Error to "flash" the fastboot in Moto X Play XT1563

[dan_araujo]

Hello guys,

I'm trying to downgrade my Moto X Play XT1563, I found a tutorial on the Internet using the fastboot for such a feat. From what I saw, many people use this tutorial to upgrade or simply go back to what it was before "flash".

But in the first command line, when I type in CMD, an error appears, you see the image of this error:



The tutorial is for this purpose doubt

1) Extract the Fastboot / ADB and images (zip ROM), extract the two zip's to a folder of your choice
2) Restart your phone mode 'Bootloader' (Turn off the cell and then press the volume button (minus) and (power for 2 seconds) and then release the power.)
It would be interesting to have activated in the "Developer options" the option "Allow OEM Unlock"
3) Now the CMD, enter the commands:

NOTE: system.img_sparsechunk may contain name or number, so check if you have only modify the hour.
