Hello,
Can I downgrade completly with the bootloader on Marshmallow and then upgrade to Nougat?
I want to lock my bootloader.
My G2 bricked after doing this. But I don't know if this would happen to my G4 Plus again

If you wish to simply re-lock your bootloader, the easiest thing is to flash this fastboot stock ROM (which is Nougat) and use the locking script as directed in the first post. https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1640-43-athene-npj25-93-t3549369 Of course, this may wipe your data - so back up, and the relocking may or may not work, in which case you may have to wait for a more up to date fastboot stock ROM to become available.
If you were to downgrade to Marshmallow, you cannot downgrade your bootloader and GPT partitions, at best, your existing bootloader would try to prevent you from downgrading those partitions. At worst, you'll brick your device again if you were to flash those - though we've got possible ways of fixing that, it's not a route I'd want to go down. Flashing the rest of Marshmallow is no problem, however, ensure you have the correct MM firmware for your device and territory.
Will this version work for my country(Germany) without OTA trouble?

Should be okay to flash - the 93-14 build appears to be the global build that was deployed by Motorola, and should be eligible for the 93-14.4 (March 2017 security update) whenever that arrives in the EU/UK I've flashed the stock ROM onto my XT1642 several times without issue.

THANK YOU IT WORKED AND THE WARNING DISAPPEARED. I am on Nougat, locked and its working like a charm
I WOULD KISS YOUR BUTT IF ITS HAVE TO BE
Everywhere I've been looking for the stock ROM for my phone (Moto G4 XT1622 RETEU channel), but I just find links to some sketchy file hosting sites with old versions. Is there any official way to get the latest stock ROM?
I was on LineageOS for the longest time but decided to go back to Stock because a game got updated and doesn't work on any custom ROM anymore.
The ROMs provided by Motorola are old - 6.0.1 (Build MPJ24.139-64) to be precise. As far as I know the update to Nougat has long been released. But I installed the old version anyways, thinking that I'll get the new one via OTA. But every time I check for an update it tells me I'm on the latest version.
Is it because I have an unlocked bootloader? I already tried to relock, but if I understand correctly, I need a newer version of the stock ROM to lock it. ("preflash validation failed / security version downgrade"). But I don't have or can find a newer version xD Am I screwed?
Look on MOTO G4 Plus forum on XDA. Both are Athene and should work for both devices. Revivor2, CreamPie Nougat, and stock by DroidPhil are roms that can be flashed via TWRP. You can download official stock roms and flash via FASTBOOT also. March Security Update is the safest official 7.0 stock rom to flash. June Security Update is an OTA addition to March's one and can cause brick on some devices if you want to roll back to an older rom like March Security Update.

Seems you bricked your phone by downgrade the bootloader...
Did you tried to follow the unbrick guide here https://forum.xda-developers.com/moto-g4-plus/help/solved-unbrick-hard-bricked-dead-t3585016
Otherwise please provide on which rom version you are before downgrade to marshmallow and also the device type you have.
I'm sure @echo92 will help further :good:

As an aside, you cannot safely downgrade and use OTA updates. If you downgrade, only use stock firmware to update. You cannot downgrade bootloaders and thus using older OTA updates on your device corrupts your bootloader.

You won't be able to flash another blankflash unless your device is in the Qualcomm HS-USB 9008 mode again (in other words, you hard bricked by corrupting your bootloader again).
I'm hoping as whatever blankflash you used worked properly and thus you shouldn't have issues flashing the latest firmware. However, they can overwrite a damaged bootloader with the dummy bootloader, and as such you need to verify you're flashing the correct blankflash. The inbuilt checks should stop you from flashing the wrong blankflash however.
If you still want to revert back to Marshmallow, then do not use OTA updates at all.
As an aside, do not always depend on these blankflashes, Motorola is updating the bootloader with every firmware release and there's always a chance the blankflashes may not work anymore. We're not supposed to have these blankflashes (leaks from generous engineers are our source) and so we don't know if we can get another one should the current blankflash stop working.

