Samsung Galaxy A9 Pro (2016) (model SM-A9100/A910F) is an older device that has a limited but dedicated custom ROM community. While it is no longer officially supported by Samsung, you can find projects that keep it updated with newer versions of Android. Popular Custom ROMs for Samsung A9 Pro
Developer Tools
1. LineageOS (The Daily Driver Choice)
If stability is your religion, LineageOS is the answer. Most versions for the A9 Pro are unofficial but highly stable. It offers a pure Android experience with just enough customization to make the phone feel personal.
The Solution: You must install a port of the Google Camera (GCam). Communities on XDA Developers have specific XML config files for the A9 Pro that unlock features like HDR+ and Night Sight, making the camera outperform the original stock software in low-light conditions.
You lose Samsung Pay and slightly degrade the camera, but you gain privacy, speed, and compatibility with modern apps.
Unlock Bootloader: Go to Developer Options > Enable OEM Unlocking.
Install TWRP: You need a custom recovery. Search for twrp_a9pro.tar and flash it via Odin (PC required).
Backup EFS: Before doing ANYTHING, backup your IMEI/EFS folder in TWRP. If you lose this, your phone is a paperweight.
Wipe: Dalvik, System, Data, Cache. (Do not wipe Internal Storage yet).
Flash: Copy your chosen ROM + Gapps (if needed) to the SD card, then flash via TWRP.
Format Data:Crucial step. Go to Wipe > Format Data > type "yes".
3. Project Elixir (Android 13) – The Modern Dream
Status: Beta/Unstable for A9 Pro.
Why choose it: Brings Pixel UI and Android 13 features to this old hardware.
Bugs: Camera crashes occasionally. Hotspot sometimes fails. Not recommended for non-tech-savvy users.
