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 I cant use ADB because usb debugging is no longer active.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 Nexus 5 phone which was not turning on a few days back. I kept it aside so that battery drains fully.
Now when I turn on the phone, it is on Google Logo Boot-Loop. When I press Power and Volume Down, I can boot into fastboot mode.
In fastboot mode, the device says it is locked and i send the following commands:
fastboot devices
fastboot oem unlock (Select Yes on Screen and Confirm as well)
fastboot reboot
Click to expand...
Click to collapse
After this, ideally the bootloader should be unlocked, but the phone still remains in boot loop and when put into fastboot mode, it again shows device is locked.
I don't know what all is happening. Is there anything I can try now? Even fastboot boot recover.img is not working as phone boots into custom recovery for some time and then reboots automatically.
Ehy guys im having some trouble with my OPO.
First of all i can't boot to the OS, it just stuck in bootloop, and recovery is not accessible, but i can use fastboot.
Ive already used the MSM8974 tool, but after the flash the device is still stuck in bootloop.
I can't even unlock the bootloader, if i try the fastboot command "fastboot oem unlock" it just reboot and nothing happens.
Do you have some advice to exit this situation?? Ty for the replies

Enable Oem unlocking in developer options
@Tab E mercy but i can^t exit out of the fastbood mode to chagne the settings i`m locked inside this bootloader mode and cant do anything else but try with fastboot oem unlock...
Try
Code:
fastboot devices
fastboot reboot
@jwoegerbauer the commands work the oneplus is rebooting into the fastbood mode again i need to exit the fastbood mode because maybe the os deleted and can only use fastboot mode to flash it or else i dont know how to exit the fastboot.
I don`t know if developer mode is on or if oem lock is unlocked but since i cannot go back into the oss of the system what can i do to recover the device completely
i`m stuck in this fastboot mode and no commaand is helping to get out of it what is the solution_maybe to take out the battery it is really hard have you had the same issues?
Whether phone should run in ADB mode or Fastboot mode or Recovery mode or ADB Sideload mode is set via a kernel flag read by bootloader when phone boots up. Pulling out phone's battery doesn't change this flag.
Typically to boot Android in NORMAL mode you run
Code:
adb devices
adb reboot
Hey guys, the dev device i have is stuck in the bootloader mode and i see device state locked.
I tried with latest platform tools
fastboot devices-->see it -> fastboot flashing unlock says ERROR. not alowed -->fastboot flashing unlock_critical-> Unknown command
odd.. is there a way to save it?cause is see that it works when you can boot in the device then go to unlcok..but im my case it does not boot at all..
