Pretty much all Samsungs have Knox. I do have the knox cleaner/reset for this device but for some reason I don't think that's what you need. If you can't get into download mode you can't flash in the Knox reset. From your description it sounds more like you are in some kind of FRP Binary lock. Or, are you sure you're not in Demo mode? Let me ask if you can use the device in any way?Are you in a bootloop. A bootloop is when you can turn on the device but it doesn;t load farther than the LOGO screen. If you turn it off can you access Recovery or Download mode (whether or not you can use it)? Are you getting redirected from them to another screen? Can you describe what you can do? Any and all symptoms you can list could help define your difficulty.

I'm having the same issue although mine is much worse it's from an app called netspark mobile it has device owner provisions and I cant do anything after disabling its accessibility options windows keep popping up continuously telling me to renewable them which will just close all windows and lock me out whenever I try to deactivate the device admin which is greyed out

Also me the same issue but tab s6 lite. Did anyone solve this ??.

It sounds to me like what each of you is talking about is third party security software sometimes used by businesses to prevent employees from installing unauthorized apps and to prevent people from seeing company data on lost or stolen devices. The only way I know of to remove that type of software is to have authorization from the original owner to have the software maker remove it.

Recover data from S8 with broken screen

Hi everyone!
I broke my S8 screen completely by dropping it (the phone is still working, not know if the touch still works).
I want to recover WhatsApp backup folder and DCIM folder (i had no backup service enabled, nor samsung account, nor google photo or gdrive), so i thought to go ahed through ADB. Anyway adb list no devices until i unlock my phone through pattern code ( i had no facial/retina/fingerprint mode set).
So i thought to proceed through download mode, flash twrp through odin and access adb through twrp. Anyway it looks like i cannot use odin to flash until i trigger on "OEM Unlock" in developer options which i can't do no more cause of the broken screen.
Is there another way to enable OEM Unlock which doesn't require touch input? Or is there any other way to recover my two folders?
A big thanks for everyone who could help
You can use an otg adapter and a mouse and try to replicate your pattern code and after your in just transfer your files. If you happen to have a second cell phone I would suggest you practise a bit on that screen first so you can replicate the exact movements to unlock your phone. Had an issue with my s6 edge and that worked like a charm.

If you don't know how to recover data from S8 phone, just use an Android data recovery software, it can help you recover data from an broken Android device, it is really simple to finsih the recovery process. And you can preview and recover the data from your broken phone, so that you don't lose these data.

Log into Samsung Find my mobile. Use your Samsung Account details to log in.
There you will see alot of options that you can perform on your Galaxy S8 remotely.
Use the remotely unlock my device option to unlock your device.
Then connect your phone to the Laptop or PC using data cable and recover the data.
Hope it helps.

S5 cant turn off reactivation lock

Hello
I was searching and trying a lot but didnt found any solution.
My s5 is not turning on so i cant turn off reactivation lock. I tried hard reset, didnt help. Tried root but r/l is blocking odin.
Please help

I'd do the next:
1. Get an OTG cable and a USB stick. Format the stick to FAT32 and throw any .apk file on it.
2. Download some 4.4.2, say, G900FXXU1ANCE and flash it with Odin.
3. Reboot to recovery and perform a factory reset.
4. Reboot to system and enter Setup Wizard.
5. Connect the OTG cable with USB stick attached. When the phone detects the stick you will see a pop-up window of file explorer.
6. Navigate to your .apk file (from p.1) and tap on it. You don't really need to install it, you only need a security request after your tap.
7. Tap "settings" and voila, you are in the security settings menu now.
8. Navigate to "reactivation lock" and untick it. You'll be asked to enter your Samsung account credentials or to register a new account.
9. Register a new account, log in to it an you'll be able to untick Reactivation Lock and disable it completely.
The trick will work on early 4.4.2 only.

It will work in any case.
There are other ways too.
Yes, a pendrive or something like a USB cardreader with a card, just to connect it as external OTG storage.
You are saying you cannot turn the phone on. What does it mean? What you do and what you see?

