Tethered Downgrade for future jailbreak
#1
Hello guys !

I've got a few questions about downgrading :

First, let me inform you that I'm currently on a iPhone XS with iOS 12.0 jailbroken with Chimera, with no blobs saved.
I've always been blocked on this version, because iOS version are always unsigned before the jailbreaks tools come out, and I never took the risk of upgrading and loose a jailbreak.

But now, I would like to upgrade to iOS 13.3 as it's still signed (because iOS 13.3.1 isn't a good firmware for a future jailbreak) for saving blobs, and be able to restore in the future, if any bug comes out while jailbreaking or testing tweaks.
I know that i won't be able to restore to ios 12 whithout blobs... But, during my researchs, I've heard about tethered downgrading : I understood that it would be possible to restore to a custom firmware flashed with someone else's blobs, or that it is possible to patch an unsigned version (please correct me if I'm wrong ^^), but that they wil lead to a permanently tethered jailbreak. Since the actual jailbreaks tools need and IPA to be launched, I don't mind that aspect.

I would like to confirm those methods with you guys, and ask you, what are my current possibilities !

My conclusion of this situation would be to save my tweaks and configuration, upgrade to 13.3, save blobs, and wait ! Or wait for a ios 13 jailbreak maybe iOS 14 ?

Thank you guys for your answers Smile Have a great WE Smile

You are indeed right, a radical measure would be a tethered downgrade, BUT, your device cannot do it. We can downgrade tethered but only the CheckRa1n devices (iPhone X and older) because they support the CheckM8 BootROM exploit. iPhone XS does not, and it's therefore impossible to restore a CFW currently. I'd stay put for now. Save the blobs for iOS 13.3 (On A12 you need to set a generator first, google it).
