My nexus 5 just turned off and is stuck on the boot animation. I am able to access the bootloader and have already tried to wipe cache and performed factory data reset but the phone is still stuck on the boot animation. I have tried to unlock the bootloader with 1-click-nexus-5-bootloader-unlock as well as CF-Auto-Root-hammerhead-hammerhead-nexus5 tools but after I accept to unlock thebootloader, the phone reboots and gets stuck on the boot animation. The bootloader status remains locked.
I really need to fix this issue and I would be grateful if anyone could help me out.
Thank you
Okay instead of using those tools can you please go into bootloader and try unlocking it using normal fastboot commands (I think it's "oem unlock" or something to that effect). See what happens after that.

I tried the oem unlock method but it didn't work. Every time the phone reboots, it locks the bootloader.

This is a common sign on Nexus Devices that the memory chip is failing or has failed. This means it is a hardware issue, and cannot be repaired without exchanging the device, or replacing the motherboard.

Hi again folks,
Having some trouble re-locking my bootloader (so that I can return to stock completely).
I am unrooted, ADB works correctly but when I reboot into the bootloader to use fastboot the bootloader appears frozen and I can't do anything. The phone also does not appear on the computer/device manager when in the bootloader. There is also no text like (usb_init) at the bottom of the bootloader. It is almost as if it loads so far then freezes.
The reason I am returning to stock is because my power button is broke so going to get it fixed under warranty.
If anyone knows a fix on how to unfreeze my bootloader it will be greatly appreciated.
Are your volume buttons working?

Yes they were working. Phone is away to Samsung now to get a new motherboard.

For starters, if there is already an answer to this question, please point me in the right direction because I have looked all over the forums and cannot find an answer. I was wondering if anyone could help me return my Nexus S 4G back to stock. I was in the middle of using one click stock when my power went out and now my phone just sits at the bootloader saying "fastboot mode-no boot or recovery img" and one click stock does not work.; meaning, it will sit and ask me to put the phone into debugging mode. I have also tried manually flashing the files from fastboot but it sits at sending file but does not flash. Even let it sit at the sending screen for 3 hours but it never flashed.
Maybe a brick. The same thing happened to me once, no img's, fastboot not working and a broken power button. I just got it back from a free repair

Well, is your bootloader locked/unlocked? and try to do it manually with fastboot, at least you know that things are done correctly.
unlock bootloader is : fastboot oem unlock
lock is: fastboot oem lock
you could try to switch once and try to push the recovery image so you can flash a new rom.
Thanks for the help. I relocked and unlocked the bootloader and it did the trick. I was able to manually flash everything back to the phone
Glad I could be of help

Hi,
I got a Nexus 5 about 40 days back. The phone randomly switched off a few times. I performed a factory reset as suggested by the Google Support team and other forum posts here. Yesterday, the phone switched off. On going into the bootloader, I am able to view the different options. On selecting recovery mode, it just goes to a blank screen.
The phone is not rooted.
Please help me out.

Thanks for helping me out,
I did the steps as mentioned in the guide, but ran into a problem while unlocking the bootloader.
After entering the command, "fastboot oem unlock" the bootloader gets unlocked.
But on entering the next command, "fastboot reboot" it goes back to unlocked state.
How do I proceed?
thanks again
you said it went from unlocked to unlocked? did you mean goes back to locked?

Is phone's bootloader unlocked? Tried flashing a stock ROM from fastboot or with NRT kit?

Hi, I recently bought a N5 from another guy. The previous owner told me that it bootlops, and it does. So I tried to format and install stock Lollipop from fastboot: the phone is locked, so when I type "fastboot oem unlock" the phone shows the red line "LOCK STATE - unlocked", then, when I type "fastboot reboot-bootloader" the phone reboots again into bootloader and shows me "LOCK STATE - locked" so I'm not able to perform any wipe or flash. You can also see it from the attached pics. What can cause this?

Instead of using the command line, try rebooting into the boot loader manually with the power and bottom volume key.

TBH, no device should be able to lock and unlock itself upon reboot. I'm pretty sure it's borked

Tried now but nothing. Still "LOCK STATE - locked" after reboot.
Could you flash a factory image right after you unlock it?
Sent from my Nexus 7 using XDA Free mobile app
If it immediately re-locks, 99 times out of 100 means NAND is fried.

If I try to flash the new bootloader "fastboot flash bootloader..." after performing "fastboot oem unlock" and trying NOT to reboot, it sends the bootloader and when trying to write it shows up "FAILED (remote: flash write failure) as you can see from the screen.

If the NAND is fried it's a nearly hopeless case. You would have to replace a lot of your phone's components.

In my case the sdcard was fried. I had to sell the phone to another guy.
Hi , how can i confirm the NAND is fried ? I am in the same position as above.
I have the same situation, and would also like to know if there is a way to tell/test failed NAND. Is anyone can enlighten us? I'll really appreciate any help!
i have a nexus 5x that had a motherboard replaced under warranty but now it seems the nand is dead too cos i cant open the bootloader, it sets itself back to locked, could i complain and get it fixed under warranty?
I would complain because an unlocked bootloader is needed to flash a stock rom.

no. it isn't
the device reboots and the black screen with"fastboot mode" appears after giving the first command. But after giving the second command it doesn't moves ahead, I mean the confirmation message doesn't appears in which we are supposed to select yes or no by pressing volume up and volume down key. So, evrytime i try to unlock bootloader i use to stuck at that black screen and left with no choice but unplugging the device and taking out the battery. After i unplug my device the command prompt shows up a message, somewhat like this- "error <source<too many links>"
:/ please help...
In recovery there should be an advance option inside that you have reboot to bootloader option.

1) reboot system now

5)wipe data/factory reset
6)wipe cache patition
7) backup user data
8)restore user data..

Ok.
You must be using adb oem unlock command to do that previously.
In fastboot mode

Your bolt is not waste just find a person having same device and if he is roited say him to make a nandroid backup of his rom on your sd card and done. Take your sd card and restore from that. Your device will work like a new set and you will have both the sets
