Maybe you find something more in the specific forum for the "old" A series on here https://forum.xda-developers.com/f/galaxy-a3-a5-a7-a8-a9-android-development.4857/
Regarding the fastboot commands you are trying to execute, this model doesn't support fastboot, the OEM unlock won't work at all.

Unable to re-lock nexus-s through fastboot

i'm in the process of re-locking my bootloader in order to send it to Samsung for repair (home button not working). when i run the command line "fastboot oem lock", it just keeps hanging at "waiting on device" and nothing happens. i have the correct drivers installed. when i run "adb devices", it shows up the device. however, when i run "fastboot devices", it does not show up anything. any help on relocking my bootloader would be appreciated. Thanks!
Probably shouldn't be answering this here buuuuut...
adb reboot bootloader
and THEN
fastboot oem lock.
See what happens. You have to be in boot loader mode. Please move your questions to the Q&A section sir.
i did enter that command in order to get into fastboot. after that , i ran the command "fastboot oem lock" but it gets stuck at "waiting on device"
Update your drivers
Yea at this point I'd say its a connectivity problem. Drivers and or cable, but since you are getting adb devices to recognize, its not your cable. You should really use ubuntu, you would save yourself a lot of time, because you don't really have to deal with drivers like windows.
'sudo fastboot oem lock'
You need to be super user.
sure you went into bootloader and not recovery? because adb is seen in recovery and doesnt work in bootloader!

Stuck after unlocking bootloader?

Hi everyone,
Today I decided to root my Mate 9.
I started out with turning 'OEM unlock' on and usb debugging. With ADB installed and the huawei drivers, I began to unlock my bootloader. On the 'EMUI Huawei' homepage I filled out my device details and obtained an unlock code. I opened ADB and checked with 'adb devices' if my device was there. It was. So I continued with typing 'adb reboot bootlader'. After that I typed 'fastboot devices'. My device was still showing up. I typed 'fastboot oem unlock CODE (with the code). On my screen I pressed 'Yes'. Bootloader unlocked.
After this step I tried to flash twrp with the command 'fastboot flash recovery xxxx.img'. I couldn't continue because every adb/fastboot command keeps failing (remote: command not allowed). Now when I boot up my phone it shows 'your device has been unlocked and can't be trusted'. Phone=unlocked, FRP=locked. I can't do anything.
Device: Mate 9 L29C432B198
What did I do wrong or what did I missed? :crying:
I had this issue at first to had to redownload the original rom via the phone recovery this will fix the frp lock then u have to unlock and flash twrp 3.1.01 that is linked in the threads on here
Did it format after it unlocked?
You can try fastboot oem relock UNLOCKCODE
Then go to Settings -> Dev options -> enable OEM Unlocking
Then unlock again.
It probably will fail though if FRP is locked, but worth a shot.
Edit: It's supposed to say
PHONE Unlocked FRP Unlock

Fastboot access denied

I posted this in the appropriate forum but this phone is so old I've not received any response.
So I've decided to root and customize my Z2 Force and want to unlock the bootloader to get TWRP installed. All device side settings are correct (USB Debug, OEM unlock etc.) in developer mode. ADB commands are working fine as I can see my SN when using ADB Devices command. I then reboot to the bootloader through ADB (adb reboot bootloader) and it works fine and my Z2 boots into the bootloader. Then I try to get the unlock code (fastboot oem unlock) and I get a message after trying to run the command: access denied. I started my CMD window using run as admin - no help. Installed ADB all over again with new generic drivers and moto drivers - no help. Even installed everything in the root directory on my hard drive - no help
I don't understand why I'm getting this message. I've unlocked and rooted all my phones over the years but they've all been HTC. Never messed with a moto phone before. Anyone think this is a permalocked bootloader version - MODEL:XT1789-04 TYPE:M29E2
Things I have not tried yet:
Another computer
Tested fastboot command on one of my other phones
Any help is appreciated.

