Actually I tried out this in SM8150 MTP and it works fine for me,

"fastboot set_active a; fastboot set_active b; fastboot set_active a; 
fastboot oem select-display-panel none; fastboot reboot bootloader; 
fastboot boot boot-sm8150.img"

Also I need to switch slots everytime like above, otherwise I always see 
some error
while loading the boot image.

Thanks,
Sai
