Apple WWDC2 1 Global Developers Conference was successfully held yesterday. A brand-new ios 15 system was released at the conference, which supports the update and upgrade of iPhone6s and above. Some friends still don't know how to upgrade IOS 15, so let's take a look with Bian Xiao.

How to upgrade ios 15

detail

1. Copy this /iavUPXAW 1g, and then open, download and install the iOS 15 beta description file in Safari browser.

2. After installing the description file of iOS 15 beta, restart the iPhone, and then open Settings-General-Software Update, and drop down to receive the update prompt of iOS 15 beta.

Note: Remember to open the Settings-General-Description file and delete the iOS 14 beta description file before installing the fruit powder with the iOS 14 beta description file installed.

Finally, I need to remind you that because it is the first beta version of iOS 15, there may be unknown bugs. If you want to upgrade the early adopter fruit powder, remember to back up the important information on your mobile phone before upgrading. In order to avoid an upgrade error, the information on the iPhone will be lost!
