Hello, recently I've been rooting my SM-T555 like a year ago and something went down, and I think I didn't root it properly. But everything on it works perfectly fine, except one thing. When I try to update it from Android settings, it says something along the lines of "This device has been modified in unauthorized way. Try downloading devices using blablabla..". So my question is, would there be a way to completely unroot my table so I can update it this official way?

UPDATE...
nvm, delete this thread i guess. redid entire process second time, maybe got impatient first time. now, installing cf/SU and ti backup seem to work as they should, ti backup asking for root access and happily doing its thing now, which would have to mean the phone is rooted, yeah? heh.. whats what i get for brainlessly taking the OTA update recently without thinking before acting.
---------------------------------------------------------------------------------
stock (i guess) galaxy S5, ATT, ANG3 update recently.
total brainfart. wasnt thinking about root which id kinda forgot about and wasnt super concerned about, even though its always been on the to do list.
im using this method...
http://forum.xda-developers.com/att-galaxy-s5/general/g900and3tong3keeprootota-zip-t2862299
and the process of flashing seems to work fine BUT after going back to the older firmware, it still shows NG3.
why is that? i cant even tell if its actually rooting the phone, even though towelroot (when used like the guide says) doesnt return an error or reboot the phone.
phone isnt bricked, still works fine.. calls email wifi etc. its just not DOING anything. NG3 preventing going backwards, perhaps?
Hey everyone!
I've got an interesting predicament here. A little back story: a while back I installed TowelRoot, and then Xposed Framework. Everything was kosher until I got an OTA update (I believe the NG3 update) and it killed the root. No problem, I'm fine without root. But now that Lollipop has come out, I want to update but can't. My buddy applied the same root, but did not do Xposed. The difference between our phones after that OTA update: mine says "Custom" with an unlocked padlock at the Samsung boot screen; his does not.
I read in another thread that someone took their phone to Best Buy and the guys at the Samsung booth were able to fix the problem because they can pull updates and apply them via USB. So we went there yesterday and they had no problem getting Lollipop on my buddy's S5 Active. Mine, however, would not take the update. The Samsung S.M.A.R.T. tool they use on the PC was saying that "my device is running an unauthorized operating system", even though I have never flashed a custom ROM.
When I go into download mode, the Knox flag does not appear to be tripped. I've also performed a clean factory reset with a data wipe and that still didn't allow me to update. Whenever I try to update, it downloads the entire 4.4.4 update (which needs to be done first, before the 5.0 update) and it starts to install, failing at 25%, without hesitation, every single time.
I've attached a couple of screenshots that I hope will help. Any ideas will be greatly appreciated.

Have you resolved this issue, if so, would you mind sharing how you did it. I've been combing the net for a few days trying to discover what is going on and your issue appears to be exactly what I am experiencing. I've read about flashing back to my stock firmware using Odin but I cannot get into download mode, when I try and get there, the phone only says "recovery reboot" in blue small font on the top of the screen and reboots.
Thanks
Ladies and gents, I apologize for abandoning this thread. I forgot exactly how I got to get the phone to update, but if I recall correctly, it had to do with me putting the phone in download mode, downloading the original firmware and using ODIN to flash it. Afterward, the "unlocked" padlock symbol disappeared and the phone was able to get the OTA update from AT&T.
I have since moved from an LG G4 to a V20 and that is what I am currently playing with. I also have a Samsung Galaxy S6 Edge (which T-Mobile replaced my G4 with when the touch screen stopped responding). I was quite stoked to find out that there is a way to root it and (seemingly) unlock the bootloader, so I'll be toying with that this weekend to see what I can do. I'd love nothing more than to just wipe that Samsung-ified Android and install a vanilla Android or CM.
Good luck to anyone who is still trying to fix this issue. Again, my apologies. I'll dig through my archives and see if I can piece together what I did to get it going again. I still have the S5 Active. Best phone by far. It's a great backup phone for when the new stuff goes kaput.
Hey Guys, I'm brand new to these forums, and to this whole community so bare with me.
Basically I bought my T-Mobile Samsung Galaxy S5 phone around the time it came out, and I also had installed root on it via towelroot when Towel Root was first released. I did not update the phone at all for a long period of time and everything was working fine, until one day I was browsing under settings and accidentally tapped the "Software Update" button, then T-mobile auto-pushed an update onto my phone.
This update has caused the root on my phone to not work at all (Deemed useless) So I clicked SU and only a black screen popped up when I tried to open the app, so I uninstalled it, reinstalled it then got a message saying "There is no SU binary installed, and SuperSU Cannot install it. If you just upgraded to Android 4.3 you need to manually re-root your device" So I tried to re-root via towelroot method again. It seems the T-mobile update made my phone "Unsupported/Uncompatible" with TowelRoot's obsolete techniques, so now I'm in dire need of help.
My phone tried to push another t-mobile update (This time to upgrade to Lollipop) but it failed after attempting to install it after a reboot. So not only will my phone not update to Lollipop, but I'm not even rooted anymore and am unsure on how to get back rooted, or what to do next since I used rooting as a primary source to store apps on my SD Card. Kind of like i'm stuck in one spot? (Can't update your phone/can't root it the old method)
I'm brand new guys, Please can you break down to me what I should do, in order to obtain root again, and possibly be able to upgrade to Lollipop As well as prevent further pushed T-mobile updates? Here's some info if you need it
S5 Model Number: SM-G900T
Android Version:4.4.2
Kernel Version:3.4.0-262.. etc. (Tell me if you need the full kernel details)
Any help would be greatly appreciated! Thank YOU!
Flash this with ODIN
http://download.chainfire.eu/407/CF-Root1/CF-Auto-Root-kltetmo-kltetmo-smg900t.zip
(Will trip KNOX and void warranty)
Or flash a pre-June 2014 KK Kernel, root with Towelroot again, then flash back your current Kernel
Is this the only solution? And also is it the right one? o.o
Can anyone else please give me some feedback on the situation? I want to make sure I do this right, please just a little helps.

Hey I did exactly what you said and it worked I got root back, but I was wondering how to flash back to my current kernel and keep Root?
Hi guys, i recently tried using odin to flash ROM, however it started rooting it and it hasnt finshed it and failed, after that when i use root checker it says root access is not properly installed on this device. And no longer see BIXBY VOICE working (security patch is april) So my question is does my phone still count as never rooted, will i be able to update my phone software via wifi like i did before, considering i dont want my phone rooted, and can i fix the status to not rooted? Thanks in advance
I am very new to all of this, so I am sorry if I'm ignorant about it, and honestly I don´t even have any interest in rooting my device (SM-G950FD), but when I check for new updates, it says the cellphone is already updated to the latest version (Is not, it is currently on 8.0).
I recently bought this phone to a friend and he claims to have never rooted the device, nevertheless, some things point to it being rooted. When I try to use the Samsung Pass App, a text pops up and says "You can't use the app because you rooted your cellphone." Besides this, I can't update the phone or sync my google photos pictures. I installed a root checker app, and it says "Sorry! Root acces is not properly installed on this device."
I was planning on followint the steps of a youtube video from HighOnAndroid called "How to Unroot Galaxy S8 or S8 Plus w/ Stock Firmware!" But I am afraid I can brick my phone if it's not already rooted. So I don´t know if I should just follow those steps, or first root my device (Even if I don´t know if it´s rooted yet) and then fo what the video says.
Thanks!

1. No you don't need to root to upgrade your phone.
2. You can check in download mode to see if you phone has been modified / rooted. Should have a line saying something like Warranty Void. 0 means phone not modify, 1 means phone is modified.
https://android.gadgethacks.com/how...-s8-into-recovery-mode-download-mode-0177223/
3. You can download firmware from sammobil.com or updato.com ( there are other site as well ). But download speed are slow. You also use PC app like samfirm or frija to download latest firmware.
