We perform the IMMO OFF Using the hex editor. Where the following lines are modified
We open the editor and look for the following line:

IMMO ON	IMMO OFF
68 42 2D 03	68 40 2D 03

With the search engine you search for codes 68 42 2D 03 (search as many times as necessary)
And the value 42 will be modified by 40. (do it in all those found by the magnifying glass)
We proceed to save.
