I am still having trouble getting ATV2 into DFU mode when Jailbreaking. I've downloaded the latest Seas0nPass (0.6.7 (23)) and have an iMac running 10.6.6. I have followed the links above, and while have no problem with iTunes recognizing my ATV, can't seem to get past the Seas0nPass screen of Waiting for device to enter DFU mode....
Here are the steaps that I am following:
1. Do not have iTunes running
2. Do not have ATV connected to either power or USB
3. Run Seas0nPass and wait until it prompts you to Connect USB and then press and hold MENU and Plan/Pause for 7 seconds
4. Plug in ATV2 into USB and hold down MENU and Play/Pause for 7 seconds
I have ATV2 flash every 1/2 second, but nothing else - iTunes does not launch, Seas0nPass does not say anything about detecting my ATV2 in DFU mode.
I have experimented with various permutations and when I have iTunes also launched (ignoring step 1) [this works if power cable is in or not in] at the same time as Seas0nPass, it does detect ATV2 in DFU mode. This is about as far as I have gotten.
Do you have any suggestions? I have tried every combination I can think of (hold down Menu down once plugging in the USB cable, not hold down menu down, with power cable, without power cable, iTunes running, not running, micro USB cable 1, micro USB cable 2, iMac, MacBook Air).... nothing.
