Bootloader locked or unlocked checking

There is any method to know my phone bootloader is unlocked or not?
I suspecting that my phone is Chinese version and technical from mobile store flash Global firmware on it.
I saw him running my phone on fastboot mode to flash Global firmware.
P/s: I'm using SD variant

While in fastboot mode issue this command
Code:
fastboot oem device-info
It will inform you of the lock status.

According from some 'research' I do before, this is locked.
I applied for unlocking bootloader, will have to wait 10 days or something for approve.

Correct your bootloader is locked.
Getting permission can take up to 2 weeks, but got mine in 2 days.

Don't know where I read this tip.
Have you got the correct drivers for your device installed.
Try installing English version of MiPCSuite, which will install the drivers for the device as well.
Edit: Or install Miflash which has the RN3 drivers also.

A2017G fastboot oem lock

Hi
I am trying to relock the BL for warranty.
I did a EDL-FULL-Nougat, then found out that Nougat does not boot into bootloader.
So I downloaded A2017G_NrollbackM from ZTE, which worked nicely. I'm in bootloader now and see
Code:
C:\>fastboot getvar unlocked
unlocked:
finished. total time: 0.008s
which was expected.
... just I don't understand, why I can't lock or get oem device-info
Code:
C:\>fastboot oem device-info

The 15 seconds ADB installer should install the newest fastboot available. But be sure to get rid of the old installation

How to be sure?
Uninstall all related driver programs, check usbdeview on connected device and uninstall accordingly.
Connect and axon does not get fully installed, yellow ? In device manager. Install with local google usb_driver does not work.
Only with ZTE driver I got adb device. Then adb devices and fastboot devices works. But still can not lock.
I found my old aboot_lock.img from unlocking backup... But it's getting more scary step by step.
Not sure what I did wrong along the way.
EDL FULL then original MMrollback. Shouldn't this be all stock ZTE everywhere? Why fastboot does not like me...

This hasn't got anything to do with the drivers. I mean, delete the fastboot.exe and adb.exe that you have, then download the "15 seconds ADB installer" and install it, and try again

OK, a bit more digging.
I have 15sec-adb installed systemwide in C:\adb>
Code:
C:\adb>dir /B
aboot.img
aboot_lock.img
adb.exe
AdbWinApi.dll
AdbWinUsbApi.dll
fastboot.exe
strings.exe
as you can see, I put my aboot dumps there as well, and a strings-linux-like tool - after
reading this thread.
so, I got the ZTE driver to have my Axon7 visible to adb/fastboot (otherwise no device) ... and I have the latest 15sec adb here.
Code:
C:\adb>fastboot devices
823b48f5 fastboot
... but that's the only thing that works. not even easy things like this do
Code:
C:\adb>fastboot continue
resuming boot...
FAILED (remote: unknown command)
finished. total time: 0.015s
quoting the other thread
What’s missing in this list are fastboot oem commands. These commands are specific to Android device manufacturers, and there is no comprehensive list or documentation anywhere for what fastboot oem commands are available.
Click to expand...
Click to collapse
so I'm not sure if my fastboot version is the problem. I rather think that the Nougat->MM stock thingy, overwrite my Axon7 aboot.img with only a small set of fastboot commands available.
in my backup I see
Code:
C:\adb>strings aboot* | findstr /i oem
C:\adb\aboot.img: 04 0004 OEM_ID1
C:\adb\aboot.img: oem unlock is not allowed
C:\adb\aboot.img: oem unlock
C:\adb\aboot.img: oem unlock-go
C:\adb\aboot.img: oem lock
C:\adb\aboot.img: oem device-info
C:\adb\aboot.img: is_oem_unlock_allowed
C:\adb\aboot_lock.img: 04 0004 OEM_ID1
C:\adb\aboot_lock.img: oem unlock is not allowed
C:\adb\aboot_lock.img: oem unlock
C:\adb\aboot_lock.img: oem unlock-go
C:\adb\aboot_lock.img: oem lock
C:\adb\aboot_lock.img: oem device-info
C:\adb\aboot_lock.img: is_oem_unlock_allowed
so in old and new aboot I had oem-commands available, back then...
I'm not an expert, but do you guys really know that my problem is related to the PC-config I have, and not to the device-config?
I can not check aboot on device, as I'm not root.

