Some causes for the looping boot animation:

• Damaged “saved_variables.cfg”
• Other damaged configuration files (printer.cfg, moonraker.cfg, etc.)

Typical causes for the damaged files:

• No more space left on the filesystem
• Powering off the KlipperScreen by the switch without shutting it down first
• Incompatible or wrongly installed additional klipper macros

Some causes for a black screen:

• Updating the system without having the kernel and dtb file locked
  (That became unlikely after Armbian Buster got removed from online archives in spring 2024.)

Fixes:

• Always make sure that there is enough space left on the filesystem first by removing old gcode files (and then reboot the device).
• Clean up the saved_variables.cfg as shown below
• Do a factory reset using Sovol's armbian-update.deb
• Do a full reflash of the eMMC using Sovol's KLIPAD50_IMAGE

Cleaning up saved_variables.cfg

• Open that file in the web frontend (found in the machine tab in mainsail or the configuration tab {…} in fluidd)
• Replace the content of that file with the following lines, then save and reboot the device:

[Variables]
filepath = ''
last_file = ''
was_interrupted = False

Factory reset using Sovol's armbian-update.deb

• Download the armbian-update.deb for your device:
