App Downgrade Method: The downgrade process utilizes the native system mechanism; account re-verification is not required.
StoreKitUI Fallback: This fallback option is used if the minimum iOS version supported by the target app version exceeds the device's current iOS version.
You can find the specific version number in the top-right corner of the version page.
I actually managed to pull it off—I can't believe it.
I performed a tethered downgrade on an iPhone XR from iOS 18 to iOS 14.0 beta 4, without any saved SHSH blobs.
The video demonstrates the tethered boot process, meaning the device requires a specific startup method every time it is rebooted; it is not a standard or permanent downgrade.

Things are finally moving again after a long hiatus.
Alfie has managed to bypa*ss SPTM, which will allow developers to continue working on adding support for iOS 17.0.1–17.2.1 to Dopamine.
As always, there are no specific dates.

- Supports A12-A13 devices
- Works with RP2350 + usbliter8 exploit
- Fully automated — DFU → PWNED → Wipe with a single click

⚠️Important points to note:
* Tethered Jailbreak:
This is a tethered jailbreak, meaning you will need an RP2350 device (external hardware) to rerun the exploit every time the device is rebooted.
* SEP is not bypassed:
The Secure Enclave Processor (SEP) has not been compromised, so features like Face ID, Touch ID, and Keychain will not work.
* User data on iOS 17 and above:
On devices running iOS 17 or later, the /var partition is encrypted by SEP, so user data cannot be accessed without SEP cooperation.
* iOS version support:
The project has been tested on several versions, starting from iOS 17.0 up to iOS 27 Beta, with varying degrees of support depending on the targeted component (iBoot, SPTM, TXM, and Kernel).
🚀 RAMDISK and jailbreak are coming soon; this may not be the first achievement in this field, but it certainly won't be the last.

We've added a new update.
Now, you can modify the system methods and add SpringBoard methods manually, along with important fixes.
