Hi threre,
Yesterday, my WhatsApp kept crashing so I decided to reboot my stock Nexus 4 (4.4.4). Now my phone is stuck in a boot loop. I have access to the recovery menus.
The first thing I tried was wiping my cache. When I open the Android system recovery There is already an error on the bottom half of the screen.:
Code:
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: Can't open 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
)
I have tried wiping the data and cache partitions but when I do that the same errors as above fill up my entire screen and it does not help anything at all.
Next thing I tried was to flash a stock image using this thread http://forum.xda-developers.com/nexus-4/general/how-to-how-to-flash-factory-image-t2010312. Since I am posting here you can probably guess that this did not work as well.
The problem is that my device is not rooted, and I can not get my bootloader to stay unlocked after a reboot. I have the bootloader drivers installed on my Windows 8.1 pc using the advanced reboot method so I have access to my phone in cmd. fastboot oem unlock does seem to work at first since the "'LOCK STATE" turns to UNLOCKED, but when I do the required reboot for flashing images it turns back to locked.
Perhaps this is a symptom of a bigger cache problem?
I am definitely not a pro at this but I have some experience with rooting phones from my Samsung Galaxy S II.
I really hope that anybody knows an answer other then try you warranty plan because then I will not have my phone for 5 days or more and I am not sure whether they really can fix this...
Lastly, here is the information displayed in my fastboot screen:
Code:
FASTBOOT MODE
PRODUCT_NAME - mako
VARIANT - mako 16 GB
HW VERSION - rev_11
BOOTLOADER VERSION - MAKOZ30d
BASEBAND VERSION - M9615A-CEFWMAZM-2.0.1701.03
CARRIER INFO - None
SERIAL NUMBER - xxx wil post this if nescesarry
SIGNING - production
SECURE BOOT - enabled
LOCK STATE - locked
Thanks in advance!
If you can't lock the bootloader that is a symptom of your emmc flash memory failure. Afraid there isn't much you can do. Are you still under warranty?

I still have warranty but I'm a little worried that they will complain about the damage (unrelated to the crash) of my phone. Is there no way of repairing the flash memory?

I know there's already dozens of threads with this problem but I've been going through them for three days now and I've pretty much given up trying to fix this. I'm posting here as a last resort.
All of sudden my nexus started shutting off or restarting and then it froze at the google screen, not the X logo like most people. I went into fastboot and then to recovery then tried the wipe data/factory reset option, doesn't do anything. Left it on that screen overnight and all that happened was the battery drained.
Now I'm stuck with in the android recovery screen because I kept trying to wipe it so much

I've downloaded sdk files, images and toolkits. I've done commands but I can only get up to unlock bootloader because it fails. I don't know what else I can do at this point, nothing seems to work. I've watched a video of a guy doing the wipe data/factory reset and it reset in seconds so I'm very frustrated with this thing. It's only 10 months old and I can't remember if I got a warranty or not and I don't even know how long a warranty is on these anyway.
Forgot to mention a couple things. When I try to wipe it, the android is frozen unless I press the power button and volume up again. Then the blue line and the little shape in front of the android start moving. There's no text here and the text freezes on -- Wiping data... Formatting /data and I never rooted it.
I am getting this same issue. The lack of replies is concerning.

The reason there are no replies is probably because there is no solution if people can't help they won't comment and clutter up the board with useless posts. Tell me everything you can about your situation is your bootloader unlocked? Rooted? What ROM are you on? Can you access fastboot mode? Ect and I will see if I can help

I was on cyanogenmod 11 4.4. I had many random reboots and was going to do a factory reset through recovery, it was freezing too much to reset through Android. I used Nexus root toolkit when I rooted/ installed CM11. Now when I try to use the toolkit I get fails and trying though recovery gets me the E: failed to mount errors.
Nexus 7 Wifi (2012)
unlocked bootloader (still shows unlocked on "google" screen
Was Rooted
I can access fastboot mode.
I tried to flash via fastboot and was unsuccessful.
Thanks for your help.
What error message do you get when you use wugfresh NRT back to stock and unroot with the option for soft bricked
Edit: It just occurred to me the most common reason for flashing failing or "failure to mount" is a corrupted nand memory, a bit like bad sectors in a hard drive.
Nand going bad could produce the spontaneous reboots and would explain why you are unable to reflash it.
The only option if that is the case is RMA or a new motherboard.

Recently, my Nexus 4 has been crashing randomly - shutting off with no warning or notice. It has always rebooted back up without issues. Last night, however, it just got stuck in a boot loop - spinning balls for hours on end.
Bootloader and Recovery Mode come up with no trouble.
The phone is and always has been pure OEM/stock. I've only ever updated using built in OTA process.
I tried to reflash to stock using Wug's Nexus Toolkit, but it repeatedly failed saying the device was locked. I tried to unlock the bootloader, but that seems to require a reboot to take hold, and every time I tried the reboot it would loop again.
In Recovery Mode, I get the following:
E:failed to mount /cache (Invalid argument)
E: Can't mount /cache/recovery/log
E:failed to mount /cache (Invalid argiument)
E:Can't mount /cache/recovery/last_log
E:can t open /cache/recovery/last_log
E:can t mount /cache/recovery/last_install
E:can t open /cache/recovery/last_install
I have downloaded the full image and tried flashing the cache, and system with no effect. Toolkit doesn't show an error, but nothing changes.
Does anyone have any suggestions? I'm at a loss.
Did you try
fastboot erase cache.img
fastboot flash cache cache.img
Then perform wipe data/factory reset before booting into android.
