Possible brick.. need assistance from a guru!

Ok so I have a asus transformer tf300t and I have been using Kat Kiss Roms for quite awhile.
I am using TWRP v2.8.1.0 and I have never had ANY issues. I was running KatKiss Lollipop 5.1.1 v29
well I was working with an app I downloaded to create a short video, anyways it crashed the tablet and started to boot but sat at the KatKiss logo for a very long time. I booted into TWRP and noticed it showed 0gb space on my internal storage. I was not able to mount or run a restore.
Here is what TWRP was showing
E: could not mount /data and unable to find crypto footer.
E: unable to mount '/data'
E: unable to recreate /data/media/folder.
Updating Partition details...
E: unable to mount '/cache'
E: unable to mount '/data'
E: unable to mount storage
E: unable to mount /data/media/during GUI startup
E: unable to mount '/cache'
Kernel does not have support for reading SELinux contexts.
E: unable to mount '/cache'

E: unable to mount '/data'
MTP Enabled
E: unable to mount '/cache'
E: unable to mount '/cache'
E: unable to mount '/data'
E: unable to mount '/cache'

Is there anyway to fix this? I was searching but I wasn't sure which one to follow... and I have never attempted to recover a "bricked" tablet since it has never happened.
Any help would be GREATLY appreciated!!!!

I have tried to wipe cache partition and do a data/factory reset, but without any luck.
When I try to do a data/factory reset it says:
-- Wiping data...

I tried to flash again from the sdcard, same errors appear. Lauching a file manager from sdcard is impossible too.
Concerning ADB, the phone is detected, but flashing give an error. Odin doesn't detect the phone.
Anybody can help me ?
Thanks in advance

J710MN Stock rom "No Command"

I can use every rom just fine. However, I need to flash stock rom but when I boot to stock rom it says "No Command". After a minute or so, the screen changes to installing system update, which flashes to black every second.
Stock firmware that I flashed is "J710MNUBS4CSF1_J710MNICE4CSD4_J710MNUBS4CSG2_HOME.tar.md5"
When I press Power + Vol up in the "No command" screen, this is what the text reads:
