HI everyone....Somewhat of a noob here. I have rooted my share of phones in the past. Flashed a couple of Roms, etc... using CWM. I have an LG VK810 and it is unresponsive after root, and TWRP install. I cant get anything to boot...no Download mode, no bootloop, no boot at all. IS there a way to get this G pad up and running? Oh, the only thing that happens is...I get the windows 8.1 sound when I plug the usb cable in, but that is it. Fastboot/ADB will not recognize it. Neither does LGSupport,Flash,R&D Tool.... It looks like I killed it (Taps playing in background)
