a $$$$ number he would take in order to provide an actual Eng-boot like that of the S8, and he said that "Those are developed by each individual corporation after they are provided the build source code", and that "google has no interest in possessing or archiving any such file because the O.S. does not need it to provide a developers version of the O.S., which is as far as Google goes in providing a new system to the companies.... so for something like that, reach out to one of the underpaid factories full of workers and I'm sure they would happily give you what you want for much cheaper than you imagine!" Ok that was very long winded but I wanted to cover all I could because I prob wont check this thread anymore.... plz PM me bro so I can get you my info ... and let's put this Flashing Guinea Pig (me) to work in getting this ***** at least hack rooted or maybe full!!!
