So first off, i know that Android L is a developer preview and would have some issues here or there. some apps would crash and what not, I got that. i have had L on my Nexus 7 since day 2 with minimal problems at all. Last night at work i turned my tab on to find a static screen and nothing worked. i could hear it unlocking, but it was just static. after about an hour trying to get some of the screen, it came too but with all the colors off and running extremely slow. When I say slow, I mean i would press an app and it would take anywhere from 3-9 minutes to pop up if at all. I can't get it to go into the bootloader to get back to 4.4.3 or anything. As of right now, this Nexus is rendered useless to me and I HATE THAT!!!! if anyone has any insight for me i would appreciate it. Thanks
