EMG4 is version 2 efs format, same as GMK6, so unlock patches will not work.
Without a backup of your efs version 1 folder you cannot go back to a rom that patches would still work with.
If you have a valid imei then your efs folder cannot be empty, don't mess with it.
Note: This quote doesn't automatically apply to everyone, decide for yourself if it might apply to you.
