Huawei CRO-L03 Bootloader Unlock Error - Android Q&A, Help & Troubleshooting

Greetings,
I have a Huawei Y5 Lite 2017 and I am trying to unlock the bootloader with my Windows 10 Computer.
I tried it with the CMD unlock various times but the same error appears each time. In the following is the code with the error:
E:\Huawei\Huawei unlock bootloader\unlock bootloader>adb reboot bootloader
E:\Huawei\Huawei unlock bootloader\unlock bootloader>fastboot oem unlock 753774CDDFFEDF2B
...
(bootloader) Start unlock flow
FAILED (remote:
Unlock failed - Err:0x7001
)
finished. total time: 14.156s
How can I fix this, I am running the CMD as Administrator and reset my device once but nothing helped, how can I unlock the Bootloader.
Thanks for your help.

Having trouble with unlocking bootloader

I got error when unlocking bootloader with flashtool (0.9.20.0)
FAILED (remote: Command not allowed)
I also tried with fastboot on commant prompt and got the same error.
And created a folder with my device's serial and put ulcode in it (folder is at flashtool/custom/mydevices) and got the error bootloader cannot be unlocked offically.
Rooting status in my device's service mode says unlock bootloader allowed:yes
My device is E6803
Is there anyone to help?
Any help?
Do you have OEM unlocking on in developer options?
Yeah man, I have. And that was the problem. Thanks for your help

Sony Xperia XZ: unlock bootloader FAILED (remote: Not necessary)

Hi Guys
I'm trying to root my device "Sony Xperia XZ (F8332)", and I have followed the steps in the develpoer.sonymobile.com, in the last step I faced this error:
..
..
C:..\sdk\platform-tools> fastboot devices
CB512CF1A4 fastboot
C:..\sdk\platform-tools> fastboot -i 0x0fce oem unlock 0x**********************
...
FAILED (remote: Not necessary)
finished. total time: 0.023s
Then turned on the device and then it did a reset factory, and I found the status for the OEM unlocking in the developer option says that the bootloader is already unlocked.
What does this error mean?
What I have to do to complete the root ?

Huawei Y6 MRD-LX1 bootloader unlocking and Rooting for file recovery : Err:0x7

Hi,
I am trying to recover recently deleted files (large number of pictures) and for that to unlock bootloader of a MRD-LX1 Huawei Y6
My only goal is to do a pull of mmcblk0 and then analyse it on PC. I also tried with dd , but all those don't work without rooting/unlocking
With "fastboot oem unlock XXXXXXXXXXXXX" I have been able to access a system menu on the phone asking to confirm the booloader unlocking, but when I select Yes with Volume UP, the process starts and I then get an error
(For information, an unlock code that "works" is the device number that you get with "fastboot devices" command.)
Code:
...
(bootloader) Start unlock flow
FAILED (remote:
Unlock failed - Err:0x7
)
finished. total time: 18.311s
I googled this Err:0x7 but it seems to be internal code error for Huawei company and I found nothing relevant
Does somebody knows either :
- how to solve this Err:0x7 ?
- how I could unlock the bootloader with an alternate method (Huawei Y6 MRD-LX1)?
- or just make a dump of internal phone partitions to perform my recovery.
Thanks a lot..
i have the same error (trying to root) and i can't unlock the bootloader pls help us
