After contacting Lego Support,
They confirmed the problem and they changed my EV3 brick.
I received it today and your firmware is working fine.
Thanks for your support.
Now it’s time to play (work) 🙂
sure I’ll be back to the forum not for an issue but for contributions 🙂
I’m following your post on facebook.
I’ll contact very soon Lego support as it seems a Lego brick issue (to be confirmed)
For Motor example the display is dimmed (I cant’t read what’s displayed I pressed only OK button) then the motors are running OK (meaning they do the same sequence as described in your video)
Here is some additional infos:
1 – I noticed that native firmware starts in this dimmed state, then when it switchs to the Menu it appears with no dimming issue. Is this normal with your Bricks Native Firmware?
2 – With Mono Brick firmware, It starts dimmed then the Mono Brick logo appears in a dimmed display too, then the Mono brick menu appears and stay in a dimmed display.
Please note that in between I tried other SD cards & I tried All images, and I have same symptoms.
Regarding your question, what happen when you write to your LCD etc…,
with Mindstorms programing blocks writing is OK.
With Monobrick firmware example I guess Color Sensor writes some text, but I wasn’t capable to see what is dispalyed it’s why I tried Motor example to see Motos running it was better 🙂
But regarding point 1, It seems that’s a brick issue.
Please find attached 2 photos, with native firmware(Screen_OK) & with monobrick firmware(Screen_NOK).
For info, I’m capable to connect Wifi and also I’m capable to run Motor example. (despite the hard navigation in the menu due to my display issue :))
Some auxilaury info may be it will help,
I’m using a sanDisk SD card with 2Gb, I repeated the SD bootable creation from another a mac using command lines as it’s well described in your tuto.
I started by img 2Gb, the EV3 hangs in starting phase whith a screan with text mindtorms + Starting.
I repeated the operation with 512Mb with same SD card of 2Gb, then the EV3 is running OK except the display issue :(.
I hope this may give some hints to this issue solving.

One additional info,
I used 512Kb.img in my 2Gb SD card (as 2Gb img didn’t fit in my 2Gb SD card)
