Scrambled cube -> Opposite Centers -> FB -> dR Edge Pairing -> Last 4 Centers -> Edge Pairing -> EOPair (+ OLL Parity) -> LXS -> OCLL -> PLL (+ PLL Parity) -> Solved cube


APB4 is a theoretical 4x4 method using the APB 3x3 method.

Opposite Centers

Solve Centers on the L and R layers of the cube.

FB

Solve a 1x3x4 block on dL.

dR Edges

Pair the edges that belong on dR while placing them on dR.

Last 4 Centers

Solve the last 4 centers using the M slice and U layer.

Edge Pairing

Use the M slice to pair all of the remaining edges. 4-2-3 edge pairing works greatly here. And remember to solve the DF and DB edges.

EOPair + OLL Parity

Solve a pair on dBR using the EOPair step from APB, while also solving OLL parity.

LXS

Solve the remaining pieces on the Dw layer

OCLL

Orient the corners using 7 algs.

PLL+Parity

Use 43 algs to finish the cube.

Other ways to solve LL

APB4-A: COLL+ EPLL(and parity)
ABP4-B: ZBLL+ parity
