Issue with the 2.8" screen (white screen)

[toxicooow]

Hello, i have a issue with the screen, when i'm following that tutorial below, i keep getting a white screen on the LCD screen
https://github.com/recalbox/recalbox-os/wiki/TFT-Screen-SPI-Bus-(EN)
I'm using a Raspberry Pi 3 along with a PitFT 320x240 2.8" Touchscreen resistive.
I'm not sure if i did a mistake in the Config.txt file, but here what i have:

#Smallscreen

dtparam=i2c1=on
dtparam=i2c_arm=on

#uncomment if you get no picture on HDMI for a default "safe" mode

#comment to get jack audio

#uncomment for lirc-rpi

#if you plug your tv at the same time as your rpi and that the rpi switches from the hdmi or give a low resolution because tv had no enough time to initialize it

#uncomment if you don't want the rainbow at startup

@toxicooow this is plugged through i2c on GPIO, not another bus ?

@coincoin I have no idea actually, i have plugged it like illustrated in the picture.

Well, turnout i find out what was wrong, and the issue was my screen was defective, since it didn't work with Raspbian or Retropie with the configuration.
It was keep blinking but no image appeared.
