[HELP] Samsung SM-G950F system & Os recovery ? - Samsung Galaxy S8 Questions and Answers

Hello,
Here is my problem.
2 days ago, I wanted to root my phone to get rid of any Google stuff (at this point I didn't know the existence of ADB commands :crying: ).
I followed a step by step youtube tutorial (youtube.com/watch?v=ZD-5twDm6XI), which works with TWRP, magisk and Odin (factory reset is needed).
Once everything is finished, my phone is finally rooted, and I grant superuser rights to Titanium app to uninstall google, and only SOME apps uninstalled totally (maps, chrome, facebook) BUT google play services won't uninstall. So, I try with System App Removal to uninstall google play stuff, and the same happens.
I reboot my phone, and it seems that everything disappeared... Not so sure... Indeed, the play store reinstall all applications as soon as I connect to the WiFi! and I have a persistent message "google play services stopped" that prevents me from browsing for example.
At this point, I use ADB commands, to remove anything which contains "com.blahblah.google.blahblah" and the play store (com.android.vending) with -k command. And it worked totally fine !!!!! I disconnect my phone, ready to backup my data. Idkw, i wanted to uninstall system app removal. IMPOSSIBLE from the phone, which says : "samsung One UI stopped" (I was in safe boot mode). My phone doesn't answer, so I reboot it.
Once it has booted, the TWRP menu screen appears. Ok, isn't that weird ? I swipe to allow changes, then I go to system to boot "normally" my phone.
A warning says : NO OS INSTALLED !!!! I don't understand, I panic, but finally boots my phone. Black charging screen. Forever.
I started first to flash an "official" Samsung ROM from Sammobile. TWRP indicates it is an invalid .zip, adb too. Odin doesn't manage to boot from the ROM too. I take a deep breathe and cry. Then I download the /e/ ROM which works fine !! but it has become impossible to backup my data from my samsung account....
So, I came to ask you a few things. WHY did it happen ? How can I be sure that there is no trace of TWRP anymore ? However, my phone storage is 64 GB and there is only 53,5 Gb free of internal storage !? Do you think the original firmware could be "hidden" in my files (e ROM is about 800Mos compressed) ?
It is stupid, but after my mistakes, I miss google...
I will do my best to reply asap.
Thank you for your help !

Google writes and distributes android.
There are many things in android that you cannot remove and still have a viable system.
imho you will have to flash a rom but we need your phones information (found in settings/system/about phone) model, version baseband, etc. etc
Others more knowledgeable can step in and help.

Thank you for your reply ! I've read your article about FRP but I'm afraid it's not my problem...
Here are some of my phone specifications :
model : SM-G950F
version baseband : G950FXXS8DTC1
OS : /e/ version 0.9-p-dev-dreamlte (LineageOS API : Ilama 9)
Android 9
I've been digging the web for ROMs but each time I feel unsecure about it (virus, etc...) so I hope maybe you have something trustworthy

I've been browsing through my root files and folders ( / ) ...
So :
/system is occupied with 2.33 GB
/vendor with 577 MB
/mnt with 9.01 GB
/proc with ... 236.9GB but every under-folder is empty... (explanations welcome !)
/storage is empty
If anyone could check on his device (S8 Exynos with android 9.0 Pie and One UI) if the files' sizes approximately matched, it would be great !

The one I just received is G950FXXS8DTC6 / G950FOXM8DTC1 / G950FXXS8DTC1 (after it took the Apr 1 update) so probably identical - a Yateley GU46 6GG UK phone. I am running it on ATT Prepaid(US) , which gave me the Apr 1 update. I don't know its history but it hasn't been modified - knox=0.
What you would need to do is get that zip and flash it with odin, but having no experience flashing the S8 myself, or any idea where to get that zip, I can be of no help to you. (I just came off a moto x4 which I ruined by flashing a couple custom rom's to try to help others on that forum - the blessings of Pie on that device!)(plus, taking the Apr 1 update on that phone requires a factory reset/wipe.) I needed a dependable phone here and in Europe on vacation.
Keep posting and ask someone to help you re-flash it.
EDIT: I wonder what a settings/general management/factory reset would do. But don't do one until someone here much more experienced with the S8 suggests it.
EDIT: WARNING WARNING WARNING -> Before flashing, ACTIVATE PIN in "Secure startup" (You'll be asked for it AFTER flashing!)
lockscreen and security / secure startup / require pin
I also see a note to delete your google account before doing this. Don't know if necessary.
EDIT: I believe I have found the rom - see pic This is from the SamFirm exe. 0.3.7 I put VOD for the region.
Remember: don't do anything with this until someone experienced in S8 tells you to!

