95 MBupdated 2026-08-13 ★ 4.4Pre-activatedMobile

4uKey unlocks iOS devices with a forgotten passcode, a disabled screen or a second-hand lock: it downloads the matching firmware, puts the phone into recovery and reinstalls the system cleanly.

The suite also handles Apple ID removal without a password, Screen Time passcode recovery, MDM profile bypass and remote-device management profiles on modern iOS builds. The provided build runs fully pre-activated with no per-device limits.
