The Huawei Y9 Prime custom ROM scene is alive but hidden. It’s not for casual users. Between paid unlocks, Treble quirks, and broken VoLTE, you’re trading stability for freedom.
But for those of us who refuse to e-waste a perfectly good pop-up camera phone? Flashing LineageOS 18.1 and watching that lens slide up with zero Huawei spyware is pure satisfaction.
Just remember: Always keep a full stock firmware backup. On a Kirin device, that’s your lifeline.

Here’s a structured, informative piece about Custom ROMs for the Huawei Y9 Prime (2019) — including model variants, challenges, and recommendations.

| Feature | EMUI 10 (Stock) | LineageOS 18.1 | |---------|----------------|----------------| | Pop-up camera | ✅ Works | ✅ Works (manual init fix) | | Fingerprint | ✅ | ✅ | | Banking apps | ❌ (no updates) | ❌ (SafetyNet) | | Battery life | 6h SOT | 5h SOT | | Security patch | Jan 2022 | June 2024 | | GCam support | No | Partial (no night mode) | Do you have a Y9 Prime running a custom ROM
The trade-off: You gain modern Android + security patches, but lose banking apps unless you root + hide with Magisk + Shamiko + Play Integrity Fix (cat-and-mouse game).
Stability Rating: 8/10 LineageOS is the gold standard. For the Y9 Prime, you will likely use a "GSI" (Generic System Image) version of LineageOS 20.
Security patches are critical. Stock EMUI on the Y9 Prime is stuck on 2021 patches. Custom ROMs like LineageOS or Evolution X provide bi-monthly security updates.
