[AT&T Samsung Galaxy Note 4] ODSTZ3RO:
I know, the OP asks to open a file manager though.

Anyways, I lost root just as the other person that tried it before me did.

I'm greeted with "..kernal Panic Upload Mode.." after flashing pre-rooted LP, but

I'll be trying to flash the experimental firmware once I'm rooted again(as suggested earlier).
[AT&T Samsung Galaxy Note 4] AptLogic:
Did you use the firmware in the OP or the other one I put in the thread?
[AT&T Samsung Galaxy Note 4] ODSTZ3RO:
*delete*
[AT&T Samsung Galaxy Note 4] AptLogic:
No I mean did you use the pre-rooted LP that's 1.1GB or 1.9GB?
[AT&T Samsung Galaxy Note 4] :
You should retry with the 1.9Go Rom :V
[AT&T Samsung Galaxy Note 4] ODSTZ3RO:
Strange, I tried two pre-rooted LPs(1.9gb), but their krait info was different when my phone went to kernel panic mode.

Also, I some how got two experimental firmwares, one was from the OP and the second one was from the link you posted after. I later tried redownloading the one you posted after the OP, but it had switched to a 1.9gb file. Hmm, perhaps I could have also duplicated one experimental firmware zip. Regardless, I'm going to try the 1.1gb one(pre-rooted LP) and sorry for the confusion.
[AT&T Samsung Galaxy Note 4] nemopsp:
Has anyone been successful rooting this phone?

I'm not so sure what the engineering (experimental) software does but seem just puts the phone on 4.4.4 kitkat.

Looking at galaxy S5 forums you used towelroot because it got root an was make for it. Note 4 never worked with towelroot, your using what did work which was Kingroot then used SuperSUme to install SuperSU.

Which when my device was on originally on 4.4.4 NK3 it I've used this method an it worked but root would be lost within 10-20min because of DM-Verity in the kernel or it would freeze and reboot during SuperSUme.

Flashfire wouldn't work during thoses days either...

Wondering if it simular issues? Because I feel like it's not working because of DM-Verity. We have had root in the past just haven't been able to keep it. No one has found an exploit to disable it without a unlocked bootloader / custom kernel (with DM-Verity disabled)
[AT&T Samsung Galaxy Note 4] AptLogic:
The engineering firmwares usually have their SELinux set to permissive so that doesn't happen.
[AT&T Samsung Galaxy Note 4] ODSTZ3RO:
Neither worked
[AT&T Samsung Galaxy Note 4] AptLogic:
Okay I'll take a look at it tomorrow.
[AT&T Samsung Galaxy Note 4] marcimix:
Someone lost job in the AT&T?!

[AT&T Samsung Galaxy Note 4] HTC_Vivid:
Damn really hopes this work. Kinda tough to do it with a phone that's ~$400.

I just want to get the modded camera for higher quality photos and videos.

Good luck. You're doing more than most.
[AT&T Samsung Galaxy Note 4] boofman:
If that was the case, then I'm hoping we'll have a leak of the keys so we can unlock the bootloader and do whatever..
[AT&T Samsung Galaxy Note 4] chip707:
help!thanks to who ever is helpful in adavance

Hi,

Sorry to be a noob . I'm usually more knowledgeable in ios with jailbreaking. My wife has a samsung note 4 and just wants to get the phone running properly. The new update just causes her phone to act erratically with rebooting and shutting down by accessing the camera function. The phone also dies before the battery is at 0. Her phone model is sm-N910A ATT. Ive researched in these threads trying to make sense of andriod that this model has a bootlocker so rooting is almost nearly impossible at this point. But my question is anyway she can just downgrade the version of her phone back to a more stable operating system.

all phone info is as followed

android version

6.0.1

model

SM-N910

Also thank you for taking your time to read this .
[AT&T Samsung Galaxy Note 4] AptLogic:
She can downgrade to 5.0.2 with ODIN and the files in Post #2

Good luck :)
[AT&T Samsung Galaxy Note 4] ljjehl:
At this time, you probably need to Odin flash it back to 5.1.1 Lollipop. Battery lasts to the end there. I seem to have too many reboots when battery gets to 30-50% while in latest MM. Today I ran N910AUCU2DO12 all day today with data on and no reboots whatsoever, and battery is currently under 20% with no issues. Not sure what ATT did with MM, but I personally don't like it right now...
[AT&T Samsung Galaxy Note 4] chip707:
Is there a step by step guide with link? Thanks
[AT&T Samsung Galaxy Note 4] ljjehl:
I have this from a bit back, I used Odin 3.12 also.

