You can flash image files with fastboot.

I don't know the reason. I could not upload zip file into my phone through TWRP recovery.
So eventually I sideloaded stock rom through fastboot.
Which effectively means that I am back to unrooted and no TWRP.
Also, 33R seams to be buggy. Battery performance is still jittery and it can't detect wifi automatically. I need to switch it off and on to make it work again.
So, I want to go back to my earlier backup which was 25R. I need a fool proof process to do so.
Would really appreciate all your help
