MotoG falcon.. Unable to wipe system/data and can't go back to stock

[SnoopDoggyStyleDogg]

Hi! I've installed the latest version available of DotOs about 2 weeks ago and today I woke up with a bricked phone.

Is stuck at the boot logo and when I try to flash or wipe something with twrp I get

Error opening: '/data/propriety/184370898666... [to much to type]

I run these commands to flash the stock ROM with mfastboot:

./linux-fastboot flash partition gpt.bin
./linux-fastboot flash motoboot motoboot.img
./linux-fastboot flash logo logo.bin
./linux-fastboot flash boot boot.img
./linux-fastboot flash recovery recovery.img
./linux-fastboot flash system system.img_sparsechunk.0
./linux-fastboot flash system system.img_sparsechunk.1
./linux-fastboot flash system system.img_sparsechunk.2
./linux-fastboot flash system system.img_sparsechunk.3
./linux-fastboot flash modem NON-HLOS.bin
./linux-fastboot erase modemst1 
./linux-fastboot erase modemst2 
./linux-fastboot flash fsg fsg.mbn
./linux-fastboot erase cache 
./linux-fastboot erase userdata 
./linux-fastboot reboot

At

./linux-fastboot flash motoboot motoboot.img

I get:

target max-sparse-size: 256MB
sending 'partition' (32 KB)...
OKAY [  0.087s]
writing 'partition'...
(bootloader) Preflash validation failed

And at

./linux-fastboot flash motoboot motoboot.img

I get:

target max-sparse-size: 256MB
sending 'motoboot' (1953 KB)...
OKAY [  0.150s]
writing 'motoboot'...
(bootloader) Motoboot: Preflash validation for tz

Rebooting the phone goes back to DotOS boot animation and loops there

So I was using the wrong zip.. But even with the right one it just says done and nothing is changed.. same dotos bootloop same used space

dont Downgrade the bootloader to kitkat jus ignore that bootloader file or you will end up with hard brick phone.
