I can't unlock bootloader on my OPO. I tried command: fastboot oem unlock, and fastboot mode is responded with restart to TWRP.
Also I tried a lot of things that i found forums but they did not work. I can't flash anything.
I read somewhere that I can't unlock bootloader without OS installed, but I flash Cyanogenmod 11 (not 11s, and I don't know how), and then I got this problem: https://www.youtube.com/watch?v=jlhBVj89oxU , and my bootloader is still locked.
Does anyone have solution?

Hi,
I would like to know if there is anyone who knows how to unlock the bootloader on a TF300T with the Unrecoverable bootloader error. I have access to fastboot, yet the "fastboot oem unlock" command doesn't unlock the device.
The entire device is wiped due to following another tutorial for fastboot to recover from the bootloop error, so there is no more way to enter recovery or cold start android... the device has two options, fastboot mode, or being stuck at the asus logo untill the battery runs out. Adb doesn't recognise the device, even with windows drivers installed.
I can't flash anything with fastboot as the bootloader is locked.
Is there a way to unlock the bootloader, or is it gonna cost me repairs?
Grtz
I have owned this phone for about 5-6 months now and have never unlocked the bootloader. I know I probably should of done that when I got it but for some reason I have been able to flash TWRP, Root the phone, and install custom roms without wiping the phone no problem. I am currently on Paranoid Android 4.6 Beta 6 and TWRP 2.8 but I wanted to go back to CM11S, and I thought maybe it's time that I unlock the bootloader. I have installed the correct drivers and when I type "fastboot oem unlock", the Command Prompt said "finished in 0.06 seconds", I then rebooted and nothing happens. I also tried a Toolkit to unlock it but that didn't do anything either. Can anyone help? I don't want to Hard Brick my phone.
Thanks
It sounds like your bootloader is already unlocked.
Try running
fastboot oem device-info
to see what it says. Post your results here and somebody should be able to help you.
The right command is:
Code:
fastboot oem device-info

Okay so, first things first:
I can boot into both Recovery AND Fastboot
ADB Sideload does NOT work in my TWRP
Tampering bit is true and bootloader unlocked is false
My problem now is;
I need to unlock my bootloader because right now, my phone has no OS. I can't unlock it though because neither fastboot oem unlock works nor through the OPO Toolbox/Toolkit.
I can't flash anything to it right now and I need to find a way to unlock my bootloader, whenever I try to unlock it, it reboots to TWRP.
Please help. <3
adb push yourrom.zip /sdcard
Then just pick the ROM you just copied onto your phone storage using the above command in TWRP and you should be fine.
If that doesn't do the job then you can always use the brick recovery download tool.

Did you try flashing the OPO factory image and then start from scratch?
Tablet stuck in boot loop. Can get into fastboot mode but bootloader is not unlocked. I have tested some fastboot commands and they do work, just none which are useful in fixing the issue. Does anyone know of a place to obtain a bootloader code or any feedback on how to fix this? I have firmware downloaded and have tried the volume-/+ and power and that does not work. Just goes back to the logo page. Assume the only fix currently is through the fastboot. One other thing to note when I boot into fastboot it says PHONE unlocked, FRP unlocked which I assume meant bootloader is unlocked but does not seem to be the case.
Hi, i am loading booting to bootloader from adb with commnad (adb reboot bootloader) this isnt working, only restart its instantly switch to normal os, any ideas ?

Unlock bootloader if not done yet.
where i unlock bootloader ? In developer settings ? (i have unlocked)
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.
