It looks like you're visiting on an iOS device. You cannot install IPSW files onto an iOS device without a computer. If you would rather continue on a computer, just visit this website on a computer. If you would rather install without a computer, close this modal and download the iOS beta profile.
Select your device from the dropdown to download it's firmware:
It's pretty simple. To install, download the corresponding file for your device, open iTunes on your computer, and plug in your device. After you have done this, go to your device in iTunes. Depending on whether you want to restore your device (start fresh or restore a backup onto the device) or update your device (just update you while keeping your apps and documents) you click a different button. To restore your device to iOS beta, click Restore while holding down Shift (Windows) or the Option key (macOS). For updating your device, to the same except with the Check for Update button. This will bring up a dialog where you can select the downloaded IPSW file. Your device will update to iOS beta now. Enjoy!
Why are some IPSWs for multiple devices?
That's what Apple did starting with iOS 10.0, they grouped them by feature set. Easier for me, I guess.
What if I download the wrong file?
iTunes will stop the process if it detects that you have the wrong file for your device. The only thing it will cost you is another download, so please read carefully.
Where did you get these file URLs?
From the Apple Developer Center.
How do I know these are real?
You aren't downloading the file from me. You are downloading it directly from Apple, as proved by the URL it downloads from. Also, if they weren't, iTunes would refuse to install them, as you cannot install modified IPSW files.
