When this data is corrupted, your device cannot authenticate with mobile networks, resulting in an "unknown baseband" or "invalid IMEI" scenario, often triggered by a crash on the logo saying "NVData is corrupted" or "The system has been destroyed". Causes of NVData/NVRAM Corruption on Earth Devices

On MediaTek-powered smartphones, the NV (Non-Volatile) partitions store hardware-specific, unencrypted calibration data critical to device functionality.

Without disconnecting the phone, load your official "earth" factory scatter firmware and flash the full operating system.

: In some cases, after writing the IMEI, you must perform a "Patch Cert" procedure to ensure the network stays active after a reboot. Key Resources Poco c55 or Redmi-12c-earth- NvData NvRam File ...

This method does not require a downloaded NV file. It uses the phone's hidden backup (BPLGU) to regenerate data.
