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 seem to have lost the ability to unlock the bootloader of my XT1700. I previously had unlocked the bootloader and installed TWRP and SuperSU, which took a while to figure out, but it worked. Today I tried to install a newer version of the stock firmware using SP flash tool (from here), which seemed to work fine, except now I find I am unable to reinstalled TWRP or SuperSU because I cannot unlock the boot loader.
When the phone boots, I still see the "device unlocked" message, and I have enabled oem unlocking and USB debugging in the developer options menu, however when I go into fastboot mode, if I run the "fastboot oem unlock" command, when the phone prompts me to press up or down, I get an "unlocking failed" error, and Fastboot reports "Unlock operation is not allowed"
Any ideas on how I can unlock this device again?
So it seems like those firmware images must have locked boot loaders. I ended up installing an xt1706 firmware instead (from here) and was able to unlock the boot loader successfully.
Anyone know where to get xt1700 stock firmwares with unlocked boot loader?
Hello i have a J7 Sky Pro sm-s727vl popqltetfnvze. In developer options I have the OEM Unlock switch. I have also ran crom service and it says that I can now install custom os. Is it unlocked?
Really no comments
Crom service doesn't work on this phone, that's why the app reports it's already unlocked, the phone's bootloader is locked, but not by crom.

When you try to flash anything modified using Odin the "secure check failed" error you see on your phone screen means that the bootloader is locked.
Hi,
Hello
My phone is a xiaomi mi a2 of 64
The problem is:
After blocking the OEM with the "tool all in one", my phone issues a warning "your device has loaded into a different operating system" and then shows "the software device can be checked for corruption, please block the bootloader"
Is there any way it works normally?
You locked the bootloader with an uncertified/modified version of Android.
Unlock your bootloader (oem unlock, flashing unlock, flashing critical unlock), flash the stock ROM and then you can lock it again.
Flashing unlock is no allowed

When I try to do that I get "flashing unlock is not allowed" try the various tools that are on the platform and writing them manually, I get the same.
How could I unlock it?

Hello all! I have been trying to unlock my bootloader on my SGP311. I have searched the threads, followed the instructions, and still have problems. i initially looked at my service menu to determine if it is unlockable and it said yes. I then went through the steps to unlock it and it kept saying failed. Then, it finally worked, and my tablet rebooted. i got dual recovery loaded and then proceeded to wipe and install lineageOS from recovery. recovery kept failing to install the new rom. i then had to reflash a stock rom because the tablet wouldnt even boot into recovery again. now my service menu simply says rooting status: unknown and says nothing about the bootloader. What the heck happened?

You can't install LOS Rom from the dual recovery (XZDR). By flashing stock ROM, you bootloader may be locked again.
Check this guide to unlock it, and install LOS.
It simply will not let me unlock the bootloader anymore. And I can't seem to find a firmware that I can flash to get me to the appropriate version
so far, part of the problem is flashtool in androxyde still using the command fastboot -i 0x0fce oem unlock 0xkey. windows 10 denies this command every time and should be fastboot oem unlock 0xkey. But even doing so manually through the cmd prompt, it still will not let me unlock the bootloader. does anyone have a ftf file that has an unlockable bootloader? seems mine locked up completely when i reflashed the rom

bootloader is in device, not in firmware, so no such firmware exist you ask for.
