Unroot and reset back to "as new" - Samsung Galaxy S8 Questions and Answers

So I got a Samsung Galaxy S8, and installed TWRP. I by mistake deleted the OS, so I have no OS on the phone now, I want to remove all the root and ****, and make it like a new one without any root. How can I do this?
I have tried multiple stuff using odin, but it looks like it stuck on <ID:0/005> SetupConnection.. all the time. Help please?

Have you tried flashing the same android version as before through Odin using the original cable?
i.e. you had android 7.0 and you're flashing 7.0 now and not trying to upgrade/downgrade

How exactly? All I know is that I had Android 8.0, and bought the phone from Norway.

I'm assuming it's a G950F if you purchased it in Norway so the official firmware from:

and then follow the xda thread above

I will have a look at it when I get home tonight.
I did manage to install GoogleWiz : - but I want to just reset everything, and make it as new. Hope it works with the links you sent.
EDIT: Haha the link you sent with download says Approx. 15 kB/Sec. This will take a day to download

note that you will not be able to restore it 100%. Knox is and will be forever broken on your phone. And for that, all Knox related functions won't work either.

Given you were able to install TWRP I assume your phone can connect to your laptop so idk why it's not working. A quick Google search found people used older versions of Odin to get it working.

I was trying to unlock my phone before this, before I gave up because I had downloaded the wrong version (5.0.1 UK stock instead of 4.2.2 stock, was trying to use the leaked unlock codes) and then I tried flashing TWRP 3.0.2-0 in Odin 3.10-7 which "Re-Partition" was ticked automatically for some reason and I didn't know. Now my phone is soft-bricked and Odin won't cooperate. Help me please!
I will provide more info as necessary!

Can anyone please shed some light on my AT&T S7 root failures?

AT&T
Galaxy S7
Android security patch level: Sept 1, 2016
Baseband version: G930AUCS4API2
Build number: MMB2M.G930AUCS4API2
I attempted to root my phone with the guide you can find by The Unlockr (David Cogen)
I followed the steps exactly but unfortunately it would freeze on AT&T symbol...
So I tried flashing stock firmwares with no luck. So I wiped data/restored factory settings and fortunately my phone runs. However I keep getting a popup saying "Security Notice: Unauthorized actions have been detected." Which I am assuming means I tripped KNOX. =(
Is there a way to remove this trip? Does anyone know a firmware that SHOULD flash properly on my phone?
Here is the error I get when I try to flash the 2 firmwares I have found (G930AUCS2APF2, G930AUCU1APB5)

You may be on a newer bootloader which is why you are receiving the pit file error when flashing lower firmware

The september patch has a new bootloader which means you can't downgrade below API2. And no, you didn't trip knox. That notification pops up regardless when the security log detects that the phone is rooted, So you should be fine. API3 G930U firmware flashes perfectly and works really well, I recommend using it.

It's the firmware of the Unlocked S7 variant, which is Official Samsung firmware. No AT&T bloat or anything.
Performance and battery life have gotten better on this Firmware, and no overheating either.

I really do enjoy the idea of no bloat and better performance/battery life. Theres just some things that I will miss, like at&t advanced text messaging..

Boot Loop and ..

.. I can't access recovery, though I am in download mode.
I have Odin downloaded and running. I can't seem to find my firmware (I haven't done this in so long, might as well be a n00b again) .. I'm looking for the stock firmware for SM-G900V(confirmed) .. Yeah, it's Verizon -_- .. Can't a fat kid get a drum stick?
I'll try looking some more while someone can try to help? Thanks in advance, I really need my phone .. like most people lol doctors appointments and disability stuff. Help a fatty out!

I can see only 2 possible reasons:

Ok, I've tried three different cords, two of which are brand new, and no dice.
I had one successful try on Odin .. Then it started boot looping again .. ugh

So do I.
If you had a successful try, this means that you've flashed a correct firmware at least once.
If the phone still bootloops, it looks like a hardware problem.
I'd be glad to mistake.

Emergency Firmware Recovery and ODIN flash failing

Hi all,
I have a S7 Edge - SM-G935F (UK) - that I think had/has a software/firmware issue. It would boot and be ok if left idle but after about 5 minutes of use it would crash and reboot.
I connected to Smart Switch and it tried to update the software to the latest version but due to the device crashing after a few minutes, this failed. Then I was left with the blue error screen advising a software update has failed and to use the Firmware Recovery mode on Smart Switch. So I tried this and this fails at either 5% or 16% referencing an issue with the device.
Then I tried flashing the stock firmware in ODIN and this fails almost instantly with the following log entries:

Have you taken a look here: https://forum.xda-developers.com/galaxy-s7/how-to/guide-onelatest-stock-fw-csc-root-t3702963 ? It might be of use. If that fails, report back in. Now I think of it, report back anyway.
On top of the problem you got, i got the problem that when i open "smart switch", or Kies, none detects the phone, supposedly i should be able to recover it with the emergency thingy..
Anyway i can get to download mode, but it also fails and im using XEU-G935FXXU2ERGE

Back to stock from Beta One UI on the GS8

Having a difficult time here.... I've got a Galaxy s8 Sprint variant.. I downloaded the Beta one UI firmware, not official just used ODIN. I'd like to go back to stock and update to newest official release, or just go straight to the latest release. I don't care if it's rooted/unlocked or whatever just stock Sprint software. I've tried a couple of stock firmwares but I keep getting errors in Odin. Currently I"m on PDA G950U1UEU5ZSAB CSCG950U1OYM5ZSAB .
Any pointers would be greatly appreciated.

2 things I can see
1. Use Odin version 3.13.1 it supports the new compression format of newer firmware.
2. The software check fail is due to trying to flash older firmware than what is on your phone. You will need to download firmware with a bootloader version 5 ( 5th number from right of firmware(PDA) name ).
OP can you confirm if it worked?
Hey, THanks a ton.. worked! I don't think I woulda figured that out unless I would have happened to tried a rom with the correct bootloader version. Really appreciate it. One more thing.. which should I use normally.. the home_csc or the csc. I've been using the home one since that's what I see a majority of people using but I don't see any explanation.
thanks again!

Glad you got it sorted
Home_CSC - will keep your apps and data.
CSC - clean install same as a factory reset.
