As I said earlier I would like to get temp root for Docomo Fujitsu Arrows NX F-01F and this CVE is the one of several vulnerabilities which I could use to pull out boot block. I expect that boot image to be used in iovyroot later. No any other root methods work for my device. I tried almost everything (KingRoot, Towelroot, eRoot, vRoot, KingoRoot etc.).
