i've followed the steps mentioned earlier (i pasted it below) but nothing happens on my screen.
i see a few people got it working again but even though i've followed exactly as instructed, none of those things explained his posting happens to my computer screen or itunes, therefore i cannot do anything to downgrade my apple tv 2.
can someone help me to fix it, please ?

Step 1. I downloaded the correct restore file to my macbook pro.
Step 2. I then unplugged all cables to the AppleTV.
Step 3. I logged into iTunes on my macbook pro.
Sept 4. I then used a micro USB cable that came with my WD external hard drive plugged it into my macbook pro then AppleTV. The restore screen came up automatically. I pressed option and store at the same time. I was taken to the screen to find/use the restore file that I had downloaded in step 1. I'm happen to say everything went smoothly. iTunes confirmed that the restore was completed.
Step 5. I then connected the HDMI cable and power cord to the AppleTV and went through the AppleTV set up. I'm back in business! I hope this helps.
