First step, in case you didn’t do that yet: Create a disk image of the partition - you don’t want to try data recovery on the actual data. Easiest is just using dd to dump the disk to another drive.

Next try running testdisk on the image to see if it can find the backup superblocks - if it does you can feed that to fsck to restore the filesystem.

If you know the blocksize of the filesystem you can also run mke2fs with the -S parameter - this will just write the superblocks. Again, only do that on a disk image, not the actual drive.
