The idea is to post MD5 sum or SHA1 so every one can check his ipsw before flashing.
How md5 are illegal is beyond my understanding..

Now back to the root.. Please post an md5 sum of working ipsw..

CASHMON3Y Wrote:Ive tried it on my ASUS netbook and my Minimac running Snow Leopard. Ive removed iTunes completely and reinstalled it on both systems. This is my second aTV, and my second microUSB cable when I know they are both fine. I dont really have any friends that would be willing to let me use their computer.

Can I run a VM machine and use Seasonpass to tether it back? I do understand that I need the AppleTV2,1_4.2.1_8C154_Custom_Restore.ipsw. Where is this stored so that I can get my friend to send it to me?

rflores2323 Wrote:ok well I just found this thread.

Need actual custom firmware, simply open it up and extract the following files (BTW, for those using Seas0nPass, the custom firmware created by the software can be found in your home directory):

dfu/iBSS.k66ap.RELEASE.dfu
kernelcache.release.k66

To open the .ipsw file in Windows, simply rename the .ipsw extension to .zip instead.

Then use the following Tethered Boot Utility for windows


With the tetheredboot tool and the two extracted files in the same folder, open up the command prompt and type in the following command:

tetheredboot -i iBSS.k66ap.RELEASE.dfu -k kernelcache.release.k66

Connect your ATV2 via USB to your computer and also plug in the power cable. Put it in DFU mode by holding down both the menu and play/pause button for 7secs. The tethered boot program should take over once it detects the ATV2. Let it complete, then remove the USB cable so you can plug in your HDMI cable.

I am going to try this tonight if I can get a hold of the IPSW files.

-Plug AppleTv into microUSB and your PC, also plug into AC power (no hdmi)
-Push the DOWN and MENU buttons on your apple remote until you see the white light flashing VERY rapidly (like 10 times per second)
-Within 1 second, push and hold the MENU and PLAY/PAUSE button on your AppleTV remote until the light flashes exactly like it did on the first press (10/second)

Your appleTv should now be in dfu mode. At this point, you should be able to run tetheredboot.exe and it shouldn't say "Device must be in DFU mode to continue". It should go ahead and do the tethered boot.

Once the boot is finished (2 different progress meters will go from 0-100%) immediately unplug your usb from the AppleTV and plug in your HDMI cable. That should do it!