Hi KrisM22,
I've already flashed with Odin, and I have talked about this on different forums, seen tutos on websites,... I hope this time it will work
I have the ROM required, selected activate pin, followed step by step the recommendations, and if I figured it out I will keep you up to date !

Excellent! What ROM did you flash it with?

I flashed a ROM from https://www.imei.info/download-firmware/samsung/samsung-g950f-galaxy-s8/SM-G950F/ , then I just followed the steps and flashed with Odin. TWRP has disappeared (the classic recovery menu came back). I think I have found my issue with the "no OS installed" bug : it could be because I deleted the essential API com.google.android.packageinstaller, what may have prevented the phone from booting and launching the OS and its apps .
I should have read this excellent post before...
*I ran antivirus analysis with virustotal and Bitdefender, which both declared the extracted files were safe : I didn't notice anything different by my phone compared to the original OS too, so...

How to fix your Chinese Samsung Galaxy I9220, (add google market and stuff)

Hi,
I live in Shanghai, China. Everyone who lives here knows that any phone you purchase here , even good brands (such as Samsung etc..) will not any have google applications installed. It's almost impossible to get these phones fixed without changing their roms, which is inconveneint and dangerous. From my personal experience once you change the rom of your chinese phone to a foreign one, you will never get the optimum performance. I first purchased a Samsung Galaxy S5660 in China. It worked perfectly expect for the fact that I couldn't use any google app. After being unable to add these applications, I finally flashed some rom from Europe. Then the market etc , all google apps worked fine but the performance was bad. Battery life was really poor. Also I changed several roms after that , none of which gave me the same performance which I had with the original chinese rom.
Now I have got a new Galaxy Note (not N7000), in China it's called I9220. I ran in to the exact same problem. No market, no google , absolutely nothing!! After a lot of research I was able to fix it this morning. If you have got the same problem then follow the steps. Here is how you do it!..
(But I must warn you that I am not responsible for any damage to your phone. Please do it at your own risk).
First use this video guide below :
URL DELETED
//Since this is my first post, I am not allowed to post any links. Please go to the website rootgalaxynote.com and search for the article "how to root ics on galaxy note gt n7000 no computer required".
All credit for this vdeo goes to the guys at rootgalaxynote.
In the above guide follow both recommendations. I mean root your device and then also change your kernel to FrancoICS. Both worked on my I9220 without any problems. My phone started and it was already rooted. Also I got the Clockworkrecovery as the default recovery.
Once you have finished this task, the final task is adding all the google applications. This is quite easy and I did it myself.
1. Go to the website goo.im/gapps and download the latest ICS gapps zip file, currently it is gapps-ics-20120429-signed.zip.
2. Save it to your external SD card.
3. Reboot into Clockwork recovery mode (you should know how to do this if you have already succesfully rooted your device using the above method)
4. Choose "install zip file from external sd"
5. Find the Gapps file and install it.
6. Done, and restart your phone.
You now have your Original Stock Chinese rom, but it's rooted and you have installed all google applications. Just make a google account and you can use the android market.
Even with the google market working , you cannot access many application since you are in China. If you want to be able to download all applications available in the USA for example, then you must also install marketEnabler.
Here's the link :

//Just google search market enabler, you will find it very easily.
1. After you install it, run it and choose T-Mobile (USA) and then click Fake this provider now.
Now if you use Google Market, you should be able to install or download almost any app (such as youtube, facebook, skype etc...)
I hope this is helpful to all the foreigners in China who are tortured by Chinese android phones that only come with Chinese bloatware and doesn't allow you to install any English app or access google stuff..
Good Luck!
Note : When I got my new phone today, it already had ICS so this whoe process worked for me. If your chinese I9220 isn't ICS, it's gingerbread, then don't attempt it, because it might not work.
Thanks a lot. It works on my Samsung S7562 which bought from China.
i have the same phone Galaxy Note ( I9220) bought it in china, i am faced with the same problems with Google accounts and no play store i was following ur instructions on first rooting my phone using the galaxy note N7000 method without a computer but am stuck at Press Up Volume + Power + Home android system recovery how do you enter that mode?...plz help me as i bet ur phone is the same as mine

