Ever seen a room full of developers get this excited before? - AT&T Samsung Galaxy S 5

EDIT: Let's let the dev's have their fun without a bunch of newbs poking in on them. Sorry, devs.
Probably don't want this info to get out to the entire Internets anyways.

Pretty exciting. I am not a dev. so I dont really know how to distinguish between what exactly is going on, but a little progress and excitement is always good for the community. Not to mention the respect and bounty these devs will get once something major actually does happen.

Basically, evilpotatoman located a much-wanted Qualcomm tool that could possibly lead to finally unlocking the bootloader of S4, S5 and Note 3 (and others). *Possibly being the key word.
At the moment it's still not possible, but the tool apparently gives them a huge leap forward in development towards this goal.
They've been looking for something like this for a few years now I believe.
I'm not a dev, don't pretend to be one. The extent of my "development" is writing a few scripts. lol. So remember that I may be misunderstanding some things here. :good:
There are a bunch of files attached to the thread.
But none of us should bother downloading them because you have to be an ultra-dev to know how to use them.

My understanding i that this is the SDK for the SoC on the S5 and other phones. It includes a qualcomm dev signing cert but I'm almost 100% certain that no production phone from AT&T will accept BL's signed by the qc dev cert (or someone would have used it to sign one of the unlocked BL's by now plus if that were the case my guess is qc would be freaking out and sending takedown notices by now). So basically if Samsung or AT&T were to provide the signing key or somehow we were to brute force it(very unlikely) we would now be able to easily sign packages for the phone. So while helpful, without the signing keys it doesn't really do anything except provide more insight into how the whole secure boot process works.

NEW approach to rooting Perfect SPLs etc

hi all
my theory is this but i ask all of you first if this has already been tried, With OTA updates these are all signed with i imagine official OTA keys so your device will install the update no matter what.
Now my question is, is there any way of reverse engineering the OTA signed zip files to figure out what these keys are so that we can make a ROM that will enable root on devices with Perfect SPLs
all information is appreciated
Thank you
If you have any place for me to download the T-Mobile OTA updates I'd be happy to look at them for you
Im not a proggrammer or lwayer, so take my word with a pinch of salt. Wouldnt this need reverse engineering? Making this whole deal illegal?

This. We need T-Mobile's private keys to sign the update, which won't be happening. If you can "reverse engineer" that then get ready to be famous, cause you just broke modern cryptography.

Depends on what country you live in. In the US, probably. In most other countries....probably not.
Those who know little about serious cryptography often assume that a particular encryption method is safe if nobody has cracked it. However, as the eminent cryptographer Bruce Schneier pointed out in his Crypto-Gram Newsletter dated 15 February 2003, "That's actually backwards. In the world of cryptography, we assume something is broken until we have evidence to the contrary." By this he means that an encryption method can be fully trusted only if it has been subject to rigorous and critical analysis by experts to check its resistance to all known cryptanalytic attacks.
While it is true that it's pretty much impossible to crack it, you can delete the keys and make your own. Although, I'm not exactly sure this is what he is looking for...
its encrypted, although you have a public key, you cant change a update since it breaks the signature... you also cant sign an update since you dont have the private keys... basically, no.
It depends on the strength of the encryption if it is AES-128 good luck you ain't never cracking it. If its RSA-512 It could be cracked by 1 person in 2 months. Or by a team of people say using boinc in 2 days. We cracked all the OS signing keys for the Entire line of Texas Instrument Graphing Calculators got a DMCA take down as well. We got EFF lawyers working to make sure we can keep working.

Isnt it illegal though to be cracking this stuff?
Not saying you would get caught but if you did you may or may not be charged.
But its easy to root so why try another approach?
What would make it illegal?
YOU own the equipment.
The modifications you do to your equipment do NOT enable you to break the law and DEFINITELY do not MAKE you do illegal things.
wow thanks for everyones replies, the only reason i question is for all the new android devices come with perfected SPLs which either conquer or make it very hard to gain root, so my theory was if we could get these keys we could make Roms signed by 'android' which would contain modified SPLs and recoverys
A will a way..
With modern encryption ..there are very few people who understand it..IT CAN BE BROKEN. NOw if u want to read about a sort of physical encryption check out quantum cryptograpy.

