Don’t like iOS 11 on your iPhone or iPad? You can downgrade to iOS 10.3.3 if you act quickly. Maybe you don’t like the update, maybe you find iOS 11 battery life to be poor, or app compatibility to be a problem, or perhaps you think the performance is subpar. Whatever the reason, you can easily downgrade iOS 11 if you need to, but the ability to downgrade is only available for a limited time while Apple continues to sign the prior operating system release of iOS 10.3.3.

We’ll walk through how you can downgrade iOS 11 back to iOS 10 on an iPhone or iPad.

This guide requires iTunes and a computer, internet access, an iOS 10.3.3 ISPW file, and a USB cable. There is no way to downgrade iOS 11 without iTunes and a computer.

Important note: downgrading iOS 11 to iOS 10.3.3 can cause data loss, including the removal of important data or everything on your iPhone or iPad. Thus it is critical to have a backup that is compatible with iOS 10 available before downgrading (one should have been made prior to updating to iOS 11 in the first place), this is because iOS 11 backups are not compatible with iOS 10 or other prior releases. If you only have a backup for iOS 11, then downgrading to iOS 10 may require you to update again to iOS 11 in order to restore from that iOS 11 backup. If you don’t know what you are doing and do not have adequate backups, do not attempt to downgrade or you may experience permanent data loss on the iPhone or iPad.

We’ll cover two ways to downgrade, a simple way that should work for most users, and an approach that requires Recovery Mode if the first downgrade method fails.

Many Mac users who are attempting to download macOS High Sierra from the Mac App Store will find that a small 19 MB version of “Install macOS High Sierra.app” downloads to the /Applications folder of the target Mac, rather than the complete 5.2 GB Installer application for macOS High Sierra. This is annoying because it prevents a single download from being used on multiple computers, plus the small installer requires an internet connection during usage to download the rest of the High Sierra update files. Additionally, the tiny 19 MB incomplete installer prevents users from being able to create a macOS High Sierra USB installer drive or other custom update options available through the command line, like skipping the APFS update.

This tutorial will show you a workaround trick that allows Mac users to download the full macOS High Sierra “Install macOS High Sierra.app” file at 5.2 GB with the complete installer tool set and all dmg files and associated Install macOS High Sierra.app/Contents/Resources/ tools, rather than the tiny incomplete truncated installer at 19 MB.

Why do some users get a small incomplete version of macOS High Sierra installer from the App Store?

This is not yet known, but it happens with the final version of macOS High Sierra installer as well as with some of the beta versions.

It is unclear why some users will get a 19MB version of “Install macOS High Sierra.app” when downloaded from the App Store, while others users will get the complete 5.2GB version of “Install macOS High Sierra.app” when downloading from the App Store. Interestingly, once a user ends up with the 19 MB version of the incomplete installer, that seems to be the only thing that will download for that user regardless of how many times the incomplete installer app is deleted and re downloaded.

The installer size and completeness inconsistency appears random, and has no relation to disk space, beta enrollment, software catalog, and other theories seem to be incorrect as well.

Recently I discovered the pi’s in my quest for making a device with recognition software to locate items on the ground while being attached to a multi-rotor helicopter.

The Raspberry Pi is perfect. only needing 5v to run means its great for running off batteries etc. anyway to the streaming part.

To stream to VLC from your Raspberry Pi Camera to your computer over a network you need to install VLC Player on both the Raspberry Pi & PC/ Mac what ever.

for the PC/ MAC its simple just go to the VLC downloads page – http://www.videolan.org/ as for the Pi its more complicated.
