E:Can't open /cache/recovery/command

My phone is not experiencing any problems, however, I have noticed that when I go into the recovery utility, at the very bottom, it says " E:Can't open /cache/recovery/command"
Does anyone know what this means. Perhaps my recovery is corrupt or something.
When I installed Rosie originally, it came with a ROM and a recovery.img. I didn't know what to do with the .img so I did nothing.
I guess what I am asking is :
1. Is this a problem?
2. How could I fix it.
3. What exactly is a recovery....why use if you can just wipe or reinstall?
hi
yes how come it says E; cant open cache recovery command and it says E; cant open sdcard update.zip no such file or directory

My problème is that I tried to install CM10.2 stable on my G2 but after following the CM wiki, the phone stuck on CM bootloader, I can't mount or wipe cache partition from recovery and I have an anauthorized access for ADB from recovery !

(((SOLVED))) Galaxy S4 - Sph-720T - Failed to mount /efs (Invalide argument)

In recovery mode I am not able install any ROMS, theres the error Failed to mount /efs (Invalide argument)
I can only flash stock roms using odin, everything works on stock roms except for the wifi, after connecting/disconnecting multiple times, the wifi stops responding and wont work in the future

(( SOLVED ))
First thing you should do, is to backup your EFS if you still have it.
I had mine but it wasn't mounting properly.
In order to back it up, please download terminal emulator on a rooted device and follow this video
I would try to back it up, even if you think the efs is messed up... worst case scenario is you end up where you started, not worse off.
---------------------------------------------------------------------------------------------------------------------------------------------
Your device needs to be rooted.
1.) Download SDK tools here - Scroll down to the bottom and "Get just the command line tools"
2.)Install TWRP , Find your device, download the .tar and flash it using ODIN
Boot in to recovery, in TWRP you want to go to mount, make sure system, esf are checked.
3. If you installed SDK tools, go to c:\android tools\SDK tools. hold shift and right click on the area inside the folder and select run command line from here.
4.) In cmd, type
Code:
ADB devices
ADB Shell
SU
mke2fs /dev/block/mmcblk0p10
mount -w -t ext4 /dev/block/mmcblk0p10 /efs
5.) You should be good!!!

Help Rooting D805 4.4.2

Im all out of options, I have no idea what else to do. Here is what I've tried:
1. Used the ioroot but it shows device not found right after it reboots into recovery mode but no error shows up .
2.Tried an older version of ioroot but this came up:
Mounting system RW and pushing SU, then remounting system RO again
mount: Operation not permitted
failed to copy 'su' to '/system/xbin/su': Read-only file system
Unable to open /system/xbin/su: No such file or directory
Unable to open /system/xbin/su: No such file or directory
mount: Operation not permitted
3. Tried TowelRoot but shows that my device is not supported.
I have no idea what else should I do now :/ Any help is appreciated.
PS: I cant use the newer version of ioroot now, it just shut down by itself when I press any key to start it.
EDIT: Ok I had to manually use CMD to install it.
