他有寫說Ipad 2 3G不適用此方法
It should be noted that this guide does not apply to 3G iPad 2 users running iOS 4.3.5. 必須要註明的是這個教學不適用於使用iOS4.3.5 的iPad 2 3G用戶
If you do have a 3G iPad 2 and have upgraded to iOS 4.3.5, then you are out of luck for now. 如果你有iPad2 3G而且已經升級到4.3.5,那只能說你現在很不幸

比較簡單的部分我抓重點翻譯
Step 1: Download the firmware file you want to downgrade to. As a matter of common sense, download the version which can be jailbroken untethered like iOS 4.3.3, but any of the versions we’re linking to below should work just fine.
步驟1.先下載你降檔之後想要的韌體版本,最好是用能夠完美JB的版本(例如4.3.3)
Step 2: In order to proceed, you’ll need to set your device into DFU mode, by taking the following steps:- Connect the device to your computer, turn it completely off, by holding the power button and sliding your finger along the red slider, just like you normally would, then launch iTunes.
- With your device still plugged in, press and hold both the power and home buttons for 10 seconds.
- After 10 seconds, release the power button but keep pressing the home button for 10 more seconds. At this point, your screen should be completely black. If you see the iTunes logo, you’re not in DFU mode. 此3個步驟是教你怎麼進入DFU模式,詳細教學請看吉米大的就可以了
步驟2.想要進行這個過程,必須要進入DFU模式
如果你無法成功進入DFU模式,跟著以上步驟再做一次而且確定你有照時間按應該要按的按鈕,可能需要經過多次反覆的練習
Step 3: once you have entered DFU mode, you need to trick iTunes into connecting to Saurik’s server instead of Apple’s servers. In order to do this, you’ll need to edit your hosts file, like we’re showing below.
If you’re on Windows: navigate to \Windows\System32\drivers\etc\ and locate the file named hosts. Back it up and open it in Notepad.
If you’re on Mac OS X: from Finder, hit the Go menu, select Go to Folder and type in /etc/. Now look for a file named hosts. Back it up and open it in TextEdit.
步驟3.進入DFU模式後,必須要使iTunes連結Saurik的伺服器而不是Apple的,想要做到這個就必須要修改hosts檔案,就像我們在下面秀出來的一樣(圖片請到原網頁去看)
如果是Windows系統:到\Windows\System32\drivers\etc\ 找到hosts這個檔案,備份好後用記事本開啟
如果是Mac OS X系統:(這我不敢亂翻,我沒用Mac,所以不知道一些正確的翻譯是啥,反正就跟Windows的比照辦理)
On either system, add the following line to the hosts file, then save it. Make sure you have administrative privileges:
74.208.105.171 gs.apple.com
不管是哪個系統,把下面這行(74.208.105.171 gs.apple.com)加到hosts檔案裡面,然後存檔,要確定你擁有管理者權限
Step 4: launch iTunes, select your device from the sidebar and click on Restore while holding Alt if you’re on the Mac and Shift if you’re on Windows. If everything goes as expected, you should be able to select the firmware file you’d like to downgrade to. Once you’ve done it, your device should be downgraded in a matter of minutes.
步驟4.開啟iTunes,從左邊選好你的裝置,之後 用Mac的按著Alt/用Windows的按著Shift 再按一下"回復",如果一路走來都如預期的,那應該會讓你選擇想要降檔的韌體,選好後你的裝置應該就會開始降檔了
Note: sometimes a 1013 error will pop up, throwing your device into recovery mode.
In order to return to standard mode, you simply need to download two utilities: TinyUmbrella (Windows, Mac) and Fix Recovery (Windows, Mac). Launch it and select Exit Recovery.
注意:有時候會出現1013錯誤,就把你的裝置進入恢復模式,要回到一般模式,只要下載2個軟體:TinyUmbrella and Fix Recovery (依照所使用的系統下載),打開然後選"Exit Recovery"(離開恢復模式)就好了
Once you’re done, your device should work normally. There’s one last step, however, if you’d like to receive future updates from Apple’s servers: restore the hosts file you’ve backed up earlier to its original location.
If you have downgraded to iOS 4.3.3, then simply follow our guide posted here on how to jailbreak (full untethered) iOS 4.3.3 using JailbreakMe 3.0.
一旦你完成了,你的裝置應該就會正常運作,不過還有最後一個步驟,就是如果未來你還想要收到從Apple伺服器提醒的更新,把hosts檔案回復到原本的樣子就可以了(就把備份好的丟回去取代)
如果成功降檔成iOS 4.3.3,那就可以照著我們的教學,看如何使用JailbreakMe 3.0來完美JB 4.3.3.
以上是那篇英文網站的翻譯,不過有人說他改了hosts檔案想要選擇韌體回復卻會出現3194錯誤,這我也不知怎麼回事...
有興趣、閒閒沒事做的朋友大家一起來測試這個方法吧XD
