Nexus 5 stuck at boot animation - Nexus 5 Q&A, Help & Troubleshooting

Guys nexus 5 was working fine.. After uninstalling few apps i decided to restart the device so so i power off the device and then turn it back on ever since device is stuck at boot animation
Plz help me out

Unfortunately your device is locked, which means you will lose everything on it (hope you use cloud backups).
You can try one thing first. From recovery (third image), try wiping the cache partition. What happens? Same mount errors? If not, try to boot.
If it still doesn't boot, you'll have to flash the factory images, which involves having your whole data wiped.

This is a known problem. If wiping your cache does not help look here

[Q] [P6210]Boot Looping and Corrupt Data Partition

Been running CM10 and CWM 6.0.1.9 for ages with no issues and loving it. Yesterday morning (while on vacation) picked up the tab from charging and it was boot looping. Tried formatting cache and Dalvik cache as 1st attempt to fix and it reboots when trying to format Dalvik cache, regular Cache deletes just fine. Next reflashed CM10, but still boot loops. Started manually formatting partitions and when I get to Data it reboots.
So this sounds like Brick Bug, but shouldn't be since I'm on CM10/CWM6.0.1.9 and wasn't wiping when it occurred.
So questions for the braintrust...
1) Is there anything I can do to fix this while on vacation when the only PC I can access is Windows RT? Basically it needs to be something I can flash with CMW.
2) Assuming #1 isn't possible, my next step was to try flashing a stock rom when I get back home. Make sense or other thoughts?
Thanks,
Todd
try removing your ext sd card and boot it up. See if that helps. If not, I'd Odin the stock ROM
I have experienced this too. My fix was to delete data after reflashing CM10. I tried just clearing cache and dalvik like you did but it continued to boot loop. So I flashed CM10 because I was at school and it was all I have but it was still stuck and so I cleared data at CWM(Didn't flash CM10 again anymore). And yeah, it pretty much deleted everything, but I had a backup at home. It was fixed.

Thanks. Formatting data causes a reboot, so I think I'm stuck until I get back home and can use Odin.

For the sake of the archives...reflashing stock Honeycome fixed the partition problem and allowed me to re-install CM10.

Bootloop after Xposed module - what are my options?

Hi,
My Nexus 5 has been working pretty well until now. Earlier today I decided to disable lightflow and try the Xposed LED Control module. I installed and rebooted and it seemed to be fine. But then while using the phone shortly after unlocking it it completely froze then rebooted itself. Since then it's been stuck in a bootloop where it gets as far as the boot animation but then freezes for a few seconds and returns to the Google screen again.
I tried power off and back on and tried loading into recovery to see if wiping dalvik + cache might get me as far a boot but when it loads TWRP it asks me for a password (I've never set one nor enabled encryption of any kind) so my only option is to cancel but then it can't mount the partitions to wipe the cache.
I suspect it's the Xposed module I installed that caused this but I can't be sure it's not just coincidental. I haven't done anything else unusual on the phone today.
Is there anything I can do to fix this that won't require a complete factory reset? Is there any way I can at least backup or keep my data? Unfortunately I'm not at a computer where I can run or install ADB but if that would let me save my current setup or data I can do so at home tonight.
Thanks!
Try flash stock cache.img from fastboot
I don't see this being xposed related but who knows?!

I know clearing the cache asks for a password, but try to see if you can flash something. The something is the Xposed disabler zip file in the root of your scard.
Hi,
From the Xposed Framework thread:
In case you get into a boot loop:
You can flash the attached Xposed-Disabler-Recovery.zip by Tungstwenty. It will be copied to your (external) SD card when you install Xposed as well. The only thing it does is copying /system/bin/app_process.orig back to /system/bin/app_process

Maybe this..., the "Xposed-Disabler-Recovery.zip" should be at the root of /sdcard (at least for me it was the case).
You could try re-flashing recovery in fastboot mode to see if it fixes the password issue or also I believe philz touch recovery can read twrp backups if you want to switch to a different recovery.
The original bootloop seems like /data corruption to me (freeze + fsync perhaps), then the twrp password further evidences that but.... hmmmm

I think I was able to flash this. I keep getting errors about unable to open "/data/app-lib/com.h3r3t1c.onna" - rest off screen, then "Not a directory" and "unable to mount '/persist'", but it seemed to mount /system and flash successfully.
Unfortunately, this doesn't fix the bootloop.
I guess I'll try flashing the cache.img as suggested tonight and see if that works. If not, I guess I'll have to try and wipe.
If I do a factory wipe from TWRP, will I lose photos, videos I've taken? Restoring everything else will be a pain but it's really the photos that I haven't backed up yet I'm more concerned about.
Thanks!
Twrp doesn't wipe /sdcard

I just installed that module today and its working fine. I'm on the stock ROM. But doesnt Xposed put an Xposed disabler flashable zip file on your sdcard? Or is that something that maybe I just transferred over and forgot that I did. Because I dont remember transferring it to my phone or downloading it but I have it on there. If you have it, maybe try flashing that to disable Xposed and see if it boots.
EDIT: viking37 actually already suggested this.
Wiping or flashing cache didn't help either.
I tried a factory wipe, which didn't help.
Then I formatted data from TWRP and was able to boot but there were strange issues including a complete inability to connect to the cell network.
Also, TWRP kept complaining that it couldn't mount /persist
So finally I ran flash-all.bat from the factory image download to try and completely return to a factory image. It seemed to work but then I got into a bootloop where it reboots after upgrading android then apps starting.
I tried to do it again but now fastboot keeps giving me this error: FAILED (remote: flash write failure)
or if I try to wipe: FAILED (remote: failed to erase partition)
I'm starting to thing maybe it's a hardware problem with the internal flash... Is that likely or is there still something I can do?
Will I be able to RMA it in this state?
Thanks again for the help!

