Hello guys,

Can anyone help me on my Samsung S5G900i? I rooted my s5 before but ever since my supersu has stopped working and it keeps asking me to update the binary, but it fails. I then tried to unroot it fully on supersu, but it failed as well, how do i unroot my s5 if i can't unroot it from my mobile device? Do i need my computer to do it? Also, does having lollipop cause more errors when using apps that need root? Some apps need permission but my supersu dosent grant it when it prompted me to accept it which i do grant but it still denied, also if having lollipop is the issue then can you please help me on how to downgrade it?

THANKS
