kingroot just had an update yes I have the sm-n910v from verison and yes im still hopeful for root ... well I tried rooting with this app and it was successful .... however it rebooted and I lost it ... did it again and I can access supersu ... it tries to install and fails ..... I did root checker and it says I have root .... im confused and hopeful ... update busybox installed also

#$@#$^* rebooted
[AT&T Samsung Galaxy Note 4] nemopsp:
What software update are you on 4.4.4 kitkat still? Because you could have temp root for months now almost a year come may.
[AT&T Samsung Galaxy Note 4] happy2472:
5.1.1
[AT&T Samsung Galaxy Note 4] nemopsp:
Hmm so they found a new exploit for 5.1.1 finally? Can you show me a screen shot of post a picture of root checker on 5.1.1?
[AT&T Samsung Galaxy Note 4] DamnCampers:
I can confirm that it does seem to display phone as rooted. It failed on kingroot 4.8.0, but seemed to go thru on 4.8.1 after updating from within kingroot. Phone is stable for about a minute then goes thru a forced reboot.
[AT&T Samsung Galaxy Note 4] nemopsp:
I see, interesting so I'm better staying on 4.4.4 still more stable
[AT&T Samsung Galaxy Note 4] valsivief:
also Samsung galaxy note edge had today a temp root but it's gone when i reboot it
[AT&T Samsung Galaxy Note 4] DamnCampers:
Just to clarify for anyone that comes to read the thread kingroot 4.8.1 works to temp root until reboot on 5.1.1 with baseband n910aucu2doi2. I have only tested this thru the apk.

I remember one of the devs here created an app that's on the play store, but I can't remember the name of it. Would this now work for us to stop the reboots? And if so would it work with the apk or only the desktop version of kingroot?
[AT&T Samsung Galaxy Note 4] nemopsp:
I believe the app your thinking is SuperSUme Pro but I'm still on 4.4.4 thinking should I update to 5.1.1 now an try it cause yea I still lose root over time on 4.4.4 but it don't reboot. Plus xposed modules works with the new xposed I believe you can't get it on 5.1.1 without flashing with TWRP. Which can't don't on a locked bootloader
[AT&T Samsung Galaxy Note 4] giga8547:
On the at&t variant at least even with 4.8.1 on andver 5.1.1 once you root the keyboard stops working until reboot i believe the root method they are using uses a security flaw in the stock keyboard to obtain root i have not had a chance to test a non stock keyboard after root.

A few other observations is that if the phone locks up you can hit the menu key and it will un freeze for a bit and stop it from force rebooting i had root for over 20min testing it out by doing the menu key every time it stuttered. But i did notice when root is active the phone gets quite hot around the microsd and sim card slot im not sure if this is because the phones cpu is working over time to keep up with the system trying to reject root and fix its self of what causes it.

I would say this current temp root is a step in the right direction but it is not reliable at this point hopefully with this small but good breakthru it will get more stable and useful so we can do things like change the permissions so we can move files directly from internal to external storage without using the stock file explorer which imho sucks.
[AT&T Samsung Galaxy Note 4] nemopsp:
Honestly you say its a step in right direction, tho sounds like the same root from back on 4.4.4 kitkat! That all kingroot did on 4.4.4 is root than freeze after like 10mins, but try using SuperSUme Pro an remove kingroot app and install SuperSU and see if root last a bit longer and doesn't force reboot but should still lose root over time.

Here is a screen shot of my Note 4 on 4.4.4 kitkat N910A model:

But I changed DPI an Status Bar, not sure if you can do this with 5.1.1 temp root, but I'm kinda curious.
[AT&T Samsung Galaxy Note 4] DamnCampers:
Just tried using Supersume pro to see if it would work like one kitkat. It's a no go right now as it will prevent kingroot from working, but hangs on step 2 during the processing stage. Then you are left without a working keyboard due to kingroot and a borked reboot that will require a battery pull to cycle the power.
[AT&T Samsung Galaxy Note 4] happy2472:
sorry if I caused some hopes to be crushed ... maybe I should have tested it a bit more ... just hate not having root ... good thing my gf got the nexus 6 and is going to swap phones with me so I can have a rooted phone .... was going to upgrade to nexus 6p but most carriers no longer will carry the nexus phones anymore
[AT&T Samsung Galaxy Note 4] nemopsp:
Thanks for the update! I'll stay on my 4.4.4 flow, but I wonder if [MENTION=3178012]gatesjunior[/MENTION] is still updating SuperSUme Pro? But did you try the 9.2.6 version ? Maybe I'll be updating to 5.1.1 soon via Odin if this become as stable as the 4.4.4 temp root.
[AT&T Samsung Galaxy Note 4] DamnCampers:
I used the version that is on the Google play store, so I believe that is the most current version. Let's give it a bit and see what happens from here. This has gotten me all giddy as it reminds me of when the temp root for kitkat came out. I just hope there is a fix for the stock keyboard not working that gets rolled into everything for 5.1.1 temp root.
[AT&T Samsung Galaxy Note 4] giga8547:
Yes it is a small srep in a good direction for me at least. My phone shipped from att with non downgradeable 5.0.1 So i came from a fully rooted note 3 to a locked down note 4 all be it for free bit still.

