Hello,
My phone keeps bootlooping.
Never installed any rom, I can't access the device in order to enable developer options and usb debugging.
I tried installing TWRP via fastboot, tried "fastboot oem unlock" via fastboot aswell but with no success.
Tried "MI unlock" via fastboot but without developer options enabled it won't work.
Please help me.
Thanks in advance.
Best regards Daniel Ribeiro

After messing around with my shield last night and not being able to get root access on cm12. I tried to reinstall one of the ota updates from a while back. Now I am bootlooping and when I try to boot into CWM it looks to be corrupted and doesn't load. I cant use ADB because usb debugging is no longer active. Does anybody have any suggestions to re-install recovery or somehow enable debugging or am I dead in the water here? Any help would be greatly appreciated
Is your bootloader unlocked?
Can you get into fastboot mode?
HW method:
Turn off the device
Press and hold "Back"+"Home"+"SHIELD" buttons till device boots
Click to expand...
Click to collapse
If you can get into fastboot mode and your bootloader is unlocked, you can use a command like "fastboot boot recovery.img" to have the device boot a recovery.img from your computer without flashing anything.
If you can get into fastboot mode, but your bootloader isn't unlocked you could try unlocking your bootloader, but this will wipe your data - so only try this if you don't have anything important saved. The command is "fastboot oem unlock".

The bootloader is unlocked Whenever I try fastboot mode the device is not recognized because USB debugging is disabled .
Update: Fixed
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.

If you don't see the OEM unlock setting in developer options then there isn't anything you can do to unlock the device.
What's the Baseband Version on the device? You can find that under Settings-->About-->Software Information
