Hello,
I'm trying to unlock the bootloader on my Oppo A 15 with ColorOS 7.
The developper mode, debugger usb and oem unlock are enabled.
I use the last adb fastboot platform tools.
I reboot my phone on recovery mode (there's no fastboot, or download mode or whatever), I then have a very short menu on my phone.
On my computer, fastboot detect the fastboot device but then, unlocking bootloader doesn't work.
Fastboot fastboot flashing unlock return the message "unable to open fastboot HAL"
There's not much I can do as a matter of fact. I tried several of the command In Here and most don't work.
The command "fastboot getvar all" gave me a sh...load of informations, but I don't know what I can do with it.
Any help?

i have the same problem and i didnt find anyway to fixit
Sticky Bit Fastboot
and here is the fix
First you want to download this zip file extract the file to your computer so it should read C:\Android
Next click on it once so it's selected hold left shift and right click and click on "open command window here"
Now plug in you phone and boot it up normally, then make sure usb debugging is enabled.
now in the command window type "adb devices" (this makes sure your device is hooked up and ready to be fixed)
List of commands to type in. ( in order)
1. adb reboot bootloader
2.fastboot oem fb_mode_set
3.fastboot oem fb_mode_clear
3.fastboot erase userdata
4.fastboot erase cache
5.fastboot reboot
download all the files from here

While Unlocking Bootloader, Fastboot Commands are stuck on "waiting for device"
I have a 6045I version Idol 3 and I've installed the 15 second adb fastboot setup. When I type the command "adb devices" I get the id number and rebooting to bootloader works fine. Once I reboot, the command fastboot -i 0x1bbb devices shows the id number. The problem is when I try either fastboot flashing unlock or fastboot oem unlock both result in the cmd saying "waiting for device". I don't know how to fix this but I've done some research and I think it might have something to do with drivers or maybe alcatel blocked fastboot after a certain update? All I want to do is flash the lineage rom to get android 7.1 nougat so I would really appreciate any help.
My me302kl can enter the fastboot mode, but it can't be unlock with any fastboot command!
I have already tried "fastboot oem unlock" and "fastboot flashing unlock", but it always showed the Failed unknown command!
Because I can't enter the main system, I can't install and use the official unlock bootloader apk.
Could any one help?
So, Iwas using Havoc Os 3.8 on my realme 5i, but I wanted to lock bootloader again, then I entered fastboot mode and locked bootloader, but I stucked in fastboot mode, It looped. Could not enter recovery or system. Only fastboot mode, because bootloader is locked I couldnt flash anything. I tried fastboot flashing unlock command but it did not work.
But solution was very easy, fastboot was not actually fastboot, everytime I power off device and power up there was not fastboot writing and robot icon, just directly fastboot itself. So actually it is fake fastboot, you just need to use volume buttons and select reboot to bootloader option, once device reboot you will see now fastboot- robot icon then fastboot itself, now you can unlock device with "fastboot flashing unlock_critical" command.
First, power off. Then wait for couple of minutes then start fastboot again.
