Possible Root Maybe ! - AT&T Samsung Galaxy Note 4

I recently came across this article and its content intrigued me greatly. There is a "QuadRooter" exploit for devices using Qualcom chipsets. Maybe we can finally have root access on our beloved Note 4.

Sorry to break hopes an dreams... Exploits isn't the problem. We already have exploits to root. These exploits are just another way.
The problem is the locker bootloader and the kernel having DM-Verity. Once the system obtains root. The kernel reads that we have root which is DM-Verity than it removes root from the system. Which is why we only have a Temp root when we use Kingroot on 4.4.4 kitkat and 5.1.1 lollipop. This is why no developer wasted there time creating an app for root because we know it will only be temp.
There is no exploit for DM-Verity. Only way around it is with an unlocked bootloader, install a custom kernel with DM-Verity disabled. Now come Android 7.0 Nougat, verified boot (know as DM-Verity) will be "strictly enforcing" and won't allow your device to boot if the software has been compromised.

Okay, so Android will become more like iOS on Nougat and onwards? No way I'm sticking with Android then..
Whatever happened to Ubuntu mobile?

Well yes at least for most OEM manufacturers. I think Google is mostly doing this to help promote Nexus phones so they get a bigger market. Because if you have a Nexus or Oneplus you'll be fine with being SIM Unlocked and Bootloader Unlocked.
Personally I'll be upgrading in couple months with AT&T an I'll be giving this Note 4 back to them... don't see much point to keeping it if I can't root. An I'm upgrading back to iPhone because at least we all know Apple don't have much security an will have a jailbreak on iOS 10. They just got one on iOS 9.3.3 and other developers already have iOS 10 beta 3 jailbroken.
Android is still more open than iOS in the since of having SD cards, file management, being able to download from your Internet browser, running emulators on your phone like gbc, gba, ds, psx, etc. Unzipping / Opening RAR files. They just don't want you to have system access or management. Started with mostly Carriers (like Verizon and AT&T), but now I think OEM'S don't want us rooting either look at the Galaxy S7 is locked bootloader even on T-Mobile. just an example

I wish that we wouldn't have natively locked bootloaders as mandatory requirement for succeeding Android versions. That way, even if mainstream brands decide to lock all their phones, we'll still have those from the likes of Xiaomi and Oppo as options if you need or want root.
But, if it were the case, then I think we'd be better off with iOS with all the ecosystem that comes with it, along with fewer segmentation for developers, not to mention awesome accessories and even casings that iOS devices have.

Interesting

It's been a while since I flashed a custom rom, but been trying to get caught up again. From what I've read, the bootloader is lock in our AT&T Note 4. Isn't this the bootloader?

I am too jumping ship from android, if I'm going to spend some serious cash on a phone, it shouldn't be locked down, my daughter just received the iPhone 6s and loves it, I want full access to my phone again, been rooting for yrs

so who's been looking for root?

i know were building up this huge bounty thread, and everyone is definitely raising attention that we don't have root, but is anyone actually actively working on rooting the n4? I've been lurking around regularly while i wait for mine, but haven't seen anyone actually say they're looking for a root.
i just have this horrible picture in my head that everyone is thinking 'there's so many ppl here surely somebody must be working on something big, ready to drop an announcement any day now'.. and in reality the only ppl here are the ones asking if somebody else is doing something about it.
sooo who's been looking for root? what findings have you found so far, what looks exploitable, are you still waiting to get your hands on your note 4? yeah me too. anybody else have some useful exploits or findings to report?
lets do a status update

Root is a more obtainable goal! Think back at the last 2 Sammy devices with locked bootloaders, both have bounty threads, and neither was ever unlocked. Now look back and BOTH were able to obtain root. Yes unlocking the bootloader would make everything easier, but in terms of the probability, root will be obtained before the bootloader surface is even scratched. I hope I'm wrong, I would love an unlocked bootloader, but I'm highly skeptical that will ever happen, let alone before root or before Lollipop is FORCED onto our unrooted phones by AT&T.
I just want Adaway and Xposed. Why can't they just let me do what I want with the UI at least? I understand Adaway and why they don't want that but I should be able to kake an app full screen or change the dpi of an app if I want to..

