Hi There after getting no reply to my former problem description i userd S1 flashtool to install Sony's latest
SoftwareUpdate10.7.A.0.228. Followed this link again to download and install Kingoroot & SuperSU from the links above (Intro).
Kingoroot sayes"Root sucessfully installed". But when using "SuperSU" Press button to begin, the progress-bar runs 75% and stops there endlessly.Above the progress bar it says "Cleaning up KingoRoot/KingoRoot artifacts" and stays endlessly! How to continue? What can I do bring it to a positive end?
Does anyone still read or follow this thread?My device is a Xperia Z (C6603) OS 5.1.1 CPU armv7l. SuperSU v.4.7
Please help!
