Can apples drop from 12 to 1 1?

Downgrading is risky. Remember to back up before demotion! If there is no backup data before upgrading the iOS 12 system, it is not recommended to downgrade. Due to the large span of the system, information such as SMS may be lost during the degradation process. If the content of your message is very important, I suggest forbearance, because the official version can be upgraded soon.

If you don't have a synchronization assistant installed on your computer, download a "synchronization assistant" from the synchronization assistant official website and install it on your computer.

Open the synchronization assistant, connect the mobile phone and the computer with the data cable, and click "Brush Prison Break" in the menu above. After entering, the system will automatically detect the firmware and provide downloadable firmware. Click 1 1.4 to download the firmware.

Open Itunes, click the device logo, and then enter a device summary. Click "Back Up Now" to back up the data of iOS 12, in case of data loss after demotion!

After downloading the firmware, select "shift+ Update" to select the newly downloaded firmware! Generally, other data will not be lost, except SMS!

Next, Itunes will automatically install the firmware, so you just have to wait patiently!

Note: Do not disconnect the data cable of the mobile phone and turn off the computer during the upgrade, otherwise the upgrade will fail or data will be lost!
