How to Register Your Serial Number & ECID Free for iCloud Bypass on iUnlock.Cloud

Device registration on iUnlock.Cloud is 100% free with instant server activation. In this official guide, learn whether you need to register your device Serial Number (for iUnlock AIO Tool) or Device ECID (for iUnlock Ramdisk Pro), how to locate these identifiers, and how to start your free untethered iCloud bypass immediately.

Why Is Free Device Registration Required?

When you run iUnlock Ramdisk Pro or iUnlock AIO Tool on Windows 10/11, the software communicates with our cloud server to verify that the connected device is authorized. Registration performs the following critical tasks:

• Generates an Instant Activation Token: Links your device hardware identifier (ECID or Serial) to our activation server.
• Unlocks All Pro Features: Enables One-Click Hello Bypass (No SN Change), usbliter8 BootROM exploit, MDM bypass, Passcode activation with Signal, and Purple mode.
• Zero Cost & Bot Protection: Keeps all tools 100% free while preventing spam and unauthorized server abuse.

Step 1: Determine Which Tool & Identifier You Need

Choose your tool and required identifier based on your iPhone/iPad model and installed iOS version:

Step 2: How to Find Your Serial Number or ECID

A. Finding Your Serial Number (For AIO Tool)

• From the Hello Setup Screen: Tap the small (i) icon in the lower-right corner of the setup screen to display your device Serial Number.
• From Settings: Navigate to Settings > General > About and long-press the Serial Number row to copy it.
• Via 3uTools / iTunes: Connect your device with a lightning/USB-C cable to your PC. The Serial Number is shown on the primary device summary panel.

B. Finding Your Device ECID (For Ramdisk Pro)

• Via 3uTools (Recommended): Connect your iPhone or iPad to 3uTools in normal, Recovery, or DFU mode. Look for the ECID field and double-click to copy the HEX string (e.g. 0x0000810100123456).
• Via Ramdisk Pro DFU Helper: Put your device into DFU mode using the interactive countdown in iUnlock Ramdisk Pro. The software detects and logs your device ECID directly into the operations console.
• Both HEX format (starting with 0x) and Decimal numbers are automatically validated by our registration portal.
