bricked my moto g while downgrading lollipop to kitkat / corrupted data partition? topic

i was using moto g xt1033 asian retail, i changed it to 4.4.4 brazilian retail and then updated to lollipop 5.0 brazilian following a thread on xda. all worked well. i came across a thread which had an ota update for 5.0 to 5.0.1 it was a 10mb file. i put it in pendrive and flashed it via twrp. since then the phone never went past the warning bootloader unlocked page.

when i power it off, it automatically reopens but gets stuck on the warning bootloader unlocked page.
usb debugging is enabled, i can access bootloader, can use fastboot commands, it recognizes adb commands and can flash recoveries on it.
the only thing that doesnt work is that it doesnt get past the warning page.

so i went to twrp, cleared all- dalvick cache, data, internal storage, cache and system.
it gives wipe complete, FAILED
see image 1.

so i flashed the original 4.4.4 rom and it again gives the same errors and now i get waves on twrp, but still doesnt go past the warning bootloader unlocked screen.
updating partition details-
E : unable to mount '/data'
E : unable to mount '/cache'
E : unable to mount internal storage
see image 2.

basically, every time i try to wipe it or install a new rom it gives problems about partition.

so i wiped it again and installed cm11 snapshot on it.
again the same unmounting problems, but now it goes past the warning bootloader screen but always stays on the arrow rotating about the cm logo.


i searched a lot online , and i think the problem is corrupted partition.
so i followed this thread http://forum.xda-developers.com/show....php?t=2683787 .

first he shows a way by using terminal command from trwp . when i goto command terminal, it shows browse to starting folder i chose any folder like sdcard and enter this code

Code:

---

mke2fs -T ext4 /dev/block/mmcblk0p8

---

. it gives this
see image 3 and image 4.

i try the next alternative that is using adb and this code

Code:

---

adb shell
killall -19 recovery
make_ext4fs /dev/block/mmcblk0p8
reboot

---

and it gives this
see image 5.
