So, you’ve gone back in time (digitally speaking). How do you know it actually worked? Several telltale signs will confirm your reversion was successful.

Check the Android Version: The most obvious step! Go to your device’s Settings, usually under “About Phone” or “About Device”. Look for the Android version number. It should now display the version you were aiming for – the one
-before* the update.
Inspect the User Interface: Remember those UI changes that drove you crazy? Are they gone? The layout, icons, and overall look and feel of the system should have reverted to their previous state. This is a visual confirmation that the system files have been replaced.
Test Functionality: Try out the features that were causing issues. Did the battery drain problem disappear? Is your favorite app behaving again? Run some basic tests to see if the core issues that prompted the reversion are resolved.
Review Pre-Update Apps: Some apps might have been updated to work with the latest Android version. Check if these apps function correctly or need to be reinstalled.

Restoring User Data from Backup

You didn’t forget to back up your data, did you? (Fingers crossed!) If you did, you’re in for a rough time, but let’s assume you’re a data-savvy individual. Restoring your data is essential to get your device back to its pre-update glory. The process depends on the backup method you used.

Google Account Backup: If you used Google’s backup, it’s usually the easiest. Sign in to your Google account on your reverted device. During the setup process, you should be prompted to restore from a backup. Follow the on-screen instructions. This typically restores your contacts, app data, settings, and sometimes photos and videos.
Local Backup: If you used a local backup (e.g., a backup on your computer or an external storage device), you’ll need to locate the backup file. The steps to restore vary depending on your device and the backup app you used. Consult your device’s manual or the backup app’s documentation for specific instructions.
Third-Party Backup Apps: If you used a third-party backup app, open the app and follow its instructions to restore your data. The process varies significantly between apps. Make sure you understand how to restore data
-before* you revert the update!
