Background: I had updated to OA1 4.4.4 on s5 900A. I had some issues, so I decided to downgrade as described in the upgrade thread here: http://forum.xda-developers.com/att...to-root-g900aucu2aoa1-4-4-4-2-3-2015-t3021120.
I would downgrade by flashing in odin the G900A_Downgrade_to_NCE.tar, as well as the G900A_ND3_Stock_Kernel, rerooting with towelroot, installing safestrap, and flashing one of the many 4.4.2 roms.
However, upon boot all of the 4.4.2 roms would be laggy, I would sometimes get a green/pixilated effect on the lockscreen when unlocking, and battery life would be sub par. I came across this app on play store:https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo&hl=en , and even though I had downgraded the kernel, the bootloader read as OA1, even after flashing in Odin the ND3 stock kernel.
I believed that was causing the issues I was having, and was under the impression that the bootloader could not be downgraded. In a fit of frustration I did the following, and fixed the problem!
Solution:
This is not a step by step, but a rough approximation of what I did, if you need more detail, just ask.
1. I downloaded and put on my SD card G900A_NCE_to_NG3_OTA.zip https://www.androidfilehost.com/?fid=95916177934525665
2. In odin 3.09 I flashed G900A_Downgrade_to_NCE.tar https://www.androidfilehost.com/?fid=23622183712464416,
3. Also in the AP slot I flashed G900A_ND3_Stock_Kernel https://www.androidfilehost.com/?fid=23622183712464356
3. My phone was unrooted at this time. I let it boot up, downloaded the Phone INFO ★Samsung★ to the phone from the playstore, opened and my bootloader remained OA1. The camera was normal, and the boot was slow, so I was where I was many times before.
4. I shut down the phone, I rebooted holding volume up, power and start until I got to the standard, built in samsung recovery.
5. I located my download of G900A_NCE_to_NG3_OTA.zip, and flashed it via the samsung recovery. It took about 5 minutes.
6. The phone rebooted, and the phone info app said I had and NG3 baseband! It had downgraded! However, towel root was not compatible.
7. I flashed in odin G900A_ND3_Stock_Kernel again. Now towelroot rooted the phone. I installed busybox and superuser from the playstore, then safestrap again.
Now I can flash any of the 4.4.2 roms, none of the slowbooting, stuttering lockscreen or battery issues seem to be present, and Phone INFO ★Samsung★ has my baseband and bootloader as NG3.
All credit goes to muniz_ri, these are all his tools! I just stumbled across this method and thought others might benefit.
I can confirm this.
I was on OA1 after flashing OA1 OTA zip from recovery.
Later, I downgraded by flashing G900A_Downgrade_to_NCE.tar. Bootloader after this was OA1.
Flashed G900A_NCE_to_NG3_OTA.zip from recovery. Bootloader and baseband changed to NG3.
Bootloader and Baseband version was verified using 'phone info' app from play store.

Likewise, just did it, I found with me, the OTA zip file would not install with the ND3 kernel installed. So I did the original odin downgrade to NCE, booted, then the OTA zip file, booted, Then the ND3 kernel Tar file in odin. Worked .Good luck:good:
so the nce to ng3 downgrade goes in the ap or BL?

was on Muniz 5.0, downgraded to xtreme dynamic kitkat. Still had oa1 bootloader, and was laggin really bad on boot.
Flashed this in stock recovery (wipes data part ) and reloaded my apps.
All seems to be well, without the need to go back to stock in between.
Thank you - this totally worked for me and got rid of the lag in my 4.4.2 ROM (XDK) as I had taken the upgrade to 4.4.4 way back when!
Hi,
do you do step 2 & 3 at the same time?
which field in Odin do you put the .tar file?
Thanks,

I'm not sure. Sounds like the reactivation was locked before you downgraded. I'm not sure how to fix that.
I was running stock rooted Lollipop ....Wanted to try out a new rom so when I tried to reboot to TWRP nothing happened...So I decided to just reflash TWRP via Odin and it failed...tried to reflash cf auto root via Odin and failed. I was able to flash the NK4 firmware via Odin. And same fail message came up for Cf Auto Root and TWRP...Went to check recovery and I'm back to stock. Tried doing a factory reset in stock recovery and failed...preload destination does not exist! Fudge bananas! So I flashed the firmware (OC6). It's working fine but I can not use Cf Auto root nor flash TWRP via Odin....Any ideas what's going on?

