This post is a short overview about iCloud bypass after iOS 11 release. I will fill up it in the future.
After iOS 11 any hardware bypass doesn’t work on new 64 bit Apple device BUT:
- Old iPads 2, 3, 4 and mini 1 didn’t receive iOS 11. Hardware method works.
- If you have iPad Wi-Fi Only with iCloud lock you can unlock it through editing device SN in the NAND with help of special equipment
What is about already bypassed devices?
Looks like the most time you can update iCloud bypassed iPads by OTA (by Wi-Fi) without problems. But if you restore or erase iCloud bypassed in the future then the device will be locked because of:
iOS 11 is checking UDID for activation. Udid is calculated from serial numbers and Wi-Fi or Bluetooth addresses.
If we convert the cellular to Wi-Fi udid will change. So there is no activation possible.
I don’t recommend updating iCloud bypassed iPads to iOS 11.
