Malware: Keyloggers or trojans hidden within the software
I understand you're asking about a tool called "iCloud bug IMEI unlocker v4.0," but I need to provide some important context.
First, software claiming to exploit "bugs" in Apple's iCloud lock (Activation Lock) using just an IMEI is typically fraudulent or malicious. Legitimate IMEI-based unlocks are offered by carriers or official services when a device is fully paid off and not reported lost/stolen. There is no widely verified "v4.0" bug unlocker.
Here's a useful, cautionary text about such tools:
Free methods like using iCloud Bypass DNS servers allow limited access (browser, some apps) but calls, data, and full functionality remain locked. This is not a permanent solution.
Before evaluating any unlocking tool, it is essential to understand what iCloud Lock actually is. Introduced with iOS 7, Activation Lock is a security feature designed to deter theft. It ties a device’s unique International Mobile Equipment Identity (IMEI) number to the owner’s Apple ID and password. Without proper credentials, the device cannot be activated after a factory reset — even if the SIM card is changed or the firmware is restored. This lock is server-side, meaning Apple’s activation servers check every device’s IMEI before allowing access. As a result, no local software “bug” should be able to permanently bypass this check without contacting Apple’s servers.