Perhaps you don't have the latest versions of cf-autroot. odin and twrp recovery.
The latest versions are twrp v2.8.6.0, odin v3.10.0 and cf-autoroot.
Both twrp and cf-autoroot are specifically for the N910T Tmobile Note 4.
Here is a direct download link to the latest versions:
https://www.dropbox.com/s/i25yjb1o97o96nb/CF-Autoroot & TWRP v2.8.6.0 and ODIN3 v3.10.0.zip?dl=0
p.s. Be sure to use the original Note 4 charging cable.
Good luck!

I'm using the same files as I did Monday when I initially went to Lollipop on Monday. I was on stock rooted Lollipop.
I can flash firmwares without errors, it's cf auto root and twrp that fail.

I just looked at your two screen shots and noticed that your activation
lock is ON, so go into settings>security and turn it OFF.
Then power off the phone and go into download
mode and start odin flashing cf-autoroot and twrp.
Good luck!
Your lock ? is defintley your issue. I still using twrp 2.8.4 with no issues and odin 3.9.

Geez that sounds right. Forgot I turned that on when installed Lollipop. Can't wait till I get home to change that back. Thanks my friend!
Thanks
Home from work and I ran to my computer! That''s exactly what was wrong. I'm rooted again and flashed TWRP with no issues. Thanks again guys!
If you decide to download the AU ROM for N910G (which works great for other regions), you can easily root it by flashing the permissive kernel for the N910F.
AU ROM thread - http://forum.xda-developers.com/note-4/general/sm-n910g-lollipop-5-1-1-released-t3215823
N910F kernel thread - http://forum.xda-developers.com/note-4/snapdragon-dev/kernel-5-1-1-selinux-enforcing-t3190799
So in short:
Download the ROM and flash via Odin.
Download the latest TWRP and flash via Odin. It will also install SuperSU.
Flash the kernel via TWRP (ensure you copy it to your external SD in advance).
That's all! You end up with a rooted N910G that is smooth and a far cry from the laggy monster that was 5.0.1!
Worked great! Thanks!!
Works perfect on 910G thanks.
Is it true that after flashing TWRP, when the phone switches off & on, quickly press 'buttons' for recovery and flash the new 2.49 SuperSU app.zip instead of letting TWRP install it as TWRP installs an old superSU & is outdated... ??

You can always flash the latest or update SuperSU anytime.

I presume this still trips knox?
Those who have warranty and don't want to trip knox, I don't think there is any root method available. All root methods trip knox and hence warranty issue, for those who don't have warranty they can forget knox.
Warranty doesn't concern me, I use the phone for work and tripping Knox would stop the phone working on the work network.
But it sounds like this will trip it, so yeah I'm not going to.
Thanks though.

