Disclaimer: Repairing or rewriting IMEI numbers is illegal in many jurisdictions if done to clone another device or obscure a device's identity. The following guide is provided for educational purposes only and for legitimate repair purposes (restoring a device to its original factory state) by qualified technicians. Ensure you have the original IMEI labels from the device box or battery compartment before proceeding.

Prerequisites: What You Need Before Starting

Before attempting an IMEI repair, ensure you have the following prepared:

  • A Windows PC: These tools are generally designed for Windows 7, 8, or 10 (32-bit or 64-bit).
  • RDA USB Drivers: Without the correct drivers, the PC will not detect the phone when it is connected in Flash/Download mode.
  • Original USB Cable: Ensure the cable is not damaged to prevent interruptions during the writing process.
  • Valid IMEI Numbers: You need the original IMEI numbers of the device (usually found on the box or under the battery). Note: Changing IMEI to a different number is illegal in many jurisdictions; always write the original number.

4. Typical Workflows

  1. Put device into service/diagnostic mode (USB, TestPoint, or key-combo).
  2. Connect via appropriate driver; the tool detects chipset and NV layout.
  3. Backup current NV/EEPROM/IMEI to local file.
  4. Validate target IMEI format (15 digits, Luhn check).
  5. Write IMEI and related NV parameters.
  6. Reboot device and verify IMEI via dialer/field test or AT command (AT+CGSN, AT+EGMR, etc.).
  7. Restore original NV if issues occur.

High-level overview of how it works

  1. Connect phone to PC via USB (sometimes via serial or test points for deep-level access).
  2. Put device into a diagnostic or boot mode recognized by the tool (e.g., ADB, emergency download, diagnostic, or BOOTROM modes specific to Coolsand/RDA).
  3. The tool communicates with the phone’s bootloader/modem to read NV items (IMEI, RF calibration data, network settings).
  4. If NV is corrupted, the tool writes the correct IMEI/NV backups or regenerated NV data to the device.
  5. Reboot and verify via phone settings or by checking network registration.

Commonly encountered modes & connection methods

  • VCOM/USB serial drivers: Many Coolsand devices present a USB serial or VCOM interface in diagnostic/download mode.
  • Emergency/Download mode: A specific boot state (key combinations or test points).
  • ADB/fastboot (on some Android variants) for higher-level access.
  • UART/test-point using a serial cable for unresponsive devices.
