This ROM packs Oreo features onto the Snapdragon 210. You get picture-in-picture, notification dots, and autofill. However, be warned: Oreo is heavy for the Adreno 304. Expect minor UI stutters. The camera might crash occasionally.

LineageOS is the gold standard for custom ROMs. The 14.1 build for BG2-U01 is incredibly stable. It replaces EMUI with a near-stock Pixel-like interface. All hardware works: Wi-Fi, Bluetooth, GPS, and RIL (Calls/SMS). You get the benefit of modern notification controls and multi-window mode, which stock Lollipop lacked.

Disclaimer: Flashing custom firmware on the BG2-U01 carries a high risk of bricking the device. Unlike phones, the Watch 2 has no reliable "unbrick" tool due to Huawei closing the servers. Proceed only if you have a full backup of the persist partition. Stability Rating: 7/10 Best for: Features lovers

If you are using the Huawei BG2-U01 as a primary phone in 2025, you shouldn't be. The hardware is too old for modern Uber or banking apps. However, as a secondary device—a music player, a GPS tracker, a kid's first phone, or a smart home controller—a custom ROM is a miracle worker.

Specifically, LineageOS 14.1 transforms the BG2-U01 from a laggy museum piece into a snappy, usable Nougat device. You will gain modern emojis, better permission management, and actual security patches (backported by the community). Bugs: Yes, absolutely—with caveats