The process to unlock a moto phone is a bit different. OEM commands are as it says, defined by the OEM. They need to be precise and functional. The command:
Code:
fastboot oem unlock
alone will not work.
Step1:
Instead, You should enter:
Code:
fastboot oem get_unlock_data
You will get an unique 131 ID string that looks for example like this:
Code:
(bootloader) 0000000000000000000000000000001
(bootloader) 0000000000000000000000000000002
(bootloader) 0000000000000000000000000000003
(bootloader) 0000000000000000000000000000004
(bootloader) 0000005
Copy the output to a text editor and delete the (bootloader) and the spaces in between, so it's one whole string.
Step2:
Visit the official Moto unlock website. Sign-in with your account, you will be using the E-mail used to create said account to receive the unlock key. Paste the edited 131 ID string and click Can my device be unlocked? button. If it is unlockable, then a conformation page will appear asking for consent and warranty bla bla bla.... Just read it and accept.
Step3:
When you click unlock, you will receive a KEY through your E-mail attached to the moto account used. Save that E-mail somewhere offline, as it can be used to re-unlock the bootloader in the future if you relock it. Connect your device in fastboot again and type:
Code:
fastboot oem unlock KEY
Where KEY is the one you got in the E-mail.
Done!!! Enjoy your freedom , also check the mark near my answer if it solved your question so others don't have to search for long.
Thanks for your reply. Yes I wrote the fastboot command wrong in my post.
The problem I'm having is even when using the fastboot command you posted I still get "access denied" when using fastboot commands. ADB works fine allowing me to reboot into the bootloader through the command prompt/USB as in ADB devices.

As long as in Android -> Settings -> Developer options the option "OEM unlock" isn't got enabled - and phone got rebooted afterwards - you receive the reported error.
OEM unlocking is turned on in developer settings
I'll post up some screenshots soon. Right now I'm on day three of work on the 12 hour night shift.

If you don't see the OEM unlock setting in developer options then there isn't anything you can do to unlock the device.
What's the Baseband Version on the device? You can find that under Settings-->About-->Software Information

Pc can't communicate when in bootloader(tried everything)....

I just purchased a OnePlus Nord N10 5G (BE2026)
Originally it was running OxygenOs 10.x.x.x
Following guides from oneplus website and here on XDA I was able to successfully unlock the bootloader and of course ADB worked fine as well as Fastboot in the bootloader etc...
After unlocking the bootloader I realized that OxygenOs 11.0.2.BE86AA was available via OTA. Which is now what the phone is currently running.
***MAIN ISSUE***
after unlocking the bootloader in order to gain root access via TWRP and Magisk my PC fails to find any devices while the phone is in Fastboot mode... ADB still works just fine but as soon as I run "adb reboot bootloader" or boot to bootloader via buttons the PC will not detect the phone any longer while in the bootloader or Fastboot mode...
I have triple checked that:
SDK USB drivers
ONEPLUS USB DRIVERS
Windows Universal USB drivers
USB Debugging
OEM Unlocking
PC is granted developer access
newest version of ADB & Fastboot
and everything else I can find on this issue searching Google & XDA for the past 3 days
* one issue that I found strange, only when the phone was booted into the bootloader Windows device manager showed Android as an unknown device. Which I could only solve by using Zadig and installing Winusb driver... but still running "fastboot devices" while phone is in bootloader / Fastboot mode still shows no devices....
I've been trying to solve this about 4 days now scouring the internet for any information I could find and nothing seems to work. But everything worked just fine before I unlocked the bootloader / flashed OxygenOs 11 via OTA and now windows to see the phone while in the bootloader....
When phone is got booted into bootloader / fastboot mode then phone can't get seen / accessed by ADB. Point.

@jwoegerbauer not entirely sure what you are trying to imply with your message...
If you are trying to point out that ADB doesn't work in bootloader / fastboot mode, I am completely aware of this. And never mentioned otherwise in my original message.
With my phone booted up into Android
And I run "adb fastboot bootloader" the phone will reboot into bootloader mode but my PC still shows waiting for devices... Or if I boot into bootloader / fastboot mode manually and run “fastboot devices" it shows no connected devices. And no fastboot Commands work either... I am not trying to run ADB Commands in fastboot mode.
AFAIK starting with Android 10 the command sequence should be as this
Code:
adb devices
adb reboot fastboot
fastboot reboot fastboot
fastboot devices
...
fastboot reboot
because fastbootd got moved to Android's userspace.