first switch off your phone then press the three button combination i.e. power +home +volume up and then when you see it getting started(when your phone model no. is shown up) then release the power button and continue pressing the other two buttons i.e. home +volume up

lol you are funny, Franko kernel was developed at xda, he quit developing, not sure why could have been ungrateful community, Its always had lots of bugs, but if it works for you it works. I wouldnt be surprised the rest originated from xda as well.
You better be careful with cwm. zip its been known to superbrick devices. Safest way to root would be the drPhills superuser and busybox zip, flashable as a upgrade zipbfrom stock recovery.

Samsung GT-S7568 China Model
Hi There.
I am new to this site but feel the solution posted would have fixed my problem had I found it before I tried messing around with ROM’s.
I have just returned from Shanghai where I purchased a Samsung Galaxy Trend GT-S7568. This model appears to only be available in china from my research. It is an original Samsung product not one of the many fakes out there.
In my attempts to get it to work with an English ROM, being the idiot that I am. I never created a backup of the system. I appear to have soft bricked the phone and I am unable to find a tool that can fix it. I am also unable to find an original stock ROM to attempt to get it back to the original Chinese firmware.
I have tried OneClick and I have also tried a firmware for the GT-S7562 (possibly what caused my current issue). I have found the Samsung official open source download page and have downloaded the correct files from there but have no idea how to prepare them to be transferred to the device as the “read me” file is not much help that came with the download.
Currently the Phone will boot into Download Mode but no matter what ROM I try The Oden Tool keeps failing at the complete Write operation.
I am hoping that I have posted this in the correct forum. If I not I am sorry but it is the closest I could find to my situation.
Any help or direction anyone may have would be greatly appreciated.
Thank You!

Thanks,my phone is GT-I9220, And this thread truly helps in rooting installing google apps.
What I want to add is to prepare an external sdcard before watching the video,
ar....
i have the i9220.
All i have to do is odin the stock rom from Hong Kong. (available @ SamMobile)
It is fast and stable, no problem whatsoever, and it has good battery life too. (that is only if you do not activate everything and keep you account in sync as little as possible, i only have google and facebook under sync.)

Hy, i'd like to root my S7568 as you did. Did you use the same files for Galaxy note as it is showed in the video?
Thanks!
Can't root my chinese mobile! Please give me some hope!
Hy everybody!
As I have bought a chinese samsung mobile, I can't use google play. So I'm trying to root it. I went through many software as Root_with_Restore_by_Bin4ry_v30 , SRSRoot for Android , SuperOneClickv2.3.3-ShortFuse and more. I also tried to do it as it is said in thoses previous post but there is nothing to do...
I think it's because my mobile:
Samsung GT-S7568
Ice cream sandwich 4.0.4
Is only available in China and all thoses software may not support my device.
So here comes my question. Do I have still any chance to take?
Thanks a lot!
Denffy
PS: the mobile is not a fake!

Hey! I got the same phone and the troubles coming with... Did you find a solution since then? I tried many differents softwares to root it but nothing does the job...

i have same issue here, did you find any solutions ?
AFAIK when you factory reset your phone etc. if rooted you must remember to go back into Developer Options and re enable OEM Unlocking. This depends on the method you used to root, if you flashed dm-verity then you "May not" have this issue but cannot say for sure.
If it is already too late for you then I think you need to flash stock via Odin, plenty of threads out there on where to find the firmware (SamMobile) and how to do it. Even a quick google of the error gave me plenty of results...
One thing I have read is that you may have to keep trying to get your phone into download mode as the timing is much stricter with this error message.
I've the same problem with my g935x blocked on FRP when ii treid to root if any one can help .plz

