What is an NVRAM File?

NVRAM (Non-Volatile Random Access Memory) is a dedicated partition on your phone’s chip that stores critical device-specific data, including:

• IMEI numbers (both SIM slots)
• Wi-Fi MAC address
• Bluetooth address
• Calibration data for radio, Wi-Fi, and Bluetooth.

Unlike the system (ROM), this data survives factory resets but can be erased by an improper flash, selecting “Format All + Download” in SP Flash Tool, or flashing a full firmware without a backup.
