How to unenroll knox guard?

[A103]

I have a Galaxy Tab A7 T500 bought direct from Samsung which is giving an error of 'enrolled knox guard prevent flashing factory binary (vbmeta)' when trying to flash a new firmware image.

How do I either unenroll or disable knox guard?

@A103 Hello, try resetting the device to factory settings! Greetings

Hi you need to enable oem unlock to get passed the bootloader.

I have done a factory reset from the recovery menu, still get the same error when trying to flash the rom

I had done the oem unlock when I first flashed a rooted fw (it previously was rooted, then a week or so later after a reboot it started to give the vbmeta error, which it now also gives everytime I try to flash the fw)

I then flashed the stock fw back on to it, but ever since then I have been unable to get the oem unlock option to appear in the menu.  In download mode tho, it says that it is unlocked.

Hi, I'm sorry about this but we do not discuss rooting or any other modifications which may invalidate someone's warranty. Same goes for Magisk.

I would suggest going back to the site you downloaded the rooted firmware and see if others had problems and whether there's a solution. As an alternative, take a trip iver to XDA Developers. There are some very knowledgeable people over there.

Best if luck, sorry we can't help 😔
