Your english is just fine, do not apologize for it. And use spaces after "." mark.
So to the point; you cannot. Bootloader can ONLY be unlocked if you can access your phone, so basically you have to turn it on and do stuff within the OS. So no. You cannot.
BUT you could try the official dload -firmware update method. Just google it and you are going to find a lot of matches. For me the dload -method did not work (after my phone got stuck in bootloop after the official OTA upgrade to Lollipop. It should go under the warranty so I'm fine. Gonna send it tomorrow.) But since what you've done will void warranty, you can do nothing. But don't worry, since you can send it to a local Huawei shop etc. and they can fix it. But you gotta pay for it. Something about $30 if it's only a firmware flash and about $150 if they have to change the main chipset.

If you can get it into fastboot mode you bootloader unlock it using ADB with a PC.
You need your IEMI number, serial number and product number to get the unlock code from the Huawei web site. Emailing them is pointless. The phone doesn't need to boot to it's OS at all. If you can unlock the bootloader, flash a genuine ROM from dload folder of SD card or flash TWRP recovery via ADB then install a ROM from SD card.

How am I supposed to get the product number? I thought it required the phone to function properly and to turn on. Plus http://emui.huawei.com/en/plugin.php?id=unlock&mod=detail is always down. After logging in it gives this "We're sorry but the server is busy..." error.

How to Relock bootloader

Hello all.
I attempted to flash a ROM a while back and failed miserably. All I managed to do in the end was unlock the bootloader. I would like to change this, and set things back to they way they were; locked bootloader.
Is there anyway to achieve this? I would like to be able to use apps like Uber that won't work with an unlocked bootloader.
Any and all help is greatly appreciated.

Hello I think this could help you
https://youtu.be/8OywEYZ2cbw
This is a video about how to rebrand your mate 9
Now it in the steps it says that after you use the options 2 to rebrand it relock your bootloader, I don't know what mate you have but since you probably installed a custom recovery it is why you can't relock with the command, so my suggestion is this download the WHOTA update and also install the the software finder via Google Play. With it look for your specific model and copy the links to download the files for your specific model in your PC, Also do a Backup of your Oeminfo via the TWRP since it will be the only file you won't find, probably (if it happens to be the MHA-L09 C605 send it to me I need it for my phone I made the mistake of not backing up my Oeminfo).
If you download the files and follow the instructions of the video you will be able to relock your bootloader. But watch it 3 times and also download all the files and make sure to back up everything in your PC if something goes wrong.

Thanks guys. I've found a fairly simple solution.
This is the solution that worked for me.
1. Type "fastboot oem relock (your phone's unlock code)" and select unlock or yes with volume buttons & power.
Hopefully this method will help others.

If you are sure about whether your partitions are set up for Android N or Android O and use the correct update.app file, FHUnbrickFlashTool will get it booting again for you. The lack of guarantee is because a percentage of people use the wrong update.app file, and destroy their phones in the process.

If you rebrand you need to flash firmware twice in HWOTA. First select "rebrand", after this you need to unlock bootloader again and run HWOTA, but select "same brand update".

You can use this tool: https://forum.xda-developers.com/p9/help/how-to-product-id-bricked-p9-t3561156
Direct link to tool: http://rootjunkysdl.com/files/?dir=Huawei P8 Lite (Download Huawei Product ID Generator.exe)
Follow instructions in first link. I have tested and it generates a valid Product ID, I even tested on huaweis site to get my unlock code (which matches the one I get using my own Product ID)
Just make sure you follow instructions.
Edit: To get serial no, just boot to fastboot and use cmd to enter command fastboot devices
the number to the left is your serial no.
In my case:
C:\Windows\System32>fastboot devices
AHK0217111000149 fastboot
AHK0217111000149 is my serial no.
Edit 2: Oh, you had serial no already. I'll leave it in case anyone else finds this.

Are you selecting Huawei Y300-0100 in the generator? It doesn't work with any other model. And then you have to select "before emui 5" on the emui website and select phone as Y300-0100.
And try both IMEI.
If youre willing you could PM me your IMEI later and I'll try. I'm at work but home in about 6-7 hours.

If CMD states ur bootloader is already unlocked, u could be flashing to the wrong partition.. Are u using android N or O. Android O uses the updated twrp version so u will need to flash that version to the correct partition then u be able to boot to twrp and load ur OS

I've experienced it saying it's unlocked, but it's actually not. Have to fastboot oem relock xxxxxx
Then fastboot oem unlock xxxxxx
Xxxxx= password.
But one would need their unlock code for this.

you have to get into TWRP , make a back up of the OEM infos (on ur sdcard) then download the correct c432 oem infos , copy then to replace previous saved oem from twrp you ve done earlier ... then run htwoa and - if not enough - do the way as suggested by Ante0 (twice hwota / change brand for 432 then same brand)

System has been destroy + Usb debugging OFF + Bootloader Locked

Hi community
First Thanks to the people who take time to help, and admin that create that forum. Im always glad to see that s there is still people caring about helping each other
I come to you cause I spent the last 2 days trying to fix my brand new phone.
Brand : Xiaomi
Model : Mi ultra
My Computer : MacBook Air
Problem : "The system has been destroy"
Other problem :
- USB debugging OFF (not able to access to the phone in any way)
- Bootloader Locked
How its happen :
After installing an EU Rom, I re locked the boot loader using Adb... And it crashed.
I tried almost everything you find on internet using a Mac and till now nothing worked.
I tried to unlock the boot loader using ADB, which one the only thing who seems to be working and I got an error message saying that the Miunlocktools was too old ... ?
The token was available, as I already unlock it.
Does anyone know how I can switch ON the debugging mode without accessing my phone, or Unlock the boot loader using my Mac.
It seems there is solution possible but using windows computer, and tbh I will not buy a computer just for that.. for the moment
Thanks in advance to everyone
PS : I will offer 50USD straight in BTC to the one who will provide me the solution that will help me to fix it

Locking / unlocking a phone's bootloader is done by means of Fastboot, not ADB.
ADB & Fastboot are 2 completely different things. Don't confuse them.
AFAIK you can't enable ADB ( USB debugging ) from outside, this can only get enabled from inside ( Android Settings -> Developer options ) unless one creates/provides a flashable, properly signed ZIP that contains the code ( read: update-binary script ) to rewrite device's build.prop file entries accordingly.
BTW: A locked bootloader always tries to run device's Stock ROM.

Thanks for your quick answer. In other word, is it possible ? I am looking for what you say.
If I rewrite it, will I be able to switch it ON then ?
Im not at all a professional , that's my first step in this "world". It seems difficult, I will need to read a lot I think
What do you think about the EDL cable also, do you think it can work ?

IDK.
Never have bricked a phone. And I never owned a Xiaomi device.

locking a bootloader (at least in xiaomi phones )results in the phone being reformatted and the stock rom is installed
also try installing the newest version of miunlock https://en.miui.com/unlock/download_en.html
you might have to wait 7 days or less or more or might not have to