[AT&T Samsung Galaxy Note 4] will5:
Thanks for this.

Yes, atm 5.0.1 is way better. The stupid battery problem is insane. If you charge through usb phone will keep losing his capacity to charge to 100%. It will charge to 8x% max. After some days, it will charge to 6x% max. And you have to do the stupid *#0228# trick and take out the battery to reach 100% again.

Wonder if they put some note 7 battery protection files by mistake on this MM build, it works horrible with all this battery problems. Phone not reaching 100% under many cirscunstances, feels like note 7 scary update.
[AT&T Samsung Galaxy Note 4] AptLogic:
Yeah this is why I'm not interested in making MM ROMs, battery life is horrible. Us 900A users are chilling here with new lollipop ROMs :)
[AT&T Samsung Galaxy Note 4] will5:
Nice :)

Not just horrible, it has many battery unresolved bugs also. Now im letting my phone charging all the night and it will stop charging at 64% This is not about fake or dying batteries, it s a bug.

Going back to lollipop as soon as I have some time. And will try root :laugh:

Thanks for all the work you are making here :D
[AT&T Samsung Galaxy Note 4] ljjehl:
Nougat is actually better if you are able to refine the kernel....I have better results with my N builds as opposed to previous MM. It seems that MM may be the bad apple, in between good versions....
[AT&T Samsung Galaxy Note 4] AptLogic:
Yeah let's just completely forget about 5.1.1 XD
[AT&T Samsung Galaxy Note 4] ljjehl:
You mean 6.x.x?? I'm currently on 5.1.1, hehe
[AT&T Samsung Galaxy Note 4] AptLogic:
No I mean slow, battery eating, lollipop 5.1.1
[AT&T Samsung Galaxy Note 4] ljjehl:
Hmm, never did compare that, but I know 5.1.1 was Def better than MM in battery
[AT&T Samsung Galaxy Note 4] chip707:
rocking the 5.0.1

so i was able to go back to 5.0.1 on sm-N910A version. My question is there anyway to go back to 4.4.4 kitkat?

also found this

"The Samsung Galaxy Note 4 originally shipped with Google's mobile operating system, Android, specifically KitKat 4.4.4, with its user interface modified with Samsung's custom skin named TouchWiz Nature UX 3.0. The Note 4 contains most of the original Note's software features and functions, but also adds more significant upgrades from the predecessors, such as a new multitasking interface, expanded S-Pen functions, gestures, and refreshed menus and icons.

The device can be updated to Android 5.0.1 Lollipop in many regions, bringing a new, refined UI, and new runtime. This version has been criticized for poor battery life. A further update to 5.1.1 is available, depending on the wireless carrier."- Wikipedia

After reading this whats the best firmware to have note 4 on? thanks sorry once again for my lacking knowledge of android phones

just trying to make my wife happy

cheers
[AT&T Samsung Galaxy Note 4] boofman:
I won't mind being stuck with MM as long as we have Root, and maybe a custom MM ROM and Kernel..
[AT&T Samsung Galaxy Note 4] ljjehl:
Even wondering if we can get root long enough to achieve this:

https://xdaforums.com/showthread.php?t=2447534&page=1141
[AT&T Samsung Galaxy Note 4] viewsfromthepi:
So when are the ROMs coming?
[AT&T Samsung Galaxy Note 4] boofman:
We have stock ROMs..we need to unlock the bootloader for custom ones..or maybe achieve root at least should be enough to circumvent that..
[AT&T Samsung Galaxy Note 4] Shanghai.Knight:
Am I missing something? From what I read, root is still not possible. Someone here tried root, but it didn't work, right? What am I missing?
[AT&T Samsung Galaxy Note 4] ljjehl:
It's temporary at this point. Apt is still working on getting a pre-rooted rom setup.
[AT&T Samsung Galaxy Note 4] mailjasons:
If I use this for even temp root! Do changes made durring root (removing bloatware) stick after reboot, even though I loose root after a reboot?
[AT&T Samsung Galaxy Note 4] nemopsp:
Well I never tired this method when I owned my N910A. Someone can correct me if I'm wrong, but as far of my knowledge after reboot nothing sticks because of "DM-Verity" and all bloatware will come back upon reboot.