Root N910G
Hey,
I've searched everywhere, most of us aren't able to root since the link for the kernel is not working. Is there any other way to get root on N910G? :fingers-crossed:
"Recovery is NOT SEANDROID ENFORCING" after CF-Odin rooting N910T3 run on M6.01
Just got a US Cellular Galaxy Note 4 phone. Did a factory reset and it run perfectly on T Mobile N910T3 Marshmallow 6.01 (stock). Must have been rooted before, but flashed back to stock firmware and unrooted. So I want to get it rooted again.
Without realizing the difference of rooting androids running on Marshmallow and previous versions, I downloaded the latest specific CF-Odin tool for N910T3, run it to root it. Quickly, Odin showed the green "Pass!" But the phone got stuck immediately after that when it proceeded to reboot with this error:
Recovery is NOT SEANDROID ENFORCING
Set Warrenty Bit : recovery
And the Galaxy Note 4 logo.
I removed the battery, waited for many minutes or a day. Power it on or boot to Recovery Mode always get to the above same error, so I cannot wipe data or do factory reset, as some suggested.
From above error screen, hold Volume down+Power+Home, I can easily get to the Download Mode. So I downloaded N910T3UVS2EPE2 (not the latest N910T3UVS2EPG2, as it's too slow from Samsung), but failed to flash it with Odin (3.11.1 or 3.10.6) with or without PC's Antivirus Off. And on the phone I got:
SW REV CHEKC FAIL : [aboot]Fused 2 . Binary 1
[1]eMMC write fail: ABOOT
Wonder if I can flash TWRP with Odin in such a state? Besides, I forgot and didn't install USB drivers for Galaxy Note 4. Could this be the problem? I have USB drivers for Note 2, and it seems the PC communicate normally with this Note 4.
Appreciate very much for any help!
Having the same issue. Can't even get the phone to flash the pit file or the stock software it fails every time.
Think the phone is Toast.
***Update***
Had to do some weird stuff to get it booted and running stock un rooted again. I ODIN flashed TWRP booted into recovery and formatted DATA, then I ODIN flashed the GP2 PIT file along with the newest version of the CF Auto Root at the same time (For some reason this is the only way the PIT flash would not fail, Then I ODIN flashed the [email protected] stock firmware, and it finally booted again. After not being able to boot for 2 weeks. Device is running the setup now.
Update:
I was too scare to take any actions on the phone for almost a week! However, yesterday I only flashed TWRP with Odin and it automatically rebooted back to normal!! Everything seems to be working perfectly again! The only exception when I boot it to recovery mode to TWRP, I still see a flash of the following error message before TWRP:
Recovery is NOT SEANDROID ENFORCING
Set Warrenty Bit : recovery
Some how TWRP can pass the bootloop.
With TWRP I was able to root the phone, thanks to Rootmygalaxy.net, and did some backups.
Wonder if I can get rid of that error message by wiping Cache/data...?
You will get an error on that screen; kernel error or not seandroid enforcing error because it is not Samsung stock being used. There's no getting g around the warning that I'm aware of and it doesn't cause a difference on the phone running stock modified or just going all out and running any other rom.
New 6.0.1 and 7.0 root coming soon!
Back again as promised.
Required files:
-G925v OG7 Eng tar : (new Eng boot with faster bootup and stability improvement, reflash if you used the older version)
https:// mega dot nz/#!wJVmkJ7R!pWBoxloXf7m8PXGhGwkh_mfcFiIK-zAbioNs2Nbxszs
-Kingroot apk (king not kingo!)
Kingroot dot net
-Odin
Steps:
Run odin
Put phone in download mode
Add the tar to "AP" and click start
Device will reboot with new green writting on top left (ignore it)
Run Kingroot and click "try root"
It will be slow and lag around 16%, be patient and try to keep the screen from turning off. At 34% it will blast off to 100 and ull have root!
Enjoy
Recomended:
Have kingroot disable "knox"
Download root uninstaller and freeze "securitylogagent" to get rid of that annoying "unauthorized changes" message.
NOTE: This is TEMP root, youll have to repeat the process after every reboot to regain root.
NOTE TO DEVS: unpacking the boot image and modifying the ramdisk and trying to get permanent is an option, but DONT repack and flash with odin, it will cause dm-verity check to fail. Instead transfer the new boot.img to the phone and flash with flashify. I tested it and it seems to not cause a check failure.
New 6.0.1 and 7.0 root coming soon!

Thanks..
Confirmed working great on 5.1.1 my phone is rooted and boot time is faster and you can use hot boot to reboot without loosing root.
Are there any advances/news on a permanent root method on Lollipop 5.1.1 or on Marshmallow or Nougat? It would be great if there was a way to not have to re-root the phone every time it is turned on... I'm really thankful for your work!
Thank you !!!

Hi and thanks for the tutorial! I followed the steps and successfully completed the odin part. However, my phone will not load past the Samsung Galaxy S6 edge page. There is the green writing on the top right hand. Do you know how I can fix it?
Looks like everything works! Now off to find a 6.0.1 root...
Hi, I followed your tut on downgrading my SM-G925V to 5.1.1 and also got root which was great, but I guess its pretty worthless as its only temporary til reboot, has there been any further progress on permanent root on the G925v? Great work btw
