To solve last 2 edges:

From the above you will note:

There are 10 cases and 10 algorithms.
However, I think we need to remember only 2 algorithms:

Single Edge Flip:
(Rr)2 B2 U2 (Ll) U2 (Rr)’ U2 (Rr) U2 F2 (Rr) F2 (Ll)’ B2 (Rr)2

Edge/Flip Swap:
(Ll)’ U2 (Ll)’ U2 F2 (Ll)’ F2 (Rr) U2 (Rr)’ U2 (Ll)2

All the other cases can be converted to the above 2 cases:
1. By inverting one of the the tredges and/or
2. Applying either the first and/or the second algorithms a few times in different combinations
