通常，只需简单的重启即可解决 iPhone 上的奇怪问题。但很少，您会遇到需要您强制重启并进入 iPhone 恢复模式的严重问题。
例如，您的 iPhone 可能会在启动时卡住、进入连续的引导循环(engages in a continuous boot loop)或对触摸无响应。强制重启可帮助您重新启动无响应的设备，但采取额外步骤并进入恢复模式也可以让您有机会永久解决问题。
iPhone 恢复模式为您提供了两种选择。您可以使用最新版本的 iOS 更新您的 iPhone，同时保持您的数据完好无损。或者，您可以选择将其重置为出厂设置。如果您有本地或 iCloud 备份，您还可以恢复您的数据，以防设备再次开始正常运行。
也就是说，强制重启 iPhone，更不用说进入恢复模式，可能会有点令人困惑，因为不同 iPhone 型号的过程不同。iPad 也是如此。您必须事先做好一些基本的准备工作。
如何为 iPhone 或 iPad 恢复模式做准备(How To Prepare for iPhone or iPad Recovery Mode)
要强制重启 iPhone 或 iPad 并进入恢复模式，您必须拥有Mac或 PC。最好使用具有iPhone 或 iPad 本地备份的(local backup of your iPhone or iPad)设备，因为您最终可能会重置设备。否则，任何Mac或 PC 都可以，因为恢复模式不需要您“信任”桌面。
在 macOS Catalina和更新版本中，一旦 iPhone 或 iPad 处于恢复模式，您必须使用Finder应用程序与它进行交互。在 macOS Mojave和更早版本以及Windows上，您必须使用 iTunes。如果您使用的是 PC 并且没有 iTunes，请在继续之前安装它。(install it)
也就是说，首先通过USB将您的 iPhone 或 iPad 连接到(USB)Mac或 PC 。您可能必须在只有USB -C 端口的Mac上使用(Mac)USB -C 转USB 适配器。(USB Adapter)然后，打开Finder或 iTunes。您现在已准备好进入恢复模式(Recovery Mode)。
如何强制重启 iPhone 并进入恢复模式(How To Force Restart an iPhone and Enter Recovery Mode)
根据您的 iPhone 型号，您必须使用三种不同方法中的一种来强制重启并进入恢复模式。
iPhone 8 系列、iPhone X 及更新机型(iPhone 8 Series, iPhone X, and Later)
在 iPhone 8 系列及后续机型上，包括所有具有Face ID功能的 iPhone（例如 iPhone X）以及基于Touch ID 的 iPhone SE（2020），您必须使用三个按钮的组合来强制重启并进入恢复模式。按以下顺序按下它们：

屏幕应该变黑，Apple标志应该很快就会出现。继续(Continue)按住，直到您看到恢复模式屏幕。然后您可以松开这两个按钮。
如何强制重启 iPad 并进入恢复模式(How To Force Restart an iPad and Enter Recovery Mode)
如果您想强制重启 iPad 并进入恢复模式，您必须根据您的设备是否有主(Home)屏幕按钮，采用两种方法之一。
没有 Home 键的 iPad(iPads Without a Home Button)
在没有Home按钮的 iPad 上，例如 iPad Pro (2018) 及更新版本，按正确顺序按下以下按钮以强制重启并进入恢复模式：
1. 按下并快速松开音量调高(Volume Up)按钮。
2. 按下并快速松开降低音量(Volume Down)按钮。
3. 按住顶部(Top)（睡眠/唤醒）按钮。

按住两个按钮，直到屏幕上出现恢复模式屏幕。然后您可以松开这两个按钮。
如何使用恢复模式(How To Use Recovery Mode)
在 iPhone 或 iPad 上进入恢复模式后，您将在Finder(Finder)或 iTunes 中自动看到一个弹出通知，提示您更新或恢复设备。
我们建议您先更新您的 iPhone 或 iPad。选择更新(Update)，您的Mac或 PC 将尝试下载并安装最新版本的 iOS 或 iPadOS，而不会删除您的数据。
如果您的设备退出恢复模式并自动重启（在 15 分钟后发生），请等待下载完成，重新进入恢复模式，然后再次选择更新(Update)。
如果更新失败或无法修复您的设备，您必须将其恢复为出厂设置。这还将删除设备上所有本地存储的文档、照片和视频。
但是，您可以选择之后使用本地或 iCloud 备份来恢复丢失的数据(restore lost data with a local or iCloud backup)。您还可以取回任何同步到 iCloud 的数据（例如，如果您启用了iCloud 照片(iCloud Photos)，您的照片）或第三方云存储服务。
如果要继续，请选择“还原”(Restore)，然后选择“还原和更新”(Restore and Update)。
如果您改变主意并想要退出恢复模式，请先从Mac或 PC 上拔下设备。然后，按住侧面(Side)/顶部(Top)按钮，直到屏幕变暗。再次按住它，直到您在屏幕上看到Apple标志。(Apple)
恢复模式并不能解决所有问题(Recovery Mode Doesn’t Fix Everything)
更新或恢复您的 iPhone 或 iPad 可能会使设备再次工作。但是，恢复模式并不是解决所有问题的灵丹妙药。如果原因与硬件有关，如果设备仍然存在问题，那么您最好的选择是在当地Genius Bar(Genius Bar)预约。
How to Force Restart an iPhone and Enter Recovery Mode
Often, a simple restart is all іt takes to fix the odd issue on your iPhone. But rarely, you will come across serious рroblems that require уou to force restart and enter iPhone recovery mode instead.
