[Bricked?] Can't get to bootloader after trying to unlock with NRT
So I have a nexus 10 32gb that I got yesterday that I updated to 4.4.4 and I wanted to root it so I could get some apps that I love to use. Here's what happened:
Everything was going smoothly with nexus root toolkit. I set up adb and all of the drivers. Everything with that was working and I made sure to check nexus 10 with 4.4.4 in the drop down. I press the unlock bootloader button and the device says it's going into bootloader mode, but it just goes to a black screen. Then a message pops up saying I have to factory reset if i'm on 4.4.4, but that never shows up on the tablet, so I just hit OK. Then the device supposedly reboots, but now it's stuck in a bootloop and whenever I hold down the buttons to go into the bootloader the screen will turn black and the device will vibrate once after I hold the buttons for a while, then it tries to reboot again and gets stuck bootlooping. Then I try the factory reset method through the nexus root toolkit, but fastboot fails to see the device since I can't get it into the bootloader! It also doesn't show up as the correct device when it is bootlooping and connected to my computer.
Am I scewed if i can't get to the bootloader? I don't know what went wrong. I just got it yesterday and assumed it would be super easy to root since it's a nexus device. :'(
Any help/ suggestions would be great.
