NVRAM, or Non-Volatile Random Access Memory, is a type of memory that retains its data even when the power is turned off. Unlike volatile memory (such as RAM), NVRAM doesn't require a constant power supply to keep its data. This characteristic makes NVRAM extremely useful for storing configuration settings, calibration data, and other small pieces of information that are crucial for the device's operation.
In mobile devices, NVRAM is often used to store parameters related to wireless connectivity, such as Wi-Fi and Bluetooth MAC addresses, IMEI (International Mobile Equipment Identity) numbers, and other configuration settings. This data is essential for the device to communicate properly with cellular networks and other devices.

Use SP Flash Tool → Read Back entire nvram + nvdata + protect1.
The keyword nvram+database+file+mt6765+download+repack represents a complete repair ecosystem. You cannot just download a file and flash it; you must:
By following this guide, you turn a dead, unusable MT6765 phone into a fully functional device with valid IMEI and signal. Keep your driver’s updated, always backup the original NVRAM before any flash, and never trust a generic NVRAM file without repacking it for your specific build number.
nvdata contains dynamic NVRAM databases in sqlite format.
Examples:
If you modify IMEI directly in nvram.bin but ignore nvdata, the phone will revert on boot.
Procedure for database repacking:
| Error | Likely Cause | Fix |
|-------|--------------|-----|
| S_BROM_CMD_STARTCMD_FAIL | Driver conflict | Reinstall MTK USB drivers; disable signature enforcement |
| Status: Securely Verifying NVRAM Failed | Checksum mismatch | Recalculate checksum with MTK Checksum tool |
| After flash: Serial number changed | Repacked database contained another phone’s SN | Hex-edit /nvdata partition or use echo 'AT+EGMR=1,7,"YOUR_IMEI"' via engineering mode |
| Wi-Fi still shows "MAC unavailable" | NVRAM database missing Wi-Fi calibration | Extract wlan_mt6765.cfg from stock and push via ADB to /data/nvram/APCFG/APRDEB/ |
