[AC Question]

Greetings Every One ..

Today When I was Changing some Security Settings in My Phone, I Wanted to Activate KNOX, When I Clicked "Activate KNOX" , It Asked Me to Agree The License & Terms , So Basically i said yes.

After That, My Phone Restarted Automatically , It Show's up the Main Screen (Phone Logo & Android Sign at the end) , Not the Animation Samsung Logo, Didn't Showed up Yet.

Then i Wait 10-16 Seconds, The "Phone Logo & Android Sign" Was Sticky , Like Lagged !
& Every 10-16 Seconds, It Get's Restarted Automatically !
I Polled The Battery Off, Trying to Restart the Phone, Same problem

*Then I Decided to Reset to Factory Data ..
*I Followed Google Support Topic "How to Reset to Factory Data"
*When I Clicked "wipe data/factory reset" , It Give's me this Error:
(E: Unknown Volume "/spfd"==)

Please Help ! ..

Have you contacted Samsung? That’ll be your best bet since it seems to have happened as a result of Knox. This page should help you get the support you are looking for: Contact Samsung Support

Be sure to have the device model ready as they will be asking for that information.