This is what happened before when I used Kingroot + SuperSUme on 4.4.4 NK3 and 5.0.1 OC4

But this experimental software should change SELinux to Permissive according to AptLogic.
[AT&T Samsung Galaxy Note 4] AlexanderDAB:
I know I am asking something completely irrelevant to this post

But since this post has the engineered firmware as the main topic of this post

This is a good opportunity to ask someone from this post to help me and many others with the same problem as me

This has to do with bricked phones

You don't have to do this

This is completely voluntary

The AT&T Note 4 doesn't have an unbrick method if someone was trying to develop something that changes some things within the root files

And I was wondering if any of you could help me and some others with unbricking our phone

I was on this firmware when I was trying to mess with the DM-Vertification

and when I screwed up, my phone froze and when I pulled out the battery of the phone and tried to turn on the phone

My phone became completely unresponsive to turning on

I tried leaving my phone to charge for a few hours because it was at 20% when I was last on it

After 7 hours

It still would not turn on

The phone was even cold when I held it

I tried connecting it to my computer and when my computer recognized it

It was labeled as "Qualcomm HS-USB QDLoader 9008" and I knew this phone was hard-bricked because I installed this driver that recognized the phone when I hard-bricked my Galaxy S3 a while back

I tried everything to see if I could turn it

But everything was unsuccessful

I remembered that an unbricked image could potentially unbrick my phone

Only issue, the AT&T Note 4 does not have an unbrick image because there is no root access

But this firmware has so many root exploits

So I am asking you, if you want to, could use this firmware and run this batch file that I have linked below to make the unbrick image

1. Does this copy any personal information? No, this only targets the working aboot bootloader and turns it into an image file so it can read the aboot bootloader and go into download mode and flash a full firmware

2. What are the pre-requisites? Busybox (you can install it in an APK form) Kingroot for rooting, drivers so the phone is recognized by the computer, USB-Debugging enabled, and time

3. Is this a virus? No, this is not a virus

I even tried it out on an AT&T Samsung Galaxy S4 Active, My friend's Verizon Note 4, and my friend's Core Prime

And none of them actually did anything afterwards

4. What will this unbrick image do for the AT&T Note 4 community? I believe that it can help people get out of hard-bricks when they are trying to develop something

Like if the OP of this forum hard-bricks his Note 4

The OP could use the unbrick image to fix his phone and get it back up

Please help me create this unbrick image

I have new N910A on the way (eBay), will try to get that stock bootloader for ya, can I PM you in needed help?
[AT&T Samsung Galaxy Note 4] AlexanderDAB:
Yes you can
[AT&T Samsung Galaxy Note 4] kirbee213:
Wait, so this is (was?) a temp root? Can someone please clarify exactly what we have here for me?
[AT&T Samsung Galaxy Note 4] Shanghai.Knight:
Temp root....
[AT&T Samsung Galaxy Note 4] AptLogic:
At this point it's a temp root, nothing more. We seem to have selinux out of the way but when we try to flash a pre rooted ROM it boots into kernel panic.
[AT&T Samsung Galaxy Note 4] kirbee213:
That means that the loader is still locked under the rooted room correct?
[AT&T Samsung Galaxy Note 4] AptLogic:
Correct. For the most part it seems you face the same plight as the ATT S5 users in that regard.

But no dev-mode into Bootloader & bootloop, so any idea to modify source code of the exploit ?

http://github.com/beaups/SamsungCID
[AT&T Samsung Galaxy Note 4] AptLogic:
No because even if the exploit works you need to flash a developer edition aboot, which AT&T devices don't have (grrr)

Hi guys I got a question. I bought a N910A on eBay shipped overseas without evening researching its limitations and now I'm stuck with it. It came installed with 6.0.1 but the baseband version ends with eph7. Will I still be able to downgrade to 5.x using the file from post #2? Thanks.

