If you complete the Last Layer, these are 16 ways it could look like. Remove the double Slashes one at a time, and see if it fits(if it doesn't, readd them and try the next)

Also
That is what I came up with on my first try. Does any of this seem familiar?
The first time I tried to reconstruct it, I got this. BO GR BR
Doing the second pair like I've gotten a few different outcomes. I'll link them all here:
  • I think this is the best way to continue from there BR BO GR gives wrong OLL and an A perm
  • This is also the wrong OLL
There are a few more but I won't bother linking them because 1. They aren't very good solutions and 2. None of them were right

This one is has a really good LL but not as easy as the case I had.
This one is terrible and gives the wrong OLL.
I found another solution (didn't track it) that gave the right OLL but it was followed by an E-perm

I've done a bunch more but I haven't found it since Friday night. I got the right solution one time after I started reconstruction but of course it was the one solve where I wasn't paying attention to what I was doing. I'll keep the thread updated if I make any progress.

Edit #1: I said that none of the outcome I got from this start (BR pair first) had the right OLL but I keep coming back to it since it has the most solutions I've seen of the three remaining pairs. Maybe I 'm missing something that another person might see?

I figured this was the best place to put the even though it isn't a full example solve yet, but that is because I need help with something: I need some help recreating a solve. Here is the scramble: R2 B R2 B' L2 R2 B' U2 B L2 U2 R' U B L' B2 D' U B2 L F'
It had an X-cross (yellow) which went as follows: y R' U F R' D2. It solves the green/orange pair in the BL slot. The F2L is what I need help recreating. The OLL was R U2' R2' F R F' R U2' R' which happens to be my favorite case, and I had a PLL skip. If somebody can help me recreate the solve, that would be awesome. If I find the solution on my own, I'll update the post. If you need to know approximately how advance my F2L is (I imagine that would help) I average in the low 14s. If you need anymore information or have more questions that you need answered in order to help, leave a comment and I'll get back to you ASAP. Thanks in advance!
I tried a few times but didn't find that OLL into a skip, although I did find a 6 move OLL +skip.
Good luck!

FB pair in 1st solve and SB in solves 2 and 3 (especially 3) were absolute garbage

I'm still happy with the solves, and at least now I know what to work on next :)

The first time I tried to reconstruct it, I got this. BO GR BR
Doing the second pair like I've gotten a few different outcomes. I'll link them all here:
  • I think this is the best way to continue from there BR BO GR gives wrong OLL
  • This is also the wrong OLL
There are a few more but I won't bother linking them because 1. They aren't very good solutions and 2. None of them were right

This one is has a really good LL but not as easy as the case I had.
This one is terrible and gives the wrong OLL.
I found another solution (didn't track it) that gave the right OLL but it was followed by an E-perm

I've done a bunch more but I haven't found it since Friday night. I got the right solution one time after I started reconstruction but of course it was the one solve where I wasn't paying attention to what I was doing. I'll keep the thread updated if I make any progress.

Here's yet another solution without any cube rotations. Part of the reason this is such a good scramble is because after the easy X-cross, there are lots of reasonably efficient rotationless solutions.

Hi guys, I just broke my 3x3 PB single with an 8.56 (I'm actually really proud of that). I'm trying to reconstruct it and I don't remember very much about the solve since I was just in one of those zones. I know that I had an OLL skip and a T-perm and I'm pretty sure I had a U2 before the T-perm and nothing after. The scramble is L2 U2 B L2 D2 R2 B2 L2 U2 F U2 D B' L' D' F' U B L' R. I would appreciate some help reconstructing it. I'm trying to remember what color cross I did and I'm color neutral so it could be anything but I'm pretty sure it was either white or yellow, probably yellow. Like I said, I would greatly appreciate if I could get some help trying to find the solution. I know I didn't provide very much information so sorry about that but thanks in advance to anybody who decides to help. I'm using alg.cubing.net for the reconstruction and recommend doing the same.

Part of the reason this is going to be so difficult is I don't really see an obvious cross solution. I'm hoping I did the scramble right the first time... Odds are I did just considering my typical scrambling accuracy but I'm still a little worried about it...

I keep getting this solution which is obviously not it and has about 84 million cube rotations during F2L.

Update: I found the solution a few times and i think I did it on white cross? The problem is I'm not paying any attention to what I'm doing -_- Anyway, the cross was not the most efficient solution which doesn't make this any easier lol. It involves a lot of D moves. I think I started with a D or a D' to line up 2 adjacent pieces (I want to say red and green) and then did a D2 and maybe an F to line up something else? And then maybe like another D or D' or whatever and like an L2? Idk it was something like that with roughly that level of efficiency. That probably wasn't helpful but whatever. I'll give an update if/when I find the solution. I wanna say it was similar to this but obviously not that.

Another update: Forgot to mention in the initial post I had said that the lasted layer consisted of an AUF before the PLL, and I was wrong. There was no AUF in any part of LL but there were several cube rotations during F2L.

UPDATE: I found it. Here it is
