[Moto Z Play Questions & Answers] echo92:
Thanks for the getvar info, it's useful info.

1)Despite receiving the device as new from Amazon UK, the bootloader is reporting that the device has an unlocked bootloader: (bootloader) securestate: flashing_unlocked . Normally, on a new device straight from Motorola or Amazon, you'd see OEM_locked and not flashing_unlocked. This is likely why you don't have Android Pay. Unless Amazon or someone unlocked the bootloader, this appears to be as a result of (a previous owner?) the unlock key being requested against the device. I honestly don't know if there's a way to unlock a bootloader without requesting an unlock key from Motorola...

2)With the bootloader unlocked, the warranty associated with this device is voided, as reflected by the (bootloader) iswarrantyvoid: yes flag (which is a shame, as if this was a properly brand new device, it'd have 2 years warranty with Motorola as is now standard with UK and EU devices - https://help.motorola.com/hc/apps/settings/legal/global/en-gb/index.html?t=T1507061106 ) . It's possible any repairs would require the device IMEI being checked, and it may show up in Motorola's database that this device has a voided warranty.

3)As mentioned before, looks like you have the US retail firmware on your UK device. Furthermore, your bootloader version and stock ROM version do not appear to match. Your bootloader C1:07 appears to correspond with the April 2017 Nougat NPNS25.137-24-1-9 yet you have a Marshmallow system which appears to be the November 2016 security update. Attempting to take an OTA update with a mismatched bootloader and system (especially a newer bootloader than the system) is likely going to result in a nasty hard brick, where your device fails to boot and function at all. This normally requires a blankflash to resolve.

EDIT - one more thing, do the IMEI numbers on your device match the IMEI number written on the box?

Overall, this device doesn't seem to be in a good state for being supposedly new. Though this is conjecture, the evidence suggests that the previous owner unlocked the bootloader, then flashed a Moto Z Play firmware (e.g. from here https://mirrors.lolinet.com/firmware/moto/addison/official/RETUS/ ), perhaps in an attempt to get US radio bands? As there's no bootloader unlocked screen - possibly from a custom logo flash - they may have been able to return the device to Amazon UK without questions. I still am confused how this device was sold as new, despite the getvar all info indicating this device is anything but new. I'm sorry, I don't like to be the breaker of bad news.

Off the top of my head, you have a few options:

a)Return the device to Amazon, exchange it for a new device. When you receive the device, check the fastboot getvar all info again. If this is genuinely new, you should see OEM_locked under (bootloader)securestate and of course your warranty should be intact. Your Moto Mods and Android Pay should also start working.

b)Keep the device and attempt to flash the Nougat stock fastboot ROM. I'm not familiar with Moto Z Play firmware (no thanks to Motorola's naming convention), but the NPNS26.118-22-1 Android 7.1.1 stock ROM should suffice. I'm hoping someone else can confirm that this firmware was deployed to retGB (I've seen it on retEU), as Motorola seems to have a habit of deploying different firmwares to different retail channels - I do not know if this applies to Moto Z Play devices recently, or if Motorola has unified its firmware builds.

By flashing this, you should bring your device up to the same patch level (rather than having a new bootloader/old system), and also if the build is deployed for retGB/retEU, you should start getting OTA updates. This process of flashing should also wipe your device clean, for a fresh start. Depending on the source of the stock ROM (as these stock firmwares are leaked), if they have been signed with the correct cryptographic keys, you could also lock your bootloader, which should also give you Android Pay and Safetynet passing (if Safetynet does not pass, some apps from the Play Store may not work). Alternatively, you could keep your bootloader unlocked and root with magisk, which may let you pass Safetynet and use Android Pay. Either way, you'd also be updated to a newer stock ROM than you had and should be able to use Moto Mods.

If you choose to flash, you'll likely want the NPN26.118.22-1 August 2017 stock firmware - here's a download repository here: https://firmware.center/firmware/Motorola/Moto Z Play/Stock/ As I'm not fully familar with Z Play flashing, you could use the firmware flashing instructions here to flash this stock ROM https://xdaforums.com/moto-z-play/how-to/guide-relock-bootloader-to-lasted-stock-t3718190 The fastboot flash should occur as you're flashing stock ROM firmware, regardless of whether you had a custom ROM or stock ROM previously. The first set of commands should flash the stock firmware onto your device, the second set should lock your bootloader (though locking if you're already on stock firmware seems to require enabling OEM unlocking under Settings>Developer Options). The major point to not flash stock firmware older than the stock firmware on your device.

Bear in mind, if you do decide to keep the device, you may not have a warranty, as the warranty may have been with the original owner, who voided the Motorola warranty. I'm not sure if Amazon UK will still honour the warranty despite selling the device as reportedly new, especially now the device bootloader is unlocked (through no fault of your own), so any issues you may encounter later on with the device might be troublesome to resolve. I'm hoping UK distance selling/consumer laws will cover you for at least 2 years, but might be worth getting clarification from Amazon and Motorola, in case you have to pay for repairs. Just a thought, Motorola may be able to check when the bootloader unlock key was requested against your device's IMEI, and thus you could have that as evidence that you did not unlock the device bootloader (if you've got the paperwork that says you got the device long after the unlock key was requested). Again, I'd seek advice from Amazon UK. If you're concerned about repairs/warranty, then the easiest thing would be to exchange the device for a brand new one.

Good luck whatever you decide.