It's still a terrible idea. You'll make T-Mo very, very angry at both you and XDA, with almost zero real gain. The rooting process is trivial, and it works. I'd also recommend talking to a lawyer if you really intend to proceed.
its only for personal gain 'wink wink' i can do what i want with my own device as long as i do not distribute it intentionally
Actually, so long as you don't distribute any code or products themselves considered proprietary to T-Mobile, if you reverse-engineer their encryption key, there's nothing they can legally do about it.
What I mean by the above is that if we treat the decryption process in a manner similar to how Cyanogen does his current ROMs, and stick to simply releasing OSS-derived code, there's really nothing that T-Mo or anyone else can do 'bout it. The trouble with this is that it would require somehow maintaining the drivers for the SPLs on the device while only modifying the portions that lead to root.

What is an Encypted Bootloader and What does it Mean?

We seem to have a lot of confusion in the Atrix forum about the implications of an encrypted and or locked bootloader.
What is a bootloader?
See this article for a decent description.
Is the bootloader on the Atrix encrypted?
We don't know and likely will not know until the phone is released and people smarter than I can look at it. No reviews, including the Engadget review, have looked at whether the bootloader is encrypted. However, some have inaccurately said that it is because the installation of non-market apps is not permitted the bootloader is encrypted. However, this is a separate issue and is a requirement imposed by ATT that has nothing to do with the bootloader.
Why do people assume the bootloader is encypted?
Motorola has a strong recent history of releasing encrypted bootloaders, see the Droid X and Milestone phones. Most of the current discussion about the bootloader is limited to what we have seen from Motorola in the past. That being said, there is some hope that the bootloader will not be encrypted. In prior phones, such as the Droid X and Milestone, Motorola relied on the eFuse feature of Texas Instruments OMAP processors. Given that the Atrix uses an Nvidia Tegra 2 chip it is unlikely that Motorola can utilize the same eFuse technology.
As a result, there is some reason to be optimistic that the Atrix will only have a locked and not encrypted bootloader.
What is the difference between a locked and encrypted bootloader?
This is a good post on the topic. Locked bootloaders are on almost all android phones, including the Nexus S. Although certain locks, such as the Nexus S, are easier to open. A locked bootloader is essentially software that is written in such a way so as to prevent you from gaining access. So far XDA devs have been very skilled at cracking locked bootloaders by finding holes in this software.
An encrypted bootloader, from my understanding, is not itself encrypted, but signed by an encryption key. The phones hardware will refuse to boot unless the software that it attempts to boot is signed with the correct encryption key. The only options to crack this protection appear to be to go around the bootloader which is unlikely or to crack the encryption which also appears unlikely. See this post for more discussion.
What does an encypted bootloader mean to me?
This post at Android Forums provides a great summary of the effects of an encrypted bootloader. If you have the time, the entire thread is very informative.
The bad news is an encrypted bootloader likely means no custom kernels. This means that custom ROMs must rely on the official kernel. It also means the OS version (Froyo, Gingerbread . . .) is limited to whatever the official release is. The good news is that root access is still be possible. Root access allows you to run certain applications as the root or administrator. This allows for a lot of customization and hacking of your phone.
In the end, an encrypted bootloader may hinder your ability to completely hack the phone.
Can an encrypted bootloader be cracked?
Unlikely. For a brief discussion see this post and read the thread for a better understanding. I am aware that there is a team working on cracking the Milestone encryption using the BIONIC platform and a distributed computing effort, see androinc.net. However, even that team admits that the second coming of the dinosaurs may occur before they crack the encryption. I believe on the Milestone that the encryption is 1024 bit, which according to androinc.net may take hundreds of thousands of years to crack using a brute force method, even on a distributed computing platform.
Can a locked bootloader be cracked?
We won't know until we see it, but likely yes. Generally all software coded by humans has some error in it that can be exploited.
Why should I care if the bootloader protection cannot be circumvented?
You don't have to. But, in today's environment, consumers are tied to a 2 year contracts but new phones are released on a 1 year or less timeline. This means the device you buy today will likely be forgotten by your carrier and the phone manufacturer long before your contract is up. The inability to load custom kernels means that consumers cannot upgrade their own phones after the manufacturer decides to no longer support the phone. The decision to stop supporting upgrades often occurs well before a phones 2 year birthday, see the Motorola Upgrade Roadmap.
In addition, many people believe that they have purchased the phone hardware and should be permitted to do anything that they please with the hardware.

thanks for writing this i was going to my self today as i have been fighting people all day with this, i was trying to get motorola to tell me as i had a few reps available in a forum and one said that he will get back to me shortly with an answer ... but i was having to do so with people that dont know the difference chiming in and making the q&a with moto hard even for some one who does know what hes talking about ... any how i will update when i get my reply, and thanks again for putting info in right place btw up at top you put milestone instead of atrix

+1 here, very informative.
Thanks and sorry about the typos.
Nice job both in the layout and in maintaining an unbiased take on the possibilities.
thankyou for explaining that so well
can we get a MOD to sticky this for a while, at least until we know whether it is encrypted or what not. could really cut down on the "does the bootloader restrict me from doing xxxxxxxxxxx?" chatter on all the threads.
+1 Great post! Guess we'll have to wait for quantum computers before we can crack 1024bit encryption in under a lifetime (seconds probably.) But very informative, I'm off to read everything you linked in your post.
Excellent post sir!

I saw both of those. I am not totally convinced by a PR response, even if it is from Moto. So far the devs here in XDA seem to think it is only signed. I am inclined to believe them more, at least until I see otherwise.

Signature Checks on Boot

Just so everyone is aware, the kernel and the recovery partition signatures are checked on each boot, changing those will leave you with a brick, until we have proper firmware to recovery with.
I found out the hard way.
On my second Atrix now.
Casualty of war
Taking one for the team
Well that sucks..
any free partitions that we can "steal"? and basically pull a haret where it loads partially from legit bootloader and kernel, then shuffles off to a different partition we CAN write for the real kernel, unloads all that other stuff and then launches the new kernel partiion we've modified?

I guess that when we told you this, you just had to find out for yourself. The recovery should only be checked when you attempt to access it, but the kernel is checked on every boot. I hope you did not return to store as defective.
DG, thank you for putting yourself out there, and putting together roms along with the dev work.
Its nice to see some progress being done along side all the people on here saying what we shouldnt be doing/trying with our phones.

What is being elitist by my statement? That before you started playing with your shiny new toy, we advised that doing certain things with your phone without proper firmware to restore your phone, WOULD result in a "soft brick".
I do not have a motorola ATRIX, never said I did, but I can read the firmware pretty well. If your offended by my post I assume it is because offered up my standard line of "hope you did not return it as defective", because nothing else in that statement should lead you behave like a child.
Here how about this for a Facts, my rom was the first to safely remove Blur from the Droid series of phones safely, after reading the firmware from your phone, and your deodexed version of the firmware there are many portions you could remove safely.
If you have questions you could ask and get the answers, but as it stands right now, we are just trying to help you save yourselves. Many people will enter these forums, and while each person is responsible for their own device, they will try to follow what you have done and they too will soft brick their phone. I'm not sure of your ethical and moral makeup but too many people return their manipulated device to the provider as defective causing every to pay for their mistake.
I just hope you bought another Atrix outright and did not scam ATT/Motorola.

