R7000 tomato upgrade help

Hi guys!

I had sucessful flashed my router 2 months back with tomato firmware. But there has been an upgrade for a while now and I haven't upgraded it. There are two files needed for the flashing - .chk and .trx. The .chk for the initial flash and .trx for the final flash.

Now, for the upgrade to the latest firmware do I need both files to do it? Is the initial .chk file needed?

Do I need to reset my router for the upgrade too? I have put in a lot of settings and if updates comes every few months I can't be resetting everything from scratch again.
