hm, zasto si stavila mbn i fbn file u own_custpack folder?
ne trebaju biti tamo, u tom folderu treba biti samo extractan custom..
a sto se tice patcha, evo generator patcheva: http://www.4shared.com/file/zxzJfdvU...kPatchGen.html

EDIT: ajd ti napravi i backup GDFS-a(ako vec nisi, za svaki slucaj)
p.s.
sa jednog tutoriala:
Once you've got the firmware, open the Custpack and extract it (with Folders!) to the own_custpack folder in the XS++ directory.
Make sure that your phone is charged 100%!
Once you've done that open XS++ and then connect your phone.
It should automatically go to the Flash tab.
Tick 'Flash Main Firmware' and browse to the MAIN file. (It should be a .mbn file)
Tick 'Flash File System' and browse to the FS file. (It should be a .fbn file)
Tick 'Customize File System' and in 'Phone Model' select 'Own custpack'
