Need help identifying and flashing S24 Ultra clone.

Wait 5 sec.

"Hi everyone, I have a clone of a Samsung S24 Ultra, and I want to replace the original firmware because it feels really slow and some apps don't work. CPU-Z says it has a MediaTek processor, ten cores, running at 2.3 gigahertz, and it shows a 'Custom build version' of 'alps-mp-q0.mp1-V196.1'. Does anybody know where I could find compatible firmware or maybe a generic ROM that might work?"
