I have an iPhone 6 (32 GB) running iOS 12.5.2, and trying to dual boot iOS 11.0. Whenever I hit the ‘dual boot’ button it says : ‘Failed to copy MobileAsset to COPY directory’.
However, when I go into the COPY directory, MobileAsset is there. I’ve read the other post about the 5s but that didn’t help me, I even tried deleting and installing the designated iOS ipsw (11.0) but still no luck.can anyone help?
