After updating to iOS 9.0.1, I'm unable to downgrade my device to a lower version. The process of downgrading iOS 9 to iOS 8.4 on iPhone consistently fails, and even reverting to iOS 9.0 is unsuccessful. Unsure if it's the device or my approach, seeking guidance from Mytour.vn to address this issue.

Greetings!

Previously, users could freely downgrade from iOS 9 to iOS 8.4. However, now, if users have updated to iOS 9 patches like iOS 9.0.1 or iOS 9.0.2, they won't be able to downgrade to iOS 8.4 or even iOS 9.0 anymore, as Apple no longer supports it as before.

If you've updated to iOS 9.0.1 on your iPhone and are experiencing issues with iMessage, iCloud storage, or toggling mobile data, consider upgrading to iOS 9.0.2 for your device.

To upgrade to iOS 9.0.2 on iPhone or iPad, users simply need to go to Settings => General => Software Update, then select Download and Install to apply this software update to their device.

The update process happens quite swiftly thanks to the small size of the patch. Typically, users complete this process in just 5-10 minutes.
