I used to bypass redmi note 3 kenzo/kate using modified emmc_appsboot.mbn. After that i can unlock bootloader and install custom recovery such as twrp.
But seems now i can’t do dit using newest MIUI. It gave a bootloop and after that phone just seems to blank and went to port 900E in device manager
So i have to reverted back to original emmc_appsboot.mbn, it start when i flash it using mi flash2015.10.28.0 it gave error message “rpplypatch sector num_disk_sector-1” So i change using mi flash 2016.12.22.0, it doesnt gave error message. But still i’, stuck in infitive botloop.
So the solution is to flash the original emmc_appsboot.mbn using fastboot :
fastboot flash aboot emmc_appsboot.mbn
fastboot flash abootbak emmc_appsboot.mbn
You can download stock here it is for Redmi Note 3 Lolipop MIUI 7
