Overview

The Oppo A37fw is a 2016 entry-level device (MT6750, 2GB RAM, 16GB storage). Official support ended at Android 5.1 (ColorOS 3.0). Custom ROMs are scarce but exist mainly on Chinese forums (like NeedROM, 4PDA, XDA-Developers — though XDA has limited official threads).

Pros

✅ Extends device life beyond ColorOS 3.0
✅ Debloated, cleaner interface (near-stock Android)
✅ Improved RAM management vs ColorOS (especially on Lineage 14.1)

Preparation — Backup & sanity checks

  1. Backup user data (photos, messages, contacts).
  2. Make a full Nandroid backup in recovery (after installing custom recovery).
  3. Ensure device battery > 60%.
  4. Verify ROM and recovery are explicitly for Oppo A37fw (model code check).
  5. Download checksums and verify file integrity.

Step 1: Unlock the Bootloader

Oppo devices are notoriously difficult to unlock. Unlike Xiaomi or OnePlus, Oppo requires an official unlock code. However, for the A37fw, a workaround exists using fastboot oem unlock.

  1. Enable Developer Options (tap Build Number 7 times).
  2. Enable OEM Unlocking and USB Debugging.
  3. Reboot to Fastboot (Volume Down + Power).
  4. On PC, run: fastboot oem unlock
  5. Confirm on the phone. Your device will wipe and reboot.

1. LineageOS 18.1 (Android 11)

Best for: Stability and daily use

LineageOS is the gold standard. Version 18.1 brings Android 11 to the A37fw with a clean, Pixel-like interface. It includes privacy features like scoped storage and one-time permissions. Performance is smooth, and battery life is excellent.

Step 2: Flash TWRP Recovery

  1. Reboot to fastboot again.
  2. Run: fastboot flash recovery twrp_a37fw.img
  3. After flashing, use: fastboot reboot recovery (do not boot to system yet, or TWRP will be overwritten).