Anyway i did a little testing supersume installs and gets root but looses it on a couple minutes less than 3 but some how kingroot is able to keep root for a good while. Also i found away around the stock keyboard issue i just installed the google keyboard from the playstore and it worked great. The system still freezes a good bit. Now my qiestion is. Can we change say the security setting to allow external sd card writing by anyapp and that stick after root or would it reset on reboot as In will that change be overwritten by a backup copy of the file on reboot.
[AT&T Samsung Galaxy Note 4] nemopsp:
No we can not change anything to the SD card to let us hold root. The reason why we lose root and this has been the issue since 4.4.4 is that in the kernel there is a dm-verity, which this is a system write protection that talks between the bootloader, kernel, and checks the system for root. Once it reads that the system has root it's freezes and reboots and than the phone is returned back to the way it was before you rooted. Example while with root you can remove a system app just so when the phone reboots the app comes right back. No one has found away around this and the only way is a custom kernel with dm-vertiy disable, which on phones like AT&T and Verizon with locked bootloaders are stuck. This will probably be the only root progress on 5.1.1 sadly! We need that bootloader unlock which that either will never happen or it will but by the time it will get released you have a new phone already so it won't even matter. We know a dev. has have a Galaxy S5 bootloader unlock tho its not released and he don't plan on releasing it any time soon plus it probably don't even work on the Note 4...
[AT&T Samsung Galaxy Note 4] dekatch:
Hi Guys, i did a search "Ping pong note 4" and this thread seems to be the only one where both Keywords were mentioned togheter.

So, is there ping pong root Or another rooting method for our beloved note4 which doesn't trigger Knox ?

I apologize if this question was answered already

note 4, 910f, Android 5.1.1
[AT&T Samsung Galaxy Note 4] giga8547:
Damn is all i can say lol wish we had someone on the inside that could leak some much needed info lol

lol i was gonna say ping pong was for s6/s6e only not note 4
[AT&T Samsung Galaxy Note 4] eklipz3:
Once this root stabilizes I wonder if simple reboot will also work on it?
[AT&T Samsung Galaxy Note 4] gatesjunior:
O.k., I am going to look into this.
[AT&T Samsung Galaxy Note 4] HotShotAzn:
Stupid question about temp root.

Do the changes made while in temp root stick? Or is it for session only? For example, if I used Titanium Backup to freeze an app while rooted, would the app become unfrozen once I rebooted? (albeit no more root)

I'm actually curious about apps that will link data files to my SD card...and to calibrate battery.
[AT&T Samsung Galaxy Note 4] raynan:
I actually froze a bunch of bloat this way. As far as I can tell, apps stay frozen after reboot/loss of root privileges.
[AT&T Samsung Galaxy Note 4] elliwigy:
extreme style haha nice to see youre still around old pal!
[AT&T Samsung Galaxy Note 4] raynan:
Hey, It's the best we got; I'll make it work :cowboy:. I'm sadly not planning on getting another Samsung through my carrier after this debacle. They're becoming too much like Apple for my taste :p
[AT&T Samsung Galaxy Note 4] elliwigy:
Same here actually haha.. I at least have full root on my s6e but im itching for an unlocked BL for sure so I will most likely go with an unlocked device.
[AT&T Samsung Galaxy Note 4] ZackFearheart:
All I really wanna do is root and remove bloat and tweak a few settings, and mess with some game files. But it seems like a temp root I am seeing will just make the phone super laggy and glitchy.
[AT&T Samsung Galaxy Note 4] Gods Son:
So I rooted my AT&T Note 4 today and I was so happy and overjoyed until my phone rebooted and unrootable itself.
[AT&T Samsung Galaxy Note 4] edjahman:
The temporary root is just a tease.
[AT&T Samsung Galaxy Note 4] Gods Son:
Well I know I can expect an update from AT&T soon. It's one thing I do know and that is that the lackies that get paid to scour sites and forums for any way to root the AT&T Note 4 variant are gonna make sure that this is patched immediately so they can get their change $$$

looks like he gets it to 4.4.4 then applies a kingroot apk for perm unlock. fingers crossed Im trying it.

EDIT: Update. The files for the Odin transfer are encrypted. havent been able to decrypt yet. Asked him for PW with google translation.
[AT&T Samsung Galaxy Note 4] elliwigy:
having trouble understanding what you mean lol the new root by yemen folks hasnt been released yet to my knowledge for N4
[AT&T Samsung Galaxy Note 4] Armorer2779:
anyone seen this?

