AppleTV 2.1 Safe Update

<Google>WIKI</Google>

Warning

Safe Update is recommended against by Nito! Read this for more info.

Overview

I am just creating a basic stripped down page on how to perform a safe update procedure with the new Take 2 update released on 02-12-08.

NOTE: Not all of the plugins work on take 2 yet, there are a few in beta and only Couch Surfer is full.

==> NOTE: The 1080i resolution seems to be missing after doing the safe update. Perhaps there is a required change in the HDMI firmware update?

To shed some light about the HDMI firmware update question, here's a quote from an AppleInsider.com review:

The 2.0/2.1 updates include four software upgrades:

   * An EFI firmware update.
   * An IR firmware update. (2.1 only)
   * A firmware update for the Apple TV's HDMI video hardware that enables 1080p output through upconversion and HDCP copy protection.
   * Updated Mac OS X software with support for HD downloads, rentals, AirTunes and more.

The safe update procedure is basically identical to the last one, with one extra framework to add and one extra framework to swap in.

Procedure

Download the dmg for AppleTV 2.1

Copy this over to your frontrow folder through ssh or a mounted remote drive

scp -1 2Z694-5485-1.dmg frontrow@AppleTV.local:~/

frontrow as password

ssh -1 frontrow@AppleTV.local

frontrow as password

cd ~
hdiutil mount 2Z694-5485-1.dmg
  

after the image is mounted we are going to go to the PrivateFrameworks, CoreServices and Frameworks folder and make backups of all the current important files to revert to 1.1 if desired.

sudo mount -o remount,rw /dev/disk0s3 /
cd /System/Library/PrivateFrameworks/
sudo mv BackRow.framework BackRow.framework.20
sudo mv AppleTV.framework AppleTV.framework.20
sudo mv iPhotoAccess.framework iPhotoAccess.framework.20

cd /System/Library/CoreServices/
sudo mv Finder.app Finder20.app

cd /System/Library/Frameworks/
sudo mv QuartzCore.framework QuartzCore.framework.20
sudo mv CoreVideo.framework CoreVideo.framework.20

okay now everything for 2.0 is backed up now to move in the new Finder and frameworks

Private frameworks (same as last safe update)

sudo cp -r /Volumes/OSBoot\ 1/System/Library/PrivateFrameworks/AppleTV.framework /System/Library/PrivateFrameworks/AppleTV.framework
sudo cp -r /Volumes/OSBoot\ 1/System/Library/PrivateFrameworks/BackRow.framework /System/Library/PrivateFrameworks/BackRow.framework
sudo cp -r /Volumes/OSBoot\ 1/System/Library/PrivateFrameworks/iPhotoAccess.framework /System/Library/PrivateFrameworks/iPhotoAccess.framework

Frameworks (new for take 2)

sudo cp -r /Volumes/OSBoot\ 1/System/Library/Frameworks/QuartzCore.framework /System/Library/Frameworks/QuartzCore.framework

sudo cp -r /Volumes/OSBoot\ 1/System/Library/Frameworks/CoreVideo.framework /System/Library/Frameworks/CoreVideo.framework

Finder

sudo cp -r /Volumes/OSBoot\ 1/System/Library/CoreServices/Finder.app /System/Library/CoreServices/Finder.app

Fixing helper permissions

sudo chmod u+s /System/Library/PrivateFrameworks/AppleTV.framework/Resources/SettingsHelper

now just kill the finder and the new one should load up

kill `ps awwx | grep [F]inder | awk '{print $1}'`

Airtunes

sudo cp -r /Volumes/OSBoot\ 1/usr/libexec/airtunesd /usr/libexec/airtunesd
sudo cp -r /Volumes/OSBoot\ 1/System/Library/LaunchAgents/com.apple.airtunesd.plist /System/Library/LaunchAgents/com.apple.airtunesd.plist

You need to copy the new "mach_kernel.prelink" from the 2.1 update file as well as follows:

cd /
sudo mv mach_kernel.prelink mach_kernel.prelink.old
sudo cp /Volumes/OSBoot\ 1/mach_kernel.prelink /mach_kernel.prelink
sudo chown root:wheel /mach_kernel.prelink

Reboot your AppleTV and AirTunes should be working for you.

Afterword

This is hot off the presses so I know the Finder, Airtunes and iPhone remote appears to work okay, report any problems here on the wiki, on the forum or in the chatroom.
