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.

Hey guys...I'm having an issue.
I did the first step for rooting without the Recovery.img or Root.zip in the Folder.
Now I tried to do the reboot to go on the fastboot for 2nd step (recovery.img) and I get this error on my Windows:
QHSUSB_BULK
I believe it was because I had the phone plugged in. Anyway it was not going to fastboot.
So anyway I tried to do a factory reset too, and now fastboot is working, but I have no idea if it was because the phone was plugged in or because of the factory reset.
So, how do I know if the phone is bootloader unlocked or not after my factory reset?
What should I do?
Repeat Step one to unlock it again or do step 2? Thanks!
Is there any harm in doing fastboot oem unlock again just in case?
ok i believe its all done.
I have the phone rooted, should I keep debugging USB on?
Should I check the "Disable CM Recovery Protection" ?
Whats the best to do the OTA's without bricks or issues?
Hi guys!I have a weird problem on my HTC one.which is Google Play Edition.First of all,I was updating my htc to 5.0.1 lollipop which is official via OTA.It took a lot of time and I shut down the phone.And then everything is going to worse.It stuck bootloop unfortunately usb debugging is off ,and the phone is completely stock.(stock recovery,s-on,locked bootloader) I cant do anything due to this problem.I tried "adb push" and flash ruu but they also didnt work.How can I do?Thanks for helping.

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.
EDIT: so i tried a couple of things.. Everytime i unlock the bootloader and reboot it starts locked again (as if i never unlocked it), i tried to flash factory image using fastboot but gives me "flash write failure", tried flashing custom recoveries (both cwm and twrp) they flash fine but when i boot into recovery mode the stock recovery appears, so i tired sthg new : booting from the custom recovery without flashing... Cwm boots fine..fails to factory reset (it just gives error and reboots the phone especially when i try anything with the cache partition) so i went to boot twrp.. It takes half an hour to open twrp after its "teamwin" screen... But it helped me as it showed that : system and firmware partitions are working well (format /mount) but cache, persist and data partitions don't (no mounting and error while formating) plus data partition shows zero Mb size.... Basically any change i do either gives an error or dissappears on reboot..... Please helppp! ?

You can boot into recovery and do a factory reset. It'll wipe your data. Or you can unlock the bootloader, it'll wipe your data, and flash the factory image.

No, you'd don't need usb debugging enabled to unlock the bootloader. You just need fastboot on your pc. Google 15 second adb install xda. That'll setup fastboot. Then boot into your bootloader and from a command window on your pc run the command
fastboot oem unlock

Hi. My Nexus 5 is stuck at the flying dots after Lollipop OTA update. Already try factory reset. Can´t connect to my Lap (running Windows 10) because it says in the device manager: Unknown USB Device (Device Descriptor Request Failed), so I can´t manually update the driver and can´t access it with ADB and Fastboot tool. The device has no USB debugging enabled. In the old computer where I used to connect the device and has the drivers installed says the same thing in device manager as my new laptop. Please help.
So you can't boot into fastboot using the button combination?
Hi. Thanks for your reply. I can boot into fastboot with the buttons. I entered in recovery mode and do a factory reset but still stuck at flying dots.
Is the bootloader unlocked?

No, is locked
Here'';s a test: boot into fastboot and unlock the bootloader, reboot the phone into fastboot and see if the bootloader remains unlocked. If it remains unlocked, try flashing a stock ROM since you already did the factory reset.

Is there a way to unlock the bootloader without using a PC?
Not sure as I gave always used a pc to unlock the bootloader.
Was the bootloader unlocked before and it happen to relock itself?

No, always locked. I only installed OTA updates.
OTA updates will always work with an unlocked bootloader as long as the phone is running a stock recovery and is not rooted.
I asked about the unlocked bootloader because a bootloader that relocks itself after being unlocked in a good indication that the motherboard's emmc is defective and the motherboard needs to be replaced.

I never rooted or do anything to the phone, just OTA. Is dead anyway. Can´t do anything to fix it.
You don't have access to a computer to unlock the bootloader? I ask because an unlocked bootloader is required to flash a stock ROM.

I do but can´t do it. Is not detected in my laptop, my laptop send my an error that says that is not working properly and if I go to device manager it says: Unknown USB Device, and can´t update the driver. So is not detected in the minimal ADB tool and can´t unlock the bootloader.
Maybe try another computer, USB cable, USB port, or OS? Could the USB port be damaged?

Turns out the micro USB port was damaged and that´s why any computer was able to recognize the Nexus. It was replaced. Now I fixed the persist partition problem and booting for the first time in Marshmallow . Thank you so much for your replies. Take care
Glad you got the phone working. We're all here to help.
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.
