Apple TV Jailbreak iOS5.1 untethered (5.1.1 update)

This is what we have been waiting for... and untethered jailbreak for iOS5.1

Firecore just released the untethered version of their jailbreak. so far i've been using the tethered jailbreak provided by firecore. i'm a little concerned that the new jailbreak will break my setup again since many people have complained that they can not install xbmc on it.


-- Update --
now that there is another untethered update i ventured and tried to update my atv2 to untethered jailbreak. since because of blackouts and stuff, i need to keep booting it up with my laptop.

i updated to the new season pass tool for my mac and then run it to generete the ipsw file. it did with no problem. but the season pass tool script to upload via itunes failed to execute properly. i read that the script does not work well with Mountain Lion. Since i know that season pass created the ipsw file in the same location as before. i just opened itunes and put the atv in dfu mode. next itunes recognized the "device in dfu mode" and presents the restore screen for the apple tv. so i just pressed the option key and clicked on the restore button. this opens finder so you can browse for the ipsw file. once you select the ipsw file you want to update then it just went on and try to restore the firmware.

some problems that i run into while doing the firmware update were the infamous errors 1602,1604 for 1602 i remembered that it had something to do with the apple server for firmware validation... so to solve that problem you have to check that the /etc/hosts file does not have the cidia ip address for the gs.apple.com dns. In my case it was put there by tiny umbrella application that i used to update the firmware earlier. once i removed the entry on the hosts file. the firmware update seemed to proceed, except that i got the 1604 error which seemed a little more odd since according to apple website means that there is a timing issue with the usb cable, so they just tell you to try a different port or a different cable. since i know that my cable is ok since i used it to flash the firmware before, then i was a little frustrated. but once method you can use to test your cable is to just let itunes restore the official firmware to the atv. that way if its successful, it means that your cable is good.

another reason to let it update the official firmware is to let the atv be in a 'good' state so when you go to flash it with the hacked firmware you just created with season pass then it should work correctly.

and i think that is what happened in my case, after like 10 different times trying to flash the season pass image, i flashed the official ipsw, then the next time i flashed the season pass ipsw it passes the point of failure.

after all this pain and suffering, you should back up your ipsw, your apple tv shsh file (tiny umbrella) and the xbmc catalog.

so until next time, its all couch surfing ....

setting up a bridge for your network

to bridge the gap between network devices that are not wireless n or to extend your network to other rooms or around the house without running ethernet cables around the house.... you can create a wireless bridge with a spare wireless n router and dd-wrt firmware. in my case I've accumulated some routers that i can use as wireless bridge. the first thing to do is to check if your wireless router is supported by looking it up in the dd-wrt database. Then follow the instructions to flash your routers and set them as wireless bridges. it is easy to do, but it requires to follow some technical instructions and sometimes patience since the instructions may be confusing.

this is my setup:

The main router is a Cisco-Linksys E3000 Wireless-N Router. since i flashed most of my routers to dd-wrt i decided to stick with it for the main router aswell, for consistency. It is capable of wireless n at 5 ghz and n,g at 2.4 ghz plus gigabit ethernet. Connected to it are a D-Link DNS-321 2-Bay Network Attached Storage at gigabit ethernet,  Apple TV MC572LL/A (2010) [OLD VERSION] at wireless n 5ghz,  a PC at wireless g 2.4 ghz, another PC at wireless n 5 ghz, a tablet wireless n 5 ghz and finally two wireless bridges. Bridge one is a Cisco-Linksys E2000 Advanced Wireless-N Router with dd-wrt (capable of wireless n at 5 ghz or 2.4 ghz) currently using 5 ghz. Connected to the bridge via ethernet are an Xbox 360 4GB Console and a playstation 2.  The second bridge is a Cisco-Linksys WRT54G2 Wireless-G Broadband Router with dd-wrt (capable of wireless g at 2.4 ghz). Connected to this bridge via ethernet is a network printer.

Bridge three is currently in the works. Its an ASUS WL-520GU Wireless Router (capable of wireless g at 2.4 ghz) and i'm planning to connect a USB Camera to it. this router i've flashed with Open-wrt firmware and is currently a wifi radio.

Apple tv jailbreak IOS 5.1

It happened again, Apple TV crashed and in a desperate move to restore it, the newest iOS got installed.  I was dreading my rush actions, so for a couple of weeks i kept postponing fixing the ATV... Lazyness, and also due to incompatibilities with the new iOS.
I really missed my awesome setup. So I decided to give it another shot and jailbreak the now Apple TV with iOS 5.1.

I started with searching on firecore.com website for the new season pass jailbreak tool, since I read the new iOS jailbreak had been released. After I searched for instructions on the procedure, I realized the new jailbreak is a tethered boot, which means that every time the ATV is cold boot started, it needs a computer to be attached by USB cable to boot up. The firecore.com website offers all the instructions necessary and the tool also can be used for the tethered boot after the jailbreak.

So the process went something like this...
I started the season pass jailbreak tool and clicked on create ispw button.
I waited for the tool to finish creating the jailbreaked image.
Then the tool asked to attach the ATV via micro USB cable.
After that the tool waits for the ATV to be in DFU mode, which you can accomplish by pointing the remote to the Apple TV and pressing the MENU and PLAY keys and holding them for 7 seconds. When the tool detects the ATV it loads a special boot loader.
Then the tool launches iTunes to load the image.
iTunes goes ahead and uncompressed the image and verifies the image with the Apple website.
Once the image is verified iTunes loads the image into the ATV.
After the load is complete the ATV is restarted.

Note: I did have problems and  was getting 1600, 1604, etc error in iTunes, when loading the image, but it was because, i forgot that i have used tiny umbrella before and the hosts file of my machine was changed to point the gs.apple.com to the cydia website. and i was getting the error because of that. The solution was to comment out the entries tiny umbrella had made. and re download the ipsw image.

Now is time for the tethered boot.
I Pressed the tethered boot button on the tool and attach the power cable.
In order for the tool to detect the ATV, the MENU and PLAY buttons must be pressed again for 7 seconds.
This time the tool boots up the Apple TV with the new image.
You can double check the jailbreak by inspecting the settings button, which shape the firecore logo.
And that's it, the ATV is jail broken.

Next to install xbmc i checked the xbmc forum for the instructions.
I opened a secure shell to the apple tv and issued some command to install the xbmc app. These are the commands i used on the terminal.
ssh root@{apple tv address} <enter>
password <enter>

then entered each of these lines.
apt-get update
mkdir -p /Applications/AppleTV.app/Appliances
apt-get install org.xbmc.xbmc-atv2
