Downgrading your 1.1.3 iPhone or iPod touch
If for whatever reason you've upgraded your unit to firmware version 1.1.3 and wish to return to an earlier installation, you can. You won't be able to use your iPhone, however, as a phone but only as a glorified iPod touch. Here, by popular request, is a quick how-to guide.
If you are getting Segmentation Fault errors, please read this
1. Get a fairly recent version of iPhuc There are many versions floating around. Make sure yours isn't too old.
2. Locate your 1.1.1 ipod software bundle. On the Mac, this is in ~/Library/iTunes/(iPhone or iPod) Software Updates.
3. Extract the ipsw file Create a new folder and unzip the 1.1.1 .ipsw file. It is actually a renamed zip archive.
4. Locate the WTF file Inside the unzipped ipsw folder go down to Firmware > dfu and find the file that starts with WTF.
5. Connect your iPod or iPhone to the computer and launch iPhuc Make sure that iPhuc connects to your unit and has a normal prompt (one where you can issue the "ls" command and see the contents of your Media folder). If iTunes starts up, quit it.
6. Enter recovery Type enterrecovery, press return and quit iPhuc. Your unit should go into recovery mode.
7. Relaunch iPhuc. You should now see the recovery mode options. Enter filecopytophone followed by the path to the WTF file and press return. Then Enter cmd go and press return. Quit iPhuc.
8. Launch iTunes. It will complain that it has found an iPod or iPhone in recovery mode. Click OK. Then Option-Click (Mac) or Shift-Click (Windows) the Restore button.
9. Choose the 1.1.1 ipsw file Locate the ipsw file (not the unzipped folder) and select it and start your restore. The screen *should* go white. That's normal. If all is well and good, your iPhone or iPod touch will downgrade succesfully.
10. Dealing with error 1015 If you run into error 1015, connect your newly restored unit to INdependence or try issuing a cmd fsboot from iPhuc.
Once downloaded, you'll have to go through all the standard re-activation and jailbreak procedures.

I get the fault 1604 when i try to restore it to 1.1.1... Any suggestions?

It is much simplier with an iPod Touch:
1. turn it off (red slider)
2. connect to USB and run iTunes
3. press both Sleep and Home buttons for 10 seconds
4. release Sleep and keep pressing Home for another 10 seconds then release
5. iTunes recognize iPod in restore mode but THIS TIME you can restore to 1.1.1 or 1.1.2 without "uknown error".

I've tried one 1.1.1 firmware and it gave me an unkown error and then I tried a different one and it did something and then dropped me back at the 1.1.3 springboard. Any suggestions?
Robin said 2:15PM on 1-26-2008
Before I tried what you (polo) wrote, I was getting unknown error 1, and it wouldn't even start the restore process.
Now, it hangs on "preparing ipod for restore" and then gives my unkown error 6104.
Any ideas?

Following Polo's method: How I restore iPod w/out choosing the "restore and upgrade" option, which automatically upgrades to 1.1.3?
Joes said 4:07PM on 1-16-2008
This will not erase the new apps from the ipod touch right?

HAs anyone tried to go to 1.02
SimplePanda said 4:13PM on 1-16-2008
Yes, it will erase the new apps from your Touch and it will be a plain, vanilla 1.1.1 or 1.1.2 installation.
Also, it MAY be possible to eventually downgrade the baseband on the iPhone and get a working phone again, but ONLY if the development community manages to get the secpack for the 1.1.3 baseband and ONLY if you have a bootloader 3.9 equipped phone.
The secpack is required to get the baseband flash to erase itself.
Previous to 1.1.3, extracting the secpack has been reasonably trivial. Unfortunately, with 1.1.3, according to the development community Apple has "done a really good job this time" with protecting the secpack and there is some doubt it will ever be extracted properly.

What about downgrading the baseband to get the phone functionality to work again? I've done it from 1.1.2 to 1.0.2, and was able to get the *Phone* part working (before downgrading the baseband, it would never get the activation signal from AT&T).
By downgrading the baseband, I mean something along the lines of this:

I will try this within the next day or so, but I can't imagine it wouldn't work...

I had the same problem but its because it is hard to read on the README doc. You have to put in : filecopytophone WTF.s518900xa11.RELEASE.dfu .... You put "l" instead of 1 hope this helps i still cant get my ipod downgraded :(

Erica, you mention that anyone who follows these instructions won't be able to use their iPhone as a phone, and at the bottom you say they can go through the standard activation procedure.
I'm confused. What do you mean?

Erica Sadun said 4:43PM on 1-16-2008
To activate you have to get past the "Connect to iTunes" screen. It wont' mean you'll have a working phone that makes call.
