This is a detailed guide for finding and installing a custom ROM on the Oppo A37fw (codenamed a37f).

⚠️ Critical Warning Before You Start

  • Oppo’s bootloader is notoriously locked. The A37fw (MediaTek variant) is slightly easier than Snapdragon Oppos, but still difficult. Most custom ROMs for this device exist only if you have already unlocked the bootloader using an exploit (like MTK Client or hacked bootloader unlock tools).
  • If your bootloader is not unlocked, you cannot install any custom ROM.
  • This device is old (2016) – development was always limited. Most ROMs are Android 7.1.2 (Nougat) or Android 8.1 (Oreo), not newer Android versions.
  • You risk hard brick if you flash the wrong file. Proceed only if you understand these risks.

Common Issues and Fixes for Oppo A37fw Custom ROMs

Even with stable ROMs, you might encounter glitches. Here’s the troubleshooting guide.

| Problem | Likely Cause | Solution | |--------|--------------|----------| | Bootloop after flashing | Wrong ROM version or incompatible GApps | Boot to TWRP, wipe data, reflash ROM only. | | Camera not working | Missing vendor blob | Flash a camera patch zip from the ROM’s thread. | | SIM card not detected | RIL firmware mismatch | Reflash stock modem via fastboot: fastboot flash modem NON-HLOS.bin | | WiFi drops frequently | Power saving tweaks | In developer options, disable “WiFi Scan Throttling”. | | Battery drains fast | Google Play Services | Install a wakelock blocker like Servicely. |

Pro Tip: Always read the last 10 pages of the XDA forum thread for the ROM you choose. Developers often post hotfixes there.

Recommendation (concrete)

  • If you want stability and fewer surprises: try a well-reviewed LineageOS or widely used AOSP build for A37fw (search XDA).
  • If you want the latest Android and don’t mind debugging: choose a community build with active maintainers and frequent updates.

  • In TWRP, go to Wipe > Advanced Wipe.
  • Select: Dalvik / ART Cache, System, Data, and Cache.
  • Do not wipe Internal Storage (unless you have the ROM on an SD card).

  • Transfer your downloaded Oppo A37fw custom rom.zip and GApps.zip (use Nano or Pico for ARM64 > Android version).
  • Tap Install, select the ROM zip, swipe to flash.
  • Immediately flash GApps before rebooting.
  • (Optional) Flash Magisk zip for root access.

Step 5: Reboot and Patience
