Hey guys, I Need some help, I'm trying to unlock bootloader, but my device doesn't recognize fastboot commands like "fastboot oem get_unlock_data" Or "fastboot oem flashing_unlock", why?
Ps: Motorola drivers ok, usb cable ok, oem unlock and usb debugging ok
Error: FAILED (remote: 'unknown command' )

There is a way, but you have to wait for Motorola to make this year's USB drivers available: this is how you enter the adb folder and rename the incone mfastboot to fastboot done this in the control panel Or on powershel you put it
.\fastboot oem get_unlock_data.
This appears on my <waiting for device> even though I installed the drivers But last year, so I think we should expect Motorola to make this year's USB drivers available
I'm having trouble even getting it to prompt for usb debugging authorisation. I'v got adb &fastboot, I've enabled dev options and usb debugging but when I connect it via data cable it doesn't prompt for authorisation.
I am thinking maybe a driver issue but I can't seem to find the drivers anywhere.
Any ideas/help? would be much appreciated.
According to this

this commnad
fastboot flashing unlock_critical
will unlock. Is this true?

short anwer: no
long answer: maybe?
for that i read you might want to proceed with a factory-reset and block any update. in this way, that command will work. honestly i gave a try to it, but nothing changed. the smartphone is pretty good, why the hell did Motorola want to prevent such actions? i don't understand that yet.
I have been trying to unlock bootloader on my Realme 3 Pro, but as soon as I enter the command in fastboot mode, it shows the following error:
PS D:\realme\platform-tools_r29.0.6-windows\platform-tools> ./fastboot flashing unlock
FAILED (Write to device failed (Unknown error))
fastboot: error: Command failed
But the device is being detected by my laptop..
PS D:\realme\platform-tools_r29.0.6-windows\platform-tools> ./fastboot devices
51a8ba49 fastboot
The customer service team is also unable to sort it out.
Your help will be truly appreciated!

also given that command and also
fastboot flashing unlock
so what was the error message then
seems unlocking is disabled in aboot therefore no common unlock method will work. at least there is a working firehose programmer for that device, so you can dump boot.img off the eMMC and try to modify with AIK and Magisk (AVBv2 signing required)

I bought the Asus ZenFone 8 Flip with the bootloader unlocked, it is not running a custom ROM. How do I lock the bootloader? Thank you
Try this with fastboot:
fastboot oem lock
However, this won't restore your warranty and you won't receive updates, since surely who has unlocked your device has used the official bootloader unlock tool which registers your serial number

You won't get OTA updates, but you can still update manually downloading the zip from Asus website.
Unfortunately that's the price if you unlock the device (not only for Asus, a lot of other manufacturers (i.e. Sony) do this too)

interesting... So I don't know how to lock the bootloader precisely. So I download the latest firmware from the Asus website, plug the phone into the computer run fastboot then what? Am I missing something?

No, just follow these steps:
Make a backup of your phone!! Unlocking/Locking the bootloader erases all your data partition (so all your stuff will be gone!)
Install ADB on your PC if you don't have it (check how to install it: https://www.xda-developers.com/install-adb-windows-macos-linux/).
Plug in your device via USB with Debug USB setting enabled (in Developer Settings)
Open a terminal prompt on your PC
In the terminal run adb devices. If you see your device I the list then you're fine. Otherwise, you have mistaken something in the previous steps.
Run adb reboot fastboot (or adb reboot bootloader if it doesn't work) to reboot into fastboot mode
Run fastboot oem lock to lock the bootloader
Run fastboot reboot to reboot the system
Your device is now locked!

I'm not responsible of any data loss, damages and/or bricks you make to your device(s) by following this guide!

To update the system when a new version is out, since you won't receive OTAs:
Go to Zenfone 8 Flip support page: https://www.asus.com/Mobile/Phones/ZenFone/Zenfone-8-Flip/HelpDesk_Download/
Choose Android as OS and scroll down to "Firmware"
Download the latest zip
Put it in the internal storage (in the root directory, not inside another folder!)
Two paths:
If you put the zip from PC via USB simply unplug the USB cable
If you downloaded the zip and put it manually via file manager from the phone reboot the system
A notification should pop out, notifying you there is a firmware package to install!
Just follow the notification message and you'll be done!