Did you re-flash the latest firmware? https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 For NPJS25.93-14-13 (Nougat, Dec 2017 build)
If not, then your device is still with a mismatched bootloader and system - you have the December 2017 bootloader but the much older Marshmallow system. That means any OTA update you take may well keep hard bricking your device unless you re-flash your device to have firmware of the same patch level (bootloader and system). Then, you should be okay to take OTA updates.
This is the major problem with downgrading - OTA updates have the ability to overwrite your bootloader without checking first if your bootloader is the same patch level as your system. As you've downgraded, this is likely why older OTA updates brick.
Un-brick your device then use the flashing instructions here https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-hardbrick-solved-guide-t3657761 with the latest NPJS25.93-14-13 firmware. Do not use/install OTA updates until you've re-flashed the latest stock firmware.

The link to the latest firmware was the first link I gave you in my previous reply... NPJS25.93-14-13 is the latest stock ROM for India, Brazil and EU devices.
Yeah, flashing the May 2016 or March 2016 firmware really won't help you - again, as your bootloader is December 2017 flashing older firmware and attempting to take OTA updates will just keep hard bricking you until you reflash the December 2017 firmware, or if you do not use OTA updates. You cannot downgrade bootloaders usually.

Should be, please use the latest athene blankflash in the Unbrick guide: https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-hardbrick-solved-guide-t3657761 and the latest stock ROM as mentioned. I would also advise deleting any old stock ROMs - Marshmallow or Nougat - on your computer, unless you are confident you will not use OTA updates whilst downgraded. Motorola and other OEMs appear to have not designed protections into their updates for downgraded devices (and assume that you've taken responsibility ever since you unlocked your bootloader).
If this doesn't work, then you'll either have to wait for another newer blankflash to be leaked (perhaps when we get the Oreo update, but again, it's by chance whether we get another blankflash), or be willing to pay for a motherboard replacement. A motherboard replacement appears to be in the range of 7000-10000 rupees or your regional equivalent.

Depends - if it's an old blankflash for our device (for Snapdragon 617, MSM8952), it'll likely fail as the blankflash, in communicating with the device's bootloader, determines the blankflash is too old to repair the bootloader. Blankflashes appear to send a programmer over to your device which verifies that your device bootloader is not newer than the blankflash, else you'd be downgrading your bootloader and possibly causing a security issue. Thus, your device may not be rescued and require a new motherboard. We saw plenty of these incidents when users downgraded to Marshmallow from Nougat 6 months ago and then tried to use OTA updates, and it was only with the leak of a newer bootloader version B1:06 compatible blankflash that people were able to rescue their devices without spending a lot of money. Without that blankflash, I think we have very limited means of rescue. We cannot make these blankflashes as they have to be cryptographically signed and built by OEMs like Motorola, I think to maintain the bootloader security, as such we do not know if we'll get a new one. In theory, we could make a loader image - a complete image of a working device - to try to bypass the bootloader corruption without needing a blankflash. That has had some success on other devices, but hopefully you should need neither a blankflash nor a loader image.
We've seen instances of other Moto devices' blankflashes rescuing devices (e.g. Moto Z2 Play rescuing Moto Z Play and G5 Plus), however, their CPUs are very similar. Our Snapdragon 617 is not used by any other Motorola device, so we have a very limited source of blankflashes.
I would hope blankflashes are in general well programmed enough to not flash onto devices they are not meant to flash onto, else if they could flash onto a different device, you could really screw up your device.
In summary, an older blankflash likely just won't work, and you'd either have to wait for a newer blankflash or pay for an expensive repair. Unless you are willing to do either, I would be very careful in future with downgrading.