DesignGears,
Please don't let a claim-to-know-it-all self-righteous Prick like jimmydafish discourage your efforts.
As far as I'm concerned (and probably the majority of people who mash the refresh button on this subforum multiple times a day would agree) it's people like you (people who have actively contributed to the users here at XDA in the past (all your captivate work)), that make me feel lucky to own the same type of device that you and other dedicated devs like yourself own.
Its hard to imagine how someone who probably played a very small part on a team -- a team that, as far as I can tell, has never managed to actually produce any real results on the DX -- can know so much about a device he doesn't even own.
And if reading this post encourages members of any such team to get their panties in a wad and start talking about how they are not going to contribute here now, well then to that I say: good riddance. For every one small tip you may provide it seams like you offer two holier-than-thou-doughe-bag-comments that frankly this section of this forum could do without.
But again, thank you DesginGears and Devs like you

Maybe if more people softbricked and returned phones that have locked down bootloaders, oems and carriers might finally realize that when someone buys a piece of technology, they own it, and would like to use it as such.
That includes:
1. Not having some POS skin on top of stock android (Blur)
2. Not being locked into paying twice for the data we already pay for (tethering)
3. Not being allowed to easily install non-market apps that we develop without jumping through hoops (slide loading)
4. Not having to wait for the carrier or oem mfg to release an update before we can have a current version of Android.
Call it a Brick-n-Return Protest

[TOOL][CyboLabs] Open Bump! Sign your boot images by yourself!

CyboLabs is Proud to present
Open Bump!​
What is Open Bump?
Open Bump is a recreation of the closed source Bump project run by Codefire.
It will allow you to "sign" your boot images in the same way that Codefire does it, only you don't need an internet connection.
Click to expand...
Click to collapse
What Open Bump is NOT
lets get the obvious out the way. It won't axe murder you.
It is not a direct reverse engineer of Codefire's implementation. I found the key and iv on my own
The magic bytes were taken from Codefire's method however. If anyone has insight has to how they were found, please shout up.
It does NOT take your private data so you can use it. Tin hatters feel free to double check
Click to expand...
Click to collapse
How did I find this out
I had a general idea of what to look for, having heard that the exploit is related uicc, and is signed with a cipher.
Dropping the aboot image in to Ghex led me to finding a reference to "uiccsecurity". Using the bytes around this, I found a repeat of 32 bytes, which was followed by 16 bytes which formed something that resembled "SecureWallpaper".
As you can probably guess, this was mainly trail and error backed by common sense and logical thinking.
you can programmatically find these values with the python script:
Python:
aboot_name = './aboot.img'
aboot = open(aboot_name, 'rb').read()
key_end = aboot.index('uicc')
key_start = key_end - 32
key = aboot[key_start:key_end]
sec_key_start = aboot.index(key, key_end)
iv_start = sec_key_start + 32
iv_end = iv_start + 16
iv = aboot[iv_start:iv_end]
deciphering some already generated "signatures" proved that these were the key and iv used for "signing" the images.
Click to expand...
Click to collapse
What is coming next?
Inspecting the signatures that were originally uploaded and the ones that people can generate now, I found only one pattern.
The only similarities were the first 16 bytes of each "signature". I believe that only the magic number is needed, and none of the garbage that follows. This has been confirmed by the LG G3 dev from CyanogenMod, Invisiblek Done

How to use it?
I don't know how well this will run on anything other than linux, so for now.. I won't talk about it.
First, ensure you are using python2
then run the script
Code:
python2 open_bump.py "/path/to/boot.img"
flash the output, and enjoy

Thanks to:
Obviously, this wouldn't have been possible without Codefire since I wouldn't have known where to look, or that it was exploitable. And it was them that found the magic key.
Big thank you to @pulser_g2, who offered invaluable input on cryptography
Big thank you to @invisiblek, who I mercilessly kanged the main part of the image padding script from

The original part of finding this information out was done on my own with guidance from pulser. The final results of this are posted above.

