Samsung Galaxy S6 (unlocked) Manual update 5.1.1. UK

Hi, I have a Samsung Galaxy S6 originally on EE and I had it unlocked to 3. I am unable to do an update as via WiFi and I am presented with the following message, "The operating system on your device has been modified in an unauthorised way. Try downloading software updates using Smart Switch on your PC or visit a customer service centre".
I have been told that the unlocking of the phone has resulted in me not being able to use smart switch and that the phone is no longer connected to the Samsung servers.
The build number is LRX22G.G920FXXU1AOCY
I am using Android 5.0.2. at the moment.

If you're rooted you get that message.
Best thing to do is download your current rom again, flash it with odin and that'll restore everything to stock and allow the over the air update to be downloaded. (It doesn't wipe your phone)
Alternately download the latest rom for your model and flash that in odin and it'll update it.
Not that there is no (easy) way to root 5.1.1 without tripping knox.

How do I know if my phone is rooted or not?
Are there any obvious signs that will indicate whether or not the phone is rooted?
If the phone is rooted, where can I find the correct rom for my device and what are the steps to carry out this process?

AT&T Galaxy S6 Reactivation Lock

I recently bought a Galaxy S6 (SM-G920A), that has been factory reset and has been Samsung Account locked. I've done a lot of research and can't find a method that works for me to recover the phone.
Most recently, I flashed the combination rom (G920AUCU7ARA1), hoping to maybe achieve something by enabling usb debugging, but I'm not sure where to go from there or if it's even possible.
Also, I can't remember what exact firmware was on the phone before flashing the combination rom but it was on 6.0.1. Is there anyway to find out what firmware I was on? Can I just re-flash any firmware back onto it as long as it's 6.0.1?
Edit: Also, the combination rom is 5.0.2, so could I downgrade that far? I've read something about the bootloader version preventing that but since the combination rom is already this version wouldn't it make sense that I could install the same version of original firmware?
I've spent pretty much every hour I've had off work for the past 3 days trying to figure it out to no avail. Any help would be very much appreciated. Thanks.

I've seen/read multiple times about a bluetooth headset bypass by accessing voice assistant. Can anyone confirm on 6.0.1 G920A?
I should also add that I don't really mind if KNOX is tripped or whatever. There's no warranty anyways and that's all KNOX is for, right?

So, I flashed G920AUCS7ERA2, which is the newest firmware available. For some reason this was the only firmware that would work with odin - I'm guessing because of the bootloader version of the combination file being '7'.
Anyways, bluetooth doesn't work with the emergency call and also talkback isn't available, it's been replaced with voice assistant.
Any way I can downgrade to enable bluetooth or anything that would work? I'm honestly desperate at this point. I'm out $100 for the phone and the pawn shop can't give me the information for the original owner. Am I screwed or can anyone offer any assistance?
I'm willing to pay at this point.

I was able to downgrade to G920AUCU6EQCF. I don't know how but I am now able to enable bluetooth. I bought these, and they don't work. Google doesn't come up. Nothing does. Does it have to be a headset?

how to root android 7 on samsung s6?

i have been searching for hours and trying different methods and none seem to be working..
i am trying to root a samsung s6 g920i. it is updated to android 7.0
i have dev options enabled, debugging. the one thing i do not see on the device is OEM unlocking option.
so far ive tried odin3, i selected the cfar_samsung_sm-g920i_zerofltedv_nrd90m.g920idvs4frc9_t0 file, and it shows me successful messages in the odin3 results. but on the device it restarts real quick. once it restarts, its like nothing happened. the device is still rooted and there is no super user app.
ive followed numerous videos and threads all over and cant seem to get this device rooted.
is the oem unlocking option not showing up my issue? also, i noticed when the odin was doing its thing and the phone was restarting, there was a msg showing on the top left that stated "recovery is not seandroid enforcing" then the phone would restart.
any help here would be appreciated. it also looks like all of my samsung devices do not have the oem unlocking option under developer area (3 devices) so i am not sure what happened or what am i suppose to do.

