How to play F Phrygian b4 on guitar

Find the root first: F is at fret 1 on the low E string and fret 8 on the A string. The blue notes on the diagram are every F on the neck; the gold ones are the rest of the scale's home chord (♭3, 5, ♭7), the safest notes to land on at the end of a phrase.

Learn it one box at a time. Position 1, the E shape, sits at frets 1–5. Once it's under your fingers, move to position 2 (the D shape) and play the notes the two boxes share, then keep going up the neck. After all five, the scale joins up into one pattern across the whole fretboard.
