ふみぃ~.何だか虚しい・・・
たぶんしないと思いますが自分用メモです.
試してみようと思われる方は,バックアップ(特に“iPod touch App Pack 4A93.ipa”)を行ったうえ自己責任で.

1. Get a fairly recent version of iPhuc. There are many versions floating around. Make sure yours isn't too old. (Link)

2. Locate your 1.1.1 ipod software bundle. On the Mac, this is in ~/Library/iTunes/(iPhone or iPod) Software Updates. (iPhone, iPod touch)

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.


コメントにあった方法(iPod touch限定?).

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".

Windows用?
もよこさん,情報どうもありがとうございます.

動画はここに貼ってるやつと同じもので,リンク先のソフトはWindows用のバイナリなのでしょうか?
方法自体は同じみたいですね.
