Screen get stuck on blank ater update

Ender Series Creality Ender-3 S
1

Hello,

I have an Ender 3 S1 with an STM32F103 chip, and I recently performed a firmware update using the wrong software meant for the STM32F401.
Now all I get is a black screen. How can I undo this?
I have tried various solutions, and I always get the blue update screen, but nothing happens afterward, and the screen remains blank.

Help, I’m just a beginner in 3D printing.

Maybe this will be of some use to you?

It took some effort, but I have the display working again, and it’s functioning now.
Thanks for the link; I had already read so much, but I missed this one.
