I downgraded an iPad Pro the other day by connecting it to a Mac whilst it’s turned on, then put the iPad into DFU, iTunes then downloaded 10.3.2 and very quickly the iPad rebooted into iOS 10 without any problems.

It works if you are going from iOS 11 beta 1 down. Specific problem here is on iOS beta 2 down.

+++ Fixed Issue +++

For all those who have the problem of downgrading from iOS 11 beta 2 to iOS 10.3.2, I am aware that I have just managed to do this successfully. Here are the steps:

Start from:

iPhone 7 iOS 11 beta 2 (iPhone_7_11.0_15A5304i_Restore);

Put iPhone 7 in DFU;

Restore iOS 11 beta 1 from iTunes (iPhone_7_11.0_15A5278f_Restore)

Return it immediately to DFU directly from the welcome screen;

Restore iOS 10.3.2 from iTunes (iPhone_7_10.3.2_14F89_Restore);

The operation ended well and now I'm back to the stable version.

Best regards,

Vincenzo

2 Solutions to downgrade:

1. Downgrade from iOS 11 Beta 2 to iOS 10.3.3, then downgrade to iOS 10.3.2; you can use reiboot to do that;

2. Downgrade from iOS 11 Beta 2 to iOS 11 Beta, then downgrade to iOS 10.3.2; you can download the firmware and then restore your phone.

I managed to get down to 10.3.3, and you mentioned you can use reboot to do that, can you clarify?

can you give me a link of ipsw ios 11 beta 1 please? my iphone is in dfu mode

But how do i get iOS 11 Beta 1 and after that 10.3.2 on my iPhone? Its in DFU?

i don't know if it's allowed to put links here
but i suggest you to serach on youtube some videos put links of ios 11 beta 1 and 10.3.3 beta 4 or 5

for my case i have iphone 6s plus the only solution works for me is to restore my iphone by beta 2 -> beta 1 -> 10.3.3 beta5 -> 10.3.2

i hope that will works for you

i downgraded to 10.3.3 then all I did was used a back up I had on iCloud from a few days ago, done a factory reset and installed it from the back up, hey presto 10.3.2 working.

Im trying to follow your steps but with an iphone 6s (IPSW for 6s as well) and Itunes is says its not the compatible. Any suggestions?

this is an offical link from Apple https://beta.apple.com/sp/betaprogram/iosimagerestore

It is possilbe to skip the ios11 beta 1 and go straight to ios 10.3.3 beta from the link above.

como pudiste hacer o tenes alguna paguina de enlace donde pueda descargar nuevamente el ios 11 beta 1 o 2 ya que me quedo en modo restore y no puedo restaurar a la vercion 10.3.2 gracias

you can ONLY step back to 10.3.3 beta 5.. No earlier. Download the imaged and use it.
