I just picked up a used T817T yesterday. I was able to root it with Kingroot. I then found out that I lose root after a reboot. Even worse, without enabling the developer options and enabling the OEM unlock, it would no longer boot. I had to reflash the stock ROM with ODIN to recover.
I purchased and installed SuperSu Me-Pro and that replaced the Kingroot SU with SuperSu. Now I can reboot without losing root.
I'm being prompted to install an update T817TUVS2APB1/T817TTMB2APB1/T817TUVS2APB1. If I install this update, will I lose root? If I install it, can I still root with other methods?
I still have the stock recovery.
I'm currently on T817TUVS2AOL1.
I decided to roll the dice and try the update. I got a message that the software on my device was altered in an unapproved way and that it would not update. At least the nagging icon on the top of the screen is now gone.

Install it with Flashfire.

When I purchased my Droid Maxx it was running 4.2.2 and I used the PIE exploit to root it. At the time, I didn't realize that allowing the 4.4.4 OTA update would completely frag the root so I took it. Now, on 4.4.4 I of course have very buggy and inconsistent root access. So, I decided to just unroot and forget about it for this phone. To that end, I ran a full unroot from SuperSU and the app disappeared. Great...until I rebooted and it came back. I went back into the app, disabled it via the app settings, full unroot again, and again the app reappears on reboot. I can't delete the apk from the System folder because even with SuperSU enabled it won't grant me write access (see above: root fragged). So what the hell am I supposed to do? The phone is essentially unrooted, but on every reboot, regardless of unroot attempts, SuperSU reinstalls itself.
Any ideas on how to get rid of it?
Either root it properly and use that to remove it, or reflash your full stock firmware.
Last night I went to open Titanium Backup and was notified that I didn't have root. I've been rooted with ioroot for over a year now without issues. Root Checker app confirmes root was lost. SuperSu gave binaries error.
HOWEVER, in About Phone > System Status it was still showing as 'Rooted'. I'm still on 4.2.2 / VS98011A. All I've done is update the same ol' apps I've had for months.
What gives? Anybody have any ideas why this would happen?
The only thing I can think of is when SuperSu updated recently it asked to use TWRP (instead of the 'normal' method) to run a script to update binaries which I obliged. It seemed to struggle with that.
Anyway, I did use TowelRoot this time since I was too lazy to refresh my memory on the ioroot process. It worked fine however I've had a few random locks and a random reboot. I never had those issues before.
Any insight would be appreciated.

Do you have TWRP installed? If so try to get it to reflash the binaries again.

After rerooting with towelroot, i uninstalled SuperSu. Then reinstalled SuperSu and choose install binaries via 'normal' method. That appears to have worked fine.
My question relates to why did I lose su/root functionality in the first place? Is this known to happen sometimes with app updates, (not just system/os/ota updates)? That has me concerned.

I would assume not installing the SuperSU binary updates correctly broke SuperSU. You didn't lose root per say, you broke SuperSU which apps need to be able to run as root.
I recently used the "New Root Method For 5.1.1 w/o custom kernel" to root my otherwise stock Note4 SM-N910T.
Everything was fine, but after a few weeks I lost root. I was able to get it back by re-flashing SuperSU 2.65 from recovery.
After further research, I found the blog post by Chainfire on SuperSU 2.74, and understand that 2.74 addresses the Samsung security update.
I've been using "SuperSU 2.65 Stable" because of root access compatibility issues with some programs.
How do I know if the Security Policy update was the cause of losing root? My phone's About Device has "Android Security Patch level" as 2015-11-01. So it doesn't look like something that was updated in the last week.
If it was not the security policy, then what caused the loss of root?
I have automatic updates off, and did not update anything at the time I lost root. Is there any other way that an update or change can be pushed? My /data/security/spota folder is empty. Should I delete the empty folder just to be sure?
I guess because you upgraded the system root cause failure，you need to flash supersu.zip again ，can retrieve root

Here's a summary of the problem:
1) FlashSuperSU from recovery.
2) Enjoy Root
3) 1 to 3 weeks later - something disables SuperSU, and root is lost
4) Go to 1)
I want to understand what is happening in 3) so I can exit this annoying loop.

This has only happened once? Interestingly, I had the same exact issue happen to me on my S5 with MM, I rooted using chainfire and just out of the blue, all root privelages were dismissed. So I flashed SuperSU v2.65. It happened multiple occasions until I was able to switch to an AOSP ROM. After going completely custom it seemed to have stop doing this. Maybe because of a contrast of coding that differ in security.
Sent from my SM-G900P using XDA-Developers mobile app
It has happened twice. I'm working on a Tasker recipe that will check for root regularly and report when it is lost.
Now it has happened three times. Still trying to figure out what causes it. I have not found a tasker function that checks for root.
Unless I can find a solution, I guess I'll have to go back to the traditional root with beastmode kernel.

Nobody seems to have any idea what's going on. I'm guessing the loss of root was specific to SuperSU 2.65.
Here what I've tried today:
1) Recovery / Flash with SuperSU 2.65 to get root back.
2) Update SuperSU Pro to 2.76 from Google Store. Download and copy ZIP to phone storage just in case.
3) reboot and verify root still available from Titanium Backup
4) Uninstall ES File Explorer Pro. Install Solid Explorer
5) Test root access of Solid Explorer. It works. Buy Solid Explorer.
6) reboot again just to be sure root remains
7) Backup with TB.
So far, everything is working. Hopefully it will remain rooted.
Almost 3 weeks, and no loss of root. Super SU 2.76 seems to fix the problem.
J500G lost root minutes after connected to internet. I have to root every single day.
I just got a new Fire 7" 5gen, with Fire OS 5.3.1. I immediately used Supertool to root it and install the CM ROM.
So far so good.
But not realising how CM deals with root access, I manually installed SuperSU. SuperSU wanted to update the binary, which I accepted. It also wanted to remove the existing root manager, which I also accepted... And then the binary update failed.
It's only then I realised that I somehow ended up with a custom ROM but no root. Neither SuperSU nor Superuser can get root access (both failing binary update), and Kingroot can't root it either. I'd have just flash CM again, but FlashFire also doesn't work without root. So I'm kind of stuck now...
Any idea how I can get root?
Just realised that I had to turn on root in Dev options. I did that and rebooted, but Super SU still fails to update the binary. FlashFire now says "Root was found but access could not be acquired".
Make sure you did reboot after root activation in dev options
Yes, as I said, I already rebooted. Any other idea?

At this point your best/only option is to reload FireOS via Amazon's stock recovery (same version as before) and redo root, Flashfire, etc. There is no reliable way to secure root on a custom rom as device lacks access to a 'real' recovery environment. Don't bother with KingRoot on CM - likely won't work.

Yeah, I did the whole thing from zero again. Happily it worked this time. Thanks!
I am buying a unlocked note8. And I require root as a lot of my apps require it.... and it’s my understanding that I am going to need to stop the ota update in order to achieve root.
Can someone please tell me how to stop the ota update so I can root the device.
Hello,
Curious if are you going to run a custom rom or root and remove apps you don't want?

Which model do you have? Snapdragon?
Generally you can disable the software update using a Package Disabler from the Play Store, or freeze it using Titanium Backup once rooted. Simply turning off the update option in Settings will not work long-term, as it would eventually update anyways. That's why you need to disable or freeze it.
In developers options you can also turn off auto update system. Usually after you root OTA updates won't function anymore anyway after the device status changes to custom. Or does that not apply for US Snapdragons & SamFail?
Can I temporarily disable it just long enough so I can root. Via samfail
Yes, just go in settings - software updates, there change to download updates manually... Job done: nothing will be updated unless you initiate it yourself...
Can update be stopped without root?
Most package disablers are not working,dev option not working.
Have gone back to oreo from pie don't want be forced back onto pie.
I have a rooted Galaxy s10+ with android pie. Doesn't freezing "Software Update" system apps of my android by Titanium Backup make booting problems for my device? Is it safe for me to freeze those apps? I ask because I've heard freezing some system apps like "Device Care" stops the device from booting. As other fellas I get ota update notifications and I wanna get rid of them by freezing those apps.

I am disabling apps with a package disabler for them to still keep updating! So I have gone back to the method of disabling apps via ADB (no root needed this way)
It uninstalls it for the current user, but a factory reset will bring the app back if so needed. You can uninstall the update app with this method, or any other app for that matter. (Just be careful with what you disable)
