Hi all, i am currently attempting to un-root my device using odin v3.07.

I run odin using the md5 file under pda and make sure that auto reboot and f.reset time is ticked but it always failes after this :

<ID:0/004> system.img.ext4
<ID:0/004> NON-HLOS.bin
<ID:0/004> cache.img.ext4
<ID:0/004> hidden.img.ext4
<ID:0/004> FAIL! (Ext4)
<OSM> All threads completed. (succeed 0 / failed 1)

and on the device it states the following:

ODIN : Invalid ext4 image

" does this mean the bootloader image is a downgraded version of the one currently installed" ??

i am unsure what to do as now the phone is without an os and wont boot into anything. can anyone help please.
