After firmware update and restarting bullet -> "4-5 beeps" and display is black

Search for “Cold Reboot” and follow the instructions there. You may have to install a 2.5.x version of Roastime, but after you get the new firmware installed, you can upgrade to the latest version of the software. It sounds more intimidating than it is. Here’s a video that will help.