@djluisbento This method seems to be interesting. But would you please clarify more about it. How to install the apk file on official recovery? Or it's enough to have the pendrive connected? And if yes, when this step should take place, after flashing the official ROM or when?
I'm stuck in a boot loop into recovery mode with dm-verity error, and unfortunately I have the FRP locked, so I can't install TWRP to flash the no-dm-verity.zip file to skip it.
Appreciate your suggestions.
I have the same issure. stock firmware wont install either. im just stuck on the FRP screen, cant even get into recovery
Same issue here, please help
Everything was fine with rooting and installing TWRP. after that did a restart/ attempt to goto twrp recovery, from then the s7 edge is stuck at "Custom Binary Blocked By FRP" and doesnt boot. please help!!
Have you do a Wipe then Format Data.
Then flash the no-verity-opt-encrypt zip in TWRP
Only if you want internal storage or data to work in TWRP:
Go to [Wipe] -> [Format Data] (not advanced wipe) -> type "yes".
WARNING: This will wipe your internal storage, disable encryption, and factory reset your phone!
Go to [Reboot] -> [Recovery].
If you want to be rooted with SuperSU:
Download the latest SuperSU by Chainfire.
Without exiting TWRP, transfer the SuperSU zip to your device over MTP* and flash it using [Install] in TWRP.
If you only want a bootable system partition or writable data in TWRP:
Download the latest dm-verity and force encryption disabler zip.
Without exiting TWRP, transfer the no-verity-opt-encrypt zip to your device over MTP* and flash it using [Install] in TWRP.

Had that problem with a brand new phone, just wanted to get into download mode to see if the phone was tampered with and boom, flash screen with the red warning, flashed stock KSA (phone original CSC) , worked and phone was formatted, another surprise was faced, google did not accept my gmail account, had to shut down phone for 72 hours as read in my google search for people encountering same issue, once the 72 hours passed I was able to sign in and using my phone again.

Yes, flashed both Zips in recovery. I used my regular google account during the initial set up. If i wait for 72 hours, will the phone just boot back online just fine? Still, how do i make sure it wont goto the FRP lock again while trying to reboot or reboot to TWRP?
Solved,
Flashed with stock firmware, logged in with same google account, rooted with TWRP, installed Zubi's sound mod. Made sure to keep the 'OEM Unlock' stay turned on.

Helo
But U did this after 72 hours?
There are several methods depending on firmware version installed on your phone. Basically you have to enter in your phone, launch chrome, install an app which gives you the possibility to log into your google account from chrome and not set-up program.
I used successfully the Bluetooth method. Search for with google. You need a bluetooth headset and follow the steps described on youtube.
BTW. My phone was brand new and I flashed different official samsung firmware ( csc). I had to change google password in between and that resulted in FRP lock....
The wait time is 24 hours as is stated in google docs from site

Hello I have a related problem, opened a new thread, but my thread was closed, because my problem is related to this one, but more complicated. I have the same problem with FRP lock as described here, I can turn on the download mode but it wont be recognized by my computer. I tried different usb cables, drivers, even computers, it wont help. I cant flash it with odin, smartswitch, kies, no matter what I try. If I go to recovery mode it says `dm-verity verification failed...`and if I choose `apply update from ADB or SD card` it says `update from external storage disabled`. I dont know what to do anymore Its a new phone
FRP Block - no Dev Tools enabled
Hey guys,
you're my last resort, I've tried everything I happened to come across, to no avail.
First off, I did something incredibly stupid, don't even ask me why, as I have no idea what the heck drove me to do this in the first place.
Anyways, I was using the stock ROM on my S7 Edge, not tweaked or tinkered with besides the usual CF-Auto_Root. It never caused any trouble whatsoever. But for no reason at all this morning I decided to disable USB debuggin and OEM unlock. A short while later I rebooted my phone, which ended up in "Custom binary blocked by FRP Lock".
I gave a factory reset a try, but that obviously didn't change a thing. So I went to sammobile.com and downloaded the latest official stock ROM for my device and tried flashing it with Odin. Unfortnately Odin always fails with "Complete(Write) operation failed.", which I assume is because I messed with the settings in dev mode.
Next stop: ADB. I've never used that thing before, but I thought I should possibly be able to get it done following a simple guide. Unfortunately ADB won't even list my device when typing "adb devices". It's just an empty list.
So please guys, give me some tipps on how I can bring my phone back to life.