Do you research root will not last without the bootloader unlocked. When Android 5.0 rolls out root will be broken on all devices PERMANENTLY unless the boot loader is unlocked. Samsung plans on rolling out 5.0 to the Note 4 in December. That means that even if root is achieved you are talking about only having it for 40 days. You will not be able to turn off updates. So eventually when you reboot your device it will auto install android 5.0 and break root for you forever. So go ahead and have a dev waste his time on getting root that will last about 40 days. The future of this phones root and custom development is all riding on unlocking the bootloader.
Don't count it out the LG G# on AT&T got the bootloader unlocked. But the effort needs to be on that not on root. Root is a waste of time.

yeah i totally see where you're coming from saying that, and can't say i wouldn't love to see my note on 5.0 too, but if it comes down to the features i 'need' vs the features i don't even know exist yet (5.0), I'd probably just choose to ride out my note 4 on KitKat.
it IS the touchwiz stuff that makes the note experience unique, not so much the new android versions.

This applies to all 3 of you.
You will be forced to upgrade to Lollipop even on a rooted phone because you won't have a customer ROM so AT&T will still push the update. Eventually when you reboot your phone it will upgrade you to lollipop. The only way to prevent this is to NEVER use wifi. Otherwise the update will start automatically and eventually it will upgrade you to Android 5.0 whether you like it or not.
So go ahead and "ride your bike" the the next 40-60 days, then AT&T is going to run it over with a bus and you will lose root forever without an unlocked boot loader.

I'm not sure that possible on this phone. There is a thread over in the t mobile section for the Note 4 addressing this. It is not a stand alone app on this phone. It is built into the system and probably can't be frozen. There are concerns that they will have to get a custom kernel finished before the update rolls out on that phone even though they have an unlocked boot loader, otherwise people will lose root for good.
Check it out there is a lot of chatter right now on the future of root for this phone, basically from all of the research I have done the only chance at all you can keep root is with an unlocked boot loader and a custom kernel. Before the update for 5.0 rolls out.

Yup. I will do the exact same thing if root is achieved before the push 5.0m I did it on my Note 3 and never had a single worry about Knox or any OTAs. I don't know why this guy is so adamant with the scare tactics.... Just give me root and I am g2g.

You know... I hadn't thought of that... LolliPop being pushed to our phones prior to being able to obtain root... without at least root, we can't disable the OTA and after "asking" a few times, it will just happen. Once that occurs, getting root seems even more unlikely than it already is...

You are terribly mistaken... If root is obtained you can disable the updates & OTA apk's, which would prevent the 5.0 update from being pushed down. But if AT&T starts pushing LolliPop BEFORE we get root, it's a done deal.
This might be the very reason we see a very accelerated deployment of LollioPop by AT&T. Haven't we all been complaining that the carriers take too long "certifying" OS updates before releasing them? Now we may not have that problem...

why NOT root?

given all of the cool options that open up with root, im wondering why NOT do it??
i mean other than no Android Pay, and having to manually flash rather than ota on phone, is there any real downside?

Those downsides are enough for some, but the biggest PITA is if you didn't unlock your bootloader then you have to factory wipe when you unlock.

stock rom nowadays give us most of the options that we needed to root for back in the day
i used the pixel 2 without root for 1 week (before it came out )
and the only thing i need it for was adaway and custom kernels
i used non-root adblocker and it's actually worked fine
so if i am stuck with a phone with no root i can live with it
I always root, but the big downsides are around OTAs and needing to jump through hoops from time to time to update.
Finally it's a security issue, particularly a unlocked bootloader, it's super easy to erase pin or pattern locks from twrp. Also malware in a root app could be devastating to any info you access via phone.

Because some security flaws that come along and some malicious apps expose the fact that you have root to be more effective.
If a good and stable rom like Pure Nexus that passes safety net works flawlessly on the Pixel XL 2 then that would probably be enough for me not to root. That would provide enough features and excitement to the already great experience that stock android now provides. Right now, i enjoy root in order to apply adaway and delete system apps if i so choose. Also nice to be able to use different color profiles. I am one of those that loves to be able to use Android Pay while rooted.

