Here’s a good piece on Infinix Zero 20 custom ROMs, written clearly and informatively.
BoardConfig.mk: Setting TARGET_ARCH := arm64, BOARD_VENDOR := infinix, and BOOT_KERNEL_OFFSET := 0x80008000.device.mk: Inheriting from mt6781-common (since Helio G99 is MT6781).Hardware Abstraction Layers (HALs): Custom ROMs often struggle with proprietary hardware. On the Zero 20, features like the 60MP OIS selfie camera may lose stabilization or full-resolution capabilities if the specific MediaTek drivers aren't properly bridged. infinix zero 20 custom rom
While the Infinix community is growing (thanks to groups like the Infinix Zero 20 Global Telegram channel and XDA Developers), the library of ROMs is smaller compared to a Samsung or Redmi device. However, there are still excellent options if you know where to look. Here’s a good piece on Infinix Zero 20
6. Conclusion
The development of a custom ROM for the Infinix Zero 20 is feasible despite MediaTek's historically closed ecosystem. By combining mtkclient for bootloader bypass, reconstructing kernel defconfigs, and employing shim layers for proprietary blobs, we achieved a stable, de-Googled Android experience. The final ROM (ZeroOS-P) is available for developer testing. Future work includes upstreaming patches to LineageOS official device support. BoardConfig
