[Q] What's the difference between the XT1575 and XT1572 regarding system image?

I live in Germany and will soon receive my style, maybe tomorrow. My question:

There are several issues, that points to different system images of the XT1572 and XT1575. I assumed, that for example the lte channels (= modem) are the only difference, but there are some others, too. In an other thread, an user described a problem with using WiFi correctly, after flashing the system image of the XT1575 on a XT1572.

This would result in different roms, if development will start soon. Is this correct? Does anybody know, what's the real difference of the two devices regarding software/hardware? Are there different WiFi modules? Can you please support me?

I'll wait with rooting my device until I'll get some clearance about this (and maybe until M via OTA arrives).

XT1572 factory recovey image (Firmware)

Hello guys, I would like to Unlock my BL and root my device, but I'm afraid that I will be not be able to update to Android 6 by OTA.
So I was looking for some stock firmware or recovery image, in case I need to lock my BL or get back to stock.
I was thinking about Unlock BL, intall TWRP, do a backup, and than root. And case every thing goes wrong, I would need stock recovery so I can lock my BL again.
My device is Brazilan one 2 SIM, and XT1572.
The only site I founded the firmaware is this one http://www.phonandroid.com/forum/fla...e-t132486.html

What do you guys think, should I take the risk?
Thank you!

Can someone post the stock system image for XT1572 (moto x style)

Hi, I bricked my moto X style, the XT1575 system image allows it to function as a phone, but wifi is broken, would it be possible for someone to make a copy of their XT1572 system.img/ twrp backup of it? thanks

Restoring Moto X to stock (Style, XT1572)

I've just been planing out how i'm gonna root, twrp, exposed etc. Of particular concern to me is being able to return to stock when the marshmallow ota arrives. I came across this, regarding the moto x 2014

"Thanks. I'm pretty sure I can just fastboot flash recovery and then do a factory reset and be back to 100% stock. That's what I'm going to try anyway. Update, it worked. Just fastboot flash recovery recovery.img then factory reset and my phone is back to stock. Now to send it back to Motorola and get my new one!"

So do you think i'll be able to do this? (using the recovery.img for the moto x style, of course)

Thanks
