S8+ unauthorised system changes- the Saga - Samsung Galaxy S8+ Questions & Answers

Hi All
so i am tearing my hair out trying to resolve my issue with a new S8+. i have spent better part of 1 week trying to suss out how the heck to fix this, trawling through forums, web pages trying everything without success.
Background
i purchased a S8+ through a friend who went to china. the device was made the US markets and i live in southern africa.
As far as i am aware the device is brand new (friend purchased s8 for some1 else- no issues) and came with full packaging and box
when i came to setup the device after going through all the usual bits, i got the security agent login message "unauthorised system changes- please restart device" and this message keeps appears even after the restart
Attempted Fixes
1. Attempted to root the phone- tried using specified apps- Kingroot, kingoroot in an attempt to disable system notifications. failed to root
2. Root using Odin- after trawling through the internet i found root file CF-Auto-Root-dream2qltesq-dream2qltesq-smg955u
this failed- odin error
3. Attempted to reload stock firmware - downloaded multiple versions of andriod, learnt a bit about using the right firmware download- failed. error message to the effect binary code 2>1
4. sideload oero based on firmware: failed - error message unable to load as andriod expecting different file version- (sorry i dont know if this is too vague)
SUmmary
HELP
all i want is to get rid of the annoying agent login message and start using my phone
at this stage not fussed about rooting phone.
grateful if i could get some good advice on how to resolve this. i have trawled and trawled the threads and have almost given up on sorting this

when going into download mode the carrier is VZW so assuming the device was meant for V Wireless in US

I recently went through the same thing you are describing but with my Galaxy S7. I had to download software from Verizon, install the software on my computer. Start the software and follow the instructions. You will need internet access. USB data cable. Your phone (if it's anything like mine was) will need to be started in Download Mode before connecting to your computer. If you can't find the software on Verizon's website let me know and I will get the link from other computer when I get back home in the next day or two. Hope this helps. BTW this didn't help the ROOT situation. Currently still researching that as well.

Sounds like first stick firmware is wrong revision.
Oreo must be on a certain firmware lever before upgrade.
C.f. auto root don't work due to locked bl

Help with FRP Lock

Hello everybody,
I usually find my answers in the specific phone related forums. But this time I'm stuck.
A friend of mine bought a Samsung Galaxy J7 (SM-J700F to be specific) in India. After using his phone there he came back home to Israel.
His phone didn't worked here for some reason and he went to a phone lab which flashed his ROM to stock Israel ROM.
They called him in the middle of the process and asked him what was his Google account thet he signed to while the first setup. Unfortunately, he cant remember his email address.
I took the phone to try bypassing the frp lock.
After a small search I realized I need an otg cable, which I bought.
I received the cable (1.5 mounths wait) and tried the otg cable method with no success.
After some experiments I successfully managed to open the settings menu. Pressed factory data reset and after a restart it stopped on recovery menu with the yellow message "dm-verity verification failed".
Well, this is annoying. I realized I need to flash the stock ROM again(Dated 01/16). So I did And the message dissapperd.
Back to the FRP lock issue. I did the process again and it didn't stopped in the recovery mode this time and I could see the Android logo with a little erasing.. Under it. Finally I thought.
I was wrong.
The FRP lock is still there! Dammit.
It is time to pull the big guns.
I thought I will flash the OLDER version of the stock ROM. Dated 09/2015 I Understand google updated the FRP lock protection on January 2016. Is the downgrade OK? I don't know if a downgrade is possible on Samsung phone.
And if you have an idea how to bypass this. Please share it.
Thank you so much!

