[Help] [Custom Rom] How to revert back to stock rom

Hello Moderators,
My Device Model : XT 1644 64 GB variant
Current Rom: Lineage OS
Bootloader Status: Unlocked
Since the US variant didn't get the nougat update, I decided to unlock my bootloader and switch to a CM based ROM.Though I love it I've been facing a lot of issues in fingerprint sensor and advanced settings
Now I'd like to go back to my stock ROM and I've few doubts
1. If I don't lock my bootloader again after switching to stock ROM will I be still eligible to receive the official updates?
2. This link to stock ROM https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1643-updated-signed-t3460695 says that it's for the Indian version will it work on the US versions?
3. After flashing the stock ROM will it be okay if I follow this thread and update to nougat https://forum.xda-developers.com/moto-g4-plus/how-to/xt1643-ota-nougat-t3483943?
4.Does the soak test have any bugs?
5.If I'm on the soak test and Once the official nougat is available for my device what should I do?
I have a twrp backup of my stock ROM too

1) Yes - you should still be eligible for stock OTA updates even with an unlocked bootloader - as far as I understand, the main thing the OTA checks is whether your recovery and kernel/system are stock and unmodified.
2) I didn't see any reports of that XT1643 update working for XT1644 devices - try this thread https://forum.xda-developers.com/moto-g4-plus/how-to/xt1644-firmware-t3454980 Looks like a few reports suggest the .48 firmware works.
3) If I recall, US firmwares don't have the right build versions for that Nougat soak (think US is ending in .48 or .64/65?), so that file may not work. Also, the soak tests available lead to a broken upgrade path - besides the 75.2 soak test, as I understand there are no other soak test updates available to bring you back onto the OTA update, meaning you'd have to flash another Nougat firmware.
If you still desire Nougat, perhaps try flashing the 93-11 (v7.0, Nov 2016 security update) or 93-14 (v7.0, Dec 2016 security update) stock ROMs; they are not the soak tests, rather they appear to be the full Nougat stock ROM. The 93-11 update also appears to be signed by Motorola (though not released by them through official channels) and possibly is the same for 93-14. Still, if you're interested: https://forum.xda-developers.com/moto-g4-plus/how-to/android-7-0-install-nougat-official-t3531612 for the 93-11 and https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1640-43-athene-npj25-93-t3549369 for 93-14. Also, if you flash these, you may omit 2) since you'll directly flash to Nougat.
4)Nougat 7.0 seems to be a mixed bag for many - though the OS appears to work well for some, others have mentioned lag, battery drain/heating issues with Nougat as well as some interface issues. Your experience may vary.
5) If you wish to move back to the official OTA channel updates once you've updated to Nougat, you may be lucky in that once Motorola releases the Nougat OTA, the released build may be 93-14, so any subsequent OTAs should flash okay (provided 1) is still applicable), since your installed build matches what the OTA expects for future updates.
If you wish to downgrade and then install the official OTA to ensure you have a verified firmware from Motorola, you may wish to downgrade to MM, then update via OTA. A guide like this may help (https://forum.xda-developers.com/moto-g4-plus/how-to/guide-downgrade-to-marshmallow-nougat-t3515961) but ensure you do not downgrade your gpt or bootloader partitions else you risk damaging your phone - just omit those commands flashing either of those partitions. Someone correct me if I'm wrong, I think it's these commands you omit when downgrading:
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
Good luck either way

HELP, Can I downgrade to Stock Marshmallow and Upgrade to Nougat?

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

What happened to my phone!? Bootloader downgraded

I was in B.05 version (the one of the 14-4 update) and i flashed the (soak test?) -11 build, with bootloader,partitions and everything, i was hopping the bootloader didn't flash (like always showing error) , but it did,it flashed the bootloader, and now i'm in B0.3 version, and the phone didn't brick, i thought it wasn't possible....!!
I'm happy because i was looking for a way to downgrade the bootloader, but i never thought to do it like that.......
What do you think??
UPDATE: NOW, i flashed Marshmallow firmware and the bootloader downgraded correctly. i have had flashed marshmallow before, and it gave me an error, but now it flashed and now i'm in B0.0E version....
HOW?!?!?

If it's the 93-11 build, that's not a soak test - that was the first of the official Nougat updates (though only formally released in India if I recall - so in other territories you may not get any OTA updates).
Regardless, as I understand it, downgrading your bootloader may not brick your device - what may brick your device is downloading and updating via OTA updates subsequently.
By the way, what was the reason for wanting to downgrade your bootloader? If you wanted to downgrade your system, you could have just flashed Nougat or Marshmallow, just not flashing the GPT or bootloader partitions.

The reason is that i want to update by ota from marshmallow to nougat to get a smooth nougat, because if i flash it with fastboot it has got a lot of lag (i don't know why, but is very noticeable)
I just updated from 6.0 to 7.0 (-14) so it really downgraded the bootloader.
So if someone else want to downgrade the bootloader, you can flash -11 bootloader!!

Update. Again; flashed marshmallow firmware and bootloader downgraded too. What is going on??

Fastbooting Marshamallow will include Bootloader partition by default--you have to skip bootloader flashing to NOT downgrade bootloader. N bootloader will work fine with Marshmallow.

Now i updated to 14-8 version (B.06 bootloader version) (June patch) and i CAN'T downgrade my bootloader anymore, even flashing -11, marshmallow, or any other firmware.. Strange

Possibly to prevent users from downgrading and opening up the security vulnerability that was patched in the May 2017 security update. https://alephsecurity.com/2017/05/23/nexus6-initroot/ https://www.xda-developers.com/moto...a-root-shell-patched-in-mays-security-update/
At any rate, seems that other users trying to downgrade their bootloader from B1:06 hard bricked (and the blankflash we have doesn't appear to function). Be careful.

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.

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.

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.

I'm just curious to know what happens if we flash an old blank flash.

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.

What firmware for XT1681

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.

In few words we only can flash ROMs with the same compilation number or higher to avoid hard brick right?

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).

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.
