[NOOB GUIDE] Unroot/Relock Bootloader - VZW Developer Edition Moto X

It took me about two days to figure out how to unroot and relock my Moto X. Figured I'd create a total noob guide for those who are also looking to do the same. This is for the Verizon Wireless Developer Edition Moto X ONLY! I have no clue if this will work for other variants like Sprint, AT&T, T-Mobile, etc. So just play it safe and don't...
I've unrooted and relocked my VZW Dev Edition Moto X twice using this method, so as long as you follow the steps below you should be fine. Also please note that I'm not at all responsible for anything that happens to your beloved phone.
Btw, this process wipes your phone completely clean, so back your sh** up.
So here goes.
1. You need a Windows PC.
2. Download and install the Motorola Device Manager (USB Drivers) to your PC. This will allow your Moto X to be recognized by your computer.
3. Plug your Moto X into your PC and let the drivers install automatically.
4. Download and unzip the VZW Developer Edition Factory Image for the Moto X to your desktop.
5. Download both the fastboot.exe and AdbWinApi.dll files and place them in the folder you just unzipped in step step 4.
6. Now grab your Moto X, unplug it from your PC and power it off. Once powered off, press and hold both the Power and Volume Down buttons for about 10 seconds or so to access Fastboot mode.
7. Now, back on your PC, open the folder you extracted on Step 4. Hold down the Shift key on your keyboard and Right Click on an empty space within that folder. From the menu that pops up, click on Open command window here. A command prompt window should open. Plug your phone back into your PC.
8. In the command prompt type fastboot devices to make sure your X is being detected. You should see something similar T0620059GA. If you don't see it, then you may have to reinstall the USB Drivers from Step 2.
9. Once your X has been detected by your computer, and while still in Fastboot mode, type the following commands (in the order shown) into the command prompt on your PC:
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
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 cache
fastboot oem lock
fastboot reboot
...
That's it! You should now be locked and unrooted; back to the out of the box factory state. Don't forget to hit thanks and share!

Did re-locking ur bootloader get rid of the Bootloader Unlocked Warning Message?

Just to make sure we're on the same page here, after re-locking ur bootloader, when u boot the phone, u get the Moto logo instead of the message that says Warning Bootloader Unlocked?
Because many other users said that u would still get this message even if u re-lock ur bootloader.

When I relocked the bootloader and rebooted the phone I didn't get the warning message. Went straight to the Moto logo. But then I immediately rooted and unlocked again. Only reason I unrooted and relocked in the first place was because I flashed a zip file that corrupted and broke Google Voice Search on my phone.
The second time I did this process I stopped right before locking the bootloader since I was going to root again anyways.
So maybe those other people are right. I've only rebooted my phone once since relocking the bootloader.

If you want to get rid of the warning on startup, just flash the logo.bin. You can do this and remain unlocked. The instructions provided should have your phone looking and acting the same as it did out of the box. However, fastboot may note that it's been unlocked, to the OP, do you recall what status fastboot was reporting?

you need to reflash to stock in order to lock your bootloader? If not, I would appreciate if you separate the steps to just lock your boot loader.
I have my boot loader unlocked and the only reason I am considering to lock it again is so that if the phone is stolen, someone can't reimage it easily. I'm not sure that gives me any sort of protection though. But its just a thought.
In other words, I see unlocking and locking as a switch that stops you from flashing firmware. The OP makes it sound like the switch is tied to the firmware, ie only stock can have bootloader locked. I am not sure which is right.

I have no clue. At first I just flashed back using RSD Lite. Then I ran the lock command and got that error. Afterwards, I searched online, trying a bunch of different fastboots. That's when I stumbled on this list of commands, figured I'd run it from scratch, see if it makes a difference. Once it got to the relock command though, I got the same issue. And now I'm just frustrated...

Yes Sir..with Kit Kat 4.4..I have successfully"Unlocked", "Relocked" and "Unlocked" again..my XT1080MDEV (Droid Maxx)..No one could tell me exactly how to do it..Motorola Tech Line was absolutely NO HELP either..SO..after hours upon hours..I did figure it out..Now I'm working on "Relock" on JB 4.2.2
Sounds easy..and many have probably "Unlocked and "Relocked" on JB 4.2.2..BUT..The difficult part is once the XT1080 has been on KK 4.4..is when alot more firey hoops must be jumped thru..
ANYONE can chime in with help on this..NOT ADVICE..but proven procedures..