Thanks, thats great news to have an open source tool here!
Do you see any chance that this could be integrated into CWM/TWRP so that the recovery rom could bump the boot/recovery images before flashing?
Because the boot/recovery.img has to be extracted from the ROM-zip before flashing, bumping it here would make sure that the phone can boot the image even with the newer bootloader.
This would be great for rom-devs since they don't have to change anything and it would even bump roms that are not maintained anymore.

simple answer, this can be added to the build step really easily. See this commit
edit:
of course it may be useful to make a c program to do this.... I shall think on it.
Propably stupid question but i ll give a shot. Since we have the magic key we cant just skip the bump stuff totally? As i can understand, i dont wait official developer team join the bump train, thats why the damn development of the device is really back while the hardware is more than capable.
**To the OP i wish i could give you a thousand likes sir!
After getting the bootloader may be open G3؟؟
Why not use the original Bump?
Quote:
Codefire has been extremely vague about their method, obviously to prevent someone else replicating their results.
They are also storing people's data unnecessarily, and even adding some information relating to the user in to the "signature", possibly for tracking purposes.
As a result of it being an external service, many reputable teams (which won't be named unless they want to be) have said they will not use it, and would rather wait till LG releases the official unlock method.
Finally, Codefire have said the sha1sum of the boot image is required. Whether they knew or not, it is NOT required, and I will be changing this tool to compensate for that.

Happy you found a new exploit for us builders and devs, just feel like you kinda disrespected codefire team by accusing them of things before actually talking to them, seems a bit counter productive, this may piss them off and next device you can kiss new exploits by them good-bye,
just my 2 cents on the matter,
i'd remove the line...
in any case thank you very much, i will add it to my build script

Propably stupid question but i ll give a shot. Since we have the magic key we cant just skip the bump stuff totally? As i can understand, i dont wait official developer team join the bump train, thats why the damn development of the device is really back while the hardware is more than capable.
**To the OP i wish i could give you a thousand likes sir!

"Bump stuff" has nothing to do with users, the devs and builders do the "bumping", and development of the G series has nothing to do with bumping, it just takes time to bring everything up
Good job cybojenix. (moderator edit: watch your language please)
Way to ruin a good thing.
I'm done with Android now. You can do it all now - since you obviously know better than me and everyone else.
I don't appreciate people trying to blackmail me - EnderBlue and Cybo both.
Don't believe me? http://hastebin.com/gulumezawi.txt
Good job guys. Way to ruin unlocks for all future LG phones.
If I *EVER* decide to come back, I will not be releasing anything as free or open source. You've sullied my impression of the open source community. Anything I do will be private releases from now on.
LG hadn't patched Bump, and they were going to leave it alone for us as long as we kept it as a service.
Well, looks like that's over and done with.
Bump included a hash of the image that you uploaded and a hash of your developer ID, and some random junk bytes. That's all. It's exactly what we said it was doing.
Well, hey, now you're free to take over and write roots and unlocks for all LG phones since you obviously have the talent to do so.
Let's be honest though, without my team's hard work that you stole, you wouldn't have been able to do any of this.
But you knew that, you're just a bottom feeder.
I don't get angry often at all- but congrats! You've succeeded in making me mad! Achievement unlocked!
I'm done. Your turn.
EDIT: Also, you know you can't open source your project either considering it contains 'stolen' LG crypto keys. https://github.com/CyboLabs/Open_Bump/issues/1
Have fun with that one.

