Is my phone bootloader locked? - Honor 7X Questions & Answers

In fastboot mode I see -
PHONE locked
FRP unlock
Command "fastboot oem device-info" returns "FAILED (remote: Command not allowed)" though "fastboot devices" lists the device.
HCU Phone Info returns below in fastboot mode -
FB LockState: LOCKED
USER LockState: LOCKED
locked
And in normal mode Phone Info returns -

I also purchased 4 credits from dc-unlocker but for some unknown reason they refunded the payment and so not able to read the bootloader code.
Thanks for any comments!

Yes the first line says "phone locked"
That is bootloader.

Thanks, was expecting it but wasn't sure which one indicated it. Considering I am still on 5.1 / 7.0 and Feb security patch, would dc-unlocker with a 4 credits be able to read the code? Or it wouldn't help (even if it can read) in unlocking since "oem" commands are not being allowed?

Well only certain oem commands not work while phone locked.
I can't say why it did not give you a code. Maybe you missed a step on process.

All I did was put the phone in fastboot mode and connected to the PC. Before that I did enable OEM unlock in developer options but not sure if it had any effect on fastboot.
"fastboot devices" listed the device but none of the oem commands like "device-info" or "get-imei1" work (remote: Command not allowed). The bootloader code didn't work probably because dc-unlocker refunded me the money ($4.80) for some unknown reason and no credits available. When the bootloader read didn't work from HCU, I didn't notice the credit issue and was wondering whether I needed 15 credits (needed for the newer phones). Do you think 4 credits would do for my phone?

Just an update - I was able to unlock the bootloader with 4 credits following Wh1t3Rose guide. Dc-unlocker refunded the credits first time and that caused bootloder read to fail. Now have to get AT&T bands added, if possible... will start a new thread.

Soft-bricked MediaPad M2 803L

Hi everyone,
It seems I was stupid enough to choose a wrong model (MediaPad M1) in TWRP Manager (downloaded from Google Play) while attempting to install TWRP recovery.
This resulted in an infinite bootloop where the "Huawei MediaPad" logo keeps appearing, the tablet restarts and again the same.
I do have access in Recovery and Bootloader mode, but all my attempts did not yield any results. Things I have tried so far:
- Download the Stock ROM from needrom.com (versions B009 and B019), extracted them and loaded the "dload" folder onto an SD card and executed recovery (by pressing both Vol UP/DOWN and starting the tablet). Even though the procedure seems to be perfoming normally, indicator reached successfully 100%, when the tablet restarts after the supposed successful recovery I am still left with the same bootloop.
My SD is a 64GB one, formatted with exFAT if this makes any difference.
- I have tried extracting UPDATE.APP using Huawei Update Extractor (http://forum.xda-developers.com/showthread.php?t=2433454) and tried to push via fastboot all necessary parts (i.e. BOOT.img, RECOVERY.img, SYSTEM.img, etc) but I get the "FAILED (remote: Command not allowed)" error message.
My bootloader was unlocked from the beginning (at least that's what showing when I enter bootleader/rescue mode with red letters - "PHONE UNLOCKED").
Any suggestions would be greatly appreciated! Thanks!
What commands are you using? It is peculiar that fastboot mode fails to flash. It may be that your bootloader is not properly unlocked even though it shows that it is.
If you have a bootloader unlock code for your device, I would suggest that you try explicitly unlocking the bootloader when in fastboot mode (it won't hurt to do this even if your bootloader is already unlocked):
Code:
fastboot oem unlock <YOUR_BOOTLOADER_UNLOCK_CODE>
Then you can verify that the bootloader is actually unlocked by issuing the following command:
Code:
fastboot oem get-bootinfo
If your bootloader is properly unlocked, then the previous command should return output similar to the following:
Code:
(bootloader) unlocked
OKAY [ 0.001s]
finished. total time: 0.002s
At this point, let's try to restore your original BOOT partition and RECOVERY partition.
Now, gather the following partition images from your OEM firmware package:
BOOT.img
RECOVERY.img
SYSTEM.img
USERDATA.img
Only BOOT.img and RECOVERY.img should be needed to solve your issue, but we'll have SYSTEM.img and USERDATA.img ready and available here just in case our efforts fail with just boot and recovery alone.
Now erase and flash boot and recovery as follows (replace /path/to/oem/ in the commands below with the full path to the files you extracted from your OEM firmware):
Code:
fastboot erase recovery
fastboot erase boot
fastboot flash recovery </path/to/oem/RECOVERY.img>
fastboot flash boot </path/to/oem/BOOT.IMG>
fastboot erase cache
fastboot reboot
Hopefully, at this point your bootloop issue is resolved and your ROM boots normally. If not, then read on.
Uh oh, time to flash SYSTEM.img and USERDATA.img too and see if that makes a difference. While we're at it, let's also reflash BOOT.img and RECOVERY.img. Use the following commands (replace /path/to/oem/ in the commands below with the full path to the files you extracted from your OEM firmware):
Code:
fastboot erase recovery
fastboot erase boot
fastboot erase system -w
fastboot flash recovery </path/to/oem/RECOVERY.img>
fastboot flash boot </path/to/oem/BOOT.IMG>
fastboot flash userdata </path/to/oem/USERDATA.IMG>
fastboot flash system </path/to/oem/SYSTEM.IMG>
fastboot erase cache
fastboot reboot
...and hopefully now you're back up and running.
Good luck!
In case you don't have a unlock code and *already* bricked it, you can get the imei from fastboot as well. Simply send the following command from fastboot:
fastboot oem get-psid
Using the imei you can then request an unlock code from huawei on their web site.
Thank you both for replying!
Unfortunately, I don’t have an unlock code. I have contacted Huawei through https://emui.huawei.com/en/plugin.php?id=unlock&mod=detail months ago asking them for an unlock code for the bootloader but I never got a reply. I have even tried again a couple of months ago but they didn’t answer back. It seems there is a limitation on the time entitled to ask for an unlock code – I believe 3 or 6 months if I remember correctly.
I have just tried contacting them again through an e-mail form, let’s hope this time they’ll reply.
Now please allow me to fill you up in some more test/trials I did today:
I issued the “fastboot oem get-bootinfo command” and the result is this:
(bootloader) unlocked
OKAY [ -0.000s]
finished. total time: -0.000s
(Not even a milisecond in replying. This looks a bit suspicious, right?)
But when I try to continue as per your instructions (i.e. issue the command “fastboot erase recovery”) this is what I get:
erasing 'recovery'...
FAILED (remote: Command not allowed)
finished. total time: -0.000s
So I cannot go on using your suggestions
I have also tried to use DC-Unlocker to unlock the bootloader (perhaps wasted money since the bootloader is already unlocked but I just wanted to try). When I bought the credits and opened DC Unlocker Client, the option for Unlock was grayed out, but the option for Factory Reset Protection was selectable. Based on this, I am now suspecting that the tablet has got FRP protection enabled, since I did have a PIN set-up before choosing the wrong model in TWRP manager and brick it. So I tried DC Unlocker’s Factory Reset Protection (paid 15 wasted euros!) but again no luck. This is the log from that attempt:

Since I already paid the €15 at DC Unlocker I decided to give a go using their other piece of software, DC Phoenix. This one allowed me to flash pieces of the UPDATE.app package while in fastboot mode, without complaining about locks. It seemed to be flasing normally (I tried flashing all contents of the latest UPDATE.app package) and then (as per DC’s instructions) I tried re-flashing everything using the second option (Upgrade Mode) while in Repair mode (i.e. Vol +/- pressed while powering the tablet).
No success either – Tried various combination of DC Phoenix – even only the files you suggested (BOOT & RECOVERY, BOOT & RECOVERY & USERDATA & SYSTEM).
Is there a way to find out if FRP has been activated through fastboot? Tried Googling it but no usable results came up.
Any other suggestions would really, really be appreciated!

I did contact Huawei for an unlock code, myself - I sent emails to [email protected] and [email protected] and received a reply back from them the next day. Here is what they said:
Dear User,

I didn't want to faff around with all that logging in nonsense for two weeks, and also the Huawei bootloader code site seemed to be offline (kept getting "Page not found" errors with the error page in Chinese characters and what was ostensibly an HTTP 600 error, which was why I contacted Huawei support over email), so I just ponied up about $4.25 for 4 dc-unlocker credits (4 euros) and got my bootloader unlock code from the dc-unlocker software. Neat, clean, easy and non-messy.

Yes, that does seem very odd. I would expect it to take at least some time in userspace (the "total time" field).

I find it very peculiar that your bootloader is unlocked but FRP is activated. I think that dc-unlocker does not give you the option to unlock the bootloader because FRP protection is still active - according to all guides, FRP must first be deactivated if you want to unlock the bootloader.
What does your phone say in the bootloader screen for the FRP? You'll find it directly under the "Phone Unlocked" text. It should say either "FRP Locked" in green or "FRP Unlock" in red.

