Apparently, as of today (Dec 5, 2014), Towelroot and Stumproot do not support Boost Moble LG Volt software version LS740ZV4. Can anyone confirm an alternate method that has worked for this version of software?
Here's how I got my 2tb WD Passport to work with Nexus 7 (2013). I am rooted, but I've read this works with Nexus Media Importer regardless of root status.
I have a powered USB hub (BalanceFrom)
Plug the Nexus 7 into the MicroUSB port of the USB hub (where you would normally plug in the PC)...
