Hello,
I have problems with my Lenovo tablet Tab S8-50F. During deleting file via PC tablet froze and then I have stuck on bootloope.
I tried flash stock rom TABS8-50F_WIFI_ROW_USER_SEC_ENABLE_WW14_S000143_140929 K.K. with Intel Phone Flash Tool it stops at 27% and failt at the command fastboot oem sections /tmp/partition.tbl failed (remote: GPT command failed)
Then I googled and it is possible that it has locked bootloader. So I tried the command "fastboot oem unlock" - error command was found, then tried another command , "fastboot flashing unlock" the console looks like working .. but in the tablet is error unknown command "flashing unlock"
I am really stucked.
Does anyone have any advice ?
Thank you

You can use "fastboot getvar all" cmd to check whether ur boot loader is locked
Dear all,
I have made numerous attempts to unlock the bootloader of my Wiko U Feel Prime, but to no avail.
(My goal is to flash TWRP, root with Magisk and install LineageOS.)
USB debugging and OEM unlocking are enabled in the developer settings.
ADB recognises the device. When I execute adb reboot bootloader, the device reboots, and doesn't get past the "powered by Android" screen – but is nonetheless found by fastboot when I run fastboot devices. Seems like the USB drivers are functioning properly, correct?
Now, when I run fastboot oem unlock, I get the following response:
Code:
...
FAILED (remote: unknown command)
finished. total time: -0.000s
The command fastboot flashing unlock gives the same result.
Moreover, fastboot getvar all displays no unlocked variable. The command fastboot getvar unlocked yields
Code:
unlocked:
By the way, this phone was shipped SIM unlocked.
I've spent hours looking around the web for solutions, but everyone (including guides specifically written for Wiko U Feel Prime) simply says "unlock the bootloader" as if it's a trivial task. And I've run out of ideas. Could anyone help?
Thank you very much.
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

how do I go about something like that? I would only like to be on official software so how will I not be able to receive updates?

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!
DISCLAIMER:
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!
Hey so I installed adb and ran the phone under fastboot but when I run fastboot oem lock all it says in the windows powershell is < waiting for any device >

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?
Also, I've noticed some steps are not clear (and one is doubled), I'll clean it

Try all the two, I don't remember which one works (I think the Composite worked for me), but try also with the other ones
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?

It's not working for me, please help:
C:\platform-tools>fastboot devices

C:\platform-tools>fastboot oem lock
FAILED (remote: 'Command not supported in default implementation')
fastboot: error: Command failed
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:
Bash:
fastboot oem asus-back

As mentioned here check if you have enabled Debug USB and OEM unlock in developer options and try to reboot into bootloader (with either fastboot reboot bootloader or adb reboot bootloader)

@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)
I'm currently trying to unlock the bootloader on my Tecno Spark 8C, model KG5K. A fairly new phone brand, so documents regarding this is really shallow.
So I opted for ways that are supported on a variety of Android phones instead. I've used every way possible that I can find. ADB, Magisk, TWRP,... but none has worked, because of one sole reason: the Fastboot. So, essentially what is happening to the Fastboot is that it's seems to be missing a LOT of typical features in a Fastboot, like flashing unlock and OEM unlock.
I tried turning on OEM unlock in settings and made sure USB debugging is enabled, disabled all of the security features and even checked if my phone is ALWAYS transferring files to my laptop, but nothing is phasing the Fastboot unknown command and unlock bootloader failed error messages.
The only imaginative option that I can think of now, is whether if I can update/replace the original Fastboot that came with my phone, but I can't explain it in technical terms, or even know if such a method existed.
I would appreciate all the help I can, thanks to all of you in advance.

In fastboot mode, is your phone recognised with a random string of numbers or alpha-numeric characters? If not, you may lack the fastboot drivers which are distinct from adb drivers. Please install the Platform Tools from this link and try.

If that is the response to the 'Fastboot devices' command and the same is shown when you issue the 'adb devices' command (while in adb mode) then you have no driver issue. What about the Platform Tools that you use (you said that several commands were missing), did you try the one I linked?
Further, the bootloader unlock command varies between devices and what works for one model may not work for another. You have to search for the proper command for your device.
Code:
C:\>fastboot devices
C:\>fastboot getvar version
C:\>fastboot getvar all

I tried the commands, but one stood out because of the output it given. Fastboot getvar all returned nothing for all. And I did try the official Android platform-tools, but it's still the same results, I'm afraid.
Beside that, getvar version given a 1.0 version. Checked the device ID on both modes, they're the same.
Also, I did extensively search for any sliver of documentation on the fastboot of this device, but I basically got nothing, since this device is still fairly new.
Fastboot is a bit of a weird animal.
The desktop executable knows valid commands and will not even attempt something that it doesn't know.
Code:
C:\>fastboot fishheads
fastboot: usage: unknown command fishheads
C:\>fastboot oem fishheads
FAILED (remote: 'unknown command')
fastboot: error: Command failed
C:\>fastboot erase fishheads
Erasing 'fishheads' FAILED (remote: 'Check device console.')
fastboot: error: Command failed
The first error is local, the second one is remote because the desktop knows "oem" is good and doesn't care after that.
The third fails on no partition called "fishheads", but it tried. Try that and these:
Code:
C:\>fastboot getvar product
C:\>fastboot getvar serial
C:\>fastboot getvar unlocked
C:\>fastboot getvar variant
C:\>fastboot getvar partition-size:boot
C:\>fastboot getvar partition-size:boot_a
C:\>fastboot getvar partition-size:boot_b

@mayberandomparable
Did you try 'fastboot flashing unlock' command or 'fastboot oem unlock' command? If all such commands fail, you may need a special unlock zip file which seems to be available for the 8 Pro model but not for yours (https://forum.xda-developers.com/t/twrp-for-tecno-spark-8-pro-kg8-root-other-guide.4477425/).

So, is this operation possible?
It could be that the OEM unlocking in Android Settings is broken/ineffective.
It could be that the fastboot needs some oem command.
Like (hypothetically) fastboot oem secret-unlocking-command pwd12345
Now, if you had a copy of abl we could reverse engineer it.
Have you tried to see if you can reach fastbootd? That's the user space fastboot that's in some Android.
Check if there is a difference between adb reboot bootloader and adb reboot fastboot
Is this a Qualcomm thing? Have you tried EDL? adb reboot edl

Hardly a Qualcomm thing, since this is using UNISOC.
Also, yes, it does have a fastbootd mode. Found on a whim!
Edit: Just tried EDL, sent straight back to the regular reboot command.
So... Does this other fastboot react at all differently?
