If the device belongs to you but you simply forgot your Apple Account credentials, use Apple’s native account recovery tools. Go to apple.com.
Dr.Fone provides a more user-friendly interface, operating as an all-in-one suite to remove activation locks.
Before you begin, ensure you have the following:

If you are the original owner of the device, Apple will remove the Activation Lock for you.
While the concept worked over a decade ago on older hardware, it is technically impossible on modern iOS devices. To understand why, you must understand how Apple processes device activation: 1. Server-Side Verification
Apple’s servers check the status of that specific hardware. If the servers show that "Find My" is active, the server sends a command back to the device to lock the screen and demand the Apple ID credentials. Because this check happens on Apple's secure servers, modifying the local firmware (the IPSW file) cannot permanently change your device's status in Apple's database. 2. Cryptographic SHSh2 Blobs and Signing If the device belongs to you but you
This method is not recommended .
If you bought a locked device secondhand:
The iCloud Activation Lock does not live inside the firmware of your iPhone. It is a server-side security mechanism. When an iOS device undergoes initial setup, it sends its unique hardware identifiers (UDID, IMEI, and Serial Number) to Apple’s activation servers. Apple's servers check if the device is linked to an Apple ID. If it is, the server sends a command back to the device to trigger the lock screen. Modifying the local software cannot alter the status stored on Apple's secure servers. 2. Cryptographic Firmware Signing
Here is a general overview of the process, based on common methods described in online tutorials: Before you begin, ensure you have the following:
Modern iPhones (A12 chips and newer, such as iPhone XS through iPhone 17) have hardware-level security that generally prevents the installation of modified firmware unless a specific bootrom exploit exists.
This refers to an IPSW file that has been modified by a third party, usually to include a jailbreak, alter system files, or bypass certain restrictions. In the early days of iOS (such as iOS 3, 4, and 5), custom IPSWs created by tools like PwnageTool or Sn0wbreeze were frequently used to jailbreak devices and preserve baseband versions for network unlocking.
Apple uses a strict firmware signing window. You can only install an IPSW file if Apple is currently "signing" it. During a restore, iTunes/Finder communicates with Apple's servers to get a digital signature (SHSh2 blob) unique to your specific device and that specific iOS version.
: Apple stops "signing" old IPSW files shortly after new updates. iTunes will generally refuse to install a custom IPSW if Apple’s servers do not verify it. 5. Recommendation for Verification
The single best, safest, and most permanent way to remove an Activation Lock is through Apple itself. If you are the rightful owner of the device, Apple will remove the lock for you completely free of charge.
