Hello everyone, I was in China recently, and bought my OPO there. Therefore, it came with colorOS.
I wanted to change it to the rom to SlimSaber. Unfortunately, I've been unable to do so.
To unlock the bootloader I'm using this set of instructions:
[GUIDE] OnePlus One - How to Unlock Bootloader, Install Custom Recovery and Root - http://forum.xda-developers.com/showthread.php?t=2788632
I think my problem is while unlocking the bootloader. I get into fastboot mode, and using the android-sdk devices I'm able to get the serial number of the phone.
But, when I run the fastboot OEM unlock, nothing happens. Everything should be erased, right? Well, that doesn't happen. After that, I enable the USB debugging, but after, when I'm supposed to disable the 'Updater recovery with system updates' I simply don't see that option.
Can anyone help me? Do you need any more info?
Tanks in advance;

Hi everybody!
After the precious advice of user ndt192, I managed to unlock my SKR-A0 which, until this day, seemed un-unlockable.
THIS PROCEDURE WILL WIPE YOUR PHONE MEMORY SO REMEMBER TO BACKUP EVERYTHING
TL;DR
In developer options, OEM Unlocking must be ticked (if present), then I just issued a fastboot oem unlock while in fastboot mode.
I'm on the latest OTA (29-12-18, v. G66X1812291CN00MPX).
Full Tutorial
Enable developer options by tapping 7+ times on Settings -> About Phone -> Build Number
Enable USB Debugging and OEM Unlocking (if present) in Developer Options (Settings -> Other Settings -> Advanced Settings -> Developer Options)
Open a terminal and issue the command adb devices
On the phone, allow the access from your computer on the dialog that will be shown
In terminal adb reboot bootloader
Wait for the phone to reboot in bootloader mode
STOP AND THINK - DID YOU BACKUP EVERYTHING?
Issue the command fastboot oem unlock and wait for the OKAY in the terminal window
Reboot your phone with fastboot reboot
Now, you will be informed that because of the unlocking your phone memory is "corrupted" (aka not decryptable anymore) so the phone needs to be wiped. Agree and wait.
Hopefully, your bootloader will be unlocked now. You can check that by returning to fastboot mode and checking that the Status is Unlocked.
If you want TWRP/root, check out this thread.
This procedure didn't seem to work until a few months ago so I don't know exactly if this procedure works only on newest Joy UI versions or not. Try it out (at your own risk).
IMPORTANT - if you can't unlock with these steps, please post here with the version of Joy UI installed and the message shown after the fastboot oem unlock command

Hey guys,
I think I found a way to unlock the bootloader on the Nokia 5.1 Plus. I didn't do it yet, but can someone please try it and see if it works?
Instructions:
1. Boot into recovery. I made a guide on how to do that in case you don't know how. Here's the link:https://forum.xda-developers.com/nokia-x5/how-to/guide-how-to-access-recovery-global-t4054561
2. Select reboot to bootloader.
3. Run fastboot oem unlock from adb terminal and see if anything happens.
PS. Running adb reboot fastboot from pc doesn't work-the phone just restarts-but rebooting to bootloader option from recovery actually gets it to fastboot mode.
If it works please tell me in a reply.

Hey don't post guides for other if you don't know what it means, You will get other people phones bricked.
FYI Nokia phones requires permission to unlock bootloader.
adb oem unlock doesn't work now a days for most of the phones as you know many companies has made rooting and changing roms difficult. (excluding OnePlus and Pixel).

For me it gave an error (FAILED (remote: unknown command)), where
Code:
fastboot flashing unlock
gave me an error on the device asking me if I wanted to unlock flashing or to cancel. I don't know if this helps anyone anything but it seems to have worked because if I run
Code:
fastboot flashing get_unlock_ability
I get the message (bootloader) unlock_ability = 1

Hi guys,
im looking forward to unlock the bootloader on my Cubot P30.
The phone is responding in USB debugging moder over the shell, for example when I´m typing "adb devices" or "fastboot reboot bootloader".
But in fastboot afer restart the device unfortunately doesn´t respond.
I even dont really know if the Bootloader is locked or not. The OEM Unlock slider under developer settings is set.
Furthermore The Recovery menu is in chinese, so i also dont know if there is a chance to doublecheck.
I tried flashing an Image over the Shell in case the booloader is unlocked but without success.
Also I cant´t find TWRP for this device, it seems there is no support for Cubot P30, isn´t it.
Hope there is a chance to update the device to Android 10 or Lineage, thanks in advance.
Update: The device is now unlocked. I flashed the Lineage 17.1 and unfortunately the device is still rebooting. Has somone a working image for this device?
Hello, how do you unlock your phone?
Mine Is P40 and same issue.
So if you tell me the way i really appriciate.
Thank you.

I've done the in-depth test and it's on the Fastboot screen but when I type fastboot flashing unlock in a command window it just shows me the help text for fastboot, which doesn't show any command or option for either flashing or unlock, so how can I get it to work if those aren't valid commands?
fastboot devices shows my phone, so the device is recognised.
EDIT: I'm still on Android 9 A.15. I understand that there's no unlocked for Android 10 yet.
EDIT: Nevermind. I was using adb/fastboot from the link in this guide, which is v1.3 https://www.ytechb.com/how-to-root-realme-5i-and-unlock-bootloader/
After I updated to minimal v1.43 from here it worked https://androidmtk.com/download-minimal-adb-and-fastboot-tool
My problem was same. But i successfully downgrade to color os 6. I guess you can try it too.
Enable USB Debugging and Allow unlock boot loader option in USB debugging.
Connect your mobile with PC and use following Command.
adb reboot bootloader
fastbook flashing unlock
Check mobile for unlock option.
How did you downgraded to colour os 6?

I don't know if you are still interested in accessing Fastboot but you can access it using a specific firmware version.
Still, let me tell you that unlocking the bootloader is virtually impossible. Since the well-known generic method doesn't work for the SoC SC9863A, you need to have a special Fastboot's program version and a dedicated private key that only they provide.... and I emphasize the word "dedicated" since apparently ZTE did not use a generic key to sign their ROMS. At least on this device.
Unless they decide to release the key or give support to unlocking the bootloader, all we can do is wait for them to change their minds. Because they don't want to provide it. I know because I tried to order it several times.