There isn't, directly, but you can try to issue the fastboot command
Code:
fastboot oem frp-erase
although at this point I am not very hopeful that it will work.
FRP is nothing but the developer option to allow an OEM unlock of the phone - it is the option mentioned in this image in the Huawei "Unlock bootloader" guide thread.
Like I said, I find it very peculiar that FRP is enabled but the bootloader is "unlocked". Did you at any point reset the developer options or reflash the stock ROM before you soft-bricked the device? Did you pick up this phone second-hand/used or something?
I think that the root (excuse me, I couldn't resist) of all your problems is that FRP is still enabled, and this is what is causing your flash attempts to fail.
Here is the dc-unlocker guide to repair a bricked Huawei phone even if the bootloader and FRP are locked. If you follow this guide very carefully, maybe it can save you. Since you already seem to have tried "Method 1" of the guide, maybe you can try "Method 2".
Another suggestion I have is that you can contact the dc-unlocker guys for online chat support (when you see that the chat is online). They are very helpful, and since you've thrown so much money at them (be sure to mention that, just in case they don't know), they should be able to do something to help you out. Good luck, and I hope that you can get your phone back online...
I've been faced with all the same issues as the OP for the last 24 hours and thought all was lost. I had been through all the same stuff - every fastboot command and every key combination possible. I'd tried different tools and apps to get some life out of the device but no luck. I had even downloaded the ROM from beast.in.black's thread and extracted it to the SD card but it didn't do anything for me.
Worse still, the tablet was now out of juice. And as soon as I plugged it into the mains, the screen lit up and the all too familiar fastboot screen would stay on, meaning the tablet was barely charging long enough for me to try anything new with adb / fastboot or whatever.
So in trying to get the screen off and charge the tablet, while it was plugged in I held vol up / vol down / power together for 10 seconds. I was hoping this would leave the screen off (I had managed this earlier while plugged into USB) but instead it booted again. So I walked away for a minute, then came back expected to see the fastboot screen but no, it was in the middle of an EMUI software install. Huzzah! I left it to do its thing but at the end, it came up and said install failed and my only option was to press power to reboot. Sigh. So I pressed power and then got another surprise. The Huawei boot logo. The tablet was booting. A few seconds later I'm at the "Choose your regional settings & language" screen in the setup wizard. After trying everything under the sun, it turns out all I needed was the ROM on the SD card and to give the tablet the three-finger-salute while plugged into mains.
Happy days!
I found the Official M2-803L ROM!
For anyone who needs it, I've found an official download (direct from the Huawei China support site) for the M2-803L.
I've posted the ROM details here for anyone who needs this ROM.
Status update for anyone that might be interested: I was able to restore the tablet with the help of DC-Unlocker. I highly recommend them for any unlocking/restoring needs.
More specifically, I contected them via email and they were kind enough to give me credits (since I already paid them) in order to try again with Method 2 as per https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
Step 2 of this method did not work for me (i.e. flashing in upgrade mode) but I was able to replace this step simply by re-flashing with DC Phoenix in fastboot mode.
After this, my IMEI was zeroed-out (that was a problem since this tablet is 4G-enabled thus I couldn't register on my provider's network) but I was also to fix that by using HCU-Client (had to purchase 8 more credits from DC-Unlocker).
All are working fine now.
Special thanks to @beast.in.black for pointing me towards the right direction!

Hello,
I'm planning to buy this device, specifically the XT1684 or XT1685 variant. Are these specfic variants supported and are there any culprits I should be aware of? For example, is there a possibility of me being locked out like with LG's G/V series devices? Or is the bootloader unlock procedure completely smooth?
thanks for the guide. I have just unlocked it.
Any guide to root it?

Can't say for sure since I don't own the device, but I guess flashing the SuperSU zip in TWRP will do (when the TWRP for this device releases, that is).

The instructions worked for me, allowing to unlock the bootloader. Device was a reconditioned moto g5 plus (XT1685) bought from amazon (not an "amazon exclusive", the international version).

How to re-lock bootloader

I recently purchased a used Pixel C. The previous owner stated that the bootloader is unlocked but he never flashed anything. It is running stock. I want to re-lock to the bootloader to do away with the annoying message upon boot up. What is the appropriate fastboot command? Some posts make mention of new fastboot commands. Thanks
reboot on fastboot mode
type: fastboot flashing lock
wait for format userdata
done
Solved
Thanks. That worked perfectly.
Hmmm... My bootloader is unlocked and the developer option is grayed out to lock it.
If I follow these commands to lock via fastboot ("fastboot flashing lock") I get the following error:
FAILED (remote: Enable OEM unlock is not set)

No longer a problem for me since I think I'll probably run rooted with the final rev of lineageos +microg and Magisk. So I need to stay unlocked anyhow.

