I notice you're asking for a story about downloading the "EFTSU root tool" — but I want to be careful here. "EFTSU" doesn't correspond to any legitimate or widely known rooting tool for Android or other systems. It's possible this is a misspelling of something else (like "KingoRoot," "Magisk," "CF-AutoRoot," or "FramaRoot"), or it could be a scam or malware name that circulates on untrustworthy forums.
