Is there a pre-rooted 0.182 stock ftf from available?

I didn't like my T2 ultra until 5.1.1 (19.4.A.0.182) stock rom came along...it gave the buggy phone a new lease.

I like to root it via flashtoo ftf file. Does anyone has one to share? Also pls advise the steps...do I need to unlock bootloader first? Do I need to install recovery?

I wanted to root to remove bloatwares and use app2sd to install apps.

Thanks!
