    I recently tried to flash my big box dual hybrid titan and now the LCD screen on the printer is blank (blue screen, no text). I've tried to flash it several times and power off/on does not fix the issue. I'm using the built-in flash utility in OctoPrint. I've tried the following to repositories:

    https://github.com/tohara/Marlin.git
    https://github.com/Alex9779/Marlin.git

    How can I recover from this blank screen?

    avrdude: 54452 bytes of flash written
    avrdude: verifying flash memory against /home/pi/.octoprint/data/bigboxfirmware/tmp/Marlin.hex:
    avrdude: load data flash data from input file /home/pi/.octoprint/data/bigboxfirmware/tmp/Marlin.hex:
    avrdude: input file /home/pi/.octoprint/data/bigboxfirmware/tmp/Marlin.hex contains 54452 bytes
    avrdude: reading on-chip flash data:

    Reading | ################################################## | 100% 5.71s

    avrdude: verifying ...
    avrdude: 54452 bytes of flash verified

    avrdude done. Thank you.

    Cleaning up build files....
    RM /home/pi/.octoprint/data/bigboxfirmware/tmp/*
    RMDIR /home/pi/.octoprint/data/bigboxfirmware/tmp/
    Done!

    Could it just be the screen misbehaving? The contrast adjustment on some of them is quite flaky and had to be adjusted long after installation because they suddenly stopped displaying anything visible.

    If Octoprint still has positive control (can move the steppers, control the heaters, and measure temperatures) I'd suspect it's just the display.

    OctoPrint says "Connecting..." so I don't think the Marlin board is responding anymore. LCD contrast was fine just before I hit the flash process.