I stumbled upon this website a lil bit ago while hunting free tethering software. its called oneclickroot.com and the actual page i found was supposedly for Note 4 AT&T. anyone seen this yet? I cant link the page due to having just been a forum troll on this thread for the last year and not ever posting before lol.
[AT&T Samsung Galaxy Note 4] DamnCampers:
I just checked out their page and looked at all the details they give for the note 4. I would be wary of the page as what they are promising, ie the ability to add a custom recovery, is not possible with our phone due to a locked bootloader. As it stands even if they could root our phone it will only be temporary as once we reboot our phone we go back to an unroot state.
[AT&T Samsung Galaxy Note 4] kxhan15:
I wonder if the bootloader could be unlocked if we knew the code and signature? If it can, I believe I know how to unlock the bootloader.
[AT&T Samsung Galaxy Note 4] howellcp:
Yes, if someone has the signature then it could be unlocked.
[AT&T Samsung Galaxy Note 4] kxhan15:
The question then is how? Since samsung devices don't support fastboot.
[AT&T Samsung Galaxy Note 4] howellcp:
The signed .tar file can be used in Odin. Beyond my skills by it can be done. Release the signature and it would happen. I doubt anyone actually has it.
[AT&T Samsung Galaxy Note 4] kxhan15:
Well I believe I have found the signature. See the attached image

Respectfully I am going to hold off on that because as I understand it, there is currently a sizable bounty for unlocking this devices bootloader
[AT&T Samsung Galaxy Note 4] howellcp:
I hear ya. I would do the same. Hopefully [MENTION=2376614]jcase[/MENTION] or [MENTION=3812611]elliwigy[/MENTION] can shed some light on what you found.
[AT&T Samsung Galaxy Note 4] dkmac:
I too believe that I have found the signature in addition too all system information from a dump that I got. There is defiantly a lot of information devulged within. I am hoping that a dev can use this to get what we need and hope that it will also lead to a unlocked bootloader.
[AT&T Samsung Galaxy Note 4] kxhan15:
I am going to try adb oem unlock (the signature I found) and see if that works. I am hoping it will work the same as the fastboot oem unlock way.

---------- Post added at 04:29 PM ---------- Previous post was at 04:26 PM ----------

The rest of this conversation should take place on Google hangouts as I am sure that the overlords at att and samsung are watching this now. Add me on Google hangouts.
[AT&T Samsung Galaxy Note 4] jcase:
its nothing of value
[AT&T Samsung Galaxy Note 4] dkmac:
[MENTION=3302422]howellcp[/MENTION], I would remove that image. I know exactly where you got it and if I know, Samsung and att will know as well just by looking at image. That is why I did not post any pics as well. Just looking out. Take care.
[AT&T Samsung Galaxy Note 4] elliwigy:
i highly doubt sammy would make the sig so easily available.. If one feels its the right sig then sign a tar with it and attempt to flash it..

i do not think that is whats needed but im not that good at dev work so i take [MENTION=2376614]jcase[/MENTION] word for it that its of no use.
[AT&T Samsung Galaxy Note 4] kxhan15:
Thank you for your input. Even though you say it is nothing of value, maybe you would be willing to tell us what it is. Because it checks that signature very early in the boot sequence, before anything else is loaded. When you read the full log it is a signature that is checked a couple of times early in the boot sequence. Everytime, the initial check fails then it loads that signature and verifies successfully
[AT&T Samsung Galaxy Note 4] jcase:
It is the public key used to validate something, probably one of the bootloaders of kernel/ramdisk images. Its not private/top secret, and not useful except for verifying that images were signed with the corresponding private key.

*Edit

Private keys used for signing firmware are absolutely never stored on a device (it would be stupid to do so, I mean technically its possible but this isnt the case, and its extremely unlikely. It would be some serious neglect to do so.).
[AT&T Samsung Galaxy Note 4] kxhan15:
So if the keys arent stored on the device, how would it verify? Especially in the case when there is no service or WiFi available. I'm just curious, but do you know where I got this from? If not, I would love to tell you.
[AT&T Samsung Galaxy Note 4] jcase:
You would verify with the public key, which is on the device, but useless for signing things. Sign with the private key (Which is not publicly available or on the device, hence private). Verify with the public key (Which isn't sensitive, hence not private, hence available).

No idea where that specific key is, I could probably grep through an emmc dump and find it trivially.
[AT&T Samsung Galaxy Note 4] kxhan15:
So why couldn't we use the public key in the same way.
[AT&T Samsung Galaxy Note 4] jcase:
https://www.youtube.com/watch?v=tnQ8lqzVMDo

Private key is for SIGNING images

Public key is for verifying images
[AT&T Samsung Galaxy Note 4] Android.Ninja:
jcase said it best, the key is most definitely not on the device or implemented from within the firmware itself. Doing so, would be a major security breach itself not to mention would defeat the purpose of the encrypted key to begin with.

The image that was displayed previously, can be located in several parameters on the device. One example, is booting into the maintenance menu & looking good at the logs there. You will find the "Public" key readily seen however the "Signed" encrypted & "Private" key would not be.

As I previously mentioned in the "Developers Only" thread months ago: LG devices utilize the "fastboot" command. With this command you can load all parts of the ROM separately and individually, via ADB and ADB command line. I've done this many times on many LG devices. However with the Samsung devices, you wouldn't be able to utilize "fastboot" to only overwrite the boot section or any other sections of the ROM, individual or not. >It's the communication process that takes place, via ADB that needs to be closely examined. This is what my team is working on and currently testing. There are very interesting areas in the communication process where DM Verity & the encryption decryption process communicate to validate the private protocol.

It would be literally impossible to get the private key validation sequence from the device. However, utilizing an exploit via keyboard etc, would be the most probable answer.

My team is still currently looking into several vulnerabilities and testing for possible permanent root possibilities. Keep in mind that I'm no jcase, lol. He's the man when it comes to Linux security, but we are giving it our best!

[AT&T Samsung Galaxy Note 4] kxhan15:
Thank you, you guys are all very helpful. But what would the purpose be of asymmetric key encryption if a public key did not check against a private key? for that matter what would the purpose be of having a public key without the private key to check why even have a public key? And I do know for sure that the phone uses asymmetric key encryption it says so right in the logs. So what pray tell does the public key check I know for sure / the logs that it checks because the log say that it verifies the public key
[AT&T Samsung Galaxy Note 4] kxhan15:
[MENTION=2376614]jcase[/MENTION] [MENTION=2260077]Android.Ninja[/MENTION] hypothetically if somebody new the private key code and the public key code could the bootloader be unlocked? And if someone knew the private key how would one go about applying that?
[AT&T Samsung Galaxy Note 4] jcase:
Whom is this team? Your post doesn't make sense.

You would take the key (which you cant get) and sign your modified image and flash it through download mode.
[AT&T Samsung Galaxy Note 4] kxhan15:
[MENTION=2376614]jcase[/MENTION] would you mind if I contacted you on Google Hangouts there's some things that I want to show you that I think really are quite pertinent to what we're talking about here.

what would need to occur to a modified aboot file, if it was signed improperly, but sent at the time of security check on the devices loading? Example fastboot on LG devices for reference. Any wisdom and help you can give would be greatly appreciated. Thanks.

[AT&T Samsung Galaxy Note 4] elliwigy:
youre still trying to figure that out?

i thought u were already past that lol.. Im sure odin would fail as well as it will not even allow you to change files once the process starts and it goes quickly as well so how would you even switch it out after a security check is done?
[AT&T Samsung Galaxy Note 4] ProJ0e:
All of this juicy talk of possible root has gotten me hitting the F5 and grabbing the popcorn o.o how can I prevent my phone from updating firmware without root?
[AT&T Samsung Galaxy Note 4] dkmac:
The same way that I did for the longest time. Max out the system memory and only leave about 800 MB free. Fortunately we still have SD card expansion available with theses.
[AT&T Samsung Galaxy Note 4] Android.Ninja:
Lol, no we're long past that. The reason why I ask jcase for his wisdom is because we already know that a modified aboot would not flash and would fail at the checkpoint, because the security signature (hash) would not be there. The thing is, the modifed aboot given to us by the Viet developer does flash, & without fail. Stay positive and keep quiet, that's the outlet were taking in till we discover full and permanent root. No drama here please, we're only trying to help out the Note 4 community.

elliwigy, jcase, hsbadr, gatesjunior, the list goes on & on; these are some of the brightest & most knowledgeable minds here on XDA. Please don't take offense, if I left any others out, there's just too many other devs to list. Our teams goal is one in the same. To give back to our community, regardless of the countless hours we put in for helping others with support issues, fixes, working arounds, and discoveries. Stay positive and stay motivated. That's what I strive for, even under duress from negativity. Root for the Note 4 XDA community has long been a uphill struggle with obstacles in every direction. Let's work together and root this thing, then split the bounty equally. ?

[AT&T Samsung Galaxy Note 4] Surge1223:
Even if you had a modified aboot, that someone was able to get miraculously signed with the Samsung Private key or Qualcomm dev key, it still doesn't help unless that aboot was for an engineering device (or changes the device into an engineering device), or was modified to remove the check on boot or recovery and the checks on whatever else the note 4 aboot checks.

What is the hwid and swid of this aboot? Showing us that info isn't compromising anything imho, I'd be curious to see its name as well. If you aren't sure how to get this information, it's trivial to obtain via writing a simple binary that parsers the header of aboot, or just using strings and grep.
