I Have a Samsung Galaxy A30 (SM-A305F) running Android 10. It is locked by the MDM or Knox from Samsung. As i boot the phone it automatically opens the Knox Enrollment Service and also Launches an app "Samsung Finance Plus". The knox verification fails and it locks the phone straight away. No other app, i literally mean no other app can be opened. Whenever you would try to open any app, it gives a message "Security policy has blocked the app". Here are some other major issues.
1) I can get into settings through the notification panel. I can get the developer options but the "USB Debugging" option is permanently greyed out. No matter what i do, change date time etc, it simply never comes to life.
2)OEM Unlock option is not visible in the developer options. *Though i can get into the Download mode or Boot mode by pressing the volume up and down buttons at start.
3)In download mode it says "FRP Lock = Off, OEM Lock = ON(L).
4)Factory reset is possible from Stock Recovery, but after resetting and finishing the setup it would again get locked and wont even allow you to open the playstore. Same Knox Enrollment Service comes up and blocks everything.
5)Only back button is availabe. Home button and recent apps button do not appear. I tried to turn on the onscreen navigation bar and when i use it i get a message "Security policy restricts the use of this key".
6)In settings, knox enrollment service and samsung finance plus apps cannot be Force Stop or Uninstalled. They are also device admins and the option to deactivate thier admin status is greyed out.
7)I tried to Flash TWRP in download mode but i get an error message saying "Custom Binary Blocked due to remaining installment balance"
8)However i can get into the phone and install apps with a trick. I can reset the phone and use it without finishing the setup process by getting in through the keyboard settings. Through this route i can launch Nova or Apex Launcher and install apps and use them. But if i go back and complete the setup process, then again it gets locked
9)Package Disabler Pro is not working.
10) When i connect the phone to my PC, i t says security policy restricts PC connections.
