Moto X stuck on boot, fastboot error.

[TetisTiger]

My girlfriend phone has been stuck on this for quite sometime now and I can't help myself to find a fix for it, since it seems to be a "rare bootloop".

The phone doesn't boot normally, it vibrates upon showing the motorola logo but that's it, won't go anywhere after that.
The only other thing that can be done is entering fastboot but nothing there is useable, since any option you choose from Normal Powerup, Recovery, Factory or BP Tools, it will display the following:

No valid PIV block in SP for system
piv validation failed (system)
Boot up failed

The only option that can be accessed is barcodes, which show the barcodes.

Also, on the top of the fastboot, it shows the following (the phone is not connected to anything via usb):

AP Fastboot Flash Mode (S)
30.BE (sha-34b6ccb, 2015-04-22 12:57:17)
eMMC: 16GB Sandisk RV=06 PV=07 TY=17
DRAM: 2048MB Hynix S4 SDRAM DIE=4Gb
Up Time: 3 minutes
Device is LOCKED. Status Code: 0
Battery OK
Charger Connected

Also the phone can rarely connect to my PC, sometimes it shows USB connected / disconnected but most of the time it doesnt.

This is what shows on fastboot getvar all:

If anyone knows what's up with all of this, please help! Have been trying to resurrect this phone for quite a while now.
I guess the model is the xt1058 (its a Brazillian first gen moto X)

Thanks for the replies!
