In 2025, using an OPPO A37m with its original 2016 firmware is a security risk. The last official security patch for this device likely dates to 2017 or 2018, leaving the MT6755’s modem firmware vulnerable to Broadpwn-style exploits. However, the open-source community has created backported with Linux kernel 4.9+ (up from the stock 3.18) and Android Go patches. These third-party firmware images remove OPPO’s bloatware, add gesture controls, and disable the proprietary tad (OPPO’s statistics daemon).
This is the standard software utility used to burn firmware images onto MediaTek motherboards. Use a stable release, such as version 5.x, for older device architectures. Step-by-Step Flashing Procedure

The industry standard for MTK devices.
OPPO locked the A37m's bootloader tightly. Unlike Qualcomm variants where you can use QDLoader EDL mode relatively easily, the MT6755 uses and Preloader mode (Volume Up + Insert USB). The interesting part: OPPO implemented SECCFG anti-rollback and DA (Download Agent) protection in later firmware updates (ColorOS 3.0+). Flashing an older firmware version triggers a " DA mismatch " or " Anti-rollback check fail " in SP Flash Tool. You have to use a custom DA file (e.g., MT6755_Android_scatter.txt with an auth bypass DA) — something most generic guides don't mention.
