I'm new to GitHub and therefore I messed a lot with it, so I need some step-by-step help. Sorry for being annoying :/ Also, before I say anything, I'd have to clarify that I used only GitHub, because I encountered some problems with Git Bash.
Antefact: I forked a repo, did some commits and sent a pull request. However, it had some conflicts. I contacted the programmer, and he said he'll merge my pull request later.
Now, I had to do some other commits, but meanwhile the original repo had been updated with 30+ commits. I didn't know how to do a new updated fork, so i created a new repo, manually uploaded there his updated repo, and did my commits. Obviously, now I can't do a pull request since git doesn't recognize what to compare.
Now, what I'm asking for, is just to be able to do that pull request. I'm also prepared to redo my commits on a new fork/branch, if someone can help me create it. If needed, I can also use Git Bash of course, but I'll need really some step-by-step help because I read something on the internet but every command I launched didn't fit what I read. Obviously I can't delete my first repo because the merge hasn't been done yet.
