In this guide, we will discuss the process of downgrading your iOS device from the current version to iOS 10.2. This process can be useful if you are experiencing issues with the latest iOS update or if you prefer the features and functionality of iOS 10.2. Following the steps provided will allow you to successfully revert back to iOS 10.2.

Understanding iOS Updates

Before discussing how to go back to iOS 10.2, it’s essential to understand how iOS updates work. Apple regularly releases new versions of their operating system to improve security, fix bugs, and introduce new features. While these updates are generally beneficial, they can sometimes cause problems for users. Some users may experience issues with new updates, such as slower performance or compatibility issues with apps and software.

If you’re experiencing problems with a new iOS update, you may want to go back to a previous version. However, this process isn’t always simple, and there are some important things to consider before attempting to downgrade your device.

The Risks of Downgrading

Going back to a previous version of iOS can be risky, and it’s not recommended unless you’re experiencing significant problems with your device. Downgrading your device can cause data loss, and it may not be possible to restore your device to its previous state.

Additionally, Apple doesn’t support downgrading to previous versions of iOS, so you’ll be on your own if you run into any issues. Before attempting to downgrade your device, it’s essential to back up your data and be prepared for the possibility of data loss.

Compatibility Issues

Another important factor to consider when downgrading your device is compatibility issues. Some apps and software may not be compatible with older versions of iOS, so you may experience issues with functionality or performance.

Before downgrading your device, it’s crucial to research which apps and software may be affected and whether there are any workarounds or updates available.

If you’ve decided to go back to iOS 10.2, there are a few steps you’ll need to follow. The process is relatively straightforward, but it’s essential to follow each step carefully to avoid data loss or other issues.

Step 1: Back Up Your Data

Before downgrading your device, it’s essential to back up your data to avoid losing any important information. You can back up your device using iTunes or iCloud.

To back up your device using iTunes, connect your device to your computer and open iTunes. Click on your device icon in the upper left corner, and then click “Back Up Now.”

To back up your device using iCloud, go to Settings > iCloud > Backup, and then select “Back Up Now.”

Step 2: Download the iOS 10.2 IPSW File

To downgrade your device to iOS 10.2, you’ll need to download the iOS 10.2 IPSW file. You can download this file from various sources online, but it’s essential to ensure that you’re downloading it from a reputable source.

Once you’ve downloaded the IPSW file, save it to your computer.

Step 3: Disable Find My iPhone

Before downgrading your device, it’s essential to disable Find My iPhone. To do this, go to Settings > iCloud > Find My iPhone and turn it off.

Step 4: Connect Your Device to Your Computer

Connect your device to your computer using a USB cable.

Step 5: Enter DFU Mode

To downgrade your device, you’ll need to enter DFU (Device Firmware Update) mode. To do this, follow these steps:

  1. Press and hold the power button for three seconds.
  2. While still holding the power button, press and hold the home button for ten seconds.
  3. Release the power button but continue holding the home button for an additional ten seconds.

Your device should now be in DFU mode.

Step 6: Install iOS 10.2

Once your device is in DFU mode, open iTunes on your computer. Hold down the Alt/Option key (Mac) or the Shift key (Windows) and click on “Restore iPhone.”

Select the IPSW file you downloaded in Step 2, and then click “Open.” iTunes will now install iOS 10.2 on your device.

Step 7: Restore Your Data

After the installation is complete, you can restore your data using the backup you created in Step 1. To do this, connect your device to your computer, open iTunes, and click on your device icon. Click “Restore Backup” and select the backup you created.

FAQs for How to Go Back to iOS 10.2

What is iOS 10.2?

iOS 10.2 is an old operating system version for Apple devices that was released in December 2016. It includes various changes and improvements, such as new emojis, wallpapers, features for the Camera app, bug fixes, and security updates.

Why would someone want to go back to iOS 10.2?

There could be many reasons why someone wants to revert to iOS 10.2. For example, they may not like the new features or design of the newer versions, or they have experienced issues with performance, battery life, or apps compatibility. Moreover, some apps or devices may require iOS 10.2 to work properly.

Can I downgrade from a newer iOS version to iOS 10.2?

In general, Apple does not allow downgrading to previous iOS versions. Once you update to the latest version, or even a newer one, it is not possible to simply revert back to an older one. The primary reason for this is because Apple stops signing the older versions after a certain period, which means that it cannot be downloaded or installed on the device.

Is there any way to go back to iOS 10.2?

If you have previously saved the SHSH2 blobs or blobs of the iOS 10.2, you can use some third-party tools like Prometheus or FutureRestore to sign them and restore your device to iOS 10.2. However, this is a very technical and risky process that requires expertise and advanced knowledge. Additionally, even if you manage to downgrade, some features or apps may not work properly or encounter errors, so it is not recommended for all users.

What are SHSH2 blobs?

SHSH2 blobs are digital signatures or certificates that are unique to each iOS device and version. They are used by Apple to verify and activate the software during the restore or update process. By saving the blobs of a particular iOS version, you can potentially use it to downgrade to that version, even if Apple no longer signs it. It is recommended to save SHSH2 blobs for your current iOS version and future versions, in case you need to downgrade for any reason.
