I'm using the "Saferoot: Root for VRUEMJ7, MK2, and Android 4.3" xdaforums.com/showthread.php?t=2565758 root method detailed, and it is taking a VERY long time (IMO) to transfer the files to the phone. This is a Verizon SCH-i545 on MK2. Kies sees the phone just fine, so I'm not concerned about drivers at all. One oddity that the cmd window shows was two lines of "error: more than one device and emulator", but that is followed by "[*] Sending files to your device..." And it's been sitting there for 30+ minutes. How long should this take, anyway? I'd ask in the original thread, but I guess I haven't posted enough on XDA to be able to do that.
