I'm trying all which ways to Sunday to Volt my LG volt. I got for my wife for Christmas. Towelroot doesn't work, so I tried I guess the "manual" method. I downloaded IOroot and ran the Batch file that runs the adb commands. The unit boots into the "diagnostics mod" I select "Load from ADB", then the USB disconnects and I get the message "Unknown USB Device (Configuration Descriptor Request Failed). I have downloaded and installed the LG volt drivers. I even downloaded and installed the Android SDK (as per other instructions). I tried putting the update zip file within the IOroot onto a sd card, then loading it from sd, however I get some sort of message "Unable to mount SD". I know for fact that the sd card is good because I've formated it to FAT 32 with the correct sector size using mini partition and the phone reads the card and I even was able to backup the phone via LG backup. But It doesn't seem to work when I try to load from SD.
