Do not flash the twrp.img , just boot in twrp through fastboot mode ..
So the steps are ..
Hold vol down and power on to enter fastboot mode ..
Open a cmd and type ..
fastboot devices ( cmd will recognize the device )..
fastboot boot TWRP_cmi.img ( phone will enter to twrp )..
If internal space is encrypted do a format data , go to WIPE , choose right box which says format data , type yes and hit enter ..
Then go back to main menu of twrp and choose REBOOT, then hit Bootloader ( phone will enter fastboot mode ) ..
fastboot boot TWRP_cmi.img ( phone will enter again twrp ) ..
Now twrp probably will be encrypted and you can copy zip rom file in your sd card ..
Choose Wipe and swipe right to do a factory reset ..
After installation finished , choose left button and swipe to wipe cache and dalvik ..
Reboot system , Done !!
