So I got my verizon lg g pad 8.3 vk810 model last week. Yesterday I rooted it and then unrooted it when a nav bar key went missing. The key was still missing so i tried to factory reset the tablet. When it tried to turn on, IT WAS BRICKED! it keeps saying "secure booting error! cause: boot certification verify" so I followed the traditional unblocking method for the lg g pad 8.3 vk810 but it won't go into download mode! I keep hitting both volume buttons and connect the usb but it just tries to charge expect it can't because its bricked! How do i get this tablet into download mode and unbrick it! If i can't will verizon replace it without noticing it was ever rooted? Please replay ASAP!
