Hey!
I got a Zenfone 8 from a friend, and he told me that he tried to flash Lineage OS once, for some reason he got some errors and ended up going back to the stock ROM and relocking the bootloader.
Now I'm trying to unlock the bootloader again through the ASUS app, but it doesn't work. He tried to help me with some commands through fastboot mode and it also didn't work. There is any way to unlock it again after relocking it once?
He said he used the command 'fastboot oem asus-csc_lk' to relock it, don't know if it is hepful.
edit: We tried 'fastboot oem unlock' 'fastboot flashing unlock' (failed with permission error) and 'fastboot oem asus-unlock' (which resulted in FAILED (remote: 'Verify unlock token fail.')
Also AsusUnlock apk installs succesfully through ADB but fails to unlock with error 24802. Trying to install it through the phone doesn't work and gives me an error.
give more information please, from what build did your friend flash the lineageos? to what build did he go back to? did you install latest working ADB? are the drivers for the fastboot installed correctly? are you connected to the internet when trying to run the app on the phone?

He said he followed what was on the guide he found, first updated to Android 12, the latest on on asus website (WW-31.1004.0404.107), and then tried to flash LineageOS ROM, then he got some errors and went back to Android 12 and relocked the bootloader. He said he never tried anything again. When I got the phone it was on Android 12, I tried unlocking it as I said and it didn't work. Then I downgraded it to 11 using the firmware from asus website (Version Android 12 to Android 11), and tried to unlock it again using Android 11. Also didn't work.
About ADB and Fastboot drivers, they are correctly installed, tried some "standalone" versions and also the one that come with android SDK Platform Tools. Tested it on other devices and it worked well. And the phone was connected to the internet when I tried using the app, I'm sure because I downloaded it on the phone aswell, using the browser.
edit: Actually I'm not sure about the fastboot drivers, I've just downloaded the sdk tools from google website.
what lineageos did he flasah? if its 18.1 thats android 11... propably why he got the errors.

That's probably it. But there's any way to unlock the bootloader again so I can give it another try?

The warning appears, but it is not unlocked. Every command fails, device-info says that my device is not unlocked., it is locked.
What I'm trying to do is unlock it.
Let me try to explain what happened again.
The phone has been unlocked to install LineageOS. It didn't work. The past owner then installed the stock rom and locked it using this command: 'fastboot oem asus-csc_lk'.
Then I bought the phone from him, and now I'm trying to unlock it again, but it doesn't work.
The question then is: Is it possible to unlock a phone that has previously been unlocked and then relocked?
Hey, did you got it to work ?

Hello,
I tried to unlock my bootloader several times.I followed every guide and didn't make it.I have LBL xperia sp (Allowed bootloader unlocking :No)But i read i can try it anyway.So the problem here is when i start cmd in abd folder and enter command fastboot -i 0x0fce oem unlock 0xmykey it says waiting for device.I installed drivers from the guide.Because i have windows 10 i disabled driver signature and all driver are installed.I tried all ports on my laptop and volume up,down.It just wont enter fastboot skips to sony logo immediately.Recovery is working fine.
Now i don't know is it because i have (Allowed bootloader unlocking :No) or i am doing something wrong,also i tried with 4.3,4.4 and 5.0 android versions.
I searched for this problem on xda forums but couldn't find any help.
Thanks.

Your unlocking bootloader allow is no.
You cannot unlock your bootloader.

Can you check if your bootloader can really be unlocked? Back on stock ROM, open Dialer, then type in *#*#SERVICE#*#* and report your "bootloader unlock allowed" status.
"Allowed bootloader unlocking : No" But i read somewhere i can still try to unlock it.

this thread has continued to be unaswered for several years now.
only tested 2 phones... and it seems they both have bootloader status is unknown. i can do fastboot and recovery mode on the 2 phones but on fastboot mode.. only shows blank screen... idk why it's like that. i downgraded both phones to 12.2.0 version. and bootloader status is still unknown. it can be recognized by the computer in fastboot mode using fastboot devices command but you can't do anything to it. fastboot oem device-info does not work only shows .......... , fastboot oem unlock ....., only one working is fastboot adb_enable .. kinda useless. .. i gave up on unlocking the bootloader for this phone.. im too noob for this.

I opened this thread when I was still "noob-ish". The device's bootloader can't be unlocked. Unless someone hacks into it's bootloader (like LG L Fino), it might be possible.

I got root access with KingRoot and then flashed TWRP with Flashify.
Somehow that gave me access to bootloader without the necessity to downgrade the firmware.
Short story: my phone bootloops (shows the Android One screen for 3 seconds, then reboots), and I cannot unlock the flash in fastboot. fastboot oem unlock fails, fastboot flashing unlock fails, fastboot flashing critical_unlock fails.
What can I do, is my phone definitely bricked?
Long story: I installed september OTA and then rooted with Magisk using the image patch method. Now I wanted to get October OTA, so uninstalled Magisk to recover the unpatched bootloader, but the OTA refused to install. So I tried the flash_all method, but it failed because I did not do the critical unlock. So I tried the fastboot flash critical_unlock, but it continuously refused to work.
So I decided to agan lock flash, and do the oem lock, to restart the unlock procedure from the beginning. But after locking, the phone does not boot anymore (and it was booting fine before!). On top of that, I cannot oem unlock anymore, fastboot oem unlock always fails.
Is there any way to recover the phone?
Try fastboot oem edl
then use mi flash
Thanks for help.
Unfortunately fastboot oem edl fails:
Code:
# fastboot oem edl
FAILED (remote: Device is already locked!)
Finished. Total time: 0.001s
And as fastboot oem unlock also fails, I cannot unlock the bootloader.