Oh that's an issue I have all the times with Asus devices. There's a simple one-time fix though: just install the official Asus ADB drivers.
Download them from this page (I know it's the smaller Zenfone 8 page, but they work with every Asus device): https://www.asus.com/it/Mobile/Phones/ZenFone/Zenfone-8/HelpDesk_Download/
Choose your windows version (for 10 and 11 choose 8.1)
Download the USB driver
Extract the archive somewhere in your PC
Open Device manager in your PC (search it in start menu) while the phone is connected via USB and in fastboot mode
You'll notice an unknown device with a yellow/orange warning icon at the top of the devices list. Right click on it and choose Update drivers.
Choose "Search driver in the PC" (the second option (don't choose the first one since it searches the driver automatically on Windows update))
Choose the folder you extracted
Click "Next"
Drivers should be installed and fastboot should recognize your device (to test run the command: fastboot devices)
Sorry for the late reply, but I didn't get any notification from XDA
there were two options for drivers android adb and android composite adb drivers I selected the composite one but it doesn't seem like it was installed

When I try to update the drivers it says that windows was unable to install your and then it says the device.

Do you installed the drivers when the phone is in fastboot mode?

Hi,
I've bought a second hand zenfone 8 flip. After Hard Reset I have to enter the old PIN to continue. The problem is the seller doesn't have the PIN and is not willing to take the phone back. ASUS is not willing to help because I bought it second hand.
I already flashed with raw firmware, but this is still coming up.
Any ideas? Should I start a new thread?

So, as you can see, the driver is installed correctly as I get an answer from fastboot devices, but then the OEM lock doesn't work.
Are there any other ways to re-lock it?
Thank you!

@wyktron can you try this? This worked with my Zenfone 6 some years ago, it might be the same for ZF8 Flip, due to Asus customization:

@maicol07 there's no OEM unlock in my developer options, only the USB debugging (which is already on)
besides this oem method, is there another way to lock it? perhaps through the zenfone flash tool (I have it installed and it detects my phone, but never used it)
first of i apologise if i have bad english
ok so i had this device for some time and decited to root it (my first time rooting a phone). And i need to unlock bootloader to flash stuff and i have all necessary things on my pc (platform tools,drivers,) everything seems to be working but as soon as i get into bootloader the only command that works is "fastboot devices" Any other commands dont work. I tried everything online and this is my only other thing left to do. I've been researching for 2 days at this point and i am almost certain that the commands are disabled by the company itself (like huawei) did anybody else ever root/unlock bootloader for this device because i didnt find any actual root guide for the particular device (besides from the auto generated ones like https://rootguia.com/how-to-flash-caterpillar-cat-s31/ https://mobilewithdrivers.com/unlock-bootloader/cat-s31-16gb-2gb-ram )
The exact error is:
FAILED (remote: 'unknown command')
fastboot: error: Command failed
(and this error is for every single command that uses fastboot besides from fastboot devices. Adb works just fine)
I tried:
reinstalling drivers
installing drivers that are "prepared" for the cat s31
changing cable
changing port to usb 2.0
reinstalling platform tools (from official google site)
checking device manager for the device (it shows up as android bootloader interface)
trying alternative oem unlock commands (fastboot oem unlock, fastboot flashing unlock and 2 other commands that i cant remember rn)
having oem unlocking and usb debugging enabled from the developer options
in my opinion the only explanation is the commands being disabled by default and even if it was it wouldnt be known if it was since most people dont root or purchase this device
please help me out here

Never mind. anyway, if you dump phone in edl mode (or download stock ROM somewhere else) you can search aboot for device specific fastboot oem commands

There are many hidden fastboot commands on your device. In order to find them, we will need to dump the bootloader and examine the contents!

sooo turns out win11 strings commands are kinda different or broken (probably not im just dumb) i just used notepad with ctrl+f and couldnt find anything besides the text that says are you sure you want to unlock bootloader but that is probably not related since i didnt find any commands or anything. So im actually going to attach the emmc_appsboot.mbn i know it looks sketchy you dont have to download it its totally understandable but if you do please do give it a check and respond. I want to get this done one way or another its 1 am i want to sleep ;(
could it be true that they made a truly un unlockable unrootable device
I had a look but there are no fastboot commands in it. However "oem unlock" is mentioned, so the usual fastboot oem unlock should work.
maybe there is more in secondary bootloader sbl1.mbn

from recovery using the flash firmware with adb option??
edit: i meant apply update from adb
edit2: what if i hard reset from recovery would that reset the firmware?
edl firmware cannot flashed from recovery. power off phone, press both volume keys and plug in usb-cable. check VID/PID from windows device manager. if you see device ID (05c6:9008) the phone is in EDL mode. you can now use EDL tool (post #2) and backup current ROM. then you can flash other ROM.
