To put your iPhone 8 or later models, including the iPhone SE (2nd generation), into recovery mode without a computer, you can follow these steps:
1. Start by ensuring that your iPhone is turned off. If it’s already on, press and hold the power button until you see the slide to power off option. Slide it to power off your device.
2. Once your iPhone is powered off, locate the volume up button on the left side of your device.
3. Press and quickly release the volume up button. Be sure not to hold it for too long, as this may cause your device to enter the wrong mode.
4. Next, locate the volume down button, which is just below the volume up button.
5. Press and quickly release the volume down button. Similar to the previous step, make sure not to hold it for too long.
6. After releasing the volume down button, locate the side button (also known as the power button) on the right side of your iPhone.
7. Press and hold the side button until you see the recovery mode screen. This may take a few seconds, so be patient.
The recovery mode screen will display the iTunes logo and a lightning cable pointing towards it. At this point, your iPhone is in recovery mode.
It’s important to note that entering recovery mode without a computer is useful when you need to troubleshoot or restore your device, but you’ll still need a computer with iTunes installed to perform further actions, such as restoring or updating your iPhone.
If you want to exit recovery mode without a computer, you can simply force restart your iPhone. To do this, press and hold the side button and volume down button simultaneously until the Apple logo appears on the screen. Your iPhone will then boot up normally.
I hope these steps help you put your iPhone 8 or later models into recovery mode without a computer. If you encounter any issues or have further questions, feel free to ask.
