Relock Bootloader in Nougat

Hi, Here is my issue: I have the xt1625 and i downloaded an OTA nougat software from india NPJ25.9 (7.0). It worked great, then i unlock my bootloader to install cm14. The problem began when i wanted to revert back to the official Nougat, i was able to come back but the .bat file that came with the Stock Rom didnt have the option to relock the bootloader so i tried downgrade to mm to lock it with the fastboot oem lock begin and fastboot oem lock, However it didnt work.
The mfastboot said bootloader pre verification failed and never locked, so i went back to nougat which i am running atm. the problem is i still am with unlocked bootloader and i see a change in the warning screen instead of n/a it says bad key.
another problem i see is during flashing some of them return (bootloader) image signed with key bad key

And the lock never happens. it says at the end: flash a valid android image and rerun the comand.
Does anyone have a solution for this? can the bootloader be locked with nougar rom, if so, should i edit the .bat file? and how? i tried edditing the .bat file but dont know how. does the ''bad key'' message means something wrong?

my problem is the guy who posted the nougat rom did it with a .bat file but didnt include the lock comands, and i dont know how to add them. do you have the .bat file or bloc comands you can share?

I used the firmware which is available on russian lenovo forum.
The error has something to do with your firmware.

I did not. The nougat firmware I installed had a bad signature key and I could not relock because of it and downgrading did not help because boot loader cannot be downgraded. I have to wait for a newer nougat firmware with not bad key Signed to lock. I have npj25.99-11 so I have to wait for newer version.

Hopefully not too long a wait - is 99-11 the latest build from Moto? Haven't seen any firmware updates captured yet.

Same here...
I flashed a Nugat rom last night and ran into the same issues. I'll be eager to flash again once a new rom is available.

Same, but when I run the commands to lock the bootloader, the phone stays at "bad key" forever ( no warning message only a black screen with "bad key" on it) and i have to flash the rom without the lock commands for the phone to boot. And I'm also getting those errors.
Mine is XT1641

Old thread, but same problem here. I can't get the phone to boot no matter what now. I tried out this link: https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-xt1640-43-athene-npj25-93-t3549369
Everything is normal up to running the `fastboot flash boot boot.img` and then it complains `(bootloader) Image signed with key bad key`. The phone refuses to boot no matter what now. Any advice on how to fix it?

Please help - official OTA Nougat update has left phone in boot loop

Hi, I recently downloaded the OTA Nougat update for the Moto G4 phone but instead of completing the process it showed the android man on his side suggesting something went wrong. I tried to restart the phone and it would not boot up, instead being stuck in a boot loop. I have read many videos in an attempt to try and get the phone working again on stock firmware but everything I read seems to have the requirement that USB debugging has been enabled in the Developer settings.
Unfortunately this was not something I enabled as I did not envisage there being any kind of problem with the update as it was the official OTA update of Nougat. I have downloaded what I believe to be the official marshmallow stock firmware for my phone which is the athene_13mp XT1622 16gb P2A variant but I can't figure out how I can install it. When on the bootloader screen on the phone, when I type 'adb devices' on the command prompt no device is listed, however if I type 'fastboot devices' it does list the serial number of my phone followed by the word 'fastboot'. Could anyone be kind enough to point me in the right direction of what I can do from here (if anything). I tried a live chat with someone from Lenovo support and they were absolutely useless.
Apologies if this is answered elsewhere, I tried a search and couldn't find anything to help me.
Thank you

First of all, "adb devices" doesn't work on the bootloader. The adb app only works in recovery or while booted into the system. Secondly, is your bootloader unlocked? How you proceed depends on that. If you still want to install Nougat there are a couple of options. Let me know your current bootloader status. Above all, don't panic and do something rash.
Here is a link to your phone's stock firmware" https://www.filefactory.com/file/5c...24.139-23.4_cid50_subsidy-DEFAULT_CFC.xml.zip

Hi, thank you for your reply. On the bootloader screen it says :

Not sure if you need all the info, the only thing I left off was the serial number as I don't think you need that. As you can see the OEM is locked and as I can't boot up the phone I don't know another way to unlock it. Just an update to this as well. Since my original post I followed a guide on YouTube to try and use something called 'Minimal ADB and Fastboot' and it seemed like it was running through the process of installing all the files as lots of data was passing through the CMD window but when it finished the phone just went back to the green Android man fallen over with 'No command.
Thanks again for any help you can ofer, it is really appreciated.