1. You should know that the first boot after a factory reset takes a long time, say, up to 15 min. I'd suggest waiting 20 min. and then make a conclusion.
2. If your phone freezes and restarts after a factory reset, it's a good idea to flash a stock ROM. Reactivation lock will not block flashing a stock ROM via Odin.
3. If your phone still behaves abnormally, it's more likely a hw memory problem (rather often for G900), not a reactivation lock problem. Reactivation lock would not prevent the phone from booting.
4. If you still interested in "other methods", have a look at this my thread. It's for SM-G900V and the files will not work for SM-G900F, but there are another files and the main idea will work.
But I'd like to say it again: seems, it's not your case.

1. I will try to wait longer time.
2. Where should i find stock ROM? My phone is in Telenor (Norway)
3. Beggining of the problem with my phone was that one day after turning phone on it came to samsung logo and start to scream ( wery loud noise ) and turned itself off. Since then it didnt pass trough samsung logo ever again. Then i started with factory resets and when it didnt help i tried to root it and put new ROM but all was blocked by R/L.

@bbsc
I have tried to put stock ROM and it didnt help. I was not sure which version should i use so i started with first one from the list. Odin says it was succesfull but phone is stopping now with recovery booting welcome page. It takes about one minute and the phone is off. I tried four versions of stock ROM and result is exactly the same.
Phone is not starting at all.
Should i try all versions of stock rom?

Hi,
I don't want to make you afraid but I was facing very similar problem and nothing helped but replacement of phone's motherboard at Samsung service centre -> my eMMc memory got corrupted for some reason.
Hopefully it is not your case but after reading your symptoms I wouldn't be much optimistic.

Any one is enough.
If you flashed a stock rom, performed a factory reset and the phone still restarts it is not a good sympthom.
I think, Many40 is right and it's time for a new motherboard.
There's nothing to be afraid of, it's just about $30 if DIY.
@Many40 @bbsc
Ok so i give up. I realy like this phone so i will give it to service for motherboard replacement since i have no idea how to do it by myself.
Thank you guys for help!
Cheers!

MDM Locked Galaxy Tab A

I have a Samsung Galaxy Tab A (2020, SN-T307U) that I got from work. It's an old Doordash tablet that Doordash didn't want back, so I'm trying to reset it and it's driving me crazy. I have followed so many tutorials trying to get this thing to work, I keep getting caught on something.
- Simply factory resetting does not work, gives an error that MDM does not allow it.
- I cannot put in the wrong password 15 times to factory reset, even though I get a warning it just lets me continue trying after 15 fails.
- I cannot enter the bootloader, rebooting to bootloader just reboots to the OS.
- I cannot enter safemode, same as above.
- I cannot enable developer options, so no OEM unlock or USB debugging. Tapping build number gives me an error that the MDM does not allow this option.
The device is recognized by Odin, can I just brick this thing and repartition from scratch? Can someone who knows what they're talking about walk me through that? I'm not really sure what I'm doing here, learning as I go over these last 2 days.
Hello,
I have the same exact same issue, have you been able to unlock it?
Thank you!
I can fix it remotely the last hope
Same Issue here,
Any one had any luck with MDM T307U. Please assist.

If you look at all of the previous post, it should tell you that no one has found a way to disable an MDM lock. Which is as it should be. Otherwise the lock would be useless.

That's not true as of today's date. (In the event this post is viewed after this exploit can be successful).
I am not taking credit and perhaps the op has discovered it. Anyway...
I am in Canada and noticed the carriers here stop at BL 8 while the USA has BL 9.
The unit i had was on BL 9 (csc TMB).
This probably works for Canadians on BL 8. I don't recommend flashing to BL 9 as that may affect your service or experience.
ANYWAY! This guide won't explain any prerequisites. They are adb, installing unsigned drivers, and you aren't able to use the device and are the owner
1) if not already, power off device with vol down+power and ensure battery is at least 50%.
2) enter recovery and factory reset. If you're having difficulty entering recovery, plug into your pc and as soon as you hear the audible disconnect, switch to vol up+power. Or jam on all three buttons for dl mode.
If in dl mode you can check firmware version and just flash it with bl, ap, cp and csc (NOT home csc). Use exact current version. Don't worry about userdata if it is USA
3) at welcome, connect wifi and imnediately go back to first screen. Don't use data sim
4) dl samfw app and on misc tab, check driver status and your pc will reboot.
*you must not have secure boot enabled
5) plug phone into pc. In the app, mtp and select youtube. If done right, click the pop up on your phone and navigate to chrome. Should be automatic.
6) search for vnrom frp. Once there download package disabler pro and notification app. They are side by side. Install notification app and set it up so you can swipe quick settings from top of screen.
5) unplug your phone from pc and plug it back in. Should be able to get back to the package app various ways to install it. Before install, turn wifi off. Now run package disabler and when it prompts for device admin, turn wifi on. It'll glitch a bit but should start.
6) locate samsung setup wizard. Don't confuse with the other. It'll have a green icon. Disable it and clear the storage. At bottom left, tap the back arrow and you should be back at final setup.
7) when asked to add samsung account, turn off wifi. Complete setup and don't add any accounts.
8) you should arrive at home screen. Your phone is re-plugged right? Good. Now turn on usb debugging and use the remove knox from the app. Done.
*i think i turned wifi on just before enabling debugging. I forget.
*if you are sloppy... you'll need to start over. You'll see, or already know
*you can do ota (if there still is any) but factory resetting or odin flashing will put you back to managed.

