Hello, is there any way to check if my bootloader is unlocked? I want to install CWM but i don't know if i unlocked the bootloader correctly, after copying it and writing reboot in adb the phone just turned off. But it did start with no problems after i turned it on after that, and after that i copied the bootloader and it had a different MD5 than the backup i made. Also my firmware is 4.1.2 E61020g-EUR-XX, does it mean i have v20 baseband? I just want to be sure before i flash CM 10.2 because i don't want to brick my phone.
bump. No one knows how to check this? Or maybe is there a way to unbrick my phone if the bootloader is locked and i flash CWM? If there is a way to unbrick then i will just flash it and hope that there will be no brick.
flash cwm and boot into it, if it shows the cwm, the bootloader is unlocked
if it not unlocked, it will show an bootloader security error or something like that
But if it shows the error what will i do then? I don't want to lose my phone.

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've tried reflashing with RSD previously but no change. I could try it once more if you want.
Not entirely sure what you're asking for with the firmware version, but the image I used was for android 4.4.2, version 183.46.10.XT907Verizon.en.US.

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.

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.
I am trying to change my Note 3 (SM-N900K) firmware but first when i try to flash the recovery after the flashing the recovery did not change what should i do?
Thank you
You must unlock the bootloader first!
are there any other application or an easier way to unlock bootloader without rooting?
I am not familiar with the n900k but using an app to unlock the bootloader if the bootloader is not locked will probably brick the phone.
Are you booting right into the custom recovery as soon as you flash it? If you flash recovery and just reboot to the rom, the stock recovery will overwrite the custom recovery.
Long story short. I had an Axon 7 A2017 B11 which I updated to B13. I was able to unlock the bootloader, root the phone then flash a custom rom Z.A.D.Mix7_v0.3. I was having fun with the phone but I did something very stupid when I realised I could not use Android pay due to unlocked boot loader. Without doing enough research, I went to fastboot and did a fastboot oem lock. The command was successful but I could no longer boot into the system or recovery or fastboot. I tried MiFlash with B07 which was posted in this forum, but it did not work, came back an error of bad format. Then I used axon7tool to flash TWRP 3.0.2 and the boot.img which I extracted from B13. I am now able to boot into TWRP and fastboot. But I still do not have a working system. I tried fastboot oem unlock, it does not let me do it. I flash ZAD Mix7 again but once I flash that it does not boot anymore. I am now really stuck. What should I do to go back to stock then start everything again. Thanks a lot for the help.
I understand your device doesn't boot into system anymore, but can adb on your pc detect it at all? If so, you can try following all steps after "B)" in my tutorial. I think your aboot img and fbop partition are messed up. If you can use adb to replace the files in aboot and fbop with files that allow the fastboot oem unlock command to be executed, it should be unlockable again. After that, custom ROMs should boot.

I'm having a similar issue. Although my phone boots to stock rom I seem to have messed up my bootloader. I had TWRP and unlocked bootloader. I, similarly, locked the bootloader and things seemed to be fine. After attempting to install Nougat received from OTA I realized my bootloader is corrupted. When I hold the power and volume up the phone seems to just turn off (or go to EDL mode? I'm not sure) I can always just hold power and it'll boot up normally. Is there a way to get the stock bootloader to work and keep it locked?
I also bricked my A7 after relocking my bootloader. I used tenfar's tool to make TWRP my boot.img, then flashed ZTE's stock B20 image. Here's the thread where I found the file links.
From there I updated all the way up to the OTA Nougat, but I suppose you can decide where you want to go after it's unbricked. Hope this helps.
Why are so many people relocking bl? Regardless, always take an ota before locking to ensure you are completely shock.

No, you do not. I thought that was the case at first as well, but I was mistaken. You do, however, need the stock recovery and an untouched system partition.
My problem is that I don't seem to have a recovery at all. I realized once the ZTE logo pops up I can hold down both volume keys and get to the bootloader. The bootloader is locked but does not display a bootloader version or basedband version. I tried the tenfar tool (axon7root.exe) and now my phone doesn't boot into the system either. I really need help...
Just an update to everyone that helped.
I finally managed to fix it.
I used axon7tool to flash a signed TWRP, so that i can boot into TWRP. The signed TWRP is the only way to make it work. Then I downloaded the A2017 B11 from this thread
https://forum.xda-developers.com/axon-7/development/rom-guide-updates-to-stock-files-via-t3469484
There are two zip files. The boot stack and the rom. Because it is a stock rom, I can boot into the system. The next thing I did was to enable the developer option and turn back on the option to allow OEM unlock.
I went back to TWRP. boot into the fastboot screen. Then I simply typed in 'fastboot oem unlock'.
I went back to TWRP, which says can't read encrypted device. I formated everything. mount the USB then flash the custom rom again.
Hola, phone fixed. Made me sweat for the whole day.
deleted...forgot I had a micro sd card. Flashed stock update from the card and it worked. Phew!
I was trying to flash the stock image and i guess i messed up somewhere because after i did that i locked the bootloder and not it is not booting past the google screen. i want to reflash all images but i cant cause the bootloader is locked. so is there anyway to unlock the oem in bootloader or recovery mode TWRP? i can access terminal in TWRP so any command that can help me?

