Hey guys,
I have a Galaxy s4 I9505 which has been used a bit already. It reached me with already installed Super SU app. Since my phone is already rooted, i wanted to unroot it and found an option on it but it didnt unroot it, rather kept saying please wait and then i gave up. I restarted my phone and now when i try to open it it says there is no SU binary installed.....
Now, how can I unroot this phone so that i can update it.
Thanks!
By update you mean official OTA?
If it's rooted and knox is 0x1 then I don't think you will be able to receive any more official updates.
You might be able to flash them via Odin though.
Installing another superuser app might solve the su binary missing issue
Hi,
With Knox tripped you can still receive system updates, you'll not receive if you have System Status: Custom. And I agree on the latter part, the best solution for you would be reinstall stock firmware using Odin. There are plenty of guides out there, just search for it .
All the best,

Hi,
I rooted my Note 3 the Root De La Vega way. At some point, I lost root (According to Root Checker). However, I realized that my firmware hadn't changed. Then, the latest OTA tried to push to my phone and, without thinking, I downloaded it and tried to install. It failed. I figured that I needed to unroot my phone in order to grab the OTA. I didn't mind losing root. I looked up how to do it and found a thread saying to do it through SuperSU. I tried to open SuperSU and got an error message saying that "There is no SU binary installed, and SuperSU cannot install it..." I then tried to see if I could find the stock firmware and use Odin to unroot that way. I couldn't find the stock firmware for my particular device. Now, I don't know what to do. Please help.
Thanks
Bump?
Bueller?
Use Odin to reinstall a stock firmware. Should wipe everything on the device. Make sure you're on the current base by checking for updates. Then reroot using kingo and install safe strap.

Hi.
I don't know if someone can help me, but I really don't know what to do with this problem.
I bought one G900M (version from Brazil) on the release date and after a few weeks I install a custom rom and the TWRP recovery.
The problem is: I tried to go back to the stock ROM, but I still have the recovery with the CUSTOM "mark".
I tried to re install many times, do a wipe/format from the recovery, with no success.
I always receive the message when I try update the phone by OTA what say "The operating system on your device has been modified in an unauthorized way. Try downloading...
I appreciate any help.

You tripped Knox when you rooted. There's no way to undo this.

But I'm not talking about Knox. I'm talking about the OTA update.
I reinstall the original firmware, stock version. Should work, no? Or Samsung changed the things again?
Im with a similar problem... root my device now OTA dont work... i think maybe someone has a flashable original firmware and you patch the same way you root your device.... Other option is ODIN restore to default :/ wich nobody want that
Its true

If you want to update Just download the stock firmware ( samobile ) and flash with odin
Not true. My knox is still 0x0, I have root, but i have the same message from OTA.
The ART is the problem.
I rooted with towelroot and then wanted to unroot because I was having issues. I was too lazy to just flash a new firmware, so instead I read that if you delete the SU and BUSYBOX files from xbin, it will unroot your device. I unrooted my device and restarted it but I am getting the 'system software not authorized' message. I tried to use odin for hours on end, trying different settings and what not and have no luck (odin needs the phone to be rooted in order to work its magic). Am I S.O.L.? I have the Verizon g900v

Knox doesn't like you messing with system files. By corrupting, rather than removing your root you now have the worst of both worlds. Knox isn't suppressed anymore and complains because it detects some of the changes you made. And your root is no longer functional.
You need to either re-root, either as an end goal or to be in a position to remove root properly. Or alternately you can install a 100% stock firmware so that Knox is placated. Odin 3.x shouldn't object to flashing a full and current Verizon OEM ROM. Note that the latter approach will obliterate your personal settings and data, so a backup would be in order first.
Hello.
I rooted my S5 when I first got it simply to use the volume boost mod. A week ago I decided to unroot so I can OTA update, ready for when major updates to the firmware on the phone are released. Anyway. An updated firmware became available so I tried to OTA update (not really expecting it to work) and got the "Modified firmware such and such" error come up. Obviously, rooting the S5 is different from the S3 due to the addition of Knox to the latest firmware, so I've got a few questions to ask.
Is there any way at the moment to reset Knox?
Does Knox stop you from being able to get OTA updates, even if you use TriangleAway to reset the flash counter?
Also. I checked today in Kies and it let me update my firmware but I didn't proceed with it because I'm worried about it bricking my device. I actually unrooted using SuperSU and checked the status of root afterwards using a Root Checker, which said I'm not rooted. Is it safe then to use Kies to install updates to the firmware instead of using OTA updates or will that brick my device?

- Triangle Away doesn`t work with the S5 and neither us it possible to reset the KNOX flag
- Unroot with the Towelroot or superSU app (wich ever you have installed)
- Flash a stock rom (firmware)
- Data factory reset in recovery after the flash
- Done and now you can update with Kies/OTA.
So I sold my buddy the note 3. It was rooted so I flashed a 4.42 stock firmware back on, knox is already tripped. Apparently there's an update for the device and the msg when he tries to update is software has been modified. I download root checker and it is indeed no rooted. Any ideas?
Because knox has been tripped to 0x1, that phone can never updated via ota or the samsung app. You must now download a updated stock rom, or some other fancy rom. Untill someone can fix knox back to 0x0... This is the only way to upgrade.
Experienced this running stock rom and all (recovery, boot etc). But knox is already 0x1. When i was running XTC (Philippine stock kk rom) i get the message about modified software when checking with ota. But when I use XSG(is the csc correct for Singapore?) And try to do an ota it downloaded the update without a problem.
Heres what you can do use triangle away to reset thr binary recovery to official then flash stock rom and see if you can do an ota without any problems.
