Bricked? "E: Failed to mount" - Nexus 7 (2013) Q&A

So for some reason my tablet decided to reboot and it got stuck on the Google part of the restart animation.
I ended up going into recovery mode and now if I try to wipe the cache or do a factory reset, I am getting the error:
E: failed to mount /cache (Invalid argument)
E: Can't mount /cache/recovery/log
E:Can't open cache/recovery/log
Has my device been bricked? Any advice would be greatly appreciated.
Stock ROM, not rooted, 4.2.2

See if anything in this thread helps you, in short, if the fastboot suggestion given by AndDiSa can't help you, then you may be looking at sending it to asus (or google if you got through them directly).

I had the similar problem with my tablet and I couldn't wipe any partition (but it was after flashing custom recovery or sth.). After reflashing stock ROM in fastboot mode this problem disappeared.

[Q] I think I bricked my KF

Ok people so I think I F***** up royaly. I had my KF for months now and swaps plenty of roms on i butthe other night I was flashing a rom and accidently erased everything off the KF. Now it won't boot flashed rom. It says installaton success but follows with e: cannot load or something in that effect. I finally got my computer to recognize KF and mount but it won't boot custom rom. it'll either stay stuck on the triangle screen, back to TWRP or boot but screen stays black. Idk what else to do . I tried dozens of things and I feel that my head is going to explode. Please someone help.
Btw when using KFU I get
ABD status offline
Boot Mode 0x5003
Anyone?

Did you remember to wipe system and factory reset before flashing the ROM?
yea I did. after it's done installing it says
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/last_log
E: can't open /cache/recovery/last_log
E: cannot load volume /misc!
E: failed to mount /cache (invalid argument)
what am I doing wrong?
I finally got it to boot but now it's stuck on the boot animation..
Scratch that, I finally got it to work. Got it to normal boot. kept freezing on me but instead of holding the power button, i rebooted thru twrp. Did the latest update thru KFU , rebooted and did sustem wipe and factory reset, reinstalled and currently running Cyanogen Mod 9 Thanks for the help soupmagnet
In recovery, enter the following commands and post the results
Code:
adb shell
parted /dev/block/mmcblk0
print

[SOLVED] E: Can't mount /cache/

I just rooted my phone and got S-Off. Once I had that I installed CWM recovery v6.0.4.7
I booted into recovery and tried wiping data/factory reset but it froze. When I boot back into CWM recovery I get the following:
E: Can't mount /cache/recovery/command
E: Can't mount /cache/recovery/log
E: Can't open /cache/recovery/log
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
My phone won't boot (remains at HTC logo screen) and it won't let me install my CM10.2 rom because it also freezes.
Where did I go wrong?
**************************************
I was able to boot into ADB
I pushed the latest TWRP recovery onto my phone
I wiped data again (this time no errors)
I flashed CM10.2 and Gapps using new recovery
I'm back in business!

I have bad news for you. If none of those methods that you tried worked, it probably means you have a fried storage which is probably the cause of the Recovery not being able to mount the partitions as it cannot find any.

That could be one solution, however, What problem are you encountering while flashing a stock OS?

Have you tried to flash a custom recovery to see if that does the trick?

Galaxy Tab S myriad of problems

So, I've got a Galaxy Tab S 10" (SM-T800X), its the retail demo version and I've been trying to remove the retail demo firmware, I can't factory reset the device because the option is greyed out. So far I've had no luck, I've tried using Odin to install a stock ROM but that doesn't do anything. I've tried going through recovery mode to wipe the device and it says that MDM doesn't allow factory reset. Tried running Odin a few times in case it just wasn't working the first time. I've now encountered a new problem where its stuck on the Samsung logo when I try to turn it on, even after running it through Odin, and whenever I boot it into recovery mode I get the message
E:failed to mount /data (Invalid argument)
can't mount '/data' (Invalid argument)
E:failed to mount /data (Invalid argument)
E:Can't mount /data/log/recovery_lot.txt
E:failed to mount /data (Invalid argument)
E:Can't mount /data/log/emmc_checksum_log.txt
I'm at a loss as to what I should do here, I don't use android and have never rooted a device so I've just been reading what I've found on the internet to attempt to solve it.
Anyone got any ideas what I should do now?

You need to install TWRP. Factory reset within TWRP, reboot to Download mode then install the stock firmware with odin.
