Default [Q] [T3buntu] - GT-P5210, Loop device

Hi

I'm trying to install this http://forum.xda-developers.com/show....php?t=2573441 on my freshly bought and updated GT-P5210 (rooted stock rom).

The script runs to the point where it has to mount the Image. (using the script from the post)

Code:
$bbox mount -t ext2 /dev/block/loop255 $mnt
This fails with 'invalid parameter', and if i remove '-t ext2' it fails with I/O error

Code:
u0_a157@android:/ $
u0_a157@android:/ $ cd /storage/extSdCard/Img
u0_a157@android:/storage/extSdCard/Img $ su
u0_a157@android:/storage/extSdCard/Img # sh /data/data/com.zpwebsites.linuxonandroid/files/bootscript.sh /storage/extSdCard/Img/t3buntuv1.2_20131216.img
Checking loop device... FOUND
mount: mounting /dev/block/loop255 on /data/local/mnt failed: Invalid argument
Error: Unable to mount the loop device!

Do I tell busybox to overwrite the 'mount' command?

I used TWRP for root/recovery instead of CWM if that makes a difference.

Best Regards

*Edit, turns out it was a bodged image file transfer
