Enabling OEM Unlock in Developer options doesn't unlock the bootlader, it simply prepares the bootloader to get unlocked via fastboot command.

Only I have a small problem I don't unlock my bootloader via fastboot when it doesn't work :/ It immediately jumps to my system when I boot fastboot, even with a command like ,,adb reboot fastboot"

I have new thread, where i am writing all info :/ https://forum.xda-developers.com/t/zte-blade-a7-2019-fastboot-mode-missing.4462035/

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.

fastboot cannot unlock bootloader

Hi,
I got into a frustrating situation, I installed Oneplus OTA update after that phone is stuck in bootloop, only thing I can access is fastboot, after reading many articles, I found that unlocking bootloader can fix my problem.
But unlocking bootloader has become worst nightmare in OnePlus one, when I run # sudo fastboot oem unlock, it will reboot phone and goes into 1+ logo, then I reboot the phone again boot into bootloader and situation is still the same bootloader is still locked.
I also tried OnePlus toolkit, onplus toolbox and oneplus tool for linux, nothing is unlocking the bootloader.
Phone is not enabled for adb (debugging mode).
adb shows "offline" mode while phone in bootloop logo.
is there any way I can atleast force the phone to unlock boot, any help is appreciated?
I am a linux user, but I aslo tried in windows, samething.
Thanks
I think you need to sit down and re-read the guide on how to unlock your bootloader because you're not having a good understanding on what you're supposed to do.
http://forum.xda-developers.com/showthread.php?t=2788632 Read that thread and adjust accordingly to Linux unless you do it on a Windows-based machine.

Hi,
Thanks for reply, I have followed the complete guide to unlock bootloader, I updated the android sdk to the latest with android drivers.
Find the attachment how I have done that, but still the bootloader is locked.
In device status it shows that device temperted: true, is there any way I can change that to false using fastboot command?,
maybe that is the thing preventing me to unlock the bootloader.
Your help is appreciated.
Thanks
Dani
I only used 15 second adb installer on my PC for adb drivers. That way I don't copy paste files into SDK folder.
Anyways fastboot OEM device-info gives back tamper true and what is the other flag?
Make sure u don't put in typo like your op "ulock" lol fastboot OEM unlock should bring up wipe options on your phone :s

Hi ek,
screen shots are attached with the reply to zephiK's message (all flags can been seen), however, fastboot oem unlock doesnt bring me wipe option (though I am ok to wipe).

After the fastboot OEM unlock command look at the phone, that is where the wipe stuff appears. Or it should.

activate developer options and select usb debugging and oem unlock, restart in fastboot mode connect the phone to a pc and in adb shell write: fastboot oem unlock

Does it show up when you type fastboot devices?
What guide did you follow?
What steps did you skip?
If you see your device in fastboot devices you can go to guides and use the fastboot rom thread to get it working.. That works if you managed to unlock the BL, I'm having a hard time understanding if u managed to unlock it or not...
Don't waste your time

Just Use Unbrick tool, it takes 5 minutes to bring any OP6 back to stock with locked bootloader, then upgrade back to Android Pie.

[UNTESTED] Bootloader Unlock On Nokia 5.1 Plus

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

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?

PGP signing TWRP doesn't work, private key needed?

Hello!
I am trying to sign TWRP (Redmi Note 8 ginkgo) using GPG on Windows 10. I have imported the TWRP public key, however, when I select the file for signing, it does not show up in the drop-down menu in Kleopatra. From my research, this seems to be due to it being a public key and missing the private key part (correct me if this is incorrect please).
I have no idea how to acquire such a key that would allow me to sign TWRP correctly. Could anyone please help me with this?
Thank you!
Well from my understanding are you trying to lock the bootloader with TWRP installed?

No, the bootloader is still locked and I don't have TWRP installed.
I want to use the command "fastboot boot twrp.img" in adb, however, it doesn't work with a locked bootloader. I get the error "FAILED (remote: Fastboot boot command is not available in locked device)".
I read somewhere that it might work if TWRP was signed without having to unlock the bootloader.
Well does your phone have some problems and cannot unlock bootloader?
The signing key is something only accessible by people working for Xiaomi, unfortunately.

1. Fastboot and ADB are 2 totally different softwares: don't confuse them.
2. You only can sucessfully apply Fastboot commands if phone's bootloader is unlocked. Hence unlock bootloader as 1st thing of all things:
Code:
adb devices
adb reboot fastboot
fastboot reboot fastboot
fastboot flashing unlock

Unfortunately, my phone no longer accepts the correct pattern to unlock it. I have been trying to find a solution for this for weeks, if only so I can back up my data before wiping it, but none of the options I found seem to work in my situation. From what I know, unlocking bootloader would delete everything, which is the exact thing I'm trying to avoid, so it is unfortunately not an option. :/

Thank you for the correction. I only started getting into this recently and I mostly saw them bundled together so I assumed Fastboot was part of ADB.
