Moto G emmc bricked?

Got a problem, moto g 2013(falcon) here with unlocked bootloader
Problems started happening after a drained battery, and multiple times trying to get it to charge again
Can't wipe userdata and cache in recovery, it will freeze.
Can do it in fastboot, but after a reboot everything is still there

More importantly, partitions get mounted read-only, the rom is stuck in a bootloop.
In the kernel we get many messages like these:

[/spoiler]

Also a problem, tried to flash stock images through fastboot, and even another version of TWRP but the version number doesn't even change after a reboot, fastboot shows success but it actually didn't do anything.

Is this a dead case or does anyone know a remedy?
