Pixhawk cube orange plus is not support skydroid h12

I am using pixhawk cube orange plus and skydroid h12 with it. skydroid h12 runs on android 8 due to which latest qgc is not working. Old firmware is not available like v1.14.0 or 1.15.0. Please give a solution for it or make some old firmware available

Sounds like a Skydroid issue.

If you want to flash PX4 v1.14 or v1.15 you will have to build it from source.

I am a newbie could you please help me with the firmware i am stuck
