Ok guys, ive spent all night trying to downgrade my iPhone 7, which is gsm not global, from ios 11 beta 2 to ios 10.3.2. A lot of people do not understand that directly downgrading from the ios 11 beta 2 ipsw to the ios 10.3.2 ipsw will cause a brick on your iphone, to insure this does not happen, follow these steps.
First put your iphone in dfu mode
- leave phone on while connected to computer
- hold power button for 3 seconds
- then hold the volume down button for 10 seconds
- your phone screen should be black and itunes shouldve displayed a message saying that the iphone needs to be restored
congrats step 1 is complete
now to downgrade your ios 11 beta 2 software to ios 11 beta 1
- download this file on your computer (

- now once its downloaded, go into itunes and on windows hold the shift key while simultaneously clicking on restore. this will allow you to install the beta 1 ipsw.
- select the file
- restore the device.
- then just follow the prompts on screen until you get back to the home screen.
