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.

You could try to erase cache using fastboot and see if it can boot. If not try a factory reset.
If factory reset still doesn't work you'll have to unlock your bootloader, flash a custom recovery and resotre a nanadroid backup or flash a stock rom of 5.0.1.

you don't need usb debugging. Usb debugging is only needed to have adb connectivity when the phone is booted in android.
for gpe device you should be able to unlock it using fastboot from the bootloader.
Code:
fastboot oem unlock
If this method doesnt work you'll need to use HTCdev.com to unlock it.
Don't forget that unlocking your bootloader will wipe everything on your phone.

It have nothing to do with usb debugging! Like I said above, the only purpose of usb debugging is to enable adb connectivity when the phone is booted in android.
Even if usb debugging is turned off, you still have the ability to use fastboot commands from the bootloader (like you have tried) and to use adb commands from a custom recovery (which you don't have access to because of your locked bootloader)
With that said, I'm sorry to tell you that what you are seeing after doing "fastboot oem unlock" (PG_ERROR) is typical of the infamous GPE bootloader bug. This bug make impossible to unlock your bootloader from using oem unlock or by using HTCdev.com method. So your phone is bricked sorry.
you are not alone, see this thread: http://forum.xda-developers.com/showthread.php?t=2547894

Maybe keep it in a drawer and hope that HTC will release a 5.11.1700.3 or higher version official RUU so you'll be able to flash it with s-on and a locked bootloader.
or maybe you could ask the guys at fonefunshop if they are able to s-off it using their method which doesnt require to boot in the rom.
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
Guys I have been using Nexus 5 since the day it was released. This evening I was factory resetting my Nexus 5 after it rebooted it just got stuck on Erasing. I'm unable to go in recovery mode also as after booting into bootloader mode and selecting recovery it just shows andriod logo and erasing, it's more than and hour like this. Can anyone please help me out with it ?
Edit: The thing is USB debugging is not activated on my device and now fastboot is not recognising my Nexus 5 on my new laptop I think it might be because of either USB Debugg or Driver problems. Ay help would be appreciated.
Can you get into fastboot and unlock the bootloader? If the bootloader remains unlocked after a reboot, you could flash a stock rom. Unlocking the bootloader will wipe the phone.
To be clear, USB debugging has nothing to do with fastboot. It is a driver or cable issue if your computer is not recognizing it. Fix the drivers and try what audit13 said.

Thanks guys it worked.
Bought this device and everything works great and I have root. When I try to unlock the boot loader by going to "Developer Options" and checking the "Oem Unlock", I then
Code:
adb reboot-bootloader
At this point I do a
Code:
fastboot oem unlock
Which then the device asks me to use the volume buttons to confirm, Volume up for yes and volume down for no. The problem I'm running into is in fastboot mode it seems my volume up and power key are completely ignored. They work in recovery and in android but not in the boot loader itself.
I have tried unplugging the phone after sending the command over to see if that is a factor but it doesn't seem so. I'm only allowed to use volume down which denies unlocking the boot loader.
Another thing if anybody can get me a scatter file that would be much appreciated.

How did you root the phone?
Hoping for an answer to the bootloader question as well. For root I'm going to attempt kingoroot and replace with supersu
Ive been asked by a friend of mine to fix his nexus 5 that is stuck on a Bootloop, I've opened it up to have a look at the power button and that wasn't the problem, the device has not been rooted, the Bootloader is locked, there is no emergency mode and there is no recovery. I am however able to access fastboot and when I try unlocking via fast boot it does unlock but then requires a full reboot and as I've said before this cannot happen because of the Bootloop.
Any suggestions!?!?!?!
After unlocking the bootloader, does the bootloader relock itself? If it does, the memory chip is damaged and requires a replacement motherboard.
I've had this problem when I corrupted my recovery by using FlashFire and my bootloader was locked. Though I was able to restore my device using Fastboot. I had unlocked my device and instead of flashing the stock recovery when unlocking the bootloader I had flashed the Team Win Recovery Project recovery and when I tried to boot up to TWRP recovery it would stay for a couple of second displaying that it couldn't wipe the data partition and then reboot me back into bootloader mode. I fixed that when trying out the following steps:
1= Download the latest firmware of the device found Here .
2= Boot the device to Fastboot mode (aka Bootloader mode) plug the device in and unlock the bootloader (of coarse confirm when asked by the device).
3= After seeing that the device has stopped wiping data indicated the text "wiping..." in the very bottom of the specifications in the Fastboot Bootloader REBOOT THE DEVICE IN FASTBOOT BOOTLOADER MODE by navigating using Volume buttons to scroll down and highlight the option "Reboot Bootloader" and then pressing the Power button.
4= Using the provided scripts for Windows , Mac and Linux flash the device with the firmware.
VERY IMPORTANT: WHEN YOU SEE THAT IT IS FLASHING "userdata" and after that "cache" HOLD DOWN THE VOLUME DOWN BUTTON THIS WILL FORCE THE DEVICE INTO FASTBOOT BOOTLOADER MODE.
5= When you see that the device is in the Fastboot Bootloader mode scroll down (again using volume buttons) and highlight "Recovery Mode" then boot into Recovery and it should automatically start wiping the ("userdata" partition) Data once more that the bootloader said when it displayed the "wiping..." message after being unlocked.
If not wipe data factory reset the device manually by using the recovery and reboot to the system.
Optional: 6= IF the device has successfully booted up power it back down and lock the bootloader again using the fastboot tool additionally before locking the bootloader you can reset the warranty tamper flags.
This tutorial explains in detail how to flash a firmware to the Nexus 5 and shows how to restore the tamper flags.
I hope that I helped in some way.

Yes after unlocking Bootloader and restarting the device into the Bootloader it relocks and I'm back at square one
The motherboard needs to be changed. I recommend looking for a used Nexus 5 with a smashed screen and a working motherboard as this may easier than trying to find a new motherboard.

Thanks for the suggestion but I've tried this already and it doesn't work because when I unlock the bootloader and reboot into the Bootloader it locks itself again making impossible to flash the system image
