[Q] Best way to unroot and get stock Lollipop?

[magus57]

I've currently got a rooted Z1C with a custom ROM. I have my TA backup as well. I'd like to go to stock Lollipop as painlessly as possible.

I'm assuming I'd have to do something of the following: clear system/data, install stock Kitkat ROM, restore TA, OTA to Lollipop. Is that right?

I think if You flash a ftf, it also wipes Your system and data. But to be on safe side, You can wipe those and follow the procedure You mentioned.
