How to: Downgrade from 1.1.3 to 1.1.1

This write up is obsolete. It still applies if you want to downgrade 1.1.3 (and future versions) into 1.1.1. Since there's a title limitation, this applies to any form of downgrade, but more specifically downgrading from 1.1.3.

For the sake of completeness, I'm going to re-post whatever I might have posted in my other posts earlier.

NOTE: This tutorial is mainly written for Windows user and only users using iPod Touch. If you're using iPhone, please look elsewhere. I cannot guarantee that this method would work on an iPhone simply because 1) I do not own one and 2) there's no iPhone sale here in Singapore.

This method does not involve in using iphuc or any hack files like the one descibed by ipodtouchmaster. If you do not have any success doing this, you may want to try the iphuc method.

I'm not a Mac user hence I'm not sure of the keyboard layouts, mouse clicks etc, but if you understand, the methods are almost the same.

IMPORTANT NOTICE:

If you're attempting to downgrade your 1.1.3 firmware using this guide, please take note that all your data will be wiped out. Your songs, pictures, videos, everything. If you have made purchased music through iTunes, that will also get wiped out. Do this only if you have means of putting your media back onto your player without any problems.

DFU Mode

Read this post for all methods of getting into DFU mode.


Downgrade to firmware 1.1.1

So now you want to downgrade it back to 1.1.1? Download the 1.1.1 firmware file first. Make sure the file ends with a _Restore.ipsw for the sake of this tutorial. Please put the file somewhere accessible where you can remember it (like the desktop). If you download this, make sure you keep it safe in your computer, it might come in handy for future updates to the firmware.

IMPORTANT NOTE

It seems that people keep hitting error (1403) while trying to downgrade to 1.1.1. It simply means that you did not download the firmware completely, hence making it a "broken file".

To confirm your file, check it's file size.

The size for firmware 1.1.1 restore is:
- 150 MB
- 157,906,686 bytes

If you get any other figures, you probably got the wrong version, or a broken download. Try downloading it again. If it still gets another figure, try clearing your cache, then download it again.

So while your iPod Touch is in DFU mode (please do that if you haven't done so), you'll need to perform a manual upgrade on the iPod Touch.

Step 1: Go to where you normally see your firmware version.

Step 2: Now hold Shift key while left clicking on Restore. A file browser should come up, so select the 1.1.1 firmware from the list (navigate to where you saved the downloaded file).

Now all you have to do is wait until your iPod finishes. It might take a while so go make a coffee (one for me too please!) and maybe watch a few TV programmes.


Jailbreak the now version 1.1.1

Yey! If you managed to get it done, you can now jailbreak it. Follow my post here on detailed steps on how you can do that. I'm sure you should already know what to do right?

You're now good to go! Cheers!