I don't remember. Sorry. :/
I used to be an avid rooter and custom rom user. For me, I'm contempt with the stock factory images. May give PureNexus a shot if it comes around.
Besides, I had an incident with Chase Bank once where I was having trouble getting text alerts. After an hour on the phone with support, they noticed and mentioned I had a "tampered" device. Not that my problem had anything to do with my device being tampered with (rooted), and not that I had any modifications which could cause harm to my banking information, but in the long shot case something did ever happen with your money, I'm sure the banks would have no problem pointing their fingers at your phone.
So if a company like Chase scans to see if your device is rooted, I'm sure most app developers do without telling you.
If someone wants to chime in, not exactly sure how apps see it if you have a rom like Resurrection Remix, or PureNexus, and actually dont root it. I wonder if the apps still consider the device tampered with if there is no root access

You can MOST definitely have Android pay with Root in Pixel. That is the beauty of dual partition setup. Have one partition rooted and other non-rooted, with both sharing the same data partition.
I had done this for the past year on the OG Pixel XL. The only time I would need non-root would be for Android pay - I would just boot to the other slot. Use Android pay and then reboot to the previously active slot after finished.
As for Custom ROM - I'm hoping against hope. Hard to imagine life without the features of PN or RR. However, it is not encouraging given that there is no a single OREO based Custom ROM yet for the OG Pixel XL. Who knows how many developers actually end up getting the Pixel 2 XL - which is more expensive. That is the only reason I'm still waiting with bated breath until my return period for Pixel 2 XL expires. Luckily, the One Plus 5t launches on Nov 16th and the reviews would be out soon. I know OP5 has RR custom ROM which is a big deal..

Yes to all this. I haven't rooted since my Galaxy S5. I was perfectly fine with my Nexus 5X stock and do use Android Pay often enough to want to remain unrooted. I actually used to root and install stock-like ROMs so now that I've been getting Google phones, I have no need.

doubts about whether to continue using root or unroot and relock the bootloader

Unlocking your bootloader and rooting your devices is a choice that you and only you can make. There are always risks when modifying your devices. When you unlock the bootloader on most devices it will void your warranty unless stated otherwise by the manufacturer.
When it comes to root access there is always a chance for things to stop working. That is why it is up to you to do your research and make an informed decision before taking any action.
To some people, including me, an unlockable bootloader and gaining root access over a device is a must. I am paying for it and I want to use my devices how I see fit.
If you are concerned about an issue that may arise because you have an unlocked bootloader and root access I always try to look at it from both sides. Why did I unlock the bootloader? Why did I root? Am I able to do what I intended to do or not?

I'm kinda in the same boat. While I don't use GPay that often (and I can currently use it through Magisk), occasionally it would be nice for it to work without issue. However, the main reason I root is so that I can manually edit my HOSTS file to block ads.
Like fast69mopar mentioned, it's an individual preference. What do you gain by unlocking the bootloader and rooting?
In my opinion, the OP7T is a fantastic phone right from the get-go. So was the OP6T. Both phones I used for almost a full week before unlocking and rooting.
Got the OP7T a month ago and was faced with the same decision. All phones since Samsung Galaxy I have rooted.
Decided not to root the OP7T. So far couldn't be happier. Maybe missed it once. Everything working without issue is nice.
As for Ads.
Built in Private DNS in Android 10 with dns.adguard.com works pretty damn good.
I'm rooted, using magisk and edxposed with aosip. Definitely no loss of function comparing to stock. I don't use Google pay, but Samsung pay, bank apps, snapchat, everything works. Currently magisk and edxposed could be hidden without any loss of function when it comes to bank or paying apps. I don't use Google pay but safety net passes just fine with my setup

Unlocking your bootloader and rooting your devices is a choice that you and only you can make. There are always risks when modifying your devices. When you unlock the bootloader on most devices it will void your warranty unless stated otherwise by the manufacturer.
When it comes to root access there is always a chance for things to stop working. That is why it is up to you to do your research and make an informed decision before taking any action.
To some people, including me, an unlockable bootloader and gaining root access over a device is a must. I am paying for it and I want to use my devices how I see fit.
If you are concerned about an issue that may arise because you have an unlocked bootloader and root access I always try to look at it from both sides. Why did I unlock the bootloader? Why did I root? Am I able to do what I intended to do or not?

Thanks a lot for your response
I actually rooted because I wanted to use substratum themes and enable aux module in gcam. Apart from that no other reason.
So I guess I am not missing out on too much .
I actually unrooted my phone and relocked the bootloader.
But again thanks for the response!
I had unlocked the bootloader and tried a couple of custom ROMs a few months back but decided it isn't worth it because my main hindrance of adblocking is addressed using DNS and any unneeded app can be disabled using adb. On the flip side, I need Widevine L1 for Netflix/Prime and no custom ROM can offer that on the 7T.
Makes more sense to me to stay within the walled garden, especially with the higher risk brought about by rogue Android apps that are now far too prevelent. The mods too are not that much value adding than it was may be when I first started using custom ROMs nearly a decade ago.

