ZU downgrade query

Dear experts, I bought this phone recently and it came with 5.0.2, 14.5.A.0.270. I have rooted my phone and flashed dual recovery and have TA backup. bootloader is locked.

I want to flash 4.4.4 as I don't like lollipop. Can I just flash C6802_14.2.A.0.290_Customised IN.ftf.

Please help. Thanks.