Also thank you for the link to the firmware, I just checked and this is the same file that I already downloaded so I do at least have peace of mind that I selected the right one.

Your phone is probably fixed already. Try to boot with Vol- pressed to enter the bootloader and then select the option that boots to system (not recovery). Recovery screen with "no command" simply means that the "boot to recovery" flag is set and there is no OTA file in phone's memory. After booting once selecting the correct option in the bootloader screen your phone will be back to normal.

Hi, thanks for your reply, sadly I have tried all the options from the bootloader with no success, they do the following:
START - tries to reboot (white screen with blue moto logo) and eventually comes back to android man fallen over with 'No command' underneath
RESTART BOOTLOADER - Just takes me back to the same bootloader screen immediately
RECOVERY MODE - Takes me back to android man fallen over with 'No command' underneath
POWER OFF - turns it off (obviously lol)
FACTORY MODE - tries to reboot (white screen with blue moto logo) and eventually comes back to android man fallen over with 'No command' underneath
BARCODES - displays white screen with four barcodes relating to IMEI, SKU, DATE and SERIAL NUMBER
BP TOOLS - tries to reboot (white screen with blue moto logo) and eventually comes back to android man fallen over with 'No command' underneath
QCOM - tries to reboot (white screen with blue moto logo) and eventually comes back to android man fallen over with 'No command' underneath
BOOTLOADER LOGS - Doesn't do anything when I click the power button on this option but shows some yellow text on the screen that says 'Fastboot reason: Volume down key pressed'
That is all the options I have then, none seem to resolve the problem.
Thank you

Also, I'm not sure if this is relevant but when I ran the flashstock.bat file to try and install the files from XT1621-XT1622-XT1642_ATHENE_MPJ24.139-23.4_cid50_subsidy-DEFAULT_CFC.xml, I noticed as the text scrolled up the CMD window that there was several mentions of:
slot count not found
slot suffixes not found
has-slot system not found
invalid signed image
These lines appear several times, I'm not sure if this is part of the problem or not. If the CMD window didn't automatically close I would have copied and pasted exactly what it says.
Thanks again

Open a command prompt instead of double clicking the bat file. Also make sure you have motorola adb drivers installed, or use motorola's flash tool, RSDLITE, instead of flashing with the bat file.

TRY THIS BEFORE DOING ANYTHING ELSE: Boot to recovery. While at the dead robot, while holding down the Power key, press and release*the Volume Up key, then release Power.. This takes you into the actual recovery menu. scroll to "wipe data/ factory reset". Then do a factory reset and reboot. It may go ahead and complete your attempt to install Nougat.
[/B]When you are at the bootloader, do you still get your device serial number at the command "Fastboot devices" from your pc? If so you can unlock your bootloader if you so desire. Link to unlock instructions: https://motorola-global-portal.custhelp.com/app/standalone/bootloader/unlock-your-device-a
If you can't get flashstock.bat to work then you can flash your stock ROM. in the sequence below. You will need to extract the ROM to your PC and follow the instructions below:
fastboot oem fb_mode_set
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash system system.img_sparsechunk.5
fastboot flash modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot oem config carrier vzw
fastboot oem fb_mode_clear
Also, you don't ever need to share your serial number. Finally, the baseband shown is the original Marshmallow stock baseband which tells me that your attempt to flash Nougat failed.
If you have doubts or questions ask first.

Hi, thank you for your reply, I just downloaded and tried the RSD Lite software. It detected my phone on Port number 1 as 'Fastboot athene_13mp S' and I selected the 'flashfile.xml' and pressed start. Unfortunately it stopped with the status 'Failed flashing process. 3/27 flash partition "gpt.bin" -> Phone returned FAIL.' Does anyone know how to get round this?
Thank you

Did you manually flash the fastboot images in the sequence provided?
If that doesn't work, I would send it back to Motorola. If it isn't in warranty, well, rip.

I do still get the serial number when running 'fastboot devices', do you think unlocking the bootloader might be the answer? I went through te steps yesterday to get the code, was a little put off by voiding the warranty though. With regards to running the commands one at a time, I think I am now getting a bit confused on the correct procedure of where to run the commands from. I have tried running it from the folder for 'Minimal ADB and fastboot' (this folder contains all the files from the stock firmware folder as well which I copied and pasted in there) and also directly from the stock firmware folder itself. I will paste the results of each below (sorry to confuse the issue, my head is fried now, lol).

