[Q] Questions about rooting my Galaxy S4

Hello, I have a few questions about rooting my Samsung Galaxy S4.
I want to root to enable some hidden CSC features, edit the hosts file and to install an adblocker.
Not to install an custom ROM.
But I have a few questions.
Do I still get OTA updates after rooting my device?
And what happens after I update, do I lose root, are those CSC features and the hosts file resetted, and is the adblocker uninstalled?
I am currently running the latest version of Samsung.
Information about my device:
Model number: GT-I9505
Android version: 4.3
Baseband version: I9505XXUEMKF
Kernel version: 3.4.0-2082040, [email protected] #1, Wed Nov 27 22:04:32 KST 2013
Build number: JSS15J.I9505XXUEMKF
SE for Android status: Enforcing, SEPF_GT-I9505_4.3_0018
Secure boot status: Type: Samsung
And under status I see "Device status: Official".
Thanks.

I'd like to know this as well. I've got no interest in flashing ROM's or anything like that, just need root to run a few Apps I use. How does this affect updating, and can it be easily rolled back for warranty purposes?
Thanks for any help.

Oh yeah, and do you keep warranty?
We in the Netherlands have a law that the warranty does not get voided if you root it.
Dutch law said:
If the failure of a phone is not the direct result of the rooting or jailbreaking, the warranty remains valid, even if the terms of the seller states that it is not the case.

Root S3 i9300l (XXUANF4) latest kitkat

Until now this firmware I9301IXXUANF4
was unrootable, because towelroot didn't recognize the device, since the kernel has been patched.
I made it to root, by simply downgrading the kernel to the older version XXUANC6 dated 22 march, as @geohot says on his site " .. should support all phones < jun 3 2014
click the lambda, install the apk
run towelroot"
that was just a simple thought I had today. to grab the older firmware and flash the older kernel over the new firmware.
The procedure is simple. update normally to the latest firmware either with OTA or odin, as you wish.
Then go into download mode and flash the kernel dated 22 march from XXUANC6 and reboot.
apply towelroot like normal
if you want the new kernel flash the XXUANF4 kernel. or stay with the older kernel. your choice. Enjoy.

Hopefully this device gets more attention!

I think, there is no benefit to root the mobile.

There weren't any s3neo section back then. A mod should move the topic, please.

Installing stock ROM on SM-G532F

So guys I have flashed TWRP on my Grand Prime Plus through Odin. And now I need to find a stock ROM for my phone.
My question is:
Does the base version (and build version as well) of the ROM you're downloading need to be same to what it used to be before??
This here are some specifications of my phone right now:
Android Version
6.0.1
[Marshmallow]
Baseband Version
G532FXXU1AQB3
Kernel version
3.18.19-10802954

Can someone tell me if the base version and the Build Number needs to be same for downloading a new ROM or not??
And where can I find the best ROM for my phone??
Edit: And does the region of the ROM you're about to download needs to be the same as the region you're living at? Does it make any different?
Also, how do I make a backup for the already installed OS? What do MUST make backup of out of:
Boot
Recovery
EFS
Cache
System
Data
Misc
Modem
System Image
I don't really care about losing data, I just don't want to lose my previous already installed OS while trying to flash a new stock ROM. So what do I make backup of out of the aforementioned?
Thanks.

Where is stock frimware link?

Ready to root: Variant AT&T SM-G935A

Hoping someone might be able to share the latest with me , on what I am sure is a well-covered subject by now. I am familiar with ODIN panel from around 8 years ago, so I assume I will have to download both a working version of ODIN panel, as well as Root, TWRP, Recovery, and ROM, zips, and then use ODIN to flash the phone. It has just been a while And I am looking for a walk through, and links to the stuff I need. If' ChazzMatt is around maybe I can benefit from his mighty knowledge.
Thanks!
P.S. will rooting also kill the insistent SecurityLogAgent message "Unauthorized actions have been detected" message from returning as well?

Galaxy S7 Edge SM-G935A Root...
I would also like to know how to root my Galaxy s7 Edge SM-G935A from AT&T. I've been looking with no success. I was hoping to upgrade firmware to either Lineage OS or Exynos but it's looking like this might not be possible due to the chip AT&T used not being flashable or something?
I was hoping to at least have root access in order to use some apps that require root. Lots of stuff for other G935_ phones with other carriers
Hope there's some replies... Thanks

Can't do custom ROMs since Snapdragon 820 bootloaders are locked down well, and haven't been unlocked to be able to flash a Custom ROM AFAIK.
But I do think you're able to root? Just know it will probably 'Trip your Knox counter'. I think you can use CF Auto-Root to to root it

Possible to downgrade to stock Android PiE with older security patch?

I have an unlocked Samsung Galaxy S8 (G950F) on stock ROM, Android Pie, on security patch June 2019. Is it possible to downgrade it to stock ROM, Android Pie security patch March 2019 using the Odin method? I have already downloaded the appropriate firmware (G950FXXS4DSC2).

No u can't downgrade anymore , your bootloader is on v5 and there is no way currently to downgrade bootloader to older version

Thank you for your response. Theoretically would I be able to downgrade an S8 on the May 2019 update (G950FXXU4DSE4) to the March 2019 update (G950FXXS4DSC2)? If I am correct the digit after FXXU, i.e 4 represents the bootloader version, which is 4 in this case.

Yes u can downgrade to any earlier pie or Oreo frimware as long u didn't install June update

I thought this was possible too. That's half the reason I rooted. A security update messed up my night mode and it's very annoying. Shame. I doubt Samsung will fix it with any future updates.
