How to download and install iOS 12 GM:
Step 1: Before you can go ahead and download iOS 12 GM, you need to first enroll yourself into Apple Developer Program at https://developer.apple.com/programs/. If you are already registered on it, simply skip to Step 2.
Step 2: Login to Account section of Apple Developer Program using your Apple ID: https://developer.apple.com/account/.
Step 3: Now you will need to register your UDID with Apple for the iOS device you want to install the GM on. To find the UDID of your device, simply plug your device into iTunes, select it, and then click on the serial number for it to show the UDID, like shown in the screenshot below. Now copy this number using ctrl+c on Windows, or command+c on Mac.
Step 4: From the main Account section of the page, Click on Certificates, Identifiers & Profiles.
From the Devices section found in the left panel, click on All.
Now from right hand panel, click on “+”, and then add the UDID of your iOS device.
Step 5: Once the UDID has been added, head to the Develop > Downloads section. You can find this page directly at https://developer.apple.com/download/.
Now from here, select your device from drop down to begin downloading the required iTunes-restorable iOS 12 GM firmware file.
Alternatively, you can also choose to install iOS 12 GM using OTA update method. For that, open the same download page as mentioned above directly on your iOS device, then click on ‘Download’ under iOS 12 beta and alongside Configuration Profile, and then allow it to install on your iOS device (this may require a restart). Once the profile is set, head to General > Settings > Software Update on your device and wait for iOS 12 OTA update to show up. Once it is available, tap on Download and Install to get onto the new firmware version.
Step 6: Coming back to the iTunes-restorable firmware download method, make sure that iTunes installed on your Windows PC or Mac is the latest version. Once you are sure it’s on the latest version, launch iTunes and also connect your iOS device to the computer.
Step 7: Now to install the GM seed, Mac users need to hold the Alt key, for Windows users this will be the Shift key, and then click on the Restore iPhone… button. iTunes will now prompt you to select the ipsw firmware file. Select iOS 12 file you downloaded earlier.
Step 8: Now sit back and relax as iTunes installs iOS 12 on your iPhone, iPad or iPod touch. Be patient as this could take some time depending on the speed of your computer and the type of device you are installing it on. Once installed, your device will reboot automatically and you’ll be greeted with Hello screen of iOS 12. Happy testing!
