Branding debranded P990i

Hello.
Is it possible to 'brand' P990 back, just by using the Restore GDFS
option in XS++ (I have a gdfs backup file (.bin) of my 'Orange brand' P990)
or should I use the GDFS script code like this one:

gdfswrite:0002079E01080000490109435843313632303337 02.....?

If the gdfs script code is necessary to change the CDA to the old one
(Orange brand), so How can I write it ?

Thx, Michal

write back your gdfs back-up then use seus, seus will detect the cda and write back the branded firmware.

So, I understood that I should use the 'Restore GDFS' option (where I select the .bin file with my old branded GDFS), instead of "GDFS Script" ?
