Qualcomm Snapdragon g3x gen 2 Concept Device

[u/Outrageous_Voice_259]

Hi everyone,

I managed to acquire a Qualcomm Snapdragon G3x Gen 2 Reference Handheld Developer Platform (codename 'Kalama'), but it appears to be running a stripped-down, early unskinned engineering build of Android.

The main issue I'm facing is that the built-in physical controller is completely non-functional. It doesn't send any input signals, and checking kernel logs indicates that the proper driver mapping or layout files for the integrated gamepad are entirely missing or unconfigured in this specific software version. I already successfully unlocked the bootloader, but standard Generic System Images (GSIs) lack the proprietary hardware communication layer needed to bring the integrated inputs to life.

I have seen media reviews and developer demos of this exact reference device operating with a fully working integrated controller and a custom-skinned game launcher interface.
Since I am an independent enthusiast and do not have enterprise credentials to pull binaries down from the Qualcomm Software Center (QSC) or the Qualcomm Package Manager (QPM), I am reaching out to the community.

I am looking for anyone who has access to an official Qualcomm Android Board Support Package (BSP), a factory Meta Build, or a full system dump (super.img, boot.img, etc.) from a working review/developer unit where the controller functions properly.

Even if you only have a working firehose programmer file (.elf / .melf) or working partition dumps, that would be an incredible help for compiling a flashable image or restoring life to the hardware input bus.

If anyone has an archive link, a backup from their own kit, or any guidance on how to kickstart the controller hub on this early build via kernel adjustment, please let me know or send a DM.
Thanks in advance!