Yes, you can downgrade to 5.x from every 6.0.1

[AT&T Samsung Galaxy Note 4] viewsfromthepi:
Whats the link so i can distribute the image to root communities
[AT&T Samsung Galaxy Note 4] matezz:
Sorry to disappoint, the root is required to get this unbrick image, but KingRoot wasn't working for me too well. Every time KR said root successful, root checker or others reported that there was no root :mad:. Soon after phone rebooted. So I have given up on N910A and switched it for N910T.
[AT&T Samsung Galaxy Note 4] ProdiJoe:
Would it be possible to make the N910a believe it's a Verizon instead of att? I mean it's the exact same hardware right?
[AT&T Samsung Galaxy Note 4] AptLogic:
No because

1. I tried that on an S5 and almost permanently hard bricked it.

2. You still need root to do that

Sorry, it just won't work :(

How do I flash back to stock if there is no download mode?

I don't know if it helps but I still have the NK3 firmware for the AT&T Note 4

https://drive.google.com/folderview?id=0B_jNvp2vyz2xQnZQZ3VsNWJ1bU0

Download it if you need it, I was about to delete it from my GD, I'll leave it there for a few days... Good luck guys!
[AT&T Samsung Galaxy Note 4] bobshmo:
Thanks for the help but I ended up figuring out how to get to download mode, I had to run adb and have it reboot the phone in download mode. I then flashed the phone with the stock firmware the creator of the root method provided.
[AT&T Samsung Galaxy Note 4] ProdiJoe:
I know there isn't a developers edition for att but... Is there even a slight chance we can change the Verizon developer edition to match almost everything that a stock N910A checks for? I mean it is a developer edition so we should be able to change everything we want right?
[AT&T Samsung Galaxy Note 4] AptLogic:
No because if we modify the dev aboot for Verizon it'll break Samsung's certificate and it wouldn't work anyway.

[AT&T Samsung Galaxy Note 4] AptLogic:
Yeah you can't go back to KitKat, sorry :/.

You're not missing out on too much. The battery life on 5.0 is about the same as KitKat was (on my S5 anyway).
[AT&T Samsung Galaxy Note 4] Zwillmaster1:
So will there ever be a way to flash the pre rooted oc6 and successfully boot? Why can't we just flash it in Odin? BTW Thank you soon much for the experimental firmware it let me downgrade to 5.0.1 which is way less laggy and battery seems better then 5.1 and 6.0
[AT&T Samsung Galaxy Note 4] bhd_guy:
Thanks for the tip! Somehow I feel that I'd be having a N910T before root ever happens on the N910A lol. It's funny but I just can't stand NOT having root. Every other device I've had is rooted. It pisses me off when I don't have control over my phone.
[AT&T Samsung Galaxy Note 4] UbuntuPC:
But do the devices know that?

It would certainly appear that every other version of this phone has either a developer or engineer edition.

Oddly enough I was looking forward to this with my N900A, but I traded it for the N910A. :(
[AT&T Samsung Galaxy Note 4] Zwillmaster1:
Successfull temp root coc6

Not sure if you guys where aware but iroot will temp root n910a on coc6 just tried it myself

can i remove iroot with supersume?
[AT&T Samsung Galaxy Note 4] Vybze:
Is the root stable?
[AT&T Samsung Galaxy Note 4] Zwillmaster1:
not sure how stable it is it completely disabled my Samsung keyboard. it said I was rooted and and it granted root permission to the iroot app. everything was perfectly fine except the keyboard. I transferred root checker from my pc to make sure I was actually rooted. I was then I tried to open the king root app that iroot had installed during the root process and it said that root needed to be repaired so I let it try to let it replace iroot because I wasn't sure if iroot would work with supersume but the king root failed. then i opened the iroot app again and it said I wasn't rooted so I tried again and it failed and rebooted. then I just removed the app.

i am rooted yay lol
[AT&T Samsung Galaxy Note 4] UbuntuPC:
Following the guide from the OP?

EDIT: Following my comment I flashed the experimental firmware and dicked around with it. I didn't have anything besides hardware tests and such, so I couldn't install any apps. I did, however, notice that we can get low, mid and high logs. I also found out that the base model for this particular model is the F variant, so there's hope.

