Ipad: 2 9.3.5 Icloud Bypass Untethered [better]

Finding a legitimate academic paper specifically titled "iPad 2 iOS 9.3.5 iCloud Bypass Untethered" is difficult because specific consumer exploits are rarely the subject of formal academic literature until years later (usually when the vulnerability is patched and analyzed).

However, the "Untethered" aspect for the iPad 2 on iOS 9.3.5 is a fascinating case study in hardware security failures.

The most interesting and relevant paper/technical analysis regarding this specific device and exploit method is not a standard academic PDF, but rather the technical documentation of the "Duplicate" / "Device" Exploit (formerly checkm8) adapted for the A5 chip.

Here is the most relevant technical breakdown, presented in the format of a research paper analysis, as this is the primary source for how the untethered bypass works on that specific device.

Q: I have an iPad 2 on iOS 6/7/8 – should I update to 9.3.5 first?

A: Yes, but updating normally will trigger iCloud lock. Use Legacy iOS Kit to restore to 9.3.5 without losing bypass ability (complex). Easier: Stay on current OS if possible. Step 4: Restore with Custom IPSW (Automatic)

Summary for your research

If you are writing a report or paper, your thesis should focus on: "The evolution of hardware security bridges: How the lack of a Secure Enclave Processor in the A5 architecture transformed a tethered BootROM exploit (checkm8) into a persistent untethered state on iOS 9.3.5."

Step 4: Restore with Custom IPSW (Automatic)

• Sliver will ask for the stock 9.3.5 IPSW.
• It will patch the activation records and restore the device.
• The iPad will reboot – this takes 5–10 minutes.

Q: Is this truly untethered?

A: Yes – with checkm8-based tools like Sliver, the bypass persists after full power off and on. No computer needed again. Sliver will ask for the stock 9

9. Final Warnings

• Do not use paid remote bypass services that ask for your device serial – many are scams.
• Checkm8 is not a magic bullet – Apple cannot patch it (hardware), but future iOS versions don’t matter for iPad 2.
• If you sell the device, disclose that it’s iCloud-bypassed. The next owner cannot restore it.
• Legal risk: Selling or giving away a bypassed device that isn’t yours can lead to liability.

1. Understanding the Terms

• iPad 2 (Wi-Fi / Cellular): A 2011 device with an A5 chip. iOS 9.3.5 is its final official OS.
• iCloud Lock (Activation Lock): Ties the device to an Apple ID. Without the password, the device is a brick after a restore/update.
• Tethered vs. Untethered:
  • Tethered: Bypass stops working after a reboot; you need a computer to re-activate.
  • Untethered: Bypass persists across reboots without a computer.

For the iPad 2 on 9.3.5, true untethered iCloud bypass is rare and historically required either:

• A server-side exploit (most patched)
• A bootROM exploit (like Blackbird or checkm8) – which the iPad 2 has!
