M U’ (F’ L’ U’ L U F) M’ (vertical thunderstorm shape & a discontinuous colored corner is on the back side)
F U R2 D (R’ U’ R) D’ R2′ F’ (vertical thunderstorm shape & a discontinuous colored corner is on the front side)
The first one is the symmetrical procedure of OLL42.
For the second, I could have adopted M’ U’ f’ U’ L’ U L f M in the same way, but decided to use the different one which was easier for me.
Finger tricks for the second: F by thumb.