First off, I didn't black mail. I gave your team notice about open sourcing it after reverse engineering the LG bootloader, not your "signatures".
It's your choice if you want to leave Android. Pinning the blame on me is somewhat childish though.
LG not patching Bump? That's a ludicrous statement, and even if it's true, it's good that this script got released. That way they know it should be patched, since having it a service clearly makes all the difference to them.
The hardest part of your teams work was getting the keys. If you know where to look, then it's easy enough to get engineering builds which I suspect contain the master magic bytes which you released.
I'm honestly shocked at your reaction though. I gave your team all the credit and stated which parts I did myself. The part about the service, and the deception was justified.
You tried to obscure something which by logic can't be obscured. That's how so many people realised they can just append the bytes to the image.
So which one would you rather have, LG not patching the exploit (as you so claim), and having an unknown number of people in china running around flashing custom boot images, or have everyone know how to do it to force LG to recheck their security measures.
What I did may not have been fantastic for the community, but what you did was insanely dangerous for the 90% of LG users.
All you did was make it so LG locks down the bootloader. And really 90% of users??? There probably isn't even 3 percent of the LG base on this website. All you did was screw everybody else over so you could have YOUR OFFICIAL CM.
As well people saying you didn't do enough and are still using there signing key as well as attacking it as well.
Way to think about yourself. You didn't care about the 90% or you wouldn't have done this.
I personally hope LG locks down the bootloader now. Go the way Samsung did and put an efuse on it and prevent downgrading. Hopefully all this happens with lollipop so you can screw over the rest of the LG crowd.

"Hey let's potentially close all future LG unlocks and thus the chance to use CyanogenMod on future LG devices then. Just so I can get the current CM builds to say 'Official' and get a big pat on the back from the CM dudes who probably don't care about me too much."
Is that what went through your mind? That instant gratification and ignorance really shows who you are because that's exactly what I see from this OP of yours. Enjoy your 15 minutes of fame. You probably just killed a chance for years of it.

Yes, because I've been such a massive supporter of cm. (sarcasm in case you didn't realise).
I started reverse engineering the bootloader for research purposes. If it was more complex than what I have said above, then I probably wouldn't have done this thread.
If it weren't for the fact that the magic stays the same across all signatures, then I also wouldn't have done this thread.
The response I got from them when I contacted them before releasing this was pretty much one of lack of care. So I went ahead and posted it.
I couldn't care less about fame. In fact there isn't really a lot I do care about, but I won't have the community alienated in to thinking the codefire service was such a great thing.
And once again, I refuse to take the blame for their team leaving Android.

Fair enough, 3% are here, so this benefits the security of 97% of lg uses, if the claim that lg was alright with it running s a service is true.

I saw your PM to autoprime in IRC, it was "I am going to post what I found or you do, either way its going there", it wasn't lack of care, it was that you just stated a fact and left, it was a very rude unthoughtful thing to do, also don't try to BS everyone with your research, you and about 100 other people found the "magic keys", the problem is those "magic keys" were placed there by team codefire, you didn't find them, you found that they were using the key and copied their work, anything else you say is a lie, at least the other 99 people who found this had the basic respect to not post it unless the original team allowed it.
There was no reason to post this, their site was working fine, and if you used the API there was no problem of tracking since it just uses a UID to identify to the server.
at least admit you were wrong and say you are sorry, they won't fix anything but will gain you a minimum amount of respect

Wrong, I stated that I was going to open source it, meaning the work of put in to getting the key and how it's used to get the original magic.
It was after that that I realised the final magic is the only thing needed. I actually worked out how to get the magic key a few hours ago, but since I don't have the right images, it won't be globally usable.
Fair enough, I apologise for pointing out the flaws in codefires service, and that they took it badly.

Enderblue-"well, would you be willing to open source it so we can have a official cm support?"

It isn't like it matters if you are or not. It says right in the chat he doesn't want it open sourced. I'm sure about 99% of the people on here have seen that already and I'm pretty sure you have seen it as well.

but the chat wasn't with me, so your point is null
autoprime had ample opportunity to say "don't do it yet", or "go talk to IO". but no, no objections were made.
Codefire treated the service like any other company would treat their unlocking service, so I treated them like a company and showed how it was done.

