Factory reset and root - Samsung Galaxy S7 Edge Questions and Answers

Might be a silly question, but if I want to start from scratch...if i factory reset will it maintain root or will I have to re root? I rooted via cf root.

[Q] Not booting into CWM

Hi,
I have a Galaxy S4 GT-I9505. I want to make a nandroid backup.
I installed Rom Manager via the Play Store, and I clicked on; Install CWM.
After installing CWM I pressed on the firmware backup button.
My phone rebooted and showed blue letters: Booting Recovery. But I came into the default recovery from Android, not into CWM.
Why can't I access CWM? Rom Manager said it's installed.
Regards,
Michael
Maybe,you need to install a different kernel.

I have stock ROM from Samsung, rooted with Kingo Android ROOT.
Rom Manager said CWM is installed, how to un-install it if it doesn't work?

Using Kingo method you wont be able to flash custom rom/recovery. Root your phone by flashing CF-Auto root via Odin n then you can install CWM. Knox will be triggered.

Thanks for your answer. Do I need to un-root Kingo first, or does Odin overwrite it when I use CF-auto root?
And what will happen with my apps when I un-root kingo? (I have a few apps that require root).

Yes you have to unroot.You can do this from the Superuser app by clicking unroot. Cf auto root works best if the phone is reset to factory settings as this may prevent flashing errors of Odin. For your apps which require root , you have to back up them for future use as reset will wipe them. Hit thnx if helpd.

[Q] Unroot after rooted with Towelroot on SM-G900F?

Hi, I would like to ask you guys if the device can be unroot after it has been rooted with Towelroot?
I heard many people said about using SuperSU to remove the root.
However, I am not sure if the unroot process is safe and be able to give me a full warranty back.
Thank you.

I've unrooted my s5 before and it wasn't hard. Just flash an unroot pda with Odin. Saves all your data. But I think it will trip the Knox counter, so It'll void your warranty. So I'm not 100% sure if you'll be able to keep your warranty

Dude, what advice is this? :crying: Flash an unroot PDA? What do you mean with that?. Just unroot from within the superSU app, flash a stock rom and do a data factory reset. Takes about 5-7 minutes if done correctly.

Flash an unroot tar file. That's what I was told. I did it and it worked fine. No more root. But you can unroot with supersu?? I never knew that

I have tried the method and everything works.
My device is now unrooted.
No KNOX trip after flash stock rom with odin.
The device status is official too.
Thanks!
Still a bit confused
Confused is my normal state...
In Super User the only options I have are for OTA survival and for temp unroot.
To unroot would I only need to select the temp unroot option then go into the S5's settings and do a factory reset (under the backup/restore selections) or would I temp unroot with superuser, then go into Odin (on my pc) and flash a factory rom?
With the Odin option of doing this,if it is necessary, where can I get the factory rom for Version's S5 for this process?
I just unrooted using SuperSu's full unroot option and wiped cache from the stock recovery and boom. Worked for me.

Thanks klacenas, Where/how did you wipe the cache "from the stock recovery"? Also as an aside... did this cause you to lose any apps or files (photos, music, txt files type stuff) when you did the unrooting?
Sorry to be a pain.

By Unrooting only, you will not lost any of your personal data that stored on your phone. However when you do factory reset, your personal data that stored on the phone will be lost.

Try a data factory reset and flash the rom again, that should help.

Hi i want to root Stock 6.0.1 mm and keep stock recovery. So do we have to flash TWRP in order to root stock 6.0.1 mm? Or just flashing the cf-root file via odin alone will give root access? Thanks

CF-root via odin will root your device and you'll keep stock recovery.
I wonder what's the point of keeping stock recovery by the way

Thanks, i tend to use stock samsung rom always, but just like root to remove crap, titanium backup and some apps that require root permissions. Btw what options on odin do we tick when flashing the cf-root file?
Sent from my GT-I9100 using xda premium
Hmm, I guess if you never need to flash anything then keeping the original could be OK.
I'd say trwp is still useful to perform backup (entire rom at a time).
Well normally, you don't need to tick any options (the useful ones are ticked already).
So, only auto reboot and F.Reset time should be ticked.

When i had the S4 a few years ago, i had clockworkmod recovery which was great and i was familiar with, but was not ever a fan of twrp even then, so decided to stay stock with the s5 but thanks for the help mate.

Hi mate, just rooted my s5 via odin and cf-root file. However every time I reboot the phone, i get a "Set warranty bit" message in yellow at the top of the screen, I did do a wipe cache after I rooted. How do i remove that message? thanks
To my knowledge, you can't get rid of this message which was tripped by the rooting process.
But it doesn't make any difference anyway so you might as well leave it!
Then, you can run the root to the Galaxy S5 SM-G900F Android 6.0.1 and Kernel of May 31, 2016 without triggering this blessed knox 0x1?
I still have not figured out if it is feasible, and if you can do as you progress? Towelroot works?

It doesn't. I installed all these automatic upgrades and tried to use towelroot, but it said, that the device isn't supported. :crying: :crying: :crying:
do i need to unlock the boooader before or after
do i need to unlock the boooader before or after?
or not at all?
obviously the first file that i need to flash (twrp) is the custom recovery.
do i unlock the bootloader before this?

basically the same phone just the FD has an extra sim slot
thats all
you can flash anything F related on FD, even the stock firmware
the following steps i do to root my SM-G935F and i don't will miss it.
the first method (TWRP with supersu-zip file and dm-verity disabler install was failed, bootloop)
The second try with CF-Autoroot have rooted it.
Bevore rooting with CF auto-root it's needed that you activate the developer options with oem-unlock and usb-debugging.
Than you make a factory reset about the android-own system recovery (home, vol+ and power)
at next you must change in the download mode without boot the "fresh" system and then flash the CF-Autoroot with odin.
Than you can start the fresh system without any first changes bevore rooting process have starts. The securityLogAgent warns you about unauthorized changes. you can disable this notice. And you must disable samsung knox too because it can behinds supersu. a example s-health will not work with rooted devices. one file edited and it works again.
see here. https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-s-health-devices-knox-t3543306
In the system app menu you can only stop it. Than you go fast to supersu, this app disable it.
