What I did!
Bought S5. Rooted with CF autoroot.
On 24.5. a firmware update was available from Samsung.
Installation OTA not possible due to root.
Samsung firmware updated using KIES.
After update root was gone.
Odin and CF autoroot fails now:
<ID:0/003> Firmware update start..
<ID:0/003> NAND Write Start!!
<ID:0/003> FAIL! (Auth)
The button in Odin does not go to yellow as mentioned.