Samsung Account Processing Failed..... again

Previously I had a problem with kitkat in which samsung accounts lock you out and there is processing failed. There are ways to get around that until it was fixed in lollipop. Now this latest update marshmallow plugged the holes in Lollipop. For me after the installation of the latest Marshmallow, I got blocked out of accessing my phone again... (samsung account processing failed) even though I know my user name and password, it would not accept it just keep on saying processing failed.
Just so you know my specs is Samsung Galaxy S6 Edge SM-9250, bought in China, switched to Hong Kong firmware, currently boots into the 6.01 hong kong version which is an absolute nightmare because "google" is blocked in China. I had to use a virtual laptop wifi VPN to get it pass checking updates.
I was wondering, if it is possible to downgrade my phone from the 6.01 to lollipop 5.1.1 unfortunately Odin keeps on saying Nand write failed for my AP's that I've been using. So, is there anyway to "fix" this problem?
Been searching all over the web for a solution to this problem. It is possible to downgrade from Android M to any rom above C017, there are ways to get internet, browser, downloading apps working, however it is still impossible to create a new samsung account or use my old samsung account. This is strange because I can log into my samsung account on the phone's browser perfectly, just not the phone reactivation lock.
Does this mean my phone's IMEI have changed? If so, is it possible to use my old Samsung backup folder to restore my previous IMEI? Do i need the exact same ROM to do this?
Any help would be greatly appreciated.
Any assistance please? I need to get this phone working for work.

Custom binary blocked by FRP lock

Hi there,
I have a Samsung Galaxy Tab A6 (SMT-580) which I bought today. I followed this tutorial to install twrp, ultimately to root the device:
dottech .org/200476/how-to-install-twrp-recovery-on-samsung-galaxy-tab-a-sm-t580/
Everything worked fine and I was able to boot and reboot fine. Until I signed in with my Google Account. After trying to reboot, I get a black screen with the Samsung logo and a text in red saying: Custom binary blocked by FRP Lock. I went back to the store and they advised me to install Samsung Smart Switch to try and restore. In the Smart Switch program I get an error saying that the device is not supported by Smart Switch.
I can get into download mode, not into any other mode. The tablet doesn't start up at all. On the download mode it also says FRP Lock ON.
When I go back into ODIN and retry to install the from above TWRP image, it says operation failed.
Can anybody please advice? I am at a complete loss. Am I supposed to flash the original boot file? Where can I find that for my device? Will my tablet accept that, since ODIN didn't even want to flash my current TWRP image a second time?
P.S. I only read later that you are supposed to change the OEM setting. I didn't. Is that the cause of this issue, and if so, can I do something about it?
Thanks
Hi. Have you got it fixed yet? You need to download and flash stock firmware for your model and flash it in odin. Once it's done you have to enable oem unlock before you flash twrp. Let it be enabled as long as you you have twrp, root or anything custom.

ok, I read this is the place for noobs, so, I too got myself into a FRP LOCK on my Galaxy Tab A6 sm-T280. I use the tablet strictly for flying my drone for surveillance around the rural location where I live. It was having some connectivity problems, so I rooted it to hopefully get enough horsepower to run the DJI Go app. That didn't work so I did a wipe/factory reset, had a problem with the password, and here I am.
I am researching, and gathering the required tools to fix it.
I finally found some guides that are basic enough for me to understand.
I found numerous sites to download the stock rom, but not sure which ones are safe. Suggestions? Also, I am not sure about the country code for the firmware. I am in the USA, and I don't see it listed anywhere. Does it matter? This android stuff is all new and confusing to this old man. I am determined to get this tablet fixed, and would appreciate any and all advice. Thanks, Gary
edit: Will this rom work? : T280XXUOAPL1 using XAA for theCSC? Is xaa the default/generic for U.S.A. ?

Need Help With My S6 ASAP Please.

Hello wise people of XDA,
This is my first post.
I currently use an S6 G920F United Kindom unlocked as my phone and i have been using this phone for a long time. Now its past its warranty I decided to root the phone and see what i can do with it and get rid of the bloatware. Normally i either use KingoRoot or KingRoot but both failed so I searched around on the internet and came across CF Auto Root. After seeing it was successful for others i jumped on the bandwagon. I rooted it and everything was golden until i came across a problem, it would randomly turn off. This was random and infrequent. but not it happens like 5 times a day so i decided to flash a stock rom. For some strange reason Sam mobile wont let me download a stock Rom so after poking around the internet i have download a few stock roms however they always fail in Odin. Now my phone wont even boot as it says "error occured while updating use smart switch emergency recovery feature" so i go onto the Smart switch PC app and then it doesnt recognise. After 2 days of trying i haven't had any luck so I don't know what to so. Every time I try flashing something, when it fails i get some red text on the phone which I don't understand.
Someone please help me as I cant just buy a new phone and this is the only phone i have got. Any help would be very grateful and please don't hesitate to ask any questions.
Edit:
It says on the Download Screen:
Odin Mode
Product Name: SM-G920F
Current Binary: Custom
System Status: Custom
Reactivation Lock: Off
Secure Download: Enabled
Knox Warranty Woid : 1 (0x0500)
RP SWREV: B:6 K:2 S:2
(When it fails it says) SW REV. Check Fail. Device:6 . Binary: 5
Hopefully that helped.
Somewhere in the middle of the firmware version there's either S5 or U5, on the firmware you are trying to flash. On the phone either S6 or U6 is installed, and there's downgrade prevention. You need firmware with S6 or U6. By S6 I don't mean the phone, it is just a version code.
Generally look for the firmware meant for the phone's region, though on websites the displayed region might be incorrect.
If the cellular fails change the firmware or wipe data (not efs!!!!!).

