Brightness controller (No Controller Detected)

That all sounds like you're doing it properly. The latest image should have the I2C all set up already. If you are able to SSH in or hook up a keyboard, let me know. I have some commands that I'd like you to try...

The first would be:
ls /dev/i2*

That should list the i2c busses. If there's nothing there, that would definitely be an issue. If there is something there, it should be like /dev/i2c-1.

I don't recall offhand if i2cdetect is on that image. If it's not, you might need to install it with:
sudo apt-get install i2c-tools

After that, you could try:
sudo i2cdetect -l
sudo i2cdetect -y 1
sudo i2cdump -y 1 0x62


Let me know if you could try those.
