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 I cant use ADB because usb debugging is no longer active.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

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
Hello, I have problem with my softbricked Nexus 5.
phone is full stock
bootloader is locked
USB debugging is not enabled
Android 6.0.1
all buttons are working
USB socket is fine
Factory reset from recovery mode is not working - still bootlooping
My purpose is to bring it to live, but I am stuck. Due to locked bootloader I have to use LG Flash Tool. Some time ago I used it with my other Nexus 5 and it was fine - worked excellent. Now I want to do it again with other phone but I am stuck on start: Can't enter download mode (volume up+usb cable). When I am trying to enter to download mode,charging battery icon appears and after few seconds my phone is being recognized as MTP USB device in device manager. I thought it is a problem with the phone, but tried with another working Nexus and there is no difference - it looks like problem with phone-pc connection to me. I tried few cables (original samsung and nokia) and two pc's - no difference. Tried all USB ports etc. Clean reinstall (with registry keys delete) doesn't help, updated version 4.2 neither. Do you have any ideas how to fix it?
Download mode? Never heard of that on the Nexus 5. There is a fastboot mode for flashing stock ROMs and to unlock the bootloader.
I recommend unlocking the bootloader and using NRT to flash a stock ROM.

I have NRT but problem is that to unlock bootloader I have to enable USB debugging - I can't do it with bootlooping phone.
Bootloader can be unlocked without enabling debugging as you are not running adb commands, you need to run fastboot commands.

Thanks! Can I do it with NRT also?
Easiest way to unlock the bootloader on a windows machine is to do this:
make sure that the necessary fast boot drivers are installed;
boot phone into fast boot mode by holding down volume up, volume down, and power;
connect the phone to the computer;
type "fastboot oem unlock" without the quotation marks and press enter key.
Unlocking will wipe the phone.
Once unlocked, you can flash a stock ROM using fastboot commands.

Ok I did it. Do I have to proceed "fastboot reboot" command? when I am doing it it reboots and still bootlooping. When I enter bootloader it is locked again
If the bootloader relocks itself when the phone is rebooted, the memory chip is damaged and will need a motherboard replacement.

How did you brick your phone. What happens when you choose recovery?

After Flash Stock Rom with "Tool all in one" there´s a Question to Lock the Bootloader. I clicked yes ...
When I´m in Fastboot and select Recovery the Phone will start new, but only shows "GOOGLE" for 0,5sec, than black screen for 20sec, again "Google" for 0,5sec,...it repeated for 10minutes
Same when I will Start the System.
Only Fastboot Mode shows correct.

the windows device manager i installed google android bootloader interface because i cannot install the oneplus specific driver it exits with error message
I cannot go to recovery mode from fastboot nor change any setting like enable oem un-lock or usb debbuging option
Any chance to unlock and flash the with new image
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
Please how to unlock bootloander and Root oneplus 8 in OS 11.0.8.8 ?
Thanks
To unlock bootloader download platform tools on you pc and boot into fastboot mode. Then connect your device to the pc and open cmd in your platform tools directory and run fastboot oem unlock. Then use volume buttons to navigate and power button to select.
Ps: All your data will be lost when you unlock bootloader. So backup all your data before you proceed.

You'll also need to enable "OEM unlocking" in the developer settings.
