How can I repair XperiaX filesystem from Rescue?

Hello guys,
After a pkcon update I had few problems (apps weren't starting etc) and I thought to make a reboot. And I stuck at SONY screen at start, after the "unlocked bootloader" warning.
I managed to enter rescue mode (fastboot boot hybris-recovery.img), I did "4) Perform file system check" with the following results:
Type the number of the desired action and press [Enter]:

Done
Press [Enter] to return to recovery menu...
It didn't seem to do any kind of repair after the error message, so I entered shell / ssh. From there I successfully mounted home partition which I got all the data via "cp -a" without any warning.
Now I would like to try any kind of filesystem check / repair. The Sailfish Image I downloaded 1.5 years ago is Sailfish 2.2.0.29 , I upgraded up to 3.0 ( can't remember exactly the version, for sure not the latest).
Does anyone know anything I could try? fsck seems to not work, and from lvm didn't find anything useful.
I would like to avoid the "Reset your device and spend half day on upgrades / updates / installs and restores"
I don't know much about repairing filesystems, but I wondered if, (assuming your initial crash wasn't caused by corruption in system partition), you dumped system with dd command, then factory reset, then dd'd your system back, maybe would work...
