I rooted my galaxy s7 edge (snapdragon) and everything was fine and working except I couldn't get SuperSU to install properly. I would get the app screen, but nothing else. A couple of apps would show up (Root Checker, Flashfire) after I had run them but I didn't get the typical SU screen with settings. I'm not including the softwares used (I did have debugging enabled in Develper options on the phone, secure boot unchecked, and the correct Samsung USB drivers installed) because I don't think it's relevant to my question - if not so, let me know and i'll be glad to provide the info - I'm a newbie at this so please bear with me). I read about the warning to not update the 2.74 version of SuperSU but then I saw the update beta for 2.77 so I tried that. It appeared to run ok; I could see all the commands being executed and then ending and then the phone rebooted, as it's suppose to do. This is when the problem emerged; a screen came up saying "start up failed" and at the top left of the screen it said 'Custom binary blocked by secure boot (boot.img). I rebooted to TWRP recovery mode and tried rebooting which again resulted in the start up failure screen. I then tried the wipe data\factory reset setting and the same thing happened. I then booted to maintenance mode and got the warning screen about a custom OS installation can cause problems but if you want to proceed press volume up key which I did and got the usual Downloading page. At the top of the Downloading page I noted it said, among other identifying info: Odin mode (high speed), FRP lock: off, QUALCOMM Secure Boot: enable, and Secure Download: enable.
But, when connecting the usb cable to the phone and pc, my computer (Win 10) doesn't even see it. Not sees and doesn't recognize, but doesn't even see it. I tried a second USB cable and different ports but got the same results. I tried a second computer and got the same thing.
I am guessing that if I could still access the phone to run rooting apps I could get past the lock. If not now, maybe later on when someone figures our a way to do so. But without a working connection to the phone I am helpless. I am wondering if Verizon disables USB intentionally, so that the phone essentially becomes useless. Or, is it a coincidence and perhaps there is something wrong with the usb hardware.
Is there a way out of this other than having to pay for it to be fixed (which Samsung won't do - I called - and maybe Verizon not either).
Thanks in advance -

I'm trying to enable Samsung Pass (Under Settings -> Lock screen and security) but keep getting "Your device has been rooted. Samsung Pass cannot be used on rooted devices for security reasons."
Well, my device is NOT rooted!!! I can use Samsung Pay - can't use that if I'm rooted, can I?
The only thing I can think of is that I enabled developer options, but that's been turned off.
Obviously rebooting doesn't help.
Any ideas?

Hi all,
:crying: - Looking for a way to get my Mi Note 2 back to life!
This device has never been unlocked or ROMed before (although it has been re-flashed successfully via Xiaomi's own pushed updates).
It is running MIUI 10.0.something (cannot access menus to verify exact).
The problem
----------------
I did a standard factory reset on the phone.
Once restarted, it takes you through the normal setup screens such as 'language', 'region', 'wifi network' after which I am given the option to select "copy your data from an old phone" or "set up as new", no matter which I select, my phone goes to the next screen which shows "Checking for updates". Here it stays - endlessly...
What have I tried?
----------------------
I have tried a different wifi network but it does the same.
I have also tried selecting "copy your data" instead of "set up as new" but it does the same.
Thoughts
------------
I thought I would try to install a new stock ROM to see if that would fix the issue. However, in order to unlock with the Mi bootloader unlock tool (and then use their flashing tool), apparently to do this, I need to enable something under developer options - clearly impossible when I cannot get to any android menus.
The phone *can* be re-started into the fastboot screen but does this help me at all?
On the MIUI website I noticed the following in the tips and tutorials forum: How to install a MIUI update without unlocking the bootloader: https://en.miui.com/thread-3852597-1-1.html
The above got me slightly excited before I realised that I have no way to place a ROM into the ‘downloaded_rom’ folder in the internal storage of my device (as the article instructs). Note that the reason for this (on my phone at least) is that although a Windows explorer window does open when I connect the phone to my laptop, it is empty (i.e. you cannot see any files/folders in it). BTW - I know what causes that specific issue as that bug was present in the device ages ago - basically, the phone seems to default to be in USB charge mode and in order to see the folders in Windows Explorer, you have to go into developer options and manually change the USB mode and then change it back to MTP mode. Once that is done, you can see the files/folder structures. However, I cannot get to any developer options as I cannot get to Settings at all.
What can I do?
------------------
So my burning question is this: How can I re-ROM this theoretically 'working' device, given the above constraints?
Is there any way to do anything while the phone is in the fastboot mode perhaps?
Is there some method maybe used to recover a bricked device that I could employ here?
Thank you for any help offered!
Cheers!
I have a samsung galaxy a6 tab and it has knox which prevents me from installing apps , prevents usb debugging and factory reset .. i cant even go into the download mode , cant deactivate it from being a device administrator,, is there is any way to remove it or factory reset the device to be able to use it?

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.
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
