※ 引述《sixf0ld (coldrain)》之銘言:
: iOS 11 Public beta 可以下載了
: https://beta.apple.com/sp/betaprogram/
: 手上只有一隻iphone所以不太敢下來玩玩
目前使用iPhone 6s升級到iOS 11 Public beta玩玩
發現想退回iOS 10,什麼方法都無法降級
beta 2 update 1又沒有6s的版本,只能等6s的update 1版本出來了
試過(以下說的升級降級都是利用DFU直接重灌無保留任何資料):
1. 直接降級成iOS 10.3.2 (X)
2. 直接降級成iOS 10.3.3 beta 4 (X)
3. 降到iOS 11 dev beta 1(可安裝並開機),再退回iOS 10.3.2 (X)
4. 裝好iOS 11 dev beta 1,關掉Find My iPhone、登出iCloud、登出iTunes、
刪除描述檔,灌回iOS 10.3.2 (X)
5. 升級到iOS 11 dev beta 2(可安裝並開機),再退回iOS 10.3.2(X)
有版友是使用6s,可以成功降級的嗎?都無法的話,目前只能使用iOS 11了QQ
