[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'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.
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

unlock after relock

several questions in no particular order:
Does the "OEM Unlocking" toggle do anything on the XT1572?
If I issue the fastboot OEM LOCK command after having sucessfully unlocked the device before, do I need to go through the full data wipe+send oem data+flash unlock code process again?
Lastly, I was able to flash the MM firmware for my Single SIM AISA model XT1572 despite having the bootloader locked (I think).
Is that normal that I can flash the official moto firmware using just fastboot without having to tweak with anything else?
I presume that since the digital signatures are correct the bootloader has no issue accepting the MM files.
Not quite the end of the world if I have to wipe everything and start over (it's only been a day) but I regret not knowing earlier. Nor did I expect to get this far with a relocked boot loader. Was trying to add SuperSU and found that while I can overwrite flash the stock recovery I cannot flash TWRP.

As far as I am concerned relocking the bootloader wont wipe your data and yes about the question regarding the stock firmware
PS: Dont relock your bootloader once you unlock it the warranty doesnt come back even if you lock it again

How to Relock Bootloader in MiA1

Hello Guys,
I am trying to relock the bootloader of MiA1 but if I type command- "fastboot oem unlock" then my mobile cause stuck on bootloop. The same thing also happens with AIO Tool.
So please help me if anyone knows how to relock bootloader again? And also let me know whether unlocking bootloader affect warranty or not?
I know one method to lock bootloader that is, you can install stock ROM by mi flash tool but I need to install magisk and that require to unlock bootloader and if I unlocked once then unable to relock again.

The command in fastboot is fastboot oem lock
Have you done some modifications to the stock boot.img file, such as using magisk or something else?

Not sure if I understood correctly, but it seems that you want to have Magisk + TWRP + locked bootloader. That is simply not possible. For locked bootloader you must have stock ROM (no root, in fact absolutely no modification).

Bootloader lock is like a door.
If its open you can put nice things like magisk, root, modification like custom rom and kernel.
Now if you try to relock it it won't lock until and unless you take all the modifications out.
Hope this helps.
If you need technical information just let me know

flash stock boot.img and then probably you will be able to lock bootloader. I have done the same way.

With Nougat i flashed stock image selecting "save user data" and i had bootloader relocked without losing data. Root and twrp were gone. I don't know if it is so with Oreo.

So you need TWRP and Magisk root but want a locked bootloader? That just isn't a possible combination.
To install TWRP, you need unlocked bootloader.
If you need root and TWRP, you need to leave the bootloader unlocked.

You can't have both worlds bro. If you unlock and install Magisk and other stuff, you simply can't relock bootloader. That's why you get bootloop

Some people might say yes some might say no.
It depends on manufacturer.
OEMs don't explicitly say that it won't void your warranty.
So its grey area.
I am going to email Xiaomi about this and update this thread when i get reply.
Had various experiences with unlocked bootloader. So better to follow safe path.
Edit: Called xiaomi helpline two times.
1st said it will void warranty
2nd said it won't.
Emailed them.

That's just what he said it to you. I got two responses.
Support representatives aren't authorised to send you sms or mail.
If there's an issue with your device (Unlocked BL) and you took it to service center. They might say out of warranty due to bootloader unlocking and what would be your reply to that?
Support representatives said it won't void warranty.
You can't back it up with anything since you dont have any proof of that conversation.
So unless it is written somewhere by xiaomi. Words are just words.

Is it possible to unlock the bootloader, root, make some minor modifications (activation of camera api, copying fm radio apk to system folder, etc), unroot, and finally relock (flashing stock boot.img before, of course) ?
I want to have it unrooted because of bank payments, banks apps and streaming TV apps, but I would like to have proper camera and fm radio... Is it possible??

Short answer:no.
Long answer: locked bootloader must have stock system and boot partition. Stock boot image will boot only unmodified system partition. However you can have bank and streaming apps with Magisk - use systemless modifications and magisk hide feature.

Super Stucked, Nothing Helps now.

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.

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:
