  1. Corrupted NVRAM (Non-Volatile Random Access Memory): Unlike Qualcomm devices that store IMEI in a dedicated partition (like modemst1/modemst2), Unisoc devices store critical network data (IMEI, MAC address, Bluetooth address) within the NVRAM partition. If this partition gets wiped or corrupted, the IMEI disappears.
  2. Improper Firmware Flashing: Using tools like SPD Upgrade Tool (Research Download) without selecting the correct partition configuration often erases the NVRAM.
  3. Formatting the "Calibration" Partition: Some factory ROMs include a hidden "calibration" file. If you accidentally format the nvdata or prodnv partition, the phone loses its unique identifiers.
  4. Rooting and Xposed Modules: Aggressive system modifications can inadvertently overwrite the NVRAM index.
  5. Hardware Failure (Rare): In some cases, the eMMC chip develops bad sectors, physically damaging the NVRAM area.
