How big is the FS?
About 100 G on a 500 G partition. I would only like to recover some
plain text files from it (source code),
I don't need the partition to be mountable again.
What command did you use to overwrite the super
block? Please try to tell us exactly which commands were run.
I had to install FreeBSD on that disk (with Linux, a btrfs partition,
and several free partitions on it).
When using the FreeBSD partition tool, I didn't create or delete any
partitions. I only assigned a
free partition to FreeBSD. When I booted later in Linux the Btrfs
partition did not mount anymore.
There are other ways we can try to pull things off, but you should try
btrfsck -s 2 as well.
btrfcsk -s 2 exits with:
using SB copy 2, bytenr 274877906944
No valid Btrfs found on /dev/sda10