update...
I did not succeed with fastboot commands, see above.
But, I flashed the A2017G B10_FULL_EDL package, and have no more 'not-verified-boot-screen-warning' ...
After miflash android greeted me with 'enter-android-password' ... I wiped cache/data again, now all good and -it seems- BL locked.
so, if you have access to EDL mode, try different EDL packages, you may end up like I did, full stock locked (at least it seems so)... good luck

Pretty sure miflash cannot lock your bl.

Technically I would not know why it should not be possible.
If it flashes block wise, it can update anything... for me the purpose of EDL.

I think it is still unlocked. I read something weird about the message not appearing after having a full stock system
But if you're gonna sell it/claim warranty, who cares?

Did you lock the bootloader after all?
I guess they wouldn't even notice if the 5 sec screen didn't show up lol

BL still unlocked.
I sent it with MM-B10-FULL-EDL, where 5sec screen was not displayed.
And got it back with MM-B06 ... with 5sec screen
so I guess what happened:
- ZTE turns on, does not see 5sec, repairs display, does usual EDR 'update' which is actually a downgrade to MM-B06, then sees 5sec-warn and thinks of what to do now, but as screen is repaired, what else than return
OR
- ZTE repairs screen (VIP) although bootloader unlocked
either way, all good.
what I learned is
- fastboot parameters need to be in aboot.img
- I can't do getvar or oem-lock until I flash another aboot.
Anyone with A2017G and unlocked BL who needs to send back:
EDL to A2017G_B10_FULL_EDL.zip
and hope you also have hidden 5sec screen (BL still unlocked)

PRA-LX1 stuck in bootloop, can't be turned off - locked, access to fastboot only!

Hello xda,
my cousin owns the P8Lite (PRA-LX1) and gave it to me to attempt unbricking it.
The device is stuck in a permanent bootloop, showing the Huawei logo. When pressing the power button for ~10s, it simply turns itself on again (even when not connected to a PC or the wall socket), which to me is very strange behaviour but I do not own a Huawei device.
I can get to fastboot (https://ibb.co/ixPtAn).
ADB does not recognize the device.
Fastboot does not let me boot a temporary recovery (be it the stock one or twrp), neither does it allow me to flash any file.
I have tried downloading the update.app file onto the root directory of the sd card and force the phone into the update mode (power, vol+, vol- at the same time) but to no avail.
Since it is not my own device and I cannot boot into Android at all, I have no way of getting to the IMEI of the device, which I would need to unlock the bootloader.
Is this device permanently bricked and a lost cause or is there still hope?

Hi,
IMEI should be engraved on the lower SIM tray if it's the original one.

Hi, sorry for the delay.
Try this, if not already tried: fastboot oem emmc_diag
It should check the status of emmc and tell you if it's ok.
Does this command: fastboot oem lock-state info work on your phone?
And putting the code Huawei sent you in this one fastboot oem frp-unlock?

No recovery, bootloader relocked

Hello, i have a serious problem with my U Ultra.... Last night I unlocked the bootloader, I installed TWRP(lastest version from official site), before all this I made backup (with TWRP) of every partition and then I make back-up of system, data, boot I think, I have everything on my laptop.
But I wanted to back on stock (Don't ask me why...) and i restored a back-up, a full back-up of every partitions. Everything great, but google play didn't had Device Certification: Uncertified like in this pic and I tried to do this method and it didn't worked and I don't know why I thought that if I will relock the bootloader, everything will be okay :| and now I don't have TWRP anymore and of course neither stock recovery, but the stock rom boots but the password I have made it, is not working.
Tried to unlock bootloader but this error shows up
Code:

I have the same issue after relocking my phone. Before I decided to lock my phone to downgrade to nougat, I did flash twrp and a rooted stocked oreo rom.

I'm still using the phone and I can't wait to get rid of it.
