[Q] Cannot mount bricked nexus 7 2013 storage

Hello all,
I'll give a quick introduction of what my situation is, and then my problem:
I have a Nexus 7 32g wifi model with:
Product name - flo
Variant - flo 32g
HW version - rev_e
Bootloader version - flo-04.02
Carrier info - none
signing - yes
secure boot - enabled
LOCK STATE - locked
All of the following attempts are made by my macbook air - I can try with my windows machine but I personally do not think that this will help. please tell me if you believe that using a windows machine will fix it and I will go with it.
Recently I was using my nexus as an ftp server and was transferring some videos to it. when I left the shower I noticed it was stuck on the google logo, so I left it in case it was frozen etc. I then went to work and came back around 11 hours later to see it on the same logo (it was charging so naturally didn't run out of battery and go to a blank screen).
I therefore decided to see what was going on, clearly it wouldn't boot. I went into the boot loader and also successfully went into recovery mode. Following some instructions from google, the first thing to do was to wipe the cache partition. This returned the following:
--Wiping cache...

Following this I tried the 'apply update from ADB' option and this also was unsuccessful. After adb sends the image (and I've tried a few such as the stock one from google and CM10) to the nexus 7, my nexus says the following:
Now send the package you want to apply
to the device with "adb sideload <filename>"...

I returned to google to see what I can find and, although I can't find an identical situation to mine, I saw suggestions to unlock the bootloader, so I used fastboot with the following command:
./fastboot oem unlock
Click to expand...
Click to collapse
My terminal was stuck on "erasing userdata" for a very long time. judging by some of the screenshots I've seen, this shouldn't take more than a couple of minutes - I waited approximately 2 hours and then restarted my nexus.
I think it's worth mentioning that fastboot can see my device (matching my serial no) but running the adb devices command shows nothing under the list of devices. I have also tried to flash a recovery image, but this was also unsuccessful. I know there's a flash.bat file as part of the stock compressed folder, however I haven't touched that yet.
As a result, I think that the issue is with my storage and that it is not mountable. I may be incorrect here but I tried to remount the device through ADB - as mentioned above however, it can't detect the device so this never worked. I do not know how to get mount this using fastboot (I took a look at fastboot help but didn't find anything for that) so I'm not sure where to go now.
I believe that my device is now out of warranty (or very close to it) and I don't think the department store I purchased this from would help me so I'd rather not go down that route.
I hope the information I gave above was sufficient and I'd appreciate any input you have for this. I'm pretty average at terminal commands and have a good understanding of Unix, however I'm not an expert, so excuse me if I'm missing something that is under my nose.
Many thanks,
Ehab

Have you tried different USB cables? USB ports? Check if there is an update for the sdk available? If all else fails, try the Windows machine.

I was using the Twitter app and then my N7 rebooted. Now I have the same error on my device!
Do you think the internal drive is dead?
I need to check my warranty now!

Hello all,
So I tried the above but no success. This leads me to believe even further that it's an issue with unmounted storage. Has anyone had anything like this?
Thanks,
Ehab

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?

Unable to mount storage in TWRP, unable to open '' to wipe crypto key

Hello everybody,
I'm facing an issue with my phone. I was running Fulmics Rom 6.1 on my LG G3 for a few days, when, this morning, I woke up to find my device caught in a bootloop. I had a recent TWRP backup, so I tried to restore it, but it failed with the error : "Unable to wipe System".
I tried to wipe everything but my SD Card and got :
Code:
Failed to mount '/data' (Invalid argument)
Failed to wipe dalvik
Updating partition details...
Failed to mount '/system' (Invalid argument)
Failed to mount '/data' (Invalid argument)
Failed to mount '/cache' (Invalid argument)
I tried to use "Format Data" in TWRP Wipe Section, but got :
Code:
[B]Unable to open '' to wipe crypto key[/B]
Unable to wipe Data.
[B]Unable to format to remove encryption.[/B]
Updating partition details...
Failed to mount '/system' (Invalid argument)
Failed to mount '/data' (Invalid argument)
Failed to mount '/cache' (Invalid argument)
Flashing the Rom again fails as well as it stays stuck at this step :
Code:
Install new system
Extract:/tmp/unpackbootimg
I'm using TWRP 3.0.0-0.
Any idea about what I could do next ?
Thanks a lot.