Long Shot, but .....
Similar issues with a G9200 (Hong Kong version, dual SIM). You COULD try downloading Samsung's CROM.APK from the Play Store and see if you can unlock the bootloader that way. Are you by chance running recent Nougat on the device? My suspicion is that the Nougat kernel has been tweaked to disable the known rooting / custom recovery approaches. Areal pain in the butt. My next step with the 9200 is to see if erasing the NAND via Odin will allow me to flash an older MM build (I don't care about the data) root it, TWRP it, and put a decent ROM in place of stock.

Odin runs on a PC under Windows. (Saying you downloaded it to an SD card made me think you were trying to run it on your tablet.)
Try to use the Search function on the site. There's probably a thread on rooting the S7 Edge. There's definitely a thread on Magisk.
Here are the Magisk installation instructions.
Don't start with "I don't know anything, somebody tell me how." Read a lot of posts, at least learn some words.
Was I wrong to assume you want to root your tablet? What made you decide you wanted Odin? What is stopping you from Googling "unlock"?
Before you do anything destructive, find and download a copy of your current ROM, so you'll be in a position to recover. You can test burning a ROM without unlocking the bootloader, as long as it is an official Samsung-packaged ROM.
Good luck.

Well, you can't. Odin is an IBM PC program that runs under Windows. It is used to ship ROM files to a Samsung tablet. The tablet must be in "download mode".

Find the S7 Edge forum for help unlocking.
Odin is not part of unlocking. Odin is for downloading software to the device. I think you can use Odin without unlocking -- you will only be able to flash images. You could try flashing a stock image for a different language, just to see if it works. (Pick a language you think you will understand well enough to see how to change the language back to your preferred language.)
A separate step, with no reference to Odin, is unlocking. I think it is usually delete any Google account you have attached to the device, enable Developer Options, enable "bootloader unlock" in Developer Options, reboot to recovery or download mode (I'm not sure which), expect some message like "hit Volume Down to unlock" (could be Volume Up), accept that it will wipe data.
Once you are unlocked (verify by booting Android again, and checking the Developer Options to see if the "unlock bootloader" option is still enabled, but is now greyed out), you can try using Odin to download non-stock software. In particular, it is at this point that you might try to flash a Magisk-patched software to try to install Magisk. With Samsung, as of when I did it, installing Magisk will again require wiping data, so do not spend a lot of time configuring your device between unlocking the bootloader and installing Magisk.

one can't bypass FRP lock on Samsung devices. what you try with Odin3 is impossible, it won't reset FRP.
find another method for that model, there exist some cheats on YouTube

Question Return to Stock?

Good Morning Everyone
As the title suggests, i am looking to return my S22 Ultra back to stock.
i was on beyond rom for a bit, but too many apps complaining that my device was rooted has forced my hand to return my device back to stock once again.
I flashed the stock rom via odin, then locked my bootloader and wiped all data.
However i am still getting messages that my device is modifed.
Anyone got any ideas how to can truely return to full stock?
Thanks in advanced.
And yes i did do a search on the internet before asking, but i have been unable to find any advice outside of what i have already done.

happend to me, too. But only on the latest firmware. When I flash an older firmware, it won't appear. But after updating again to the latest ROM the message appears

Cheers mate. I'll give that a go.

Also note that if the device was rooted then you triggered the Knox flag and that one CANNOT BE RESET, it's an "efuse" (a hardware component that once changed it's state can only be reset by replacing it, i believe you need to replace the entire motherboard for that).
So, if the application checks the Knox status it will fail.
Here are a few apps that i know that will not work anymore :
- Knox itself (and any app that uses the Knox library/API )
- Samsung Pay
- Samsung Health
- Secure Folder
A few years ago I also had a banking app that failed to worked with a Knox flag triggered (on a Note 8), but after an update it allowed me to use the phone as long as i didn't have it rooted.