Hey there !
I have a Moto G5 Plus International edition (XT1681) with firmware NPNS25.137-92-4 (latest January Patch).
I want to know what firmware to download from here (https://firmware.center/firmware/Motorola/Moto G5 Plus/Stock/) for factory flash not to get bricked like an idiot.
I don't know which one is good
Thanks
The last 2 ROMs are for your device, if you have a custom recovery I recommend to install the flashable version from this link .
https://forum.xda-developers.com/g5-plus/development/rom-twrp-flashable-stock-builds-t3675616
Here are the same version of your device NPNS25.137-92-4 (20180101 security patch)
Oh nice !
Is it OK to OTA update on these flashable .zip ? As I have also modified the kernel which is not stock anymore :/

i didnt try to flash over a fastboot rom, maybe you cant do that.
Thanks
But basically, what I need is flashing full stock firmware (with recovery and kernel), no matter if it's january update or not. Just the factory images I had when I bought the phone. And I don't know what version is OK for my phone (XT1681 with NPNS25.137-92-4 now) 'cause I don't want to hard brick it when OTA updating (to Oreo for example)
From your link the last 2 ROMs are the same so you can use both.
You are on stock right? Do you planning on flashing custom ROMs? If you flash Oreo ROMs and you want to downgrade flashing fastboot rom maybe you lost volte.

Right now I'm on stock NPNS25.137-92-4, with TWRP recovery + Magisk root + ElementalX kernel
I'm not planning to flash any custom ROM for the moment. When the official Oreo update comes out, I want to update. But I know it won't go well if I OTA update it with my current configuration. That's why I want to be able to flash stock with fastboot (rough clean install), no matter what version I get : All i want is to be able to update to Oreo when it's out. Problem is, I don't know which image I need to download from here : https://firmware.center/firmware/Motorola/Moto G5 Plus/Stock/
I know it's there, but don't know exactly the good version.
This is for our device xt1681
https://firmware.center/firmware/Mo...ubsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
I'm on flashable stock with ex kernel and magisk, when the Oreo ota start rolling out I'll wait for flashable rom so I'll can upgrade (dirty flash) so I don't loose anything.

If your device was flashed with stock firmware newer than NPN25.137-15, I would strongly advise against flashing the NPN25.137-15 stock firmware.
The reason is that downgrading stock firmware downgrades your system, but not usually your bootloader (your bootloader will likely report a security downgrade/pre-flash validation error). As such, you'll have a newer bootloader but older system (in terms of patch levels). For example, you have the NPNS25.137-92-4 stock firmware (before flashing TWRP), so your bootloader is the Jan 2018 patch level. You flash this NPN25.137-15 firmware - you have a Jan 2017 system, but still a Jan 2018 bootloader.
The downgrade generally goes okay. However, taking OTA updates with this mismatch in bootloader and system is generally what results in hard bricks; the OTA update checks for your system patch level - in the above example, you'll probably get the OTA update to upgrade from NPN25.137-15... However, your bootloader is not the NPN25.137-15 patch level bootloader, as such your bootloader may get overwritten by the OTA and gets corrupted in the process, leading to hard bricks. This scenario isn't just applicable for the NPN25.137-15 update, this potentially applies if you flash a stock firmware older than what was on your device and then attempt to use OTA updates (unless you could flash the stock firmware directly preceding the firmware you had).
Easiest way is to re-flash the same stock ROM build you had before flashing TWRP. I don't see any NPNS25.137-92-4 stock ROMs leaked yet from the Motorola Firmware Team page https://androidfilehost.com/?a=show&w=files&flid=171014 or firmware.mirror but hopefully they'll be along soon.
If you're on stock NPNS25.137-92-4, in theory you could flash NPN25.137-92 (the build directly before the NPNS25.137-92-4 Jan 2018 security update), so the next OTA update would update your device to NPNS25.137-92-4 - the OTA would be simply patching your device to the same build it's currently on and in theory that should work. NPN25.137-92 is one of the firmwares currently available so may be worth thinking about. Best thing though is to flash the NPNS25.137-92-4 firmware or newer firmware that is the correct build for XT1681 devices.

Pretty much, yes (or at least it minimises the chances of a hard brick). If you really want to flash older stock ROMs, please do not use OTA updates at all. Ignore the OTA prompt or freeze the Motorola OTA updater if you downgraded your stock firmware. It's not fun seeing a £150-200 (or your regional equivalent) device hard bricked.
However, with Motorola's habit of releasing different builds to different regions, please ensure you flash the correct build for your device, else the Motorola servers may not issue OTAs if you're on the incorrect series of builds for your software channel. The latest available leaked firmware for your device appears to be NPN25.137-92 (we don't have access to NPNS25.137-92-4 yet).

