Is this your current situation?
- You own an iPhone that has a physical home button (iPhone 7, 8, SE)
- You accidentally upgraded to the newest firmware, and you wish to downgrade to the older firmware.
Not an issue at all!
Step 1: Simply load up the Chubby Buttons app, and progress to the last screen where It says the latest firmware Is already Installed. (Pic below)
Step 2: Tap the snowboarder 5 times and then the app will begin to downgrade your Chubby Buttons to the previous firmware!
You're all set!
