Restore stock Recovery, Relock to restore install original rom

Htc m8 has been bootload unlocked, TWRP recovery installed, S-on still. I have backup stock rom using TWRP, and I restore the stock rom using TWRP with backup files. When it android, it keep popup alot error message and missed all the soft Nav key.

Now, what's better suggestion beside run RUU for total restore to stock? To run RUU on S-on device, I need to relock and restore stock recovery right??