(No progress yet)Root dev for Galaxy S9 Plus SM-G965U (Snapdragon)

Do not ask for an ETA
Once the mods start getting onto people for asking, I'll take my dev work off site. I don't want to upset mods and admin over people being impatient.
I've been looking and root isn't available yet for the Snapdragon version. I've created root access for a few devices so far, be it years ago. I want root, so I've decided to start dev work on my own. Can't say how long it will take, or if I will be able to, but anyone that is willing to test or help, feel free to comment and say so, since help would be greatly appreciated. Testers are needed.
First off though, what advancements have been made so far? Several posts I've seen have dead links to data, so to start, I'll need to know what's been done already. No need to reproduce failed outcomes.
Reserved for future links.

One guy flashed a combination version of the firmware and got the OEM unlock toggle to show on a SM-G960U. It switched on and off but I am not sure if it actually unlocked the bootloader or not. There is a TWRP already ported to the Snapdragon version as well, although only for the Chinese and Hong Kong version, it should work on our device if you can get the bootloader unlocked first. I have been scouring online and in the forums since the phone came out and that's all I nave found thus far. Im sure you already know these things, but I figured I would say it just in case you weren't aware. Hope you get it figured out! Good luck! ?
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!!!
Hello, i've just finished reading all above and from what I've read I can tell that not all hopes are lost as well I'm offering my help to be a (TESTER) for any attempts you wanna try, however, please note that I'm NO DEV just a user who would like to his phone rooted ASAP that's all, so please explain the commands that you would give me and the steps. plz PM me so I can get you my contact info
It ain't happening with the known exploits.
Ok, so far I have a few routes I plan to take that have worked on other devices. Working on the first, but not at the moment. The rude comment compelled me to post my own. Devs don't follow old ways of doing things so get that out of your head if you want to think forward, not backwards. I have found what could be an exploit in the rom itself that "might" be the starting point to get root access. This is NOT an ETA but hopefully we can start testing in the next few weeks.
I'll say it now, don't get overly excited a possible exploit has been found. I make no guarantee on it being THE exploit needed. Just be patient, and if you have insight on a way to attack this or another possible exploit, do say so.
If anyone knows of the bootloader partition already having been copied, post a link. I share mine at the moment so I don't always have it around, so any of the bootloader data would help greatly.

Myself and a handful of other people involved in us snapdragon s8/s8+/n8+ took a brief crack at it a little while ago to no avail. I don't want to go into too many details on here as 1) Samsung is watching surely and 2) the contents from the peanut gallery get old quick but here are the cliff notes. Feel free to pm me here or on telegram for more details. (Backstory on me, I created samfail which was the first/only n8 root method and the second for the s8/s8+ and the only published one beyond bootloader v1.
- samfail is 100% patched. No known way to modify system
- you can't mix combo boot with stock images anymore. Samsung got wise to that. Figured out how to track it if we can force write a system image
- there is a ton of new system level security because they had to move out of the boot image due to treble. Probably the first big nail in the coffin I'm.
- don't waste your time on the oem unlock toggle in the combo/factory rom. No it doesn't unlock the bootloader. The us snapdragons don't respect it's value outside of turning off frp, but that was with the s8 idk if it is still true on the s9.
- the other poster is right about the anti root thing. It's in the open source kernel code. If anything being exexuted under uid 0 matches a list of common/known root mods/not stuff that is supposed to be there, instant kernel panic. Things like "binary is called BusyBox" are on that list.
This was the point I gave up. Partially because I don't have the device so testing is extremely difficult (I wised up this year and purchased a intl. Snapdragon sm-g9650 which has full oem unlock just like the exy).
In sure there's things in forgetting right now and again, being too transparent here results in root method bring patched faster, hit me up if you want more brain dump

Although I have seen a lot worse on these threads, his comment was pretty negative, which is what we do not need in this thread. I wish people would just keep their thoughts to themselves if they have nothing to add to the discussion. I also will test so let me know if there is anything I can do to help.
i also have a g965u and have been trying various mwthods to no avail at this point.. we need new exploits to be found.. all the obvious stuff will not work

You cannot buy Exynos from a carrier. You have to buy directly from Samsung for that. I know because I requested a Exynos variant. Sprint said they couldn't (or wouldn't) give me one.
