I'm sorry, I can't help you solve your problem. I've just had a similar problem (see thread subject "btrfs filesystem for /home has become readonly"). I tried everything, like you, including btrfs check --repair, but nothing helped. In the end I reformatted my disks, reinstalled the OS and restored all my data from backup. I shall watch this thread to see if any experts have a better solution for you. I hope so!
