Help SE K790 GDFS problem

[vash200708]

sorry for a very late respond to your reply senter.

i just want to clarify one thing before proceeding with the instruction you made for me and for the other that will have the same issue. if i backup my corrupted GDFS before doing the procedure in setool, and lets say after following the steps you made i WRITE a WRONG SCRIPT in my GDFS in other words i crew it up (means i kill my own k790 T_T). now my k790 is DEAD but i have a corrupted GDFS backup before writing the GDFS in setool, can i revive my k790 if i restore the corrupted GDFS backup that i made?

thanks for your kindness in making a procedure that will fix my problem with my SE phone, i know its risky but i really like to try it.
