How do I flashback a ROM in bootloader mode?

Just like in normal mode.

turn off the phone then press and hold camera button then plug usb... then follow kahoes instruction...

Whenever I start the SDA unlock it says to connect my SDA, but it is connected.

You cant unlock in bootloader mode, you need to get at least a WM5 ROM, then unlock it

Greetings...
I will try to help you...
First, you have to enable the Developer mode on your device, going to Settings >> About Phone >>> Software Information >>> Build Number. When you reach there, tap on it about 6-7 times until you get a message saying you unlocked the Developer's Mode.

Then you will have to go back to Settings again and look for Developer's mode at the bottom of the list.
When you get into this option, you will have to search for Enable USB Debugging and OEM Unlock options, so you will be able to proceed to the unlocking bootloader...
You must activate both, otherwise it will not show on the pre-download screen! If you get a popup warning, tap enable if you would like to proceed.
Now restart your device into Download mode, pressing Vol Up+Vol Down+Power Button or just Vol Up+Vol Down and insert your usb cable into the device. The usb cable must be connected on your computer first.

After doing this, your device will go on Download mode and this screen will appear, pay attention carefully before press any key on you device....
After you do this procedure to press and hold Volume UP button, then it will show you another screen, like this...
Now you press Vol Up to unlock or Vol Down to give up and go back to normal.
If you choose Yes, your device will reboot and then will erase all informations and files you had into your phone and will perform a hard reset to factory default, and your bootloader will be unlocked.
If all were done correctly, this is the screen that will show for you from now on...
You're done. Your device is completely unlocked.
In any case, always have an original stock rom firmware of your device, so you can restore the original.
And if you want to lock it again, do the same steps again, but when you choose YES, it will do a hard reset again and go to factory install, erasing all again.
Remember to do a back-up of all your data and stuffs before you perform this.
I hope I had helped with this.

No option to unlock bootloader?

I want to root my phone with Magisk, so, following the instructions here:
I enabled OEM unlocking on my SM-A516B (European, not US or Canada and it's running the latest offical software (Android 12)) and rebooted to download mode via adb (goes to a "fastboot" mode when I select bootloader mode from recovery mode), but I don't see any option to unlock the bootloader. The English text on the screen says only:
Code:
Downloading...
Do not turn off target
Do not disconnect the USB cable during the software update!
Volume Down Key + Side key for more than 7 secs
:Cancel (restart phone)
There is also some Korean text, a DID code and a barcode. Holding volume up does nothing.
I'd seriously appreciate any ideas on how to proceed!

So I found the solution for myself: I don't want to go to the download mode, but instead hold valume + and - and plug in a USB cable.
