ios beta 下載

So you’ve?installed the iOS 11 beta?and, well, you don’t love it. No problem, because you can?roll right back to iOS 10.

因此，您已經安裝了iOS 11 Beta ，但是，您不喜歡它。 沒問題，因為您可以直接回滾到iOS 10。

However, note that this will wipe your device completely, which could pose a problem.?Let’s say you didn’t follow our advice to do a full backup before leaping into iOS 11 beta. In that case, if you downgrade to iOS 10, you’re looking at a full device wipe and any data you don’t have backed up in another way (like photos copied to your computer outside of iTunes?or iCloud), will be erased.

但是，請注意，這將徹底擦除您的設備，這可能會引起問題。 假設您在進入iOS 11測試版之前沒有遵循我們的建議進行完整備份。 在這種情況下，如果您降級到iOS 10，則表示正在擦除整個設備，并且您沒有以其他方式備份的所有數據(例如，將照片復制到iTunes或iCloud之外的計算機上)都將被刪除。 。

In addition, regardless of whether or not you backed up the device when it was on iOS 10, any changes made or data created on your phone between the iOS 11 beta update and the rollback will be lost.

此外，無論您是否在iOS 10上備份設備時，在iOS 11 Beta更新和回滾之間在手機上所做的任何更改或創建的數據都將丟失。

If you were just playing around with iOS 11 beta on a spare device, that’s not such a big deal. If you somehow found yourself in the unenviable position of installing iOS 11 beta on your primary device?and?you didn’t back it up first, however, you might want to consider just chugging along with iOS 11 to save yourself the lost data.

如果您只是在備用設備上玩iOS 11 beta，那就沒什么大不了的了。 如果您以某種方式發現自己無法在主要設備上安裝iOS 11 beta，并且您沒有首先備份它，那么您可能要考慮與iOS 11兼容，以保存丟失的數據。

Lastly, this tutorial will only help you downgrade from the iOS 11?beta?to iOS 10.3.3, and it will only work up until the public release of iOS 11. After that, Apple will stop signing older iOS firmware versions?and you will not be able to?downgrade to them.

最后，本教程將僅幫助您從iOS 11 beta降級到iOS 10.3.3，并且僅在iOS 11公開發布之前才能運行。此后，Apple將停止對較早的iOS固件版本進行簽名，并且您不會能夠降級到他們。

Those cautions?aside, let’s jump right into the pretty easy rollback process.

除了這些警告，讓我們直接進入非常簡單的回滾過程。

你需要什么 (What You Need)

To follow along today, you need just a few things. You’ll need your device, a USB data cable for said device, an up-to-date copy of iTunes, and you’ll need to download the appropriate iPSW file for your device. For the unfamiliar, iPSW files are the firmware files for iOS devices. Using an iPSW file to reset or restore your device is like performing a complete factory reset.

要跟隨今天，您只需要注意幾件事。 您將需要您的設備，用于該設備的USB數據線，iTunes的最新副本，并且需要為該設備下載適當的iPSW文件。 對于不熟悉的人，iPSW文件是iOS設備的固件文件。 使用iPSW文件重置或還原設備就像執行完整的出廠重置一樣。

All of the files listed below, organized by device model, are hosted directly by Apple. We’ve merely organized the direct links for ease of use. When you’re ready to roll back,?download the matching iPSW file for your device. Unsure exactly which file you should download for your device? Check the model number on the case and use?this iOS device list?to confirm which device you have.

下面列出的所有文件(按設備型號組織)直接由Apple托管。 我們只是組織了直接鏈接以便于使用。 準備回滾時，為您的設備下載匹配的iPSW文件。 不確定要為設備下載哪個文件？ 檢查機殼上的型號，然后使用此iOS設備列表確認您擁有的設備。

如何將設備回滾到iOS 10 (How to Roll Your Device Back to iOS 10)

First,?if you’ve enabled?the “Find My iPhone” feature?for your iPhone or iPad, you will need to turn that feature off first. You must do this from the iPhone or iPad itself.?Head to Settings > [Your Name] > iCloud > Find My iPhone or Find My iPad and ensure the feature is turned off.

