I have a verizon S5 G900V. First it was marshmallow. i wanted to root it and unlocked bootloader. i got back lollipop and rooted, then unlocked bootloader with the help of this forum. After that I installed twrp recovery and flashed a marshmallow rooted rom. Everything just worked fine without one, my bootscreen show "Kernel not seandroid enforced" and a custom padlock icon. I tried to install root triangle away and reset flash counter. But it didn't work. If anyone know how to get rid of this problem, please share. I search a lot, but didn't find. (sorry for my bad English)
