[atv2] can't enter dfu

Hey there.

Been running on atv1 for years. Just bought atv2 and can't enter dfu for the life of me.

Have read numerous guides, and tried umbrella, greenpoison and pwnage tool. None get me into dfu, and the appletv never appears in iTunes or listed in umbrella etc. Apppetv on most recent firmware, works when connected to TV etc.

Connecting a USB lead I had lying around, the light does come on so I assume it's the right lead. Have tried a second lead and a second computer (iMac and MacBook air).

Any ideas anyone?

Cheers.

There are many posts/threads about jailbreaking in the off-topic section of this site.
Probably have more luck there as those guys really have the jb'ing down to a science.

Hold Menu + Down for 7 seconds
Hold Menu + Play/Pause for 7 seconds

If you have a mac, use Seas0nPass. Should be easier

It took me a while to get mine into DFU as well. Ensure you are on 4.2.1 by doing a restore in iTunes before you start the jailbreak.

See if this helps -

> I did not connect my power cable while jailbreaking.
> I used the Menu + Play/Pause way to get it into DFU.
> After restore, disconnect everything. Then connect the USB cable before launching greenpoison.

Good luck

Right - Thanks. Don't know why I didn't find the "off topic" section, it does have lots of posts, but none of them work for me :-( Might post there in a minute.

Don't want a tethered jb, so not interested in Seas0nPass.

I've tried the Menu/Down then Menu/Play options...

acoustique - I don't know how to restore in iTunes - it never sees the ATV2.

"Something" sure happens, I can hear the iMac "think" when I plug in the ATV2. I've managed to get the light to blink super quick, then a little less fast which some seem to indicate is "DFU mode", but greenpoison / tinyumbrella / iTunes still can't "see" the ATV2 nor actually do anything (greenpoison just goes back to "try again").

I've jb'd that many iPhones, right back to first Gen, really don't know why I'm stumped with the ATV2!

Have you tried another cable?
Was struggling with mine also, apparently the cable was a little loose, so it would kinda connect, but not correctly

I believe you can hook the ATV2 to your tv and network and restore from settings.
There is an option that says 'reset'.
Either that or 'update software'.
One of those 2 options worked for me.

If you attempted a jailbreak already, and your ATV2 is in limbo. The only clean restore is simply connecting your ATV2 with USB cable only, to your mac. Open up iTunes if it doesn't already, and click the restore button. That will get you back to factory fresh condition and you can began your jailbreak anew.

My advice is to put your unit into DFU mode first. Then run the jailbreak program. Forget all the countdown "help" onscreen. It only serve to rush the process for newbies. The jailbreak program will automatically detect when a device is in DFU mode at anytime in the count down.

So:

1. plug in usb AND power.

2. hold down menu and down at the same time until the led light on the front of the ATV blinks really, really rapidly. When that happens, you let go of both buttons and the ATV will reboot.

3. hold own menu and play/pause button until the led light blinks rapidly again. Once it does, you can let go of both buttons and your ATV will be in DFU state.

4. Launch GreenPois0n, answer yes to dialogue box that pops up, asking if you're gonna be jailbreaking the ATV. GeenPois0n will automatically detect that the device is already in DFU mode and you can begin the process by clicking the jailbreak button. IMPORTANT: After GreenPois0n shows complete, wait 1min before unplugging the USB cable. It allows all flash processes to complete unhindered.

5. Finally, unplug everything. Take your ATV to your TV, start plugging everything back in. Once it boots into Lowtide, go to the new GreenPois0n menu and inject the exploit. Make sure you have wifi set up or ethernet plugged in by this stage. That's all there is to it. You can install XBMC from the NitoTV menu that appears after the final reboot, or you can follow the wiki to ssh into your ATV to install it via commandline.

Seas0nPass is untethered. It is using the same jailbreak method than the latest greenp0ison. Please read the link I posted.
