Bootloader Unlocking ends in error - Android Q&A, Help & Troubleshooting

Hi,
I am having a tenor G phone (10. or G) which is more popularised in India but still lacks in development.
I can't able to root the phone or can't able to unlock the bootloader though there is the option in developer mode to unlock OEM whenever I tried to put the command "Fastboot OEM unlock"I ended in this error! " [ERR] Unknown Command error !!! OKAY [ 0.007s] finished"
If you need the specifications of the phone I have attached the link here http://www.gsmarena.com.co/2017/10/10-or-g.html

Hi there,
well first you need to type in adb reboot fastboot
then fastboot oem get_unlock_data
after that the command will give you a string of numbers and then you have to copy and paste those numbers on to the mobile companys bootloader unlock service website.
However since it's an Indian smartphone I am sure that the company will not provide such services as they restricted this service to everyone.....
However you can try and use KINGO ROOT to root your smartphone.
I am not sure if it will work but you can try it

For that too
I am getting the same error
Kingo root can't able to root this phone..I tried several rooting apps but not working

[UNLOCK] official method to unlock the bootloader

It looks like Huawei has made available an official method to unlock the bootloader.
http://www.huaweidevice.com/worldwide/servicePolicy.do?method=preUnlock
But i haven't tried it yet. Maybe it could lead to something useful.
both way to obtain product ID doesn't work on cm10 rom, maybe I need to use stock rom.

The form doesn't work correctly. Poor Huawei, they need to get some help from WEB professionals ...
If I select "Tablet" then "Huawei Mediapad" form the two select boxes then it is impossible to fill the IMEI/MEID field.
However if you press the "SUBMIT" button the system says "The IMEI/MEID can contain numbers and letters only.".
The procedure to find the "Product ID" is wrong, or it is not for the MediaPad tablet and doesn't work.
The string they suggest to type in the phone *#*#1357946#*#* or in the calculator ()()1357946()()
doesn't bring up any "Product ID" on my tablet. Probably this number is for other devices.
I just unlocked my MediaPad device by typing:
Code:
fastboot oem unlock
So I believe this device was not really LOCKED.

Correct ...
However I tried "fastboot oem unlock" as soon as I bought back in December.
Now with the following "fastboot" command my device shows:
Code:
fastboot oem device-info
...
(bootloader) Device tampered: true
(bootloader) Device unlocked: true
OKAY [ 0.004s]
finished. total time: 0.004s
while we have tested that for some others users it is:
Code:
fastboot oem device-info
...
(bootloader) Device tampered: true
(bootloader) Device unlocked: false
OKAY [ 0.004s]
finished. total time: 0.004s
You can try with your and see what you get.
I had a problem,.
I install Mediapad_2.06.26_OsiMood - Light gets Lighter on my Pad.
Now, I can not test CyanogenMod, because it is not come in "fastboot"
How can I do, thank you
anyone has any alternative to unlock the fastbooot Huawei Mediapad 7 v302u
If you have locked bootloader just flash older fw version. This or something older http://download-c.huawei.com/tcpsdownload/downLoadCenter?category=&flay=software&downloadID=NDYyNDc=

Once again thank you for contacting Huawei device.
Best Regards.

Please someone HELP ME unlock the fastboot, because this is the only firmware <<<HUAWEI MediaPad Firmware(S7-302u, Android 4.0, C235B001, EN, Network Function)>>> that I find perfectly working the way I need it, except I cannot install SU and CWM to root it because of this fastboot lock thing... I REALLY NEED HELP! PLEASE!!!
I have the TMobile Springboard 303u version, still waiting on network unlock code from tmobile... wonder if that code is going to work to unlock the bootloader too?
of only superuser you can try this way. inject su binary & superuser.apk to the official rom with linux command. set permission. then reflash it to your mediapad. but this can't fix the unlocked bootloader problem. this just add a superuser to official rom.

i did the unthinkable! (I am so stupid) In the effort to get a working unlocked bootloader, I stubbornly flashed the wrong bootloader by using the attached application [NOTE to everyone - do NOT use this attachment for anything! you will brick your device! i am only attaching it in hopes that somebody will fully understand what i've done & troubleshoot and help/guide me in the process of unbricking my device]
So can somebody please help me unbrick my device? I am a noob and I have Windows 7 Ultimate. I don't even know how to use Linux. The sad part is that I got SU and root right before I did this stupidity. I got root and SU with the software from this website: http://www.unlockroot.com/unlockroot.html
so officially now I am really begging for HELP with step-by-step instructions on how to unbrick my device? (again - I flashed the wrong bootloader from the attached file).
can you enter to bootloader (fastboot) mode?