Pretty much, yes (or at least it minimises the chances of a hard brick). If you really want to flash older stock ROMs, please do not use OTA updates at all. Ignore the OTA prompt or freeze the Motorola OTA updater if you downgraded your stock firmware. It's not fun seeing a £150-200 (or your regional equivalent) device hard bricked.

That was roughly what I figured out but damn, those explanations, thanks buddy :highfive:
The January update's bootloader is the same bootloader that the November security patch update has. You can flash the
POTTER_NPN25.137-83_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC files from fastboot (skip gpt.bin) then OTA to 93 (November Patch), then OTA to 93-4 (January Patch)
The OTA will not brick the phone since the bootloader the OTA flashes is the same one it is currently on.
Also, this is what I did to get onto the January Patch so I can confirm my phone works fine and did not brick.

yeah i cant apply normal OTA over flashable rom. I was on NPN25.137-92(flashable) i download NPNS25.137-92-4(flashable too) i dirty flashed it and it works perfect without lose my stuff
I ordered XT1681 International version from Amazon.ca. I replaced the recovery with TWRP. I have two questions.
(1) I am prompted to install 137-92-8 via OTA. Where can I find this TWRP flashable ROM for this version ? I am on 137-92-4.
(2) Is there any other compatible stock ROM that I can install on it ? The OTA message is in Spanish. My preference is in English and as long as it supports the dual SIM and the NIC.
Thanks.

Just to reply to myself for (2). I found the following link

I'm having Moto g5 plus Indian variant xt1686. I have installed a custom ROM Resurrection remix and I'm currently running it.I want to get back to stock rom. I went through many existing threads only to get myself confused. I want you guys to help me get back to stock ROM so that I can get OTA updates.
1. I have working volte and IMEI till now. I didn't take back-up of persist or efs as I was lacking knowledge. Can I take back-up of those now for going back to stock. If yes then suggest how?
2. I don't remember my build number from which I unlocked my bootloader. Should I lock the bootloader again to get OTA? If not then please suggest any way to get back to stock whether Oreo or nougat (get updates to Oreo then).

From what I believe, you should definitely backup your EFS and Persist right now while it's all good.
If you don't remember your last stock build number, it is safe to use the latest build for your region.
Once you flash a fastboot ROM and everything's good to go, there's absolutely no need to relock bootloader as the script in the OTA only checks for system modifications and if it finds any on your phone, the OTA will not be applied and the update will eventually fail. To ensure that you are able to apply OTAs without any hassle, I recommend you don't do ANY system modifications like root or camera mods or similar. Stick with the core OS and you'll be good to go.
You can alternatively use TWRP flashable ROMs by @NZedPred, they're like a newbie-proof solution to getting to stock ROM from virtually any ROM without losing any functionality as they only flash the OS part of the ROM and rarely do any changes to the HW functionality of the ROM like Radios and Sensors. If all else fails, you can always flash a TWRP flashable stock and be ready to go.
Or
You could simply download the Oreo fastboot ROM with the August security patch which is available at the moment but isn't the latest one as the latest October security patch rolled out to RETIN devices just a few days ago so I doubt that the full fastboot ROM would be available this early. But then again, if you flash the Oreo August patch, you can take the OTA to October patch and be just fine.
Note:
But a bit of advice, if you're planning to go back to Nougat using a Nougat fastboot ROM, I'd highly recommend the TWRP flashable as one can mess stuff up while trying to downgrade using a fastboot ROM as Moto phones have problems downgrading. It's all about these two partitions called "gpt" and "bootloader" which when not paying attention to while flashing can cause a hard-brick.
A safer approach would be to skip these two partitions while using a fastboot ROM to downgrade but I'd be honest and would suggest you to wait to be sure this would work as I myself haven't tried this while downgrading from one Android version to another as Oreo bought with itself some Modem and a few other changes in partitions as compared to Nougat.
If I were you, I would wait for some to confirm the part in the "Note" just to be absolutely sure that it'd work.
Thanks for the response
