A full week will be passed, even though Apple released iOS & iPadOS 13.7 to the general public and the (Cupertino-based), tech company, like clockwork, pulled the plug on its signage, of the ancient iOS & iPadOS 13.6.1 firmware for iPhones and iPads on Tuesday night.
“A rather predictable change means that after upgrading, to the newer iOS or iPadOS 13.7 release, iPhone and iPad owners are now unable to downgrade the firmware they run on their handset of choice”
It is not common for iPhone or iPad users to downgrade the firmware version of their device but it is a popular trend among jail-breakers who want to cash in on the benefits of 3rd party hacks and extensions that only support older iOS versions.
However, jailbreaking isn’t the only reason one would like, to downgrade the firmware of a device, and this is because sometimes software updates,can introduce frustrating insects to the user experience. Returning to an older firmware can provide temporary relief from such bugs, at least until Apple is able to release another software update to fix them.
It’s not that big of a deal for the jailbreak community that Apple no longer signs iOS or iPadOS 13.6.1, and that’s because the two latest software exploit-based jailbreaks, Odyssey and unc0ver, only support up to iOS and iPadOS 13.5. Currently,
Only the checkra1n tool can jail the latest versions of Apple’s mobile operating systems, because even though it relies on hardware-based bootrom exploit dubbed checkm8 which Apple can’t patch with software upgrades.
Apples reasoning to stop signing older versions of iOS remains a widely speculated phenomenon. Most evidently . Apple wants its users to ensure the best user experience by using the latest software. But one thing that Apple often brushes under the carpet is that the company does not want you to jail-b your device
Doing so makes getting to jailbreak-supported firmware versions more difficult. Apple also benefits from blocking downgrades by being in a position to gloat about new firmware adoption at its keynote presentations./Which versions of iOS or iPadOS are signed for your device can always be checked by visiting the handy online utility IPSW.me.
