[Q] Restore Lost root?

I somehow lost root on my tf300t, stock Android 4.2.1 build US_epad-10.6.1.27.5, locked bootloader. Root Checker Pro shows the attached info.
It appears permissions are messed up? I, don't know how, I have both Supersu and Superuser installed.
Is there a way to restore root using ADB? Or do I need to re-root somehow?

[Q] Rooted but no Root access

Hi every one,
I currently am using an LG G2 from tmobile (801 model). My device says its rooted but it doesnt have root access because I forgot to flash supersu binaries before i flashed the 4.4.2 version of the software. But now my custom recovery doesnt exist anymore.
I've tried using LG flash tools to flash back to 4.2. stock settings to start over but I am unable to do so for some reason. LG Flash tools isnt able to recognize my G2 in download mode. My computer is able to recognize my G2 when it is turned on though.
So is there anyway to flash a custom recovery without root access?
Or is there anyway to flash supersu binaries without a custom recovery using ADB?
I've tried trouble shooting with multiple threads and multiple downgrade methods but none of them are giving me any luck. I really want to flash a custom rom on my LG g2 and have the benefits of root access.
Any help would be greatly appreciated.

All you need to do is install the towelroot.apk to give instant temporary root. Then install SuperSU from the dev thread here on xda or from the play store. After installing SuperSU go to its settings and select install as a system app and reboot when finished. It might take 2 attempts before it successful (it always takes me 2 tries). Then uninstall towelroot as it's no longer required since you've gained permanent root. Now install the autorec.apk and you'll install TWRP recovery. Now that you have root and recovery and have control of your device you can customise to taste. In my case I always install busybox and a terminal emulator so I can further fine tune my system.
I hope this helps
Ciao

still got issues :/

However even when i go into supersu, it keeps saying my binaries are not up to date. So i cant install anything and I cant do anything to install a custom recovery without root access.

So you have installed Towelroot, achieved root then having issues installing the SuperSU.apk this is indeed an issue. Towelroot should allow for it to be installed. When you install Towelroot do you get the warnings from the installer and Lookout that the package contains an exploit? Do you interrupt or stop it from fully installing when you see the warnings? The only thing I can think of is you are doing something wrong when installing towelroot which is prohibiting it from doing its job in gaining root.

Lost root access after installing Magisk! Cannot install SU!

Earlier today i noticed i could not play super mario run because the game checks for root access. After trying it and failing, i decided to install magisk to cover up root. Booted in to TWRP Recovery and flashed magisk and rebooted. When prompted to install SU i accidently hit do not install and now the SU app keeps telling me to install SU. I tried updating the app and it tells me Su binary occupied. If i uninstall it it tells me that i need to update the binary then fails when i try it. Already tried flashing the update of SU through recovery and nothing. Tried removing all root access and it will not get removed. Even tried to root all over again through odin and still having the same issue. All root access apps tell me im not rooted. Anything i can try without getting rid of my apps and data? Only thing im thinking will be to fully unroot and install stock rom and wipe all data.
Im on a galaxy s5 from sprint, running stock deodexed rom 5.0 lollipop.

Its been a while since I used Magisk. But at that time, PHH superuser had to be used?? Not sure if that is still the case though. Sorry I could not be more help

Yes it does need to be used and it was already installed. But after rebooting the app was not in my app drawer and i had a notification to install SU through play store. But when i go to play store it says it is installed and needs an update. After updating it tells me su binary occupied and takes me to a page to help fix it but i already tried flashing superuser zip file through recovery and nothing changes

Similar Problem
Have you fixed it already because I am havibf the same problem here. I am usibg Samsung J7 Core

You can do what you said you would do (reinstall stock ROM) and then you can try again. Looks like thats the only thing you can do, unless you can somehow remove the root binary and the app using something like ES File Explorer (but again, it requires root) or you can try another root provider.

Root checker showing device as rooted, but not able to utilize root capabilities?

I'm using a T-Mobile Galaxy S7 SM-G930T. I rooted the phone (or so I thought) using ODIN per Max Lee's guide. I have been unable to get SuperSU to work, so I removed that and downloaded phh's Superuser from the Play Store. I have Root Checker installed which tells me phone is rooted. Whenever I try to use apps that require root access (Busybox, Titanium Backup, and Greenify), I'm told that the apps don't have root access. I can't seem to find any way to grant any apps root access with phh's Superuser, nor was I able to find a way to do so with SuperSU. I also attempted to flash stock firmware back on to my device to unroot it via ODIN, but that failed as well. I can't seem to unroot my device, nor can I utilize root capabilites. I'm stuck in some kind of limbo and I don't know where to go. Can somebody help me solve my root issues or unroot the device altogether if the first option doesn't work?

What version of Android are you on? From what I remember Max Lee had an outdated engboot.
---------- Post added at 04:43 PM ---------- Previous post was at 04:40 PM ----------
If you are on nougat download and use the adb root files in this thread https://forum.xda-developers.com/tmobile-galaxy-s7/development/rom-t3636434
Inside the adb root folder there should be an updated eng boot that you can flash through Odin.

Help rooting Samsung Tab A

I'm new here so I'm not sure if this is the right place for this, but here goes. I've been trying to root my '19 Galaxy Tab A T290 [T290XXU3CUF8] for a couple months now on and off. I manage to get a success message from Odin when flashing TWRP but when I try to reboot into it, it goes straight back to the OEM recovery. I have the bootloader unlocked. I have read every forum and website I could find, but to no avail. I've tried different versions of Odin and the TWRP for my model. I'd imagine once I get TWRP flashed I'll be able to successfully install SuperSU. I've read to take the battery out after getting the success message from Odin but the battery isn't removable in my model. Any help would be greatly appreciated.

SuperSU doesn't root Android: it's an application which lets you manage root permissions for apps which require root access.
Android is rooted when SU-cmdlet - by whatever method - got added to Android and is system-wide accessible.
BTW: TWRP isn't needed at all to root Android.

I'm obviously not very good with Android. Do you have any suggestions for me ? From what I've read, it sounded like, among other methods, I needed to flash SuperSU via TWRP in order to get root.
