Equip your firmware-preparation bench with the official 12-month license activation for Cerberus Tool Box on GrandUnlock. Designed specifically for mobile repair technicians, refurbishment facilities, and firmware modification specialists, Cerberus Tool Box is a dedicated offline firmware-preparation workspace built to construct custom unmanaged ROMs and patch raw partition images before writing them to target devices.

- License Validity: 12 Months (1 Full Year / 365 Days) of continuous software runtime and utility updates.
- Specialized Firmware Workspaces:
  * No-MDM ROM Maker: Build customized, clean, unmanaged stock-based firmware packages to strip persistent corporate, PayJoy, and regional MDM enrollment configurations prior to flashing.
  * Partition Patcher Suite: Direct file-level modification workspace containing specialized patch algorithms for individual partition images (Super, Boot, Recovery, Proinfo, Prodnv, EFS, and NVRAM).
- Advanced Hardware & Security Patch Utilities:
  * Brand-Specific Patchers: Dedicated algorithmic patchers tailored for Transsion (TECNO, Infinix, itel), Samsung, Xiaomi, and Vivo devices.
  * Vivo RPMB IMEI Patcher: Direct utility to analyze and rewrite dual IMEI parameters inside supported Vivo RPMB dump files.
  * PayJoy & Cloud Lock Removal: Modify system partitions to eliminate cloud-based device financing and administrator supervision hooks cleanly.
- Standalone File Processing: Generate, modify, and unpack firmware images locally on your workstation without requiring a device to be actively connected during ROM preparation.
- 100% Digital Activation: License is linked directly to your registered user account email—no physical box, dongle, or smartcard required.

Important Technical Guidelines & Policies:
1. Workstation & PC Binding:
   - Cerberus Tool Box operates via secure cloud account authentication.
   - The license is authorized for single-PC usage per active session. Unauthorized session sharing or rapid multi-location logins may result in server security locks.
2. Account Registration:
   - Ensure you have registered your account inside the official Cerberus client or web portal before ordering.
   - Submit your exact registered Email Address used during account registration.
3. Operating System & Security Configuration:
   - Compatible with 64-bit Windows 10 and Windows 11.
   - Run the software setup as Administrator. Low-level partition modifying tools can generate false-positive alerts in standard antivirus software; add the installation folder to your security exclusions.
4. Non-Refundable Digital Delivery:
   - Digital activations are processed directly on the official server database and cannot be canceled, transferred, or refunded once completed.

How to Order & Activate:
1. Download the latest Cerberus Tool Box software setup and register an account using your active Email Address.
2. Enter your registered Email Address into the required field on GrandUnlock and complete checkout.
3. Once your order status changes to "Completed", open Cerberus Tool Box, log in with your account credentials, and begin building custom ROMs and patching partition files immediately.