Maybe try and sideloading the it's through twrp. I can't remember if an unlocked bootloader is needed though. Also, you could maybe try flashing a custom ROM to see if you can boot into it.
I had hardbricked my devices while installing an OTA update and the device was Hardbricked .
I blank flashed the device and it booted and bootloader.
Now the problem starts here.
I flashed the OEM_Lock.bat as I wanted to relock the bootloader. I'm not sure what went wrong but the flash didn't complete and stuck in middle.
The problem remains here is it shows
Fastboot Reason: Failed to initialize partition table
I am unable to flash anything now. Recovery.img fails, bootloader.img fails, twrp flashing fails.
Nothing flashes as Bootloader is locked.
I went to Motorola Service Centre. They also couldn't do anything and simply said that their software doesnt read the phone.
Is there anyone whoe can really help me out with anything left to do?
Any method to force flash recovery, even twrp?
Phone is detected as Fastboot athene_16mp S in computer. It doesnt detect as "Qualcomm HS-USB QDLoader 9008".
What firmware are you attempting to flash?
Your device looks like it's still on the blank flash provided bootloader, which means you have to flash at least the GPT and bootloader. The lack of a serial number and the generic identifier implies you have not been able to flash an actual GPT and bootloader. Also, OEM_locked is normal until you get an actual bootloader flashed over the blank flash bootloader, which usually means trying to flash a GPT and bootloader at least as new as the latest version you had on your device (regardless of downgrades).
I'd suggest downloading the latest Nougat stock ROM we have from here. Do not use any of the scripts at this time.
https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138
Unzip the file, delete any old stock ROMs from your ADB folder and copy over the new stock ROM. Try to flash just the GPT and bootloader then reboot to fastboot. See if you reboot into a fastboot screen with details.
If you do, I would proceed to flash the rest of the new ROM without locking your bootloader. If your device boots then, then you can reflash with the locking commands.
Edit - also, this post probably is better suited to the Q and A section...

The files in mentioned firmware did the trick. It flashed GPT and Bootloader and showed the needed info.:highfive: After that I flashed the same firmware via fastboot commands and device has booted to the stock 7.0 - Bootloader Unlocked. How crazy was I to ignore the proper files to flash? I probably tried 100 times to flash files (wrong once for sure). Thanks alot though for providing the link and instructions. :silly:
Now one last thing, should I flash OEM_Lock file to lock the bootloader so that I can get the lastest Oreo update? I might even think fo selling the device after locking the bootloader. Need your genuine opinion on this as well.

Eh, you live and learn. Besides, you've now got your device running now!
Honestly, it's up to you. Having a locked or unlocked bootloader will not affect your ability to receive OTA updates - you should still receive updates so long as your firmware matches your software channel (and since your device was XT1643, the NPJS25.93-14-18 April 2018 security update should be the correct firmware). At this moment in time, you'll have to use the NPJS25.93-14-18 firmware to re-lock your bootloader - we don't have the stock Oreo firmware at this time. Thus, if you update to stock Oreo, you will not be able to re-lock your bootloader until you can get a leak of the Oreo firmware.
If you're selling, I'd choose to re-lock the bootloader. Else, a potential buyer who is not used to flashing custom ROMs might wonder if there's any tampering with the device (the bootloader unlocked warning, to someone not used to flashing custom firmware, might scare off potential buyers).
Back to Locked Bootloader, complete stock.

I am back to Locked Bootloader as feel the same as you said that anyone buying might get scared by looking the warning sign. Thanks for helping out. :highfive:
Oreo Update via OTA has already started rolling out as per the news I've been reading. I just wanted to see the oreo 8.1 before I sell the phone.
Anyways I got a new device now, Realme C1, 3|32GB as my smartphone usage has declined a lot recently and might remain similar. This device will suffice my requirements.
Thanks for the help and support. :victory:
