Nova 5t Custom Rom =link=

I notice you've asked to "develop a feature" for a Nova 5T custom ROM, but you haven't specified which feature you want.

The Huawei Nova 5T (codenamed Yale / Yal — actually Kirin 980, not Snapdragon) is a bit unique because it uses a HiSilicon Kirin 980 chipset. Custom ROM development for Kirin devices is significantly harder than for Snapdragon due to lack of open-source GPU/HWcomposer drivers and no proper Project Treble GSI support for the P-Series partitioning.

To help you effectively, please clarify:

1. Which feature are you requesting?
Examples:

• Camera → Full 48MP + wide + macro + depth working (currently broken in most Kirin custom ROMs)
• Display → High brightness mode (HBM), DC dimming toggle
• Audio → HiFi DAC routing, aptX Adaptive / LDAC tweaks
• Performance → EAS scheduler tuning for Kirin 980, CPU boost control
• Battery → Smart charge limit (stop at 80%)
• Connectivity → VoLTE/VoWiFi icon + toggle for unsupported carriers
• UI → MIUI-style control center or OOS-like gesture customization

2. Which base ROM?

• LineageOS 20/21 (Android 13/14)
• DerpFest
• crDroid
• AOSP GSIs (phhusson)
• EMUI-based custom (e.g., KangOS)

3. What's your role?

• End user wanting a pre-built feature
• ROM developer needing patches or code
• Tester needing instructions

If you just want a generic example of a custom ROM feature for Nova 5T:

4.3 Example: LineageOS 20 GSI

A 2025 XDA forum test reported:

• Boot success rate: 70% (often requires AVB disable)
• Daily driver stability: No (random reboots every 2-3 hours)
• Battery life: 30% worse than stock

4. DerpFest (Android 14)

• Status: Beta
• Best for: Early adopters who want Android 14’s predictive back gestures and ultra battery saver.
• Warning: Camera app crashes occasionally. Use Open Camera as a workaround.

Final Thoughts

The Nova 5T custom ROM scene is alive thanks to a small group of dedicated developers on Telegram. While not as easy as a Pixel, the device is a sleeper hit. With a fresh ROM, the Kirin 980 still benches competitively with a Snapdragon 778G.

Go ahead. Unlock that bootloader. Your Nova 5T deserves a second life.

Before attempting to install a custom ROM, you must navigate the bootloader hurdle. Official methods are gone, so you will need:

Bootloader Unlock: Tools like PotatoNV can sometimes unlock Kirin 980 devices by using a hardware "testpoint" method, which involves physically opening the device to short specific pins.

Third-Party Services: If hardware modding isn't for you, some users still utilize paid third-party services like DC-Unlocker to obtain codes.