[Q] bootloader issues

So a while ago I rooted my phone but messed it up because I uninstalled a few too many system apps. I just dealt with it for a few months since I could still make calls (but not much else). I finally bit the bullet to look into flashing the stock rom again, but to do so it looked like I had to install a custom recovery, but to do that, unlock the bootloader. So I first unlocked the bootloader using motopocalypse (batch file didn't work but apk did), and got the expected BOOTLOADER UNLOCKED message at bootup, with fastboot saying unlocked, code 3. I then tried flashing CWM recovery via Rom Manager, and it seemed successful, but I was unable to boot to it either from the UI of ROM manager or from holding the buttons during bootup, it would just hang for a few more minutes than normal at the BOOTLOADER UNLOCKED screen, then boot up like normal. So I kept reading, found RSDlite, and was able to flash the stock rom, which I downloaded from the internet and the phone boots up fine, but now fastboot says locked, status code 2, and motopocalypse does not unlock it again (either the batch file or the apk), but I still get the BOOTLOADER UNLOCKED message at bootup. So I'm not sure if my bootloader is unlocked or not and if I can proceed with installing CWM recovery again, so i can make a full backup in case I mess something up again.
So how do I reunlock the bootloader, or verify if it's locked or not?

First, CWM and TWRP aren't official for this phone, so you can't use their apps to flash. You'll need to use fastboot, Flashify, or Rashr. Second, you're still unlocked, we've seen this error come from bad flashes. What is the complete text on your FB screen. You should be able to clear this by re-flashing with RSD. What firmware did you attempt to flash?

I think your boot loader is still LOCKED. Mine is showing UNLOCKED. Status code: 3. You cannot flash a custom recovery on a phone with a locked BL. You need to motocalypse again!

To trace the issue from the ground up, if you're just trying to reinstall stock ROM, you should be relying on RSD instead of trying to mess with custom recoveries and BL unlocking. Just flash .10 (not .15) via RSD, root via Towelroot and you can start fresh.
Unlocking your BL is still highly recommended, though, 'cuz it's now or never.

Yes, that's why I'm asking. So I've got one vote for unlocked, one for locked. As I said though, motopocalypse isn't working a 2nd time.

I would like to flash custom ROMs later down the road, but for now I just want to get the stock stuff going.
On a side note, the version of the image I downloaded was 183.x.x, but my mother, who has the same phone, purchased at the same time, and has never rooted it or anything, has version 182.something, and that is also the version I had before I started messing with the bootloader/recovery stuff. The two versions were released at the same time, but I don't know what determines which version you got if you just did OTA updates, or if it even matters. Speaking of OTA updates, the version I downloaded is prompting me to do an OTA update now to another 183.x.x version. I wonder if I'd be able to grab the 182.x.x ROM from my mom's phone without rooting it via fastboot or something.

The 182/183 does not matter regarding root/boot loader unlock its the .10/.15 that matters do not take the .15 without unlocking your boot loader....
We cannot teach people anything; we can only help them discover it within themselves.

So no other thoughts? What would happen if I flashed a custom rom/recovery with a locked bootloader? I tried flashing the ROM again and fb still says locked, code 2, and motopocalypse still doesn't do anything like it did the first time.

It won't let you flash a custom recovery. This is the difference between locked and unlocked.

If your bootloader is relocked for some reasons, try unlocking it again with
Code:
fastboot oem unlock

I guess what I'm asking is, will it let me flash it but then the phone won't work or will give an error on boot, or perhaps brick my phone? Or will it just not flash in the first place? Because if it's the latter, then I can just try to flash a custom ROM/recovery and if it works then I know it's unlocked.

Still locked code 2 though. Looks like it wants an unlock code from Motorola's website, I tried following the steps to get the code but it says I'm not eligible for bootloader unlock. So unless there's another way to get the unlock code...

A "Code 0" locked device would refuse flashing an unofficial or older recovery. I have no idea about Code 2 though.

From what I was able to locate status code 2 indicates that the bootloader has been unlocked and relocked like by doing the whole "fastboot oem unlock unlock code" then the "fastboot oem lock" ... I'll look more into it but from what little I read it looks like it can not be unlocked again with out the Motorola unlock code...

Same here, I can see what it means but cannot find any way to get back to code 3 other than using the unlock code from Motorola, which I am unable to obtain because it says I am not eligible. Surprising that someone hasn't cracked the unlock code yet or made a keygen, people are so eager to do it with pirated computer software before the software is even released.

I've read of someone getting locked status code 2 b4 from flashing an older gpt with rsd (if I remember correctly) I think all that was required to fix it and get unlocked again was to flash the latest gpt. Very important..... Are you sure when you were unlocked you didn't ota update to .15? Because flashing .10 gpt while on .15 may be what caused your false relock

Nope, no OTA update to .15. The ZIP I have of the rom does include the gpt.bin file with the same timestamp as all the other files. I suppose I could try reflashing the whole rom once again later...

Hmm strange, I went to find the old thread I read about the gpt relock issue but it's not exactly the same as your situation.
http://forum.xda-developers.com/showthread.php?p=51436123
Until now I didn't think relock was possible due to the way unlocking works. It's a physical change, a qfuse was blown when the motopocalypse apk was run the first time. It can't be unblown lol. Wish I knew what went wrong here.

