[Q] Nexus 5 is stuck on boot screen with the circles after automatically turning off - Nexus 5 Q&A, Help & Troubleshooting

Left my phone to charge over night and woke it up finding it turned off. (You can imagine the shock!!)
I turned it on back and it has been stuck on the boot screen with the flying dots since then. (Annoyed!!)
When I go into recovery mode and try deleting cache or wipe data I get a lot of error messages saying can't mount cache/recovery/log
Can't unlock boatloader to flash stock. It keeps relocking upon each restart.
Each time I wipe I get these error messages.

Can someone please help me. I am really frustrated. Please don't tell me it's a hardware problem....

Um this sounds like a hardware problem. Sorry

Your NAND is fried. Definitely a hardware issue. RMA in you only option.

I feel like crying right now. My phone does not have any warranty.

I've been compiling NAND failures for the last few months - am I right to assume your phone was 100 % stock?
So far, my WAG is related to the ftrim. We do know they've improved the way it works in the last couple of updates - and made it more aggressive as well.
That does track well with the emmc casualties I'm seeing. But it could be a red herring as well - wear and NAND quality being the most obvious factors.
I wonder, how many of the failures occurred after a night-long charging ( which triggers ftrim) ?

Yes 100% stock and unrooted.
I don't know. I woke up and found it turned off. Then I got a bunch of error messages when I tried wiping cache and data.
Is it by some chance possible to save my phone??? I really need to know. I've been up searching the web. I realize I'm not alone now.

No. The memory is bad. Sorry man those are the facts.

By normal means? A straight and categoric no. In theory we could try reformat it externally, maybe even read it but... It's not gonna happen - at least not affordable.
Buying the emmc chip and replacing it is doable - but again probably not affordable if u don't already have the tools.

In a recovery there is an option which is apply update from ADB. Neither that can help me???

Instead of buying parts to fix the device, you should look into getting a new replacement

[Q] Weird Recovery Stuff

I have some weird stuff going on and I was wondering if maybe someone could tell me what it means. My phone is running fine, in fact better than ever. But when I reboot into recovery mode, and before I apply update.zip and I am in stock recovery (blue), I get the follow message below all of the recovery options (error message is in red):
E: Can't mount /dev/block/st111
(Invalid Argument)
E Can't mount /dev/block/mmcblk0p1
(Invalid Argument)
# MANUAL MODE #
E: Can't mount /dev/block/st111
(Invalid Argument)
E: Can't mount /dev/block/st111
(Invalid Argument)
Then, when I do a backup through CWM, everything goes through fine and then I get this message:
Back complete!
E: Can't open /cache/recovery/log
E: Can't open CACHE:recovery/log
When I go into CWM recovery, I do see a backup labeled with the correct date and everything, so I guess it is backing up correctly? Not quite sure what to make of it.
Ignore it.

I've had this happen and it happens when you have lagfix enabled and try to revert/odin back to a stock kernel (non voodoo) you'll need to follow the manual disabling procedure (of lagfix) by injecting an empty file named "disable lagfix" into the clockwork folder on your SD card then reboot. After that you should be clear to do a clean flash to get everything working properly. If you tried restoring right now it would probably give you an MD5 mismatch, and trying to flash from recovery would probably give you dev/block errors and it would cancel installation until you get your file system back in order.

OK that makes sense. I was flashing all over the place trying to fix that radio issue. Although I liked Add's answer better. Much more convenient

What planet are you living on mate??? Its nothing to do with a damaged memory chip. Its cause a flash failed and the boot loader is looking for a partition that doesn't exist cause its not all there.
If you must post please make sure you have a clue what you're posting...

Nexus 5 crashes and doesn't open

I have waked up and noticed that the phone is stuck on google logo, i tried to restore factory settings but that was not applicable
so i followed that post http://forum.xda-developers.com/showthread.php?t=2513701 to unlock the bootloader and install factory rom
after several tries my mobile phone can't start and when it starts the apps begin to crash one after the other, I noticed that the mobile recognize a memory of 250 MB (although I have a 32 GB storage) and I think thats the problem
Now I can open the recovery mode but the following errors appears:
E:failed to mount /cache (Invalid argument)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:failed to mount /cache (Invalid argument)

E:failed to mount /cache (Invalid argument)
E:Can't mount /cache/recovery/last_install

The internal flash memory module (32GB) of your phone.
Same thing happened to me. Was stuck in loading screen. Reset to factory settings. My apps would crash and I cant connect to my network. I also followed that same guide but it didn't help.
Yep, phone's internal storage is probably dead. RMA!
Just curious: for how much time did you use your phone before crashing? Was it completely stock?

thank you>>
Sounds like a bad emmc get a warranty replacement I see this a lot from the nexus 5
Yeah, you can try reflashing stock and what not.... But if you just bought it... I'd get it replaced instead.

Friend od mine had the same issue. It is emmc failure. There is nothing you can do about it. Had to be send for replacement. In other words flash memory is dead.

Try flashing just the cache partition through fastboot.

Try relocking your bootloader with fastboot oem lock, them reboot the bootloader. If it stays locked, then try LG Flashtool. If it reverts to being unlocked after the reboot then your eMMC is damaged and you'll have to RMA.
Well, my Nexus 5 had a similar problem, but mine was unable to mount /persist.
So all thanks to this, my Nexus 5 was saved. You might want to try this if that doesn't work.

hello,
It is by default locked.when i hit fastboot oem unlock,bootloader is unlocked but after reboot in bootloader it stays locked.Does LG Flashtool works in my case?

Probably not but you can try. Most likely you'll have to RMA.

Recovering data from Bootloop?

Hi all,
First of all, my phone is completely vanilla, no rooting or modifications were done. Running 5.0
Here's my situation:
After fully charging the phone yesterday and sending some messages on whatsapp, I drove out to get food and while on the way there, the phone blacked out. At first, I was able to get to the colored dots loading screen but it would always get stuck there and shut off. Then I keep trying to restart it up and it got worse and worse, now I'm always stuck at the GOOGLE screen. I'm not sure if this is a boot loop issue as it just gets stuck at GOOGLE screen. I tried the recovery mode cache wipe and it gets stuck at the GOOGLE screen in the middle of the wipe, or blacks out.
So this morning, after fiddling around the power buttons some more, I am able to get the battery logo while charging, though it is weird that it shows 100% then completely drained the next minute or so. I try to load into the recovery mode again and this is what I see at the bottom
E: failed to mount /cache (invalid argument)
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: failed to mount /cache (invalid argument)
E: Can't mount /cache/recovery/log

E: failed to mount /cache (invalid argument)
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
E: failed to mount /cache (invalid argument)
Am I screwed? I'm not sure what to do at this point.
Today, I am stuck at the colored dots boot animation but after smacking the power button side a bit, I'm back to being stuck on the Google screen. What's worse the recovery mode can't be maintained on the screen as it blacks out after 5-10 seconds. What can I do at this point?
I was going to use WUGfresh to reflasth the ROM but I think this wipe all data on he phone? Is there anything I can do at this point to retrieve all my apps, photos and what not? Nothing is backed up.
Any tips or advice would be greatly appreciated.
Thanks
