Unable to mount /cache and all in mobile

Hi Not sure if i can post here on the Android Phone OS issue, dint find any solutions on the android forums.. thought to give a try here

my phone has an issue and is not able to mount /cache, /format and all, and the OS doesnt not boot, even while trying to load a new OS it says:
Code:
"FAILED (remote: flash write failure)"

when i try mount them, it says invalid argument. i am able to see all the device files under /dev/block/ i see many softlinks.. below are the list. tried to change the permisions as well..

Please suggest, on how to mount them hoping this will fix my issue.
Code:
/dev/block/platform/msm_sdcc.1/by-name # ls -l

What is the output from the command:
Code:
ls -ld /cache /format

And, exactly what command or commands are being used to mount filesystems on /cache and on /format?

this is the exact output for mount -a

and

/etc # ls -ld /cache /data
__bionic_open_tzdata: couldn't find any tzdata when looking for localtime!
__bionic_open_tzdata: couldn't find any tzdata when looking for GMT!
__bionic_open_tzdata: couldn't find any tzdata when looking for posixrules!
drwxr-xr-x 2 root root 0 Jan 2 18:30 /cache
drwxr-xr-x 3 root root 0 Jan 2 18:30 /data

Code:
/etc # mount -a
mount: mounting /dev/block/platform/msm_sdcc.1/by-name/system on /system failed: Invalid argument
mount: mounting /dev/block/platform/msm_sdcc.1/by-name/cache on /cache failed: Invalid argument
mount: mounting /dev/block/platform/msm_sdcc.1/by-name/userdata on /data failed: Invalid argument

was able to mount one file-system manually and this is vfat not ext, while others are ext4,

Code:
/dev/block/platform/msm_sdcc.1/by-name/modem
                         64.0M     44.4M     19.5M  69% /firmware

below are the filesystems

Code:
/etc # df -h
Filesystem                Size      Used Available Use% Mounted on
tmpfs                   912.9M    128.0K    912.8M   0% /dev
tmpfs                   912.9M      8.0K    912.9M   0% /tmp
tmpfs                   912.9M         0    912.9M   0% /storage
tmpfs                   912.9M         0    912.9M   0% /mnt/secure
tmpfs                   912.9M         0    912.9M   0% /mnt/fuse
/dev/block/platform/msm_sdcc.1/by-name/modem
                         64.0M     44.4M     19.5M  69% /firmware

one other thing is /proc/modules is not available... fyi as suspecting OS corrupt..

And what lines are in the file used by mount -a that specify the options used when mounting /cache and /format.
# 5  
Old 01-31-2016
As said earlier this is mobilephone Nexus4 and below is the fstab on it.

Sorry for the typo.. /format is a mistake and is not available..



Code:
/etc # cat fstab
/dev/block/platform/msm_sdcc.1/by-name/cache /cache ext4 rw
/dev/block/platform/msm_sdcc.1/by-name/userdata /data ext4 rw
/dev/block/platform/msm_sdcc.1/by-name/system /system ext4 rw
/etc #


Code:
/etc # blkid
/dev/block/mmcblk0p20: UUID="57f8f4bc-abf4-655f-bf67-946fc0f9f25b" TYPE="ext4"
/dev/block/mmcblk0p1: LABEL="2.0.1701.06" UUID="00BC-614E" TYPE="vfat"

---------- Post updated at 04:52 AM ---------- Previous update was at 03:35 AM ----------

Just noticed, that it is showing internal storage as 0, suspecting the main filesystem/block was not mounted and that is stopping to mount /cache and all..


also not sure how to mount this

Code:
/dev/block/mmcblk0p20: UUID="57f8f4bc-abf4-655f-bf67-946fc0f9f25b" TYPE="ext4"

---------- Post updated at 08:46 AM ---------- Previous update was at 04:52 AM ----------

This is the OS it has...

Code:
~ # uname -a
Linux localhost 3.4.0-cyanogenmod-gc1d5adb #1 SMP PREEMPT Sat Jan 25 13:33:00 PST 2014 armv7l GNU/Linux
~ # blkid
/dev/block/mmcblk0p20: UUID="57f8f4bc-abf4-655f-bf67-946fc0f9f25b" TYPE="ext4"
/dev/block/mmcblk0p1: LABEL="2.0.1701.06" UUID="00BC-614E" TYPE="vfat"

---------- Post updated 01-31-16 at 04:22 AM ---------- Previous update was 01-30-16 at 08:46 AM ----------

Any suggestions Don,

Thanks in Advance