For example, you may have an iPhone that gets stuck at startup, engages in a continuous boot loop, or doesn’t respond to touch. A force restart helps you reboot the non-responsive device, but going the extra step and entering recovery mode also gives you a shot at fixing the problem for good.
iPhone recovery mode gives you two options. You can update your iPhone with the latest version of iOS while keeping your data intact. Or, you can choose to reset it to factory settings. If you have a local or iCloud backup, you can also restore your data in case the device starts to function normally again.
That said, force restarting an iPhone, let alone entering recovery mode, can be a bit confusing since the process is different among the different iPhone models. The same goes for the iPad. You must make some basic preparations beforehand.
How To Prepare for iPhone or iPad Recovery Mode
To force restart an iPhone or iPad and enter recovery mode, you must have a Mac or a PC at hand. It’s best to use one that has a local backup of your iPhone or iPad since you may end up resetting the device. Otherwise, any Mac or PC will do since recovery mode does not require you to “trust” a desktop.
In macOS Catalina and newer, you must use the Finder app to interact with the iPhone or iPad once it’s in recovery mode. On macOS Mojave and earlier, as well as on Windows, you must use iTunes. If you use a PC and it doesn’t have iTunes, install it before you move on.
That said, start by connecting your iPhone or iPad to the Mac or PC via USB. You may have to use a USB-C to USB Adapter on a Mac that only has USB-C ports. Then, open Finder or iTunes. You are now prepped and ready to enter Recovery Mode.
How To Force Restart an iPhone and Enter Recovery Mode
Depending on your iPhone model, you have to use one of three different methods to force restart and enter recovery mode.
iPhone 8 Series, iPhone X, and Later
On the iPhone 8 series and later, which includes all iPhones with Face ID functionality (such as the iPhone X) as well as the Touch ID-based iPhone SE (2020), you must use a combination of three buttons to force restart and enter recovery mode. Press them in the following order:
1. Press and quickly release the Volume Up button.
2. Press and quickly release the Volume Down button.
3. Press and hold the Side (Sleep/Wake) button.
After a few seconds, the screen will go black and the Apple logo should show up. Keep holding until you see the recovery mode screen. You can then release the Side button.
iPhone 7 Series Only
The iPhone 7 and the iPhone 7 Plus require a two-button combination to force restart and enter recovery mode. Start by pressing and holding the Volume Down button and the Side button at the same time.
Keep holding both buttons while the screen goes black and the Apple logo shows up. Once you see the recovery mode screen, release both buttons.
iPhone 6s Series and Older
On the iPhone 6s, iPhone 6s Plus, and older iPhone models, simply hold down both the Home button and the Side/Top button.
The screen should go black, and the Apple logo should follow soon after. Continue holding until you see the recovery mode screen. You can then release both buttons.
How To Force Restart an iPad and Enter Recovery Mode
If you want to force restart an iPad and enter recovery mode, you must follow one of two methods depending on whether your device has a Home button or not.
iPads Without a Home Button
On iPads without a Home button, such as the iPad Pro (2018) and newer, press the following buttons in the correct sequence to force restart and enter recovery mode:
1. Press and quickly release the Volume Up button.
2. Press and quickly release the Volume Down button.
3. Press and hold the Top (sleep/wake) button.
Keep holding until the iPad force restarts and enters recovery mode. You can then release the Top button.
iPads With a Home Button
On all iPads with a physical Home button, such as the iPad Air (2019), hold down the Home and Top buttons at the same time.
Keep holding both buttons until the recovery mode screen shows up on the screen. You can then release both buttons.
How To Use Recovery Mode
Once you enter recovery mode on your iPhone or iPad, you will automatically see a pop-up notification in Finder or iTunes that will prompt you to either update or restore the device.
We recommend that you update your iPhone or iPad first. Select Update, and your Mac or PC will attempt to download and install the latest version of iOS or iPadOS without deleting your data.
If your device exits recovery mode and reboots automatically (which happens after 15 minutes), wait for the download to finish, re-enter recovery mode, and select Update again.
If the update fails or doesn’t fix your device, you must restore it to factory settings. That will also delete all locally stored documents, photos, and videos on the device.
However, you can choose to restore lost data with a local or iCloud backup afterward. You can also get back any data that was synced to iCloud (such as your photos if you had iCloud Photos enabled) or third-party cloud storage services.
If you want to go ahead, select Restore, and then select Restore and Update.
If you change your mind and want to exit recovery mode, start by unplugging the device from your Mac or PC. Then, hold down the Side/Top button until the screen goes dark. Hold it down again until you see the Apple logo on the screen.
Recovery Mode Doesn’t Fix Everything
Updating or restoring your iPhone or iPad will likely get the device to work again. However, recovery mode is not the silver bullet to every problem. If the cause is hardware-related, which is likely if the device still has issues, your best option would then be to book an appointment at the local Genius Bar.
