 +Or you can use: {{ :i2c_lcd.zip |}} from here, this worked with Raspbian Jesse. 
 +\\  
 +    2. Unzip the files: tar -xzvf LCD_show_v6_0_2.tar.gz 
 +     
 +    3. Change the the new directory: cd LCD_show_v6_0_2 
 +     
 +    4. Update System: sudo apt-get update 
 +     
 +    5. Install Driver: sudo ./LCD35_v (Pi will auto reboot) 
 +     
 +    6. If you want to use HDMI then: sudo ./LCD_hdmi 
 +     
 +    7. Run this before Pi Update: sudo apt-mark hold raspberrypi-bootloader   
 +     
 +    8. sudo apt-get update 
 +     
 +    9. sudo apt-get upgrade 
 +\\  
 +==== Note ==== 
 +\\  
 +Everytime I update the system with sudo apt-get upgrade, my LCD stops working and I have to do steps 2-6 again (actually, I don't do step 6 because I have nothing on the HDMI port) 
 +\\  
 +\\  
 +Now you should have a working LCD
