Hi guys, I made a fatal mistake and I need your help! I don't believe but I kind bricked my Head Unit so I need your help to back to my default configurations.
What I did to f* my HU? see:
I get into a secret menu from Settings -> About Device then tap Kernel Version -> OS Version -> Kernel Version -> OS Version -> Kernel Version -> OS Version.

I reduced the contrast to zero and unintentionally hit the back button. This caused me to be unable to see anything on the screen.
Now I need to go back to that screen and hit the
Reset SeekBar Values button. How do I do this if I don't see anything?
Now I just see a black screen, I can't see anything. Do I need to reset this setting, is there any way? I already unplugged the power and turned it on again but continued with the black screen. I can only normally see the boot image. I can even listen to music if I know where the play button is. I am using AGAMMA LAUNCHER.
I recorded a video so you can see how it is now:

HELP ME PLEASE!:crying:
Can you help me by recording a detailed video of your HU showing how I get to this "Display Color Adjust Settings" screen? I'll try to reach this screen without seeing anything, just following where everything is in your video!
How do I safely reset settings? (Hard reset would work? Like if I press reset button and clean data and cache, would work?)
How do I reinstall the firmware if I don't see anything on the screen?
