I want to do this because I want to use a external dual sim.
Can it work well with basic xz1 dual compact framware?

These dual SIM adapters work by switching between SIM cards every minute or other interval. It allows you to have both SIM cards "online" without need to replace them in the slor but in reality only one is connected to the network at the moment. You do not have to flash or install any software to make these adapters work so there is no need to flash XZ1 Dual firmware. And on the attached image I can see not the dual SIM adapter but only one SIM slot on a flex cable allowing to replace the SIM card without opening the phone's SIM card slot.
Any dual SIM adapter which is connected just to the phone's SIM slot is a workaround which has drawbacks and limitations I mentioned earlier.for example ,I want to control sim 1 runs the internet and sim2 for calling .The problem is that xz1comapt original operating system does not support dual SIM, so I want to flash xz1comapt by XZ1 firmware dual for more control over the dual sim
Unfortunately, there is no way to make it work on a single SIM phone. It is both software (lack of this menu) and hardware (no way to have both SIM cards online at the same time) limitation.
