Irrelevant question - What software do y'all use to make these modified hyperos rom


Oh
Plenty. Some were repurposed from AOSP, and some were custom-made.
If you think we use some kind of "ROM cooker" then you'd be wrong. We're not amateurs.
I'm new to making roms my friend told me to use crb android kitchen tool before I purchase the software I wanted to ask from professionals. Thank you for taking your time to reply.
