Introducing Vieux tool for iOS downgrades using OTA Blobs

Last Updated on 2 years by admin

Matthew Pierson is introducing a new Vieux tool for iOS downgrading. He is also known as Matty / @mosk_i on twitter. Vieux is the fastest tool for OTA downgrade so far. It’s written in Python. Hence this is the OTA downgrade method, you don’t need SHSH blobs.

Previously he released iOS 10.3.3 OTA Downgrade Script for the iPhone 5s using checkm8. However, he no longer maintained that script and advised users to use VIEUX instead of the script.

Currently, Vieux support for downgrade following iOS versions and devices. More 32-bit devices support will be added soon. You can also run the “./vieux -l” to list all compatible devices and iOS versions.
