Way 1: Downgrade from iOS 15/10.3.3 Beta to iOS 14.8/10.3.2 with iTunes

What you need to do first to go back to iOS 10.3.2 on iPhone or iPad in question with iTunes is to have the iOS 10.3.2 IPSW file downloaded on your computer.

To do so, visit this site and download the respective IPSW file for your device.

Then you need to turn off Find My iPhone. Just go to Settings > iCloud > Find My iPhone > Turn it off.

Next, Connect your iOS device to computer, launch iTunes and put iOS device into DFU mode.

For iPhone 8/ 8 Plus and newer: Quickly press the Volume Up button and then the Down button. Long press the Sleep/Wake button until the screen turns black, then hold down both the Sleep/Wake button and Volume Down button. Last, just release the Sleep/Wake button and wait for a few seconds.

For iPhone 7/ 7 Plus: Press and hold the Sleep/Wake button and the Volume Down button simultaneously for 5 seconds. Then release the Sleep/Wake button while continuing to hold the Volume Down button for extra 5 seconds. If the screen stays black, that's it!

For other old iOS devices: Hold down the Home and Power button. Keep holding Home and power button until the device screen turns to black. Release Power button to keep holding home for 10 seconds.

iTunes will alerts after detected an iPhone (or iPad/iPod) in recovery Mode, and asked you to restore your device. Simply click "OK" to confirm.

Then you have to Search your device icon on iTunes and click it > Choose Summary tab and,
On Mac, press "Option" and click "Restore iPhone (or iPad/iPod)..."; on Windows PC, hold on the Shift key instead. Then, click on the Restore iPhone/iPad.

Next up, you will have to browse and choose the IPSW file you have just downloaded. You will see a pop up telling that you are going to downgrade, just click Update and Restore to proceed.

Way 2: Uninstall iOS 15/10.3.3 Beta and Go Back to iOS 14.8/10.3.2 without Data Loss

As you can see, the process of uninstalling iOS 10.3.3 beta and going back to 10.3.2 with iTunes is so complicated. Worse still, some users are experiencing iPhone stuck in recovery mode when downgrade to iOS 14.8/10.3.2 from iOS 15/10.3.3. So, I would not suggest you to use the method above.
