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?
Sent from my Nexus 5 using XDA Free mobile app
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?

If you have old twrp backup of any rom which is earlier(in yout mobile not other mobile only your mobile don't try backup of other mobile if the mobile is same then also not try only your mobile backup) then to goto twrp hit restore and restore efs only

Use this method

Hello.
I have a Nexus 7 and doesn't work. The battery gone out and when I turn it on it hangs a screen with Google logo.
I have tried everthing. To enter in bootloader, try to restore the tablet and I have an error:
E: can't open file
E: failed to mount /cache (Invalid argument)
I have tried to reinstall Android from pc, but it hangs the tablet.
Do you know what can I do? I don't mind if I have to delete everything, I just want the tablet works again.
Thank you very much.
Regards.
Well I screwed up somewhere. I tried updating my modem and then it got stuck bootloop and now i keep getting that error in twrp no matter what I do I tried to return to stock but twrp can not find the restore as in this guide https://forum.xda-developers.com/le-pro3/how-to/guide-return-to-stock-lock-bootloader-t3539513. I tried flashing everything Manually except system.img as in this guide. https://forum.xda-developers.com/le-pro3/how-to/guide-how-to-manually-upgrade-firmware-t3609786. Still no dice. I'm unfortunately stuck and can't figure out how to fix this. All i have acess to is TWRP which always gives me that error Failed to Mount '/firmware' (invalid argument) and Fastboot. I'm sorry if this isn't posted right. I tend to not post very often. Thank you in advance My device is X727
