You just download the game without updating the 10gb data in-game because the game always ask you to login first and then proceed to ask for updating the game. I did that before and it doesn't seem to work. Just download the game, open it then log in and don't do any update, only download 10gb data in-game if you managed to log in without any issues, so remember to make sure and reopen the game after you do all the stufg multiple times to check if the login works so that if any issues occur, you can do the whole process again. At least thats how it went for me
