Looking at the specs, you don’t need to do solder any resistors as it has the SSD1306 driver included.
Just the 4 wires, should do the trick.
Just make sure they didn’t twist the SDA and SCL.
So you can try by swapping them. It won’t hurt the Pi or OLED.
I had the same issue, but installing the plugin MPD-OLED did the trick.
Also check if you have not more than 1 I2C port enabled. With the commands
sudo i2cdetect -y 0
sudo i2cdetect -y 1
sudo i2cdetect -y 2
sudo i2cdetect -y 3
The OLED address is most likely “3C”
Pi display
Pin3 (SDA) SDA
Pin1 (5V) VCC
Pin5 (SCL) SCL
Pin14 (GND) GND
