 7.1 Solve the first center 7.1.1a Construct a matching 2x1 block 7.1.1b F (D d) 7.1.2a Pair up the remaining center cubies 7.1.2b U2 (R r) 7.1.3a Join the blocks together 7.1.3b R' (F' f') 7.2 Solve remaining centers 7.2.1a Swap Ufr with Ful 7.2.1b (R' r') F (R r) 7.3 Solve remaining centers 7.2.1a Swap Ufr with Ful F  (R' r') F (R r) 7.4 Swapping opposite centers 7.4.1a Swap the Up and Bottom centers 7.4.1b (R2 r2) U2 D2 (R2 r2) 7.5 Swapping adjacent centers 7.5.1a Swap Front and Right centers 7.5.1b (U' u') R2 (U u) (D d) R2 (D' d') 7.6 Solve the first four double edges (dedges) 7.6.1 The other edge is in the top layer on the left R U' R 7.6.2 The other edge is in the top layer on the right U' F' U F 7.6.3 The other edge is in the bottom layer on the left D F D' F' 7.6.4 The other edge is in the bottom layer on the right R' D R 7.6.5 The other edge is in a middle layer R U R' 7.7 Pairing up the dedge (D' d') 7.8 Storing the dedge in the U layer L' U L (D d) 7.9 The dedge is in the middle layer 7.6.1 The other edge is in the top layer on the left R U' R' 7.10 Solve the final four dedges 7.10.1a Other edge is in the FL position Do nothing - the dedge is solved 7.10.2a Other edge is in the FR position Go to 7.11 7.10.3a Other edge is in the BR position R2 7.10.3a Other edge is in the BL position B2 R2

 7.11 The final four dedges: Flipping the edge pair 7.11.1 The other edge is in the dFR position goto 7.12 7.11.2 The other edge is in the uFR position Then goto 7.12 R U R' F R' F' R

 7.12 The final four dedges: Final step 7.12.1 (D d) R U R' F R' F' R (D' d') 7.13 Fixing orientation parity 7.13.1 The FU edge needs to be flipped - leaves corners unchanged Use one of these l2 B2 l U2 l U2 x' U2 l U2 l' U2 l U2 l2 U2 x r2 B2 r' U2 r' U2 x' U2 r' U2 r U2 r' U2 r2 U2 x r2 B2 U2 l U2 r' U2 r U2 F2 r F2 l' B2 r2 7.13.2 The FU edge needs to be flipped - corners are altered (L2 l2) B2 (L l) U2 (L l) U2 x' U2 (L l) U2 (L' l') U2 (L l) U2 (L2 l2) U2 x (R2 r2) B2 (R' r') U2 (R' r') U2 x' U2 (R' r') U2 (R r) U2 (R' r') U2 (R2 r2) U2 x (R2 r2) B2 U2 (L l) U2 (R' r') U2 (R r) U2 F2 (R r) F2 (L l') B2 (R2 r2)
