Is it possible to fetch an existing patchset (that has not been merged into my local machine), change and push it as a new Patch Set? Cindy Langdon @Uncletall put all the steps there and the link, the only thing is that you should not delete the changeId and you should do a git commit --amend. I am giving him a +1. It should be like this On Gerrit, go to the review, select "checkout", on the Download field as opposed to "pull", "cherry-pick", or "patch", then copy the command. On the git project paste the copied link from above This will create a detached head, which is a branch with no name
