i just sold my nexus 4 online and i need to ship it. i've unlocked the bootloader and rooted it and sold it like so. the buyer wanted it unlocked and rooted. i did a factory reset to clear my settings and files, however when i hooked up the nexus 4 via cable, i noticed that some folders from previous programs and data are still there. i deleted it manually but i'm not sure if there's anything else the factory reset did not get rid off. how do i remove all my previous settings and data for sure 100% while leaving the bootloader unlocked and the phone rooted? is factory reset enough? factory reset don't get rid off bootloader or root right? i noticed it did not but i just want to be sure
thanks