I just flashed LOS17.1 yesterday and HOLY crap it's great. Good call.

remote: oem unlock is not allowed

Hi,
I am using my Nextbit Robin Oem Unlock from last 1 year but today i decided to go back to stock with locked Oem.
I flashed the stock rom and locked the Oem at the same time but when i restarted the phone it got stuck at the boot.
So I went ahead with the 'fastboot oem unlock' command, and here's the problem. All flashing command returns FAILED <remote: device is locked...>.
fastboot oem device-info reads: Device tampered: false, Device unlocked: false. So bootloader is locked. At this point I assume that the bootloader is unlocked, but revert back to locked after reboot (the phone automatically rebooted after executing oem unlock command, so can't get around that).
Tried numerous other methods, using different adb files, no dice. Can't even flash TWRP. Tried adb sideload, same. Tried executing fastboot oem unlock with various different parameter, still locked after reboot. I cannot flash anything into locked bootloader.
Google researched it for few hours, same problem happened to other phones from other manufacturers that came returned from warranty replacement with modified motherboard; OR tampered/broken eMMC/NAND flash. But no such case for Nextbit Robin (yet?).
Pretty hopeless right now since I just found out that Nextbit Robin support ended on Aug 1st.
Guess I'm stuck with locked bootloader and no cell signal phone. Unless someone can help. One can always hope.
Anyway, thanks for reading.

If you bootloader is unlocked I think you can give a try to the Nextbit's Unbrick Tool
As you want to go back to stock , I think this is a good idea.
Now if your bootloader isn't unlocked there is unfortunately nothing I can do for you , unless you unlock it .
Edit #1: If your bootloader is locked , go to bootloader mode by pressing volume down + power button for about 20 seconds and try to see the bootloader state with fastboot commands. If it is unlocked , follow the process in the @nextbitKhang's thread .
Yes that's the main issue. Oem is Locked.
Is there any Oem unlock code i can use to unlock from ADB?
I don't think so ,I'm not sure, but I hope you'll find one.
On your Robin go to settings > system > about phone > tap build number until it shows developer options.
Go into developer options which is in settings > system > developer options.
Make sure OEM unlocking is enabled. (for good measure disable then re-enable)
Also make sure usb debugging is enabled. Have the Robin plugged into a computer so you can enable to pop-up on Robin asking for access for the computer.
Once they are both enabled shut down your phone. Turn it back on while pressing vol down+power and plugged into your computer.
In adb run command fastboot oem unlock
please i'm experiencing the same issue not on nextbit but on GIonee.
i have re-activate both OEM unlocking and USB debugging several times but it all void
same error: Remote: OEM unlock is not allowed
please kindly help

Alt Data Input method for Moto Unload Site - (Updated instructions 17 June 2023)
Note:
Moto Site is finicky, and instead of it saying I'm sorry there's an error, it just says​"Your device does not qualify for bootloader unlocking."​So if you get this notice but you have a qualifying Cid (see post #3)​try again later.​
Carrier-exclusive models (ex. Verizon, AT&T, Tracfone) are almost never unlockable.​Bootloader unlock codes are not available for Amazon Branded devices​

Be careful not to remove part of the unlock key, when removing the junk, spaces and extra lines.

Locking Motorola Bootloader
Relocking Motorola Bootloaders can be difficult.
Don't relock the bootloader if it was unlocked by any other method than Offical.
ReFlash Stock Firmware, Factory Reset, Reboot. and make sure everything is working correctly before relocking.
Current locking instructions - 27 April 2021
You can't relock the bootloader without the stock firmware!! - Jun 1, 2020
If the device was rooted, reflash stock firmware.
Your device likely uses fastbootd
[Guide] Flashing Motorola Firmware
After flashing Firmware, power up the phone to make sure it will boot.
If it starts up ok
return to bootloader and run
Code:
fastboot oem lock
Follow the instructions in your terminal's output.
You should see something like "signed system image required" which means you have to
Flash all system.img_sparsechunk.X parts a second time.
When finished run the lock command again and follow the instructions in your output line.
Continue until your bootloader is locked.
Other methods that have worked in the past
Run
Code:
fastboot devices
fastboot oem lock
fastboot oem lock
fastboot reboot bootloader
Check if bootloader says
Code:
flashing_locked
If the bootloader doesn't lock
You may need to try something like.
Code:
fastboot oem lock begin
fastboot oem lock begin
fastboot oem lock
fastboot oem lock
fastboot oem lock
fastboot flash boot boot.img
fastboot oem lock
or
Code:
fastboot oem lock
fastboot oem lock
fastboot flash oem oem.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash boot boot.img
fastboot oem lock
I saw the same thing on my end at first. Found this to work repeatedly....
fastboot oem lock (enter this a few times until i says something to the effect of...."you still need to flash a signed boot.img")
fastboot flash boot boot.img (this will now flash fine without saying the image is not signed)
fastboot oem lock (if you prefer to re-lock. You'll need the unlock key again if you plan to unlock).

Head on over to https://support.lenovo.com/us/en/downloads/ds101291 and download the tool, after installed put your phone in bootloader/fastboot mode and go through the rescue steps up until the firmware is downloaded, do not click rescue after the firmware is fully downloaded just head on over to C:\ProgramData\LMSA\Download\RomFiles and open the downloaded firmware and take the boot image from there and copy it to your fastboot tools folder and flash that boot.img check that the firmware matches the version installed on your phone before flashing the boot.img.

Re-lock bootloader without OEM unlocking
It's been 7 days since I came back to stock already and OEM unlocking is still greyed out. Is there any way to force it true so I can relock bootloader? That happened when I first tried to unlock bootloader, but I could allow it in like 4 days If...
forum.xda-developers.com
flash either stock or a stock-based rom along with Magisk and enable OEM unlock in the dev options and the you should be able to re-lock.
Click to expand...
Click to collapse
Magisk Hide must be enabled. Only this option hides the unlocked bootloader which results in an active toggle for the OEM Unlock option.

You have to remove the hashtags "#" from the code you get from the phone.
Remove the quotes "Part1" from the link below.
Code:
https://support.motorola.com/us/en/api/mse/bootLoaderVerifyPhone?serialNo="Part1"&secSerialNo=&processorUid="part4"&bootloaderHash="Part3"&infoOnly=N
There is a chance this could change with newer devices.
The 1st part should be 16 characters long.
The 4th part should be 32 characters long.
The 3rd part should be 40 characters long.
Click to expand...
Click to collapse
So, a good unlock code will look like this. Mine is 19 characters long.
Code:
{"status_code":"0000","status_description":"Successful!","Boot_loader_unlock_code":"7*****************B"}
If it cannot be unlocked. It maybe something like.
Code:
{"status_code":"0020","status_description":"Either there are errors in input data or this device does not have bootloader lock code available yet.","Boot_loader_unlock_code":null}
if you see
Code:
{"status_code":"0003","status_description":"Processor UID cannot be empty!","Boot_loader_unlock_code":null}
the link is not correct, try creating the link again.

Trouble unlocking bootloader? try this! by jbtumbleson
Just copied from link below
Setting lock/unlock properties​The ro.oem_unlock_supported property should be set at build time based on whether the device supports flashing unlock.
If the device suppports flashing unlock, set ro.oem_unlock_supported to 1.
If the device doesn't support flashing unlock, set ro.oem_unlock_supported to 0.
If the device supports flashing unlock, then the bootloader should indicate the lock status by setting the kernel command line variable androidboot.flash.locked to 1 if locked or 0 if unlocked.
For devices that support dm-verity, use ro.boot.verifiedbootstate to set the value of ro.boot.flash.locked to 0; this unlocks the bootloader if the verified boot state is orange.

Unlocking the bootloader will disable FRP

Is the bootloader Unlocked?
You can check if the bootloader is unlocked with
Code:
fastboot getvar securestate
If you see this the Bootloader is still Locked
Code:
securestate: oem_locked
If you see this the bootloader is UnLocked
Code:
securestate: flashing_unlocked
Why is OEM unlocking greyed out/ unavailable?
It's not unusual for OEM unlocking on Moto devices, to be greyed out.
You need to connect to wifi/LTE and it should be available in 3 or so days after that.

Yes, Locking Moto Bootloaders is a mess.
Locking is actually more likely to cause a bricked device than unlocking.
The only advice I can give is the following
Follow the instructions in your terminal's output.
You should see something like "signed system image required" which means you have to
Flash all system.img_sparsechunk.X parts a second time.
When finished run the lock command again and follow the instructions in your output line.

Thank you. Since all I really want to do is restore deleted text pics and data, Is there any other way you might recommend that doesn't require an unlocked bootloader?
I have also read an article suggested to install TWRP and that the bootloader doesnt have to be unlocked in order to do it. Therefore , enabling root like capabilities. Any thoughts on this?
And another article saying that the Tracfones will unlock after 12 months and 1 day of service?
