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.

Method

1. Opposite Centers: Solve Centers on the L and R layers of the cube.
2. First Block: Solve a 1x3x4 block on dL.
3. dR Edges: Pair the edges that belong on dR while placing them on dR.
4. Last 4 Centers: Solve the last 4 centers using the M slice and U layer. This is similar to the Yau method when doing L4C
5. 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.
6. EOPair + OLL Parity: Solve a pair on dBR using the EOPair step from APB, while also solving OLL parity.
7. LXS: Solve the remaining pieces on the Dw layer
8. OCLL: Orient the corners using 7 algs.
9. PLL + Parity: Use 43 algs to finish the cube.