首先，如果您為iPhone或iPad啟用了“查找我的iPhone”功能，則需要先關閉該功能。 您必須從iPhone或iPad本身執行此操作。 轉到設置> [您的名字]> iCloud>查找我的iPhone或查找我的iPad，并確保該功能已關閉。

With the iPSW file in hand, plug your iOS device into your PC or Mac with the USB cable and fire up iTunes. Inside iTunes, click on the device icon (located in the upper left corner and highlighted in the screenshot below).

手持iPSW文件后，使用USB電纜將iOS設備插入PC或Mac，然后啟動iTunes。 在iTunes中，單擊設備圖標(位于左上角，并在下面的屏幕快照中突出顯示)。

Within the device’s “Summary” page (the default view), locate the “Restore [Device Name]…” button in the Summary panel. Press?and hold the Option?key (Mac) or Shift key (Windows) and click the button. You?must?press the keyboard key while clicking the button in order to load the file browser?to select a custom restore file. If you don’t, iTunes will only allow you to select from local backups you’ve made.

在設備的“摘要”頁面(默認視圖)內，在“摘要”面板中找到“還原[設備名稱]…”按鈕。 按住Option鍵(Mac)或Shift鍵(Windows)，然后單擊按鈕。 您必須在單擊按鈕的同時按下鍵盤鍵，才能加載文件瀏覽器以選擇自定義還原文件。 如果您不這樣做，iTunes將僅允許您從制作的本地備份中進行選擇。

When you click the Restore button, you?won’t?be prompted to back up your device, get any data off it, or warned in any fashion. The presumption is that, because you know this?super secret key combination, you know what you’re doing.

單擊“還原”按鈕時，不會提示您備份設備，獲取任何數據或以任何方式發出警告。 假設是，因為您知道此超級密鑰組合，所以您知道自己在做什么。

In the file browser?that pops up, navigate to the iPSW file for your device in the location you saved the download. Select it (make sure, if you have multiple devices, you select the correct one for the device you’re currently wiping and restoring) and then click?“Open” to start the process.

在彈出的文件瀏覽器中，在保存下載的位置導航到設備的iPSW文件。 選擇它(確保，如果您有多個設備，請為當前要擦除和還原的設備選擇正確的設備)，然后單擊“打開”以開始該過程。

Click “Restore” to continue and erase the contents of your iPhone or iPad.

單擊“還原”以繼續并擦除iPhone或iPad的內容。

If you see an error message instead, you probably downloaded the wrong iPSW file for your device.

如果看到錯誤消息，則可能是設備下載了錯誤的iPSW文件。

Once you click “Restore”, it’s go time: your iOS device will be wiped and the iOS software will be downgraded from iOS 11 Beta to iOS 10.3.3. When the process is finished, your device will boot back up as if you’d just turned it on for the first time, welcome screen and all. At that point you can either start with a totally fresh copy of iOS 10?or you can copy your old iOS 10?backup (if you made one) from iTunes or iCloud.

單擊“還原”后，就該開始了：您的iOS設備將被擦除，iOS軟件將從iOS 11 Beta降級到iOS 10.3.3。 該過程完成后，設備將重新啟動，就像您是第一次打開設備時一樣，歡迎屏幕等等。 屆時，您可以從全新的iOS 10副本開始，也可以從iTunes或iCloud復制舊的iOS 10備份(如果已創建)。

If you made a backup in iTunes, iTunes will ask you if you want to restore that backup to your device right after it finishes installing iOS 10. Select the backup and click “Continue” to do so.

如果您在iTunes中進行了備份，iTunes將在完成安裝iOS 10后詢問您是否要將備份還原到設備上。選擇備份，然后單擊“繼續”。

At this point, be it with a fresh install or your old iOS 10 backup restored, you’re back on iOS 10 and can linger there as long as you want. However, you’ll probably want to upgrade to iOS 11 when the final, stable version is released later in 2017.

此時，無論是全新安裝還是還原了舊的iOS 10備份，您都可以使用iOS 10，并且可以在任何地方徘徊。 但是，您可能要在2017年晚些時候發布最終的穩定版本時升級到iOS 11。
