CR-10v3 Bltouch installation error

Hey everyone,

I was attempting to install a bltouch sensor on my cr-10 v3.
During the installation I connected the cable backwards (on the board side) and after turning on the printer I immediately smelled something burning.
I turned the printer off quickly and reversed the connection (because I also noticed the bltouch did not light up the first time).
When I turned the printer back on it worked as normal and I could move all the axis and do basic configuration.
However, half of the LCD screen looks dimmer and now I can’t connect it to my laptop to upload a new firmware.
What could I have damaged with the reverse connection?
And are there any suggestions on how can I upload a firmware?
I already tried creality slicer and cura.
Thank you…

Update:
I noticed the dim screen issue is only when the control box is connected to USB only but when I turned the main power on everything was normal.
I managed to upload a new firmware using Prusa slicer and everything seems to be in order now.
Except I have been trying to get a level bed for almost 2 days now with no luck but, that is an issue for another post.
