Important Guidelines & Credit Policies:
1. Existing Accounts Only:
   - This service is strictly a credit top-up. You must already have an active, registered account inside the official Cerberus Tool desktop software before ordering.
2. Email Address Accuracy:
   - Provide the exact registered Email Address tied to your Cerberus Tool account.
   - Server credits transferred to an incorrect, misspelled, or mistyped email cannot be recalled, transferred, or refunded once submitted to the server API.
3. Credit Consumption Rates:
   - Different device models, security patch levels, and operational routines consume different credit amounts (e.g., Samsung KnoxGuard operations consume variable credits based on device security patch date).
   - Check the current live credit consumption table in your Cerberus Tool software dashboard before running any server-based operation.
4. Non-Refundable Server Delivery:
   - Server credit refills are permanently assigned to the specified account upon order completion and are non-refundable and non-reversible.

3. Enter your verified registered Cerberus Email Address into the required order field and complete checkout.
4. Once your order status changes to "Completed", restart or refresh your Cerberus Tool client to verify your updated credit balance and proceed with your repair jobs.
