All edges paired up but 2. I can get the last layer just about done, but the cycle moves I've come up with sometimes don't cut it. I'll have 2 pairs of say purple/red that I wanna make purple/purple and red/red

all edges paired but one is yellow down. I'm able to pair up all of them but my cross is missing one pair. This is the most common

all edges solved, 2 corners unsolved. This case is just annoying because I've never come across this. I had this problem with the 2x2x2, but I found an alg that works but flips edges. This doesn't help me for the 4x4x4

with that being said, maybe I'm going about it wrong. Here is my method

all centers, top pairs, first 3 layers pairing, pairing last layer edges, orienting edged, orienting corners, flipping corners.

Maybe the way I'm solving it is counter productive.

**so I'm looking for tips on these cases without directly being told what to do**. I've been trying to do this alone, but without a point in the right direction, I've reached my limits