[Q] Nexus 5 suddenly refuses to boot, factory reset does not help, TWRP shows error

Hey,
I've been running several Lollipop ROMs on my Nexus 5 in the past few months.
Today my Nova Launcher suddenly stopped working and froze instantly on restart, so I rebooted the phone.
It got stuck shortly before ending the boot, after several seconds of those colored dots whizzing around the screen they froze.
This issue was reproducible, so I first cleared the Cache and Dalvik Cache and rebooted, same problem. I then tried to Fix Permissions to no avail.
I then erased System, Data, Cache and Dalvik Cache and reflashed my current L-ROM of choice, OptiPop.
The device still doesn't boot, same problem.
Now TWRP is showing an error in red font whenever I try to wipe or flash.
The error I'm getting is:
Code:
unable to stat '/data/data/com.google.android.feedback/cache/com.android.opengl.shaders_cache'
Does anyone have an idea on how to fix this?
Try reflashing TWRP and then wiping. If it still doesn't work flash the factory images from fastboot using either the script or ( optimally ) by hand one by one.
Your filesystem might have gotten corrupted well enough for TWRP not to make heads or tails of it.
If that still doesn't work search the forum for how to format the needed partitions - and triple check what you are formatting.

[HELP] Need urgent help with avoiding a data wipe...

Basically, my wife's phone was constantly rebooting. I had heard of power button issues so I tried to open the phone to fix that. After fiddling around with the button the problem persisted. I read somewhere that wiping the cache would help so I prepared to do that.
As I was waiting for the cache to wipe... the phone reboot again. It now does not boot (sits on the boot screen after the Google logo goes away) and says invalid argument when I try to wipe the cache.
According to this post, flashing the cache.img will fix the corrupt cache and allow me to wipe it.
Unfortunately my wife's phone has not been backed up, nor has the bootloader been unlocked. Is there ANY way to backup/retrieve files before unlocking the bootloader so I can fix the cache corruption issue? She has stock recovery, running lollipop.
Would really appreciate help in this matter, the pictures on her phone are from a year of travelling (not my best idea to leave them on her phone...but I digress).
If your phone keeps rebooting, and bootloader is LOCKED, its going to be hard to do anything to recover user data.
Having said that,
If you had ADB debug enabled before this disaster, you could try to ADB Sidleoad the Nexus 5 Lollipop OTA zip from stock recovery.
Then you data would remain intact.
Best of luck

I can flash custom recovery without unlocking bootloader or wipe. If the /data partition didnt get corrupted we could recover the files.

Has my brain gone broken? I thought you could fastboot stock img files without unlocking the bootloader?

You can try that too.
What version of Android did you have on the phone?
In order to flash factory images, you’ll need to have the Android SDK HERE
Then you need to download the same version of Hammerhead Factory Image
you have been running on her phone HERE
Extract the correct Hammerhead Factory Image using 7zip or other extractor tool.
Then copy the cache.img from the extraction to the SDK/platform-tools folder.
From within your platform-tools folder, open a command prompt.
I'd recommend wiping the partition before flash.
-First type the following command
fastboot erase cache
-Then type the following command
fastboot flash cache cache.img

OnePlus 8T stuck on boot

Hello, I was using my phone normally and then I decided to turn it off because I was having a bug with an application, then I turned it on but in that process I accidentaly push one of the volume bottons and end up on what it seems a boot menu, I went for the english option and then to "exit" and "power off" so I can exit this boot menu, but it comes back again to this menu over and over I don't know why,.
I go to boot reason and appears this: fs_mgr_mount_all
Unable to parse kernel log.
I need help, don't know why I can't exit this menu because I entered by mistake and did nothing else than trying to exit. I have never root my phone or anything related to that, please help me to not lose my data!
Try booting in Recovery and clear Cache (only wipe Cache not Wipe all) and then reboot
Maybe this help you

Ok just done that but it is still stuck on boot, maybe there is another solution to this problem?
Hmm looks like your 8T is caught in bootloop. As far as i know there is only to try in Recovery the Wipe All step which deleted all on your Phone. If that also not works then MSN Tool which has the same result as the Wipe All, the only differnce is that MSN Tool sets up your Partitions fresh and complete clean.
But i can be wrong with that what i Knowing, maybe a more smarter guy can help you out with your problem.
If your phone bootloader not unlocked, the only way i know is fastboot flash .img file from official full update.zip
If that not work, wipe or MSM, but they all causing data loss.
