I tried to root my VZW SGS4 that fortunately came with the older VRUAMDK firmware. I followed these instructions. However when I got into ODIN mode and then opened up Odin 3.07 and connected the USB cable on my Windows 7-64 computer and PDA opened, SCH-I545_MD2_423399_Kernel.tar.md5, it failed. I tried again but this is as far as I got: <ID:0/004> Added!! <OSM> Enter CS for MD5.. <OSM> Check MD5.. Do not unplug the cable.. <OSM> Please wait.. <OSM> SCH-I545_MD2_423399_Kernel.tar.md5 is valid. <OSM> Checking MD5 finished Sucessfully.. <OSM> Leave CS.. <ID:0/004> Odin v.3 engine (ID:4).. <ID:0/004> File analysis.. <ID:0/004> SetupConnection.. I was stuck in that ODIN mode, none of the buttons would respond. So I popped out the battery and turned my phone back on normally and everything appears to be OK (and obviously still running VRUAMDK). Did anyone's initial attempt fail? I'm a little afraid to try again. Or maybe I'll update my firmware to VRUAME7 since its root procedure is much simpler. (Yes, I know it's not a full root since I can't install other ROMs ... yet). TIA for any advice you could give.