What do I do? I have like 10 different "stock roms" claiming to be United Kindgom BTU at Android 7.0 but all are failing. And I do not know what you mean by S5/6 and U5/6. And now i get a different error message. When it fails it now says Binary: 1. I don't know what to do!
Thanks for the quick reply and appreciate the help.

The firmware version(s) look like this,
G920FXXU6ERF5 . If there is U6 on the device and the U5 is flashed, it won't work. There are a few firmware 'components' inside the zip or whatever, and all of these must have the same or a higher version in the middle. New firmware might require odin 3.13.1 but should not show this error.

U6/S6, "Device:6" is in the odin log so it's already 6 and won't return to 5.

samsung galaxy s7 custom binary blocked by frp lock

Greetings, ever since i tried rooting my phone, i knew something went wrong (i used cf autoroot).
So the first thing i noticed, i was asked to reset the phone or something similar to that, meaning i would lose all my data.
I tried to find a workaround as this had never happened to me before while rooting a phone, and someone had said that i was supposed to download twrp
and change some partition and then change it back. I dont remember what else he mentioned and what exactly i tried doing, i realised it was formatted either way and i had to start fresh. As i setup my phone i went and switched the oem unlock back to "off", as i did not wanna attempt to root again, but i hadn't realised that my phone was infact rooted sucessfully, leading me to my first error after restarting. "Custom binary blocked by frp lock", with absolutely no access to recovery mode at all anymore. Again, trying to find a workaround, i download some stockfirmware that i atleast had hoped was the right one for my phone, after a couple failed attempts of flashing with odin, ( i had gotten various different error messeges on download mode screen such as (REV Check fail device 7 binary 0 and others witch i cannot remember), now im getting a new error screen, stating that an error has occured while updating the device software. I cant flash twrp recovery as the frp lock is on, and the only thing i can guess is that im flashing the wrong firmware, but i cant find a matching code at all.
Its the following: sm-g930fzkadbt
IMEI: 35214310282955
on the back of the phone it says uk yateley, although the phone was purchased in germany.
Im not sure what to do anymore, any advice would be greatly appreciated.
PS: I have managed to get back to the old error screen with the custom binary info, this time with bootloop, by checking the deviceinfo box on odin
Yep you've now learned the hard way not to mess about and read the proper guides.
Anyway "dbt" is just unbranded german firmware. Download UK "BTU" and flash with Odin, it's UK unbranded.
FRP lock means you'll need to unlock the phone with the google account and password that was on it before you started messing about with it.
If you don't know the google email and password you need to read up on how to bypass FRP lock and it's a nightmare.

Thanks for your reply, just a question, will any btu update work? Should i download latest android version btu firmware?
(Also yes, it was stupid of me to try and do it quick but i had rooted 3 different samsung galaxy phones in the past without issues, either i did something wrong or it took something way too specific to do the job, perhaps the phone's unrootable, but thank you either way) :fingers-crossed:

You'll likely only find the last version of BTU think it was August 2019. It isn't updated officially anymore but it'll be fine to use.

OK so i thought it worked but i can only enter recovery mode now and download mode, but cant actually boot the system, it just boots up the battery screen whenever i plug the charger, and never shows the actual battery info, just the thunder icon. Formatting from recovery mode doesn't help either (Note whenever i launch recovery mode it says installing update, then says no command and brings me to the recovery menu) Any ideas?
PS: It fixed itself. Sorry for the pointless edit.