I'll need more info than that
what's the error you get when using oem unlock or unlock_critical?
are you using minimal adb? If so, don't, use this instead https://developer.android.com/studio/releases/platform-tools
Are you using a usb 3.0 port? Switch to a usb 2.0 if you are
I am working from Linux, and I have the full Android Studio installed. I cannot use adb, since I cannot boot the phone (and as far as I know, adb does not work on fastboot, but I might be wrong).
I will try with the one you linked and come back with the results.

Minimal adb includes fastboot, if you have minimal adb or you installed it from the repo then it's outdated, use the one I linked
Nothing was working for me, so finally I recovered the phone by opening it and using the deep flash method.
Hi guys,
Accidentally, im locked the bootloader of my moto z3 play and i cant boot because a previous bad installation that results in a bootloop.
I cant unlock from fastboot because the acctual system is new but unbootable (usb debugging and oem unlock disable by default...
I saw that there is some toolkits for many brands and models to fix this...
Will there be any for moto z3 play? or any other way to fix this brick?
I can access fastboot and stock recovery... Can i flash anything from adb sideload?
ty in advance

You should be able to reflash the firmware
Use
Code:
fastboot getvar all

I forgot to say that i ran by mistake flashing lock command, in way that oem is lock AND flashing too.
I have tried many times flash stock 9.0 firmware, but most part of lines out are permission denied (cause of flashing locked, i guess...)
After try flash, i get only bootloop and stock recovery.
I even already try apply update from adb sideloa to twrp or cwm but doesnt work (((
Plus, i try TOO boot on edl mode to use blank flash but doenst work, going to fastboot reason qcom boot failed ! ((((((((
I suppose can reflash the firmware with flashing locked? I have tried one of these beckham 9.0... I confess that not tried all of them.

Unlocking your Bootloader, you know where you enter that long code from the email that Motorola sent you.
I say this because sometimes people think, unlocking in the Dev-options, is actually unlocking the BL, when it's not.
Nor is a carrier unlock the same thing.
Your bootloader sounds locked from your Description of "access denied" errors.
I just want you to clearify that you are actually unlocked.

Although you're on Z3, this problem is generic. Ask in the Z2 forum, as they are more active. I also think the G-series (or other popular Moto phones) forums could help you with this.
Can you get to the recovery menu, and wipe factory reset (BL->recovery, up+pwr, Wipe/Factory restore)?
?

Ty for the advice... I will do that.
Yea, i can wipe data/factory reset, but its the same. Bootloop until stuck to "fastboot reason: fall-through from normal boot mode."
I've read about this scenario for months on several different model forums and I imagine my best chance is to use the blankflash in edl mode but i can't boot into edl mode. Wherever I connect it is always recognized as a Motorola PCS or Motorola ADB device. I'm thinking of buying the deep flash cable and see if it works ...
$ fastboot getvar current-slot
//Getting and setting the slot should not cause any harm, but you never know.
$ fastboot --set-active=<a/b - whichever "current-slot" isn't.>
$ fastboot reboot
EDIT0:
In addition, you should plan ahead if you do get in. Like doing everything it takes to allow you to unlock/flash (adb).
You don't want to miss anything critical and screw up that other slot too.

To everyone who is having this problem, just run the command multiple times in a row and it works! I don't know why, but just running it a few times in a row (I had to do like 9 times) gave me the unlock code.
Same thing for applying the code after getting it from Moto. Had to do it like 9 times in a row again, but it worked.
Hi there,
I just bought a pixel 5 phone and tried to unlock bootloader
After I made the steps described in that post for P5 ... after flasing the magisk img file I wanted to reboot the phone but it is stuck on the message:
"Your device is corrupt. It can't be trusted and may not work properly.
Visit this link on another device.

What can I do to fix that issue? I'm trying to root it and install lineageos after.
Regards,
LE: Most probably I run the command with fastboot installed with apt in ubuntu 20
Version from fastboot from ubuntu: fastboot version 1:8.1.0+r23-5ubuntu2
LEE:
Pfiu ... I was pretty scared ... fixed it with this link: https://flash.android.com/devices
Can somebody let me know please if the issue was because of the bad fastboot version?
Also ... I saw there is a kddi version and without it ... tried without kddi as I don't know exactly to verify if I'm having kddi

What's the problem? The message appears on some devices that had their bootloader unlocked. So the message alone does not matter.
The problem is that I don't have root access and I want to try again those steps for root

I want to make the steps described for how to unlock the bootloader and have root permissions as I want to install then lineageos on the phone
Thank you

So I was able to see again the device in fastboot (enabled stay awake)

Pull down your notifications and allow USB debugging after plugging in on your PC perhaps? Also check the box to always allow.
I don't try anymore to root my phone as I don't want to use lineageos custom rom. I already installed one that doesn't need root.
Thanks
LE: What I installed without root required had issue for me with sim manager
I finally rooted my phone and installed lineageos that is working well