No. Dead. Device doesn't even look like it is turning on, which is expected when one flashes the wrong bootloader. this is brick-brick dead. it doesn't get any worse than this...
maybe the JTAG method can fix it. but JTAG method is only for professional who really2 know how to use the tools.

what is JTAG method? are their detailed instructions for the T-Mobile Springboard? If there are detailed instructions for this specific device, then I can definitely do it. I've been pretty good so far at following all the instructions here. I've flashed many ROMs here, etc. The only time I get in trouble is when I go off and do stupid things like flashing the wrong bootloader... I'll never do that again! So yeah - any step-by-step instructions for Windows 7 user?
you can find it on google. it use some toolkit to flashing the board directly from PC.

Help unlocking bootloader for Huawei Y6

I couldn't find anything specific for this phone. All the tools/videos were made for other Huawei phones, so I'm skeptic to try them out.
I'm looking for a tool for PC which will help me unlock the bootloader on my Huawei Y6. I already got the code from the official Huawei site.
Also, recommend drivers which I'll need.
if you already got unlock password for boot loader now what?

I need a script/exe whatever to input the code so I can unlock the bootloader from my PC from what I saw in the videos I watched.
Don't trust that.
Install minimal adb and fastboot from here http://forum.xda-developers.com/showthread.php?t=2317790
Go into that folder, press shift and right click, then click "Open command prompt here"
When it opens, write "fastboot oem unlock xxxxxxxx" where xxxxxx is the code you received.
It should say "waiting for device".
Shut down your phone, connect it to the PC and turn it on using VOL UP + POWER.
Fastboot should do it automatically and unlock your bootloader.

Thats nice, but you're requesting in the wrong site. Have you tried a google site request?
I just did this tonight on my Huawei Y6 ATU L11.
Follow this guide first: dc-unlocker.com/how-to-read-huawei-bootloader-unlock-code
Then do this:
dc-unlocker.com/free-huawei-bootloader-unlock-tutorial
It's not free but it's worth it imo as stock on this phone is quite bad.
Can anyone make a tutorial on how to unlock the bootloader on this huawei Y6 with/without unlock code. Though I best prefer w/o unlock but even with unlock code will do. Thakns.
Did anyone find a rooting method for y6 2019 pro??? I've hunted posts everywhere to no avail, also tried getting bootlocker unlock code directly from huwaei, however, apparently they stopped giving these out a couple of years ago, I'm using this y6 2019 pro just now but it's pretty whack and they won't even upgrade it to andy10. Fookers playing god with their bootloaders. Give us em? any luck with it guys n gals?
Can you send me the code?
Pls send me the code sir/maam i really do need it i dont have money to use dc unlocker or any other kinds of $ hugry programs
If your kind enough send it to my email ?

There is no code because huwaei do not provide unlock codes, therefore each device including the y6 2019 remains with a locked bootloader, sell it and buy a Samsung or pixel

i'm not pro but you may have bad drivers or device is not completely unlocked,
try to completely uninstall any adb/device driver on your pc and install those ones,
besides that, check if device is detected with this command
Code:
fastboot -l devices
then try again with
Code:
fastboot erase recovery
fastboot flash recovery recovery.img
goodluck.

How did you try to unlock your phones bootloader?
There is no need of unlocking code just command " fastboot oem unlock" and that's it now check your boot loader status with command on fastboot and it Will show you unlocked,
But there is no benefits to unlock this phone you will never find a Root solution for this phone,so it is recommended from me that stay with locked phone,& if you found any suitable custom ROM just flash it with PC without backup,other then that so far i didn't found any safe solution.

