Hello good people.
I can't unlock the bootloader in any way. I've tried almost all the commands and tutorials on the internet. The device is not visible in the console in fastboot mode (blue LED) only in fastbootD mode. From the console with the command "adb reboot fastboot" I get fastbootD fastboot flash unlock command 0xA4B8..... I get an error every time fastboot: error: ANDROID_PRODUCT_OUT not set Maybe someone has an idea how to solve this?

Hi, so my Xiaomi MI A2 is kinda not working and I think that wiping cache partition might help but I can't access the recovery so I wanted to install TWRP. The thing is I have the boatloader locked, I have the USB depuration activated but not the OEM, so how can I unlock boatload or unlock OEM via fastboot?
Thanks

It won't let me. It says:
my command: fastboot oem unlock System: FAILED (remote "flashing unlock is not allowed")
Fastboot: error: command failed.
Same with the critical. I also had an error trying another command, it said, not allowed in lock mode.
Actually, I'm trying other commands and it's the same error with all comands.

Hello, I installed Havoc OS on my MI A2, but then an update was requested, I did the update, but when I rebooted the device, it did not start, I went into fastboot mode and I reinstalled the havoc. "androidOne" screen and nothing happens, now I have to enter fastboot mode with the command "fastboot boot twrp.img" and the error "failed to load / authentication boot image" appears, I tried flashing the rom stock using the MiFlash, and the cell phone persists with the same error, now my cell phone is with the bootloader locked and I do not know what to do

Thanks, I was able to repair after unlocking the bootloader again and then unlocking the critical parts, so I flashed a stock rom from August 2018, however didn't block the bootloader again.
I rooted my Note 8 and when I'm in the TWRP bootloader, I can issue adb commands, but no fastboot command (list of devices empty). How can I get the phone into a state where fastboot works?

Samsung doesn't use fastboot!
They lock it out in favor of their Odin flash tool.
so there's no way to use fastboot commands? There goes my hope on making it boot on power connect
Phone info
OPPO A74 5G
Model number - CPH2197
Build number - CPH2197_11_A.12
Android 11
Developer Mode enabled
OEM Unlock enabled
USB Debugging enabled
Below are screenshots of all of the above

Phone is recognised by ADB but not Fastboot and as such I cannot unlock the Bootloader. Is there something I've done wrong or something else I can try?
When entering "Fastboot devices" in CMD nothing comes up.
When entering command "ADB reboot Bootloader" in CMD the phone restarts instead of loading into Bootloader.
I have tried turning phone off and the pushing power button + vol up - this just keeps restarting phone.
Any help would be much appreciated as I'd really like to root this phone all extra info in images on Imgur. Link above.

Did you find a way? I tried everything but I couldn't get into fastboot
No way to enter fastboot mode for oppo phones. Now I use Oppo A74 4G version. Cannot enter fastboot mode. It's locked by Oppo. And they don't give bootloader code for unlock BL. Only way is to change phone
I've been trying run fastboot too. 4 hours later I find this thread. That explains it
Last Oppo phone I buy I guess.
Did you manage to find a workaround for this by chance?
Has anyone tried rebooting from recovery to then enter fastboor or?
Im gonna look into myself soon...
Ive seen this issue before on a different phone but cant remember how they bypassed it
Perhaps yall can try to find a post where they did so.. maybe it'll work on this phone too.
I was able too get to fastboot mode. The phone labels it "recoveryd mode", however, fastboot commands work.
1st. Connect phone and confirm ADB is connected by using "ADB devices" command.
2nd. Enter "adb reboot fastboot bootloader"
Phone will reboot into "recoveryd mode". It looks exactly like the normal recovery mode except the title displayed after you select the language and fastboot commands will work.
However, I still have not found out how to unlock the bootloader, so it does me no good.
try doing adb reboot fastboot or adb reboot bootloader
fastboot oem unlock
FAILED (remote: 'Unable to open fastboot HAL')
fastboot: error: Command failed
guys ,, fails
when trying to boot to fastboot and not fastbootd
My PC cannot detect my phone in fastboot mode. It always get stuck on <waiting for device> when enter command fastboot flashing unlock or any fastboot command. How can I fix this?