Is it worth to root your Samsung Galaxy S10+

Hello,
Yesterday, I successfully rooted my Samsung Galaxy S10+. But since I still had some questions about it, I went on and posted a thread here. User Spaceminer then pointed out that my original post was in the wrong subforum and linked me here. Naturally, I looked at some of the most popular posts in hopes to find answers to my questions. But what I found confused me more than it gave me answers.
Since 2014 with the Samsung Galaxy S5 I got used to rooting in order to disable bloatware, protect my data and customize my phone. I continued doing that with the S8+ until I recently got my hands on the S10. Now, my main reason for rooting are still the same; I want disable (not necessarily uninstall) bloatware, protect my privacy and customize my phone (such as changing the background of the dial when calling someone). But that thread made me wonder if it is even essential to root. I also found a similar post on reddit and most answers seem to agree that it is not necessary to root your phones.
Now, my situation is a bit different. For one, I already rooted my phone. Second, I don't care about warranty nor custom ROMs. But I do want to install a banking app. Also, it is a bit cumbersome to not only have to manually update your phone with every update but the booting requirements with the warning screen are also a bit annoying. So, my question is the following:
What are the advantages of rooting that are not possible without? I have 3 main concerns: Bloatware, Privacy and Customization.
The reason why I posted this in a separate threat is that I was not able to come to a definitive conclusion on my own and most discussion threads are over a year old. By now, the whole process of rooting and what is possible changed since then, so I want to get a more recent insight. I hope you can help me out.
With kind regards,
DasMalzbier
Tbh root is not needed, unless you want to use a custom rom. Most things are already in the android now.
Calyx os not make for samsung Galaxy series and 12 update also comes this year so i think rooting is unnecessary for s10 series
Root is 100%, absolutely necessary for using the phone. I cannot use any phone without it. Critical root-only capabilities:
full system backups (in twrp)
titanium backup
disable updates permanently (update ONLY when want to)
app freezers (app quarantine)
disable/remove bloatware
disable google play services/google play
automate/tasker
cf lumen
adblockers
wifi tether
busybox
superuser
ssh tunnel
update android to later version / install custom roms
optimize system
button mapper
custom theming / substratum
nav gestures
tidypanel
xposed
root explorer
app privacy customizations
3c all-in-one toolbox
more
Without root, the phone is unusable to me. I will never buy any phone without root capability. I am willing to go to different carriers just to get root on the device, or go to different manufacturers if root is blocked. For example, I will never buy a huawei device - they are locked.
I would like to say yes but I can't. the stock apps are very well designed.
The biggest concern is that custom Roms are released faster than modded apps.
For example I tried about ten GCAMs and all of them have a bug... and it becomes more complicated with Exynos.
OpenGcam is not worth samsung app.
Unable to get voice match to work.
Alarms that you can't set to a specific day with the google app.
And so on.
Root is useful when the manufacturer no longer updates the devices.
I regret having Root mine because I lost Samsung Pay and other things.

The only one that would have any consequence of rooting is Samsung Pay.

No, even if you wanna use custom rom you don't need to root. Just pick the rom with the apps you want or just use the gapps packages you want, if want essential to work gapps then use pico or nano. If there is still something you want to remove and the romdoesn't allow, just use adb shell commands and thats it. Less issues with banks not working because of Magisk (root). I know Magisk has a feature to hide itself, change its name but depending on the app, the libs can be found and know that is Magisk, so for security purposes some apps don't work and some aren't even shown in the Google Play Store just because you rooted the device.

maybe now the root is not needed but later down the road when your phone will get obsolete and newer android OS updates will be halted for S10+ then you'll be more attracted towards custom roms. Actually it is just personal preference.

It's happening right now, I doubt S10+ will receive Android 13 and now just security and bug fix updates are being shipped by Samsung.

It won't get any new Android upgrades AFAIK.
But appart from tripping knox, what else do I lose if I unlock my bootloader? I read once, quite a while ago, that the battery is limited to 80% of its full capacity. Is that true?

Depending on the version, you'll notice stock camera to be limited or not work as expected, secure folder, dual messenger either not working, it can trigger some banks or payment apps (especially if you root), no more ota updates (if you keep using stock rom), drm content can stop working, samsung pay, Play Store might limited the apps you see and so on... Not sure about the battery, for me unlocking the bootloader and switching to another rom made my battery last more than stock, but it depends on the rom, the device, it's not a rule of thumb.

General XDA Article: PSA: Dirty Pipe, the Linux kernel root vulnerability, can be abused on the Samsung Galaxy S22 and Google Pixel 6 Pro

PSA: Dirty Pipe, the Linux kernel root vulnerability, can be abused on the Samsung Galaxy S22 and Google Pixel 6 Pro​
What happens when a Linux privilege-escalation vulnerability that also affects Android gets disclosed publicly? You got it! Security researchers and Android enthusiasts around the world try to take advantage of the newly found problem to create an exploit, which can be used to gain advanced access to your device (such as root or the ability to flash custom images). On the other hand, device makers and a few determined third-party developers quickly take the responsibility to patch the backdoor as soon as possible.
This is exactly what happened to CVE-2022-0847, a vulnerability dubbed “Dirty Pipe” in Linux kernel version 5.8 and later. We talked about the exploit in detail last week but didn’t explicitly cover the potential abusing scenarios on Android. Now, XDA Member Fire30 has demonstrated an exploit implementation around the kernel flaw that can give the attacker a root shell on the Samsung Galaxy S22 and the Google Pixel 6 Pro.
The key point here is that you don’t need any kind of unlocking or other trickery to make it work – the Dirty Pipe exploit allows the attacker to gain root-level access on the target device through a reverse shell via a specially crafted rogue app. At the time of writing, flagships like the Google Pixel 6 Pro and the Samsung Galaxy S22 are vulnerable to the attack vector even on their latest software releases, which shows the exploit’s potential. Since it can also set SELinux to permissive, there is virtually no hurdle against unauthorized control over the device.
From the perspective of the Android modding scene, Dirty Pipe might be useful to gain temporary root access on otherwise difficult-to-root Android smartphones, e.g., some regional Snapdragon variants of the Samsung Galaxy flagships. However, the window won’t last long as the vulnerability has already been patched in the mainline Linux kernel, and OEMs will probably roll out the fix as part of the upcoming monthly security updates. Nonetheless, stay away from installing apps from random sources for the time being to protect yourself. In the meantime, we expect that Google will push an update to the Play Protect to prevent the vulnerability from being exploited via rogue apps.

This isn't necessarily bad news if the exploit is used non-maliciously. Could be beneficial for Verizon customers looking for a way to gain root.

Could, yes. I'll remain pessimistic that it'll actually happen, and of course, it'll take someone willing to actually do the work. A very limited time to do it doesn't help unless someone with a spare Verizon device keeps it off the network/internet until something is implemented.

I was just reading about this & that exact thought came to mind. The root access gained seems to be temporary, but if you can write to usually read only file system, could you not theoretically write a Magisk boot image (using dd, or in Magisk Manager itself?) or even toggle the OEM unlock switch via a SU shell command unlock the phone?
I'm not very well versed on how the mechanics behind OEM unlock switch in developer settings works & or how Verizon locks these phones down (UK based), but I would assume that it could be useful to help find a exploit for phones running any pre-April 22 update.
Edit: from my limited knowledge, can you not sideload a earlier OTA on Verizon devices? I know you could do so with Pixel 3 and earlier, but I haven't been following it too closely with later devices.

I've never heard of a shell command that could toggle the OEM unlock. That doesn't mean it hasn't existed, but I doubt it, otherwise, I would think on all the Verizon devices I used to have, and just root threads in general I should remember anyone making the suggestion, even if it required temporary root first.

I was under the impression that all phones with the bootloader locked that you could never, ever downgrade via any method. Also, OTAs generally use deltas/differencing to patch known good files of version A to version B, and B to C, so applying a version B OTA to a device that's on version C would fail because the files on the device are the wrong version.
Like (let version A be represented with the value 1, B with 4, and C with 9):
Device is on version B, so "4".
OTA to go from B to C comes.
OTA says is device file "4"?
Yes! Add 5 to the file, it's now "9".
and then
Device is on version C, so "9".
Try to put the B to C OTA on the device.
OTA says is device file "4"?
No! It's "9", quit OTA process.
This might be simplified, and anyone correct me if I'm wrong, but this has definitely been the case some and I believe almost all, if not all, the time. The OTA files can be smaller that way because they don't contain replacement files. They only contain what the difference is between the old file and the new, which is usually much smaller than the entire file.
