How To Guide FIX - "Can't create work profile because policy prevents custom OS"

[alp47470]

Samsung Galaxy Tab A7 Lite was distributed by our state government for promoting technology in the state. (JUST ELECTION THINGS)

Anyways, the Tabs are coming with Samsung Knox security which cannot be uninstalled, disabled, debloated with adb. The Tabs also come with restrictions by software to change wallpaper of lockscreen / homescreen and probably many other restrictions. (tracking and other stuffs) ALTHOUGH I MANAGED TO REMOVE THE WALLPAPER RESTRICTION (Screenshot attached) The Tab also comes with a work profile already by Govt.

The problem is that if you try to unlock the bootloader you can't boot by to the system because of the policies enrolled with the each device specifically. As of now i couldn't find any TWRP or any Custom ROM to flash and fix those things or ROOT or at least try to. Please hit me up if any development comes for the same.

[ THIS IS A TUTORIAL TO BRING BACK THE TAB TO YOUR OLD STATE ]

Now on to the steps to fix :
STEPS :
1. Lock bootloader by going to download mode (turn off the device, press both vol keys and connect USB untill the blue screen (download mode) pops up), then follow the menu.
2. Flash stock Firmware. After booting setup as usual and that's it. You should be back to your original state.
3. Force reboot to stock recovery and format data/erase data after flashing stock firware. (this setp is IMP if the step 1&2 didn't work alone)

My bootloader is probably locked coz the download mode does say OEM lock on
However even after flashing it with the stock firmwares I tried AUI3 and AUJ1 for the Indian region still can't seem to get past that issue

I don't have that option to press the volume up button longer and go into the boot lock menu coz the loader is already locked as shown in the download mode

If your bootloader is locked (Be sure) then perform a factory reset once, via stock recovery. That should solve your issue.

buddy sorry to be a bearer of bad news but your warranty is void (CHECK WARRANTY VOID 0X01), knox is preventing you from booting up. It can't be fixed by installing stock firmware. Either go to service centre (they might not accept the device due to its warranty status but if there is a way then they might take cash to fix it)
else wait for some other firmware and twrp. that's the only way

have you ever tried flashing stock firmware to your device?

It show warranty void etc in mine too after i unlocked bootloader probably because it's samsung's policy unlike other brands like OnePlus. After flashing stock fw and a factory reset via stock recovery you can boot back to previous state. Factory reset is important because because just locking the bootloader isn't completing wiping out system and when you boot back you can see previous WiFi already connected. That's why factory reset via recovery is important.

Bro. Why aren't you doing a factory reset AFTER flashing stock FW? Factory reset after flashing stock is IMP. Check OP instructions

Yes my issue began right after unlocking which was easily reversed once I locked the loader.
In your case you flashed a custom rom which caused the Knox to trip and thus causing further issue.
