My display looks buggy after updating to the latest firmware (Ender3-V2-Stock-20210830.bin). It’s not the blue screen with clouds, it’s just that the icons don’t show and some text is cut off. It is still navigable. I did the update for the display and it still appears buggy. Anyone else experience this?
Thanks,
Matthias

Downloading the _latest_ update to the display firmware fixed it. [Configurations/config/examples/Creality/Ender-3 V2 at bugfix-2.0.x · MarlinFirmware/Configuration](https://github.com/MarlinFirmware/Configurations/tree/bugfix-2.0.x/config/examples/Creality/Ender-3%20V2)

Continue with this screen bug, without icons and crazy words.
**I upgrade LCD with this:** [https://github.com/MarlinFirmware/Configurations/tree/bugfix-2.0.x/config/examples/Creality/Ender-3%20V2](https://github.com/MarlinFirmware/Configurations/tree/bugfix-2.0.x/config/examples/Creality/Ender-3%20V2)
**Use this firmware:** Ender3-V2-BLTouch-20210910.bin
What is the best way to solve this?
I`m try to find a old version to downgrade but not found, any idea?

Use the DWIN\_SET files from the link you quoted to update the screen.
The procedure can be found in item #4 of the FAQ:

It’s likely you are not following the instructions properly, or you have not prepared the SD Card correctly.
Make sure the DWIN\_SET directory is present on the SDCard and you use the video in the FAQ item as a guide.

Works fine!!! I hadn’t done the formatting SD Card step.
