[Q] unroot s5 sm-g900f without wiping data - Galaxy S 5 Q&A, Help & Troubleshooting

I have a samsung galaxy s5 sm-g900f model rooted with cf auto root and it has a software update available so I want to unroot to recieve that ota update without wiping data
All the threads I could find suggest to install a firmware pda file which as I know wipes data
Any solution?
Thanks in advance

Flash the new ROM with ODIN, the only thing you'll lose is root, then you can use CF Auto Root again
That's how I update
samobile dot com will have the new ROM, or check the link in my sig for MEGA links, BOE5 is latest

But isnt there a way to unroot and get OTA updates without wiping and without flashing with odin?

What is your Knox status? Cf auto root trips Knox flag and it should mean you won't be able to receive ota notifications..

I think my knox is 0x1 but I recieved the update notification and when I tried to update it said "the operating system in your mobile has been modified in unauthorized way" does that mean even unrooting wont make me able to get OTA updates?

Yup, with Knox tripped you can no longer update via kies or ota.

Working root that does not trigger Knox!?

I just tested Towelroot on my GT-I9506 running latest NEE 4.3 and it worked like a charm and did not trigger Knox.

Works perfectly!
Please, can you help me?
I've downloaded the towelroot apk and installed it. Then, once the phone was rebooted, I've installed supersu from playstore, but it ask me to update de SU binaries, I select the normal option but it gives me a message about samsung knox and if I want to try to disable it, I select no because I don't know if it will affect to the knox counter.... What are the steps please?
And if I download the suggested SuperSU from the towelroot thread, I can't install it because it's a flashable zip that I can't install because I have stock recovery...

Towelroot installs needed files for root. I didnt install SuperSU at all from play store cause its not latest version.
ChainFire is updating SuperSU soon and when latest version (1.99) is online you can install it from play store.
After Towelroot I just installed Titanium Backup (and pro key) and freezed all crap including knox.
After using towelroot on a KNOX-enabled stock 4.3 device, is is possible to revert back to the 4.2.2 bootloader without burning the e-fuse?
Ok, tried to delete system apps, including the knox ones, with root explorer and was successfull!
And about the downgrade, it will change the knox status for sure, because knox is in the bootloader too, not only the apps and libraries, and here, root doesn't made any chance...

The KNOX e-fuse should be burned only by the bootloader in ODIN mode when it flashes an unsigned file to the device. Getting local root on the device and writing a new bootloader directly to the flash should not be able to affect the e-fuse?

It is slightly wrong. You shoud burned KNOX when you flash different version of kernel, recovery, bootloader.
You can flash system, modem, NON-HLOS and maybe others. I've tested only system and NON-HLOS.
Now I have my GT-I9506 Singapore version with KNOX warranty void 0x0 in this configuration:
System and NON-HLOS from Finladian version: I9506XXUBNE1
The others from original Sigapore version: I9506XXUBND2
towelroot.com installed and working!
Thanks to towelroot

Yes, but you are talking about flashing this via download/odin mode, right?
My point is that with root, you should be able to modify the flash directly, overwriting the bootloader.
Would it be possible to receive original updates OTA with this root?

As we have root I would think (so don't quote me on this) that OTA is blocked. But as I see it it does not really matter as the next update for this devise is probably going to be 4.4.2 and flashing that probably also means loosing root.
Now that was a lot of probably but as I see it..
You need "Official" status under Phone Info to receive OTA updates. ROOT will be overwritten by the updates.
After root it's very common to have "Custom" status, but you can cheat it with Traingle away app (not tested by me) or sometimes you can be "Official"after Wipe ( it depends what changes has been done to the system)

I would think getting the OS" 4.4.2 is only part of the package (BTW 4.2.2 vrzn w/gs4 rooted with ease) but you also get other surprises...
Not exactly like a box if lucky charms either.
Samsung or vrzn either one are not fond of rooting.
Triangle away didn't help me unless i did something wrong.. I still have the unlock icon when booting and phone info says "custom" but knox is 0x0

Don't know why he doesn't label his site or the filename better but it should be the latest version when you download from his site.
When you open the app to install it, it should say the version at the top.

