Restoring your iOS device to firmware released at an earlier date is as common as upgrading to new releases. Reason being a new release may come with under the hood issues which have, in the past, affected normal phone use. Examples include problems with performance, battery life among other functionality issues. Most of which take days for Apple to resolve. You can easily solve such by downgrading to previous iOS versions or, as this article highlights, can select and restore custom IPSW with iTunes for iPhone, iPad and iPod on Windows/Mac. Downgrading is an option achievable by simple clicking the Restore button in iTunes. But some users would rather install custom firmware. Read on.
An IPSW file is one used by Apple Inc. to add new features, restore software on a device to its default factory settings and, at times, address security loopholes in iOS devices - iPhones, iPods and iPads- compatible with the release. With it, users of iOS devices can install the firmware, which is released in an archived, compressed format, through iTunes on either Windows or Mac. When decompressed, the files hold PLISTs, BBFWs, DMGs, IM4Ps files among others. All of which are encrypted.
The IPSW is an archived file format and can, therefore, be converted easily by using any unzip software. Other than for tinkering or educational purposes, there shouldn’t be any reason to decompress an IPSW file. Unless you know what you are doing, decompressing it renders the package unfunctional since it loses the communication link between your iOS device and iTunes. You can’t blame a human for trying though.
Custom IPSWs are bundled with features not present in default IPSW files. Features such as a preserved baseband. Take note that Find My iPhone must be turned off before restoring and restoring is possible on both Macs and Windows PCs.
The software is made accessible to the public on iTunes but since some people love us much more than we think you can download IPSW files from some trusted websites. IPSW downloads (https://ipsw.me/) being one.
