Device: Yu Yunique
I flashed stock fastboot rom (YU OS) and it booted. After that, I did "fastboot oem lock" and phone not booting. fastboot not allowing me to flash another rom too.
I googled about this and it says I need to enabled USB debugging from dev tools. But since phone not booting, I am not able to do this.
Can anyone help please?

I have a Micromax A290 [Canvas Knight Cameo] which is rooted. I have installed adb and fastboot drivers in my PC running Windows 8.1. I am trying to unlock the bootloader of my device.
So I connect the device, type "adb reboot bootloader" and the phone boots into fastboot mode.
Next, I type "fastboot oem unlock" to unlock my bootloader.
The phone asks me for confirmation and I go for Yes.
Here is the problem.
After I choose yes, a message comes up in my device saying this:
"BOOTLOADER UNLOCK FAILED. RETURNING TO FASTBOOT IS 3s..."
I have tried everything I know. Used a different cable, used another port, but to no avail.
Please help me.
Thanks in advance.

Hi, i have asus zenfone go and it was working fine for few months, then it started bootlooping, now it shows first image and shuts down.I can get in bootloader menu, but can't go to recovery, it just shuts down.I've tried using adb and fastboot, installed drivers, but adb doesn't detect it, fastboot dectects it, but I can't do anything without unlocked bootloader, but when I type fastboot oem unlock and confirm on phone it fails to unlock.If someone can help me please answer.

hello, I have tried to unlock bootloader through fastboot, but I don't have permission. I found sp flash tool which can flash rom, but I wasn't able load stock rom scatter, so I downloaded some system backup of same phone, I flashed it, now my phone doesn't show anything on screen, I can still connect it through download mode and when i just connect usb to pc it keeps restarting(pc makes connecting and disconnecting sounds).I read that it is because I of bad rom, so if someone has stock rom which can be loaded in sp flash tool I would be thankfull if he could give me the link.
Sorry for my bad english.
Hello everyone,
first thank you all for this great forum! I solved many problems with your help, but now I have the first time a problem I must create a new thread.
I have a Moto Z which won't start any more. It boots to the Motorola Logo and does nothing. I can enter the fastboot menu, but can not flash anything because it was all original (Phone of my dad).
Now I tried to unlock the bootloader to flash twrp and lineageOS but it is not possible to unlock the bootloader.
I always get the info, Check 'Allow OEM Unlock' in Android Settings > Developer
Now the question is: Is there any way to "fix" this problem?
