Keep in mind...
DO NOT try to change the included kernel

System is Read-Only (restricts making changes to overlays, system APKs, etc.)

DO NOT USE any other recovery than AlphaDroid recovery which is included.

You MUST format data with given AlphaDroid recovery

YOU MUST CLEAN FLASH IF:
- You are coming from any other ROM or MIUI
- You are coming from previous Android Version

If you face issues like poor RAM management or storage issues, you have not followed the instructions and/or have changed kernel/recovery. STRICTLY follow the instructions provided again before reporting any issues.

Formatting with AlphaDroid Recovery (yes, I mean AlphaDroid Recovery ONLY) is MUST during clean flash
-------------------------------------------
Clean Flash (coming from a different ROM):
Clean flash involves formatting data which means you will be loosing data stored in the internal storage of your device, data in SD Card should not be affected. I will not be responsible for any loss of data.

- Download ROM, Recovery.zip to your computer (click on recovery button for recovery.zip)
- Reboot the device to bootloader (Fastboot Mode)
- Extract Recovery.zip
- Flash the vendor_boot by running fastboot flash vendor_boot <path/to/vendor_boot.img> in terminal
- Flash the boot by running fastboot flash boot <path/to/boot.img> in terminal
Reboot to recovery by running fastboot reboot recovery in terminal
- Go to main menu > Factory reset > Format data/factory reset > Format data > Back to Main menu > Reboot to Recovery
- On your phone [which is in recovery mode], Apply update > Apply from ADB
- Flash the ROM through ADB sideload by running adb sideload <path/to/rom.zip> in terminal
- Download firmware (Version V14.0.9.0.SKGMIXM) from here
- Flash firmware through ADB sideload by running adb sideload <path/to/firmware.zip> in terminal
Reboot and voila!