I'm going to poke around some more when I'm done getting this rooted.
[AT&T Samsung Galaxy Note 4] Zwillmaster1:
Actually I just used the experimental firmware to downgrade to coc 6, then I just downloaded the latest kingroot apk and It worked.
[AT&T Samsung Galaxy Note 4] UbuntuPC:
Coolbeanz. Over the night I tried the PC based kingroot, which told me it achieved root, but had not, followed by the kingroot in the OP, which had better success to the point of turning off DM-verity. Then the phone reboot, progress was lost and SuperSUMe broke.

Trying your method.

UPDATE: I've tried several different methods without verifiable success. Continuing to try different methods.

I do have a question, however. Where is the BL actually located? On the NAND chip? Or the Qualcomm chip? Thinking of erasing and flashing the N910F variant.
[AT&T Samsung Galaxy Note 4] ODSTZ3RO:
How long did that last?
[AT&T Samsung Galaxy Note 4] UbuntuPC:
I have an interesting problem at the moment. My test tells me it's constantly waiting on CP Bootup, and bootloops within a minute. When I do a full flash of OC6 it will reboot about 46 apps into the 248 app optimization. Is there a fix you can think of, AptLogic?

Update: I ended up fixing it by turning off the CP logging popup. Update: It persists after reboot.

I have finally has success with your method up to installing apps (I did it through adb install), rooting and launching supersume to attain superuser. However, SuperSU has not asked me to update binaries, so I'm not sure if I want to go through the task of redoing firmware flashing and whatnot without confirmation.

I did reboot the phone, at which point SuperSU does ask for binary install, but I don't have root at that point and have to redo the process. Kinda stuck.

My problem with my phone, while on the eng boot, (with current CP problem) is that it vibrates it's messages. 3 short, 1 long. 3 short. 2 short, slightly spaced. slightly random as to which happens at what time.
[AT&T Samsung Galaxy Note 4] Zeal415:
what file manager? I got the APK's on my SD, with the firmware loaded, im not seeing any explorers.

That Rollback sends us back to what androud version 5.0.1?
[AT&T Samsung Galaxy Note 4] UbuntuPC:
The filemanager doesn't exist, you'll have to adb them to the phone.

adb devices - to see if your phone is connected properly. Next, navigate to the folder your apks are installed, for me, Documents.

adb install Kingroot.apk

adb install SuperSume6.7.apk

adb install flashfire.apk

They will auto install.

Next, hook upto Wi-Fi and run Kingroot.

Go from there. I did notice that SuperSU doesn't ask me to update binaries, and when it does it fails.
[AT&T Samsung Galaxy Note 4] Zeal415:
Yea I just sideloaded the apks. Bout to run the Flash, SuperSU did not ask to update the binaries, hoping this works, I locked my phone and disabled the samsung account so its asking for a ghost samsung account now. idk if this will enable me to bypass it, im thinking even if im rooted im going to need a custom rom that disables samsung account to access the phone.

Edit: I am consistently getting Kernel panic on the flash, that's with a wipe. 5 attempts so far.
[AT&T Samsung Galaxy Note 4] UbuntuPC:
I had multiple problems with that as well until I updated my phone with a full factory flash with ODIN 4-file restore.
[AT&T Samsung Galaxy Note 4] Zeal415:
Did you flash the restore than do factory reset through android?

My problem is that my phone is locked through samsung, so i am trying to root it and bypass the samsung lock, then register my phone with samsung, so i can use it again, or even just sell it. At this point its not looking good. Imma give it a shot with factory reset through the recovery.
[AT&T Samsung Galaxy Note 4] UbuntuPC:
A frp lock will not go away with a recovery wipe. That's the whole point behind it. It stands for Factory Reset Protection.

I may be able to help. What is the phone model and firmware?
[AT&T Samsung Galaxy Note 4] Zeal415:
I am on SM-N910A, with what ever firmware that rollback was. Thats where I am at, not sure if I can upgrade or downgrade. I was hoping I could use the root to bypass the lock, register the phone than go back to regular firmware and load up the now registered phone.

Honestly at the end of the day I am just selling it anyways, I'd just prefer to get top dollar for it because I just got the S8+
[AT&T Samsung Galaxy Note 4] ODSTZ3RO:
*sigh* I wish it wasn't temp root. Anyways, do you get kernel panic mode when you reboot?
[AT&T Samsung Galaxy Note 4] UbuntuPC:
Yup.