(Soft-)Bricked S7 Edge/G935F with FRP lock & DRK error, but no root/OEM unlock/ADB

(Soft-)Bricked S7 Edge/G935F with FRP lock & DRK error, but no root/OEM unlock/ADB
Hello guys,
I bought a, what I thought to be, soft bricked S7 Edge (G935F) from the bay. It was listed as having sw issues, so I thought I could easily fix the issue myself. Stupid me, this one really isn't easy to fix. I've tried a lot of different hints that I found meandering around the web, but none of them have proofed working so far. I would appreciate some help because I don't seem to be making any progress.
When I got the phone, it would boot directly into Android Recovery with a dm-verity error on the bottom.
Below is what I have tried already:
1 . First I did the obvious, factory reset and wipe partition. No change.
2. Downloaded the latest firmware with updato (SM-G935F Region DBT) and flashed with Odin. It then booted into a screen with a hazard sign and a DRK error (Device does not have DRK, please install DRK first. press any button). Then returned to Android Recovery with variations of the DRK and dm-verity error messages
3. I flashed the same firmware again. This time the phone booted up to a Samsung error that said to use SmartSwitch's Emergency recovery. I tried but it asks for a recovery code and I don't have one.
4. I used an older version of SmartSwitch which gave me the initialization option where you need to input the device model and SN - SmartSwitch decided not to cooperate and noted that the S7 edge does not support initialization
5. I tried to flash CF-autoroot but it gave an error in Odin and failed because it is "Blocked by FRP Lock". I can't boot normally into android. Any workaround?
6. I used a dm-verity workaround file (G935FXXU1DQC4_FIX_DRK_dm-verity.tar) to actually get the phone booted up- but then it asks for the account information to do away with the FRP lock. And the former owner does not want to give me his login information. In addition, none of the workarounds (bluetooth, modem terminal prompts, etc.) did work.
7. Flashed oldest Android version I could find for the G935F - 5.1.1 - this gave me a prompt right after reboot that looks like the password request for encrypting memory. default_password and variations did not work. I am still stuck with...
No Support SINGLE-SKU
Supported API: 3
dm-verity error...
failed code : 0x02
...in the recovery
8. I flashed the combination file and was able to boot into Factory Binary and used the IMEI recovery option which is supposed to fix also the DRK issue. No luck.
So, this is where I am right now. If anyone out there still has sparks of hope, I would be delighted to hear about them.
Thanks much in advance!
Conversion software and ADB Shell
Small update - I booted into factory mode again using the conversion firmware. This way, I could connect to the device via ADB and use ADB shell. There is a guide (here: https://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516) which guides through IMEI recovery using the conversion software and factory mode - that is supposed to also help with DRK issues. Did not work for me.
Another great guide (here: https://forum.xda-developers.com/no...fix-drk-dm-verity-factory-csc-serial-t3422965) used ADB shell to push and repair the DRK with some additional files. Since the device is not rooted, I did not get very far, either.
So, no progress whatsoever.
In summary, I can get the device booted up into factory mode using the conversion firmware, or, by using the dm-verity tweaked firmware, I can end up in the Google Account locked part of the initial start-up settings.
Any ideas?
Have you looked at the process to completely re-do a phone stuck in the Google auth log-in? At least that is how I understand where you are stuck. I have a phone arriving soon that I will need to re-flash to get out of that, via Odin.

Hi JeffDC,
Thanks a lot for the reply. How would this process look like? I have flashed the phone with all sorts of variations of Android L, M and N - plus the combination fw and the one with the dm-verity/DRK workaround which at least got the phone booted up. But then I am stuck at the google auth request.
I cannot flash anything custom since the FRP lock is on.
Hence, if there is any other way to re-do the phone as you are saying, I would live to hear about it.

Hi JeffDC,
Thanks a lot for the links.
Link #1: I can flash the file #1 and get the device visible for ADB by using the combination FW before starting the steps. Unfortunately, step #2 does not work due to lack of permissions. I guess because of missing root.
Links #2 and #3: These are the guides I was already referencing in my post #2 - they both do not work due to, I guess, missing root.
Smart Switch initialization
Update: I got smart switch to do the update and initialization for the device. Workaround was to use a different real serial number than the one of the actual device (I can only assume that it has got to do with country presets).
Cool stuff, all went smooth - but, still the same result. The device ends up in recovery showing the dm-verity error (failed code : 0x02) with FRP lock on and no root.

Interesting read, particularly ignoring the trojan squabbling.
Uses script and setup files to get around FRP.
I suggest you to re-try flashing with Odin the Stock Marshmallow Firmware. Then Boot Into Stock Recovery do a Full Wipe.

Hi JEffDC, thanks for the follow-up hints. Very interesting read and approach. As commented in the other thread, I think the package download link in the opening post is dead. I am also curious to see 2 more complexities in action:
1. Will this work on a G935F variant (Exynos vs Snapdragon)?
2. The only way for me to get to the Google Account prompt is by using the modded dm-verity version mentioned in my first post - but I am not sure I can get ADB access enabled simultaneously
Good luck.

Hey sathiere,
Came across this. It apparently removes the FRP before the system can start it up! Let me know what you think. I'm going to try it on a locked Edge next week or two. Seems to go right after the FRP protection file.

Yes, I am hoping for a response to my post there, near the end, clarifying. I think I get the method, and it's really pretty straight forward, really.
sathiere, I think basically what it does is provide two connections to the phone at the same time, one via Odin, and the other via direct ADB.
Step one is to flash a Universal boot loader, which is unlocked or can be unlocked via ADB. Now with the locked boot loader out of the way, on to getting rid of FRP.
Step two is run the. bat file which deletes the Persistence file, which is the Google encrypted setup file/FRP file. BOOM, FRP gone.
Then either stay on the Universal bootloader, or go back and flash the OEM.
Brilliant!
I have the same problem with a sm930f binary 2 boot loader. Stock Rom doesn't start and frp lock. How you fix it ? Thank you
Try this method

Samsung galaxy s8 bootloop after manual uninstall magisk 16 S.O.S.

hi, im new at the forum , and only that i want its to solve that issue with the bootloop after unisntall
what i do ! :
1.. buy and new s8 samgung galaxy exynos sm-g950fd
2.rooted usign this tutorial: youtu watch?v=XNznlTJJesc&t=290s
3. its works! twrp installed magisk 16 installed! , and then i put an app ass default with root .
4. uninstall magisk using the option (unintall from the app, and the other option uninstall too or something) because the video wouldn says to beware at uninstall magisk
5. reset my phone and enter to a bootloop.
what do to try to solve it! :
1. search a solution on youtube, not work, seek solution on xda forum that tooks me to the wiki of magisk and says: "try to do a rom recovery"
2. download rom, extract bl ap etc etc and grab odin 3.13 and flash ap and bl files
3. its works the smarthphone came alive,but the issues started further...!
what happen after this!:
1.cant use galaxy pay app(issued reported)
2.cant use secure folder app (issued reported)
3. your phone came from 64 gb to 16gb, i dont know why ?
i trying to install twrp but odin failed , and looking for more info, i found that flash everything will be a solution or use odin option nand erase and look for exactly pit file for my phone, but maybe its another way to solve this issues , anybody please!!! help us!!:crying::crying::crying::crying: (in the video you can see that this s..
happens to a lot of subs of that ch )
thank u 4 taking your time to read this i apreciate it!
pd: sorry maybe my english its some roosted xD (im from bolivia):good:
okay i know a few things,
Your galaxy pay app and the secure folder app will never work again, by rooting your device you blew a e-fuse that is Irreversible.
As for your storage decrease it might be because of a wrong file you flashed, check your version and see if it matches
As said above Knox is now triggered. Which means no more apps like Sam Pay, Health, secure folder etc.
There is nothing you can do from now. It is triggered when you rooted the phone and it'll stay like that for forever.
You should have searched about everything before rooting. Asked all serious and stupid questions.

Help with NFC Crashing - AT&T S8 Active

Hey,
Need some help. My brand new AT&T S8 Active arrived yesterday. Since I am located outside the US I'm stuck with utilising Odin to update the software.
The current version listed on the AT&T website was 5CSK1 and I was able to track down the update:
https://forum.xda-developers.com/showpost.php?p=81251867&postcount=743
It installed successfully, everything is going well however I am unable turn on NFC. The toggle found in the settings menu is off and when I attempt to switch it on it greys out for a few seconds then the 'NFC keeps stopping' error appears on the bottom of the screen.
I've cleared the cache/data for the NFC app - no luck,
I've performed a factory reset via recovery menu - no luck.
I've installed the previous build 5CSJ3 from: https://forum.xda-developers.com/showpost.php?p=80903399&postcount=187 with a factory reset straight after - no luck.
I'm currently back on the latest K1 build.
Logcat shows errors with 'libnfc_nci' and a 'Fatal Exception' for the 'com.android.nfc' process. And to top it all off the NFC app is draining my battery.
If anyone can help me that would be awesome.

ugh, the active line... there hasnt ever been much support for those. All you can really do is keep flashing the stock firmware and hope that the errors resolve themselves.
Side note: have you noticed how they stopped making the active phones? They were a dismal failure. All they are is the regular phone in a case that you cant take off :/

Might try redownloading a different firmware from a differ location. I had this issue on a lg back in the day the camera wouldnt work no matter what I always restored stock with one firm I had. And it ended up being a bad download. Another possibility is a bad NFC chip. If it's new I'd have it warranted
Thankyou, Thankyou Youdoofus and TheMadScientist for your advice.
Woke up early today (3am) with coffee in hand I tried again downloading the K1 and J3 builds; neither worked.
Unfortunately there's no alternative download for them... Google points to the XDA forums which seem to come from some Russian forum.
I've gone to an earlier build - 5CSI3 - https://forum.xda-developers.com/showpost.php?p=80505887&postcount=186 which works.
So it's not a NFC chip issue, yay. Now, just need to figure out what I'll do when the next update hits at the end of this month.

Yeah, it's working on the 5CSI3 build from October 2019, there's been two recent updates since then (and another will come at the end of the month). I don't know what's happening as no one else has reported this issue .
Just wanting to be on the most recent version for security and the annoyance of having data wiped every update.
Edit: Yeah, Odin v3.13.1 . No errors being displayed, all green.
This issue is very likely to be caused by 3rd party sim unlock or FRP removal and meddling with knox.
I have been trying to get around this problem and it seems it is either a security measure to disable nfc payments on triggering knoxguard or problem with modem.
this problem started after CSJ3 update afaik and only on some phones, if someone can explain this would be great.
Solution:
You will lose all data so backup is recommended
Remove your SIM card, re-install the firmware with ODIN and check Nand Erase auto reboot and F. reset time
Check your KG status(checking or prenormal) on the bootloader, and in settings>device care you will see Security is disabled and it crashes when you click it.
I also noticed the settings menu is weird with many broken options and dailer codes dont work anymore.
EDIT: Workaround Solution:
THIS IS FOR G892A ONLY who have problem with NFC after updating to builds after December 2019
Disclaimer: do at your own risk and can break your phone signal or system detected as rooted/custom
note: you will lose all data, ONLY check "Auto Reboot" and "F. Reset Time" in odin
1) Backup your data
2) Delete your google account, so FRP : OFF in bootloader (this can cause problems if not done)
3) Flash 5 firmware files G892AUCS5CTC1 (latest rom with march 2020 security) and get back to bootloader
4) Flash 3 files from G892AUCS5CSI3 : BL, CP and CSC
(odin will say PASS, but recovery will give error)
5) select wipe data partition then reboot to system
when the phone starts you will see NFC logo in statusbar means you are successful
if you get errors while using odin: flash combination file : G892AUCU5ASD1 if this doesnt work it means you have different problem (cable, socket, pc, bad chip)
i tried flashing CP file only and phone booted into UPLOAD mode, so dont panic if you get into UPLOAD mode just reboot with 3 buttons to recovery and start over

This issue is very likely to be caused by 3rd party sim unlock or FRP removal and meddling with knox.
I have been trying to get around this problem and it seems it is either a security measure to disable nfc payments on triggering knoxguard or problem with modem.
this problem started after CSJ3 update afaik and only on some phones, if someone can explain this would be great.
Solution:
You will lose all data so backup is recommended
Remove your SIM card, re-install the firmware with ODIN and check Nand Erase auto reboot and F. reset time
Check your KG status(checking or prenormal) on the bootloader, and in settings>device care you will see Security is disabled and it crashes when you click it.
I also noticed the settings menu is weird with many broken options and dailer codes dont work anymore.
EDIT: Workaround Solution:
THIS IS FOR G892A ONLY who have problem with NFC after updating to builds after December 2019
Disclaimer: do at your own risk and can break your phone signal or system detected as rooted/custom
note: you will lose all data, ONLY check "Auto Reboot" and "F. Reset Time" in odin
1) Backup your data
2) Delete your google account, so FRP : OFF in bootloader (this can cause problems if not done)
3) Flash 5 firmware files G892AUCS5CTC1 (latest rom with march 2020 security) and get back to bootloader
4) Flash 3 files from G892AUCS5CSI3 : BL, CP and CSC
(odin will say PASS, but recovery will give error)
5) select wipe data partition then reboot to system
when the phone starts you will see NFC logo in statusbar means you are successful

