IO2CAN v1.0 on rPi 3B+ with BTT TFT35 SPI

I have followed the (scarse) instructions here and trying to get this running but I get stuck at getting UUID. I bought IO2CAN with TFT35 to get a touchscreen on Klipper but after struggling so much and having a faulty BTT Pi 1.2 sent to me because after couple od minutes a smoke came out of the board, no real support from BTT (opened a ticket and did not get a real response for 5 days now) I am really starting to wonder is BTT a good company/product to deal with (and if you search a litlle bit on the internet you will get the picture).

So I would be really happy if somebody has a happy story, has made it work and wants to share their story how she/he uses Klipperscreen on a BTT TFT35 connected on a rPi 3B+ via IO2CAN.

Have a nice day.