I stopped after the second line as the text above suggests to me that part has failed so no point continuing. When running directly from the firmware folder I get the following :

Again this seems to fail also but with some slightly different messages. Interesting that it failed on the gpt.bin part as this was also mentioned when it failed on RSD Lite.

If the firmware is Android 6 and you at some point flashed Android 7 (or tried to), then its safe to edit the .xml file and remove the reference to gpt.bin, and start the flashing proccess again. This error happens when you try to downgrade the phone firmware.

Yes this whole problem started when I used the phone to check if there were any updates. It said that the Nougat update was available and so I downloaded it on the phone and pressed the button on the phone to install it. This then failed and was the start of all my problems.
I have edited the 'flashfile.xml' file and removed the line <step MD5="e12b1a18da98b9502c735ce6ca192217" filename="gpt.bin" operation="flash" partition="partition"/>, however, it then failed with the message 'Failed flashing process. 5/26 flash boot "boot.img" -> Phone returned FAIL'. Any ideas please?

As long as you can still access the bootloader there is still hope. Did you go through with the entire procedure to unlock your bootloader? If so, can you flash a custom recovery such as TWRP 3.1.0? (fastboot flash recovery "name of the recovery file") After you have done that you can flash any custom ROM you desire.
Also, I suggest you take some time to read through the forums for both the G4 and the G4+. It is obvious from your questions that you haven't done so. There are solutions posted that WILL work for you but you MUST take the time to research and read. Doing so will save a lot of time and keep you from bricking your phone.

AFAIK, this one isnt safe to skip.. Im out of ideas, sorry. Try another usb cable just in case.. but if it keeps failing at the same point you will probably need to send it to motorola service.

As long as you can still access the bootloader there is still hope. Did you go through with the entire procedure to unlock your bootloader? If so, can you flash a custom recovery such as TWRP 3.1.0? (fastboot flash recovery "name of the recovery file") After you have done that you can flash any custom ROM you desire.
Also, I suggest you take some time to read through the forums for both the G4 and the G4+. It is obvious from your questions that you haven't done so. There are solutions posted that WILL work for you but you MUST take the time to research and read. Doing so will save a lot of time and keep you from bricking your phone.

Hi, I did not go through the entire procedure to unlock the bootloader because I'm not sure that I can. Every guide I have read about this says about enabling developer options so that I can 'Allow OEM unlock' but I can't do that if I can't turn the phone on .
This is how far I get (I removed the actual unlock code as I don't know if that should remain confidential):

If a redownload of the stock images and a new USB cable and flashing of the images doesn't work, I'd just send it back to Motorola.

You may be right. He has not successfully unlocked the phone so therefore his warranty should still be good.

I don't understand why you can't flash the stock ROM. Your baseband version is still on stock. That said if you want to continue trying give this a shot: https://forum.xda-developers.com/moto-g4-plus/how-to/xt1643-ota-nougat-t3483943 This will bring you up to Nougat the latest release. It does not require an unlocked bootloader and has been used on your model.
Or here: https://forum.xda-developers.com/moto-g4-plus/how-to/xt1644-stock-marshmallow-to-nougat-t3540022
Otherwise I would go ahead and do a warranty return. Your warranty should still be okay since you did not go through with unlocking the bootloader.

Help, my Moto X Style XT1752 Brick :(

Hello people, I come with a Moto X XT1572 brickeado, out of nowhere is stuck in the Motorola logo and it does not pass from there, restarting over and over again.
I tried several methods to try to install a stock Firm, 6.0 or 6.1, but without success.
Because I can only connect it in fastboot mode and RSD Lite does not recognize it, I followed the tutorial:
https://www.youtube.com/watch?v=njXQYn53SPc
Whatever Firm it is, I throw the following error:
Fastboot flash boot boot.img
(Bootloader) has-slot: boot: not found
Target reported max download size of 536870912 bytes
Sending 'boot' (40960 KB) ...
OKAY
Writing 'boot' ...
(Bootloader) Preflash validation failed
FAILED (remote failure)
Finished. Total time: 2
I understand and I have read, the problem is initially in the boot, I have tried flashing only the boot, but it does not respond, throwing the same error.
It is worth clarifying that the bootloader is blocked, and if I try to unlock it it throws me:
(Bootloader) Check 'Allow OEM Unlock' in Developer Options.
FAILED (remote failure)
Finished. Total time: 0.00s
I can not check that option, since it does not fix je.
Also it is worth clarifying that it does not allow me to enter the recovery, when it enters that option it is automatically restarted returning to the motorola logo again and again.
Do you have any idea what else to try? Thank you in advance.

