I have bought a NX few weeks ago. Everything is seems ok and my first experience is good. But only problem is that when I connect Pen/Flash Driver with OGT cable, top of of screen shows: External USB Storage safe to remove. Then i touched on menu-> settings->storage-> External USB Storage-> Mount USB Storage. But it does not work. I have tried it several times. It shows: USB Storage safe to remove Then I installed : Nexus Media Importer. Still it doesn't work. Next ,I have downloaded NX Firmware, Driver, Tools.rar and walton nx jelly bean2.2.rar. But failed to extract both .rar file. When I try to extract, it shows error after extraction of 90%. I have downloaded this farmware two times and still finding extraction error. pls help to resolve the issue. Sohel Rana
