THANK YOU VERY MUCH
couldnt get it working with resigning via kg but used the .pfd, master.bin and data.bin file.
made a save on ps3 for tanker to plant complete chapter, moved save to usb, copy and pasted your 3 files over mine (just normally without any software), opened kg and just clicked update. copied back over to ps3 and loaded up with no update data installed and running from EU disc.
resigning your save to mine through kg was leading to save becoming corrupt. i also dont remove the original from the usb what so ever as this was causing issues as well.
hope this helps anyone confused like i was
*forgot to add that corruption may have happened as i was changing the region when trying to resign,
by making my own save and only using those 3 files i didnt need to change the saves region at all. could be why it works
