Wow. Still on 4.4? I thought there's a lp update?

---------- Post added at 10:55 PM ---------- Previous post was at 10:52 PM ----------

If u are on 4.4, there is a root method. U know that right?
[AT&T Samsung Galaxy Note 4] nemopsp:
Only Temp root with kingroot... you can install SupeSU-me pro to remove it an install SuperSU but the temp root is unstable it take a couple tries before it even works.... which takes time than after you get SuperSU installed over time in about 30min to an hour you lose root an than the system eventually becomes unstable by rebooting randomly. Than you have to start same process all over...

Exploit vuln

Just checked and the ATT note 4 is vulnerable to

Cve-2016-2059

Cve-2016-2504

Cve-2016-2503

Cve-2016-5340

Would these be any use?
[AT&T Samsung Galaxy Note 4] dergezero:
the issue isn't root, its DM-Verity and someone developing an unlocked bootloader.
[AT&T Samsung Galaxy Note 4] annttiigs:
is this a bait or someone is really working on such bootloader.
[AT&T Samsung Galaxy Note 4] nemopsp:
No this means no matter what exploits we have to obtain root. DM-Verity kicks in an removes it from the system.

We need a bootloader unlock to install a custom kernel to disable it. So far there has been no exploits for DM-Verity. But we do have bootloader exploits tho developers moved on to newer phones... an I know one of the exploits won't work because we don't have a developer edition of the N910A model.
[AT&T Samsung Galaxy Note 4] Phatboyj420:
We don't all have $200.+ to put down on a device that we already own , but yes that is the conclusion I had already come to.

They are calling these vulnerabilities "Quadroot" collectively and creating a huge scare among the sheep people.

Sheep People are not just Apple fanboys anymore also people who think locked boot-loaders on all devices is good for all

along with all of the other flagship device changes that are made to appease the mainstream market, I mean Sheep People Market. Like the new Samsung Branded Apple Devices, the Samsung Galaxy S 7 & Note 7 are the most recent upgrade to our AT&T Note-4 that we already know to be an AT&T/Samsung branded Apple device it just happens to still include a removable battery witch will be lost with any future upgrade no-matter your choice do-to the Sheep People Market. Hopefully you all get where I'm going with all this.

[AT&T Samsung Galaxy Note 4] boofman:
Looks like the Note 7 already got root on all carriers. Still can't believe why the Note 4 ATT Variant won't have it, and its just sad we will never have it.
[AT&T Samsung Galaxy Note 4] Dullaz:
Is there something special about the ATT variant? Why can't the root process for the other note 4 models be adapted? I'm so confused about what needs to be done. Anybody wanna enlighten me about what's stopping this root?
[AT&T Samsung Galaxy Note 4] nemopsp:
Well have exploits for root. But are issues is DM-Verity. Do a little Google searching about it. It's a security layer in the kernel they added since 4.4 kitkat.

The one thing I don't fully understand is they get around it on the Galaxy S7 but we are still stuck... but at end of the day developers moved on to newer device an no one cares about the Note 4 now because most people already upgrade since it's about to be 2 years old now.
[AT&T Samsung Galaxy Note 4] Dullaz:
How do we tempt the Devs to work on it? I'm all up for funding a small bounty for this.
[AT&T Samsung Galaxy Note 4] boofman:
There already is a bounty, but nobody seems to be interested anymore..
[AT&T Samsung Galaxy Note 4] KennyG123:
I thought I read somewhere about a leak that helped them with the Note 7. No such leak ever came for the Note 4. Without cracking the Note 4 bootloader the kernel can't be replaced to remove dm-verity. Devs did all they could for the AT&T Note 4.
[AT&T Samsung Galaxy Note 4] nemopsp:
Well to be a bit fair here we have 2 bootloader exploits but I have yet to see a developer try to use it or modify it. The longer we wait it's only going to get harder because with Android 7.0 Dm-verity will be strictly enforced. Plus N910A don't even have 6.0.1 MM yet so they still have a temp root as of now on 5.1.1 LP but soon that ticket will expire with the release of 6.0.1 MM and kingroot will no longer work. Until a future update...

As for the Note 7 it's newer and locked for all carriers so it made more developers look at it.
[AT&T Samsung Galaxy Note 4] Samsung8600:
Sign the petition :) I did... 1.755 more to go ???
[AT&T Samsung Galaxy Note 4] Kyuta Syuko:
DM-Verity and the inability to flash a kernel, due to locked bootloaders, that has it disabled is what's preventing root on the AT&T variant. Verizon was also having this issue, but there's an exploit that enabled them to replace their locked bootloaders with unlocked bootloaders from a dev edition of the phone which AT&T does not have.
[AT&T Samsung Galaxy Note 4] elliwigy:
as stated, the s7 and note 7 are very similar/identical.. the only way we were able to obtain root is due to engineering files leaked that are signed and work on each variant that allows modification to obtain root.. technically didnt start as an exploit until we pushed root as we are technically using samsung debug/signed/engineering files..

S7 I believe was an eng boot or kernel...

note 7 its an entire sprint eng/debug tar

both able to be flashed through a modified odin and pass the security checks.

vzw note 4 was unlocked due to exploit in changing the eMMCID to match that of a developers edition which allows unlocking but was only available on vzw since no other carriers had a developer edition.

its mostly luck and a little knowledge imo to piece it all together.

Heck I have a cricket LG Spree (garbage phone) that isnt rooted as well as the s6e, s6 and most likely others have either never been rooted or werent rooted past Lollipop so users were stuck or upgrade n lose root
[AT&T Samsung Galaxy Note 4] Tetragrammazoid:
I am looking at the same file right now. Tencent marked as belonging to "Kingroot."
[AT&T Samsung Galaxy Note 4] webbie2:
just crazy how there have been phones with locked bootloaders in the past and they were able to get passed them by installing a 2nd boot loader or using safestrap. its so odd to me.
[AT&T Samsung Galaxy Note 4] elliwigy:
thats not true.. you need an unlocked BL to use custom BLs (not for eng bl however but this wouldnt be unlocked) and you needed root befre you could even use safestrap
[AT&T Samsung Galaxy Note 4] exxTErno:
Well, I gave up, now that MM is out seems that that´s all there is for the Note 4, I really don´t think anythig new will come out now without root, exchanged mine for a Sprint Note 5, this is it for me but wish you all guys good luck on this rooting task.

Farewell!!:fingers-crossed::fingers-crossed:
[AT&T Samsung Galaxy Note 4] sharp1114:
From this and everything else I've read, it's sounding like post-marshmallow, rooting a Samsung device is pretty much impossible. It also looks like this is an ATT problem. Is this the new norm for Samsung in general, Samsung on ATT, or ATT in general?
[AT&T Samsung Galaxy Note 4] KennyG123:
AT&T. Verizon would be screwed too if they didn't have a developer edition to steal from.
[AT&T Samsung Galaxy Note 4] sharp1114:
So best bet is to jump ships to Verizon, or would that be out of the pan and into the fire?
[AT&T Samsung Galaxy Note 4] KennyG123:
Why not T-Mobile or Sprint?
[AT&T Samsung Galaxy Note 4] sharp1114:
Availability. T-Mobile and Sprint both have very sparse coverage in my area. Why? Am I looking at the same problems with Verizon?
[AT&T Samsung Galaxy Note 4] KennyG123:
Verizon model had to be tricked a bit using the developers model bootloader. So you will be fine for now.
[AT&T Samsung Galaxy Note 4] elliwigy:
i would say screwed regardless.. verizon and att were difficult as it is but as of late making devices similar or identical between carriers and most flagship phones from Samsung no longer allow BL unlocking on any carrier except international variants
[AT&T Samsung Galaxy Note 4] gcodori:
You're best bet on any carrier is to bring your own phone.

Know what you are buying before you enter into a contract.
[AT&T Samsung Galaxy Note 4] gremy1987:
That's true. Most companies will keep adding security to make it hard to you to do anything, so they can use your cellphone to anything they want.

[AT&T Samsung Galaxy Note 4] DamnCampers:
Has anyone seen this latest link http://bbqand0days.com/Pork-Explosion-Unleashed/ and checked to see if it will work for our device?

I don't have access to a computer to check it myself. It would appear you need to have adb setup, have debugging turned on your phone, and have already authorize a usb connection via adb. That appears to be what is needed prior to issuing the command. If it works, it might finally lead to disabling SElinux as it bypasses a locked bootloader.
[AT&T Samsung Galaxy Note 4] Tmobilefan906:
T-Mobile devices work fine with att sims. They're both gsm phones.
[AT&T Samsung Galaxy Note 4] hkjxda:
Tried the adb command. Doesn't work.
[AT&T Samsung Galaxy Note 4] boofman:
Bummer. I wad hoping we could do something that would lead to having root.
[AT&T Samsung Galaxy Note 4] Dark_Voltz:
So nothing basically?

I just got the Note 4 I currently using an iPhone 6S since I really want to try out how android is to its best but seems I made a huge mistake buying the AT&T Version of the Note 4. From the looks of it there's no root on 5.1.1 however if I downgrade there is?? Just confused since there's so much answers here but I might as well downgrade since I could probably just use MultiRom to boot multiple roms such as the 5.1.1 version and compare each one.
[AT&T Samsung Galaxy Note 4] DamnCampers:
Once the note 4 has been upgraded to 5.1 lollipop you can not downgrade back to kitkat. The root that exist for the AT&T note 4 is just a temp root as the note 4 has a locked bootloader.
[AT&T Samsung Galaxy Note 4] Dark_Voltz:
Oh wow that sucks :/ I just figured out as well seems like AT&T is like the same thing in terms of Apple way updating iOS to make sure it won't be jailbroken. Just another question though what do you mean by temporary like it would be gone after reboot basically?
[AT&T Samsung Galaxy Note 4] DamnCampers:
By temporary root it will do one of two things as both were reported. The first being that the system would over time lose root for no outward reason. The second being that every time the phone was rebooted it would lose root and any changes done would revert to the prerooted settings.
[AT&T Samsung Galaxy Note 4] CCJ22:
Well, I'm selling my note 4 and getting a Nexus 6. **** this not having root stuff.
[AT&T Samsung Galaxy Note 4] ringnutz:

i dont think theres much visibility at this point but hope someone is still working on it for u folks
[AT&T Samsung Galaxy Note 4] spocko:
Even if we were able to get root using one of these exploits, I'm not sure it would help. We'd still need a way to get past dmverity. Same situation we had with Kingroot.
[AT&T Samsung Galaxy Note 4] nemopsp:
There is a new Linux exploit around called "Dirty Cow" not sure if this can help us obtain root.

But I feel like just as the other exploits we have it will not.

This would be amazing if this works. I wish a Dev would have took this phone on as a project because its such a hard phone to get rooted. this would have made a great rooted device especially now. This is when i wish i know more about android development!!!!!
[AT&T Samsung Galaxy Note 4] elliwigy:
it was rooted a long time ago..many devs did look at it but was determined you needed an unlocked BL
[AT&T Samsung Galaxy Note 4] boofman:
I wouldn't mind having even just temp root, so I cab remove the bloatware that's on in here..

Though it would be best if we can get perm root so we can have goodies like xposed, viper4android, maybe even Touchwiz-based custom roms (wouldn't want to lose full Spen functionality)
[AT&T Samsung Galaxy Note 4] elliwigy:
even with simple root you still need to bypass write protection.. id think only option is unlocked BL but what doI know

What about this

http://www.androidsage.com/2016/08/...ndroid-6-0-1-marshmallow-n910auu2epg7-update/

Im still on 5.0.1 whil this work?
[AT&T Samsung Galaxy Note 4] CrimsonMaple:
Dirty Cow could be used to root the Note 4. However it is difficult to gain root shell beyond android 4.4. Luckily enough you can downgrade using ODIN. It is possible to use this exploit on Lollipop. This allows for an ADB shell in root and could be the start of a temp root. I'm looking into a root using this exploit.
[AT&T Samsung Galaxy Note 4] marcimix:
I don't have any idea how I changed the language by smth like Morelocale 2 app via temp root cause dm-verify.

There can be a hole?
[AT&T Samsung Galaxy Note 4] will5:
J5 has some kind of dm-verify and has been rooted anyway.

Not sure if this helps.

I think s7 has the same kind of verification.
[AT&T Samsung Galaxy Note 4] boofman:
I don't think there are enough Devs interested with the 910A anymore, they might have moved on to other devices..

But I do hope somebody can have a look into this.
[AT&T Samsung Galaxy Note 4] DamnCampers:
As I have been following the dirty cow development thread this came up today http://xdaforums.com/showpost.php?p=69834968&postcount=320

It appears that someone has figured out how to do a tethered temp root on the galaxy s7 active by hijacking a couple processes and focing the system to use an alternate SElinux policy.
[AT&T Samsung Galaxy Note 4] p1gnone:
dr. fone solution?

Ran across a youtube video: "Root ANY Android One Click 7.1.1, 7.0.1, 6.0.1, 6.0, 5.1.1, 5.1" . Got excited and instead of paying the $30 I opted for the free trial. I'd be willing to pay up if it worked.

Well it FAILED, but there is a curious claim on https://drfone.wondershare.com/reference/android-root.html search for our model: SM-910A... It's there, but with 5.1.1 android listed.

Anyone still on 5.1.1 who has tried it? I'm not sure if downgrading from 6.0.1 to 5.1.1 will help us. Thoughts?
[AT&T Samsung Galaxy Note 4] DamnCampers:
I'm still on 5.1.1 as my device got bricked two days ago and I just to it restored yesterday. I had to do a full flash so it's pretty much a clean phone minus all my apps that I had reinstalled after I got it up and running. I'll try to take a look at it later today when I'm at work if I have time so that I can restore my phone if need be if it is a flop.
[AT&T Samsung Galaxy Note 4] jboucher614:
These things almost never are what they promise. This company you're talking about hasn't done something no one else could with the Note 4. If they are a "legit" company, they only have the capacity to root phones that anyone else could got free. It's like in iOS jailbreaking where they try to sell jailbreak for versions that are currently unjailbreakable.

Nobody has a bootloader unlock for N910A, no matter how much you pay. (it's also less and less likely there ever will be one) No bootloader unlock=no root
[AT&T Samsung Galaxy Note 4] ast32:

I looked around and, www dot androidsage dot com/2016/06/28/how-to-root-galaxy-note-4-on-android-6-0-1-marshmallow-sm-n910hftpcr4/

seems to be root images for most marshmallow Note 4 devices except for the N910A. Is that page legit?

The problem is that I especially bought a new Note 4 for the purposes of rooting it. [Which arrived today. :)] I have already upgraded it to Marshmallow.

And now I found the N910A is not supported :(

Is there any developer I can pay to make a root image?

Should I downgrade to Android 5.x.x? Is this the only way I am going to get a rooted phone?

Thanks!

[AT&T Samsung Galaxy Note 4] paulsheer:
Can anyone recommend if I should return this Note 4 and rather get a Note 5?

Paul
[AT&T Samsung Galaxy Note 4] ast32:
Yes, if it's a reasonable cost difference for you. Also, confirm in the Note 5 forum if the model you're buying has a potential to unlock bootloader, and root, even if you don't plan to do it. Hell, if you want this phone, get a model that's not the N910A. AT&T and Samsung screwed this phone over.

Open phones generally are easier to debug and keep alive should you face any stock issues.
[AT&T Samsung Galaxy Note 4] paulsheer:
which model number Note 4 do you recommend? Note 5?

I have an AT&T contract and SIM which I am going to continue using.
[AT&T Samsung Galaxy Note 4] ast32:
As long as it's unlocked you can use any model of Note 5 with AT&T. Unfortunately, I don't know on top of my head what options are best for you when it comes to Note 4s. I do recall reading that international variant of Note 4 don't have all the basebands that AT&T use so your LTE can be limited.

I'm on the Nexus 6P, which is a hell of a phone if you're looking for a deal right now.
[AT&T Samsung Galaxy Note 4] paulsheer:
well all of the Note 5 phones on Amazon are Android 5.x.x.

The Note 4 I had *was* on 5.x.x before I upgraded it. So I might as well downgrade the Note 4 and then use the Note 4 rootkit -- which seems to be available. But you are suggesting here that the Note 4 cannot be rooted at all -- is that right?

Most people have a phone and are trying to find out *if* it can be rooted....

I should say I am not in this category: I need a rooted phone and it has to be a recent Note model. It needs to have proper AT&T LTE support too.
[AT&T Samsung Galaxy Note 4] ast32:
N910A is the AT&T model Note 4 and it cannot be rooted. To clear any miscommunication, just because you buy a Note 4, does not means its compatible with the rootkit. It's highly dependent on the model variant. Samsung often makes multiple models of one phone for different markets/carriers and most models often end up in the US at some point.

The Note 4 alone has many different variants (more than I listed):

N910A (AT&T);

N910T (T-Mobile)

N910V (Verizon);

N910F (Europe);

N910K/N910L/N910S (Korea);

N910C (Asia, Europe, South America);

N910FD (United Arab Emirates);

N910FQ (Turkey);

N910H (Asian Pacific);

N910G (Singapore, India, Australia);

N910U (Hong Kong, Taiwan, Australia, New Zealand, Chile);

N910W8 (North America)

It'll be up to you to figure out which one best fits your needs. The N910T is the T-Mobile version, and as long as it's carrier unlocked, AT&T subscribers should have no problems. Trust me, the research will seem tedious, but the knowledge you gain will prepare you for future purchases and development.
[AT&T Samsung Galaxy Note 4] paulsheer:
Thanks -- i see.

It seems the only difference between the N910T, N910W8, and N910A is as follows:

N910T ==> LTE Cat4 700/850/900/1700/1800/1900/2100 (Bands 1,2,3,4,5,8,12,17)

N910W8 ==> LTE Cat4 700/850/900/1700/1800/1900/2100/2600 (Bands 1,2,3,4,5,7,8,12,17)

N910A ==> LTE Cat4 700/850/1700/1900/2100/2600 (Bands 1,2,4,5,7,17)

What does it mean in practice that I'll be missing "frequency 2600" and "band 7" if I get the N910T?

Is the N910W8 for Sprint the same as any other N910W8?

Can I just confirm: this will give me Android 6 (Marshmallow) and I can root it?

According to autoroot.chainfire.eu there is a 6.0.1 root for both the N910T and N910W8, so this is ideal if it works.

Well if this is all true, then that's fantastic and I've solved my problem with no extra expense. :)

Paul
[AT&T Samsung Galaxy Note 4] ast32:
Certain bands allow access to spectrums with lower/higher speeds on the networks that support them.

AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands but it all depends on area if they own a license. LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently. This is different among carriers and regions (different countries).

I'm not sure about the Sprint variation. But if it's the N910W8, I doubt it's different than the North America N910W8. And if that's the case, and chainfire says its root capable, then it sounds like you have a match. Just make sure it takes SIM cards and is carrier unlocked.
[AT&T Samsung Galaxy Note 4] paulsheer:
:good:

It seems I have a few days to decide to return the N910A.

I'll monitor this thread if anyone has any more info.

This is all very useful information because the N910W8 seems (from the Bands) to be the "universal" USA model, and if it can be Marshmallowed AND Rooted, then it's about the best option for someone that wants a cheep "Big Screen" rooted smartphone right now. :cool:
[AT&T Samsung Galaxy Note 4] PeteTheGreek:
Here's my story, i got an AT&T Note 4 unlocked and using it with a T-Mobile sim card.

Do i benefit from rooting it with the N910T root? Is it possible? should i just wait for the N910A?

Thank you in advance.
[AT&T Samsung Galaxy Note 4] ast32:
You would have the N910A (AT&T) version, and you won't be able to root. N910T is the T-Mobile variant and can be rooted.

I have an unlocked N910A for AT&T and used it on T-Mobile. If there's any real progress in root, it'll be 1-2 devs working on it, and I wouldn't blame them if they give up. There's better phones out that are a lot less trouble.
[AT&T Samsung Galaxy Note 4] jboucher614:
You have unlocked the phone to use it on another carrier, not unlocked the bootloader. These are two different things. The N910A is not rootable, you still cannot root. Sorry
[AT&T Samsung Galaxy Note 4] The Tinkerer:
Would it be possible to swap the main board in a N910A to one from a N910W8? A new main board is loads cheaper than a new/used N910W8 and would have the unlocked bootloader required for root.

Just a thought.
[AT&T Samsung Galaxy Note 4] jboucher614:
I know someone did it with the board from an N910T so I don't see why not. Keep in mind, these devices are getting older and older and it's pretty much to the point that getting a different device would be what I would advise. Also, a lot of Note 4's have started failing due to hardware issues lately.
[AT&T Samsung Galaxy Note 4] paulsheer:
I'm still on a Note 2 from July 2013.

My new note 4 has to last me 3 years at least.

By that time the Note 8 will be rooted and pretty cheap I hope.
[AT&T Samsung Galaxy Note 4] paulsheer:
So I won my eBay bid ($275, shipping incl.) for a Note 4 International version N910C -- woohoo.

[AT&T Samsung Galaxy Note 4] DamnCampers:
I've been following some of the dirtycow development in another thread here on xda. The issue that I've seen so far with it is that you can use it to spawn a shell with the same privileges of the file you take over. It looks to only be handing out only read and modify access, but no ability to write files. There has been better success with phones with an unlocked bootloader, which we don't have. At best that I've seen posted here on xda thru the thread that I am suscribed to is a tethered root for a s7. I linked a while back to the section here on xda that has the thread that I'm following. If you can't find it feel free to pm me and I'll dig it up for you.
