You can't lock the bootloader with a custom rom.
Try https://spflashtool.com/

Hi, I tried it but nothing happened. I think that I have Snapdragon chipset and spflashtool is working only on MTK.

Ok but then why use an unlock tool for Mediatek?
Can you enter in fastboot mode?

Hello, I unlocked my kate version the official way. First I unlocked it using unofficial method, but I got the permission to unlock the bootloader. I flashed the "Global Developer" fastboot rom using MIFlash, which locked my bootloader. Then, I rebooted my device into fastboot mode and unlocked it using the MiFlash Unlock tool.

Press the unlock option in the tool.
Press reboot when the tool says.
Check the bootloader status under: Settings>> Additional settings>> Developer options>> Lock status.

Did you setup Mi account on the device after ROM flashed or just restarted to Fastboot after cleanboot?

Yes, I did setup MI account(the one on which I requested the permission) and synced it once before booting the device into the fastboot mode. Make sure to enable OEM unlock and USB debugging before fastboot.

did u also associate the xiaomi id with the phone under Mi unlock status in dev options?
It is another step which is failing on my device. It says it can't verify the device and ask me to retry after 1 or 2 minutes, forever.

I did not. Just logged in the MI account while setting up the rom on first boot.
I just tried official way to unlock my kate with global developer rom last night and I was very happy that it worked on first attempt.

TWRP is not working

Recently i had seen a post about how to port twrp recovery for a Qualcomm device, and i am having a LYF Wind 6 LS-5009 with 480X854 resolution and Qualcomm 210 with 1.2 ghz quad core. And i have ported a recovery for my device.
When i tried to boot that ported twrp img file through fastboot then after downloading it FAILED then i copied that ported twrp img to my sdcard and flashed through Flashify and it was successful but when i rebooted my device in to recovery mode then android boot logo appeared and a something written blinked for approx. 0.5 sec or more and i was unable to read that because it was too fast to catch from eyes and then i again restarted my phone again in recovery mode with another phone over the screen of my phone to shoot a video and i got a picture of that. Here is it
Can any one please help me to solve this issue?
And how can i successfully flash twrp in my phone?
Did you unlock the bootloader? Be sure to have a look at developer tools in celular config, mine has an option like "allow unlock bootloader" or something. And in adb shell the necessary command to unlock then is "fastboot oem unlock" .
Looks like your bootloader is locked and FRP is on.
Enable OEM Unlock from Developer options and unlock your bootloader.

FRP, not FAP.
Check Developer options and look for 'Enable OEM unlock' button.
Factory Reset Protection is a Google's security feature that prevent unauthorized users from resetting the device by forcing to sign-in into the same account as before being reset.

How to Relock bootloader

Hello
How to Relock bootloader for huawei mate 10 lite RNE-L21C185
Thanks
any answer
If it's anything like Mate 10 Pro, get into bootloader using adb or phones physical keys, confirm phone is connected to pc using 'fastboot devices' cmd, then type fastboot oem relock unlock_number. The unlock_number will be the number you used to unlock the bootloader in the first place.

Fastboot mode won't stay

I am trying to install stock firmware through fastboot. After typing below command,
Code:
adb reboot bootloader
the Device reboots but Fastboot mode only shows for 1 second then the Device reboots to system.
I have Usb debugging ON, OEM unlocking ON
Tried on 2 different PC's. Also tried removing Usb after command.
Reason for stock flashing is just that I used this ADB command on my phone and It lost IMEI: By this method and here is the detailed problem.
UPDATE: Took the phone to service center, they changed the Mainboard. But then Fingerprint was not working (couldn't enroll). They took it again and tried stock flash and fingerprint sensor change but the issue persists, still diagnosing.

My phone has lost Network service and IMEI is null. I did not root. I did this: Method
Does that mean I need to unlock bootloader to flash the stock ROM? Is there any other method? I don't want to lose warranty.
The phone does boot to EDL mode.

Can I achieve this without voiding my phones warranty?
I finally took the device to service center. And the executive said he would send the case to Realme and he is not certain that it would be covered under warranty as the imei is broken. But my device's bootloader is untouched and I never tried rooting.

Question Stuck in fastboot mode

Hello everybody,
My phone's battery died and I charged it. When I tried to turn it on, I saw this screen. I've tried clicking on the options but it's stuck in a loop and I don't understand what's happening.
If anyone has experienced this issue before, I'm reaching out for your help. Please assist me.
Flashing factory firmware in fastboot might be the only option. Doing such will wipe everything on your device though!

Since your bootloader is locked the only way to flash the OS is to sideload the Full OTA via ADB or use Pixel Flasher to sideload it. If you happen to have OEM Unlocking enabled in Developer Options you can use Android Flash Tool as that will unlock your bootloader as long as OEM Unlocking is enabled. If it isn't, sideloading the OTA will be the only way to reinstall your OS to hopefully get you out of this.

Oops! You are right, mate.
Hello so I am stuck here
When I go to Android Flash Tool it's says :
"Device Unlock Disabled​For security reasons, you need to enable "OEM unlocking" in order to flash your device. "
And when I tape in CMD the command "faastboot falshing unlock" it says
"FAILED (remote: 'flashing unlock is not allowed')
fastboot: error: Command failed"
Is there a way to unlock the devices states I have seen a video when
when a guy is using a unlock.bin he download at LG offcial site. Does Google have an alternative where can I download this type of file for my Pixel 6.
Google doesn't have an alternative. If you can't flash the OTA, and apparently you can't because OEM unlocking wasn't enabled in developer options, you need to get a hold of Google and explain your situation to them. You'll likely have to send it back to them, if able to do so.
You can't enable OEM unlock by fastboot/recovery.
Can you boot into recovery?
If yes, then this is your only way out!

Use image of OTA, not Full!

Unfortunately, it is not possible as my phone is showing that it is locked and I am unable to access the settings to unlock the OEM, since I am stuck in fastboot mode. Guess it's dead only if there is a way to unlock the OEM without going to setting.

You misunderstood!
You don't get to do anything from fastboot with OEM locked.
I asked if you can enter RECOVERY mode?
If yes, then visit the link I shared.
btw, why on earth you are flashing 'adb'?

Unfortunately, when I go into recovery mode, it keeps looping back to the original screen in an infinite loop.
I lost hope and went to a repair shop, but they told me to contact Google. The customer service will send me a package to return my phone. I didn't know that the OEM was so important, I will activate it next time. Tanks for your helps ...
