Miui 8 - Oppo F1s

Installing MIUI 8 on Oppo F1s requires a custom recovery (TWRP) and a compatible MIUI 8 ROM. Several developers have created unofficial MIUI 8 ports for Oppo F1s, which are available for download. These ports are based on the Xiaomi.eu MIUI 8 builds, which are compatible with a wide range of devices.
