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.

I received a new Nexus 5 yesterday and immediately enabled ART but did nothing else, such as rooting, unlocking, etc. Today the phone froze and when I rebooted it it was stuck in a boot loop. I attempted to enter recovery, but was met with a persistent black screen. I also tried to unlock the phone, but when I use the fastboot reboot-bootloader command, the phone reboots to a battery animation and is stuck there until I manually reboot the phone and the bootloader is locked again when I manually enter the bootloader using power + volume down. Any suggestions guys?
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 I cant use ADB because usb debugging is no longer active.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
I have unlocked my Huawei tablet using
Code:
oem shell
-> reboot fastboot
and later in fastboot mode:
Code:
fastboot oem unlock <pw>
now each time I am trying to enter the fastboot mode I get the
nasty "Your device has been unlocked and can't be trusted"
and throw me back to the regular boot.
Any idea what else I can try?
Code:
The info of my model is:
Named: Huawei M3 Youth
Model: CPN-AL00
Firmware: : MSM8940C00B056SP01M_AMSSJun28201718:26:30
Hardware ver: : SH1CHOPINAL0M-V2

Thanks for the reply but nop in HuaWei the gicky stuff comes with volume up button but in that case the
same thing I get the ugly text message and normal boot :/
Any other ideas?
Found it: you really hold the volume down and just plug the USB cable no other
actions required, it will turn on into the fastboot mode.
i have a insignia with same problem get nasty mess. bootloader error code 3 but can not get to boot to fastboot mode only factory recovery . in factory recovery mode i select reboot to bootloader and if just restarts again with same bootloader mess. error code 3
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.
Hey there,
I have a Pixel 3a, which refuses to start. After powering on, it directly hangs on the first google logo forever.
The device has stock rom and a locked bootloader.
I can still enter fastboot, but when I try to enter recovery mode from there I'm stuck at the google logo again.
Is there anything left I can do to revive the device?
- I cannot unlock the bootloader, because I need to the check this oem unlock setting which in turn is not possible whithout a working device. Or is there a different way?
- I cannot switch the A/B slot because the device is locked.
- I cannot flash something because the device is locked.
I'm grateful for any advice.

Hi there.
A couple of questions first:
Does it respond to any adb or fastboot commands?
Does it enter into Recovery or Rescue mode from Fastboot?
If yes, then your best bet is either https://pixelrepair.withgoogle.com/ or https://flash.android.com/
Both tools should work even with a locked bootloader, you just need Chrome and the USB driver.
Be warned tho, both tools will erase and factory reset your phone.
