I am running an unrooted Nexus 5 with stock 5.0.1 on it.
I have managed to Brick my phone by not waiting for the cache partition to finish. It was taking around 5 minutes so I rebooted and that apparently bricked it. The phone will either go into recovery mode or get stuck in a bootloading. Recovery mode is mostly useless, it will not allow me to re-wipe the cache partition, volume up does not take me anywhere.
I tried using wugfresh's nexus toolkit to just factory reset the phone, but it will not work because the drivers are not working properly. Any help would be appreciated, I am so bummed I bricked my phone.
Fastboot flash stock cache image. Common problem, well documented

Okay, long story time. I had Android 4.0 on my phone which hadn't been connected the internet for 10 months. I updated to 4.4.0, then 4.4.4, then 5.0. Phone worked great, but my previously working root had been broken by the Android L update. I went and tried to fix it myself using tools I probably was not using properly and got stuck wiping the cache. I waited about 10 minutes then forced it to shut down. Got a boot loop on the reboot. ****. Rebooted to recovery, tried wiping cache again, nothing is mounting. **** **** ****. Go and flash stock 5.0 from google's site using fastboot. Boot loop again. ****. Try to wipe cache and dalvik agin. Unable to mount. **** **** ****. Tried tthis with like 3 versions of android stock roms from google with 3 different recoveries and nothing worked. No recovery can mount my cache or data or dalvik or anything.
Please help...
... wat?
forget that, it connected to my other phone through the ceiling...
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
Plenty of tutorials in the sticky's if you need to learn more .

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

thanks... problem resolved
Hi,
I'm trying to bring my N5 to life. It has bootloop on Google logo (sometimes stuck on android animation). When i got it it was stock and unrooted. Computer can see the device, adb and flashtool works fine. What i tried to do:
- erase cache and userdata,
- factory reset
- change recovery to TWRP (tried CWM too, both works)
- flashing the factory images (all from 4.4 to 6.0.1)
- flashing factory image using this tool: http://forum.xda-developers.com/goo...kit-v2-2-kwonggers-nexus-5-one-t2508817/page5
- fix persist partition using this solution: http://forum.xda-developers.com/google-nexus-5/general/guide-to-fix-persist-partition-t2821576 -when I'm doing this, adb see my device and after using these commands I got only something like: clean, 15/1024 files, 1109/4096 blocks, it is not asking my about repair or change anything...
Unfortunately, it still has got bootloop. I can't go into recovery when I'm using usb cable, I can start it only without cable and then plug it in. (When it is on and I'm trying to turn on recovery mode it has bootloop on Google logo).
Have you got any ideas what can I do now? Is there a way to fix it?
Try this: manually flash every partition from the stock ROM, including the userdata.img.
After flashing the userdata.img file, immediately boot into stock recovery using the power and volume buttons and perform a factory wipe.
Hey, thank you for your answer. Unfortunately after flashing every partition and factory wipe it still has bootloop. But before i did it, it wanted to charge my Nexus, I just plug USB and suddenly I realised that there is a Welcome screen! Everything was running good, WiFi was working... I turned on USB debugging and reboot it to check what happens, but it won't turn on again, now it is again with bootloop Any other ideas?
Hello all,
First time posting, long time lurker. Everybody here at XDA has been exceptionally helpful with every Android device I've owned. Whether I've had technical issues, or just wanted to try out some new ROM's or apps. I just wanted to take a second to thank you all before I got started with this post.
I've been pulling my hair out over this Nexus 5. It is my wife's phone that she never rooted, unlocked, or anything outside of generic user space.
I looked all over XDA and the web looking for solutions to this issue, but have been unsuccessful. Below is an overview of what's going on with my device.
___________________________________________
1: Nexus 5 repeatedly bootloops at initial Google logo
2: Bootloader locked - I can unlock it with fastboot oem unlock but it is reverted to locked at each restart.
3: Recovery mode bootloops every time cache is touched - Every time I attempt to sideload images or wipe cache recovery bootloops. This makes it impossible to flash factory images in recovery.
4: Problem seems to be with the cache - In fastboot I can wipe userdata, but when it gets to wiping cache I get an error.
5: Yes I have tried re imaging with factory images, flashing TWRP (doesn't take, ADB wasn't set to on before this happened and I think the bootloader unlock isn't really working, but Im not sure,) flashing stock cache, flashing stock bootloader etc.
Any idea's guys? This is my last attempt to fix before I just take the Nexus apart so I don't waste anymore time on it. I would be happy if I could get any functionality whatsoever.
Thanks so much,
Nathan
:Update:
I was able to boot into TWRP with fastboot boot recovery twrp.img.
Trying my luck here, it seems to have been able to wipe the cache, but not mount /data.
Unable to mount storage
Failed to mount /data (invalid argument)
