I have managed to break the nexuses screen, it works in some parts but overall doesnt function well. I am getting a replacement but I need to relock the boot loader and unroot it. I tried to flash stock but adb wouldnt recognize my device so I rebooted into recovery and it recognized it. It wiped it then restarted but then couldnt find the device, I am now at a loss, I only have the bootloader available and my computer doesnt recognize the device, how can I flash stock back? and BTW I dont have any recovery either it wiped the entire device. Am I screwed or can I fix it?
