I tried to root my android device SGH 1337 (US version) using ODIN and ROM versions CF-Auto-Root-jfltecan-jfltevl-sghi337m.zip (i tried CF-Auto-Root-jfltecan-jflteub-sghi337m.zip also) . It goes well upto recovery.img and runs partly thru NAND Write start. In next step it fails with message "FAIL(Auth)". I understand it is authorization but I not sure what write access authorisation. The phone is in connected in "Download" mode. ODIN was run as Administrator.
