E:failed to mount /cache (Invalid argument)

ASUS_T00F_WW_user_2.22.40.54_20151120_16

Issue with ADB:
E:failed to mount /cache (Invalid argument)

Followed Process:
1] ADB and Fastboot Files
2] ASUS FLASH TOOLS
3] INTEL USB DRIVER
4] RECOVERY IMAGE [WW_user_2.22.40.53]
5] Firmware [WW_user_2.22.40.54_20151120_16.zip]

Steps:
1. Installed all required drivers
2. Extracted Firmware and ADB/Fastboot, then placed boot.img,fastboot.img,recovery.img inside extracted ADB/Fastboot folder
3. Entered in to DROIDBOOT in phone by pressing Power & vol + and released power button once got vibrated.
4. From ADB/Fastboot folder started command prompt
ADB/Fastboot>Fastboot devices
1 match found
0123456789ABCDEF 1 device found

ADB/Fastboot>fastboot flash fastboot fastboot.img
ADB/Fastboot>fastboot reboot-bootloader
ADB/Fastboot>fastboot flash recovery recovery.img
ADB/Fastboot>fastboot reboot-bootloader
ADB/Fastboot>erase data
ADB/Fastboot>erase cache

Then selected Recovery using Power button.
5. Now system/phone got booted up and entered in to andriod belly icon, pressed vol- and just once pressed vol+.
6. System/phone displayed menus
reboot system now
apply update from ADB
factory reset
wipe cache partition

and below I can see list with
E:failed to mount /cache (Invalid arguments)
E:can't mount /cache/recovery/log
....
....

a big list of E:Can't and failed
7. Still I have selected apply update from adb

ADB/Fastboot>adb devices
1 match found
0123456789ABCDEF 1 device found

ADB/Fastboot>adb sideload firmware.zip

It enabled and went for 100%.

But in system finally I got again big list of E:failed to mount /cache (Invalid argument)...
