Execute the build with make -jX (where X is the number of CPU threads).

GSI Alternative: If a device-specific ROM is unavailable, you can flash a Generic System Image (GSI), which is designed to work across different hardware using the Project Treble framework. 4. Available ROM Options

1. The Hard Truth: Vivo is NOT Custom-ROM-Friendly

Before flashing, understand the landscape:

• No official bootloader unlock – Vivo does not provide unlock tools like Xiaomi (Mi Unlock) or OnePlus.
• Mediatek Helio P60 (MT6771) – This is actually a good thing for modding. MediaTek devices often have leaks, SP Flash Tool support, and bypasses for bootloader locks.
• No Treble love – The V9 shipped with Android 8.1, but Project Treble support is partial at best. Generic System Images (GSIs) might boot, but with broken RIL, sensors, or camera.

👉 Conclusion: This is not a “download TWRP and flash LineageOS” device. It’s a hacker’s project requiring low-level tricks.
