How to Install

(Not meant for beginner - neither this installation guide nor the ROM itself.)

1. Backup your phone.
2. Ddownload the zip file from the Assets section below
3. Unlock the bootloader; follow this guide https://forum.xda-developers.com/zenfone-3/how-to/zenfone-3-max-zc553kl-bootloader-unlock-t3691837
4. Get TWRP here https://mega.nz/#F!ZtMT0KxI!ObnACk_mxnPCbPHCVu_G8Q (this is the same place you get the bootloader unlock file in the previous step)
5. In fastboot mode, do fastboot format userdata
6. Flash TWRP using fastboot.
7. Reboot to TWRP, wipe everything.
8. adb sideload the zip. Or adb push and install.

What's working

• OS boots.
• Apps work (except those that require specific hardware features that doesn't work yet).
• Wi-Fi works.
• USB (MTP, ADB, Tethering,...) works.
• Camera works.
• Sensors (Gyro, Light, etc.) work.
• Flashlight works.
• Vibration works.
• Audio works (sound feels a bit delayed but maybe that's just me).
• GPS works.

What's not working

• Bluetooth is very buggy.
• FM Radio is not working.
• Screen Recording is not working (resulting videos full of encoding artifacts).

• Probably many more things. You tell me.

Notes

• I'm not sure if phone calls and other RIL features (4G, 3G, etc) work. Haven't tested.
• I removed the device checking code from the ZIP so it can work with the older version of TWRP. Make sure you only use this for model X00D (ZC553KL).