[Q] Firmware upgrade after towelroot done

Knox shows 0x0 In future when I have to update firmware through official OTA update I won't be able to do that since it writes that system is modified. Any thoughts?
Mine shows knox 0x1.
Now, when i try to check software update, it gives me error report.
But your's one should be fine.

just use unroot option in superSU

[Q] G900T software update = Towelroot gone?

I unrooted my G900T (previously rooted via Towelroot V2) using SuperUser so that I could update my firmware via Kies (OTA kept failing every time regardless of being unrooted). Now I'm unsupported by Towelroot... T_T
Has anyone else become unable to root theirs after the update?
Previous firmware: G900TUVU1ANCH
Present firmware: G900TUVU1BNF6

You can root using cf-root method be chainfire even if you are on the latest firmware
but be carefull it will trip knox and void your warrenty
if you dont want this you have to wait an update for towlroot to be able to root the latest firmware
I dont think towelroot will be updated seeing as geo works at google now...

Ah yeah, I was using towelroot precisely because I didn't want to void knox. Blah! I've only had it rooted for less than 2 months, so I haven't really done much to have it bother me anyway.

Or you could do a forum search and stumble across better options.
No need to wait for a towel root update.
The latest update may block the Towel root exploit.. but you can still use Odin to install a pre-update version of your stock firmware and [drum roll], towel root will work again. And no Knox increment.
Samsung may eventually add another qfuse to block this method, but for now it works well. You need to revert to a pre June 3rd build of your stock 4.4.2 S5 software to do this.

say yes to removal of knox and also try apps like ota root keeper
sometimes after enabling survuval mode in super su results in ota failure cos sometimes it happens that you remove some system apps after rooting { which i am sure you also have done } and the update consist of files for those uninstalled apps then you get such error
I have installed ota root keeper now.
in status it shows root acces.
In superSU i have unticked ota survival.
Tryed again to install update from ota but still have error.??

Why don`t you just flash the new updated rom with Mobile Odin Pro and enable Everroot and the other 2 options and keep root and forget about these OTA`s. Roms are available at Sammobile.com/firmwares. Just wipe or rename the OTA policy and notifications.

I have Mobile Odin.. But it says that my device is not compatible or something...
If i just make the update from KIES.. Can I then get rooted again by CF-Root ? And if I do CF-Root.. Will I still be able to get updates from OTA or KIES =?

What S5 model do you have mate that MOP is not compatible? If i we`re you i`d forget about OTA`s anyway and just flash the updated rom with (Mobile) Odin. OTA`s suck imo.
To disable OTA`s and notification go to /system/app/FWUpgrade.apk (+odex file) and delete it and in /system/priv-app/FotaClient.apk(+ odex file) and delete it.
Yes, you can use CF Auto Root to root again.

I uninstalled Kies myself, if you accept the OTA it will probably not be installed because you are rooted. I would download the new rom from Sammobile and flash it wirh Odin. Have you tried clearing the data of Mobile Odin Pro because the G900F IS compatible with MOP.

You can un-root in the settings of the SuperSu app,it will remove SuperSu and all its files from your system.
However it will not reset your tripped Knox.
If you rooted through TWRP,un-rooting will not remove TWRP , this can only be done by flashing a stock ROM through Odin.

So if your rooted with cfroot and get an update from samsung, just use supersu to unroot, install the update, and root again? The update should install with even with knox tripped right?
Isn't there a way of flashing just the recovery rather than a whole rom? It seems that's what the updates are looking for when they try to install themselves.

Nonsense. KNOX won't affect OTAs at all; if you have a stock unrooted rom installed you'll get OTAs.
You can flash a newer ROM over an older rom in ODIN and retain your settings and data. There's a chance your ROM won't work properly though and you might get some System UI crashes in which case you will need to nuke your data.
how can i find a stock rom for my phonemy baseband version is G930FXXU1APB6 and its a g930fd the only ones ive found are saudi arabia and pakistan. can anyone give me a hand
If you're just worried about getting ota updates, just use flashfire. It will apply the update without losing root, apps or settings.
