Feature proposal — "Asus Fonepad K004 Custom ROM 2021"

Summary

Create a lightweight, stable custom ROM for the Asus Fonepad K004 (Intel Atom Z2420) that modernizes the device while maximizing performance, battery life, and security for 2021-era apps.

2. AOSP 6.0 (Marshmallow) – The Experimental Dream

• Status: Bootable but not daily-driver ready.
• Major issues: Camera crashes, hardware acceleration hiccups, and random reboots when charging.
• Why it mattered: Proved the kernel could be patched for newer Android, but GPU drivers (PowerVR SGX540) were the bottleneck.

Why Bother with a Custom ROM in 2021?

Before we dive into the files, let’s discuss the "why." If your K004 is running stock ASUS firmware, you are facing:

1. The Certificate Apocalypse: SSL security certificates expired years ago. Many websites will show "Connection not secure," and the Play Store struggles to download basic apps.
2. Intel x86 Compatibility: The K004 runs an Intel Atom Z2560 (x86 architecture). Modern Android has moved heavily toward ARM. A good custom ROM patches the x86 libs to run ARM code (via libhoudini), which is broken in the stock OS.
3. Performance: Stock Jelly Bean is bloated with old ASUS apps. A lightweight custom ROM (like LineageOS) strips away the bloat, freeing up RAM.
