Yes. Both TFT Gizmo screen works as indented on the replacement board.

The original board I have, does not. The screen is lit up black and does nothing, no matter what i do.

However, the eInk display works on both board, which is why I now have 2 TFT Gizmo screen, thinking only the Gizmo was defective. I was wrong, now that both of them works fine on the replacement.

I refuse to flash that UF2 again, by fear it'll break the replacement board. I'll stick to Circuit python 7 and code only from now on

OK. Still no idea what could have happened to the original CPB.

Downloaded the UF2 you attached above and tested here and it worked fine.

I don't know what happened honestly. There's alot of variables that can lead to the board to malfunction. Maybe my board was defective to begin with.

I can assure you that after flashing this UF2 file, the screen part of that board stopped working, but not entirely since the eInk display works, and they have very similar pinouts.

Thank you for confirming that the UF2 works as intended thought! I guess I am just very unlucky

Yah, it's a total mystery. If it happens again, just respond back here and we'll try and figure things out. But at least for now you've got a working setup. :) have fun!

@ross49 would you mind bearing a bit more to see if we could recover the fault CPB.
- Could you double reset to enter BOOT mode, and paste contents of the INFO_UF2.TXT here.
- what is your OS: windows/macos/linux
