Bootloader glitch - Huawei P9 Lite Questions & Answers

Any ideas what causes bootloader (fastboot oem get-bootinfo) to always give "unlocked" status and then behaves like locked on some commands? Even when I relock bootloader, status after that is still "unlocked."
And then on some commands, like "fastboot continue" I get "command not allowed" error.
Any ideas what could cause that?
Huawei is unresponsive, but before that, OEM unlock and USB debugging were turned on.

Zenfone 3 ZE552KL RELOCK BOOTLOADER

Hi friends,zenfone 3 bootloder opened the lock.Now I want to close .Relock bootloader.
Ive tried asking this before for my Ze520kl, someone said it isn't possible to relock the bootloader
I would like to know if someone has an update about that...
When I tried to root my phone (ZE552KL Androïd 7.0) I installed an app to unlock the bootloader of my phone (ZE552KL_SIGNED_Android_M_UnlockTool_2016_0715). I used it and ever since, when I turn on my device, I get a warning screen saying "Your device software cannot be checked for corruption. Please lock the bootloader." It sends me to this link for information. The notification disappear after 10 seconds and androïd starts.
I was quite stupid to do that because I do not have to knowledge to properly root my device. So I give up, but I would like to get back my device without that security warning.
I have already flashed it from the recovery menu, with an sd card, wiping data and cache. But it didn't work.
Any advice?

I found this on the bootloader source:
Code:
fastboot oem unlock
fastboot oem unlock-go
fastboot oem lock
fastboot flashing unlock
fastboot flashing lock
fastboot flashing lock_critical
fastboot flashing unlock_critical
fastboot flashing get_unlock_ability
but they're all untested, trying them would make you take the risk of
killing your phone
OR
locking the bootloader
keep in mind that Asus also keeps track of system mounts as read write changes, so if you're trying to fool them, locking the bootloader won't be enough
Commands do not work.

XT1700 Fastboot oem unlock fails

I seem to have lost the ability to unlock the bootloader of my XT1700. I previously had unlocked the bootloader and installed TWRP and SuperSU, which took a while to figure out, but it worked. Today I tried to install a newer version of the stock firmware using SP flash tool (from here), which seemed to work fine, except now I find I am unable to reinstalled TWRP or SuperSU because I cannot unlock the boot loader.
When the phone boots, I still see the "device unlocked" message, and I have enabled oem unlocking and USB debugging in the developer options menu, however when I go into fastboot mode, if I run the "fastboot oem unlock" command, when the phone prompts me to press up or down, I get an "unlocking failed" error, and Fastboot reports "Unlock operation is not allowed"
Any ideas on how I can unlock this device again?
So it seems like those firmware images must have locked boot loaders. I ended up installing an xt1706 firmware instead (from here) and was able to unlock the boot loader successfully.
Anyone know where to get xt1700 stock firmwares with unlocked boot loader?

OEM unlock toggle is not working

Hi.
I´ve unlocked the bootloader on my P10 plus.
But now, the toggle to unlock OEM on the developer settings is greyed and I can´t perform any fastboot commands.
Any help?
Thanks
I believe the option becomes disabled when you've unlocked the bootloader, as you'd have to use the relock command instead of the toggle to relock it.
I assume you're familiar with accessing and using fastboot if you've unlocked your bootloader... so for the fastboot commands, does the device show up when plugged in and you run "fastboot devices"?

i have my huawei p10 plus doing the same thing of yours.....only erecovery mode and when i get to boot in fastboot mode is only fatboot mode & rescue and i had locked bootloader and frp lock.....but i was reading that huawei just block the page to unlock bootloader i just dont know why they did that /......
Maybe try re-unlocking and flashing stock rom, kernel, system, and boot. (Or you can try the method I used to update manually). Requires to be able to acces external sd card.
Hmu if you want to know how.

How does one re-unlock the bootloader?

is it okay for me to just unlock the bootloader again?
Do I need to reuse the motorola code again?
Bootloader shows "flashing_locked"
EDIT: Just tried commands fastboot oem unlock and my code
fastboot flashing unlock
fastboot oem get_unlock_data
None of them did anything... Device just hanged...
To whoever has the issue of device not responding, what solved for me was using another computer and only 2.0
port. Using port 3.0, the COM Transfer rate would seem to be too high.
Now all that is left is getting flashing unlocked....
In my case using command fastbot flashing unlock unlocked immediately after pasting it twice
