What is Recovery Mode?
Recovery mode is a special boot-enabled partition that allows users to troubleshoot or repair issues on their devices when normal operation is not possible (Wired). It provides access to advanced tools, system utilities, and reinstallation options outside of the main operating system.
Recovery mode goes by different names depending on the device platform or manufacturer. For example, it may be called “Download mode” on Samsung devices, “Restore mode” on iPhones, or “Fastboot mode” on Android devices (Collins Dictionary). But the purpose is generally the same – to revive or repair a device when standard methods have failed.
The key functions offered in recovery mode allow wiping device data, restoring firmware, applying system updates, resetting passwords, and more. It provides a last resort option when normal booting is not possible due to software issues, corrupted files, or other system problems. Recovery mode gives users a way to fix devices and avoid data loss in the event of a serious crash or malfunction.
Entering Recovery Mode
Entering recovery mode allows you to access advanced reset and restore options on your device. The way to enter recovery mode differs slightly depending on your device platform.
How to Enter Recovery Mode on iPhone
To enter recovery mode on an iPhone 8 or later, including iPhone SE 2nd generation, follow these steps (source):
- Press and quickly release the Volume Up button.
- Press and quickly release the Volume Down button.
- Then, press and hold the Side button until you see the recovery mode screen.
For older iPhone models like the iPhone 7 or earlier, press and hold the Home and Power buttons together instead of the Side button in step 3.
How to Enter Recovery Mode on Android
To enter recovery mode on Android devices, the steps can vary slightly by model. Generally, you’ll need to boot into recovery mode using a special hardware key combination on your device. Common ways include (source):
- Holding Volume Up + Power
- Holding Volume Down + Power
- Holding Home + Power
You may need to try a couple combinations to enter recovery mode on your specific Android device.
How to Enter Recovery Mode on Other Platforms
On Windows PCs, you can access the recovery options by rebooting and selecting “Advanced startup options” (source). On Macs, hold Command + R while booting to enter macOS Recovery (source). Check your device’s support documentation for specific key combinations to enter recovery mode.
What Happens in Recovery Mode
When an Android device enters recovery mode, its functionality becomes limited and it prevents a normal system boot. The main purpose of recovery mode is to allow users to restore device firmware or perform a factory reset in order to fix software issues that are preventing normal operation.
While in recovery mode, most standard device features are unavailable. Users cannot access the normal Android user interface, launch apps, make calls, browse the internet, or use other typical device functions. The touchscreen interaction is also limited. This prevents users from accidentally disrupting the recovery process.
Instead, recovery mode provides access to the recovery menu and allows users to apply official firmware updates from their phone manufacturer. This firmware restore can fix system file corruption, software bugs, or other issues that are preventing the device from booting up properly. Performing a factory reset from the recovery menu can also wipe the user data partition and restore the device to default settings.
Overall, the limited access and functionality of recovery mode is by design. By blocking normal system boot and restricting software access, recovery mode provides a safe environment for restoring device firmware when standard operations have been disrupted. This recovery partition and menu allows users to revive an Android phone and regain full functionality after major software issues occur.

Restoring Firmware
One of the main uses of recovery mode is to restore or reinstall the iPhone or iPad’s firmware. This can fix major software issues and bugs. The process involves connecting the iPhone to a computer with iTunes or Finder and initiating a restore (Apple Support).
Restoring firmware requires a connection to a computer with the latest version of iTunes (for older iPhones) or the Finder app (for newer iPhones). The computer will communicate with Apple’s servers to download a fresh copy of the firmware file to install on the device. This will completely wipe the device and restore it to factory settings.
It’s important to note that restoring firmware will erase all data, settings, apps and media on the iPhone, essentially resetting it to the state it was in when you first purchased it. So before initiating a restore in recovery mode, it’s best to backup your data either to iCloud or locally on your computer. The restore process cannot be reversed once started.
Exiting Recovery Mode
There are a few ways to exit recovery mode on an iPhone:
The normal way is to simply reboot the device. To do this, press and hold the Side button until you see the Apple logo appear on the screen. This will restart the iPhone and boot it up normally, exiting recovery mode in the process (Source: https://www.lifewire.com/get-into-and-out-of-recovery-mode-2000261).
If the normal reboot method doesn’t work, you can try force restarting the iPhone. To do this, quickly press and release the Volume Up button, then quickly press and release the Volume Down button, then press and hold the Side button until the Apple logo appears. This will force the device to restart, which should exit recovery mode (Source: https://discussions.apple.com/thread/254273767).
As a last resort, unplugging the iPhone from its connected USB cable can also sometimes kick it out of recovery mode. After unplugging, wait a few seconds then plug the USB back in and try rebooting the iPhone normally (Source: https://www.imyfone.com/iphone-issues/how-to-get-iphone-out-of-recovery-mode/).
Risks of Recovery Mode
Entering recovery mode does come with some risks that users should be aware of. The two main risks are getting stuck in recovery mode and potentially bricking your device if the process gets interrupted.
It’s possible for a device to get stuck in recovery mode if there is an underlying hardware or software issue preventing it from successfully exiting this mode (1). This could happen due to corruption in the firmware, OS issues, or hardware damage. If a device gets stuck, it usually requires connecting it to a computer to force exit recovery mode or restore the firmware/OS.
Additionally, if the recovery mode process gets unexpectedly interrupted, such as the device losing power or disconnecting from the computer, this can potentially brick the device – rendering it unusable (2). This is because the firmware or OS may be corrupted if an update gets interrupted. Bricking is more likely to occur if using unofficial firmware or tools to enter recovery mode.
To minimize risks, it’s recommended to use official tools from Apple or your device manufacturer to enter recovery mode, avoid interrupting the process, and have sufficient battery charge. Overall, while recovery mode does carry some risk if used improperly, it is generally a safe feature when used correctly.

When to Use Recovery Mode
Recovery mode can be useful in certain situations when your phone experiences major software issues that prevent normal functioning. The most common times to use recovery mode include:
System crashes – If your phone experiences a serious crash that causes it to be stuck on the Apple logo, restart loop, or blank/black screen, recovery mode may help restore firmware and get it working again. Recovery mode essentially resets the phone’s software without deleting data.
Stuck bootloops – Similarly, if your phone gets caught in a continuous bootloop where it constantly restarts without progressing, recovery mode can interrupt the loop and initiate a firmware restore to fix software corruption.
Firmware issues – Sometimes a failed iOS update can cause firmware problems that break core functions. Putting the phone in recovery mode allows you to connect to iTunes and reinstall firmware to resolve the issues.
Overall, recovery mode is most useful for major software-related problems where the normal boot process is disrupted. It’s an effective troubleshooting step before resorting to a full factory reset or data wipe. Refer to Apple’s support guide for specific situations where recovery mode is recommended.
Alternatives to Recovery Mode
Instead of putting your device into Recovery Mode, there are some other options you can try to repair your device or operating system:
Factory Reset
Doing a factory reset will erase all data and settings and restore your device back to its original state when you first purchased it. This can fix many software issues, though you will lose all files and customizations. On an iPhone, a factory reset can be performed by going to Settings > General > Reset > Erase All Content and Settings. For instructions on factory resetting other devices, check the manufacturer’s support documentation.
