relock bootloader
=============
keep in mind this will remove any and all personal files and settings
like any self respecting android user you have made backups right....!!!! GOOD

download adb and fastboot extract or place into a directory.
now download the factory firmware image of your phone extract zip/rar and place into the same directory.

download "relock bootloader.txt" rename to "relock bootloader.bat" place this in the same directory as the files and double click it ,this would save you typing in all the commands from below in by hand and does it all for you.recap....if you did download and run relock bootloader.bat you dont need to type anything form below

open a command prompt as administrator ,navigate to the directory where you placed all the files we are working with and type as follows giving time for each command to finish.

fastboot oem lock begin
fastboot flash partition gpt.bin
fastboot flash motoboot motoboot.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 modem NON-HLOS.bin
fastboot erase modemst1
fastboot erase modemst2
fastboot flash fsg fsg.mbn
fastboot erase cache
fastboot erase userdata
fastboot oem lock

NO this didnt help me.. Even bricked my device..

you can brick your device if you flash the wrong firmware, from another device like moto g 2014

Unlocked bootloader?

Okay so I unlocked the bootloader on my phone, and was having some issues, so I relocked the bootloader, and now my phone is working well again. However, when I get the unlock data from the code (The ridiculous string of digits and letters motorola likes for some reason) The page tells me that my device "No longer qualifies to be unlocked." Is there a way to remedy this? Thanks in advance.

No, you can't change it back, now.

It is getting that because once the thing was unlocked, a flag in the phone is permanently set that cannot be changed back. If the phone is rooted you can reflash that message image file so the message goes away, but since part of the relock was to reflash the factory image (which is an unrooted image) you can't do that now.

All you can do is unlock it again with the phone's key, root it, then reflash the message file. But, once the phone is activated on a new account it will eventually do an OTA update that will replace that message image file and the message will start appearing again.

Here's more info on the specific software flags used (qualcomm calls 'em fuses)

Also, it's the logo file you would flash to make the message go away.

fastboot flash logo

I do not think it will stick during an OTA update, though.

After using CM13, i reverted to stock 5.0.2 by using this thread:
http://forum.xda-developers.com/showthread.php?t=2700502.
I used the option WITH re-locking and the "Unlocked Bootloader Warning" screen appeared during boot )-:

So i unlocked again and flashed the "nice" logo.bin: http://www.droidviews.com/remove-unlocked-bootloader-warning-on-moto-g-moto-x-purestyle-using-fastboot/

In that state I successfully received an OTA update to 5.1, followed by another OTA update with a small patch (10 MB size). The phone remained unlocked after the OTAs - and the "nice" logo is still there.

I will keep it this way. The phone is older than 2 years anyway.

P.S.: Later I found, I could also have updated to 5.1 with the PC per http://forum.xda-developers.com/moto-g/development/rom-stock-motorola-lollipop-rom-t3017510, applying the same procedure as for the 5.0.2, but re-locking seems to trigger the bad logo.

Hey, I had the same problem...but when I tried the commands given by akaygee, in the end after "fastboot oem lock", the command prompt again asked for begin with "fastboot oem lock begin", afterwards it asked for signed images without which it cannot lock, so is there a way to get moto signed factory images
