method used to trick an iPad 2 into thinking it is running an older version of iOS, thereby triggering an "OTA" (Over-the-Air) downgrade to iOS 8.4.1 Why this method is used

The iPad 2 often struggles with performance on iOS 9.3.5. Because Apple still signs iOS 8.4.1 as an OTA update for the iPad 2 (to allow users to bridge to newer versions), you can force the device to "update" backward. The "Interesting Paper" Method (Summary)

To perform this downgrade, users typically follow these steps:

: You must jailbreak the iPad on iOS 9.3.5 (using tools like ) to gain root access to the file system. Edit SystemVersion.plist : Use a file manager like to navigate to /System/Library/CoreServices/SystemVersion.plist Spoof the Version : Change the ProductVersion ProductBuildVersion Reboot and Update

How to Update an Old iPad from iOS 9.3.5 | Expert Q&A - JustAnswer

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.

Important Caveats (Read Before You Start)

Downgrading isn’t without its downsides. Here’s what you lose: App Support: Many modern apps require iOS 10 or later

• App Support: Many modern apps require iOS 10 or later. You will be stuck with older versions of apps (e.g., YouTube, Netflix, Spotify). You can download the last compatible version from the App Store, but some functionality may be missing.
• Security: iOS 8.4.1 has known vulnerabilities. Do not use this device for sensitive banking or logging into critical accounts.
• iCloud & Services: iCloud backup, iMessage, and FaceTime still work, but some newer iCloud features may not.
• No going back (easily): Once on 8.4.1, you can upgrade back to 9.3.5, but you cannot go to any other version.

The Major Problem: App Support

This is the dealbreaker for many.

• App Store: When you try to download modern apps (e.g., Facebook, Discord, modern banking apps), it will say "This app requires iOS 10.0 or later."
• Solution: You can download the last compatible version if you've previously "purchased" (even free) the app. Go to Purchased tab → tap cloud icon → it will offer the older version.

Apps that still work well on iOS 8.4.1: Spotify (old UI), Apple Music, iBooks, Podcasts, Mail, Notes, iMovie (comes free), GarageBand, Weather, Maps.

Apps that do NOT work: Most 2020+ games, Zoom (requires iOS 10+), Slack (requires iOS 11+), TikTok (requires iOS 11+).

The Easier Alternative: "Dual Booting" (CoolBooter)

If you do not have saved SHSH blobs, or if you find the Odysseus method too technically difficult, there is an alternative if your iPad 2 is already Jailbroken on iOS 9.3.5.

CoolBooter is a tool that allows you to install iOS 8.4.1 alongside iOS 9.3.5.

1. Jailbreak iOS 9.3.5: Use the Phoenix jailbreak tool (available via Cydia impactor or webclip).
2. Open Cydia: Add the necessary repositories (sources) for CoolBooter.
3. Install CoolBooter: Search for the iOS 8.4.1 installation.
4. Partition: The tool will resize your storage to make room for the second OS.
5. Boot: Once installed, an app on your home screen will let you switch between iOS 9 and iOS 8.

Pros of CoolBooter:

• No need for SHSH blobs.
• No need for a computer during the process.
• You keep iOS 9.3.5 (for app compatibility) and gain iOS 8.4.1 (for speed).

Cons of CoolBooter:

• Requires a Jailbreak.
• Takes up significant storage space (you share storage between two OSs).

Important notes

• No SHSH blobs needed — this uses live OTA signing.
• You lose all data on the iPad (fresh install of 8.4.1).
• Not all apps from 2025 support iOS 8 — many require iOS 10+.
• This method may stop working if Apple ever stops signing iOS 6 OTA for iPad 2.

Major pitfalls and incompatibilities

• SHSH blobs: most users do not have them saved; they must have been saved while Apple was signing 8.4.1.
• SEP (Secure Enclave Processor) and baseband mismatches can prevent boot even if restore completes.
• iCloud/backups: backups made on iOS 9.3.5 may be incompatible with iOS 8.4.1.
• App compatibility: many App Store apps no longer support iOS 8; updates may be impossible to install.
• Security: older iOS has unpatched vulnerabilities.
• Lack of official support from Apple.

The Problem: iOS 9 on iPad 2

The iPad 2’s A5 chip (512MB RAM) was never designed for iOS 9. Users report:

• Laggy UI: Stuttering when opening Control Center or Notification Center.
• Slow app launch: 5-10 seconds to open Settings or Safari.
• Keyboard lag: Typing is a frustrating, delayed experience.
• Crashes: Safari tabs constantly reload due to RAM pressure.
