I've got one Moto G 2014 XT1069 (dual sim) device, that I might need to flash the factory image. The point is that I'm totally new to this, and although I have found many tutorials on the matter, I'm still a little preocupated with the "official firmware".
As I understood this "flash the factory image" process is analogous to picking one bootable media and reinstalling Windows/Linux on a PC.
Now, what makes me more worried is that I've been searching for this official firmware and all the ones I've found are available through non-official sources like Mega.
This makes me worried: isn't there a risk that someone has tempered the image with some spyware-like or virus-like software that might capture data from the device?
Since these images are made available by non-official people, it makes me very worried about the extent to which is safe to use them.
Is it safe to use those images? Can I obtain one from a official source?
Where can I find one image for this device? I accessed XDA and found this one. It is indeed PT-BR language, which is what I'm searching, but I'm in doubt if I can trust this image and if this is the right image.
Is this the right image and can I trust it? If not, how can I obtain the correct image from a trustworthy source?
As I said I'm totally new to this, so sorry if I said something silly.
