Some days ago i flashed CROMI-x 5.2.2 on my ASUS tf300tg... after some days i tried to transfer some files to my tab via USB data cable from my PC,,,, but my pc did not detect anything even no pop up in windows device manager, next day i bought new data cable but still same issue.. even though i have tried on several Pcs,, win 7/xp everything but nothing to see... My tab is as new ... Charging is perfect so there is nothing wrong with the USB port. All sorts of Asus drivers i have tried but still no luck.....today i managed to factory reset but still the same problem.....now root and TWRP both gone :crying:.......Any solution please
