Verdict: Highly Recommended (with caveats). Downgrading your iPad 2 from the sluggish iOS 9.3.5 to iOS 8.4.1 is one of the most effective ways to breathe life back into the device. However, it is not a simple "click restore" process. It requires using a special "trick" that exploits Apple's still-signing OTA (Over-The-Air) update for iOS 6.1.3.
Bottom Line: If your iPad 2 feels like it's wading through molasses on iOS 9, do this. The performance improvement is dramatic. But be prepared to lose modern app support.
Downgrading isn’t without its downsides. Here’s what you lose:
| Aspect | iOS 9.3.5 | iOS 8.4.1 | |--------|-----------|-----------| | Modern App Support | Good (many apps require iOS 10+) | Poor. Many apps now require iOS 10 or 11. You'll need older app versions. | | Security | Last update 2018 | Last update 2016 (vulnerable to several exploits) | | iCloud/Service | Works fully | iCloud Drive, Messages, Mail work. Some new features missing. | | Method | Official restore | Unofficial "OTA spoof" method |
You cannot simply download an iOS 8.4.1 IPSW and restore. Apple stopped signing it years ago. The method below exploits Apple still signing iOS 6.1.3 for the iPad 2, then updates from iOS 6 to iOS 8.4.1.
It’s a geeky, functional downgrade — not for average users — but for iPad 2 owners who find iOS 9 unbearable, iOS 8.4.1 is a stable, faster alternative.

Downgrading an iPad 2 from iOS 9.3.5 to 8.4.1 is a specific and somewhat advanced topic. Because Apple stopped signing iOS 8.4.1 many years ago, a standard restore via iTunes is impossible.
However, for the iPad 2,3,4 (specifically the iPad 2), there is a well-known loophole involving the "Odysseus" method. Note: This does not work on the iPad 2,1 (WiFi only model) as easily, and it generally requires the device to be on iOS 6.0–6.1.3 to set up, or requires a "re-restore" trick if you were previously on 8.4.1.
Here is a helpful guide covering the realities, the requirements, and the process.
We will use the OdysseusOTA2 method. This is the most reliable method as of 2025. It works by tricking your iPad into requesting the old, still-signed OTA update.
