I am trying to boot Android into a custom recovery(TWRP). I rebooted the Android device holding the Volume Down + Power keys but it doesn't work and shows a weird screen with yellow colour palette on it and it can't be turned on. I tried following this How To Boot Android Into A Custom Recovery (TWRP, CWM, Philz Touch) but it still doesn't boot. Any help?
I'm assuming you're using a Samsung model. Its volume up + home button + power .
On My Android Device It Is Volume Up + Power Or On Samsung It Is Volume Up + Home + Power.
