[Question] Erase System?

I've been trying to erase the system and it gives me this command
C:\AndroidSDK\tools>fastboot erase system -w
erasing 'system'... FAILED (remote: not allowed)
Any thoughts?

Problem with fastboot command

Hi everyone, I've found my moto x play stucked in a continuous restart loop.
So I've decided to wipe it from the bootloader. But, this time, when I try to flash the same firmware the process interrupt with this series of errors:
(bootloader) Preflash validation failed
FAILED (remote failure)
Click to expand...
Click to collapse
ERROR: usb_write failed with status e00002ed
FAILED (data transfer failure (No such file or directory))
Click to expand...
Click to collapse
Do you have any idea why it is give me this kind of error? I've tried to follow some solution finded online but no-one seems to worked.
My moto is non-rooted and with the bootloader locked.

Bricked my XT1575

Some where down the line, "I think it was because I did not do a factory reset", I bricked my xt1575.
In TWRP 3.0.0-1 If I try to install a ROM I get
Failed to mount '/data' (invalid argument)
Failed to mount '/cache' (invalid argument)
If I try advance wipe and or data wipe in TWRP I get the same results.
Anyway out of this?

I tried that and erase user data
Code:
C:\SDK\android-sdk-windows\platform-tools>Fastboot erase cache
erasing 'cache'...
OKAY [ 0.032s]
finished. total time: 0.034s
C:\SDK\android-sdk-windows\platform-tools>Fastboot erase cache
erasing 'cache'...
OKAY [ 0.011s]

I tried
fastboot erase system
fastboot erase data
fastboot erase cache
Code:
C:\SDK\android-sdk-windows\platform-tools>fastboot erase data
erasing 'data'...
(bootloader) Invalid partition name data
FAILED (remote failure)

Code:
C:\SDK\android-sdk-windows\platform-tools>fastboot erase system
erasing 'system'...
(bootloader) Erase allowed in unlocked state
OKAY [ 0.625s]
finished. total time: 0.626s
C:\SDK\android-sdk-windows\platform-tools>

Ok, I restored from a backup I had.
It's booting up.
"Never know till you try it" They say. But I was hesitant to try a restore as partitions could not be mounted.

IIRC, it's userdata, not data .

L5 E610 - bricked - only fastboot - Secure booting error

Hello out there,
I get a used L5 for my little son, tryed to clear all data (factory reset) and it just partically worked, some data always survied.
I thougt, no prob, then I use recovery. when I tried to boot the recovery mode I saw the Message:
Secure booting error! Cause: boot certification verifiy
HM!
OK Lets try to install a custom recovery (first rooted with kingo, then install twrp 3 with dd)
Jet I only get the Message on booting nothing else is possible. fastboot is available.
Update the ROM with KDZ updater dosn`t work " No connection to phone"
I need *.img files that I can use with fastboot. I tryed to convert a kdz with two tools I found ( a python script and a tool developed for the G series) but that dosn`t work.
Is there a simple way to convert a ZIP to a IMG?
I tryed "fastboot boot recovery.img" and to flash it, but that also dosn`t work (orig. and TWRP)
I also get this:
