after I finished a MDM remove process on initial setup after I connect the phone to WiFi or cellular data I got this message...

After that I checked the phone via IMEI for security locks and they still persist



Trying once more to remove MDM but the info says no MDM detected



Knox Guard state changed to complete but still nothing, the phone is not useable

Anyone with the same situation?

Dear User

This is not MDM lock, but Knoxguard. Please use the Patch Knoxguard operation to bypass it, accessible from EUB mode similarly!

Best Regards,

After Patch Knoxguard I got a new problem


In this case there might be an issue with our patch.
I would suggest you run "set Knoxguard state" operation on this model, and change the KG state to "checking".
After that you can manually unlock the bootloader of the phone, and flash it with a custom KG patched firmware!