This method works up to step 7 for me. I can't seem to enable usb debugging before knox kicks in. With or without wifi. I'm experimenting to see if I can get past that step.
How to Remove MDM Control from Android?​For anyone suffering from this issue, the following are the steps to bypass Samsung Knox factory reset protection:
First of all, create a password for the device.
Make sure that your device is charged to an 80% or greater charge.
Next, you’ll need to go to Settings and Security Encrypt Device tabs respectively.
Set a PIN/password for your device.
After you have secured your device and it’s gone through. Reboot the device, and when it boots, it will ask you to enter a password in order to access your device to view encrypted data. If you type the wrong password 15-20 times (it depends on your device), it’ll wipe your device of any information and will restart and then appear like you’re registering as a brand new device after a factory reset.
Thats the 2th!!! Try it

MDM profile? Managed by IT SM-T597V

Hello,
I have a Verizon Galaxy Tab A SM-T597V.
The device allows me to factory reset and even used Odin to flash the factory ROM onto the device. I’ve even successfully been able to rush through the set up and access settings and enable USB debugging.
But no matter what if I go through the set up menus it eventually pops up and says “Managed by your IT department” and installs an app called “Hub.” The KG state says Prenormal and FRP Lock says OFF. OEM unlocking has never shown as an option.
Has anyone encountered this or know of an option to keep the device installing these programs during the set up screen?
Any advice pointing in right direction would be great!

Regarding Samsung Galaxy A5 2016 [A510F] FRP removing

Hello everyone.
My A510F device was bricked many years ago and the shop "service" that time said to me that the processor is "defective" - no chance to restore the device. Therfore it was sleeping in the shelf. Now - with a little bit more knowledge - I tried to re-animate the device. And I realized that the processor neither is dead...
After plugging the device to power the error screen (https://www.blogtechtips.com/wp-content/uploads/2017/07/An-error.jpg) occured.
The SMART SWITCH software did not help because there is no backup of that device existing anymore.
So therefore I unbricked it with Hagards "Frp HiJacker". Now the device is starting normally again - but needing the former google account verification.
FRP-removing by Hagards software failed. As well failed with SamFW.com FRP tool.
And restarting after factory reset the device statement occured that the reset was "not authorized" - so FRP failed.
And the normal Google verifying way does not work as well because the former account does not exist anymore for long time, as well as not the phone number anymore is existing. Restoring the google account by google support failed also - "not possible anymore" because cancelling account is "too long ago".
So I still need to bypass the Google Account verifivation for this device. And I do not really like to pay for FRP removing services like 4uKey & Co. because needing it for one device only.
Therefore my question:
So is there any other possibility for FRP removing in device download mode by using ODIN software?
Is there any flashing file especially for FRP removing?
Device details:
Samsung Galaxy A5 2016 [A510F]
Model SM-A510FZKADBT
CRC code DBT
Android 7
Accu battery reloaded 100% (...of course...)
The device is NOT rooted and as well I sadly have no access to any "normal" Android setting possibilities at the device. Therefore adjusting "OEM Unlock" or "USB debugging" is not possible.

I know it - but did not try this. Because it is another tool needing payment (like 4uKey & Co.) - but not really worth for unlocking "only" one device ...
Is it possible to ENABLE USB DEBUGGING from any external way? Because I'm not able to come into internal settings menue ...