Hello There!..kind of new about this so..long story short..
Phone had Android 8, and I really love Night mode on Android 9, so...I've found BL, AP, CP, CSC, USER Data ROM for GALAXY S8 ACTIVE AT&T Unlocked, however..I am a little bit afraid of any NAND Erase.
I am not an expert, but I can tell you are. By any chance do you have any vide or graphic tutorial abot how you can perform these actions? It is very odd that I am unable to have any *# codes working, and lately, I've received this odd message about NFC Service has stopped, so...any graphic step by step guide will be highly appreciated it.
I've tried ....soft reset, then factory reset, then flash again ODIN (BL, AP,CP, CSC and USER DATA ) But I have no idea how to back up my data, and it will be very helpful to have G892AUCS5CSI3 as well.
Thank you very much for your time, I hope you can help me and I appreciate very much your time.
The one that I have is AP_G892AUCS5CTC1_CL16888298_QB29841048_REV00_user_low_ship_MULTI_CERT_meta_OS9.tar

USERDATA_G892AUCS5CTC1_CL16888298_QB29841048_REV00_user_low_ship_MULTI_CERT.tar
SOLVED!
So...I've followed the steps to install only BL, CP and CSC using G892AUCS5CSI3...however, the system started as usual, and actually did not work =(
RESOLUTION:
INSTALL THE FULL G892AUCS5CSI3. Worked as magic =)
thank you for the thread!!

You can backup your data with Samsung backup and restore to Samsung cloud or to your PC with Samsung's Smart Switch app.
As for tutorial I'll try to make one with images for the latest ROM G892AUCU5CTF4 dated 20-Aug-2020 with August security patch. I'll upload it later as I still have to backup my phone before updating.
Thanks!
Thank you so much!
Is it G892AUCU5CTF4 a estable versión for S8 Active? Or does it has any other bugs? I had to "downgrade" and now things are pretty cool, however, I would love to have the newest version. Thank you!

It doesn't have any bugs but some people have issue with flashing new builds, if you have this issue just install CSI3 build or earlier

It installed successfully, everything is going well however I am unable turn on NFC. The toggle found in the settings menu is off and when I attempt to switch it on it greys out for a few seconds then the 'NFC keeps stopping' error appears on the bottom of the screen.
I've cleared the cache/data for the NFC app - no luck,
I've performed a factory reset via recovery menu - no luck.
I've installed the previous build 5CSJ3 from: https://forum.xda-developers.com/showpost.php?p=80903399&postcount=187 with a factory reset straight after - no luck.
... And to top it all off the NFC app is draining my battery.

Same. I also tried CTA2 and CTL1. Everything after CSI3 has NFC crashing and excessive battery drain. I've tried multiple flashes on multiple phones.

I tried again downloading the K1 and J3 builds; neither worked.
Unfortunately there's no alternative download for them... Google points to the XDA forums which seem to come from some Russian forum.
I've gone to an earlier build - 5CSI3 - https://forum.xda-developers.com/showpost.php?p=80505887&postcount=186 which works.
So it's not a NFC chip issue, yay. Now, just need to figure out what I'll do when the next update hits at the end of this month.

I don't know what's happening as no one else has reported this issue .
Edit: Yeah, Odin v3.13.1 . No errors being displayed, all green.

Same here. I used Odin 3.14.1, though.

This did not work for me, not even with "Nand Erase" checked.

Same. The problem of the secret dialer codes not working parallels the NFC problem for me; that is to say that it doesn't work on any firmware after CSI3.

Same. I'm not sure where I originally got it from, but here's a reupload from my archives. I created a list of MD5 checksums if you care to check the five files for corruption.
