over 2 GB size limit, repository is in read only mode, I want to delete some files, but I can't push, what can I do?

There may be a better answer to this question but you could:

1. Pull the repo 
2. prune it locally (making what ever deletes you can)
3. gc it
4. push it back to a different repo to see if it gets the size down.
5. If it does, then delete the repo from Bitbucket server
6. re-create it and re-push it.

The problem with this is that you'll lose your pull request info.
