1. Solve the Bottom Layer ⚓︎

Formula 2-1: F D F' (Right side) / F' D' F (Left side)
Formula 2-2: F D2 F' D' (Right side) / F' D2 F D (Left side)

Find a corner piece with white, set the white face as the top face, and memorize the other two colors of this corner.
Case 1: White corner is on the bottom layer of a side face
Method 1: Match bottom color
Locate the white corner on the bottom side layer. If the corner is on the left (right) bottom, align its bottom color with the top-right (top-left) corner color of the front face.
When solving the 2nd or 3rd white corner, simply turn L’ or R to place it; for the final white corner, apply Formula 2-1.
Method 2: Match side color
Locate the white corner on the bottom side layer. If the corner is on the left (right) bottom, align its side color with the top-left (top-right) corner color of the left (right) face, then apply Formula 2-1 to solve it.

Choose either method when the matching condition is met; there is no need to strictly follow only one method.

Case 2: White corner is on the top layer of a side face
Just like the 3x3 cube, use Formula 2-1 to move the white top-layer corner down to the bottom side layer, then solve it following the steps in Case 1.
You may directly rotate the layer containing the white corner as long as already aligned corners stay undisturbed.

Case 3 below follows the same rule.
In the figure below, only two white top corners are solved, so you may directly rotate the right layer for adjustment.

In the figure below, three white top corners are already solved. You must first use Formula 2-1 to shift the white top corner to the bottom side layer, then solve it with Formula 2-1 as instructed in Case 1.

Case 3: White corner is on the bottom face
Just like the 3x3 cube, use Formula 2-2 to move the white bottom-face corner to the bottom side layer, then solve it following the steps in Case 1.
You may directly rotate the layer containing the white corner as long as already aligned corners stay undisturbed.

2. Solve the Top Layer ⚓︎

2.1 Solve the Top Face ⚓︎

Formula 2-3: R U R' U R U2 R'
Formula 2-4: R U2 R' U' R U' R'

The figure below shows 7 possible top-face configurations after completing the bottom layer.

The corresponding solving formulas for these seven states are listed below:

2.2 Solve the Four Top Corner Pieces ⚓︎

Formula 2-5: R' U L' U2 R U' R' U2 L R

First check whether there are corner pieces with matching colors on the lateral sides of the top layer. If such a side exists, take that face with matching corners as the front face, then apply Formula 2-5 to align the colors of the left and right top corners of all four lateral faces.
If no lateral face of the top layer has matching colored corners, set any random face as the front face and run Formula 2-5. After execution, one side will appear with matching corner colors. Take that face as the new front face and apply Formula 2-5 again to finish this step.
