Unlike Xiaomi or OnePlus devices, the Oppo A11K does not have an official presence on platforms like LineageOS or Pixel Experience. However, thanks to independent developers on XDA Forums, 4PDA, and Telegram groups, there are several stable and semi-stable custom ROMs available.
Most of these ROMs are based on Android 10 (Go edition) or Android 11 (Lightweight variants) due to the device’s modest hardware (MediaTek Helio P35, 2GB RAM, 32GB storage).
Here are the active download links for GSIs compatible with OPPO A11K. Use these at your own risk.
