Display UI on Waveshare 3.5 inch TFT

[gattonero]

And why not using the latest 6.7.1 Moode?
try first to install your hdmi screen without installing the driver.
...
it will not be touchscreen at first.

Thanks for your reply. I study your config.txt first.

I use Moode Audio 6.7.1 and 7 hdmi waveshare touchscreen work well. Local UI is very good design.
Now, I got problem in 3.5 SPI touchscreen.  This is a process full of fun and tears and the only problem is I am still in the process.

Hello

Newbie here.

I have the Adafruit 3.5TFT installed on a RPi3, with a nicely working Moode (release 7.10) that I've been enjoying for about a week. It's all working fine, minus the display.
The screen I've received yesterday, I've been trying to install with the usual procedures, then tried the ones from here: https://cdn-learn.adafruit.com/downloads...rry-pi.pdf, to no avail.
I 've used the code

Code:

cd ~
sudo apt-get install -y git python3-pip
sudo pip3 install --upgrade adafruit-python-shell click==7.0
git clone https://github.com/adafruit/Raspberry-Pi-Installer-Scripts.git
cd Raspberry-Pi-Installer-Scripts

followed by

Code:

sudo python3 adafruit-pitft.py --display=35r --rotation=90 --install-type=fbcp

All went ok.
Then I'm asked to reboot, which goes on, but when I reconnect Putty (I've created the blank SSH file in the /root) it's a new session and the command that follows

Code:

sudo python3 adafruit-pitft.py

which is supposed to allow me all the config, no surprise it gives me:

"python3: can't open file 'adafruit-pitft.py': [Errno 2] No such file or directory"

So nothing else happens.
The screen has always stayed white never showing anything... at least I know it powers up and it's something related to the OS and not the Moode Audio release.

Anything particular I should look for? I understand that my poor knowledge of the commands doesn't allow me to understand the process so I'll be very grateful for any help, surely I've forgot something form the start!

thanks!
