J700H/DS FRP unlock


Hi. When i’m trying to remove FRP lock from the phone, z3x says:

Searching Samsung USB Flash Interface… detected COM130
Setup connection… OK
Reading PIT from phone… OK
Searching FRP lock… OK
Erasing FRP… OK
Searching Reactivation lock… not supported
Searching EE lock… OK
Erasing EE lock… error
Done with Samsung Tool PRO v.24.3

Any idea what’s wrong?
