Sony Encrypted ID Copy

Overview

Sony LCD panel logic boards typically contain a set of encrypted screen identification data, used for authentication and parameter matching between the panel and the mainboard. When replacing a screen or logic board, an encrypted ID mismatch may cause display anomalies, backlight failure, or the system failing to recognize the panel.

VolToolV2 can read and copy this encrypted ID data, store it in the tool's external Flash, and later write it to other logic boards or dedicated encryption daughter boards — enabling seamless screen replacement.

Use Cases

  • Replacement logic board needs to match the original Sony panel
  • Migrating an original Sony panel to a different device
  • Pre-programming encrypted IDs for inventory stocking

Operation

Read Encrypted ID

  1. Select Sony ID Copy from the main menu
  2. Choose Read ID
  3. Connect the Sony original logic board via the appropriate interface
  4. The tool automatically reads the encrypted data and displays verification info
  5. Data is automatically saved to the tool's Flash storage upon completion

Write Encrypted ID

  1. Connect the target logic board or encryption daughter board
  2. Select Write ID
  3. Choose a previously saved encrypted ID from the tool
  4. Confirm the write operation
  5. Automatic verification follows

Managing Stored IDs

The tool supports storing multiple encrypted ID records with the following management operations:

  • View List: Display all saved ID records
  • Delete: Remove unwanted ID data
  • Rename: Add descriptive labels for easy identification
  • Export/Import: Transfer IDs to/from a computer via the upgrade port

Precautions

  • Ensure correct and stable connections during read/write operations
  • Verify target logic board compatibility before writing
  • Back up the target board's original data before writing when possible
