hello all!
i need some help converting gdfs.bin files to gdfs.raw


i have a k790 with " not network coverage" problem. i made a backup og the gdfs with xs++ when it was cid52, but i upgrade the phone software using SEUS. i dind't knew the consequences of doing it. well to make the long story short....
i need to write the GDFS to the phone and the only way of doing it (free way) is with a tutorial a found of writing gdfs with far manager, but the gdfs hace to be in .raw format. i had even tried xs++ v4.1 in ubuntu with no luck....

if any one knows a way of converting gdfs.bin files to gdfs.raw pleaseeeeee let me knoww.
