Using the stock image and animation is working perfectly but when i try the custom image/animation it just showing black screen.
all the image i tried are 168x120 and less than 1mb

firmware version: 0205

Same issue here. Size is correct but image just shows black. Meanwhile default stuff all works. The custom banner also has issues.
