To fix an MT6765 device, you cannot use a generic database; it . These files are usually extracted directly from the official stock ROM (firmware) package of your specific phone model (e.g., Xiaomi Redmi 9C, Oppo A15, Samsung A12). Inside a standard MT6765 Repack archive, you will find:
MediaTek devices utilize specialized partitions and system files to manage hardware-level configurations, specifically regarding cellular connectivity and radio frequencies.
- Your original NVRAM is unique to your device. Create multiple backups in safe locations.
def repack_nvram(file_dir, out_bin, partition_size): # Build file table (simplified) file_table = [] offset = 0x400 # header + table area nvram+database+file+mt6765+download+repack
- In Maui META, navigate to "Change NVRAM Database File" and browse to your BPLGUInfo file.
Navigate to the firmware folder. Look for a subfolder named database , md_db , or simply check the main image directory.
"You're a wizard," the journalist whispered. To fix an MT6765 device, you cannot use
The MT6765 stores critical identifiers and calibration data across four interdependent partitions ( nvram , nvdata , protect1/2 ). Repacking these manually requires a deep understanding of MTK’s LID structure, sqlite databases inside nvdata , and proper checksum handling.
The NVdata partition is closely related to NVRAM. It contains configuration settings that the system uses at runtime, including network‑related parameters and device‑specific calibration values. Tampering with NVdata “without the right knowledge or authorization could result in catastrophic consequences, including IMEI or may be permanent loss of device”.

Problems like an invalid IMEI, a missing baseband, the "NVRAM Warning: Err = 0x10" Wi-Fi error, or a total loss of cellular signal usually point back to a corrupted NVRAM partition.
