Now when i try to deleted cache on bootloader screen all it does is says....If you are trying to download a custom rom press volume up. Or down to cancell. On galaxy s5 with android verson 6.0.1
Welcome to Android Central! It sounds like you booted into Download Mode (aka Odin Mode). This is typically achieved by pressing and holding Power, Home, and Vol Down. To boot into Recovery, you press and hold Power, Home, and Vol Up. https://support.t-mobile.com/docs/DOC-28492