[Solved] How to Re-lock Bootloader and go back to stock?

Hello,
I want to relock the bootloader and go back to stock.
I tried flashing stock firmware using fastboot.
fastboot oem lock begin
flashed stock firmware
fastboot oem lock
But Bootloader is still unlocked.
I got message as first flash full stock system. Something like that. Don't remember as I tried this a week ago.
Any help will be highly appreciated.
Thank you in advance.
Edit : I also tried the Windows tool provided by one of the members but it failed too.
I used the same to unlock in the first place.

I think it depends on what you want to achive. While you might be able to re-lock the bootloader (which means it can't be flashed without being unlocked again), you will never ever get rid of the unlock message again. This - to my understanding - is an efuse which is permanently set. If you want to remove the unlocked bootloader boot message, I'd stay unlocked and would just flash a different boot logo (logo.bin) where the unlocked gfx are replaced with the standard gfx thus showing the standard boot logo.

I would like to relock the bootloader altogether.

I don't think you can. You can lock it but you can't remove the warning that it has been tampered with.

I don't care about the warning.
I just want to re-lock it.

Flashing the Official firmware for my Country - India did the job.
Last time I tried with firmware for ASIA.
I don't see any reason for that to fail but you never know.
Thanks for replying.

hey can you give me the link for that rom im also using the indian version but unable to lock the bootloader

OnePlus 2 locked bootloader issue

Before I describe my issue I'll let you know I've been looking up articles on how to solve this for weeks now. first post to XDA, so bear with me I'm new
I have two OPT, both have a similar problem, but one is working (I dare not try to mess with it) and the other I've already tried and tried and now I'm stuck in fastboot, no recovery, no OS.
I HAD an OS on it (Paranoid Android 6.0.1), but I couldn't factory reset, and I needed to, so that I could sell the phone. when I tried to factory reset through OS settings, it would boot loop until I hard reset the phone. I had no recovery apparently (IDK how I did that) but trying to install a recovery requires the "OEM Unlocking" setting to be checked. and for some reason it won't let me check the box. My working OPT phone has the same problem, the "Allow OEM unlocking?" box pops up, I select enable, and the toggle moves itself back to the grayed out selection. so I couldn't install a custom recovery, I can't do any formatting or erasing in fastboot either without that selection for some reason either. trying to only gives me a "FAILED (remote: device is locked. cannot erase images)" or "FAILED (remote: device is locked. cannot flash images)"
AND SO, I tried this (search google for "mega unbrick guide for a hard bricked oneplus 2". I can't post links apparently as it is my first post. it will be on the oneplus website) and now I have no OS. or at least I believe I have no OS because trying boot causes a bootloop. I've tried all the methods, but I'm assuming because my bootloader is locked, It failed with the "A2001_save_brick_mini" tool.
And so, all I have right now is bootloader. didn't have a recovery I guess, and now I think I don't have an OS. and I can't do anything in fastboot because is returns with a "FAILED" hehe. dang locked bootloader. I have no idea how both of these phones have locked bootloaders anyways, because I obviously unlocked the bootloader to install a custom ROM in the first place. did the bootloader relock itself, or maybe during the process of installing the ROM, the bootloader relocked? I'm not sure as I wasn't watching for that. the phones had booted with the new OS, and so I happily went along my business and didn't find out I had a problem until I tried to factory reset one of them.
no I have no phones now with similar problems, but at different stages of the same issue.
My ONE A2005 is working, but I can't toggle the "OEM unlocking". At least it has a working custom recovery (TWRP)
and MY ONE A2003 is stuck in fastboot (fastboot recognizes it via "fastboot devices" and I can reboot and "fastboot oem device-info") with what I believe to be no recovery or OS.
ask me any questions to further explain my predicament, and PLEASE offer me any things to try. I ave two phones to test different things with. I would prefer to keep the working one working though.

Ah yes, I forgot to write that in. That also results in a "FAILED (remote: unlock device to use this command)"
I can't unlock because of the OS, or perhaps lack of OS now; And I can't install a new OS or recovery because my bootloader is locked

use qualcomm recovery tool if you can't get any help. it'll restore your phone to 100% stock

Relocking of bootloader

I wanted to relock the bootloader of my Moto G4 Plus as now I'm in no need of root now. And even want to remove the logo which says my bootloader is unlocked.. I used the code but it is not working still pls help me out

i think you are in the wrong section but nvm. for removing the annoying boot logo you can flash the logo bin
Code:
fastboot flash logo logo.bin
in fastboot mode where "logo.bin" is the filename.bin. you can find the logos at this link
https://forum.xda-developers.com/moto-g4-plus/themes/customized-logo-t3451349
or if you want some more cooler ones just search around.
Now comes to relocking bootloader, you must give more info(what phone you are using) and from where you got the link and what commands you pressed. you can follow this link which uses dec update or (if you check last messages even the feb update though i would recommend dec)
https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
