i am trying to get rid of bootstrapper and everything i have ever done with rooting. I used the z4 root a while ago and i recently went into it and choose unroot i then went and tried to uninstall bootstrapper but it of course didnt work. i tried to follow directions on the internet but couldnt get it figured out. I then did a factory reset; that didnt work so i formated the sd card and that didnt work. I dont understand why my phone isnt exactly the way it was when i bought it by now but can someone help. can i take the sd card out put it in aa card reader and plug it up to my computer and get rid of bootstrapper somehow. please help im desperate ill do anything.
