The DB file (BPLGU or MDDB) is required for tools like SN writer and Maui Meta to write IMEI, WiFi / Bluetooth address etc to a Mediatek Android device. You'll usually find the DB files in the official firmware. Should you not find the file(s) in the firmware you downloaded, you can easily extract from your device.

Steps to extract BPLGU / MDDB from a Mediatek device

To extract the DB files(s) from a Mediatek Android phone:

Root the phone (you could use Magisk )
Install a root browser like ES Explorer or ROM Toolbox Lite
Navigate to /system/etc/mddb/
Copy BPLGUInfoCustomAppSrcP**** from /system/etc/mddb/ to your device's storage and then to your PC

Important Notice

Should you flash a different firmware after extracting the DB file then you best re-extract the DB when next you wish to use it an a tool else you could run into 'DB inconsistent' error codes
You best extract the DB file only from the phone you wish to work on. Using another device's DB files could give errors in the IMEI write tools
You can also find the DB files in some firmware for your model
