Xperia XA2 h3113, TWRP/parted (resizing userdata) and black screen after reboot

So I think I've managed to hard-brick my XA2 while attempting to port some things to the AOSP8 source..

 

Device has unlocked bootloader and had ~15% battery charge.

 

After using parted to remove and recreate userdata and resizing it with resize2fs, after rebooting it all I got was the black screen and no LED.

When connecting to PC, no fastboot/flashmode is available, instead QUSB__BULK device pops up.

 

Tried almost any possible combination of power/volume keys for 3, 6 or 120 seconds, disconnecting/connecting cable before/after pressing the combinations - nothing helped yet.

 

Leaving for charging for 1-2 hours seems to have no effect - although I'm not sure how low-current charging mode is implemented on this chipset, and going to leave it overnight. The only visible change is that holding power button for ~10 second causes QUSB__BULK device to reconnect.

 

Any ideas/hints?  I don't believe that parted on mmcblk0 is enough to kill bootloader completely.
