These are instructions on how to update your 1.1.2 Jailbroken iPhone to the 1.1.3 iPhone firmware using Mac. You can find windows instructions here: http://www.iclarified.com/entry/index.php?enid=604

I would like to note that Nate True has released this jailbreak by going rogue from the Dev Team. He is no longer a part of that team. This release is not supported by the Dev Team either. It might be a good idea to wait for the official release; however, for those who can't wait I have posted this tutorial. It clearly did work for me, though success seems to be varied. Its too bad that it happened this way.

What you need:
- Download the 1.1.3 Package Maker from: here

Step One
You must have a 1.1.1 or 1.1.2 jailbroken phone with Installer.app installed. If you need to know how to do this you can follow one of these tutorials:

Windows: http://www.iclarified.com/entry/index.php?enid=461
Mac: http://www.iclarified.com/entry/index.php?enid=455

Step Two
Connect your iPhone to the computer

Step Three
Mount the 1.1.3 Package Maker by double clicking the file(jb113.dmg) we downloaded earlier.

Step Four
From the mounted jb113 dmg double click the Run_This program.


Step Five
The program will run in Terminal. Make sure your iPhone is plugged in and press Enter.


Step Six
The program will check if your iPhone qualifies for the Soft Update. If it does you will be prompted to press Enter to search for the 1.1.3 Firmware.


Step Seven
If the firmware is not found then press Enter again to download it!


Step Eight
Once it has downloaded the firmware it will also download the patch. The program is now ready to upload the necessary files to your iPhone. Press the Enter key to continue.


Step Nine
It will take about 5 minutes to upload the files to your iPhone. When done you will be prompted to install the 1.1.3 soft upgrade package from Installer.


Step Ten
Press to launch Installer from the Springboard.


Step Eleven
If you get prompted for an Installer Update click the Update Now button.


Step Twelve
If Installer was updated click the Ok button.


Step Thirteen
Press to launch Installer from your Springboard again. (If you had to update).


Step Fourteen
If asked to Donate click the Donate Later button for now.


Step Fifteen
Press to select the Install tab at the bottom of the screen.


Step Sixteen
Press to select System from the list of Categories.


Step Seventeen
Press to select 1.1.3 soft upgrade from the list of Packages.


Step Eighteen
Press the Install button at the top right of the screen.


Step Nineteen
Press the large Install button that appears.


Your iPhone will install the Soft Update package then reboot. This takes a few minutes.

At this point I got an execution error and my iPhone screen went garbled. I noticed there was an OK button and I pressed it. The loading animation kept turning on the screen for a few minutes until I gave up and held down the Sleep/Wake button and Home button at the same time. The phone then powered down. I pressed the Sleep/Wake button again and turned the iPhone back on.

I got a "Edit Home Screen" message once the phone booted. Click the Dismiss button and you will have SUCCESS!!!!

CLEANUP: You should delete the file that iBrickr copies over to your iPhone its 300+ Mb. I'll add instructions as soon as things get less hectic. For now the file is at: ./var/root/media/softupdate

NOTES*: I noticed that SSH is not working... To fix it I had to reinstall BSD Subsystem from Installer. Then I installed OpenSSH from Installer.

THANKS: Since I don't know everyone on the Dev Teams I am gonna borrow netkas' thank you. Props to everyone on the Dev Team, including (in no particular order): netkas, NerveGas, asap18, bgm, Bugout, bushing, chris_, dinopio, drudge, Fred_, gray, MuscleNerd, natetrue, pr3d4t0r, roxfan, Turbo, Zfstrike, np101137, pumpkin, dubeditions(PhilMugPH) and kroo, along with many contributors who wish to remain anonymous. And props to planetbeing, who was the first person with a 1.1.3 jailbroken iphone, and Zibri, by whom this method was largely developed. Additionally to Shaun Erickson, who packaged the Installer half of the upgrade, and runs most of the application packaging for the iPhone.