Have you tried a factory reset in the stock recovery? From the bootloader select Recovery and let it start, when you get "Dead Andy" with an exclamation mark after the timeout, hold power and tap Vol Up and release both keys. Select Factory reset/Wipe data and let finish and then reboot... First boot can take 20 minutes plus after a reset.

Stock firmware images are digitally signed, so yes, you can flash them with a locked bootloader., but downgrading is tricky even with an unlocked bootloader. The key here us to just get it bootable.

Good afternoon, I return the subject after a long time since yesterday I thought to try again, and I found that the cell now turns on, but when trying to complete the initial configuration, after choosing the language gives me to select the wifi networks, where it does not detect any, and I do not enable the jump or forward button, and I'm stuck there again, it's very strange, as soon as I enter that screen, it gives me the option to add a new network, and I can see that says Mac Address with pure zeros, as if it did not have MAC.
If I try to enter the recovery, now I see "No Command" (previously not directly entered), and there is no way to skip this "No Command", I have tried all the methods that appear online.
EDIT: I was able to get into recovery, but I do not know if it can help me now.
Any ideas? he seems to be brigado, but not as much as before

Flash the right modem for your region in fastboot. You should repeat the fastboot command "fastboot flash modem NON-HLOS.bin" at least two times because the first time it won't "stick". After you'll have to execute "fastboot erase modemst1" and "fastboot erase modemst2" commands and your wi-fi and data signal should return.

I still have a problem, when the device is turned on, it always turns on Bootloader mode, and I have to select "Start" to turn it on. This is why when you want to upgrade to Android 7 via OTA, when the device is restarted during installation, it enters Bootloader mode, select "Start", restarts the update, restarts in Bootloader, and remains in an infinite cycle.
Is there a solution to this? I have already activated USB debugging in order to unlock the Bootloader.
Thank you!!

moto g4 play stuck in bootloop after official motorola update.

Hi, i updated my moto g4 play (xt1602) to the android update in india. Unfortunately it is in bootloop and wont start to lock screen. Oem is locked and usb debugging is disabled. developed options also not enabled. i used LMSA (Lenovo moto smart assistant) to recover it by flashing original firmware but it is still in bootloop. i have searched on google and forums and found that due to these i.e.(Oem is locked and usb debugging is disabled) i cannot flash any recovery and cannot install any rom through fastboot. Also "adb devices" command does not recognise but "fastboot devices" command shows serial number of my device. i also got oem unlock code from moto website but it said remote failed for "oem unlock" command in fastboot.
(Also i was wondering is there any way that i can edit oem.img and bootloader.img file in official firmware that LMSA downloads and flashes in the device and can that unlock the oem and bootloader )
Is there any way to recover the device or is it bootloop bricked to eternity.
Note: i had my screen replaced and after that i did the update. can it be the issue. (i' ve kept the old broken screen module, can it help recover the device if it is connected.)
Thanks in advance

It seems your trying to flash a old version of the stock rom try with different one with a latest stock rom and then flash bootloader with same version you have in your phone then try to flash full stock

How can I get the version that my phone already have? I don’t remember what it was before the OTA (and then the brick)

When you don't know on what firmware you were nobody else can. Where do you come from?
If it's India or Brazil the 92-14 build should be safe as it is the latest available so you can't downgrade.
If you're from Europe/US etc the 93-10 build is the latest available. You find both here:

I get that error with minimal adb, use this system wide version, never failed me:

Also, make sure you installed moto drivers:

The first set of outputs (slot-count:not found and slot-suffixes:not found) is no failure.
It's just that Minimal ADB and Fastboot is checking if you've got a device with two slots like the Pixel devices with their A/B architecture. I get them too every time I use it. The failure message is supposed to be after that and is most probably the same like
Code:
C:\adb>fastboot oem fb_mode_set
...
FAILED (remote failure)
finished. total time: 0.026s
which is related to the bootloader as you wrote in your first post.
Have you flashed a firmware in the past that was older than the one you were running?
Than your bootloader has been downgraded and when you wanted to apply the OTA the bootloader was not the one the OTA expected.
Have you flashed some stock firmware in the past before applying the OTA?
If yes you have a real problem. In that case I would try to flash a TWRP flashable build:
