Installing Mazda firmware update...Help!

Hi, I need help as I'm trying to install the firmware 70.00.100. It is consistently failing on 54%, then it reboots, attempts to install again and fails. I did install the failsafe version, I don't know if I could leave it and try later or if I have to continue until it finishes.

I have a Toyota Yaris iA 2018 (it is basically a rebranded Mazda 2). Please, any help would be appreciated as I'm starting to freak out.
