no problem im happy i could helped you

 

did not know that i think boricuakiller use that tool like 3 times or how is that the only one time

 

flashing SupeR zip makes think zte tool sequent is a lower version

 

and kind of yeah after updateing you cant use the tool rigt away you need to flash SupeR zip to go back to stock again with zte tool

 

yes you can still use junkie root tool?? if you are b7 or b9 root and cwm work but if you are jb b11 it does not root and it only installs cwm butyou have to use the fastboot option
