@memreb and everyone interested in this to bypass activation and icloud, i'm a newbie and that's why i'm gonna make it as simple as i can.
This tutorial is for MAC only
first make sure libimobiledevice is installed on your mac
Connect your phone and jailbreak with checkra1n
Now here are the steps to follow after you have jailbroken your phone
1- open 2 terminal windows
2- in terminal 1 type: iproxy 4444 44
3- in terminal 2 type: ssh root@localhost -p 4444
answer with YES and use alpine as password
type: mount -o rw,union,update /
then: echo "" >> /.mount_rw
then: snappy -f / -l
it will show your snapshot name, copy it then paste it here:
snappy -f / -r NAME_OF_YOUR_SNAPSHOT --to orig-fs
then: cd /
then: cd Applications
then: rm -rf Setup.app
then: uicache -a
then: killall backboardd

ENJOY  
Special thanks to @memreb for guiding me through the most part of this. 
and ofcourse @GeoSn0w for all what he is providing.
