Since all of the other guides for Windows that are currently out don't seem to work (because iRecovery and rslite differ in the way they send files), here's one that should work. I also believe that it is very complete. If you have any suggestions, I'll edit them in. What you'll need: redsn0w lite XPwn iRecovery and libusb 2.1.1 IPSW 2.2.1 IPSW Optional: Installer.app bundle for XPwn XPwn does not include Installer by default, but if you want to build a custom IPSW that includes Installer.app, save this package to your XPwn-0.5.7-win32\bundles\ folder. Do not extract the .tar, leave it as is! 64-bit users: There is currently no way to jailbreak using a 64-bit version of Windows. However, progress has been made and I will edit in the steps you need to take to get libusb working when they become available. All users: If you experience weird errors while running iRecovery (side-by-side configuration errors, etc.), install this. Important but obvious note: Backup your iPod using iTunes (right click on it's name, then select backup); you'll be able to recover all of your data after jailbreaking by selecting to restore form this backup. 1.) Extract redsn0w lite and XPwn to your Desktop. 2.) Save (or move) the 2.2.1 IPSW into the XPwn folder. 3.) Copy the rslite\FirmwareBundles\iPod2,1_2.2.1_5H11.bundle folder into your XPwn-0.5.7-win32\FirmwareBundles\ folder. Copy the whole folder, not just the included files. 4.) Open up a Command Prompt (type cmd in the Search bar if on Vista). 5.) Type the following: Code: cd C:\Users\yourusername\Desktop\XPwn-0.5.7-win32\ ipsw "iPod2,1_2.2.1_5H11a_Restore.ipsw" "iPod2,1_2.2.1_5H11a_Custom_Restore.ipsw" -s 700 bundles\Cydia.tar If you wish to include Installer.app, your syntax will be different. Please be sure you have the Installer tarball in your bundles folder; if you do not have this, it is explained above. However, your syntax would be: Code: cd C:\Users\yourusername\Desktop\XPwn-0.5.7-win32\ ipsw "iPod2,1_2.2.1_5H11a_Restore.ipsw" "iPod2,1_2.2.1_5H11a_Custom_Restore.ipsw" -s 700 bundles\Cydia.tar bundles\Installer.tar If you're running XP, your location will be a bit different (should be C:\Documents and Settings\yourusername\Desktop\). Also, if you're running XP (with PowerToys), Vista, or 7, you can easily navigate to folders in a Command Prompt without using cd. Simply hold shift, then right click on a folder (here, for example, you'd shift and right click on XPwn-0.5.7-win32), then select Open Command Window here. This can be done with any other part of this tutorial that involves cd. Thanks, MatthewH12! 6.) Wait for XPwn to finish, it should only take a few minutes. 7.) Extract all files in the iRecovery RAR to your Desktop and open the iRecovery folder, there should be an installer for libusb located here. If you haven't already installed libusb, please do so now. If you're running Vista or 7, please right click the .exe and select Properties, then click the Compatibility tab, then select Windows XP (Service Pack 2) from the drop-down menu. After install, a restart may be required. 8.) Open another Command Prompt (or use the one you used before, if it is still up) and type the following: Code: cd C:\Users\yourusername\Desktop\iRecovery\iRecovery_SVN Again, your location will be different if you're on XP, see above. 9.) Extract your 2.1.1 iBSS and 2.2.1 iBSS and iBoot. To do so, right click your 2.1.1 IPSW and select Open with > WinRAR archiver. Navigate to the Firmware\dfu directory, then drag iBSS.n72ap.RELEASE.dfu into your iRecovery_SVN folder. Rename it iBSS211.dfu. Now, open up your custom 2.2.1 IPSW using WinRAR. First, navigate to the Firmware\dfu folder and drag iBSS.n72ap.RELEASE.dfu into your iRecovery_SVN folder. Rename is iBSS221.dfu. Now, navigate to the Firmware\all_flash\all_flash.n72ap.production folder. Extract iBoot.n72ap.RELEASE.img3 to your iRecovery_SVN folder. Rename it iBoot221.img3. 10.) Put your iPod into DFU mode. If you're unfamiliar with DFU mode, you can put your iPod into it by holding the power button, then sliding to power off. Hold both the home and power buttons for 10 seconds (count in your head, it should be fine if you're off by a few seconds). After 10 seconds, release the power button and continue holding the home button for 15-25 seconds. Your screen shouldn't turn on, but your device should be recognized by iTunes as being in recovery mode. If at any point Windows claims that the device is unrecognized, be very exact with your timing and you should be able to enter DFU mode. Bring up your Command Prompt again and execute the following: Code: iRecovery -f iBSS211.dfu Your iPod's screen should turn white. If it doesn't, unplug your iPod and wait 10 seconds, then plug it back in. 11.) In the same Command Prompt, enter the following: Code: iRecovery -s arm7_stop mw 0x9000000 0xe59f3014 mw 0x9000004 0xe3a02a02 mw 0x9000008 0xe1c320b0 mw 0x900000c 0xe3e02000 mw 0x9000010 0xe2833c9d mw 0x9000014 0xe58326c0 mw 0x9000018 0xeafffffe mw 0x900001c 0x2200f300 arm7_go arm7_stop /exit Just to clarify, you will hit enter after each of these commands. 12.) Restore to your custom firmware using iTunes (hold shift and hit Restore, then select iPod2,1_2.2.1_5H11_Custom_Restore.ipsw). It may hang on "Preparing.." for a long time; just wait it out, it'll move on eventually. 13.) After your restore is complete, put you iPod into DFU mode. It may seem like your iPod is "bricked" (Windows says the device is unrecognized), but don't panic. Simply be very exact with your DFU timing and iTunes should recognize your device (it'll tell you it needs to be restored, don't do that though). Enter the following in your Command Prompt: Code: iRecovery -f iBSS211.dfu Unplug your iPod, wait 10 seconds, then plug it back in. Your screen should be white now. Run the following after: Code: iRecovery -s arm7_stop mw 0x9000000 0xe59f3014 mw 0x9000004 0xe3a02a02 mw 0x9000008 0xe1c320b0 mw 0x900000c 0xe3e02000 mw 0x9000010 0xe2833c9d mw 0x9000014 0xe58326c0 mw 0x9000018 0xeafffffe mw 0x900001c 0x2200f300 arm7_go arm7_stop /sendfile iBSS221.dfu go /exit Wait for your iPod to reconnect (it should disappear in iTunes, then reappear in a couple seconds). Run the following: Code: iRecovery -f iBoot221.img3 iRecovery -s go /exit 14.) Your iPod should now be booting; enjoy you tethered jailbreak. Also, don't forget that if you want to reboot your iPod, each time you'll have to repeat step 13 and step 13 only. Disclaimer: By following these instructions, you take responsibility for whatever may happen to your iPod. It is not that dangerous, but it's not my fault if something weird were to happen. Note: Don't PM me, I won't respond in most cases. Please ask in the thread, since there is most likely a solution to your problem.
