Back in September, Motorola rolled out Android 7.0 Nougat OTA update for US variant Moto X Pure edition (XT1575) with build number NPH25.200-22. If you have not updated your device yet to Nougat, or unable to install the OTA (over the air) update for some reason, you need to install the Nougat factory image manually. Read on to know how to download official Android 7.0 Nougat update and install it manually on Moto X Pure XT1575.
In this guide, we show you how to download and install stock Android 7.0 Nougat firmware on Moto X Pure XT1575. Read the step by step guide given below carefully and then proceed to update your Moto X Pure to Nougat. After installing Android 7.0 Nougat update on your Moto X Pure XT1575, you can enjoy Google Duo video calling app, redesigned notification panel, improved data, battery and system stability features.
If you have not got the OTA update on your device, check it by going to Settings > About phone > System updates and check for the update. If update found, tap ‘Yes I’m in’ and continue. This is the safest method. Alternatively, follow this guide.

If you have received “Preflash validation error”, it means you are attempting to install a firmware image that is older than what you have installed currently on your device. Any question? Leave it in the comment section below.(Source – Reddit)
You need to add spareschunk 8 & 9 to the commands also if your not wanting to relock your bootloader omit the first command. The first modem cammand usually needs to be run twice to take.
I just want to say thanks. I moved to LineageOS for quite a while because of Android 6 problem with screen overlay. It was just too frustrating. Lineage worked for me, but never perfectly of course. I’d been meaning to move back to official Moto software when 7 was available, and never did. I found your instructions, and it went smoothly and quickly.
The only problem is that Google doesn’t recognize my Lineage backups, so I’m having to redownload all my apps and rebuild my screens. Worth it, to have Android 7 with native Moto software. Hopefully no more weekly crashes.
