Bricked phone internal memory corrupted ? topic

Hi, first of all sorry for my english.

I'm S-off, rooted, using TWRP touch and android 5.0 (from ivanich).
I went out of memory on my internal storage, so I had a pop-up that says lower your storage (my sd card couldn't be mounted). Then i went in recovery to wipe cache and data for it would free some space, but I got theses issue:

mount: failed to mount /dev/block/platform/msm_sdcc.1/by-name/userdata at /data: No such device
unmount of /data failed; no such volume
script succeeded: result was [0,200000]
updating partition details...
E:Unable to mount '/cache'
E:Unable to mount '/data'
...done

I also tried by advanced wipe> wipe Data and I went stuck on this :

"Formatting Data using make_ext4fs function"

If i try to reboot on the rom it's bootloop

I tried a few command in the terminal command that I've found here http://forum.xda-developers.com/show....php?t=2683787

mke2fs -T ext4 /dev/block/mmcblk0p8

I get this :

filesystem too small for a journal
writing superblocks and lifesystem accounting information : done

This filesystem will be automatically checked every 37 mounts or 180 days, whichever comes first. Use tune2fs -c or -i to override.

So I have no idea how to fix this I never had this error before and I can't find anything about it, only Odin but correct me if I'm wrong but Odin doesn't work for Sensation ?
Thanks for any help I appreciate