Hello sir, i got permission granted by xiaomi for unlocking bootloader, then i downloaded the unlock tool in my pc. As soon as i click on the flash tool application, i get the error windows cannot access the specified device path or file. I graanted total control in properties, tried changing location, turned off all anti virus , none worked. So, another guide suggested a method to enable hidden admin account. He asked me to go to safe mode and type net user administrator /active:yes in cmd. But, when i tried safeboot>minimal via ms config, i got the notification, bitlocker encryption is enabled on your os drive and that i will need to provide a recovery key. Online i found certain ways to unlock bitlocker encryption without key or password. But i felt , this is too extreme, considering that my laptop is a company issue for work purpose. Kindly help. Unlocking permission is granted but unable to run the tool on my laptop. Thankyou very much

This has nothing to do with Bitlocker.
The unlock tool needs admin rights to work. Did you start it as Admin?
Did you Install the drivers for your phone? I can be a problem if you run a 64 Bit version of Windows.
Did you try different USB cables?
Did you try different USB ports on your laptop?

Enable USB debugging in developer options.
Try older versions of the unlock tool.

Now that you know which drivers work for you, uninstall all the previous versions which you installed and reboot your PC. Then only install the one which works for you and reboot your computer again.
Then try using the latest MiUnlock tool.
I tried opening the latest unlock tool with the new drivers installed, same error continued. Tried few other online solutions, futile again. At last went to a nearby cyber, within an hour, phone unlocked, redwolf twrp recovery flashed, magisk system less root installed. Lol!
Thanks a lot though guys, appreciate your help

Unlocking Bootloader & Root On LG K40

Having trouble rooting my LG K40. I have the same problem as this person when trying to boot into fastmode: https:// youtu.be/yQ99lQv0rQk?t=26
You can find his post here explaining the process more in detail: https:// lgk20.com/root-lg-k40-lm-x420-bootloader-unlock-twrp/
MODEL #: LM-X420MM
Any help is appreciated,
Thanks in advance.
im having the same problem. i must have a proclivity towards phones with what seems impossible rooting methods. the first was the samsung j7 prime and now the lg k40 lmx420mm. ive gotten as for as adb reboot-bootloader, just restarts device, fastboot commands are either not recognized or i receive "waiting on device". Ive updated drivers, followed a diff. method found on reddit posted by jamesrascal (i cant post url here because of my newb status). Phone just stays stuck in firmware update. i feel as if ive exhausted all resources, any direction or help would be appreciated, im not educated on rooting ive been successful a few times on other phones and jailbroken some iphones, im mostly doing this to learn and teach myself so it isnt urgent but i need help to continue any further. thank you
Same problem for me. Because the device has good value for the money it would be nice someone can help us here.
Further this device seems to be full android treble conform I like to know how benefit from this circomstance.
I have LG K40 LM-X420EMW with dualsim.
Thanks for every hint!
@blanksus
IIRC an Android user can not unlock the bootloader without first OEM unlocking, because without this process the device will not accept the bootloader unlocking command.

OK, but it is not possible to get into fastboot mode to enable the OEM unlocking. I marked the slider in developer option butz still there is no chance to get in fastboot mode.
After command "adb reboot bootloader" the device always reboots in normal system mode.
@baerenbisch
Once you enabled the OEM unlock on your Android, the “unlock ability” flag is set to 1, which allows you to use the
Code:
fastboot flashing unlock
command what unlocks device's bootloader.
BTW: Once you have enabled OEM unlock, it stays on. Even if you do a factory reset, it stays unlocked until the setting is manually altered again by going into the Developer options section.

Hm,
may be it is "allowed" to unlock but in the "LG K40 (LM-X420EMW) real world" it is not possible.
You dont reach fastboot mode which could enable using the order you proposed.
Device reboots into standard mode instead of wanted fastboot mode after sending "adb reboot bootloader"
I think thats the problem.
Code:
[email protected]:/# adb devices
List of devices attached
LMX4205P4TU4S4HEOJ device
[email protected]:/# adb reboot bootloader
[email protected]:/# fastboot flashing unlock
< waiting for any device >

Temp root does sound nice, but what can you actually do with it. Can you change the OEM unlock key?

Device can be bootloader unlocked now. MtkClient on github. I have the Harmony 3 bl unlocked and twrp for it
Can confirm, I was just able to unlock the bootloader with mtkclient and root with Magisk from there.
